Objective:To compare the outcomes of simultaneous versus staged nasal bone reduction and septoplasty in the treatment of traumatic nasal bone fractures with associated septal fractures. Methods:Patients with traumatic nasal bone fractures, with or without septal fractures, were recruited from two hospitals and divided into three groups. Group A underwent simultaneous nasal bone reduction and septoplasty, Group B underwent staged nasal bone reduction and septoplasty, and Group C underwent nasal bone reduction only. Nasal appearance scores and nasal congestion Visual Analogue Scale （VAS） scores were measured preoperatively, at 2 weeks postoperatively, and at 3 months postoperatively. For Group B, scores were also recorded at 2 weeks and 3 months after the second-stage surgery. Differences were analyzed using statistical software. Results:Two weeks post-surgery, the nasal appearance scores significantly decreased in all three groups compared to preoperative scores （P< 0.01）, with no statistically significant differences between the groups （P= 0.43, 0.71, 0.58）. In Group A, the VAS score for nasal congestion decreased significantly following simultaneous surgery （P<0.01）. In Group B, there were no significant differences in nasal congestion VAS scores between pre-surgery and post-first-stage, nor between three months post-first-stage and two weeks post-first-stage （P= 0.61, 0.13）. However, the VAS scores significantly decreased after the second-stage surgery compared to pre-surgery, and three months post-second-stage surgery compared to three months post-first-stage surgery （P<0.01）. The VAS scores for nasal congestion at two weeks post-surgery in Group A were lower than those in Group B after the first-stage surgery （P<0.01）. The incidence rates of nasal adhesions post-surgery in Groups A, B, and C were 0%, 6.9%, and 4.3%, respectively. Conclusion:For traumatic nasal bone fractures with associated septal fractures, performing simultaneous nasal bone reduction and septoplasty under general anesthesia using endoscopy is more time-efficient compared to staged surgery, and it results in a lower occurrence rate of post-surgical nasal adhesions.

Objective:To investigate the clinical diagnosis and treatment of IgG4-related disease（IgG4-RD） primarily involving the nasal cavity and skull base. Methods:A retrospective analysis was conducted on the clinical data of 8 patients with IgG4-RD primarily involving the nasal cavity and skull base who visited the Nasal and Skull Base Surgery Department at Xiangya Hospital from October 2017 to January 2024. The cohort comprised 4 males and 4 females, aged 8 to 69 years. Clinical data, laboratory examination results, imaging findings, histopathological results, and treatment plans were collected. The clinical manifestations, diagnosis, treatment and follow-up results of IgG4-RD primarily involving nasal cavity and skull base were summarized and previous literature were also reviewed. Results:The initial symptoms in the 8 patients included nasal congestion, headache, sensory function decline, and facial deformities. Three patients also had parotid and pulmonary involvement. Among the 8 patients, 4 underwent partial surgical resection combined with glucocorticoid therapy; 1 underwent partial surgical resection combined with glucocorticoid and immunosuppressant therapy; 1 received glucocorticoid therapy alone; and 2 received glucocorticoid combined with immunosuppressant therapy. Follow-up was conducted one month after treatment, lasting from 5 to 79 months. During the follow-up period, recurrence was observed in 1 patient treated with glucocorticoid combined with immunosuppressants and in 1 patient treated with glucocorticoid alone, while the other 6 patients achieved significant remission. Conclusion:The diagnosis of nasal cavity and skull base IgG4-RD requires the combination of histopathology, laboratory tests, and imaging results. Treatment primarily includes glucocorticoids or combined immunosuppressants. For patients with significant compression symptoms, sensory function impairment, or facial deformities, surgical resection is an important treatment option. Given the high risk of recurrence, early intervention, active treatment, and long-term follow-up are crucial.

OBJECTIVE: To explore the clinical application value of mineralized collagen (MC) bone scaffolds in repairing various types of skull defects, and to assess the suitability and repair effectiveness of porous MC (pMC) scaffolds, compact MC (cMC) scaffolds, and biphasic MC composite (bMC) scaffolds. METHODS: A retrospective analysis was conducted on the clinical data of 105 patients who underwent skull defect repair with pMC, cMC, or bMC between October 2014 and April 2022. The cohort included 63 males and 42 females, ranging in age from 3 months to 55 years, with a median age of 22.7 years. Causes of defects included craniectomy after traumatic surgery in 37 cases, craniotomy in 58 cases, tumor recurrence or intracranial hemorrhage surgery in 10 cases. Appropriate MC scaffolds were selected based on the patient's skull defect size and age: 58 patients with defects <3 cm² underwent skull repair with pMC (pMC group), 45 patients with defects ≥3 cm² and aged ≥5 years underwent skull repair with cMC (cMC group), and 2 patients with defects ≥3 cm² and aged <5 years underwent skull repair with bMC (bMC group). Postoperative clinical follow-up and imaging examinations were conducted to evaluate bone regeneration, the biocompatibility of the repair materials, and the occurrence of complications. RESULTS: All 105 patients were followed up 3-24 months, with an average of 13 months. No material-related complication occurred in any patient, including skin and subcutaneous tissue infection, excessive ossification, and rejection. CT scans at 6 months postoperatively showed bone growth in all patients, and CT scans at 12 months postoperatively showed complete or near-complete resolution of bone defects in all patients, with 58 cases repaired in the pMC group. The CT values of the defect site and the contralateral normal skull bone in the pMC group at 12 months postoperatively were (1 123.74±93.64) HU and (1 128.14±92.57) HU, respectively, with no significant difference ( t=0.261, P=0.795). CONCLUSION MC exhibits good biocompatibility and osteogenic induction ability in skull defect repair. pMC is suitable for repairing small defects, cMC is suitable for repairing large defects, and bMC is suitable for repairing pediatric skull defects.

Objective:To explore the surgical techniques and clinical outcomes of endoscopic transnasal approaches in the treatment of skull base chondrosarcomas. Methods:Data from patients diagnosed with skull base chondrosarcomas and treated via endoscopic transnasal surgery at the Department of Otorhinolaryngology and Head and Neck Surgery, Xuanwu Hospital, Capital Medical University, from 2013 to 2022 were collected. This retrospective study analyzed the patients' clinical presentations, histopathological grading, involved sites and extents, and complications following the endoscopic transnasal surgery. Disease-free survival rates were calculated using the Kaplan-Meier method. Results:Complete data from 31 patients showed that the primary tumor site was in the petroclival region in 27 cases（87%）, and the anterior skull base in 4 cases（13%）. Pathological grades were Grade Ⅰ（12 cases）, Grade Ⅱ（16 cases）, and Grade Ⅲ（3 cases）. Total resection was achieved in 25 cases, with residual disease post-surgery in 6 cases. The average follow-up duration was 35.7 months（ranging from 6 to 120 months）. Among those who achieved complete resection, recurrence occurred in 5 cases（5/25）, with a five-year disease-free survival rate of 80%. Postoperative complications included transient abducens nerve palsy in 6 patients and cerebrospinal fluid rhinorrhea in 4 patients. There were no cases of death or permanent cranial nerve palsy. Total resection rate（P=0.001） and involvement of the cerebellopontine angle and jugular foramen（P=0.037） were identified as independent risk factors for residual disease and recurrence of chondrosarcoma. Conclusion:The endoscopic transnasal approach is a safe and feasible treatment option for skull base chondrosarcomas.

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.
