“…Because the middle ear is hidden inside the temporal bone and has limited accessibility, several strategies have been developed to visualize its anatomy (Tschabitscher and Klug, ). Due to these difficulties, to date, simulations have gained increasing popularity in otolaryngology, especially for teaching the surgical anatomy of the middle ear and procedures used to treat it (Javia and Deutsch, ; Javia and Sardesai, ), including computer‐based simulations (Abou‐Elhamd et al, ; Clifton et al, ; Francis et al, ), problem‐based learning (Abou‐Elhamd et al, ), simulations using three‐dimensional synthetic models (Mills and Lee, ; Bakhos et al, ; Rose et al, ; Barber et al, ; Luu et al, ; VanKoevering and Malloy, ) and even animal models (Anschuetz et al, ).…”

Teaching methodologies for the anatomy of the middle ear have not been investigated greatly due to the middle ear's highly complex structure and hidden location inside of the temporal bone. The aim of this randomized study was to quantitatively compare the suitability of using microscope-and endoscope-based methods for teaching the anatomy of the middle ear. We hypothesize that the endoscopic approach will be more efficient compared to the microscopic approach. To answer the study questions, 33 sixth-year medical students, residents and otorhinolaryngology specialists were randomized either into the endoscopy or the microscopy group. Their anatomical knowledge was assessed using a structured anatomical knowledge test before and after each session. Each participant received tutoring on a human cadaveric specimen using one of the two methods. They then performed a hands-on dissection. After 2-4 weeks, the same educational curriculum was repeated using the other technique. The mean gains in anatomical knowledge for the specialists, residents, and medical students were +19.0%, +34.6%, and +23.4%, respectively. Multivariate analyses identified a statistically significant increase in performance for the endoscopic method compared to the microscopic technique (P < 0.001). For the recall of anatomical structures during dissection, the endoscopic method outperformed the microscopic technique independently of the randomization or the prior training level of the attendees (P < 0.001). In conclusion, the endoscopic approach to middle ear anatomy education is associated to an improved gain in knowledge as compared to the microscopic approach. The participants subjectively preferred the endoscope for educational purposes. Anat Sci Educ 12: 507-517.

“…Transtympanic and transtubal endoscopy of the middle ear was reported by Tschabitscher and Klug. 7 Karhuketo et al 8 concluded that with 308 and 908 endoscopes, one can visualize signi cantly more structures in the middle ear than with an otomicroscope.…”

Otoendoscopy is a new technique in otological surgery. The traditional surgery for otitis media with effusion (OME) is myringotomy and tube insertion using an operating microscope. In 45 children and five adults presenting to our department with otitis media with effusion, rigid endoscopic myringotomy and grommet tube insertion were performed using 2.7 mm diameter and 0 degree and 30 degrees angle telescopes under general anaesthesia for children and local anaesthesia for adults. The use of rigid endoscopes provides a large field of view, that is of excellent resolution and fidelity of colour as well as giving good side views. It can be performed in the out-patient clinic with little inconvenience to the patient and minimal risks.

Two-Port Endoscopy of the Middle Ear

Abstract: Two-port endoscopy of the middle ear offers a full view of all structures in the tympanic cavity. The atraumatic transtubal approach to the tympanic cavity enhances the safety of transmeatal interventions and facilitates postoperative follow-up.
