RESUMEN

Trigeminal neuralgia (TN) is a debilitating condition characterized by severe facial pain. Various surgical interventions are employed to manage this condition, including microvascular decompression (MVD), percutaneous radiofrequency rhizotomy (PRR), glycerol rhizotomy, percutaneous balloon compression (PBC), and stereotactic radiosurgery such as Gamma Knife radiosurgery (GKRS). This review synthesizes the outcomes of these interventions to provide an understanding of their efficacy and associated risks. MVD, known for its high initial relief rates, shows substantial long-term effectiveness, with recurrence rates varying based on patient demographics and comorbidities. GKRS offers significant pain relief with a favorable adverse event profile; however, recurrence rates increase over time, necessitating repeat procedures for sustained efficacy. PBC demonstrates high initial success, but pain recurrence is common, especially in patients with atypical TN. PRR provides immediate relief with a manageable recurrence rate and is particularly suitable for elderly patients and those with comorbidities. Glycerol rhizotomy, a cost-effective procedure, yields comparable outcomes to other interventions but requires careful patient selection. This review highlights the importance of tailored treatment approaches based on individual patient profiles, emphasizing the need for precise diagnostic criteria and careful patient selection to optimize outcomes. Long-term follow-up and the potential for repeat interventions are critical considerations in managing TN surgically.

RESUMEN

Facial pain is a common but complex complaint, frequently associated with dental issues or temporomandibular disorder (TMD). However, rare aetiologies can complicate conventional diagnoses and treatment approaches. We present a case of a 36-year-old male with persistent jaw pain and restricted mandibular movement, initially managed as a typical TMD case. Conventional treatments yielded no improvement, prompting advanced imaging, which identified an unusual mass within the lateral pterygoid muscle. A surgical excision of the mass was performed, and histopathological examination revealed a rare and unexpected diagnosis. This case highlights the importance of considering uncommon conditions in the differential diagnosis of TMD and facial pain to ensure timely and appropriate therapeutic interventions.

RESUMEN

Persistent idiopathic facial pain (PIFP), previously known as atypical facial pain (ATFP), is a chronic pain disorder with the characteristic of persistent, undulating pain in the face or the teeth without a known cause or any structural correlation. Women are more commonly affected than men. We report a case of a 38-year-old married female patient with a history of Crohn's disease who presented to the oral and maxillofacial surgery (OMFS) clinic with chronic dull bilateral facial pain and headache mainly affecting the right side of the face and neck without a known cause. She was initially diagnosed with PIFP due to a badly decayed right wisdom tooth. Wisdom teeth were extracted secondary to vague complaints of discomfort due to wisdom teeth; however, no significant improvement was noticed. Further investigations were carried out with new CT scans and magnetic resonance venography (MRV), which revealed evidence of having idiopathic intracranial hypertension (IIH), described as increased intracranial pressure with facial pain, headache, tinnitus, and papilledema. The patient was referred to neurology and received appropriate treatment. She began her treatment with topiramate, then transitioned to acetazolamide, underwent bilateral botulinum toxin (botox) injections into the temporal region, and underwent regular follow-up. The patient was significantly improved. Idiopathic intracranial hypertension must be ruled out in cases of PIFP that do not respond to ordinary treatment measures.

RESUMEN

Persistent idiopathic dentoalveolar pain (PIDAP) is a type of disease that, despite affecting thousands of people globally, negatively impacts patients' quality of life because of its unknown cause. Notably, the disease has a high prevalence rate and is primarily prone to middle-aged and senior individuals. Efforts have been made to gain the understanding needed for the accurate diagnosis and prompt treatment of PIDAP cases. This case report discusses the challenges faced in diagnosing and managing PIDAP after dental implants. The present study involved the case of a 62-year-old male patient, previously operated on for an implant at position #11, who suffered from chronic pain but no specific cause could be identified. We used an evaluation strategy to gain insights into the patient's illness, including antibiotic treatment, crown replacement, and continued pain. We prescribed nortriptyline 10 mg, and there was an improvement. This finding suggests that nortriptyline 10 mg QHS eliminates chronic pain.

