“…In recent decades, the endoscope has also been widely used in ear surgeries, such as myringoplasty, tympanoplasty and cholesteatoma surgery . Endoscopic surgical techniques preserve as much middle ear mucosa as conventional techniques do, thus yield comparable postsurgical hearing outcomes …”

Similar to caloric and rotational chair tests, vHIT reflects the function of the entire semicircular canal VOR pathway but cannot identify whether a peripheral vestibular sensory organ or vestibular nerve is damaged. The diagnostic value of vHIT is high (sensitivity of 87.9% and specificity of 94.8%) for VN, and other types of acute vertigo and its positive predictive and negative predictive values have been reported as 85.3% and 95.8%, respectively. 9 vHIT, as a high-frequency measure tool, is a useful complement to caloric and rotational tests. | CONCLUSIONSThe present study showed that vHIT results were different in VN and SHLV groups, which may underlie different aetiologies of VN and SHLV; thus, further study will be necessary to confirm these results and determine the different aetiologies.The exclusive transcanal endoscopic tympanoplasty with tragal perichondrium is feasible, high success rate and good hearing results.This method also had the advantages of the minimised, better cosmetic results and free of suture.

“…Endoscopic assisted middle ear surgery or observational endoscopic ear surgery might benefit from the localization of residual or recurrent cholesteatoma in hidden areas of the sinus tympani and facial recess. Recently, feasibility of TEES as a microscope replacement has been proposed by demonstrating the safety of TEES without significant complications in both adult and pediatric patients [11]. In addition, TEES does not have the morbidity associated with a post auricular incision and TEES has a short recovery time [2].…”

“…Endoscopic ear surgery (EES) has several advantages over conventional surgical microscopy. There is a wider field of view, improved resolution with high magnification, and the ability to "see around corners," allowing direct visualization of normally hidden recesses [2]. The external auditory canal (EAC) is typically used as the approach for surgery, obviating the need to create access pathways or retract soft tissues [3][4][5].…”

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.
