دراسة استعمال الليزر في طب الامراض الجلدية (تقرحات الجلد - ثاليل - الوشم - الوحمة)

This research studies the evaluation of laser diode (GaAlAs) efficiency through observing the effects of the wave length of ('()M '*))nm in the treatment of some dermalogical diseases and the follow up of such pathological cases during the treatment period and the improvement of attaining the recovery state. As a primary study, first we tused (a sheep's tongue) and this is exposed to laser radiation with different powers and with different periods to observe the effect of the radiation (pulsing or continious) falling on the tongue, the extent of the depth effect through the tissue is also registered. A suitable power of ((W) is also chosen with a direct use of the optical fiber, with a pulse time ((sec-pulse) and with an interval period ((sec-pulsing). The results has been positive through the finding of the suitable depth of permeating the skin with no negative effect on the surrounding tissue. A group of patients of different ages (males),(females) has been chosen for the following pathological cases (removing the wart, the tattoos and the ( Superficial lymphatic malformation, Lobular capillary hemangioma ) as the pathological cases have been treated by the traditional medical ways (by using chemical -the electric( cautery) Some undesirable dermal side effects have been noticed together with recurrence of the disease of the same type of sickness after a period of time. The treatment has been carried out in the operation department of Ear, Nose and Throat (E.N.T.) in a specialized hospital for surgery with the use of positional anesthetization. As a follow up, the cases have been then examined after ((week, *weeks, J moth, month) and the study lasted for L months and more. The elimination (removing) has been carried out with the use of the optical fiber of laser radiation starting from the terminals sliding into the middle in a circular way and with a pulse mode. The elimination has been easy and complete. The results have been good with the use of the Diodelaser (GaAlAs) by as a good response to the treatment eliminatioa of diseases and unrecurrence of the diseases also the scantiness of the damaging of the treated area. No bleeding is found in the treated area. We register the recovery rate, recovery period and the diseases recurrence rate . an‎d comparison has been made with the cases treated by the traditional way, we noticed the recurrence of the diseases in traditional therapy .
