The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the...

AIMS Both children and adults are subject to similar types of injuries but fractures of facial bones in children are relatively uncommon. The aim of this study was to evaluate the epidemiology of facial bone fractures among children of <12 years, their management and outcome in an Indian city. MATERIAL AND METHODS This retrospective study included children of <12 years of age with facial bone...

Facial bone fractures account for a sizeable proportion of the cases treated by maxillo-facial and oral surgery units in South Africa. In this study, clinical records of all facial bone fractures among black, coloured, Asian, and ie/. '<• patients treated in the Department o f Maxilla-Facial am Oral Surgery in the Johannesburg group o f teaching hospitals over a six-month period, were recorded ...

OBJECTIVES The purpose of this cone beam computed tomography (CBCT) study was to describe the facial bone changes around single implants for immediate placement and provisionalization following tooth extraction in the maxillary anterior. MATERIAL AND METHODS The data between 2008 and 2013 were collected retrospectively. Superimposed facio-palatal cross-sectional CBCT images for the implants w...

In 1997, Lambert and colleagues demonstrated that the absence of sinus fluid on head CT essentially excludes a fracture involving the sinus walls. Our purpose is to reevaluate this association utilizing the current standard of imaging technology. With improved image resolution, we aim to reassess whether the sensitivity and specificity of the "clear sinus sign" are improved or worsened. Further...

aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

443 Pneumomediastinum is a rare complication that occurs after facial bone contouring surgery. However, it is considered as a life-threatening complication, and it is difficult to prevent pneumomediastinum as it occurs due to unknown or unexpected reasons. There are two suggestive causes of pneumomediastinum that occurs in association with facial bone contouring surgery. First, pneumomediastinu...

Facial nerve palsy due to temporal bone metastasis of hepatocellular carcinoma (HCC) has rarely been reported. We experienced a rare case of temporal bone metastasis of HCC that initially presented as facial nerve palsy and was diagnosed by surgical biopsy. This patient also discovered for the first time that he had chronic hepatitis B and C infections due to this facial nerve palsy. Radiation ...
