RESUMEN
Objective:To compare the expression levels of SCCAg in inverted papilloma of the nasal sinuses and other sinuses and sinus masses. To investigate the correlation between the expression of SCCAg in sinonasal inverted papilloma and outcome. Methods:Sixty-eight patients with unilateral nasal and sinus masses admitted to the Otorhinolaryngology Center of the Affiliated Hospital of Guangdong Medical University from September 2020 to February 2023 were randomly selected, including 31 patients with inverted papilloma ï¼experimental groupï¼ and 37 patients with unilateral nasal and sinus masses excluding inverted papilloma ï¼control groupï¼. The application of automatic chemiluminescence immunoassay to test the serum SCCAg of the experimental group before surgery and 1 week after surgery, and the control group to measure the serum SCCAg before surgery. Clinical data were also collected. Results:There was no significant difference between the experimental group and the control group in gender and preoperative peripheral blood inflammatory indicators. However, there was significant difference in age and preoperative serum SCCAg levelï¼P<0.001ï¼. The serum SCCAg levels of the experimental group before and 1 week after surgery were significantly differentï¼P<0.001ï¼. The positive predictive value, negative predictive value, sensitivity and specificity of serum SCCAg in the diagnosis of varus papilloma were 92.6%, 85.4%, 77.4%, 94.6% and 0.72, respectively. The effect of serum SCCAg in the diagnosis of varus papilloma was analyzed by drawing the subject's working characteristic curve, and the area under the curve was 0.968ï¼P<0.001ï¼. When serum SCCAg greater than 2.7 ng/mL, the sensitivity and specificity were 67.7% and 94.6%, respectively. There was statistical significance in serum SCCAg levels between patients with and without recurrenceï¼P<0.05ï¼. Conclusion:The level of SCCAg in unilateral nasal and sinuses tumors, excluding squamous cell carcinoma, was significantly increased in inverted papilloma. The detection of serum SCCAg can be used as a simple and cost-effective auxiliary diagnostic tool for patients with nasal inverted papilloma before operation. Significant differences in preoperative and postoperative levels can be used for preliminary evaluation of surgical efficacy. Monitoring the serum SCCAg level in patients with inverted papilloma after surgery can predict recurrence and provide a simple and feasible method for postoperative follow-up.

Objective:To observe the effect of nasal mucosa flap in the repair of nasopharyngeal skull base bone exposure after radiotherapy for nasopharyngeal carcinoma, and to provide a basis for the repair with nasal mucosa flap in skull base bone exposure after radiotherapy. Methods:The clinical data of 8 patients who underwent nasal endoscopic surgery were analyzed retrospectively. The survival of mucosal flap, the mucosal epithelialization of bone defect or exposed site, the improvement of main clinical symptoms and complications were followed up after operation. Results:Severe mucosal flap necrosis and bone exposure occurred in 1 case after operation, in the other 7 cases, the mucosal flap survived and the mucosal epithelium of nasopharynx recovered well. After operation, most of the patients' clinical symptoms such as headache and nasal odor were improved compared with those before operation. Conclusion:Nasal mucosal flap is a safe and minimally invasive autogenous material with good biocompatibility. It has a good application prospect in repairing bone defect or exposure of nasopharyngeal skull base after radiotherapy and is worth popularizing in clinic.
