“…An ossified stapedius tendon can sometimes be visualised on a high-resolution CT scan. 6 In our case, a CT scan was not performed. We decided to perform an exploratory tympanotomy instead.…”

“…Stapedial tendon ossification can be diagnosed using preoperative CT and exploratory tympanotomy. On temporal bone CT, it can be diagnosed as a linear image from the pyramidal eminence to the stapes superstructure[ 7 ]. Based on these findings, it can be differentiated from otosclerosis[ 16 ].…”

“…According to the literature, it can be diagnosed by computed tomography (CT) and tympanotomy. In addition, it is easily mistaken for otosclerosis, and thus discrimination is essential[ 7 ]. In the case described herein, surgical division was performed after diagnosing stapedial tendon ossification through exploratory tympanotomy, but hearing recovery was insufficient.…”

BACKGROUND Stapedial tendon ossification is a rare disease, with only a few reports. The stapedial tendon originates from the apex of the pyramidal eminence and is attached to the neck of the stapes. In stapedial tendon ossification, the stapes is fixed, causing conductive hearing loss. In most cases, complete hearing restoration is achieved by dividing the stapedial tendon after exploratory tympanotomy. CASE SUMMARY A 28-year-old woman presented to our hospital with the major complaint of bilateral hearing loss that started during childhood. Exploratory tympanotomy was performed due to suspicion of otosclerosis or middle ear anomalies. We found bilateral conductive hearing loss due to stapedial tendon ossification with a middle ear anomaly during surgery. There have been several reports of complete recovery of hearing after resection of the stapedial tendon. However, in this case, recovery of hearing was insufficient, even with the division of the stapedial tendon. In the second surgery, the stapes anomaly and footplate fixation were confirmed, and hearing was completely recovered after stapedotomy. Therefore, we report this case with a review of the relevant literature. CONCLUSION This is the first case of stapedial tendon ossification and fixation of the footplate surgically diagnosed on both sides. With surgical treatment, successful results are expected.

“…2 Other common conditions resulting in stapes fixation should be considered in the differential diagnosis, including tympanosclerosis, fenestral otosclerosis, congenital stapes fixation, absence of the oval window, and a persistent stapedial artery. 3 The etiology of ossification of the stapedius tendon remains controversial. Hough indicated that the ossification of the stapedius tendon rarely resulted from congenital causes and that tympanosclerotic degeneration frequently induced complete immobility that resulted in stapes fixation.…”

“…2 Surgical treatment can be performed by the simple division of the ossified stapedius tendon, or by stapedotomy/stapedectomy in patients with associated fixation of the stapes footplate. 3 Congenital nonsyndromic ossicular anomalies are an uncommon cause of conductive hearing loss. Of these, stapes fixation caused by an ossified stapedius tendon with normal mobility of the footplate, although rare, should be included in the differential diagnosis of conductive hearing loss with a normal tympanic membrane.…”
