Abstract
Rhinosinusitis/mucocele are rare complications of transsphenoidal surgery. We present a retrospective analysis of 323 patients who received transsphenoidal surgery for pituitary adenoma. Twenty of the 323 patients (6.2%) developed rhinosinusitis/mucocele after transsphenoidal surgery as shown by MRI. All 20 patients with rhinosinusitis/mucocele occurred in the group who received the small sphenoidotomy approach and simple postoperative nasal care. Medical management was successful in 13 of 20 cases (65%). The remaining seven patients received endoscopic sphenoidotomy. On re-operation, purulent pus was discovered in two, a necrotic fat graft in one, mucocele in one, a dropped tumor in two, and a bone chip in one. Sphenoid sinusitis resolved in all seven cases. The formation of sphenoid sinusitis/mucocele is related to the size of the sphenoidotomy, frequency of postoperative nasal care, and foreign body accumulation. Early surgical drainage is necessary in patients with rhinosinusitis/mucocele refractory to medical management to prevent ascending meningitis.
