title: Sellar reconstruction: is it necessary?
abstract: BACKGROUND
  Sellar reconstruction is practiced routinely during the transsphenoidal approach to pituitary tumor resection. This practice exposes the patient to risks of donor site complications and may interfere with measuring postoperative tumor reduction. We propose that it is not a necessary component of transsphenoidal pituitary surgery in the absence of intraoperative cerebrospinal fluid (CSF) leak.
  
  
  METHODS
  A retrospective chart review of 45 cases of minimally invasive pituitary surgery were reviewed. Twenty-eight cases were identified with no sellar reconstruction being performed. Age, sex, revision surgery, postoperative CSF leak, days with lumbar drain, meningitis, ophthalmoplegia, visual acuity loss, postoperative epistaxis, diabetes insipidus, development of empty sella syndrome, and length of stay were investigated in these cases.
  
  
  RESULTS
  Twenty-three cases were the primary procedure and five cases were revision surgery. Complication rates were low and compared favorably with those reported in the literature. Five cases of transient diabetes insipidus occurred. There was one postoperative CSF leak that required 4 days with a lumbar drain. No cases of empty sella syndrome developed. There were no cases of meningitis. The average length of stay was 2.9 days.
  
  
  CONCLUSIONS
  Sellar reconstruction during transsphenoidal approach to pituitary tumor resection is not required for patients without evidence of an intraoperative CSF leak. This practice exposes the patient to the risks of donor site complications without reducing the rate of postoperative complications.
