RESUMEN
RF devices have frequency, power and duration setting options, it is important to make sure that the device meets the targeted values at the head output. This study was made to evaluate the RF device output value accuracy and the effects of different frequencies on the tissue heat levels. RF was applied to invitro tissues obtained from surgical operations, and invivo tissues during operations. Heat differences and depth were measured by laser/IR thermometer and thermal infrared camera. First, the output frequency and power values provided by the device were approved. Then, three three heads (monopolar, bipolar and tripolar) with three different frequencies (1,7, 20 MHz) were used. Depth of heat increase was evaluated in millimeters. The results showed that temperature increase varied between 10°C and 30°C at different depths using different frequencies. Heating of the skin with a radiofrequency device in a therapeutic dose is possible if the appropriate frequency and adequate power values are applied. Because the therapeutic temperature is close to the complication limit, the practitioner should be an expert using the device, well-knowledgeable about the regional skin structure and thickness, as well as be able to properly adjust the application doses in order to get therapeutic results.

Background: Viability decreases at the distal parts with an increase in the length of flaps. In this study, we evaluated the effects of subcutaneously administered omentin on flap viability, where it is applied to distal one-third part of McFarlane flaps elevated from the rat's dorsal skin.Materials and methods: Twenty-four adult, female, Sprague-Dawley rats were used. Subjects were divided into three groups; group 1 is the control group, group 2 received omentin 1 week before flap elevation, and group 3 received omentin 2 d before and at the day of flap elevation. About 1 cc (300 nanogram/cc) omentin applied by subcutaneous injections to the distal one-third flap. Photos are taken daily for macroscopic evaluations. The 3-mm full thickness punch biopsies at the third day and 1-cm2 biopsies at the seventh day from the middle of the one-third distal third of the flaps were taken. Necrotic and viable areas were measured. Neutrophil counting, epidermis thickness, inflammation, edema, and vascular endothelial growth factor (VEGF) immune staining were evaluated using histopathological analyses. Endothelial Nitric Oxide Synthase (eNOS) expression was performed by ELISA.Results: Omentin increased the percentage of the viable areas of flaps, epidermal thickness, number of newly formed blood vessels, and eNOS expression levels. The results showed statistical significance.Conclusions: Omentin human increases the viable areas of flaps and may be used for enhancement of flap survival.

BACKGROUND: The prevalence of secretory otitis media is very high among the nonoperated cleft palate patients. METHODS: Ninety-one cleft palate operations were performed on late presented cases in Sudan, Africa. The surgeries were performed according to the Veau-Wardill-Kilner push-back technique. A laptop connected pen-type endoscopic camera was used to evaluate the tympanic membrane and address middle ear disease in all patients simultaneously. The procedure was performed after removing wax from the external auditory canal. A small incision was made with a myringotomy knife through the layers of the tympanic membrane if any sign of fluid collection was observed, after which the middle ear effusion was evacuated and the ventilation tube was inserted. RESULTS: This procedure was undertaken in 182 ears; 41 ears (22.5%) were healthy, 19 ears (10.5%) had chronic perforations, 122 ears (67%) underwent myringotomy procedures, and 54 (44.2%) were treated by inserting a ventilation tube. Despite the challenging work environment, standard monitoring facilities were available and all operations were completed with no early complications. CONCLUSION: The pen-type camera instead of an operating microscope was a tremendous contribution, as it was easy to handle and contributed to the good outcomes. The use of this technique is strongly recommended in surgical camps. LEVEL OF EVIDENCE: III.

The objectives of this study are to assess the velopharyngeal dimensions using cephalometric variables of the nasopharynx and oropharynx as well as to compare the Le Fort I osteotomy technique to Zisser's anterior maxillary osteotomy technique based on patients' outcomes within early and late postoperative follow-ups. 15 patients with severe maxillary deficiency treated with Le Fort I osteotomy and maxillary segmental osteotomy were assessed. Preoperative, early postoperative, and late postoperative follow-up lateral cephalograms, patient histories, and operative reports are reviewed with a focus on defined cephalometric landmarks for assessing velopharyngeal space dimension and maxillary movement (measured for three different tracing points). A significant change was found between preoperative and postoperative lateral cephalometric measurements regarding the distance between the posterior nasal spine and the posterior pharyngeal wall in Le Fort I osteotomy cases. However, no significant difference was found between preoperative and postoperative measurements in maxillary segmental osteotomy cases regarding the same measurements. The velopharyngeal area calculated for the Le Fort I osteotomy group showed a significant difference between the preoperative and postoperative measurements. Le Fort I osteotomy for advancement of upper jaw increases velopharyngeal space. On the other hand, Zisser's anterior maxillary segmental osteotomy does not alter the dimension of the velopharyngeal space significantly.