RESUMEN

OBJECTIVE: Patients with type 2 diabetes mellitus (DM2) may develop carotid artery stenosis (CAS), requiring surgical intervention. Nerve injury following carotid endarterectomy (CEA) is a rare and often unrecognized post-operative side effect. This case report describes the diagnostic process and rehabilitation course of a patient with greater auricular and trigeminal neuritis symptoms following internal CEA. METHODS: The patient is an 81-year-old woman with DM2 who underwent a left internal CEA. She subsequently developed swelling in her left neck and face, and pain along the greater auricular and trigeminal nerve pathways. Pertinent examination findings included incision placement across the path of the greater auricular nerve and cervical lymphatic vessels that drain the face, with overlying scar adhesion. A course of physical therapy was initiated 12 days after surgery, and included mobilization and manual lymphatic drainage, modalities, and application of kinesiotape. RESULTS: The Patient Specific Functional Scale (PSFS) improved from 10/30 at evaluation to 27/30 at discharge. Swelling and pain were significantly reduced, with patient reporting no difficulty with sleeping, chewing, or talking at discharge. The reported pain level consistently correlated with fluctuations in face swelling throughout treatment. CONCLUSION: Patients with DM2 may present with symptoms of cardiovascular disease, requiring invasive surgical procedures. DM2 can cause damage to neural and vascular structures, predisposing patients to nerve injuries or hypersensitivity following procedures. This case report demonstrates a likely connection between post-operative facial swelling and nerve irritation in the head and neck. Mobilization and manual lymphatic drainage, modalities, and kinesiotape were effective to reduce pain and swelling. IMPACT: Physical therapists are uniquely qualified to identify, evaluate, and treat post-operative swelling and nerve pain associated with CEA.

Patients with type 2 diabetes mellitus may develop carotid artery stenosis (CAS), requiring surgical intervention. Nerve injury following carotid endarterectomy (CEA) is a rare and often unrecognized postoperative side effect. Physical therapists diagnose and provide treatment to patients with greater auricular and trigeminal neuritis symptoms following internal CEA.

RESUMEN

PURPOSE: Inferior alveolar nerve (IAN) and lingual nerve (LN) blocks are commonly performed using the intraoral landmark techniques. However, these methods have a risk of unanticipated nerve and arterial injury or a higher failure rate. We developed a novel extraoral approach for the IAN and LN blocks, the "inferior alveolar nerve block mandibular angle approach (IANB-MA)," using ultrasound guidance. The mechanism of action of this nerve block was examined anatomically, and its clinical feasibility was reported. METHODS: We performed the IANB-MA on four cadavers using different dye volumes (2, 4, 6 and 8 mL). The ultrasound probe was placed on the lower edge of the mandibula of each cadaver, and the needle was advanced to the mandibular inner surface. Blue acrylic paint solution was injected, and its spread was evaluated by dissection. RESULTS: Our study showed that the medial pterygoid muscle fascia was stained in all cadavers. The dye reached the LN consistently, and the IAN was stained with higher volumes (6 mL and 8 mL). The pterygomandibular space was filled with 6 mL and 8 mL of the dye. The IANB-MA successfully reduced pain in three patients with trigeminal neuralgia, tongue or jaw pain. CONCLUSIONS: The IANB-MA is a novel ultrasound-guided approach to the IAN and the LN. The clinical feasibility and effectiveness of this technique were confirmed in our patients. It may be a good alternative analgesic approach to other conventional approaches.

