In the absence of middle ear effusion or tympanic membrane pathology, stapes fixation secondary to otosclerosis is often considered the most probable diagnosis. However, although otosclerosis is traditionally regarded as a bilateral disease, clinical presentation may be unilateral due to asymmetric disease progression or subclinical contralateral involvement. Other etiologies, including congenital ossicular anomalies, ossicular discontinuity, tympanosclerosis without tympanic membrane involvement, or oval window abnormalities, may mimic otosclerosis both clinically and audiologically. Consequently, exploratory tympanotomy remains the gold standard for definitive diagnosis, allowing direct assessment of ossicular chain mobility and confirmation of stapes fixation. Correlating preoperative clinical suspicion with intraoperative findings is therefore essential to better define the true causes of unilateral conductive hearing loss with an intact tympanic membrane.",[64],"Conductive Hearing Loss, Unilateral",[66,67,68,69,70],"Otoscelrosis","Exploration Tympanotomy","stapedectomy","tympanic membrane","conductive hearing loss","2026-02-19",{"date":73,"type":74},"2026-02-24","ACTUAL",{"date":76,"type":74},"2026-01-01",{"date":78,"type":58},"2026-05",{"name":5,"class":6},1]
