Abstract
- Congenital anomalies of ossicle in the middle ear are rare and could appear in various forms. The most common congenital isolated ossicular anomalies are stapes fixation and incudostapedial discontinuity, with isolated congenital stapes fixation representing about one third of ossicular malformations. We present a rare case of monocrural anomaly of unilateral stapes in a 36-year-old woman with nonprogressive conductive hearing loss. During explotympanotomy, the lateral half of the suprastructure of anomalous stapes was removed and sculptured total ossicular replacement prosthesis was fitted between the long process of incus and remained stapes. Postoperative pure tone audiogram showed a significant decrease in air-bone gap. We report this case with a review of literature.
