INTRODUCTION First branchial cleft anomalies manifest with duplication of the external auditory canal. CASE REPORT This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a...

Introduction. Congenital cholesteatoma is a pearly white mass that rarely originates from the mastoid process. Case Report. A 21-year-old male patient presented to our department with severe right mastoid pain and postauricular fluctuant swelling for 23 days. There was no preceding history of ear complaints and examination showed a normal right ear drum. Emergency exploration of the mastoid pro...

Cholesteatoma has been known to be associated with multiple complications either extracranially or intracranially. Among the extracranial complications, mastoiditis and mastoid abscess are the most common. Bezold’s abscess formation with cholesteatoma is a rare occurrence but when present can lead to sinister sequalae if not properly managed. The treatment of cholesteatoma is mainly by surgical...

A retrospective study was conducted on a cohort of 15 patients who underwent surgery because cholesteatoma or abscess was suspected. All patients had MR imaging prior to surgery with diffusion-weighted images (DWI) from which the apparent diffusion coefficient (ADC) value was calculated. Using this technique, we were able to determine 3 distinct ADC value ranges corresponding to the 3 groups of...

Cholesteatoma is a collection of keratinous debris and stratified squamous epithelium. It is trapped in the middle ear and can lead to bony erosion. The disease is treated surgically often followed by a second-look procedure to check for residual tissue or recurrence. Cholesteatoma has specific signal-intensity characteristics on magnetic resonance imaging with very high signal intensity on dif...

A rare case of congenital cholesteatoma as a cause of acute labyrinthitis is presented in the report. 14-years old boy was operated due to labyrinthitis caused by a huge cholesteatoma discovered behind intact tympanic membrane. On the first examination the symptoms indicated lack of right inner ear function, so unfortunately the referral was to late and the patient resulted in the dead ear. The...

Transcanal endoscopic ear surgery (TEES) is being increasingly used in chronic ear disease for cholesteatoma removal and middle ear reconstruction, reducing the need for a postauricular incision and mastoidectomy. However, TEES is a challenging technique even for the most experienced otologist, requiring one-handed dissection using angled instrumentation. We have therefore developed a high-fide...

INTRODUCTION Chronic cholesteatoma otitis media, apart from destruction of bones and possibility of otogenous complications, is characterized by possibility of recurrence of the disease after non radical treatment or presence of risk factors. AIM This paper intends to analyze changes typical for cholesteatoma, observed during otosurgery including the results of bacteriological investigations....

Introduction: In developing countries, chronic otitis media (COM) and cholesteatoma are relatively prevalent.  Within the field of otology, COM surgery remains one of the most common surgical treatments. Most recent studies evaluating the potential prognostic factors in COM surgery have addressed graft success rate and types of middle ear and mastoid pathology. There has been much controversy a...

Hypothesis: We hypothesized that an anomalous change of Notch signaling might be involved in the pathophysiology cholesteatoma. Background: The pathway regulates integrated growth and differentiation control keratinocytes. Its involvement cholesteatoma proliferation has not been elucidated. Methods: obtained external auditory canal (EAC) skin samples from patients with middle ear who underwent ...
