The CO2 laser has been used in medicine for nearly three decades. Although it had many advantages in the field of oral and maxillofacial surgery, it had limited applications because of its bulky articulated-arm delivery system and so on. Recent improvements such as new flexible fibers and tiny handpieces, however, now allow easy access to any part of the mouth. Nowadays we pay attention to its excellent hemostasis and non-contact surgery in the management of patients with infectious diseases. For the purpose of progressing clinical applications, open and closed wounds which were intended to mimic those produced in clinical oral surgery were created by CO2 laser at rabbit tongue. Then macroscopic and histopathological observations were performed on the healing process of these wounds. And moreover they were compared with scalpel wounds. The results were as follows. Although laser wounds heal slower than scalpel wounds, there is no essential difference in healing process. There is also no difference in the healing process detween open and closed wounds even if the tissue damage extends to the muscle layer.
