“…(15,20) The cholesteatoma was lying deep in sinus tympani in these cases which could only be viewed by angled telescope and removal of stapes suprastructure was necessary to eradicate the disease from this area. Thus, we agree with Ajalloueyan M et.al 7 and El-Meselaty k et.al 21 that usage of otoendoscope in cholesteatoma surgery is important as it will help to reduce the incidence of residual disease in mastoid surgery. The principle of creating a dry and self-cleaning mastoid cavity involves extensive surgery.…”

“…In otologic practice, due to the complex anatomic structure of the surgical area, the use of endoscopes has risen during the past three decades. During the past 10 years, the incidence of radical ear surgery reduced due to the widespread use of the endoscopes in otologic surgical procedures [3,11]. Endoscopes are illuminated by fiber optic cables parallel to the optical system of the light source.…”

The objective of this study was to investigate the thermal effects of cold light sources and endoscopes on the inner ear. 25 male guinea pigs were assigned equally to five groups (1: Halogen-1 min, 2: Halogen-5 min, 3: Xenon-1 min, 4: Xenon-5 min, 5: Controls). After both bullae of the guinea pigs were opened, light sources and endoscopes were positioned in the middle ears of the first four groups for specific time periods. DPOAE and ABR tests were conducted on all animals at the beginning of the study, at the end of surgery, and 2 h after surgery. The temperatures of cold light sources were measured by a thermocouple thermometer, and the surface temperatures of the endoscopes were measured by an infrared thermometer. DPOAE and ABR measurements performed right after and 2 h after surgery in group 1, 2, 3, and 5 did not reveal any significant difference. In group 4, DPOAE values were significantly lower and ABR threshold values were significantly higher than those in the other groups, right after and 2 h after surgery. Thermocouple thermometer readings showed that, after the first minute, the Xenon light source generated significantly more temperature rise than the Halogen light source. The surface temperatures of all endoscopes returned to normal approximately 1 min after light sources were turned off. Our study demonstrated that when an endoscope using a Xenon light source was applied to the middle ear for a specific time periods, inner ear functions deteriorated, as reflected by audiologic tests.

“…The authors suggested the use of endoscopes with different angles to explore the sinus tympani; especially 30, 45 and 70°telescopes allow a better control of the middle ear cavity. Badr-El-Dine [6] and El-Meselaty et al [19] studied utility of the endoscope during cholesteatoma surgery and they found that endoscopic approach to sinus tympani gave a better exposition of the sinus thus achieving better pathology eradication.…”

“…This is confirmed by other studies reported in international literature, which showed the same results. This is particularly true especially when the sinus tympani is deep [19][20][21][22]. For this reason it might be very useful for the surgeon to study the extension of the ST before the surgery.…”

Good knowledge of anatomy is fundamental for every surgeon. Middle ear anatomy is really complex and sometimes is challenging for otologists, who need to explore every single compartment for a radical removal of pathology. With introduction of the endoscope in middle ear surgery, anatomy of middle ear spaces has become wider and clearer due to a better magnification and to the possibility to look ''behind the corner''. This article is a review of the state-of-art of endoscopic middle ear anatomy with description of every compartment, with particular attention to ventilation pathways and middle ear folds.