RESUMEN

OBJECTIVE: Cryotherapy ablation of the posterior nasal nerve (PNN) for treatment of patients with refractory chronic rhinitis (CR) is associated with postoperative facial pain and headache. This study sought to understand factors that may contribute to the development of this adverse effect. METHODS: Patients undergoing PNN cryotherapy ablation for refractory CR at a single institution from January 2018 to August 2023 were included. Demographics and clinical characteristics were collected via chart review and interview. Student's T-test and Chi-square tests were used to assess the significance of quantitative and categorical data, respectively (alpha = 0.05). RESULTS:  Forty-eight patients underwent cryotherapy ablation. Twenty-eight patients (58%) reported having facial pain and headache (adverse effect group) immediately post-procedurally. The average age of the adverse effect group was 54.9 years (SD: 17.8 years) which was significantly lower (p=0.002) than the asymptomatic group (69.7 years, SD: 8.7 years). Female patients were significantly more likely to experience this adverse event than males (p=0.04). Moreover, Caucasian females were significantly more likely to experience this adverse effect when compared to all patients experiencing the adverse effect (n=15, p=0.04). Previous diagnosis of migraine disorder was more common in the adverse effect group (28%) compared to the asymptomatic group (15%) but not statistically significant (p=0.26). Previous migraine, trigeminal neuralgia, or headache disorder diagnoses were not significantly correlated with adverse effect prevalence (p = 0.26, 0.24, 0.15, respectively). CONCLUSION: Given the relative immediacy and severity of this adverse effect, physicians should strongly consider these factors when counseling and selecting certain patient groups for this procedure.

RESUMEN

BACKGROUND: Disorders of the trigeminal nerve, a sensory nerve of the orofacial region, often lead to complications in dental practice, including neuropathic pain, allodynia, and ectopic pain. Management of these complications requires an understanding of the cytoarchitecture of the trigeminal ganglion, where the cell bodies of the trigeminal nerve are located, and the mechanisms of cell-cell interactions. HIGHLIGHTS: In the trigeminal ganglion, ganglion, satellite, Schwann, and immune cells coexist and interact. Cell-cell interactions are complex and occur through direct contact via gap junctions or through mediators such as adenosine triphosphate, nitric oxide, peptides, and cytokines. Interactions between the nervous and immune systems within the trigeminal ganglion may have neuroprotective effects during nerve injury or may exacerbate inflammation and produce chronic pain. Under pathological conditions of the trigeminal nerve, cell-cell interactions can cause allodynia and ectopic pain. Although cell-cell interactions that occur via mediators can act at some distance, they are more effective when the cells are close together. Therefore, information on the three-dimensional topography of trigeminal ganglion cells is essential for understanding the pathophysiology of ectopic pain. CONCLUSIONS: A three-dimensional map of the somatotopic localization of trigeminal ganglion neurons revealed that ganglion cells innervating distant orofacial regions are often apposed to each other, interacting with and potentially contributing to ectopic pain. Elucidation of the complex network of mediators and their receptors responsible for intercellular communication within the trigeminal ganglion is essential for understanding ectopic pain.

RESUMEN

Gradenigo's syndrome (GS) presents with the classical triad of otitis media, facial pain, and abducens nerve palsy as a complication of petrous apicitis. However, in the era of increased antibiotic use, complications of petrous apicitis have become infrequent and cases of GS are not frequently seen in clinical practice. We present the case of a 76-year-old man with uncontrolled diabetes mellitus presented with a two-month history of worsening right-sided headache, right-sided facial pain and weakness, along with dysphagia, hearing loss, and right otalgia with intermittent otorrhea following a right upper molar extraction. Imaging identified the inflammatory changes and indications of petrous apicitis. Although GS has become quite rare in recent years, this case highlights the importance of the responsible use of antibiotics in treating a seemingly innocuous infection.

RESUMEN

Unknown in origin, Bell's palsy is a common acute facial nerve paralysis that is usually characterized by unilateral facial weakening or paralysis. People of all ages are affected by this illness, which peaks in the fourth decade of life. Although the precise etiology is yet unknown, viral infections - particularly type 1 herpes simplex virus - are frequently linked to the problem. Based on the evidence of abrupt onset facial weakness and the elimination of other neurological diseases, the diagnosis is essentially clinical. The goals of management techniques are to lessen related symptoms, encourage nerve regeneration, and lessen inflammation. Corticosteroids, antiviral drugs, physical therapy, and supportive measures are available as treatment alternatives. The majority of patients experience spontaneous recovery within weeks to months, and the prognosis is generally excellent. Nonetheless, a portion may experience long-term consequences, highlighting the significance of individualized follow-up care. Bell's palsy is succinctly summarized in this abstract to aid in better comprehension and well-informed clinical practice decision-making.