BACKGROUND: A series of previously described but rarely used variations of the pedicled, extended or vertical rectus abdominis musculocutaneous flap (Extended RAM, VRAM) were reviewed. METHODS: Skin paddle dimensions, ranged 8 to 28 cm in width and 10 to 35 cm in length, were used in five consecutive patients. Four flaps were placed deep to the inguinal ligament to repair the thigh as proximal to the knee region; the remaining one flap was passed transabdominally to cover the defect of the lumbar region. RESULTS: No flaps necrosis were seen and in one case wound healing problems required minimal operative intervention. Successful transfer of the VRAM and extended RAM with low rate of complication for the thigh and lumbar region defects were demonstrated to be safe and reasonable options of flap reconstruction. DISCUSSION: The flaps had the advantages of being robust and well-vascularized, easy and fast to harvest, and not requiring microsurgery experience.

With its perineural invasion capacity, periorbital squamous cell carcinoma (SCC) may easily invade orbital structures. When SCC invades the orbital musculature or the orbit itself, orbital exenteration, one of the most disfiguring operations on the face, is required. We reviewed elderly patients with periorbitally localized SCC requiring orbital exenteration to evaluate reconstructive options and survival. A chart review of patients' records was conducted to identify all patients older than 65 years with periorbital malignancy requiring orbital exenteration from 2006 to 2011. A total of 9 patients who met the criteria were included in the study. The mean age at surgery was 77 ± 6.7 years, and the mean defect size was 74.2 cm2. All patients had a similar history of late presentation to a doctor because of hesitation to undergo surgery. The temporoparietal fascia flap, galeal flap, free gracilis flap, and free vastus lateralis musculocutaneous flap were the treatment options for reconstruction of the defects. All patients died during follow-up, and the mean survival was 15.7 months (range, 6-36 months). Only 2 of them had relapse before the death. Our small series suggest that elderly patients with periorbital SCC requiring orbital exenteration may not have enough survival to relapse because of the death from different causes without relapse or any sign of spreading cancer. Also, prolonged surgery with free flap reconstruction may increase the risk of postoperative intensive care unit requirement. Because local flaps may work very well for reconstructing the orbital exenteration defects, free flap option should be kept for selected cases.

BACKGROUND: Enlarged breasts are associated with many physical and psychological symptoms. It is important to use objective criteria in documenting physical changes of a patient's body due to enlarged breasts and the benefits of surgery. This preliminary study aimed to determine whether the reduction mammaplasty procedure changes the angles of cervical lordosis, thoracic kyphosis, and lumbar lordosis. METHODS: The study population consisted of 22 patients who underwent breast reduction surgery. All the patients had lateral cervicothoracolumbar radiographs taken preoperatively and at least 2 months postoperatively. Cervical lordosis, thoracic kyphosis, and lumbar lordosis angles, as well as sagittal balance, were examined. The body mass index (BMI), breast tissue volume, and excised tissue amount of each patient were recorded. RESULTS: All the patients had increased cervical lordosis and thoracic kyphosis angles preoperatively, and the angles were significantly decreased postoperatively. Of the 22 patients, 7 had decreased and 8 had increased lumbar lordosis angles. All the lordosis angles showed significant improvement at the last examination. Seven patients had disturbed sagittal balance preoperatively, and all had normal sagittal balance postoperatively. Preoperative total breast tissue volume was positively correlated with the differences in cervical lordosis angles, BMI, preoperative cervical lordosis angles, and cervical lordosis angles. CONCLUSION: Hypertrophic breasts are not only a cosmetic but also a functional problem complicated by pathologic conditions in the vertebral column such as increased cervical lordosis, thoracic kyphosis, and increased or decreased lumbar lordosis. Breast reduction may improve these pathologic angles. Reducing the nonphysiologic weight of enlarged breasts located anterior to the main axis of the body may correct pathologic angulation and disturbed sagittal balance of the vertebral column.

