Objective: To examine the correlation between obesity and patient tolerance to office-based laryngeal procedures (OBLP) using multiple indices for obesity.

Study design: Retrospective chart review

Methodology: The medical records of all patients who underwent OBLP via the trans-nasal approach between February 2025 and September 2025 were reviewed. Office-based laryngeal procedures were divided into three categories: laryngeal biopsy, laser therapy with or without intralesional steroid injection, and therapeutic injection with pharmaceutical or autologous agents (steroids, botulinum toxin, hyaluronic acid and platelet rich plasma). Demographic data included age, gender, history of smoking, reflux disease, allergy, voice diagnosis, body mass index (BMI), neck and waist circumference. After the procedure, all patients were asked to fill out the IOWA satisfaction with anesthesia scale.

Results: Forty-three males and 39 females, mean age 50.56±16.60 years, were included in this study. The mean body mass index was 27.38±4.63 Kg/m2. The mean neck circumference was 38.17±7.73 cm and the mean waist circumference was 91.52±15.06 cm. The mean IOWA satisfaction with anesthesia scale score was 2.18±1.09. There was a statistically significant difference in the mean IOWA scores between the subgroups of patients with BMI < 25 Kg/m2 and BMI ≥ 25 Kg/m2 (p=0.010). There was a mild non-significant negative correlation between neck circumference and IOWA satisfaction scores and between waist circumference and IOWA satisfaction scores. Subgroup analysis showed a mild negative non-significant correlation between neck circumference and between waist circumference and IOWA satisfaction scores in those who underwent office-based laser therapy

Conclusion: The results of this investigation showed a significant moderate negative correlation between BMI and IOWA score, and a mild negative correlation between neck circumference, waist circumference, and IOWA score. These results might be useful for patient selection and counseling before procedure.
