Pressure-induced alopecia in pediatric patients following prolonged urological surgeries: The case reports and a review of literature.

Postoperative alopecia has been reported as a rare complication after prolonged immobilization during general anesthesia. The constant pressure on the scalp is causative and may be exacerbated by hypoxemia or hypotension. There is a correlation between the length surgery duration under anesthesia and the development of permanent alopecia. Regular head turning schedules and vigilance for the condition should be used as prophylaxis to prevent permanent alopecia.
