Totally endoscopic ear surgery and endoscope-assisted microsurgery are new concepts until this date and relatively few centers perform them. One otologic procedure currently gaining popularity is endoscopic tympanoplasty, which is an effective and minimally invasive technique. Advantages include better visualization of ossicles and middle ear recesses and elimination of a postauricular incision. Some authors advise that this procedure would have several disadvantages as increased operating time and the fact that most operations are one-handed.
This is a retrospective longitudinal study based on the analysis of clinical records of patients who underwent endoscopic transcanal tympanoplasty from june 2017 to december 2018 in a Brazilian tertiary hospital. The sample was composed by 26 patients with diagnosis of chronic otitis media. Outcames assessed were duration of surgery, intraoperative and postoperative complications, audiometric results and graft success.
The sample is composed by 26 patients: 15 male (57%) and 11 female (43%). Mean age was 39,9 ± 17,4 years (range 6-70 years). Duration of the procedure ranged from 30 to 90 minutes with a mean time of 55.8 +-14,1 minutes. There were no intraoperative complications, one patient had residual perforation after 2 months of clinical follow-up and six patients maintained an air-bone gap greater than 15dB.
Our results confirm that endoscopic tympanoplasty is safe and the short term outcomes are comparable with conventional surgery.
