Congenital ossicular chain malformation (COCM) is a congenital developmental disorder that impairs hearing function. It most commonly presents unilaterally, either as an isolated anomaly or in association with a variety of systemic syndromes; in severe cases, it may coexist with malformations of the auricle and external auditory canal....
Surgeons treating congenital ossicular chain malformations should note this consensus classification, but adoption should be weighed against existing systems; expert consensus (Level 5 evidence) warrants prospective validation before broad implementation.
A standardised classification and surgical framework for congenital ossicular malformations could reduce variability in surgical decision-making and improve comparability of outcomes across centres.
- 012026 expert consensus proposes a novel classification of congenital ossicular chain malformations.
- 02Classification is based on stapes footplate mobility and integrity of the ossicular suprastructure.
- 03Includes recommended surgical management strategies for each class.
- 04Provides a framework for prognostic evaluation of surgical outcomes.
