Özet
Objective: To evaluate Eustachian function in the immediate and early late period after adenotonsillectomy. Methods: The study sample comprised children aged 4–14 years, who were diagnosed with adenotonsillar hypertrophy, then underwent adenotonsillectomy. All patients included in the study had normal preoperative Eustachian tube function. Tympanometry using 226 Hz and 1000 Hz probe tone, Eustachian function test (EFT), and audiometric examination were performed one day before and was then repeated on the first and 15th days after adenotonsillectomy. Results: A total of 256 ears of 128 patients were evaluated. According to the tympanometry results, on postoperative day one, Eustachian dysfunction in the right ear was determined in 80 (62.5 %) patients with 226 Hz probe tone and in 76 (59.3 %) with 1000 Hz probe tone, and these rates for the left ear were 79 (61.7 %) and 73 (57 %) patients, respectively. On the 15th day postoperatively, Eustachian function was determined to have recovered in the right ear of 75 of 80 (90.3 %) patients with 226 Hz probe tone and in 72 of 76 patients (94.7 %) with 1000 Hz probe tone (p = 0.0001). In the left ear, Eustachian function was determined to have recovered in the right ear of 73 of 79 (92 %) patients with 226 Hz probe tone and in 68 of 73 patients (93 %) with 1000 Hz probe tone (p = 0.0001). Conclusion: The study results showed that Eustachian dysfunction is common in the early period after adenotonsillectomy but almost all of these cases completely recovered by the 15th day postoperatively. Clinical trials number: NCT06577051.
