abstract: OBJECTIVE
  To evaluate the effectiveness of transsphenoidal endoscopic endonasal approach for the surgery of pituitary abscess.
  
  
  METHODS
  Eighteen pathologically diagnosed pituitary abscess were resected through transsphenoidal endoscopic endonasal approach at Tianjing Huanhu hospital between January 2000 and December 2011.Retrospective analysis was done upon clinical presentations and imaging features. There were 6 males and 12 females. The average age was 48.5 years old and the average disease course was 5.8 years. The typical clinical manifestations included headache (13 cases), pituitary dysfunction (10 cases), Diabetes Insipidus (4 cases) visual interference (8 cases) and fever (4 cases). All cases were resected by transsphenoidal endoscopic endonasal approach with general anesthesia. The postoperative symptoms and follow-up results were recorded.
  
  
  RESULTS
  All patients were followed up from 6 months to 6 years. Postoperatively, headache was recovered in 13 cases, visual was improved in 6 cases, hypopituitarism was relieved in 8 cases and polyuria was disappeared in 3 cases. One case was recurrent and cured by transsphenoidal endoscopic endonasal approach.
  
  
  CONCLUSIONS
  Transsphenoidal endoscopic endonasal approach for the surgery of pituitary abscess is effective.
