“…According to previous studies, ossicular erosions are relatively rare consequences and are therefore hard to predict in the most cases of tympanic membrane retraction (3,4). As it is shown in this study, occurrence of ossicular destruction at the level of long incus process in PTR without cholesteatoma is high (more than 60%); in contrast to other authors who have detected these lesions in only one third of their studied ears (4).…”

“…The mastoid is a functional organ that works as a ''buffer'' in regulating middle ear pressure [20,[27][28][29]. This ''buffer'' effect prevents retraction pocket formation and recurrence [30]. Consequently, a healthy antral mucosa and preservation of the mastoid permit the recovery of aeration of the mastoid postsurgery, as it is a functioning, physiological mucosa, active in gas exchange [31].…”

“…It is a functional organ and primarily acts as a buffer to pressure changes in the middle ear. This buffer effect prevents eardrum retraction, which has been thought to be associated with mucosal adhesion to the ossicles and subsequent hearing impairment [Borgstein et al, 2008]. Consequently, preserving the uninvolved mucosa in the antrum and mastoid leads to recovery of aeration and ciliary function in the mastoid during the post-operative period [Dornhoffer, 2000].…”

Objective: Following cholesteatoma surgery, effective long-term hearing preservation in children is difficult and is not typically expected. Hence, long-term data on hearing outcomes are lacking. The aim of this study was to analyze long-term hearing outcomes in children following cholesteatoma surgery. Methods: For this study, 49 ears in 47 children (≤16 years) with acquired cholesteatomas following atticotomy-limited mastoidectomy with cartilage reconstruction (inside-out approach) during 1986–2010 were included. Pre- and post-operative recidivism-free audiometric results were compared. Hearing success was defined as a post-operative air conduction (AC) threshold of ≤30 dB (serviceable hearing). Logistic regression analyses were used to evaluate potential prognostic factors that independently contributed to the prediction of hearing success. These factors included stapes condition, pre-operative AC threshold, ossicular chain integrity, disease severity, age, and gender. Results: The mean duration of follow-up was 14.2 years. The post-operative AC (33.55 ± 15.42 dB) and air-bone gap (17.88 ± 12.94 dB) were significantly improved compared with the pre-operative AC (42.90 ± 16.47 dB, p < 0.001) and air-bone gap (30.23 ± 13.68 dB, p < 0.001). The probability of hearing success following surgery (40.8%) was significantly higher than prior to surgery (24.5%, p = 0.008). Multivariate logistic regression analyses revealed a statistically significant correlation between hearing success and stapes integrity only (p = 0.005). Conclusions: This study provides important information on effective long-term hearing preservation over a mean follow-up of 14 years. In addition, stapes destruction is an independent negative prognostic determinant of achieving hearing success. The prediction model in this study provides otologists with useful pre-operative information to inform patients and parents on expected hearing outcomes and may be useful for post-operative observations.
