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.

With the advancement of rigid endoscopic nasal surgery techniques, the indications for surgery have continued to expand, encompassing an increasing number of anatomical regions. As a surgical adjunct, imaging-guided system assists surgeons in identifying vital structures and mitigating surgical risks, and they are extensively employed in operations involving the nasal cavity, sinuses, and skull base. Nevertheless, existing imaging-guided system faces several unresolved challenges. With ongoing technological advancements and the integration of novel technologies, these systems are demonstrating renewed vigor.

Extraskeletal Ewing's sarcoma（EES） in the head and neck is extremely rare, with non-specific clinical manifestations, high malignancy, easy recurrence and metastasis, and poor prognosis. This paper reports a case of EES of the parapharyngeal skull base presenting with secretory otitis media as the initial symptom.The treatment consisted of surgery, chemotherapy and radiotherapy. No further metastasis or recurrence was observed during the two years and six months follow-up. Now we reviewed the relevant literatures and summarized the experience of diagnosis and treatment in EES.

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 observe the clinical efficacy of acupuncture of revised acupoint combination around the skull base in treating post-stroke mild cognitive impairment (PSMCI), and preliminary explore its action mechanism. METHODS: A total of 76 PSMCI patients were randomly divided into an observation group (38 cases, 4 cases dropped off) and a control group (38 cases, 3 cases dropped off, 1 case was removed). In the observation group, acupuncture of revised acupoint combination around the skull base (bilateral Fengchi [GB 20], Wangu [GB 12], Tianzhu [BL 10] and Yamen [GV 15], Baihui [GV 20]) was used for treatment. In the control group, 8 non-meridian and non-acupoint points at the distal end were selected for shallow puncture treatment. Retaining the needles of 30 min, once every other day,3 times a week for 4 weeks in both groups. The scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Barthel index (BI) and serum levels of cystatin C (Cys-C) and homocysteine (Hcy) were compared in the two groups before and after treatment, and the clinical efficacy was evaluated. RESULTS: After treatment, the scores of MoCA were increased compared with those before treatment in the two groups (P<0.05), and the score in the observation group was higher than that in the control group (P<0.05). The scores of MMSE and BI were increased compared with those before treatment in the observation group (P<0.05), and the score of MMSE in the observation group was higher than that in the control group (P<0.05). After treatment, the serum levels of Cys-C and Hcy were decreased compared with those before treatment in the observation group (P<0.05), and lower than those in the control group (P<0.05). After treatment, the serum level of Cys-C was increased compared with that before treatment in the control group (P<0.05). The total effective rate of the observation group was 88.2% (30/34), which was higher than 32.4% (11/34) of the control group (P<0.05). CONCLUSION Acupuncture of revised acupoint combination around the skull base can improve cognitive function and daily living ability of PSMCI patients, which may be related to the down regulation of serum levels of Cys-C and Hcy.