As the usage of cell phones is markedly increasing worldwide, accidental injuries and even lethal damages caused by cellular phone explosions have been reported lately. Although, cell phone charger explosion related scalding and tissue loss is extremely rare, they generally cause severe damage to tissues and cause severe complications, ending up in hospitalization. We are presenting a case of 9-year old female patient who was admitted to our emergency service due to a phone charger explosion that resulted in a lower extremity tissue defect.
RESUMEN
This study aimed to evaluate the influence of type II diabetes mellitus (DM) on the postoperative outcomes of mini-open carpal tunnel syndrome (CTS) surgery. A total of 99 hands in 74 patients were included in the study. Of these, 36 patients (54 hands) had type II DM (Group A), and 38 patients (45 hands) had idiopathic CTS (Group B). Mini-open carpal tunnel release surgery was performed on all the hands. The night pain, weakness, paraesthesia, numbness complaints were significantly improved in both groups after surgery. However, thenar atrophy was improved significantly only in group A. Night pain, weakness, paraesthesia, numbness, and pillar pain were significantly worse in Group A than in Group B on postoperative examination. Postoperatively, Tinnel and Phalen tests were positive in 32 hands in Group A and 6 hands in Group B. Persistence of symptoms in diabetic patients was found to be more prevalent compared to non-diabetic controls after mini-open carpal tunnel release.

BACKGROUND: Neurofibromatosis may present with different skin lesions. Disfiguring lesions on the face might be challenging for the surgeon or clinician to correct and may have adverse effects on patients' social lives, especially in young women. OBJECTIVE: To present the dermabrasion technique combined with serial excisions of a deeper accompanying lesion to treat superficial facial lesions in a young neurofibromatosis patient. METHODS: Dermabrasion was applied to superficial lesions on the face, and staged excision was applied to the deeper lesion located on the forehead. RESULTS: We obtained high patient satisfaction with the result. The deep lesion was excised totally, and superficial lesions were decreased with dermabrasion. CONCLUSION: Dermabrasion may become a good alternative in cases of neurofibromatosis with superficial facial lesions.

BACKGROUND: We investigated the effect of a combination of pregabalin and dexamethasone, when used as part of a multimodal analgesic regimen, on pain control after rhinoplasty operations. METHODS: Sixty patients were enrolled in this study. They were randomly assigned into three groups: Group C (placebo + placebo), Group P (pregabalin + placebo), and Group PD (pregabalin + dexamethasone). Patients received either pregabalin 300 mg orally 1 h before surgery, dexamethasone 8 mg intravenously during induction, or placebo according to their allocation. Postoperative pain was treated with intravenous patient-controlled analgesia (tramadol, 20-mg bolus dose, 45-min lockout time). The numeric rating scale (NRS), side effects, and consumption of tramadol, pethidine, and ondansetron were assessed. RESULTS: The median NRS scores at 0, 1, and 6 h after surgery were significantly higher in Group C than in Group PD (p < 0.001 for all). The 24-h consumption of tramadol and pethidine was significantly reduced in Groups P and PD compared to Group C (p < 0.01 and p < 0.01). The total tramadol consumption was decreased by 54.5 % in Group P and 81.9 % in Group PD compared to Group C (p < 0.001 for both). The incidence of nausea was higher in Group C than in Groups P and PD between the postoperative 0-2 and 0-24-h periods (p < 0.05 for both). The frequency of blurred vision was significantly higher in Groups P and PD than in Group C within the 0-24-h period (p < 0.05 for both). CONCLUSION: We found that the addition of a single dose of pregabalin and dexamethasone to multimodal analgesia in rhinoplasty surgeries provided efficient analgesia and thus decreased opioid consumption.

Two patients, aged 18 and 28 years, with maxillofacial trauma due to motor vehicle accident, were operated upon by a team of plastic surgeons. In this report we aimed to present our experience with submental intubation procedure in these cases, in which orotracheal or nasotracheal intubation was impossible due to panfacial fracture.
RESUMEN
Neonatal compartment syndrome is a rare condition mainly involving the upper extremity associated with necrotic lesions. It is often initially misdiagnosed because the skin lesions mimic several other conditions of the newborn. Early diagnosis and timely intervention are of paramount importance to achieve the best outcome. In the present case, we describe a newborn with forearm compartment syndrome owing to being stuck in the birth canal.

Although microsurgery has rapid expanded, problems related to microarterial anastomosis continue. Cigarette smoking is one of the major risks for anastomosis by increasing platelet adhesion, and its effects on endothelial cells. Aim of this article is to study the negative effects of cigarettes on microarterial anastomosis line, and to investigate the protective effects of recombinant human erythropoietin (rHuEPO).Ninety-six Sprague-Dawley male rats were divided into 3 groups: group 1 was the control. Rats in groups 2 and 3 were exposed to cigarette smoke starting 21 days prior to surgery for 3 times a day. In group 3, additional 150 IU/kg rHuEPO was given via subcutaneously every 48 hours after microvascular anastomosis, femoral arterial samples, and blood samples were taken for assessment at 1st, 3rd, 5th, and 7th day. Intimae/media ratios were calculated for morphologic analyses.On morphologic analysis of femoral arteries there were statistically significant differences for all 3 groups at 1st, 3rd, 5th, and 7th days (P < 0, 05). The group that made differences was group 2, according to one-way analysis of variance within 3 groups in all days.Smoking decreases endothelial cells healing and causes more thromboses. rHuEPO can prevent these negative effects of smoking.

