    Introduction: The influence of the mechanics of the middle ear on the function of the inner ear has been studied for many years. Among surgeries performed in the middle-ear area, those restoring full functionality of the system transmitting sound inside the middle ear may be pointed out as those fully restoring the mechanical influence of the middle ear on the function of the inner ear. Aim: The aim of the performed analysis is to find the prognostic importance of measured pre-surgery values of bone conduction on the improvement of hearing in patients operated as a result of middle-ear disorders. Material and methods: The analysis included 271 patients hospitalised and operated on due to otosclerosis or perforation of the tympanic membrane between 2016 and 2019. Only patients who had not had a surgical operation within the middle ear prior to the study were included. An audiological assessment was performed with the use of pure tone thresholds audiometry. Results: A beneficial influence of the performed surgery on the improvement of bone conduction was observed in patients, in which the average threshold value of bone conduction measured before the surgery did not exceed 40 dB. In cases of the perceptive component of hearing impairment being higher than 40 dB, no statistically significant, beneficial influence of a performed stapedotomy or myringoplasty on the change of bone conduction thresholds was observed. Conclusions: The perception component of hearing impairment up to 40 dB indicates bone conduction improvement after surgical restoration of the influence of middle-ear mechanics on the inner ear in patients treated as a result of otosclerosis, as well as of eardrum perforation.

    Opis:
    Introduction: Chronic otitis media is characterized by tympanic membrane perforation and conductive hearing loss. In the active form of this disease, there will also be periodic or permanent otorrhea. With a number of surgical techniques available depending on intraoperative findings, otosurgery is the treatment of choice in such cases, the extent of which depends on the type and extent of the pathological changes. Material and Method: We carried out an analysis of 79 patients with chronic otitis media undergoing surgery at the Department of Otolaryngology, Jagiellonian University Medical College in Kraków between 2005 and 2014. Total audiometry was used as a part of hearing assessment, before the surgery, 6 months after the surgery and in the distant 10-year observation period. In addition, each patient completed the questionnaire and was examined by an otolaryngologist. Results: The analysis included 79 patients operated on due to chronic otitis media. The mean bone conduction (for frequencies 500,1000 and 2000 Hz) before surgery was 31.8 dB, it did not differ significantly (p = 0.355) after 6 months after surgery (32.8 dB), while it significantly increased (p < 0.001) in a distant 10-year control of 43.4 dB. The mean air conduction (for frequencies 500, 1000 and 2000 Hz) before the procedure was 57.6 dB, it significantly improved in the early control by 50.5 dB, at p < 0.001. In long-term follow-up it increased again to 61.3 dB and was significantly different from the early postoperative period (p < 0.001). The mean air-bone gap for frequencies 500, 1000 and 2000 Hz before surgery was on average 26.4 dB, it was significantly (p < 0.001) reduced in the postoperative period by 17.6 dB. The level of air-bone gap remained at a similar level in distant control. Conclusions: (1) A completely preserved ossicular chain in the absence of active chronic otitis media is the best prognosis for stable hearing improvement over the years with normal inner ear function; (2) Reoperation worsens the long-term results of a hearing test compared to the first operation.
