Early diagnosis and appropriate treatment of hoarseness is known to improve quality of life and treatment outcomes. Therefore, appropriate research on the incidence of hoarseness after surgery is necessary. In this study, investigator aim to investigate incidence of hoarseness after spine surgery and the correlation between the Voice Handicap Index (VHI)-10, used as a criterion, and acoustic parameters, while also validating the efficacy of our research methods.
The primary outcome of this study is the incidence of hoarseness on the day of surgery. The secondary outcomes include the incidence of hoarseness at one month after surgery, as well as examining the correlation between acoustic parameters, risk factors, and the occurrence of hoarseness. Investigator conducted a comparative analysis of risk factor for hoarseness in patients with different VHI-10 scores on the day of surgery and 30 days after surgery.

the primary outcome was to measure the incidence of hoarseness
the primary outcome was to measure the incidence of voice disorders by conducting Voice Handicap Index-10 (minimum score 0 to maximum score 46, lower score is better) scoring and voice recordings six hours after the end of anesthesia
Time frame: voice recordings six hours after the end of anesthesia
The secondary outcome involved measuring the incidence of hoarseness one month after the surgery
analyzed the correlation between Voice Handicap Index-10 (minimum score 0 to maximum score 46, lower score is better) scores and voice acoustic parameter analysis
Time frame: one month after the surgery
