Aesthetic earlobe remodeling: my personal experience with an LBO laser at 532 nm

Abstract

Since 1960, when Maiman built the first laser equipment, this technology has gone through a continuous development and an increasing utilization in several fields.

Nowadays many pathologies find a less traumatic solution in laser technology.

Laser can be either used to treat lesions with a high bleeding risk such as hemangioma and lymphangioma or in patients with coagulation diseases or hypertension, taking advantage of its capability to coagulate. Moreover healing and scarring are improved by the laser's effect of biostimulation and inhibition of bacterial growth, this leading to a greater comfort for the patient. The tissue vaporization and the dimension of the damaged area depend on several factors, those related to the laser used, such as wavelength, power, emission mode (continued or pulsed mode) and the power density, and those concerning to the treated tissue, like color and consistency. In this Study, we used an Lithium Borate, (LBO), laser, instead of scalpel for earlobe reduction in a 35-year-old male patient with pending lobule. LBO laser works through a solid active medium emitting a visible green light. A diode laser, with a wavelength of 810 nm, stimulates a crystal of Nd:YAG, which has a wavelength of 1064 nm. Then a crystal of LBO doubles the vibration frequency of the photons, leading to a final wavelength of 532 nm.
