introduction: the use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   materials and methods: a prospective study of 80 ...

Introduction: Chronic otitis media (COM) has been broadly classified into mucosal and squamous subtypes. COM types are associated with erosion of the ossicular chain. The aim of the present study was to correlate the type of COM, the site of perforation/retraction, and the type of disease pathology with the pattern and degree of ossicular chain necrosis.   Materials and Methods: A prospecti...

OBJECTIVES This study was aimed to assess the relationship between the type of temporal bone area involved and conductive hearing loss. METHODS We enrolled 97 patients who visited the otolaryngology clinics of Seoul National University Hospital or Boramae Medical Center, Seoul Metropolitan Government-Seoul National University with temporal bone fracture between January 2004 and January 2014. ...

Introduction: The aim of this study was to evaluate the condition of the ossicular chain in patients requiring surgery for cholesteatoma.  Materials and Methods: In a retrospective analysis, the destruction of the individual and combined bony structures of the ear was described in 166 patients with cholesteatoma who went through surgery in our Otology Center between 2003 and 2009.  Results:...

BACKGROUND We aimed to evaluate the clinical and imaging presentations of Langerhans cell histiocytosis (LCH) in the pediatric temporal bone. METHODS This retrospective study included 27 pediatric cases with pathological confirmed LCH of the temporal bone. The clinical and imaging features of the cases were analyzed. The involvement of ossicular chain and otic capsule was also evaluated. RE...

OBJECTIVE To investigate and analyze the relationship between individual ossicular erosion and air-bone gap (ABG) among patients with cholesteatoma. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. SUBJECTS AND METHODS Data from all patients undergoing an initial surgery for cholesteatoma were retrospectively reviewed to evaluate the relationships between preopera...

OBJECTIVE To develop a staging system for congenital cholesteatoma in predicting the likelihood of residual disease. DESIGN Retrospective analysis of data from a case series, to identify predictors of residual disease. SETTING Tertiary care pediatric hospital. PARTICIPANTS Children undergoing surgical removal of congenital cholesteatoma. There were 156 patients, with 160 cholesteatomas; 4...

The aim of the study was to describe ossicle resorption in chronic otitis with cholesteatoma and correlate it with clinical parameters such as age, contralateral ear condition, tympanic membrane aspect, cholesteatoma pathogenesis and extension, associated lesions and hearing threshold. Preoperative clinical data were collected for 140 patients with chronic otitis with cholesteatoma, whose ossic...

OBJECTIVE To describe and quantify growth patterns of cholesteatomas within the middle ear using a scaled rating system that characterizes patterns of ossicular erosion. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Patients undergoing first-time surgery for primary and secondary acquired cholesteatomas. INTERVENTIONS Intraoperative assessments of os...
