The mastoid cavity after ''debridement" becomes one of the main causes of failure in the follow-up of tympanoplasty when left unobliterated. Various trials have been made to seek an effective method of filling up the cavity. We conducted a study on mastoidplasty using autogenous bonemarrow and free skingraft and found the results were satisfactory. 15 patients were observed clinically, histolog...

A single-stage fitting of a bone-anchored hearing aid (BAHA) implant and abutment with mastoid obliteration both obviates the need for two separate procedures and utilises the BAHA soft tissue reduction in the mastoid obliteration. Such a procedure has good outcomes in terms of osseointegration and achieving a dry ear. We present a 6-patient case series report highlighting the technique of comb...

Introduction: This study was designed to evaluate the usefulness of mastoid cavity obliteration with combined bone pâté and Palva flap in the prevention of problematic mastoid cavities after canal wall down mastoidectomy.   Materials and Methods: In a prospective longitudinal study with a mean follow-up of 28 months conducted between 2008–2012, a series of 56 ears in 48 patients with chronic ot...

BACKGROUND A mastoid cavity resulting from a canal wall down mastoidectomy can result in major morbidity for patients due to chronic otorrhea and infection, difficulty with hearing aids and vertigo with temperature changes. Mastoid obliteration with reconstruction of the bony external ear canal recreates the normal anatomy to avoid such morbidity. Few have the studied the quality of life benefi...

The aim of this study is to evaluate the use of our nano-HA/PCL composite 3D scaffolds as graft materials for mastoid cavity obliteration in an animal model. Nano-HA particles were synthesized by chemical precipitation technique and mixed them with PCL solution to make composite paste. 3D scaffolds were fabricated by a paste extruding deposition process. The nano-HA/PCL 3D scaffolds showed good...

OBJECTIVES Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of β-tricalcium phosphate and polyphosphate (β-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS Twenty patients with chronic otitis media underwent mas...

OBJECTIVE To assess middle ear aeration after total mastoid obliteration using bone pate and hydroxyapatite performed at the second stage of intact-canal-wall (ICW) tympanoplasty. STUDY DESIGN Retrospective study. SETTING Tertiary referral hospital. PATIENTS Forty-two ears with cholesteatoma underwent the obliteration. Computed tomography (CT) scan 1 week before the second-stage operation...

INTRODUCTION A chronic discharging ear has been a challenge for the otologists for centuries. The mainstay of treatment for cholesteatoma is surgery and the surgical treatment of choice is modified radical mastoidectomy. The open mastoidectomy technique has been the mainstay of management of chronic ear disease; however this type of surgery is not without its problem. It results in the formatio...
