Introduction: Surgical treatment of condylar neck fractures requires an extraoral approach when, due to the degree of difficulty of the fracture, an intraoral approach or an endoscopically supported treatment is not possible. In contrast to the cosmetically more favorable oral approach, extraoral approaches offer a better overview of the operating field and thus an easier fracture repositioning and osteosynthetic treatment. In 2007, Marti et al. described a minimal pre- and retroauricular incision with no extension to the hair-bearing skin and which aimed to improve the parotidectomy approach...

Introduction: To avoid injury of the descending palatine artery during Le Fort I osteotomy, I believe that it is important to measure the right distance between the piriform rim and the most anterior point of the descending palatine canal on the CT images and to insert the chisel to the correct distance. To achieve this maneuver easily, a novel chisel with depth markings is developed. Material and methods: The osteotome is based on a general thin osteotome of 6 mm width...

Introduction: Various methods are deployed by an oral and maxillofacial surgeon to control the osteotomised/ fractured bony segments intraoperatively till the time a stable fixation in the desired position is achieved. Few of these include the use of bone holding crocodile forceps, towel clips, reduction forceps, wires, digital control (Thota and Mitchell in Br J Orthod 26(4):325, 1999). In our technique, we present the use of an IMF screw to manipulate bony segments intraoperatively...

Introduction: The use of the Carroll-Girard screw in the management of zygomatic complex fractures has been well documented. The instrument provides an excellent degree of control over the movements of the disrupted zygomatic bone. Often mentioned in textbooks and literature, they are not routinely available for the Indian maxillofacial surgeon. This often prevents the regular use of this approach. Material and methods: We have used the 2.5-mm orthopaedic bone tap that is very commonly available and routinely used in orthopaedic surgeries for reduction of the malar bone...

Introduction: Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos...

Introduction: Among all head and neck tumors, only 0.5% occur in the parapharyngeal space and 80% are benign tumors. Surgery is the cornerstone of treatment. The deep location of this space and surrounding structures has given rise to a large number of surgical approaches for resection of parapharyngeal neoplasms. Our experience using the submandibular transcervical approach on 14 patients who had surgery upfront for treatment of these lesions is described. Material and methods: This is a retrospective, descriptive case-series analysis of patients with parapharyngeal space tumors treated from January 2009 to July 2016, in whom carotid body tumors were excluded...

Background: The prophylactic extraction of third molars is a common practice in dental offices, but divergent opinions are found in the literature regarding the indication of this procedure. The aim of the present study was to determine the prevalence of pathological changes associated with the pericoronal tissue of asymptomatic impacted third molars that could justify prophylactic extraction. Materials and Methods: A cross-sectional observational study was conducted in which 109 pericoronal tissues with no radiographic evidence of pathology were histopathologically analyzed...

Background: Photographic soft-tissue norms of Iranian race are not reported previously, nor are they compared with other ethnicities. Besides, sex dimorphism is assessed in only very few studies on soft-tissue profile. The aim of this study was to assess the soft-tissue measurements of Iranians with good occlusion and the existing sex dimorphism and to compare the Iranian norms with other ethnicities. Materials and Methods: Twelve anthropometric variables were measured by a dentist in 100 Iranian subjects with good occlusions...

Purpose: Traditionally, the "Halstead block" has been widely used to provide anesthesia in mandibular teeth. Two other techniques, the Gow Gates mandibular nerve block and the Akinosi Vazirani closed-mouth mandibular nerve block, are reliable alternatives to the conventional inferior alveolar nerve block. The purpose of this study is to evaluate the onset of anesthesia, anesthetic success and incidence of positive aspiration during administration of local anesthetic solution using the Halstead, Vazirani Akinosi and Gow Gates techniques...
