Discussion on the Transoral Vestibular Approach Endoscopy for TC Patients and the Significance of Serum 25-Hydroxyvitamin D Classification

In order to discuss the transoral vestibular approach endoscopy through oral vestibular approach in TC and the efficacy of 25(OH)D classification, a total of 110 TC patients from January 2020 to June 2021 are selected. The endoscopic group and the control group are respectively established according to different surgical approaches, with 55 cases in each group. The control group received conventional TC resection, while the endoscopic group received endoscopic assisted TC resection through oral vestibular approach. The differences of intraoperative and postoperative indicators, clinical efficacy, incidence of adverse complications, VAS score, and total satisfaction are observed. TC resection assisted by endoscopy through oral vestibular approach can effectively improve all intraoperative indicators and reduce postoperative pain and has high safety in clinical application. In addition, this study conducted in-depth analysis and classification of serum 25(OH)D index level in postoperative TC patients, indicating that the serum 25(OH)D index level is closely related to prognosis, providing a basis for follow-up clinical monitoring of TC patients' signs and optimization of diagnosis and treatment plans.
