OBJECTIVES To demonstrate that the regions of the infratemporal fossa and skull base at the level of the foramen ovale can be visualized endoscopically and that structures can be manipulated within these regions using endoscopic instruments. METHODS Cadaveric dissection of 3 human cadavers using an endoscopic optical dissector. In all, 6 endoscopic infratemporal fossa and skull base approache...

IMPORTANCE Congenital pyriform fossa sinus tracts predispose to neck masses and neck abscesses in pediatric and occasionally adult patients. Traditional management involves open excision with substantial potential morbidity. Endoscopic management allows an alternative, less morbid treatment approach. OBJECTIVE To evaluate the long-term effectiveness of endoscopic cauterization as definitive t...

BACKGROUND Chiari-like malformation (CM) and syringomyelia is a neurological disease complex with high prevalence in cavalier King Charles spaniels (CKCS). The natural progression of this disease with time has not been described. The objectives of this study were to i) determine if syringomyelia progresses with time ii) determine if features of craniocrebral morphology previously associated wit...

BACKGROUND Congenital cholesteatoma may be expected in abnormally developed ear, it may cause bony erosion of the middle ear cleft and extend to the infratemporal fossa. We present the first case of congenital cholesteatoma of the infratemporal fossa in a patient with congenital aural atresia that has been complicated with acute mastoiditis. CASE PRESENTATION A sixteen year old Egyptian male ...

Objective: To describe the possibility of rotation of the vermis as the cause of enlarged posterior fossa in the fetus. Methods: Eight women were referred to our ultrasound unit for evaluation of enlarged posterior fossa with suspected agenesis of the vermis on axial plane.
