“…Our search highlighted several papers that had investigated the thermal effects of endoscopes commonly used in otology, 6 – 12 along with case reports of injuries that occurred when using endoscopes and cold light sources in general minimal access procedures such as laparoscopic surgery. No paper was identified that documented any negative effects as a result of thermal issues in patients who underwent endoscopic ear surgery.…”

“…Most papers reported measuring the temperature at the tip of the endoscope 6 – 8 , 10 , 12 or measuring temperatures directly in the light emitted from it at varying distances from the tip 8 9 , 11 The measurements were taken in a laboratory environment, in cadaveric human temporal bones or in live animal models.…”

“…Using an SER will reduce the frequency of endoscope removal from the surgical field; therefore other cooling methods should be implemented to ensure safety. These include the use of suction, turning off the light source at regular intervals, and the use of endoscope sheaths and saline irrigation [26,29].…”

Self-Expandable Retainer for Endoscopic Visualization in the External Auditory Canal: Proof of Concept in Human Cadavers

et al. 2020

This study was conducted to investigate the efficacy of a self-expandable retainer (SER) for endoscopic visualization of the external auditory canal (EAC). Tympanomeatal flap (TMF) elevation was performed in six cadaveric heads. Two different types of SER were placed. The procedural feasibility was assessed by endoscopic images. Technical success rate, procedure time, endoscopy lens cleaning, and presence of mucosal injuries were analyzed. TMF elevation and SER placement were successful in all specimens and there were no procedure-related complications. The mean procedure time with the SERs was significantly shorter than without (p < 0.001). The mean number of times the endoscopy lens was cleaned during the procedure was significantly lower in the SER group (p < 0.001). In the SER group, endoscopy insertion into the EAC was easier without tissue contact with the lens during the TMF elevation compared with the non-SER group. There were no mucosal injuries. SER placement is effective for endoscopic visualization via the expanded and straightened EAC. A fully covered type of SER is preferable. The device can be useful for endoscopic ear surgery, reducing procedure time and reducing the need for endoscopy lens cleaning during the procedure.

“…In a distance of 5 mm, the body temperature is no longer exceeded. After turning off the light source, the temperature also decreased below body temperature within 2 minutes [ 525 ], [ 526 ]. Cooling can be achieved by using saline solution rinsing, suction devices, or endoscopic sheaths [ 525 ], [ 526 ].…”
