Correlation between Diabetes Mellitus Type 2 and Patient Tolerance to Office-based Laryngeal Surgery

To investigate the correlation between Diabetes Mellitus type 2 (DMT2) and patient tolerance to office-based laryngeal surgery (OBLS).

Retrospective chart review METHODS: A retrospective review of all adult patients who underwent OBLS between November 2021 and June 2026 was conducted. Patients diagnosed with DMT2 based on ICD-10 coding and who had filled the Iowa Satisfaction with Anesthesia Scale (IOWA) and VAS score for tolerance were included. A control group that also underwent OBLS was matched by age, gender, smoking status, and history of reflux disease. Additional clinical data included glucose levels and HbA1c.

The study included 59 diabetic and 59 non-diabetic patients. The mean IOWA score was 1.99 ± 1.15 for diabetics and 2.15 ± 1.05 for controls (P = 0.518). The mean VAS score for tolerance was 7.68 ± 2.30 and 7.47 ± 2.32 for controls (P = 0.591). A weak negative non-significant correlation was observed between IOWA scores and disease duration (r = -0.196, P = 0.318) and between VAS scores and disease duration (r = -0.319, P = 0.098). There was a weak positive non-significant correlation between VAS scores and HbA1c (r = 0.103, P = 0.581).

The results showed no significant difference in tolerance score between those with diabetes vs those without diabetes. A study on a larger study group with a longer duration of disease is warranted.
