Large, complicated iatrogenic EAC cholesteatomas usually require surgical management, with the selected technique generally based on the extent of disease and the surgeon's preference.

Iatrogenic skull base cholesteatoma

August 18, 2018  |  Renuka K. Reddy, BS; Kristen A. Echanique, BS; Robert W. Jyung, MD

Iatrogenic skull base cholesteatomais a rare consequence of canal-wall-up mastoidectomy, and it can be difficult to visualize otoscopically, contributing to a delayed diagnosis.

Hemifacial spasm secondary to middle ear cholesteatoma

June 28, 2018  |  Maheep Sohal, MD; Nicholas Karter, MD; Marc Eisen, MD, PhD

Abstract

Hemifacial spasm is a peripheral myoclonus of the VIIth cranial nerve that is characterized by paroxysmal contraction of the muscles of facial expression. It exists in both primary and secondary forms. In rare cases, hemifacial spasm is caused by middle ear pathology. We...

Mastoid obliteration, scutum plasty, and ossiculoplasty without staging after canal-wall-up attico-mastoidectomy in adults

June 28, 2018  |  Shao-Cheng Liu, MD; Shyi-Gen Chen, MD; Chih-Hung Wang, MD; Bor-Rong Huang, MD

Abstract

In a retrospective chart review, we evaluated the surgical and hearing results of a single-stage procedure consisting of a canal-wall-up attico-mastoidectomy, mastoid cavity obliteration, scutum plasty, and ossiculoplasty. A total of 77 patients treated between March 2003 and...

Clinical characteristics and follow-up of patients with external ear canal cholesteatoma treated conservatively

July 18, 2016  |  Erdal Sakalli, MD; Deniz Kaya, MD; Cengiz Celikyurt, MD; Selcuk Cem Erdurak, MD

Abstract

We conducted a retrospective study to evaluate the clinical properties and follow-up of patients with external ear canal cholesteatoma (EECC) who were treated conservatively. Our study group was made up of 15 patients-6 men and 9 women, aged 21 to 82 years (mean: 48). In...

Cholesteatoma and coexisting findings diagnosed incidentally on MRI

June 14, 2016  |  Gahl Greenberg, MD; Ana Eyal, MD; Arkadi Yakirevitch, MD; Michael Wolf, MD; Lela Migirov, MD

Abstract

The explosive growth in the use of diffusion-weighted magnetic resonance imaging (MRI) in the pre- and postoperative evaluations of patients with cholesteatoma has led to a concomitant increase in the number of incidental findings in this population. We describe our...

Cholesteatoma should be differentiated from other conditions with similar otoscopic findings, such as myringosclerosis.

Is there a relationship between myeloperoxidase activity and conductive hearing loss in chronic otitis media complicated by cholesteatoma?

April 28, 2015  |  Ozlem Celebi Erdivanli, MD; Arif Sanli, MD

Abstract

We conducted a prospective, controlled study of patients with chronic otitis media and cholesteatoma (1) to examine the expression of myeloperoxidase (MPO) using immunohistochemical staining techniques and (2) to investigate the relationship between MPO activity and the degree...

February 2, 2015  |  Francesco Fiorino, MD; Francesca B. Pizzini, MD, PhD; Barbara Mattellini, MD; Franco Barbieri, MD

Abstract

A 40-year-old man presented with conductive hearing loss and pressure- and sound-related vestibular symptoms. Computed tomography and diffusion-weighted magnetic resonance imaging revealed the presence of a cholesteatoma involving the vestibular labyrinth. The patient underwent...
