Objective:To compare the clinical effects and complications of surgery + chemotherapy and radiotherapy + chemotherapy in patients with nasopharyngeal carcinoma recurrence, so as to compare the safety and efficacy of two different therapeutic methods. Methods:A retrospective analysis was performed on 40 patients with recurrent nasopharyngeal carcinoma after radiotherapy and chemotherapy admitted to our hospital from January 2016 to June 2020. Among them, 26 patients were treated with surgery. The recurrent tumor was removed under nasal endoscope, and the frozen resection margin was negative during the operation. Chemotherapy was continued for stage Ⅲ and Ⅳ patients from 3 to 5 weeks after surgery. Fourteen patients received secondary radiotherapy and chemotherapy. Postoperative complications and survival rate were observed. Results:There were 14 patients in the secondary chemoradiotherapy group（control group） and 26 patients in the nasal endoscopic surgery group（observation group）. Among the 26 patients, 19 patients underwent nasal septal mucosal repair, 5 patients underwent temporal muscle flap repair, 2 patients underwent submental flap repair, 2 patients had nasal septal mucosal flap necrosis and cerebrospinal fluid leakage, and the temporal muscle flap was used for secondary repair in the second stage operation, and 8 patients needed cervical lymph node dissection. The patients recovered well after surgery, and the patients in stage Ⅲ and Ⅳ were treated with chemotherapy after 3 weeks to 5 weeks according to the patient's wound condition. There were significant differences in the incidence of complications and 1-, 2-, and 3-year survival rates between the two groups（P<0.05）. Conclusion:Patients with recurrent nasopharyngeal carcinoma can be treated by nasal endoscopic surgery to remove the tumor, and the use of pedicled nasal septal mucosal flap or temporal muscle flap for skull base reconstruction, The operation can effectively prevent major complications such as internal carotid artery rupture and hemorrhage, and improve the survival rate and quality of life of patients. It provides a safe and effective treatment for patients with recurrent nasopharyngeal carcinoma.

Objective: To explore the methods for the accurate resection of malignant tumors of the external nose, and the accurate evaluation and repair of tissue defects. Methods: We collected 48 cases with nasal malignant tumors treated in 980 Hospital, Joint Support Force of the People's Liberation Army from January 2010 to June 2020, including 28 males and 20 females, aged 36-86 years. The pathological types of tumors included basal cell carcinomas (n=29), squamous cell carcinomas (n=11), trichilemmal carcinomas(n=6), denoid cystic carcinoma (n=1) and non-Hodgkin lymphoma (n=1). Tumor resection was mainly based on the traditional extended resection determined by the safety margin, and Mohs surgery was used to minimize the scope of resection, for the margin that significantly affected the repairing results, such as the lesion adjacent to the nasal alar margin, nasal columella or deep easy-penetrating margin. All cases obtained tumor resection and primary/secondary defect reconstruction. Results: According to the pathological type and tumor size, the safe resection margin was mainly 4-10 mm, and Mohs surgery was used in 24 cases. Limited-size defects in 38 cases were repaired with double-leaf flaps, kite flaps, nasal dorsum brow flaps, nasolabial flaps or free tissues. Among 10 cases with compound defects, 8 cases were repaired with frontal flaps, including 4 cases with single frontal flaps, 2 cases with additional titanium mesh stent reconstruction and 2 cases with over and out frontal flaps. During follow-up of 1 to 10 years, all the flaps survived without flap necrosis, and the postoperative nasal contour and ventilation were satisfactory. One patient had tumor recurrence 18 months after operation, 2 patients died of cardiovascular and cerebrovascular diseases, and other patients survived without tumors. Conclusions: Mohs surgery can basically meet the requirements for precise resection of external nasal malignant tumors. Individualized application of adjacent tissue flaps and various frontal flaps is a reasonable choice to achieve the satisfactory outcome of external nasal repair and to take into account the complexity of operation.

