Hyperbaric oxygen in the management of wound tissue necrosis after external dacrocystorhinostomy

Abstract

Hyperbaric oxygen is an adjunctive treatment for promoting wound healing and reducing infection. We present an unusual case of wound tissue necrosis occurring after external dacryocystorhinostomy (ExtDCR) that was subsequently treated with hyperbaric oxygen (HBO) and advancement flaps with good outcome. HBO improves vascularization of ischemic tissues after ExtDCR for greater success after reconstructive surgery.

Effect of hyperbaric oxygenation on random rat skin flaps vascularization

“…The animals were placed in the hyperbaric chamber in accordance with their group. HBO was carried out in an appropriate chamber for animal experimentation developed by the team involved in this research 5 . Prior to pressurization, oxygen injected into the chamber for 5 min displaced the environmental air inside it and allowed for an atmosphere close to 100% oxygen.…”
