background: hearing loss due to chronic otitis media is common. the purpose of this study was to evaluate hearing before and after canal wall up, canal wall down mastoidectomy and tympanoplasty. methods: from 2004 to 2007, all patients with chronic otitis media who were admitted at the department of otolaryngology, babol medical university were studied. for 126 patients' canal wall up, can...

OBJECTIVES/HYPOTHESIS To evaluate the acoustic effect after canal wall-down tympanoplasty with sectioning of the tensor tympani muscle (TTM) tendon in patients with chronic otitis media. STUDY DESIGN Prospective, controlled clinical trial. METHODS From January 2010 to April 2014, 212 patients underwent canal wall-down tympanoplasty with ossicular chain reconstruction in one-stage surgery. F...

Aim: Aim of this study was to describe an effective technique for mastoid cavity obliteration and reconstruction attic region in canal wall down Tympano mastoidectomy for unsafe chronic otitis media and to review its efficacy in producing a dry, low maintenance, small mastoid cavity. Material and method: In this prospective study, 100 patients were selected who were undergoing procedures for ac...

Peristaltic contraction of the embryonic heart tube produces time- and spatial-varying wall shear stress (WSS) and pressure gradients (∇P) across the atrioventricular (AV) canal. Zebrafish (Danio rerio) are a genetically tractable system to investigate cardiac morphogenesis. The use of Tg(fli1a:EGFP) (y1) transgenic embryos allowed for delineation and two-dimensional reconstruction of the endoc...

We reviewed our series of surgeries for paediatric cholesteatoma to assess outcomes and functional results considering the extension of disease and surgical techniques. Between January 2003 and December 2009, 36 patients (range 6-14 years) were operated on for cholesteatoma. We considered the sites involved by the cholesteatoma (mastoid, antrum, attic, middle ear, Eustachian tube), surgical tec...

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...