RESUMEN

BACKGROUND: Population-based studies examining the prevalence of trigeminal neuralgia (TN) and persistent idiopathic facial pain (PIFP) are rare, and data on TN prevalence in Türkiye are very limited, with the prevalence of PIFP being unknown. This study aimed to determine the prevalence of TN and PIFP in Türkiye. MATERIALS AND METHODS: This population-based epidemiological study has a cross-sectional and descriptive design, and it was carried out in Afyonkarahisar, Türkiye. Participants aged 18 years and older were screened by using a self-assessment form to determine potential patients with TN or PIFP. RESULTS: A total of 19,237 individuals were included in this study, of which 17,223 responded to the survey questions. TN was diagnosed in 17 individuals, and the prevalence of TN was calculated as 98.5 per 100,000. PIFP was diagnosed in 35 patients, and the prevalence of PIFP was calculated as 202 per 100,000. The mean age of the patients with TN was 54.29 ± 12.98 years, the mean age of patients with PIFP was 49.80 ± 16.10 years, and the female-to-male ratio was 1.13/1 for TN and 2.18/1 for PIFP. CONCLUSION: The prevalence of PIFP in Türkiye has been reported for the first time by this study. Additionally, a much higher prevalence of TN was found when compared to previous study.

RESUMEN

OBJECTIVE: Advancements in deep brain stimulation (DBS) devices provide a unique opportunity to record local field potentials longitudinally to improve the efficacy of treatment for intractable facial pain. We aimed to identify potential electrophysiological biomarkers of pain in the ventral posteromedial nucleus (VPM) of the thalamus and periaqueductal gray (PAG) using a long-term sensing DBS system. MATERIALS AND METHODS: We analyzed power spectra of ambulatory pain-related events from one patient implanted with a long-term sensing generator, representing different pain intensities (pain >7, pain >9) and pain qualities (no pain, burning, stabbing, and shocking pain). Power spectra were parametrized to separate oscillatory and aperiodic features and compared across the different pain states. RESULTS: Overall, 96 events were marked during a 16-month follow-up. Parameterization of spectra revealed a total of 62 oscillatory peaks with most in the VPM (77.4%). The pain-free condition did not show any oscillations. In contrast, ß peaks were observed in the VPM during all episodes (100%) associated with pain >9, 56% of episodes with pain >7, and 50% of burning pain events (center frequencies: 28.4 Hz, 17.8 Hz, and 20.7 Hz, respectively). Episodes of pain >9 indicated the highest relative ß band power in the VPM and decreased aperiodic exponents (denoting the slope of the power spectra) in both the VPM and PAG. CONCLUSIONS: For this patient, an increase in ß band activity in the sensory thalamus was associated with severe facial pain, opening the possibility for closed-loop DBS in facial pain.

RESUMEN

OBJECTIVES: The aim of this superiority trial was to investigate the clinical outcomes of arthrocentesis as an early treatment supported by use of an occlusal splint vs use of an occlusal splint only in the management of temporomandibular joint (TMJ) arthralgia. METHODS: Ninety-five adults presenting with TMJ arthralgia were recruited into the study and randomised into 2 groups: Group 1 received arthrocentesis as an early treatment supported by use of an occlusal splint, whereas group 2 received treatment with an occlusal splint only. Seventy-four patients (group 1: n = 37; group 2: n = 37) completed the 1-year follow-up schedule and were included in the final analysis. Reduction of pain intensity measured by a numeric rating scale and increase in mouth opening distance (unassisted maximal, assisted maximal, and pain-free) was seen in both treatment groups. RESULTS: In group 1, pain intensity significantly decreased at 6 weeks and all subsequent time points compared with group 2. In terms of mouth opening distance, a significant improvement was observed in both groups during the course of treatment, but statistical significance was not seen between the 2 treatment groups. CONCLUSIONS: Early arthrocentesis supported by use of an occlusal splint is superior to use of an occlusal splint alone in the treatment of TMJ arthralgia. Arthrocentesis with occlusal splint support could be discussed as first-line treatment for arthralgia of the TMJ, which may co-occur with various painful and nonpainful conditions of TMJ disorders.

