Computer Simulations of Transcanal Endoscope Ear Surgery

2019
The surgical field within the middle ear is small, has been, up until recently, largely hidden from view, difficult to visualize, and filled with tiny, delicate anatomical structures. Thus, surgeons operating in the middle ear had to, by necessity, gather critical information only after they expose the surgical field as they perform microscopic ear ...

Prolonged Radiant Exposure of the Middle Ear during Transcanal Endoscopic Ear Surgery

Otolaryngology–Head and Neck Surgery, 2015
Transcanal endoscopic ear surgery (EES) provides a high‐resolution, wide‐field view of the middle ear compared with the conventional operating microscope, reducing the need for a postauricular incision or mastoidectomy. Our group has shown in cadaveric human temporal bone studies that radiant energy from the endoscope tip can quickly elevate ...

Transcanal endoscopic middle ear surgery in children with chronic suppurative otitis media

Vestnik otorinolaringologii, 2021
Otomicroscopic surgery remains the gold standard in the surgical treatment of patients with CHS. Endoscopic ear surgery is gaining more and more importance as an adjunct to microsurgery. Recently, thanks to the resolution of the endoscopic technique, endoscopic surgery can be used as an independent method.

Safety of heat generated by endoscope light sources in simulated transcanal endoscopic ear surgery

Auris Nasus Larynx, 2016
To determine whether heat generated by endoscope light sources during ear surgery is safe.Transcanal endoscopic ear surgery (TEES) was simulated using 2.7-mm or 4-mm endoscopes coupled to xenon or LED light sources and a 3D model of human temporal bone. The endoscope tip was fixed at the center of tympanic annulus. Light sources were tested at clinical

Transcanal endoscopic ear surgery for pediatric external auditory canal cholesteatoma

International Journal of Pediatric Otorhinolaryngology
External auditory canal cholesteatoma (EACC) is an uncommon benign disease, which occurs rarely in children. Transcanal endoscopic ear surgery (TEES) has been proved a safe and feasible technique for treating adult EACC, no study has reported TEES in pediatric EACC.
