Squamous cell cancer of the temporal bone: a review of the literature.

Background And Aims: Squamous cell carcinoma (SCC) of the temporal bone is a rare malignancy accounting for only 0.2% of head and neck cancers. There is currently no clear consensus on staging or common approach to management.

Feasibility of a synthetic temporal bone for training in mastoidectomy: face, content, and concurrent validity.

Objective: To investigate the face, content, and concurrent validity of the synthetic Pettigrew temporal bone (PTB) for mastoidectomy training as compared with cadaveric temporal bone (CTB).

Study Design: A prospective evaluation study.

Methods: Participants were invited to perform a step-by-step modified radical mastoidectomy using both bones and complete a 22-item, 5-point Likert scale questionnaire.

Three-year ear, nose, and throat cross-sectional analysis of audiometric protocols for magnetic resonance imaging screening of acoustic tumors.

Objectives: (1) Evaluate audiometric protocols and recommend protocols with best sensitivity and specificity for magnetic resonance imaging (MRI) screening of acoustic tumors; (2) determine clinical risks (false negative) of missing acoustic tumors and potential wastes in screening (false positive) nonacoustic tumors or radiologically "normal" cases; and (3) identify the decibel difference and range of frequencies compared by the best-performing protocols.

Study Design: Cross-sectional study with chart review.

Setting: Ear, nose, and throat (ENT); audiology; and radiology departments in a tertiary-care hospital.

Teflon-induced granuloma: a source of false positive positron emission tomography and computerized tomography interpretation.

Patients diagnosed with malignancy often undergo combined positron emission tomography (PET) and computerized tomography (CT) to investigate possible metastases. This report presents a case in which, in the investigation of suspected pulmonary malignancy, combined PET and CT images suggested a malignant lesion at the level of the vocal fold. Biopsy of the lesion, however, confirmed the clinical diagnosis of a Teflon granuloma.
