Antihelical Auricular Reconstruction With Adipoperichondrial Turnover Flap and Full-thickness Skin Graft

Abstract

trismus is due to the chronic bilateral muscular strain, probably from the sternocleidomastoid muscles.A previous case-control study 6 demonstrates that congenital muscular torticollis results in ipsilateral mastoid process hypertrophy with approximately 10 cm 3 difference between both the case control group and within the study group when comparing one side to the other. Chronic strain from the sternocleidomastoid muscle exerts tension on the mastoid process resulting in bone hypertrophy as it adapts to stress. The stretching of the bone activates osteoblast in the direction of tension. 7 To our knowledge this is the first report on bilateral mastoid process hypertrophy associated with severe trismus.
