Incidence of anesthetic and surgical complications in laryngeal laser surgeries

Introduction: Carbon dioxide (CO2) laser is an available technological tool for laryngeal surgeons. Given the importance of laser outcomesand complications, this research was conducted to identify the complications associated with laser surgery in the patients referring to the5th Azar Medical-Educational Center in Gorgan, Iran, from 2013 to 2017. Methods: This descriptive cross-sectional study was conducted on 85 patients with laryngeal lesions who underwent microscopic surgerywith CO2 laser at the 5th Azar Medical Educational Center in Gorgan, Iran, from 2013 to 2017. The patients were examined for the associated short-term complications 1, 7, and 21 days after the operation. They were also examined after 3 months to determine the long-term complications and patient satisfaction with sound quality. The data were analyzed in SPSS software (version 16). A p-value less than 0.05 was considered statistically signifificant. Results: Out of the 85 patients undergoing laser surgery, 60 (70.6%) cases were male. None of the patients experienced short-term complications. In terms of long-term complications, 2 (2.35%) cases, who had failed to perform the follow-up, had recurrent lesions after 3 months of surgery. In addition, 18 (21.8%) subjects had recurrent hoarseness, 18.8% (n=16) and 2.35% (n=2) of whom were detected with laryngeal carcinoma and recurrence, respectively. However, a total of 67 (78.91%) cases did not suffer from long-term complications. In this study, out of 85 patients undergoing larynx surgery, 69 (81.2%) cases had benign pathology, while the rest (n=16, 18.8%) had malignant pathology. Conclusions: It seems that a CO2 lasersurgery that follows scientific principles can produce good outcomes.
