Abstract

Introduction
Otosclerosis is an autosomal-dominant, hereditary disease (25-40% penetrance) of the otic capsule, in which compact bone is remodeled to vascularized, spongy bone, causing stapes fixation and hearing loss (HL). Patients usually present in their 2nd – 4th decades of life, with gradual onset, slowly progressing bilateral, assymtrical HL. They may have hyperacusis Willisi, low monotonous speech, tinnitus and/or vertigo. Clinical findings are a negative Rinne, a falsely lateralized Weber’s tests, and normal otoscopy (or rarely, Schwartze sign). Pure tone audiometry (PTA) reveals gradual low to high frequencies conductive hearing loss (CHL), air–bone gap (ABG) widening, and Carhart’s notch at 2 KHz, with excellent speech discrimation score (SDS) and As type tympanogram. Surgical treatment remains gold-standard, however, malcrimping accounts for 85% of revision surgery.
Aim of the Work
The aim of this 6-month, randomized, prospective study was to compare hearing results between glass ionomer cement (GIC)– Intervened otosclerotic patients and non– GIC intervened ones during the crimping step of primary stapedotomy, at the Otorhinolaryngology Department in Alexandria Main University Hospital.
