THE problem of healing in mastoid cavities is still with us despite many advances in knowledge and operative techniques. The optimal cavity should be small, completely lined by nourishing epithelium and accessible through an adequate meatus. The problem is as old as otology itself but it has received renewed impetus and urgency from the belated recognition that however successful tympanoplasty ...

A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Tempor...

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...

Introduction The objectives of mastoidectomy in cholesteatoma are a disease-free and dry ear, the prevention of recurrent disease, and the maintenance of hearing or the possibility to reconstruct an affected hearing mechanism. Canal wall down mastoidectomy has been traditionally used to achieve those goals with greater or lesser degrees of success. However, canal wall down is an aggressive appr...

OBJECTIVES To describe middle ear ventilation route blockage, relieved during middle ear endoscopic surgery, and to analyze its association with mastoid hypopneumatization/sclerotization. STUDY DESIGN Prospective case series with intraoperative analyses, and with a case-control computed tomographic scan comparison. METHODS Intraoperative findings during endoscopic middle ear surgery are des...

OBJECTIVE Our study emphasizes the relationship between the temporal bone structures and the mastoid portion of the facial nerve. MATERIAL AND METHODS Thirty-two temporal bones taken from adult cadavers of both sexes subjected to tympanoplastic procedure were used to make reference measures of the mastoid portion of the facial nerve. Appropriate instruments were used for measurement and stati...

Sound pressure levels (SPLs) were measured in the external auditory canals (EACs) of 16 subjects with normal hearing and normal middle ear immittance. SPLs were the result of bone-conduction (BC) stimulation at 500, 1000, 2000, and 4000 Hz, with the oscillator placed either on the forehead or on the mastoid process. At 1000, 2000, and 4000 Hz, significantly higher SPLs were measured when the he...

OBJECTIVE Evaluating intracranial complications of otitis media. DESIGN An Evaluative study of 106 cases of intracranial complications secondary to otitis media. INTERVENTION Diagnosis is based on history, clinical exam (general, systemic and ENT), investigations hemogram, X-ray mastoid CT scan brain and mastoid. TREATMENT Medical management:IV Higher Antibiotics.Surgery for complicating ...

Introduction: Chronic otitis media is chronic inflammation of middle ear cleft followed by permanent abnormality tympanic membrane. As mastoid a part temporal bone in close relation to ear; its pneumatization plays an important role pathogenesis and prognosis media.
 Aims: To study the pattern unilateral relationship with contralateral mastoid, diseased side membrane ossicular status.&#x0D...

The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...
