High-resolution computed tomography analysis of the medial infratemporal fossa: a pilot study.

Background: The medial aspect of the infratemporal fossa (ITF) can be accessed endoscopically. Two important landmarks to help guide dissection in this area have previously been identified: the anterior border of the foramen ovale (AFO) and the "bony bridge" (BB), a consistent bridge of bone between the foramen ovale and spinosum. We conducted a pilot study using high-resolution computed tomography (HRCT) to measure the distances to these structures.

Molecular markers of micrometastasis in oral cavity carcinomas.

Objective: To examine the expression of candidate markers for micrometastasis.

Study Design: Cross-sectional analysis of subjects with oral cavity carcinomas who underwent sentinel lymph node biopsy (SLNB) and subsequent immunohistochemical (IHC) analysis.

Subjects And Methods: Two groups were identified based on SLNB status: negative SLNB (19/30) and positive SLNB (11/30).

Endoscopic transnasal study of the infratemporal fossa: a new orientation.

Introduction: The medial portion of the infratemporal fossa (ITF) is not infrequently involved in sinonasal and skull base pathologies. However, endoscopic view of the ITF remains unclear with lack of studies addressing this region from the endoscopic perspective.

Methods: Using an extended endoscopic approach, the pterygopalatine and infratemporal fossae were dissected in 10 sides of five adult cadaver heads.

Endoscopic reconstruction of large anterior skull base defects using acellular dermal allograft.

Background: Endoscopic repair of small- to medium-sized anterior skull base (ASB) defects using bone, cartilage, fascia, fibrin glue, lipolized dura, and, more recently, acellular dermal allograft have all been described with equal efficacy. The purpose of this study was to review our experience with the use of acellular dermis as the sole graft material in endoscopic reconstruction of large ASB defects.

Methods: A retrospective chart review of all patients who underwent endoscopic repair of ASB defects at the University of Miami between the years of 2001 and 2006 was conducted.

Conservation of residual acoustic hearing after cochlear implantation.

Objective: This study was designed to test the hypothesis that partial hearing conservation is attainable after cochlear implantation with a long perimodiolar electrode. Surgical strategies for hearing conservation during cochlear implantation are described.

Study Design: Prospective, single-subject, repeated-measures design.
