峡部入路在甲状腺手术中的临床研究

目的探讨甲状腺手术中峡部入路的临床应用。方法将我院2007年8月~2010年8月的229例甲状腺手术患者分为两组。治疗组113例采用峡部入路,对照组116例采用传统入路,均由同一组医生施术。观察记录手术时间、术中出血、术后引流量及术后喉返神经及甲状旁腺损伤情况。结果治疗组在上述观察指标上均优于对照组（P〈0.05）。结论经峡部入路行甲状腺手术可明显缩短手术时间,减少术中出血、术后引流量,降低喉返神经及甲状旁腺损伤的发生率,优于传统甲状腺手术入路。     

Benefits of maxillectomy with internal dissection of the masticator space by transmandibular approach in the surgical management of malignant tumours of the upper gingiva and hard palate: a clinical review of 10 cases

The aim of this study was to review patients with tumours extending to the posterior portion of the upper gingiva and hard palate, and to evaluate the postoperative outcomes. Ten consecutive patients with tumours in the upper gingiva and hard palate, who underwent maxillectomy with internal dissection of the masticator space by the transmandibular approach, were reviewed retrospectively. Among the 10 patients, the pathological diagnosis was squamous cell carcinoma in seven, adenoid cystic carcinoma in one, malignant melanoma in one, and osteosarcoma in one. Loco-regional control was achieved in eight of nine patients (88.9%). Three patients had residual moderate trismus. Cosmetic issues were not noted in any patient. En bloc resection of the maxilla with the internal portion of the masticator space and neck through the parapharyngeal space by the transmandibular approach is a useful and satisfactory technique for the excision of a tumour with involvement of the posterior portion of the upper gingiva and hard palate.     

Compartment syndrome and rhabdomyolysis as a positioning complication following retrosigmoid craniotomy

The goal of surgical positioning is to provide optimal surgical access and visualization while maintaining the patient's safety, with the least physiological compromise. Here, we report a 30-year-old man with an unremarkable past medical history who developed superior vena cava syndrome after a 15-hour retrosigmoid craniotomy for removal of a right cerebellopontine (CP) angle tumor. Compartment syndrome from the head to neck and rhabdomyolysis were recognized, with extensive swelling of his head and neck, markedly swollen soft tissues and necrosis of multiple muscles revealed by computed tomography, and very high concentrations of creatine kinase (CK) and aspartate transaminase. Immediate intensive care and rehabilitation therapy were provided and aimed at maintaining adequate perfusion/oxygenation and decreasing tissue pressure. He was successfully weaned from ventilation on postoperative day (POD) 25, transferred to a general ward on POD 29, and discharged with mild muscular and neurological sequelae on POD 51. Careful adjustment of surgical positioning is crucial for patient safety, especially when positioned at an extreme position in association with prolonged surgery.     

Giant trigeminal schwannoma with parapharyngeal extension: Report of a case

The authors present their experience in the treatment of a giant trigeminal schwannoma with wide extension in the parapharyngeal space using a combination of the orbito-zygomatic and the transcervical-transmandibular approaches. The clinical and radiological findings, advantages of surgical approach and clinical outcome will be discussed.     

天幕脑膜瘤的影像学分型及显微手术治疗

目的 探讨天幕脑膜瘤的影像学分型及手术效果。方法 回顾性分析2018年1月至2019年12月显微手术治疗的31例天幕脑膜瘤的临床资料。按影像学资料分型:前内侧型（Ⅰ型）、前外侧型（Ⅱ型）、内中型（Ⅲ型）、后内侧型（Ⅳ型）、后外侧型（Ⅴ型）；根据肿瘤生长方向分为幕上型、幕下型、幕上下型。依据肿瘤分型选择合适手术入路。结果 31例中，Ⅰ型3例 ，Ⅱ型5例，Ⅲ型3例，Ⅳ型8例，Ⅴ型12例；幕上型6例，幕下型19例，幕上下型6例；Simpson分级Ⅰ级切除23例，Ⅱ级5例，Ⅳ级3例。无手术死亡病例。31例术后随访3~18个月；2例部分切除术后行伽玛刀治疗，复查MRI未见肿瘤增长；1例部分切除术后13个月复查MRI显示肿瘤进展，但无新发症状，动态复查MRI随访观察；所有病人术后均恢复良好，KPS评分≥70分。结论 天幕脑膜瘤手术入路的选择必须依据肿瘤的位置、大小及生长方向综合分析，个体化设计。选择合适的手术入路、熟悉掌握运用局部显微解剖关系、术中尽量避免过度牵拉造成肿瘤周围组织及血管损伤、最大程度减少手术并发症，是取得良好手术效果的关键。
