LASER-ASSISTED TREATMENT OF PACHYONYCHIA CONGENITA

Abstract:

A method for controlled ablation of target tissue includes activating laser ablation of hyperkeratotic tissue upon detecting a trigger input signal, detecting a photo-acoustical signature due to the laser ablation of the hyperkeratotic tissue, detecting a change in the photo-acoustical signature due to the laser ablation of a material different than the hyperkeratotic tissue, and ceasing the laser ablation upon detecting, by a signal processor, the change in the photo-acoustical signature.
