Endoscopic Sinus Surgery
Necrotic tissues were endoscopically debrided until macroscopically
healthy bleeding margins were reached. Patients were taken back to the
operating room for further debridement whenever suspicion for continued
infection remained. Of note, a more aggressive surgical approach was
adopted in the latter years of the study, including endoscopic resection
of the anterior skull base, clivus, pterygopalatine fossa and
infratemporal fossa whenever these sites were involved.
