BACKGROUND: Patulous eustachian tube is a disorder that leads to disturbing symptoms such as autophony, respiratory noise, and aural fullness. There has not been an established treatment found for this disorder. This study aims to assess the efficacy of autologous fat injection for a novel treatment of patients with patulous eustachian tube.

METHODS: Twenty-eight patients with refractory patulous eustachian tube were recruited for the study. Endoscopic autologous fat injection was performed submucosally into the anterior and posterior portion of the pharyngeal orifice of the eustachian tube. The outcomes were quantitatively assessed by comparing the difference between pre- and postoperative scores with the visual analog scale on 4 criteria: aural fullness, respiratory noise, tinnitus, and autophony.

RESULTS: Autologous fat injection was performed successfully in all patients without major complications. According to the combined visual analog scale scores, after the treatments, 20 patients showed significant improvement and 6 showed moderate improvement. The overall success rate of the treatment was 92.9%.

CONCLUSION: Autologous fat injection is an effective and safe procedure for the treatment of patulous eustachian tube.
