Highlights
Alar cartilage cephalic malposition was first described as a parenthesis-shaped deformity by Sheen
According to Sheen, this is alar cartilage with a lateral crura oriented towards the medial instead of the lateral canthus of the eyelid[1]
Constantian[2] described this anatomical variation as a “malposition of the alar cartilage”, in which the lateral crus is rotated in the anterior direction and moves away from the nostril plane at an angle of 45o or higher
Summary
Alar cartilage cephalic malposition was first described as a parenthesis-shaped deformity by Sheen. The aim of this study was to analyze the results of treatment by caudal rotation of the lateral crus for this deformity. The “boxy tip” was corrected in 100% of cases; initial alar retraction, 97%; alar pinching, 96%; and external valve collapse, 100%. Conclusions: This study shows that caudal rotation of the lateral crus can treat the deformity described by Sheen with a small number of relapses and without serious complications. Hamra[3] defines such variation as a “malrotated lateral crus” and presents a technique to correct it to the “correct anatomical position”. In a study of 50 consecutive cases by Daniel[6], the author defines “cephalic malposition of the lateral crus” as an offset of 7mm or more from the center of the alar rim. Hamra[3] claims that, considering the high frequency of this anatomical condition, it would be more appropriate to name it “cephalic-positioned” alar cartilage than “malpositioned”
