[Tendoplasty and its effectiveness in the rehabilitation of hearing loss in patients with otosclerosis].

The article briefly presents the physiology of the stapes muscle tendon (SMT), and features in its defeat. Its length was studied using high-resolution multispiral computed tomography of the temporal bones. We also studied the possibility of its restoration using the author's method of tendoplasty using metallized stapes prostheses. Tendoplasty with stapedoplasty was performed in 74 patients with otosclerosis (OS), and 48 patients had stapedoplasty without tendoplasty. As a result of research, the average length of the SMT was 2.38±0.02 mm, which explains the need to use a 3 mm long venous autograft for tendoplasty. The author's method of tendoplasty for stapedoplasty allows restoring the acoustic reflex in 54.1% of OS patients using artificial stapes prostheses. The preservation of the vascular bed in the thickness of the restored tendon can improve the trophy of the long incus process and reduce the risk of its dystrophic changes in the postoperative period. In addition, this fact confirms the importance of the stapes muscle in the acoustic reflex.
