Conductive Hearing Loss - Not Always Otosclerosis (2022 AMW)
2022 AAO-HNSF Annual Meeting & OTO Experience
A negative middle ear exploration for otosclerosis is disappointing for the patient and surgeon alike. Perhaps worse is finding a pathology that the team is not prepared to manage or for which surgery is contraindicated. Accordingly, this panel presentation, sponsored by the Otology and Neurotology Education Committee, will equip clinicians to successfully distinguish and manage the range of “can’t miss” diagnoses that mimic otosclerosis. Experienced panelists will present clinical cases united by a chief complaint of conductive hearing loss. Cases will include acquired and congenital ossicular pathologies (e.g., ossicular fixation, x-linked stapes gusher), third window lesions (e.g., canal dehiscence and enlarged vestibular aqueduct), and pseudo-conductive hearing loss. Panelists will discuss, debate, and illustrate key elements of the history, physical exam, and audiometric test battery that point to specific diagnostic possibilities. They will detail their approaches to imaging acquisition and interpretation. Evidence-based surgical and non-surgical management strategies for conductive hearing loss will be presented for each case, along with expected outcomes and potential complications. The panel will conclude with a discussion of a systematic approach to middle ear exploration when the diagnosis remains ambiguous.
