title: Transcanal endoscopic approach to lesions of the suprageniculate ganglion fossa.
abstract: OBJECTIVE
  The aim of this paper would be to describe the first case series of exclusive transcanal endoscopic approach to treat lesions with limited extension at the suprageniculate fossa. This endoscopic approach allowed a complete removal of suprageniculate disesases with low complication rates using a minimally invasive surgical route.
  
  
  METHODS
  This is a retrospective chart analysis and a surgery video recording review of these patients were performed in August 2015. From November 2011 to November 2015, 29 patients were submitted to an endoscopic transcanal lateral skull base surgery. From those 29 subjects, in 6 patients an exclusive endoscopic transcanal suprageniculate approach was performed to remove lesions located into the geniculate fossa. Surgical indications, pre-operative assessment, results were collected and the surgical technique were described.
  
  
  RESULTS
  The final study group was composed of 6 patients. 3 male and 3 female; median age is 25.3 years old. In all 6 subjects it was possible to remove the lesions using an exclusive endoscopic transcanal suprageniculate approach. No intraoperaoperative complications were observed in any patients. The mean follow up period was 15.16 months.
  
  
  CONCLUSIONS
  Exclusive endoscopic transcanal suprageniculate approach is definitely a minimally invasive technique and should be consider an optimal solution to treat lesions located in the suprageniculate fossa in some patients. We introduce a minimally invasive approach to the geniculate ganglion region in order to allow complete removal of suprageniculate disesases with low complication rates using a minimally invasive surgical route.
