Introduction. Chronic suppurative otitis media is a chronic inflammation of the mucoperiosteum of the middle ear, which is characterized by the presence of persistent otorrhea, perforation of the tympanic membrane and hearing loss. According to WHO data, about 3%-4.7% of the population suffers from chronic suppurative otitis media, of which 60% (200 million) suffer from moderate and severe hearing impairment. Material and methods. A randomized clinical trial during the years 2020-2022 was realized. I group consisted of 10 patients with chronic suppurative otitis media (2 patients- status after radical surgery) and 8 patients in remission after tympanoplasty type I. Group II - control group was made of 10 patients (2 after radical surgery with auditory prosthesis) and 8 patients with chronic suppurative otitis media in remission, stable form (conservative treatment). All the patients had transmission hypoacusis and mixed moderate and severe form. Results. The first 2 patients after radical surgery underwent BoneBridge type bone implantation surgery, of which in 2 patients the FMT was inserted on the dura mater (middle cerebral fossa), in 4 patients it was inserted in the mastoid region. In 4 patients after type I tympanoplasty, a VibrantSoundbridge type middle ear implant was performed with the placement of the coupler on the short apophysis of the incuss. Conclusion. In all 10 cases there was an improvement in hearing with a difference of over 20dB-35dB. Surgical rehabilitation of auditory function in patients with transmission and mixed hearing loss caused by chronic suppurative otitis media represents a real challenge for otologists.
