Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Infectious Disease

Background:

  • Sphenoid sinusitis is a known complication of endoscopic transsphenoidal pituitary surgery.
  • Research on the link between sellar defect reconstruction methods and postoperative sinusitis is limited.

Purpose of the Study:

  • To investigate the incidence of sphenoid sinusitis after pituitary surgery.
  • To identify risk factors and causative pathogens for this complication.

Main Methods:

  • Prospective cohort study of 182 patients with benign pituitary tumors undergoing surgery.
  • Sellar defect reconstruction utilized bone chips.
  • Patients were followed with nasal endoscopy for at least 6 weeks.

Main Results:

  • Postoperative sphenoid sinusitis occurred in 31.3% of patients.
  • Bone chip detachment was a significant risk factor (RR 2.86).
  • Common pathogens included Staphylococcus aureus (MSSA and MRSA) and Pseudomonas aeruginosa.

Conclusions:

  • Regular nasal endoscopy aids in early diagnosis of sphenoid sinusitis.
  • Culture-directed antibiotics and endoscopic debridement are effective treatments.
  • Further development of reconstruction techniques is needed to minimize bone chip detachment.
