Ramdoo K, Dale OT, Herdman RC. Malleo-incudal osteoma: an unexpected finding during surgery for presumed otosclerosis. J Laryngol Otol. 2011;125(9):968-9.
OBJECTIVE
To report a rare case of a symptomatic malleo-incudal osteoma, and to highlight the difficulties in making the clinical diagnosis.

METHOD
Case report and literature review.

RESULTS
Malleo-incudal osteoma is a rare cause of unilateral conductive hearing loss. Its symptoms may mimic those of other otological causes of conductive hearing loss, such as otosclerosis.

CONCLUSION
This case report highlights the challenges involved in establishing a clinical diagnosis of malleo-incudal osteoma. It also emphasises the importance of assessing the mobility of the divided ossicular chain during a planned stapedectomy.
