Background and objectives: In recent years, long-term azithromycin (AZT) use has been increased in pediatric patients with chronic respiratory tract problems. In this study, we aimed to assess auditory functions in children on long-term AZT therapy. Method: The study included 43 patients who received long-term AZT treatment and 27 age-matched, healthy controls. In the study and control groups, ear-nose-throat examination, pure tone audiometry, speech recognition threshold (SRT), speech discrimination score (SDS), uncomfortable loudness level (UCL), acoustic reflex tests, and otoacoustic emission tests were performed. The test results were statistically compared between groups. Results: Mean age was 11.3 +/- 0.56 years in the study group and 9.3 +/- 3.07 years in the control group. The medain hearing examination was 8 months after end of AZT treatment (Ranged: 1-12 months). No significant difference was found in normal- and high-frequency audiogram tests at any frequency between study and control groups. Also, no significant difference was found in distortion product otoacoustic emissions (DPOAE) and transient evoked otoacoustic emissions (TEOAE) tests between groups. Also, there was no significant difference in acoustic reflex, SRT, SDS, and UCL test results between study and control groups. Conclusion: This is the first study assessing auditory functions comprehensively in pediatric patients who received long-term AZT therapy. In this study, it was shown that long-term AZT use had no deleterious effect on auditory function tests.
