This study shows that a low-level GaAlAs (λ:810 nm; P, 200 mW) laser hastens new bone formation only in the early stages of the consolidation period in distraction osteogenesis, and has no significant effect in later stages.

Juvenile hyaline fibromatosis (JHF) is an unknown hereditary disorder with variable penetrance. The characterizations of this disease consist of different signs and symptoms such as multiple tumorous (tumor-like) muco-cutaneous proliferation, gingival hypertrophy, perianal lesions, articular contractures, and osteolytic lesions. A 3-year-old girl with numerous painless nodular masses on her gingival, ear and anal areas is presented in this case report. Based on characteristic histological features, the diagnosis of JHF was made. The patient underwent surgery following general anesthesia and the above areas were surgically operated with appropriate laser parameters, and the patient was able to eat and wash away after a day and was discharged with an antibiotic prescription after one day in the hospital and returned to normal after a week. The recurrence occurred in other areas a year later, especially in the cheek, the ears and the anal area. Therefore, this rare case is presented with recurrence.
