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...

Some patients with autoimmune disease will experience otologic symptoms, such as pain and hearing loss. We present a patient ANCA-associated vasculitis who required surgery for suspicious mastoid lesion associated her disease.

Cochlear implantation in canal wall down mastoid (CWD) cavities is fraught with the issue of how best to manage the mastoid cavity. Decision points include whether the external auditory meatus should be overclosed, whether the implantation should be staged, or even if the eustachian tube should be plugged. Given these options, we sought to describe our experience of cochlear implantation in CWD...

BACKGROUND AND AIM Dorsal augmentation of the nose is needed after trauma, rhinoplasty or for ethnic reasons. Alloplastic or autogenous materials may be used. In this paper, postauricular mastoid fascia was used for dorsal nasal augmentation. METHODS This study included ten patients who underwent dorsal nasal augmentation. Fascia over mastoid area was taken in all cases and was fixed with Ste...

Results: Cephaloauricular angle measurements of patients before the operation ranged from 46 to 57-degree. The median cephaloauricular angle was 51-degree. The recorded upper pole-to-mastoid distance ranged from 15 to 27 mm. The median upper pole-to-mastoid distance was 20 mm. After the operation, the median upper pole-to-mastoid distance was 12 mm. The postoperative median cephaloauricular ang...

Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which ...
