Literature Reviews: A New Linear Method for Hair Transplantation and Cutaneous Laser Surgery

In 1997, a review introduced a new linear method for hair transplantation that showed promising results, being equal or superior to traditional methods in terms of graft visibility, hairline naturalness, hair density, and patient satisfaction. This technique allowed for the transplantation of 2000 to 3000 hairs within 2-3 hours, and a patent was pending for the associated punch device. Additionally, the review covered cutaneous laser surgery for various skin conditions and future trends in the field. A specific study with four Caucasian women investigated the penetration depth of the Ultrapulse CO₂ laser, revealing that one pulse affected the epidermis, two pulses removed the entire epidermis, and three pulses reached the papillary dermis, although actual surgical practice would likely involve higher energy and different techniques.
