Clinical outcomes of exclusive transcanal endoscopic tympanoplasty with tragal perichondrium in 129 patients

Abstract

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.

Clinical outcome of exclusive endoscopic tympanoplasty with porcine small intestine submucosa in 72 patients

“…The graft take rate of endoscopic tympanoplasty with SIS was comparable to that reported for autologous tissue (approximately 84%-100%). 5,6,9,16 The graft take rate of tympanoplasty was also similar to those reported by D Small intestine submucosa has several advantages as a grafting material. First, it eliminates donor-site morbidity, postoperative wound pain and numbness.…”

“…SIS can provide enough material for grafting, regardless of the size of perforations. Furthermore, graft take rates of SIS in our study and other studies 3,8,18 are similar to those using autologous tissue grafts 5,6,9,16 . The advantages of SIS compared to graft with temporalis fascia are listed in Table 3.…”

“…In the present study, the overall success rate of tympanic membrane perforation closure was 94.7%. The graft take rate of endoscopic tympanoplasty with SIS was comparable to that reported for autologous tissue (approximately 84%‐100%) 5,6,9,16 . The graft take rate of tympanoplasty was also similar to those reported by D'Eredità 3 and Yawn et al 8 D'Eredità reported a high graft take rate of 96.3% in paediatric tympanoplasty performed under microscope through retroauricular approach.…”

“…Furthermore, graft take rates of SIS in our study and other studies 3,8,18 are similar to those using autologous tissue grafts. 5,6,9,16 The advantages of SIS compared to graft with temporalis fascia are listed in Table 3. Therefore, SIS provides a relatively convenient and time-saving method to pursue a tissue graft for repairing perforations.…”

“…Endoscopic ear surgery (EES) has become popular because of its benefits, lower traumatic risk, minimal invasiveness and excellent soft‐tissue preservation 9‐11 . EES has similar graft success rates and audiological outcomes to those of microscopic ear surgeries 12 .…”
