E-026 Around the blind corner of the mouth: a glide-scope directed access to oropharyngeal venolymphatic malformations

Introduction/Purpose Low flow vascular malformations can present anywhere in the body with high prevalence in the head and neck region. Locations in the oropharynx at the base of the tongue or peritonsillar space can complicate percutaneous sclerosant application for minimally invasive treatment of symptomatic lesions. Both anterior transfacial and posterior transcondylar approaches can be limited by a small working window of access to the lesion with potential high risk complication to adjacent surrounding sensitive organs and major vasculatures. Thus, limited visibility for direct percutaneous access into low flow vascular malformation in the oropharynx may exclude a large population of patients to an alternative option to treatment other than surgery. Thus, the purpose of our study is to describe a novel approach using the Glide-Scope, a commonly use device during difficult airway intubation, for access into otherwise difficult and often out of reach low flow vascular malformation in the oropharyngeal space. Materials/Methods Single center retrospective review of 4 cases of oropharyngeal venolympathic malformation, 3 of which utilized a combined Glide-Scope directed and fluoroscopic guided sclerotherapy technique while the remaining were performed via the transfacial or transcondylar approach. Results Please see table 1. Conclusion Symptomatic low flow oropharyngeal vascular malformations can can be technically challenge during initial access for percutaneous sclerotherapy. Our single center retrospective experience reviewed 4 cases, 3 of which were via a novel approach in gaining direct access into oropharyngeal venolymphatic malformations utilizing a video assisted Glide-Scope. We demonstrate high technical success, reduced fluoroscopic and procedural time, and excellent patient response. Disclosures T. Le: None. T. Akinpelu: None. D. Hallam: None. S. Vaidya: None. B.
