RESUMEN

BACKGROUND: Osteoarthritis (OA) is the most common form of arthritis of the temporomandibular joint (TMJ), and can often lead to severe pain in the orofacial region. Management options for TMJ OA include reassurance, occlusal appliances, physical therapy, medication in addition to several surgical modalities. OBJECTIVES: To investigate the effects of different surgical and non-surgical therapeutic options for the management of TMJ OA in adult patients. SEARCH METHODS: We searched the following databases: the Cochrane Oral Health Group Trials Register (to 26 September 2011); CENTRAL (The Cochrane Library 2011, Issue 3); MEDLINE via OVID (1950 to 26 September 2011); EMBASE via OVID (1980 to 26 September 2011); and PEDro (1929 to 26 September 2011). There were no language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any form of non-surgical or surgical therapy for TMJ OA in adults over the age of 18 with clinical and/or radiological diagnosis of TMJ OA according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) guideline or compatible criteria.Primary outcomes considered were pain/tenderness/discomfort in the TMJs or jaw muscles, self assessed range of mandibular movement and TMJ sounds. Secondary outcomes included the measurement of quality of life or patient satisfaction evaluated with a validated questionnaire, morphological changes of the TMJs assessed by imaging, TMJ sounds assessed by auscultation and any adverse effects. DATA COLLECTION AND ANALYSIS: Two review authors screened and extracted information and data from, and independently assessed the risk of bias in the included trials. MAIN RESULTS: Although three RCTs were included in this review, pooling of data in a meta-analysis was not possible due to wide clinical diversity between the studies. The reports indicate a not dissimilar degree of effectiveness with intra-articular injections consisting of either sodium hyaluronate or corticosteroid preparations, and an equivalent pain reduction with diclofenac sodium as compared with occlusal splints. Glucosamine appeared to be just as effective as ibuprofen for the management of TMJ OA. AUTHORS' CONCLUSIONS: In view of the paucity of high level evidence for the effectiveness of interventions for the management of TMJ OA, small parallel group RCTs which include participants with a clear diagnosis of TMJ OA should be encouraged and especially studies evaluating some of the possible surgical interventions.

RESUMEN

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare entity that usually occurs as 0.5-3 cm pink to brown nodules in the skin surface and subcutaneous tissues of the head & neck. Here we report an unusual occurrence in size and appearance of ALHE in the tissues of the cheek of an adult Asian male.

RESUMEN

BACKGROUND: This is an update of a Cochrane Review first published in The Cochrane Library in Issue 1, 2010.Tonsillectomy is the surgical removal of lymphoid tissue, the palatine tonsil, which is located at the back of the throat. It is still commonly performed for patients who have recurrent bouts of acute tonsillitis. Although tonsillectomy is considered a fairly minor procedure, pain and bleeding are two of the most common complications; either may delay recovery and can on occasion lead to hospital readmission. Postoperative tonsillectomy medication should provide an adequate reduction in morbidity while minimising side effects, therefore topical agents would seem to be an ideal, safe option. A number of mouthwashes and topical sprays are available which offer pain relief or can help to reduce bleeding in the immediate postoperative period. OBJECTIVES: To assess the effects of oral rinses, mouthwashes and sprays in improving recovery following tonsillectomy. SEARCH STRATEGY: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 22 April 2011. SELECTION CRITERIA: We included randomised controlled trials in which mouthwashes, used pre- and postoperatively, have been compared with placebo. DATA COLLECTION AND ANALYSIS: Two review authors selected trials for inclusion, assessed the risk of bias and extracted data independently. MAIN RESULTS: We included six trials (528 participants; 397 children and 131 adults). The period of follow up ranged from 24 hours to two weeks. Few of the trials provided reliable data for the pre-specified primary outcomes and none for the secondary outcomes. Lidocaine spray appeared to be more effective than saline spray at reducing the severity of pain but only until the third postoperative day. A small number of participants experienced a burning or stinging sensation with benzydamine spray but not sufficient to discontinue usage. AUTHORS' CONCLUSIONS: The risk of bias was high in most of the included trials and poor reporting quality and inadequate data did not permit comprehensive and reliable conclusions to be made. Future trials should be well-constructed and pay more attention to the methods used to assess outcomes, the timing of the assessments, and the quality of reporting and subsequent analysis of the data.

RESUMEN

BACKGROUND: Benign masseter muscle hypertrophy is an uncommon clinical phenomenon of uncertain aetiology which is characterised by a soft swelling near the angle of the mandible. The swelling may on occasion be associated with facial pain and can be prominent enough to be considered cosmetically disfiguring. Varying degrees of success have been reported for some of the treatment options for masseter hypertrophy, which range from simple pharmacotherapy to more invasive surgical reduction. Injection of botulinum toxin type A into the masseter muscle is generally considered a less invasive modality and has been advocated for cosmetic sculpting of the lower face. Botulinum toxin type A is a powerful neurotoxin which is produced by the anaerobic organism Clostridium botulinum and when injected into a muscle causes interference with the neurotransmitter mechanism producing selective paralysis and subsequent atrophy of the muscle. OBJECTIVES: To assess the effects of botulinum toxin type A in the management of benign bilateral masseter hypertrophy. SEARCH STRATEGY: We searched the following databases in August 2008: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, issue 3); MEDLINE (via PubMed) (1950 to August 2008); EMBASE (via embase.com) (1980 to August 2008); and LILACS via BIREME. We searched two bibliographic databases of regional journals which may be expected to contain relevant trials (IndMED and Iranmedex) using free text terms appropriate for this review. SELECTION CRITERIA: Randomised controlled clinical trials (RCTs) and controlled clinical trials (CCTs) comparing intra-masseteric injections of botulinum toxin versus placebo administered for cosmetic facial sculpting in individuals of any age with bilateral benign masseter hypertrophy, which had been self-evaluated and confirmed by clinical and radiological examination. We excluded participants with unilateral or compensatory contralateral masseter hypertrophy resulting from head and neck radiotherapy. DATA COLLECTION AND ANALYSIS: Two review authors conducted screening of studies in duplicate and independently, and although no eligible trials were identified, the two authors had planned to extract data independently and assess trial quality using standard Cochrane Collaboration methodologies. MAIN RESULTS: We retrieved 167 references to studies, none of which matched the inclusion criteria for this review and all of which were excluded. AUTHORS' CONCLUSIONS: We were unable to identify any randomised controlled trials on the efficacy of intra-masseteric injections of botulinum toxin for people with bilateral benign masseter hypertrophy. The absence of high level evidence for the effectiveness of this intervention emphasises the need for well-designed, adequately powered, randomised controlled clinical trials (RCTs) and controlled clinical trials (CCTs).
