Background:
The effects of endoscopic sinus surgery (ESS) on the symptom burden of Eustachian tube dysfunction (ETD) in chronic rhinosinusitis (CRS) patients were investigated.
Methods:
Ninety-two patients with CRS following ESS were prospectively enrolled and followed up every 3 months for 1 year. The 7-item ETD Questionnaire (ETDQ-7) and 22-item Sino-Nasal Outcome Test (SNOT-22) were administered before ESS and at each visit following ESS.
Results:
Before surgery, 25% of patients reported ETDQ-7 scores ≥ 14.5, indicating the presence of ETD. The mean preoperative ETDQ-7 and SNOT-22 scores were 13.3 and 40.0, respectively. The mean ETDQ-7 and SNOT-22 scores were significantly decreased to 8.2 and 17.0 at 1 year following ESS, respectively. Most patients reported alleviation of their symptoms within the first 3 months, and the prevalence of ETD had decreased to 3.3% at 1 year. Patients who received revision surgery had higher ETDQ-7 scores during the follow-up period. Additionally, 5.4% of patients reported worsening of their symptoms.
Conclusion:
ETD symptoms can be effectively alleviated in most patients within 3 months following ESS. However, 5.4% of patients reported worsening of their symptoms at the 1-year follow-up. Additional objective studies should be conducted to evaluate Eustachian tube function thoroughly in CRS patients.
