Abstract:
Advantages of transcanalicular laser-assisted dacryocystorhinostomy (TCDCR) over conventional, external, and endonasal dacryocystorhinostomy (DCR) have been purported to include decreased operating time, reduced morbidity, enhanced cosmesis, avoidance of general anesthesia, and a shorter recovery time. However, 1 case of skin necrosis has recently been reported to have occurred following diode laser-assisted TCDCR, and the authors now report 3 additional cases that were evaluated by the Ophthalmic Plastic Surgery services at the University of North Carolina, North Carolina, and the University of California, San Francisco. Three patients developed full-thickness tissue necrosis over the medial canthus following TCDCR, and 2 of these patients experienced persistent tissue breakdown at the site following reconstructive repair.

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
