Intraoral Styloidectomy Using an Endoscope With Tissue Retractor

The extraoral approach with the risk of facial nerve injury and the visible scar is commonly performed for an elongated styloid process, because intraoral styloidectomy is challenging for the deep and limited surgical field. The authors report minimally invasive intraoral styloidectomy using an endoscope with tissue retractor. A 57-year-old female was referred to our department with a left pharyngeal foreign body sensation and pharyngeal pain after head turning and neck compression. Clinical and radiological diagnosis was an elongated styloid process (Eagle syndrome). Because the styloid process could be palpated intraorally, the patient underwent endoscopically-assisted intraoral styloidectomy without tonsillectomy under general anesthesia as minimally invasive surgery. The styloid process was resected safely with a piezoelectric surgical device under endoscopic guidance. The postoperative course was uneventful without complications.
