A tiny retraction of the pars flaccida may conceal an attic cholesteatoma.

Objective: The purpose of this study was to evaluate the possibility of attic cholesteatomas concealed within a tiny retraction of the pars flaccida (classification of Tos and Poulsen type I or II attic retraction) in patients with an intact pars tensa of the tympanic membrane.

Methods: The clinical records of patients with a tiny retraction of the pars flaccida and an intact pars tensa of the tympanic membrane who presented to the ear clinic of a tertiary care medical center for the first time between March 2012 and February 2015 were retrospectively reviewed. All patients who had an abnormal pars flaccida of the tympanic membrane were recommended to undergo temporal bone computed tomography (CT) scans.

A Case of Medullary Infarction Presented Initial Symptoms Similar to Meniere's Disease.

Fluctuating hearing loss and vertigo are the typical presentations of Meniere's disease. However, it is unusual that fluctuating hearing loss and vertigo are caused by vertebral artery occlusion or cerebral infarction. Here, we described the case of a 54-year-old male patient with hypertension and diabetes mellitus who presented with fluctuating hearing loss in his left ear and severe whirling-type dizziness without associated neurological signs or symptoms.

Postoperative Mastoid Aeration Following Canal Wall Up Mastoidectomy according to Preoperative Middle Ear Disease: Analysis of Temporal Bone Computed Tomography Scans.

Background And Objectives: The aim of our study was to evaluate postoperative mastoid aeration according to the preoperative middle ear disease and investigate the factors affecting it.

Subjects And Methods: We retrospectively reviewed the high-resolution computed tomography (CT) scans of temporal bones that were taken 1 year after surgery. The postoperative mastoid aeration was evaluated according to the preoperative diagnosis, and classified into three groups: grade 1 (complete mastoid aeration), an air-filled epitympanum and mastoid cavity; grade 2 (partial mastoid aeration), an air-filled epitympanum and partially aerated mastoid cavity; and grade 3 (absence of mastoid aeration), no air space in the mastoid cavity.
