ABSTRACT
Background:
Transcanal endoscopic ear surgery (TEES) for traumatic ossicular injuries (TOI) is not well studied.Objectives:
To analyze the treatment outcomes of TEES for TOI.Material andmethods:
Retrospective case review of fifteen patients (15 ears) with TOI was performed. The patients underwent an either ossiculoplasty or stapes surgery according to status of the ossicular chain using ear endoscopes. Postoperative audiometric results and complications were analyzed.Results:
All subjects demonstrated improvement in their air conduction threshold and air-bone gap (ABG). The mean preoperative air conduction threshold and ABG were 55.3 dB (SD 12.8) and 33.0 dB (SD 9.5), respectively. Postoperatively, the air conduction threshold and ABG significantly improved to 28.1 dB (SD 16.0) and 8.1 dB (SD 4.5), respectively. Separation of the incudomalleolar joint accompanied by defect of the tegmen, which was not discernible on preoperative imaging, could be identified without additional incision or mastoidectomy. No patients experienced complications or a sensorineural hearing loss. Conversion to open approach was not necessary for any of the 15 procedures performed.Conclusion andsignificance:
TEES for TOI yielded favorable audiometric results without any complication. TEES can provide an alternative method to manage TOI with the advantage of avoidance of skin incisions and mastoidectomy.Palavras-chave
