Objective: To explore strategies for preserving facial nerve function during surgeries for rare tumors of the internal auditory canal. Methods: A total of 235 cases of internal auditory canal tumors treated between 2010 and 2023 were included, encompassing vestibular schwannomas, cavernous hemangiomas, meningiomas, and other rare tumors. Various data, including clinical presentations, imaging classifications, and treatment processes, were meticulously analyzed to delineate the characteristics of rare tumors and assess pre-and postoperative facial nerve function. Results: Among all internal auditory canal tumors, vestibular schwannomas accounted for 91.9%. In rare tumors, facial nerve schwannomas constituted 5.3%, cavernous hemangiomas 26.3%, meningiomas 15.8%, and arterial aneurysms 10.5%. Significantly, patients with cavernous hemangiomas displayed pronounced invasion of the facial nerve by the tumor, in contrast to other tumor types where clear boundaries with the facial nerve were maintained. During surgery, individualized approaches and strategies for facial nerve protection were implemented for different tumor types, involving intraoperative dissection, tumor excision, and facial nerve reconstruction. Conclusion: Preservation of the facial nerve is crucial in the surgical management of rare tumors of the internal auditory canal. Accurate preoperative diagnosis, appropriate timing of surgery, selective surgical approaches, and meticulous intraoperative techniques can maximize the protection of facial nerve function. Personalized treatment plans and strategies for facial nerve functional reconstruction are anticipated to enhance surgical success rates, reduce the risk of postoperative facial nerve dysfunction, and ultimately improve the quality of life for patients., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.)

Objective: To evaluate the perioperative analgesic effects of parecoxib sodium in patients undergoing nasal endoscopic surgery., Method: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): A group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by saline at the same volume every 24 h for 48 h; B group received parecoxib at a dose of 40 mg by muscle injection 30 min before the operation followed by 40 mg every 24 h for 48 h; C group received an equal volume of 0.9% saline at the same time points. Patients were assessed with respect to pain score (VAS), rescue analgesia requirement and the side effects during the operation as well as at 3, 24, 48 h after the surgery., Result: Intra-operative as well as the postoperative pain scores were less in the A group and B group than in the.control group. Compared with group A, group B had significantly lower VAS score at 24 h after the operation, however there were no significant difference on other time points. Fewer participants of both the A and B groups required rescue medication after operation., Conclusion: Administration of parecoxib can provide ideal analgesic effects without serious adverse side effects at the perioperative period for patients who received nasal endoscopic operation. Intramuscular parecoxib (40 mg 30 min before the operation followed 40 mg qd for 48 h) designed as preoperative analgesia mode resulted in sufficient perioperative analgesia that deserves popularization in the clinical works.

Objective: To evaluate the preemptive analgesia effects of both the parecoxib sodium and the pentazocine in patients undergoing nasal endoscopic surgery., Method: In the randomized, double blind, controlled study, 120 patients undergoing septoplasty were divided into 3 groups (n = 40): group A received parecoxib 40 mg by muscle injection 30 min before the operation; group B received pentazocine 30 mg; group C received an equal volume of saline. The preemptive analgesia effect was evaluated with VAS scores which recorded at different time points. The proportion of participants using rescue analgesia after the operation were recorded as additional measures of preemptive analgesia., Result: Intra-operative as well as the postoperative pain scores were less in the group A and group B than in the control group. Fewer participants required rescue medication after operation with parecoxib as well as pentazocine than placebo. However there were no difference in the preemptive effects between the group A and group B., Conclusion: Administration of both the parecoxib and pentazocine before the nasal endoscopic surgery can provide preemptive analgesia without serious adverse side effects that deserves popularization in the clinic.
