“…Furthermore, different types of ear surgery are being performed using an endoscope, with comparable results to those of traditional microscopic procedures. 11,[26][27][28] A few studies have utilised an endoscopic transcanal approach for decompression of the facial nerve. Marchioni and colleagues, in 2011, described the dissection of the tympanic segment of the facial nerve, from the geniculate ganglion to the second genu, in 12 temporal bone specimens and 2 patients with chronic middle-ear disease.…”

Objective The current study evaluated the effectiveness of endoscopic transcanal facial nerve decompression in patients with post-traumatic facial nerve paralysis. Methods This retrospective study included 10 patients with post-traumatic complete facial nerve paralysis who underwent endoscopic transcanal facial nerve decompression. The surgical technique was explained step by step, and the surgical complications, hearing status and facial nerve function 12 months post-operatively were reported. Results Endoscopic transcanal facial nerve decompression allowed exposure of the geniculate ganglion to the mastoid segment. The facial nerve function improved from House–Brackmann grade VI to grades I and II in 8 of 10 (80 per cent) patients, and 2 patients experienced partial recovery (House–Brackmann grades III and IV). No severe complication was reported. Conclusion Endoscopic transcanal facial nerve decompression, involving the nerve from the geniculate ganglion to the mastoid segment, is a safe and effective approach in patients with post-traumatic facial nerve paralysis.

“…These results indicated that ossiculoplasty during TEES is reasonable. Although some studies on endoscopic ossiculoplasty have been reported [ 10 , 11 ], the efficacy and safety of endoscopic ossiculoplasty have not yet been fully evaluated. TEES requires a long learning curve for many otologists because of its one-handed surgical technique and lack of depth perception [ 12 ].…”

Background Transcanal endoscopic ear surgery (TEES) reportedly requires a long learning curve and may be associated with more complications and longer operative times than microscopic ear surgery (MES). In this study, we aimed to examine the usefulness and validity of TEES for ossicular chain disruption in the early stages of its introduction in our institution. Methods TEES was performed on 11 ears (10 with congenital ossicular chain discontinuity and 1 with traumatic ossicular chain dislocation), and MES was performed with a retroauricular incision on 18 ears (6 with congenital ossicular chain discontinuity and 12 with traumatic ossicular chain dislocation) in a tertiary referral center. Postoperative hearing results, operative times, and postoperative hospital length of stay were retrospectively reviewed. The Mann–Whitney U test and Fisher’s exact test was performed to compare variables between the TEES and MES groups. Pre- and postoperative air- and bone-conduction thresholds and the air–bone gap of each group were compared using the Wilcoxon signed-rank test. The Mann–Whitney U test and Wilcoxon signed-rank was performed to compare the pre- and postoperative air–bone gaps between the diagnoses. Results No significant differences in the postoperative air-conduction thresholds, bone-conduction thresholds, air–bone gaps, or incidence of air–bone gap ≤ 20 dB were observed between the TEES and MES groups. The air-conduction thresholds and air–bone gaps of the TEES group significantly improved postoperatively. The air-conduction thresholds and air–bone gaps of the MES group also significantly improved postoperatively. No significant difference was observed in the operative times between the groups (TEES group: median, 80 min; MES group: median, 85.5 min). The TEES group had a significantly shorter postoperative hospital stay (median, 2 days) than the MES group (median, 7.5 days). Conclusions TEES was considered appropriate for the treatment of ossicular chain disruption, even immediately after its introduction at our institution. For expert microscopic ear surgeons, ossicular chain disruption may be considered a suitable indication for the introduction of TEES.
