Embryological development of middle ear ossicles is a complex process and congenital abnormalities and variations are very rare. Therefore, adding new knowledge to this conditions is highly important. This case report describes a rare case of variation consisting of bilateral pneumatization in the incus body in a patient with left-sided mixed-type hearing loss. These incus variations were detected incidentally during the examination performed for an otological problem. This paper discusses the possible embryological mechanism for the occurrence of this rare incus variation and its significance.

Orta kulak kemikçiklerinin embriyolojik gelişimi karmaşık bir süreçtir ve konjenital anormallikler ve varyasyonlar çok nadirdir. Dolayısıyla bu durumda yeni bilgilerin eklenmesi son derece önemlidir. Bu olgu sunumu, sol tarafta mikst tip işitme kaybı olan bir hastada inkus gövdesinde bilateral yarık oluşumundan oluşan nadir bir varyasyon olgusunu anlatmaktadır. Bu inkus varyasyonu otolojik problem için yapılan muayenede tesadüfen tespit edildi. Bu makale, bu nadir inkus varyasyonunun oluşumu için olası embriyolojik mekanizmayı ve önemini tartışmaktadır.
