Abstract

Purpose: To describe the surgical procedure of exclusive endoscopic ossiculoplasty (EEO) with autologous grafts and evaluate audiological results, focusing on the advantages or drawbacks compared to the corresponding microscopic technique.

Methods: A retrospective review of consecutive adult and pediatric patients affected by chronic otitis media (COM) with or without cholesteatoma who underwent EEO was conducted. Only autologous ossiculoplasty was included in the study. The procedure was performed by experienced surgeons of our institution between November 2014 and September 2019. Hearing outcomes were evaluated using postoperative air-bone gap (ABG) and success rates in different subgroups of patients and different types of ossiculoplasty (OPL) were analyzed. Our results were finally compared with the existing literature regarding both microscopic and endoscopic ossicular chain reconstruction.

Results: In total, 74 endoscopic ossicular chain repair procedures performed within the study period met the inclusion criteria. Of these, 21 were pediatric patients (28%) and 53 were adults (72%). Surgical reconstruction procedures included 43 partial ossicular reconstructions (POR) and 31 total ossicular reconstructions (TOR). The postoperative ABG improved significantly compared to preoperative measurements, and the mean ABG closure was 7.85 dB HL (p = 0.00064). No statistically significant differences in audiological outcomes between TOR/POR techniques and pediatric/adult groups were found in our study cohort, with p values of 0.10 and 0.88, respectively.

Conclusions: At present, EEO can be considered a valid surgical option for re-establishing a functioning ossicular chain with acceptable hearing restoration in children and adults. Further reports in wider case series are required to confirm these results.
