Как я понял, pinhole method (или pinhole therapy) применяется при удалении рубцов, оставшихся после ожогов. В рубце делают много маленьких, но глубоких отверстий лазером, после чего меняется цвет и строение рубцовой ткани, рубец рассасывается и разглаживается.

Вот английское описание из гугла: «Many patients with burn injuries have various complications and emotional problems due to scars. Although various modalities to improve burn scars have been attempted, such as excision of scars, skin grafts, laser abrasion and silicone product usage, the cosmetic outcomes have not been satisfactory for a large portion of patients. Herein, we describe two cases which showed satisfactory cosmetic results after treatment of burns scars with the pinhole method using a carbon dioxide (CO(2)) laser that allowed us to make deep, closely set holes reaching down to the upper dermis. A 20-year-old female patient with a scar on her neck and a 25-year-old female patient with a scar on her right forearm after burn injuries are presented. As early as only a few weeks after the treatment, the scars showed relaxation of contracture, reduction of wrinkles and improvement of texture and color compared to before the treatment. Treatment of burn scars with the pinhole method can be easily performed and results in dramatic improvement in scar quality with only a few side-effects».
