Objective:To review indications and techniques for the endoscopic endonasal approach to the craniovertebral junction(CVJ),analyze postoperative outcomes,and discuss important technical considerations.Methods:A 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 followup were recorded.Results:There 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,5e75 years),with 18 females and 12 males.The majority of patients(n Z 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,0e8 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 0e3 days),with 85%extubated by postoperative day 1.A tracheotomy was required in one patient.Conclusion:The endonasal endoscopic approach is a valuable technique for access to the CVJ with minimal disruption of respiratory and alimentary function.
