The object of the fenestration operation is to overcome the obstruction offered to the transmission of sound-actuated waves by the fixation of the footplate of the stapes in the oval window by osteosclerotic bone. This is achieved by providing an opening in the wall of the bony labyrinth that will allow free movement of labyrinthine fluids in response to transmitted sound waves (Cawthorne, 1952...

We present a 65 year old male, who developed giant Cholesteatoma with intracranial extension, multiple cranial nerve palsies, lateral sinus thrombosis with obliteration and post aural fistula. The Patient had foul smelling discharge from right ear since childhood. He complained of headache and LMN type of facial paralysis (right) since 6 months. Patient underwent Right Modified Radical Mastoide...

A complication of otitis media is defined as a spread of infection beyond the pneumatized area of the temporal bone and the associated mucosa. Complications can be classified as intra temporal or intra cranial, which includes extradural abscess, brain abscess, subdural abscess, sigmoid sinus thrombophlebitis, otic hydrocephalus, and meningitis. Since the introduction of antibiotics, intra crani...

OBJECTIVE The aim of this study was to evaluate the initial and longer term success of closing the air-bone gap (ABG) to 20 dB in ossiculoplasty with canal wall down mastoidectomy. METHODS This study was conducted at a private otologic practice. Patients included those who underwent ossiculoplasty from 1989 to 1996 with canal wall down mastoidectomy, whether primary or revision (33 from a tot...

OBJECTIVES/HYPOTHESIS The future development of integrated automatic assessment in temporal bone virtual surgical simulators calls for validation against currently established assessment tools. This study aimed to explore the relationship between mastoidectomy final-product performance assessment in virtual simulation and traditional dissection training. STUDY DESIGN Prospective trial with bl...

OBJECTIVE This study was designed to investigate the long-term results using the technique of canal wall up mastoidectomy and reconstruction of the posterior canal wall using bone pâté and auricular cartilage in the treatment of chronic otitis media with cholesteatoma. MATERIALS AND METHODS A retrospective review was performed on 42 patients who underwent canal wall up mastoidectomy and poste...

OBJECTIVES To evaluate the efficacy of combined antistaphylococcal and antipseudomonal preoperative antibiotics for preventing surgical site infections following tympanoplasty and mastoidectomy with contaminated cholesteatoma. STUDY DESIGN Retrospective chart review. METHODS Medical records of patients who underwent tympanoplasty ± mastoidectomy for cholesteatoma were reviewed. Only cases c...

Mastoidectomy is one of the most common surgical procedures relating to the petrous bone. In this paper we describe our preliminary results in the realization of a virtual reality mastoidectomy simulator. Our system is designed to work on patient-specific volumetric object models directly derived from 3D CT and MRI images. The paper summarizes the detailed task analysis performed in order to de...

OBJECTIVE To review the clinical charts of 45 paediatric patients treated for acute otomastoiditis at the ORL Department of the University of Brescia (Italy) between January 1994 and March 2005 and to discuss the diagnostic workup and the outcome of treatment. METHODS Twenty-six males and 19 females were admitted with acute mastoiditis and subperiosteal abscess. Thirteen of them (28.9%) prese...

OBJECTIVE To evaluate the therapeutic effects in terms of disease clearance and hearing improvement of canal wall up mastoidectomy in combination with Type I tympanoplasty in otitis media. METHODS A total of 78 patients (81 ears) with otitis media were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty. The postoperative tympanic membrane morphology, average of pu...
