title: [Diagnosis and treatment of solitary pterygoid benign lesions].
abstract: OBJECTIVE
  To investigate the clinical and pathological features of solitary pterygoid benign lesions, as well as the treatment and outcome of endoscopic surgery.
  
  
  METHODS
  We retrospectively analyzed clinical data of 4 patients with pterygoid benign lesions in our department. High resolution CT and enhanced MRI were performed before the operations, then endoscopic surgeries were carried out under the circumstance of general anesthesia. After a follow-up in 12 months to 48 months, nasal endoscopy and MRI examination were performed. Therefore we are able to understand the situation of operations and postoperative recurrences, and to inquire about the changes of symptoms and the relief of symptoms before and after surgery.
  
  
  RESULTS
  From the Pathological diagnosis, it showed 2 cases of cystic lesions, 1 case of spindle cell lipoma, 1 case of inflammatory lesion. Postoperative follow up showed scar formation, smooth surface, no recurrence, and no new symptom. Nasal obstruction is relieved after the surgery, and no changes in the sympotoms of headache were observed.
  
  
  CONCLUSIONS
  The combination of high resolution CT with enhanced MRI isimportant for ascertaining the location, extent and nature of the pterygoid lesions. Endoscopic surgery is a minimally invasive, safe, and effective method for the treatment of solitary pterygoid benign lesions.
