目的神经内镜下经鼻蝶窦入路术中能够直视肿瘤、无脑组织牵拉,已广泛应用于垂体腺瘤的手术治疗,而扩大经鼻蝶窦入路突破了传统的限制,提高了鞍上肿瘤及海绵窦区域肿瘤的切除率。神经内镜下扩大经鼻蝶窦入路治疗颅咽管瘤的安全性及有效性是目前关注的重点。方法回顾性分析20例颅咽管瘤患者的临床资料,均在神经内镜下行扩大经鼻蝶窦入路鞍区病变切除,结合国内外该入路治疗颅咽管瘤的文献进行讨论。结果20例均实现肿瘤全切除,无死亡病例。15例无任何并发症,4例出现1项并发症,1例出现2项并发症。仅1例术后新发视力、视野损伤;2例新发一过性尿崩;2例出现新发垂体功能减退;2例术中保留垂体柄,垂体功能并未见明显变化;2例术后感染,予抗生素治疗控制良好。术后随访:2例在术后8、18个月垂体核磁示可疑复发,其余最长随诊时间12个月复查时没有任何复发迹象。保留垂体柄的患者术后7个月的随访过程中未出现复发。结论神经内镜下扩大经鼻蝶窦入路切除颅咽管瘤的安全性、有效性均比较乐观。颅底重建技术的发展极大降低术后脑脊液漏发生率,为手术提供了支持与保障。 相似文献

颅咽管瘤是一种少见的颅内良性肿瘤,占颅内原发件肿瘤的1%~3%,手术是治疗此肿瘤的首选方法。以往采取经颅或经蝶入路显做镜下切除肿瘤,近年来随着颅底内镜外科技术的发展,有学者应用内镜经鼻蝶鞍膈上入路进行鞍上池、鞍区和第三脑室颅咽管瘤切除,取得了较好的手术效果,但后颅窝斜坡区颅咽管瘤是否适合经鼻内镜手术切除?目前少见文献报道。近期我们应用内镜采取鼻中隔经蝶入路的手术方法切除1例后颅窝斜坡区颅咽管瘤并获得成功。现就此病例的手术方法,手术中注意事项进行探讨。 相似文献

Approaches to sella turcica in endoscopic pituitary surgery 总被引:6,自引:0,他引:6
Recent advances in endoscopic sinus surgery suggested the potential for its surgical application to pituitary surgery. A number of institutions have reported the advantage of endoscope use in pituitary surgery, which is now widely accepted, but approaches to the sella vary in the literature. We retrospectively studied sella approaches in endoscopic pituitary surgery as rhinologists. Subjects included 6 cases of pituitary adenoma and 2 cases of Rathke's cleft cyst. A both-nostril transnasal transsphenoidal approach, our standard technique, was used in 6 cases. This approach consisted of elevation of mucoperiosteal flaps, resection of the vomer and sphenoid anterior wall, and opening of the sellar floor. Elevated mucoperiosteal flaps were used to close of the sella after tumor resection. All tumors were removed and no significant postoperative complications occurred. We found the both-nostril transnasal approach to be easy and time-saving and provided surgeon with a broad surgical field necessary to treat large tumors and accidental cases. Postoperative observation of the sella was easy for wide opening of the anterior wall of the sphenoid sinus. In our experience with reoperation, we quickly accessed the sella and easily removed tumors in the second operation. Our technique therefore has an advance in treatment of recurrence. The both-nostril transnasal approach involves the same procedures as median drainage of the sphenoid sinus, so our technique may have advantages in preventing mucocele of the sphenoid sinus as a late complication of transsphenoidal surgery. The transnasal transsphenoidal approach via both nostrils is preferable rhinologically. 相似文献

BACKGROUND: The aim of this study was to discuss the use of nasal irrigation and suction systems in endoscopic pituitary surgery to examine the sella and facilitate tumor removal. We describe a new technique of sellar exploration. METHODS: Following the endoscopic approach to the pituitary by the otolaryngology team, pituitary masses are resected. Then, the ClearESS nasal irrigation and suction system is used by the otolaryngology team to visualize the sella ("hydroscopy"). The combination of this ClearESS technology and angled endoscopes is used to scrutinize previously inaccessible areas of the tumor bed. RESULTS: Over 50 patients have undergone minimally invasive pituitary surgery via the endoscopic approach with postresection hydroscopy of the sella. The use of angled endoscopes in combination with the ClearESS technology greatly increased visualization of the sella, thereby facilitating complete tumor removal. There have been no complications associated with the use of hydroscopy. CONCLUSION: The use of angled endoscopes in conjunction with hydroscopy increases visualization of the sella. The otolaryngologist plays a critical role in this examination with manipulation of the angled endoscopes. Therefore, the role of the otolaryngologist is extended beyond the approach to the pituitary. 相似文献

Assessment of the efficacy of endoscopy in pituitary adenoma resection 总被引:13,自引:0,他引:13

OBJECTIVE: To obtain objective evidence that the use of endoscopy in the surgical management of pituitary tumors improves intraoperative visualization and significantly impacts operative outcomes. DESIGN: Case series of pituitary adenomas treated surgically by endoscope-assisted microscopic resection. SETTING: University-affiliated tertiary care medical center. PATIENTS: Consecutive sample of 9 patients referred for surgical management of pituitary adenoma. INTERVENTIONS: Each patient underwent transseptal transsphenoidal microscopic tumor resection. The procedure was modified by the use of intrasellar endoscopy as an adjunctive imaging modality. Following complete microscopic resection of tumor, rigid 0 degrees and 30 degrees 4.0-mm endoscopes were used to conduct a final survey of the sellar and parasellar spaces. Residual tumor fragments identified during this endoscopic examination were removed. OUTCOME MEASURES: Endoscopes were thought to have a significant impact on surgical therapy in cases where residual tumor that was not detected microscopically was identified and removed during endoscopic examination. Analysis of each case included correlation between intraoperative findings and retrospective review of dictated operative reports and intraoperative videotape. RESULTS: Three of the patients with macroadenoma (33% of total, 43% of macroadenoma cases) had tumor fragments that were only identified and removed endoscopically. CONCLUSIONS: Endoscopy provides distinct advantages over microscopy in imaging intrasellar and parasellar structures during pituitary tumor resection. These data support the numerous anecdotal accounts of the usefulness of pituitary endoscopy and are consistent with the small amount of objective evidence offered on the subject.

Staged endoscopic operation for large pituitary adenomas 总被引:6,自引:0,他引:6
The advantages of endoscopic transnasal pituitary surgery include a panoramic view of the area and easy reoperation. Based on this, we performed a planned staged operation in two cases of large pituitary adenomas, extending to the suprasellar lesion, using the endoscopic transnasal trans-sphenoidal approach via both nostrils. In the initial operation, a tumour mass was from the intrasellar region, however, that part of it in contact with the tumour capsule was left intact for prevention of peri-operative injury. The residual mass descended into the sellar floor at the second operation, and was easily resected with no complications. A staged operation by the endoscopic transnasal approach, although it requires two operations, is thought to be a safe and efficient procedure for the removal of large pituitary tumours. 相似文献
