ABSTRACT
The objective of the study is to improve the efficacy of hearing improving operations in otosclerosis and chronic suppurative otitis media (CSOM). Results. 210 patients were examined in the premises of the Chair of Otorhinolaryngology of Mechnikov North-Western State Medical University at the period of 2015 through 2019. 95 patients were diagnosed with otosclerosis and 115 patients – with chronic suppurative otitis media. To identify the incidence of otolithiasis in the postsurgical period after hearing-improving operations, all patients with otosclerosis, as well as the patients with CSOM having the complaints of the vestibular system, were performed positional diagnostic Dix–Hallpike and Pagnini–McClure tests. Based on the results of positional tests in the postsurgical period after stapedoplasty, otolithiasis was diagnosed in 20 (21%) patients, after tympanoplasty – in 1 (0.8%) patient. To assess the effect of otolithiasis on the functional results of stapedoplasty, all the patients underwent an audiometric examination. The examination revealed that the occurrence of otolithiasis in the postsurgical period in patients with otosclerosis did not affect the functional results of stapedoplasty. It is seen from the significant improvement of hearing and the reduction of the bone-air interval, as well as the preservation of bone conduction at presurgical level. Otolithiasis after stapedoplasty is a common complication, but it is rarely observed after tympanoplasty.