Objective: To evaluate the feasibility of the endoscopic transnasal approach (ETA) and to analyze the outcomes and factors of this surgical technique in the management of the tumor invading the anterior skull base. Methods: A retrospective analysis was performed on 42 patients (31 males and 11 females, with mean age of 49 years) with sinonasal tumor invading the anterior skull base, who underwent ETA from June 2015 to April 2019 in Eye, Ear, Nose and Throat Hospital of Fudan University. Pathologically, there were 15 cases of squamous carcinoma (14 patients with T4bN0M0 and 1 patient with T4bN1M0) and 27 of olfactory neuroblastomas with Kadish stage C. Anterior skull base reconstruction was performed using the vascular pedicled nasoseptal mucoperiosteal flap and fascia lata. Brain non-contrast-enhanced CT was performed on the first postoperative day to exclude massive pneumocephalus, relevant brain edema and subarachnoid hemorrhage. Sinonasal contrast-enhanced MR was performed to assess the extent of the tumor removal. Kaplan-Meier analysis was used to calculate the overall survival (OS) and Cox multivariate regression analysis was used to determine the prognostic factors. Results: The mean duration of the surgery was 452 minutes. Total resection was performed in 36 patients (85.7%), subtotal resection in 2 patients (4.8%) with orbital involvement, partial resection in one patient (2.4%) with injury of the internal carotid artery. One patient (2.4%) underwent the second resection because of the tumor residual, two patients (4.8%) with unsure tumor residual. Mean follow-up was 20 months, with 17 months of median follow-up. One-, two-and three-year overall survival was 86.5%, 76.9% and 64.5%, respectively. For squamous carcinoma, one-, two-and three-year overall survival was 86.2%, 86.2% and 57.4%, respectively. For olfactory neuroblastomas, One-, two-and three-year overall survival was 86.9%, 75.3% and 67.8%, respectively. Multivariate analysis showed that tumor residual (P=0.001) and recurrence (P<0.01) were independent prognostic factors for survival. Conclusions: The ETA is safe and feasible in selected patients with sinonasal tumor invading the anterior skull base. Tumor residual and recurrence are independent prognostic factors for survival.

Objective: To evaluate the value of Hadad-Bassagasteguy flap (HBF) in endoscopic endonasal approaches (EEA) skull base reconstruction by radioanatomic measurements on CT of the skull base of Chinese adults. The following data in terms of anterior skull base defect and reconstruction, sphenoid platform area and middle skull base defect and reconstruction including sphenoid platform and sella area, clivus area defect and reconstruction, and HBF were collected and assessed. Methods: CT image data of 42 Chinese adults were selected to obtain radioanatomic measurement data related to HBF, anterior skull base defect and reconstruction, middle skull base defect and reconstruction, and defect and reconstruction of clivus area. SPSS 26.0 software was used to analyze the data. Results: The radioanatomic measurement data about HBF and skull base of 42 Chinese adults were obtained. The width of the leading edge of HBF [(37.49±2.86) mm] was 6 mm more than the anterior skull base width at the level of the anterior ethmoidal artery [(30.87±8.61) mm], and the width of the trailing edge of HBF [(42.61±3.95) mm] was also 6 mm more than the anterior skull base width at the level of the sphenoethmoidal junction [(26.79±2.79) mm]. The total length of HBF including the pedicle [(79.68±4.96) mm] was 6 mm more than the length of the anterior skull base reconstruction [(54.06±8.67) mm], and the length of HBF without pedicle [(46.27±3.14)] mm was 6 mm more than the length of anterior skull base defect [(30.87±8.61) mm]. The trailing edge width was 6 mm more than the planum sphenoidal width at the level of the optic strut [(30.87±8.61) mm]. The total length of HBF including the pedicle was 6 mm more than the length of the planum sphenoidal, and the sella reconstruction [(64.44±10.25) mm], also was 6 mm more than the length of the planum sphenoidal reconstruction [(73.61±8.28) mm]. The length of HBF without pedicle was 6 mm more than the length of the planum sphenoidal, and the sella defect [(27.88±3.74) mm], also was 6 mm more than the length of the planum sphenoidal defect [(15.50±3.38) mm]. The width of the leading edge of HBF and the width of the trailing edge were both 6 mm more than the width of clivus reconstruction at the level of the foramen lacerum [(21.68±2.30) mm]. The total length of HBF including pedicles was 6 mm more than the clivus reconstruction length [(67.09±5.44) mm], while the length of HBF without pedicles was also 6 mm more than the clivus defect length [(37.19±3.80) mm]. Conclusions: In this study, the radiosanatomic measurements ensured that HBF could provide sufficient tissue flap for the reconstruction of the anterior skull base and sphenoid plateau and extend the reconstruction area to sella and clivus. Preoperative radiosanatomic measurement can be used to predict the size of HBF required for skull base reconstruction, which provides important guidance for flap harvest.
