RESUMO
Central muco epidermoid carcinomas (CMC) are rare tumours, representing about 2 to 3% of all mucoepidermoid carcinomas. Usually affecting the mandible, they appear as uni- or multilocular radiolucent lesions. We report a case of CMC in a 52-year-old Middle Eastern woman who presented with pain, limitation of jaw movement and tingling sensation of the tongue, related to a radiolucent lesion in the angle of the mandible. The lesion was first detected but not diagnosed in another hospital three years earlier. We describe the progression of the lesion over the past three years and describe the clinical, radiographic, histopathological, and surgical aspects of the case.

The aim of this study was to investigate the effects of two commonly used flap designs (envelope and triangular) used for the removal of mandibular third molars (M3) on postoperative morbidity. 19 patients with bilateral symmetrically impacted mandibular M3 were studied using a split mouth design. Swelling, pain and trismus measures were recorded on days 2, 7 and 14; periodontal indices were recorded on days 7 and 14, one final measure of probing depth on the distal aspect of the mandibular second molar (M2) was taken at the last follow up appointment. Data were analysed using the χ(2) test, the Mann-Whitney U-test and Pearson's correlations. The mean age of the patients was 21.4 ± 2.3 years (± SD). Facial swelling and the reduction in mouth opening were significantly greater in the early postoperative period (P<0.05) with pyramidal flap designs. There was no significant difference in pain scores, plaque accumulation and bleeding on probing indices between the two flap designs (P>0.05). Probing depth was significantly greater with envelope flaps in the early postoperative period (P<0.005). In conclusion, flap design in mandibular M3 surgery has an effect on postoperative recovery.
