“…Whichever prosthesis was used, good surgical results were reported. Gulsen and Karatas 19 and Pradron and Preetam 20 reported the acceptable results with PTFE prosthesis. Sproat et al 26 and Iannella and Magliulo 27 reported the satisfactory surgical results of endoscopic stapes surgery using titanium prosthesis.…”

“…Several groups reported the usefulness of endoscopic approach for stapes surgery (Figure 6). [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] There are several potential dilemmas for the surgeon when considering TEES. The nondominant hand of the surgeon is used for the endoscopic operation, leaving only 1 hand for the TEES surgery.…”

“…Previous case series of endoscopic stapes surgery with more than 10 cases are shown in Figure 6. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Most surgeons have used piston-type PTFE prosthesis or titanium (or its alloy: nitinol) prosthesis. Whichever prosthesis was used, good surgical results were reported.…”

Objectives: Hydroxyapatite is a commonly used material for medical applications due to its excellent biocompatibility. We use hydroxyapatite prosthesis for the reconstruction of the ossicular chain in stapes surgery. In this study, we report a case series of endoscopic ear surgery using a basket-type hydroxyapatite prosthesis. Methods: We retrospectively examined 8 cases of endoscopic transcanal stapes surgery using hydroxyapatite prostheses. We evaluated the postoperative results and complications. Results: The average postoperative air–bone gaps were within 10 dB in all cases. Postoperative sensorineural hearing loss was not observed in any case. There was an intraoperative complication with the chorda tympani in 1 patient. We were able to preserve the chorda tympani of all patients, including this case. Postoperative transient dizziness and transient taste disorder were observed in 50% of cases. No other complications, including facial nerve palsy, tympanic membrane perforation, or postoperative infection, were observed. Conclusions: The postoperative results and complications were comparable to those of surgery under a microscope. The hydroxyapatite prosthesis could be a possible alternative for the piston-type titanium or polytetrafluoroethylene prosthesis.

“…Multiple clinical studies on transcanal endoscopic SS have followed, showing no clinically relevant complications related to heat damage, nor on the facial nerve or the hearing and vestibular function [ 16 – 20 ]. This may be the result of the suggested technical strategies of half-intensity light source use, frequent aspiration of fluids and repeated cleansing of the endoscopic tip [ 21 , 22 ].…”

“…According to a Japanese study on 3D-printed temporal bone simulators, temperatures produced by an endoscope with LED light source are safe with a 2.7 mm optic coupled to a light intensity of 40% of the maximal output [15]. Multiple clinical studies on transcanal endoscopic SS have followed, showing no clinically relevant complications related to heat damage, nor on the facial nerve or the hearing and vestibular function [16][17][18][19][20]. This may be the result of the suggested technical strategies of half-intensity light source use, frequent aspiration of fluids and repeated cleansing of the endoscopic tip [21,22].…”

Purpose To compare hearing results and complication rates between two groups of patients operated on by endoscopic stapes surgery (ESS) for otosclerosis, either with CO2 fiber laser or microdrill. Methods A case–control study was performed. All consecutive cases of CO2 fiber laser ESS operated at a single center during the period 2017–2020 (case group) were matched to a control group of patients operated by traditional technique, according to year of surgery, preoperative mean air–bone gap, sex and age. Audiological data from preoperative and postoperative examinations and complication rates were compared. Results 46 cases were included. Mean operative time was significantly longer in the laser cohort (65 min) than in the drill one (45 min) (p = 0.003). Similar results were found in the two groups regarding the mean postoperative BC-PTA. The high-frequency bone conduction resulted significantly higher in the laser group (p = 0.002), suggesting an overclosure effect in the laser group. Consistently, a significant improvement of the BC-PTA threshold at 2000 Hz postoperatively was found in the laser group (p = 0.034). The postoperative AC-PTA significantly improved in both groups at all frequencies (p < 0.05), except for the AC threshold at 8 kHz. Similar rates of complications were found in the two groups. Conclusion This study is the first to compare hearing results and complications between CO2 fiber laser and microdrill in ESS. Our results demonstrated similar functional outcomes between the two groups, confirming ESS as safe and effective, regardless of the technique used.

BackgroundAlthough the utility of laser fiber in microscopic stapes surgery has been documented in the past, their role can be highly emphasized in endoscopic stapes surgery, especially in difficult anatomical situations.MethodsThis is a retrospective analysis of cases where a total of 46 patients (22 in conventional stapedotomy and 24 in CO2 laser‐assisted stapedotomy) were included in the study. The clinical parameters were assessed both in the preoperative and postoperative periods in the respective groups and later compared 12 weeks after stapedotomy.ResultsA total of 90.90% (20/22) of the patients in the conventional stapedotomy and 95.83% (23/24) of patients in laser‐assisted stapedotomy had <20 dB of AB gap in the postoperative period (P = 0.71). Canaloplasty was required in six patients in the conventional stapedotomy and none of the patients in the laser group needed the same (P = 0.01). Chorda tympani nerve was manipulated in 59.09% (13/22) and 25.00% (6/24) of cases in the conventional group and in the CO2 laser group, respectively (P = 0.01).ConclusionAlthough the audiological outcomes with fiber‐enabled CO2 laser in endoscopic stapedotomy are comparable to conventional surgery, it is a better tool in a narrow auditory canal, requiring minimal manipulation of the chorda tympani nerve.
