Complication rate of transtemporal hydroxyapatite cement cranioplasties: a case series review of 76 cranioplasties.
The objective of this study was to evaluate the complication rate of transtemporal cranioplasties using hydroxyapatite cement (HAC) for repair. ⋯ This retrospective review provides the largest series to date evaluating the incidence of infection in HAC cranioplasties. Despite having a much larger series, our complication rate is the lowest published rate of HAC cranioplasty explantation, and the incidence of superficial wound infections reported here is consistent with the published data for neurosurgical and neurotologic procedures.

To elucidate indications and outcomes with the transjugular craniotomy for resection of jugular foramen tumors with intracranial extension. The transjugular approach is a lateral craniotomy conducted through a partial petrosectomy traversing the jugular fossa combined with resection of the sigmoid sinus and jugular bulb, which often have been occluded by disease. ⋯ Most patients with jugular foramen tumors with intracranial extension can be managed with a single-stage transjugular craniotomy. Facial nerve mobilization or ear canal closure is usually not required, permitting conservation of facial function and hearing, when present preoperatively.

The genesis, morphology, and growth characteristics of vestibular schwannomas are determined by genetic alterations which vary gene transcript expression and this transcript expression can be qualitatively and quantitatively evaluated using the SAGE technique. By use of such technique, gene products with tumorigenic potential may be identified, providing insight and targets for future study. ⋯ These data demonstrate that microSAGE is a useful technique to study vestibular schwannoma gene expression. Future studies will include building more comprehensive libraries and comparing libraries from various vestibular schwannoma phenotypes to identify useful diagnostic or prognostic markers, and targets for therapeutic intervention.

To determine the natural history of permanent gentamicin vestibulotoxicity. ⋯ Gentamicin can cause permanent vestibular and auditory ototoxicity. There is no safe dose of gentamicin. Serum gentamicin levels are of no value in predicting the onset, occurrence, or severity of vestibulotoxicity or cochleotoxicity. Termination of gentamicin on appearance of signs or symptoms of ototoxicity may reduce the incidence of permanent vestibular ototoxicity. When possible, other antibiotics should be administered.

To evaluate surgical outcomes for the treatment of posterior fossa meningiomas at the House Ear Clinic from 1987 to 2001. We review our current treatment algorithm and present our postoperative outcomes with attention to facial and auditory neural preservation. ⋯ Advances in microsurgical techniques have greatly changed our management of patients with posterior fossa meningiomas. These changes have reduced postoperative morbidity. Specifically, use of the anterior and posterior petrosal approaches has facilitated facial and auditory neural preservation while not compromising the extent of tumor excision.
