Abstract
Objective: To investigate the correlation between Diabetes Mellitus type 2 (DMT2) and patient tolerance to office-based laryngeal surgery (OBLS).
Methods: A retrospective review of all adult patients who underwent OBLS between November 2021 and October 2025 was conducted Patients diagnosed with DMT2 based on ICD-10 coding and had filled the Iowa Satisfaction with Anesthesia Scale (IOWA) scale were included. A control group who also underwent OBLS were matched by age, gender, smoking status and history of reflux disease. Additional clinical data included glucose levels and HbA1c.
Results: The study included 37 diabetic and 37 non-diabetic patients. The mean IOWA score was 1.91 ± 0.94 for diabetics and 2.37 ±0.67 for controls (p = 0.017). Multiple linear regression demonstrated a statistically significant negative association between diabetes status and IOWA score (β = −0.417, p = 0.002). No significant correlation was observed between IOWA scores and glucose levels (r = 0.257; p=0.446) HbA1c (r=0.267; p=0.522), or disease duration (r=-0.333; p=0.083)
Conclusion: The results of this investigation showed that patients with DMT2 had significantly less tolerance to OBLS than patients with no diabetes. A study on a larger study group with a longer duration of disease is warranted.
