Transotic Approach for Resection of Expansile Endolymphatic Sac Tumor.

Endolymphatic sac tumors (ELSTs) are rare and indolent tumors that arise from the endolymphatic sac in the posterior petrous ridge. We present a video case report illustrating the use of a transotic approach for resection of an expansile ELST.  A 25-year-old male presented with a multiyear history of worsening left-sided hearing loss, vertigo, and headaches.

Comparing Outcomes and Billing Costs of Middle Cranial Fossa and Transmastoid Approaches for Otogenic Encephalocele and Cerebrospinal Fluid Leak Repair.

Objective: Comparison of outcomes and billing costs of patients treated at our institution using transmastoid (TM), middle cranial fossa (MCF), and combined approaches for repair of otogenic cerebrospinal fluid (CSF) leaks and encephaloceles.

Study Design: Retrospective cohort review.

Setting: Tertiary-care hospital.

Resection of Intracochlear Schwannomas With Immediate Cochlear Implantation.

Introduction: Intralabyrinthine schwannomas, including the intracochlear variety, are rare benign tumors. They can cause a number of symptoms and have the potential to grow to involve other critical structures of the inner ear and skull base. While surgical resection is feasible, there is typically permanent hearing dysfunction as a result of resection and subsequent fibrosis.

Transmastoid Repair of Otogenic Encephaloceles in Patients With Canal Wall Down Mastoidectomy.

Objective: Description of a series of cases in which otogenic encephaloceles in patients requiring canal wall down (CWD) mastoidectomies were repaired via a transmastoid approach.

Study Design: Case series.

Setting: Tertiary-care hospital.
