Conclusion The sigmoid-incision (S-I) rescue flap technique has the advantage of both reduced-invasiveness and providing a sufficient surgical corridor for endoscopic endonasal skull base surgery (EESBS). Objective Skull base reconstruction with nasoseptal flap (NSF) is critically important in managing post-operative cerebrospinal fluid (CSF) leakage after tumor removal by EESBS. The NSF needs to be elevated before sphenoidotomy and posterior septectomy to preserve the pedicle. However, most extradural surgery without CSF leakage does not require NSF and, therefore, NSF preparation is often futile. As a result, a rescue flap technique to overcome this problem has been developed, whereby a new S-I rescue flap method is used that enables wide exposure of the sphenoidal rostrum and smooth manipulation of surgical instruments to preserve the NSF pedicle. Materials and methods Starting in April 2014, 19 cases underwent EESBS with S-I rescue flap. Results All patients underwent tumor resection under an adequate operative field with smooth manipulation of surgical instruments. Two complications were experienced. One patient had CSF leak after removal of the nasal packing, but the leakage was successfully closed by conventional NSF. Another patient had epistaxis from the septal wall, but this was controlled by electrocautery. 相似文献

Endonasal skull base surgery is growing exponentially as a subspecialty. In recent years, advances in endoscopic techniques and intraoperative navigation systems have allowed us to expand the indications of endoscopic skull base surgery. Major skull base centers worldwide are addressing larger and more complex lesions using endoscopic techniques. As a consequence, the skull base defects are more challenging to reconstruct. In this report, we present a novel technique to reconstruct the denuded septum remaining after the use of the vascular pedicled nasoseptal flap. Laryngoscope, 2010 相似文献

ObjectiveTo review indications and techniques for the endoscopic endonasal approach to the craniovertebral junction (CVJ), analyze postoperative outcomes, and discuss important technical considerations.MethodsA retrospective analysis was performed on all patients undergoing endonasal endoscopic approaches to the CVJ from May 2007 to June 2017. Demographic information, presenting symptoms, imaging results, treatment course, postoperative functional status, and follow-up were recorded.ResultsThere was a total of 30 patients in this series, with a mean follow-up of 11.7 months. The average age was 33.6 years (range, 5–75 years), with 18 females and 12 males. The majority of patients (n = 22, 73.3%) had Chiari malformation type 1 with basilar invagination and symptomatic cervicomedullary compression as the indication for surgery. Intraoperative cerebrospinal fluid leak (CSF) was noted in 3 cases of odontoid resection and a single case of skull base resection. There were no postoperative CSF leaks. Overall, 81% of patients resumed regular diet by post-operative day 2 (range, 0–8 days). Severe postoperative dysphagia occurred in two cases with one requiring gastrostomy tube placement and another utilizing total parenteral nutrition for support prior to eventual gastrostomy. On average, patients were extubated by postoperative day 0.93 (range 0–3 days), with 85% extubated by postoperative day 1. A tracheotomy was required in one patient.ConclusionThe endonasal endoscopic approach is a valuable technique for access to the CVJ with minimal disruption of respiratory and alimentary function. 相似文献
