“…Indeed, traditional 2D and modern 3D endoscopic techniques have recently been compared for surgeons performing endoscopic ear surgery. 9,19 Here, 3D endoscopy was shown to be suitable for endoscopic ear surgery and to have advantages, especially for less experienced surgeons. Taken together, the advantages of the endoscopic view and dissection of the middle ear appear to be superior to the microscopic technique (theme A5).…”

Objective Endoscopic ear surgery is gaining popularity as a minimally invasive surgical technique for middle ear diseases. Its ongoing implementation into clinical routine has consequences regarding teaching of middle ear anatomy and surgery. To improve undergraduate and postgraduate training, we investigated the perception of and preference for endoscopy as compared with microscopy at different educational levels. Study Design Qualitative study based on a thematic analysis approach. Setting Tertiary academic medical center. Methods After a standardized curriculum was run on endoscopic and microscopic anatomy and surgical skills education, 5 focus groups were held. The interviews were conducted, video recorded, transcribed, and analyzed. Analysis of the data gave rise to 11 themes showing the participants’ perceptions and preferences. Results Five medical students, 11 otorhinolaryngology residents, and 3 staff members participated in this qualitative study. For anatomy teaching, there was a clear preference for the endoscopic technique. The main advantages were the enhanced overview and perception of the anatomic details provided through endoscopy. For skills acquisition, the perceived advantages of the techniques were the same view of the surgical field for endoscopy and the 2-handed surgical technique for microscopy. However, there was no clear preference between the techniques for skills acquisition. Conclusion The endoscopic technique was generally judged more beneficial for teaching anatomy, especially due to the greater visualization of the complex middle ear anatomy. Given that both techniques will remain important to future surgeons, the relative unique benefits of each must be considered when designing and optimizing curricula for otologic education.

“…Unlike microscopically-trained surgeons, the mental model of endoscopic native surgeons is not yet consolidated. Similar to the literature regarding 3D endoscopy [ 15 ] the implementation of a relatively new technique by young surgeons may be facilitated by the more flexible mental representation of the technique. In contrast, microscopically experienced surgeons have to transform their fixed two-handed stereoscopic mental model into a one-handed two-dimensional model.…”

Purpose Type I tympanoplasty is one of the first operations to be performed by ear surgeons in training and is increasingly performed using the endoscopic technique. The aim of the present study is to assess and compare the learning curve for type I tympanoplasties between a microscopically trained and endoscopic native ear surgeon. We hypothesize comparable learning curves between the two surgeons regardless of previous microscopic experience. Methods Retrospective analysis and comparison of the 25 first consecutive cases of type I tympanoplasty performed by a microscopically trained ear surgeon (MTES) and a native endoscopic ear surgeon (NEES). Results Mean duration of surgery in MTES and NEES groups was 54 ± 12.3 min and 55.6 ± 17.5 min, respectively. Both surgeons achieved a reduction of the surgery duration over time with statistically significant reduction from the first five cases to the last five cases in both groups. Graft intake rate was 92% after 3 months. Preoperative and postoperative PTA revealed a mean improvement of air bone gap (ABG) of 11.5 ± 7.1 dB HL in MTES group versus 9.3 ± 8.5 dB HL in NEES group, whereby the difference between the two groups was not statistically significant. Conclusion Endoscopic type I tympanoplasty shows comparable results and learning curves in two beginning endoscopic ear surgeons independent of the previous microscopic experience. We recommend if available the parallel learning of both techniques.

“…Many surgeons including the 2 authors have found the use of 3D endoscopy very helpful and there is evidence from other specialties that this is associated with a shorter learning curve and better depth perception. 11 At present, all 3D endoscopes require a 10 mm port against a 5 mm port for a high-definition 2D camera. We feel the extra 5 mm is a price worth paying but this needs to be evaluated by each surgeon to compare the pros against the cons (Table 1).…”
