Hearing preservation in acoustic neuroma resection: Analysis of petrous bone measurement and intraoperative application
BACKGROUND There is an increased risk for labyrinthine injury for the resection of acoustic neuromas (AN) on the suboccipital, retrosigmoid approach. Prognostic factors should be analyzed for the postoperative hearing function. METHODS We examined 51 patients with ANs using preoperative intact hearing function. Audiological data were obtained by pure tone audiogram (PTA) and speech audiogram....
متن کاملComparing Ancient DNA Preservation in Petrous Bone and Tooth Cementum
Large-scale genomic analyses of ancient human populations have become feasible partly due to refined sampling methods. The inner part of petrous bones and the cementum layer in teeth roots are currently recognized as the best substrates for such research. We present a comparative analysis of DNA preservation in these two substrates obtained from the same human skulls, across a range of differen...
متن کامل[Dilemma in surgical treatment of petrous cholesteatoma].
Surgical treatment of petrous cholesteatoma that involves the petrous pyramid and extends beyond the internal auditory canal is often difficult because of the site and extent of the cholesteatoma. Various problems pertaining to the operation are discussed from our experience with fourteen patients who underwent surgery in our hospital. When accompanied with otorrhea, the middle ear was eradicat...
متن کاملGiant Congenital Cholesteatoma of the Petrous Bone Personal Experience and Literature Review
Congenital cholesteatoma of the petrous bone, though originating in childhood, has often a delayed diagnosis due to its poor symptoms and can grow achieving great extension. When asymptomatic or pauci-symptomatic, the diagnosis is incidental and purely radiological. Leaving the lesion untreated implies an inexorable progression leading to extensive erosion of the petrous bone and cranial nerves...
متن کاملSurgical Management of Cholesteatoma Growing Medially into the Petrous part of the Temporal Bone
In this article we describe the surgical management of petrous bone cholesteatoma, a rare form of an epidermoid cyst growing medially into the petrous part of the temporal bone. In our series of 5 patients, high resolution Computerized Tomography (CT) played an essential role in the diagnosis of this pathological entity. CT was also important in planning for the surgical access to this intricat...
