The best outcome after endoscopic sphenoethmoidectomy follows frequent in-office endoscopic debridement of all crusts and old blood until healing is complete.
Endoscopic sinus surgery (ESS) has become the standard of care in the surgical management of chronic sinusitis over the last 2 decades. This has been due, in large part, to the careful introduction of its technique to otolaryngology by such pioneers as Messerklinger, Stammberger, Kennedy, and others. Traditional surgical approaches were devised around the concept of removing irreversibly diseased mucosa. In recent years, there has been recognition that denuded bone results in delayed healing.1.