RESUMEN

OBJECTIVE: To evaluate the severity and prevalence of headache and facial pain/pressurere in the chronic rhinosinusitis (CRS) population. DATA SOURCES: CINAHL, PubMed, Scopus. REVIEW METHODS: The literature was searched from inception through June 2023 for English language articles documenting "headache" or "facial pain/pressure" and "chronic rhinosinusitis." Data collected included Lund-MacKay computed tomography score, Lund-Kennedy endoscopy score, sinonasal outcome test, and visual analog scale. Meta-analyses were performed on continuous measures (mean), proportions (%), and regression. RESULTS: A total of 69 studies were included with 8643 CRS patients and 703 control patients. The CRS group had a mean age of 44.1 (range: 16-82; 95% confidence interval [CI]: 40.3-48) and 86.1% [95% CI: 76.4-93.5] with nasal polyposis. The control group had a mean age of 39.2 (range: 17-88; 95% CI: 28.7-49.8). All CRS subgroups had significantly more severe headache and facial pain/pressure when compared to the control (P < .0001). Patients without polyps had significantly more severe facial pain/pressure and headache when compared to patients with polyps (P < .0001). Facial pain/pressure is a moderate problem or worse in 29.8% of polypoid patients versus 56.4% of nonpolypoid patients; Δ26.6% [95% CI: 0.7-50; P = .045]. CONCLUSIONS: Across all outcome metrics, CRS patients experience significantly more severe headache and facial pain/pressure when compared to a control population. Nonpolypoid patients experience significantly more severe facial pain/pressure and headache when compared to polypoid patients. The majority of nonpolypoid patients experience facial pain/pressure that is moderate in severity or worse.

RESUMEN

BACKGROUND AND PURPOSE: Otological symptoms (OS) are highly prevalent in individuals with temporomandibular disorders (TMD). Individuals with TMD and OS have more neck disability and decreased deep neck muscles endurance when compared to individuals without OS. However, no studies have evaluated whether OS is associated with lower Quality of Life (QoL) and worse levels of physical activity. This study aimed to evaluate the QoL and level of physical activity of individuals with TMD with and without OS. METHODS: In this cross-sectional study, 62 individuals with TMD were allocated into 2 groups: TMD with OS (n = 36) or TMD without OS (n = 26). Self-reported complaints of dizziness, vertigo, tinnitus, earache, ear fullness, or hypoacusis were considered as OS. QoL was assessed with the WHOQOL-Bref and physical activity with the IPAQ-SF. Independent t-test and chi-squared test were used for analysis between-groups. Effect sizes were reported using Cohen's d. A Pearson correlation was used to compare the number of OS and QoL scores. A significance level of p < 0.05% and 95% confidence intervals were considered statistically significant. RESULTS: The total generic scores for QoL were not different between-groups (p = 0.076), but individuals with TMD with OS had lower satisfaction (p = 0.015; d: 0.63) and physical domain (p = 0.015; d: 0.64) scores with a moderate effect size. In TMD with OS, 69.4% of individuals were irregularly active and 50% for the TMD without OS, with no statistical significance (p > 0.05). The number of OSs was inversely and weakly associated with the QoL total score. CONCLUSION: Individuals with TMD and OS are associated with worsened QoL (physical domain and satisfaction) when compared to individuals with TMD without OS. The higher the number of OS, the worse the QoL score. Individuals with TMD with and without OS had similar levels of physical activity, but a high prevalence of irregularly active and sedentary individuals within TMD diagnosed population was found.

