Laser in the Treatment of Granulomas on the Nose Produced by Polymethylmethacrylate: A Case Series

The search for aesthetic non-surgical procedures is growing. The use of polymethylmethacrylate (PMMA) as a filling material in the nose represents one of the many options among these aesthetic procedures. Its use, however, can lead to complications. The treatment of these complications is often challenging.

We performed a retrospective clinical analysis of the medical records of patients undergoing treatment of PMMA granulomas of the nose at a private clinic from January, 2015, to January, 2021. A short-pulsed neodymium-YAG (Nd:YAG) laser was applied intranasally or directly by cutaneous incision in the granulomas. Laser-tissue interaction heats the alloplastic material, fragments the product and creates cleavage paths, thereby facilitating the removal of PMMA, either by intercartilaginous removal or aspiration.

Twenty-seven patients were included in the study. All had a history of PMMA injection in the nose. All patients were treated with an intralesional pulsed 1064nm Nd:YAG laser. The material removed after laser-tissue interaction was sent for histopathological examination; this showed the presence of microparticles of exogenous material compatible with PMMA. The partial removal of the alloplastic material was shown to be effective in all cases. One patient developed a small blister in the nasal dorsum. Follow-up ranged from six to 47 months.

The use of intralesional Nd:YAG laser for the treatment of PMMA granulomas on the nose proved to be an effective and safe procedure with improvement of nasal shape, without compromising respiratory function. This technical option represents yet another alternative in the treatment of PMMA granuloma complications. J Drugs Dermatol. 2021;20(11): 1161-1166. doi:10.36849/JDD.6550.
