“…6 Other risk factors include prolonged endotracheal intubation, prolonged head immobilization, and intraoperative Trendelenburg position. 1,[3][4][5]7,8 However, none of these factors was observed in our patient. To our knowledge, there are only 2 reports of similar cases of PPA after an aesthetic plastic surgery operation: 1 after reduction mammaplasty 6 and the other after synchronous 1-sided reduction mammaplasty and 1-sided mastopexy.…”

Scarring alopecia in neonates as a consequence of hypoxaemia-hypoperfusion.

“…Adults who experience immobilisation of the head for 24 hours or longer develop not only occipital ulceration but also scarring.4 5 The duration of exposure to pressure and shearing forces that leads to localised ischaemia appears to determine whether ulceration will be temporary or progress to permanent alopecia in this population.5 6 Comparable data are not available for paediatric or neonatal patients.…”

Postoperative permanent pressure alopecia