RESUMEN

BACKGROUND: Headache and facial pain are common symptoms of chronic rhinosinusitis (CRS). However, given the numerous etiologies that can cause these symptoms, the impact of sinus surgery is not well characterized. METHODS: A systematic review was performed by searching the literature from inception through June 6, 2023. English-language articles reporting outcomes for facial pain/pressure or headache following endoscopic sinus surgery were selected for inclusion. Meta-analyses were performed using random and fixed effect models on continuous measures (mean), mean difference (Δ), and proportions (%). RESULTS: A total of 26 articles reporting on 2839 patients were selected for inclusion. The mean patient age was 44.0 ± 3.9 (range 16.0-84.0), with an average symptom duration of 5.3 ± 2.8 years. Among these patients, 56.5% (95% confidence interval [CI]: 52.3-60.6) were male and 77.0% (95% CI: 56.6-92.3) had nasal polyposis (NP). Patients with and without NP reported substantial reductions in both 22-item sino-nasal outcome test facial pain/pressure (with NP: -1.4 [95% CI: -1.6 to -1.2; relative reduction 59.1%]; without NP: -1.5 [95% CI: -1.9 to -1.1; relative reduction 60.9%]) and visual analogue scale (VAS) headache (with NP: -2.5 [95% CI: -2.8 to -2.1; relative reduction 67.2%]; without NP: -2.8 [95% CI: -4.7 to -1.0; relative reduction 42.7%]). Symptom reductions were greater in the without NP versus with NP group; VAS facial pain/pressure: Δ0.4 (95% CI: 0.2-0.6; p = 0.0006) and VAS headache: Δ0.4 (95% CI: 0.1-0.7; p = 0.02). CONCLUSIONS: Our findings suggest that CRS patients, regardless of polyp status, benefit from significant reductions in facial pain/pressure and headache following surgical therapy.

RESUMEN

BACKGROUND: The temporal tendon is a structure often compromised in patients suffering from temporomandibular disorders (TMD), yet its intraoral location makes a standardised assessment difficult. OBJECTIVES: To evaluate the variability and accuracy to target force of a newly designed intraoral extension for a palpometer device (Palpeter, Sunstar Suisse) when compared to manual palpation, in addition to clinically assessing the mechanical sensitivity and referred sensations of the temporal tendon in healthy individuals. METHODS: Experiment 1: 12 individuals were asked to target on a scale 0.5, 1 and 2 kg, for 2 and 5 s by using five different methods (Palpeter, Palpeter with three different extension shapes and manual palpation). Experiment 2: 10 healthy participants were recruited for a randomised double-blinded assessment by applying pressure of 0.5, 1 and 2 kg to the right temporal tendon with the three extensions and manual palpation. Participants rated the intensity of their sensation/pain on a 0-50-100 numeric rating scale (NRS), unpleasantness on a 0-100 NRS, and if present, they rated and drew the location of referred sensations. Repeated measures analysis of variance (ANOVA) was used in both experiments to compare differences between palpation methods. Tukey's HSD tests were used for the post hoc comparisons, and p values below .05 were considered significant. RESULTS: Experiment 1: The extensions showed no significant differences between them regarding reliability and accuracy for all forces and durations (p > .05). The manual method was significantly less reliable and accurate when compared to the other methods (p < .05). Experiment 2: There were no significant differences between the Palpeter extensions regarding pain intensity or unpleasantness NRS scores (p > .05), but all the extensions had significantly increased pain intensity and unpleasantness when compared to manual palpation (p < .05). Similarly, the frequency of referred sensations was similar between extensions but increased when compared to manual palpation. CONCLUSIONS: The new Palpeter extensions proved to be significantly more accurate and have lower test-retest variability than the manual method in a non-clinical setting. Clinically, they showed no significant differences in NRS scores for pain intensity nor unpleasantness, with no major differences in referred sensations, making any of the extensions suitable for clinical testing of the temporal tendon in future studies.

