BACKGROUND AND PURPOSE: Petrous apex cephaloceles (PACs) are uncommon
lesions that are usually incidental but may be symptomatic. We reviewed MR and CT studies …

OBJECTIVE: The goals of this investigation were to perform a detailed analysis of petroclival
microanatomic features, to investigate the course of the abducens nerve in the petroclival …

OBJECTIVE: We investigated the membranous architecture of the abducens nerve at the
petroclival region and describe the characteristics of this area in cadaveric specimen and …

The goal of this study was to determine the membranous protection of the abducens nerve in
the petroclival region. The petroclival portion of the abducens nerve was studied in ten …

Approaching the petrous apex can be complex and fraught with danger. Identifying
favorable pathology and gaining access endoscopically is a direct, fast, and minimally …

The diagnosis of petrous apex lesions includes a variety of lesions, and one of the most
uncommon is a mucocele of the petrous apex (1). The first report in 1979 detailed the …

Mucocele is a benign, encapsulated lesion, lined by epithelium and filled with mucus. Found
mostly in the frontal and ethmoid sinus, sinonasal mucoceles cause several symptoms …

frecuentes en esta localización. Caracterizar las distintas lesiones que pueden manifestarse …

The pinna (auricle), external auditory canal (EAC), and the tympanic membrane form the
external ear apparatus (Figure 13.1). The surface anatomy of all these structures can be …

The Meckel's cave is a dural recess in the posteromedial portion of the middle cranial fossa
and is the location of the trigeminal ganglion. Disease processes that affect the Meckel's …
