Outcome of Stapes Surgery in Otosclerotic Patients With Tinnitus Using Tinnitogram

Outcome of Stapes Surgery in Otosclerotic Patients With Tinnitus

This study will be conducted on patients with otosclerosis attending Assiut University Hospital and undergo stapedectomy operation Evaluation of each patient will conducted preoperatively and 3 month postoperatively Patient will undergo tinnitogram and tinnitus handicap questionnaire before and after the operation to measure improvement in hearing and tinnitus

Otosclerosis is an abnormal bone remodeling in the middle ear The normal dense endochondral layer of the bony otic capsule in the labyrinth is replaced by irregularly laid spongy bone leading to the fixation of the stapes.

• Clinical otosclerosis is more prevalent in females than in males, giving rise to the hypothesis that sex hormones may contribute to the development of disease
• The age of onset is variable, although hearing loss typically begins in the third decade, with a range from first decade to the sixth decade.

In most cases, hearing loss is bilateral (70-85%) and is usually asymmetrical, developing initially in one ear before progressing to the other.

Positive family history of otosclerosis has been previously reported in between 30-70% of cases.

The diagnosis is usually made clinically by

• History
• Physical examination,
• Audiogram results(tinnitus handicap questionnaire arabic version, tinnnitogram ) most frequent presentation of patients with clinical otosclerosis is bilateral hearing loss and tinnitus Between 65 and 87% of patient with otosclerosis experience tinnitus. most of them has unilateral tinnitus 83.3% , while only 16.7% reported bilateral tinnitus.

patients with tinnitus often report that their tinnitus is associated with feelings of sadness, worry, frustration, and anger.

These feelings can lead to difficulties sleeping, relaxing, and concentrating and may negatively impact relationships at work and impair participation in social settings .

Tinnitogram :

Tinnitus pitch match : we will start at 1000 Hz and move up and down in frequency.

Tinnitus loudness match : patient threshold was determined at frequency of pitch matching, sound level will increase in small steps(1or 2 dB ) until patient repoted that specific tone will just equal in loudeness to his tinnitus Tinnitus handicap questionnaire arabic version

Exclusion Criteria:
