“…Endoscopic Cochlear Implantation Cochlear implantation is one of the new applications of endoscopes in the field of otology, but there are few case series on this topic. In a recent study, Sharma et al 28 concluded that the visualization of the round window niche improved with the use of an otoendoscope with 1.9 mm in diameter for cochleostomy and insertion of the electrode; a similar conclusion was reached in the study by Jain A et al 29…”

Introduction The role of endoscopes in the ear, nose, and throat (ENT) field has been described since the 1980s; It started with endoscopic nasal surgeries, followed by otological and laryngological procedures, and, since then, it has experienced a rapid evolution. Endoscopes help otologists understand how to approach difficult areas of middle ear, as well as the physiology of middle ear cleft. Objectives Despite the introduction of endoscopes in the field of otology, microscopes are still widely used in clinics and in operation theaters either alone or with endoscopes. The present study, which was conducted amongst otologists in India, is on their experience with and knowledge of the use of the endoscope compared to microscopes. Materials and Methods A Google form-based questionnaire comprising 18 questions was developed and sent online to otologist all over the country. The final dataset included responses from 354 active otologists. Results Out of 354 participants, only 3% had more than 5 years of experience in endoscopic ear surgery (EES), and 16.1% had never worked with an endoscope. Endoscopes were used in clinics and in operation theaters by 74.9% of the participants. Conclusion There has been a rise in the acceptance and use of endoscopes among Indian otologists and otology surgeons in last few decades.

“…Even group III patients were eligible for RW cochleostomy. 25 In 2015, Tarabichi, a pioneer of endoscopic ear surgery, set out to investigate (with computerised tomography scans of the sinuses and temporal bone) whether the transcanal endoscopic approach to the basal turn of the cochlea is suitable for CI. According to their measurements, they reported that the basal turn of the cochlea is positioned in a more posterior angle than the external ear canal, and therefore, they concluded that a PT approach is easier and safer because it offers a better alignment with the basal turn of the cochlea.…”

“…In 93 CI, a PT was performed and the endoscope facilitated recognition and magnification of RW and the electrodes were placed through the facial recess. [21][22][23][24][25][26] In 31 CI, the endoscope was used exclusively (without a microscope) throughout the procedure. 27,28 The active electrode was buried in a trough drilled on the wall of the posterior ear canal and obliterated with fascia, soft tissue flap or bone dust.…”

Cochlear implants can achieve hearing rehabilitation in individuals with severe and profound sensorineural hearing loss (SNHL) who have little benefit from hearing aids. 1 The conventional microscopic technique was first described in 1976 by House. 2 This traditional approach requires a transmastoid posterior tympanotomy (PT) under a microscopic view. Electrode insertion is achieved either through the round window (RW) or through a bony cochleostomy. 3 Although the success of this approach is undeniable, alternative surgical approaches have been proposed to avoid mastoidectomy complications and minimise the invasive nature of the surgery. [4][5][6] Additionally, PT does not always guarantee satisfactory exposure of the round window niche (RWN) through the facial recess (FR) due
