Otoacoustic emissions in an aberrant internal carotid artery: a case report
1Department of Otolaryngology and Head and Neck Surgery, Chonnam National University Medical School, 8 Hackdong Donggu, 501-190 Gwangju, Korea.
Abstract:
A 52-year-old Korean woman who complained of impaired hearing and tinnitus of the left ear was diagnosed with an aberrant internal carotid artery (ICA) in the middle ear using a temporal bone high resolution CT (HRCT) scan. Upon otoscopic examination, her left eardrum was found to be in contact with a mass in the middle ear cavity. Upon audiometric evaluation, a mild conductive hearing impairment was documented, and a discrepancy in the results of otoacoustic emissions (OAEs) was found for the left ear. This case report studies the aberrant ICA in the middle ear that revealed abnormal OAE findings.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