BACKGROUND: The reconstruction of soft tissue defects of the elbow area (including antecubital fossa and peri-olecranon area) should be performed with the most appropriate soft tissue and functional rehabilitation immediately. METHODS: Ten patients were included in this study. One had a brachial artery defect, another had postburn axillary contracture deformity, and a third had an ulnar bone body fracture in addition to their soft tissue defects, while the remaining seven had only soft tissue defect. Patients underwent surgical closure either by local arm fasciocutaneous flap (1), radial forearm flap (1), multiple Z-plasty (1), pedicled latissimus dorsi muscle flap (3), or with the antecubital fasciocutaneous island flap (4). RESULTS: The follow-up was 9 months to 4 years (mean: 19 months). All the flaps achieved wound closure without losing the range of motion at the elbow joint. CONCLUSION: Surgical closure of the antecubital fossa and peri-olecranon areas can be a challenge for plastic surgeons since this area includes numerous neuro-vascular bundles and a functional joint. Therefore, we describe herein an algorithm for the treatment of defects in these areas from the inspiration in our clinical experience and a literature review. Our algorithm will help to decide the most appropriate choice among all of the surgical options available.

Hairy polyps of the head and neck are rare congenital tumors that may cause upper aerodigestive tract impairment in newborn. Although cleft palate is a common congenital anomaly, hairy polyp with cleft palate is extremely rare in the newborn. We aimed to present the planning of reconstruction in a patient who has an incomplete cleft palate and defect due to hairy polyp excision on soft palate in this report. A 9-month-old child was admitted to our clinic due to cleft palate. In the clinical examination, incomplete cleft palate plus a defect on the posterior side of the left soft palate was observed. On the history, the patient had been operated urgently at the newborn period for a hairy polyp localized on the left soft palate which had obstructed the airway. Wardill-Kilner-Veau technique was modified for the reconstruction of the defect on the soft palate and incomplete cleft palate. No complication was seen on postoperative period. The speech ability was evaluated on the late postoperative controls after 3 years and adequate speech intelligibility was obtained. A case of hairy polyp of nasopharynx with incomplete cleft palate in a neonate and its reconstruction techniques are discussed. The etiology of hairy polyp, hamartoma, teratoma, dermoid cyst and epignathus, their nomenclature, histopathology, clinical features, and management in neonates are also discussed briefly.

Parry-Romberg syndrome (PRS) is an uncommon disorder and characterized by a slowly, an acquired progressive atrophy involving skin, soft tissue, cartilage, and bony structures. Accompanying atrophies of the other parts of the body are rarely reported. The aim of this study is to report a case that had contralateral lower extremity atrophy with PRS, and to review the related etiologic features, physiopathology, and mechanism. The patient who admitted for his facial atrophy also had atrophy of his contralateral extremity. This extremity was also short in length when compared with other extremity. To obtain detailed information regarding the severity of involvement routine laboratory investigations including antinuclear antibody (ANA), magnetic resonance imagine (MRI) of the craniofacial region and lower extremities, MR angiography of the lower extremities and brain, 3-dimension computed tomography (CT) scan of the craniofacial region were performed. Normal or negative laboratory findings included results of blood count, renal and hepatic function biochemical tests, rheumatoid factor, C-reactive protein, anti-dsDNA antibody except ANA that were positive. His lower extremity and brain MR angiography were normal. In the 3-dimensional cranial CT, there was no abnormality or defect in the bony structures. His brain MRI showed no pathologic changes, and his facial MRI demonstrated noteworthy atrophy to the sternocleidomastoid, masseter, pterygoid muscles, and subcutaneus soft tissues on the right side of the face. Additionally, MR investigation of his lower extremities revealed decreased volume in muscles and bony structures of the effected extremity compared with the other extremity, but pathologic evidence of fatty degeneration associated with muscle atrophy was not demonstrated. The patient had isolated contralateral lower extremity involvement combined with hemifacial atrophy (without affecting any other part of the body). Although more accepted theory is the sympathic nervous system dysfunction, autoimmunity may play a roll in the etiology of our case as ANA abnormality was found in multiple tests.
