The study of otoendoscopic tympanoplasty (type I)

Background With the development of otoendoscopic surgery technology and the update of equipment, more and more otoendoscopic tympanoplasty are carried out.Objectives To investigate application of otoendoscopic tympanoplasty.Methods Seventy-six patients with tympanic membrane perforation were randomly enrolled into otoendoscopic group (OP, n = 38) and microscope group (MP, n = 38). We compared two-group patients using operative time, intraoperative blood loss, healing of postoperative perforations, and degree of postoperative hearing improvement.Results Average operation time was statistically significant shorter in the OP than the MP (p < .05); the intraoperative blood loss in the OP was significant less than MP (p < .05); after postoperative follow-up, the healing rate of tympanic membrane perforation was 92.11% in the OP compared to 89.47% in the MP. However, there was no statistically significant difference in the two groups (p > .05). There were no statistically significant differences between the preoperative and postoperative air and bone conduction thresholds in the two groups (p > .05).Conclusions Otoendoscopic tympanoplasty is a minimally invasive operation but with similar effects as compared to microscopic one. But the operation time and intraoperative blood loss in the OP were significantly better than those in the MP, thus it is a safe, effective and easy to be operated in clinical practice.
