Background and Objective: Innovations in lasers, light and radiofrequency devices have allowed for improved therapeutic efficacy and safety and the ability to treat patients with an ever-increasing number of medical and aesthetic indications. Safety remains a primary concern and the timely communication of complications and their management is vital to insure that treatments be as safe as possible. The purpose of this report on the Proceedings of the First International Laser Surgery Morbidity Meeting is to provide laser experts the opportunity to present and discuss complications that their patients have experienced and how they were successfully managed. Methods: Laser experts were invited to present complications of laser, light, and radiofrequency treatments that their patients have experienced and to discuss the potential mechanisms leading to the complications their management and final outcomes. Results: Nineteen unique cases are presented and the clinical management of each case discussed. Eighteen sets of pre-and post-operative photos are presented. Conclusion: This report shows that even experts, with extensive experience using light-based therapies, can and do have patients who develop complications. Sound clinical judgment, and knowing how to avoid complications and their timely post-operative management, is essential to insure optimal therapeutic outcome.
Laser epilation of the natal cleft should be considered a first choice treatment for recurrent pilonidal disease. Preventive laser epilation of the natal cleft in patients with recurrent folliculitis could avoid future surgery.
BACKGROUND. Pilonidal disease is a chronic disease of the natal cleft. Recurrent follicular infection is the causative factor. Surgical treatment has a significant failure rate, and recurrence is common. Laser removal of hair in the natal cleft could be an alternative to surgery. OBJECTIVE. To determine the effectiveness of laser hair removal in the natal cleft on pilonidal disease. METHODS. Six young men with recurrent pilonidal disease were treated with laser epilation in our clinic from 2000 to 2003. Most patients had a history of one or more surgical treatments in the area, and all patients had suffered recurrent folliculitis for years. An alexandrite laser was mostly used, although, occasionally, an intense pulsed light device was used. The number of epilation treatments ranged from 3 to 11, performed at 6-to 8-week intervals. RESULTS. All patients experienced progressive resolution of the folliculitis with the laser epilation treatments. No more surgical treatments have been needed. The treatments were simple and quick, and there were no complications. CONCLUSION. Laser epilation of the natal cleft should be considered a first choice treatment for recurrent pilonidal disease. Preventive laser epilation of the natal cleft in patients with recurrent folliculitis could avoid future surgery.
Persistent urticaria is a rare side effect of laser epilation. Rupture of the hair follicle by laser heat may trigger a delayed hypersensitivity reaction in a subset of predisposed allergic patients. An antigen from the disrupted hair follicle may be the triggering factor. To prevent this side effect, we recommend that laser epilation in allergic patients be preceded by an extended laser patch test, which should be evaluated 24-48 hours later. Preventive prednisone should be prescribed to patients who develop an urticarial rash on the test area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
