Relationship of petrous temporal bone pneumatization to the eustachian tube lumen.

Objectives/hypothesis: Objectives were to determine the incidence of petrous apex pneumatization and to define the relationship between a pneumatized petrous temporal bone and the eustachian tube lumen.

Study Design: Retrospective study with institutional review board approval including only adult patients.

Methods: One hundred head computed tomography (ct) scans and 204 petrous temporal bone CT scans performed at a tertiary teaching hospital were reviewed.

Sporadic Burkitt's lymphoma of the head and neck in the pediatric population.