RESUMEN

BACKGROUND: Flupentixol and melitracen are being investigated for their potential effectiveness in managing persistent idiopathic facial pain (PIFP), based on their mechanisms of action as dopamine receptor antagonists and noradrenaline/serotonin reuptake inhibitors, respectively. The efficacy and safety of flupentixol and melitracen (FM) tablets in treating PIFP were retrospectively analyzed at our hospital. OBJECTIVES: The aim of this study is to determine the effectiveness and safety of FM tablets in treating PIFP. STUDY DESIGN: Retrospective unicentric cohort design. SETTING: An academic university hospital. METHODS: A retrospective analysis was conducted on a cohort comprising 128 patients with a definite diagnoses of PIFP who were treated with FM tablets (flupentixol 0.5 mg and melitracen 10 mg tablet, >= 4 tablets/d) from January 2022 through May 2023 at an academic university hospital. Baseline conditions were statistically described, and Numeric Rating Scale (NRS-11) scores of pain levels before and during treatment were collected. Pain relief rates were calculated. Differences in baseline characteristics between responsive and unresponsive patients were evaluated using statistical tests. Additionally, the side effects experienced during treatment were summarized. RESULTS: Among the included 128 patients, 105 (82.0%) patients achieved pain relief (pain NRS-11 score reduction rate >= 50%). The median treatment onset time was 3 (1-7) days. NRS-11 scores of responsive patients at week 2, week 4, week 8, and week 12 were significantly lower than the baseline NRS-11 scores (P < 0.001), regardless of their Hamilton Depression Rating Scale score. Pain duration was the only factor that related to responsiveness (Wilcoxon rank sum test, P < 0.001; logistic regression, P = 0.001). No serious side effects that could affect patients' lives were observed during the first week of treatments. LIMITATIONS: Due to its retrospective nature, this study is limited by its lack of a randomized control. The lack of data on nonresponders who did not achieve significant pain relief hinders assessing overall change and the placebo effects'. Patients previously treated with antidepressants were excluded, making it hard to determine if FM tablets were a better treatment for PIFP. Additionally, the small sample size in a single center may be influenced by chance variation in pain relief. CONCLUSIONS: FM tablets showed its potential in the management of PIFP with considerable efficacy and safety. Early administration of FM tablets after a PIFP diagnosis may result in a high possibility of pain relief.

RESUMEN

Objective: This study aimed to explore the prevalence, signs, and symptoms of different types of TMD (Temporomandibular joint disorders) disorders in Tunisian patients. Methods: A retrospective cross-sectional study was conducted using the clinical records of patients from the Department of Functional Exploration, Pain, and Orofacial Dysfunction of the Dental Clinic of Monastir. Results: TMD is associated with a female predominance, with a peak prevalence among those aged between 20 and 40 years. Pain and a limited range of motion were significantly more prevalent in women (p = 0.019 and p = 0.012, respectively). Clicking sounds were the most frequent joint noises (38.2 %). Crepitus was more prevalent among older adults (33 %). Of the different types of TMD, disk displacement with reduction was the most prevalent (n = 216, 39 %). Sleep bruxism was more prevalent than awake bruxism (20.7 % VS 9.5 %). Due to the heterogeneous TMD signs and symptoms, patients tend to seek medical attention from various specialties (e.g. neurology and otolaryngology). Conclusion: The prevalence of different types of TMD, and the different signs and symptoms varied depending on sociodemographic characteristics, such as sex, age and lifestyle. Diagnosis is challenging and TMD may be confused with other orofacial pain conditions.

RESUMEN

BACKGROUND: Temporomandibular disorders (TMD) is the leading cause of pain and disability among frequently occurring facial pain and the second leading cause of musculoskeletal conditions. AIM: We examined whether acupuncture could alleviate pain intensity in patients with temporomandibular disorders (TMD). DESIGN AND METHODS: Sixty participants with TMD were randomly assigned (ratio 1:1) to receive three acupuncture or sham acupuncture sessions weekly for 4 weeks. The primary outcome was the change in the mean weekly pain intensity from baseline to week 4. Secondary and exploratory outcomes included proportion of participants with ≥30% or ≥ 50% reduction in pain intensity, change in jaw opening and movement, graded chronic pain scale, jaw functional limitations scale-20-item, Depression, Anxiety and Stress Scales-21, Pittsburgh sleep quality index at week 4 and 8, and the pressure pain threshold and surface electromyography at week 4. RESULTS AND CONCLUSION: The acupuncture group showed significantly reduced pain intensity compared to the sham group at week 4 (-1.49, 95% confidence interval [CI]: -2.32 to -0.65; P < 0.001) and week 8 (-1.23, 95% CI: -2.11 to -0.54; P = 0.001). Acupuncture's effectiveness surpassed sham's at 4 weeks and lasted 8 weeks. Participants in the acupuncture group experienced significantly greater improvements in the 30% and 50% response rate, jaw opening and movement, GCPS, JFLS-20, DASS-21 and PSQI than those in the sham acupuncture group. There were no significant between-group differences in PPT and sEMG. In summary, acupuncture provided marked pain relief and improvement in physical and emotional function for patients with TMD compared with sham acupuncture.
