Tympanic injury secondary to positive pressure mask ventillation is rare. During resuscitative procedures, two patients developed partial deafness, one from disarticulation of the incudomalleal joint, the other from an oval window perilymph fistula. Excessive pressure transmitted rapidly through the eustachian tube is postulated to have caused both injuries.
正压面罩通气继发鼓膜损伤罕见。在复苏过程中，两名患者出现部分听力丧失，一名是由于砧镫关节脱位，另一名是由于卵圆窗膜迷路瘘。据推测，通过咽鼓管迅速传递的过大压力导致了这两种损伤。
