ABSTRACT The present study aims to evaluate morphologic variations of the upper tarsus in Asians.
Measurements of superior-inferior and medial-lateral lengths were performed on 54 embalmed cadavers. The superior-inferior length of the tarsus was measured at the central and lateral parts. On the basis of the measured values, shapes of the tarsi were evaluated and categorized.
The tarsi were classified into 3 morphologic categories-the sickle, triangular, and trapezoid types. The upper margins of the sickle, triangular, and trapezoid type tarsi present round, triangular, and flat lines, respectively. Among the 54 examined specimens, 29 (55.6%), 16 (29.6%), and 9 (16.7%) belonged to the sickle, triangular, and trapezoid groups, respectively.
The upper eyelid tarsi present morphologic variations with the Asian population. In performing surgical correction of blepharoptosis or surgical production of double-folds, this individual variation should be taken into consideration.

    ABSTRACT: Asians make up the world's largest ethnic group, and the eyelid is one of the most prominent features of the face, regardless of race. Recent advances in Asian eyelid research have improved the understanding of its unique anatomy and, more importantly, highlighted differences surgeons should be aware of when performing Asian eyelid surgery.

    ABSTRACT: Upper lid blepharoplasty is the most common plastic surgery procedure in Asia and has consistently maintained its position as cultural acceptance and techniques have evolved. Asian upper lid blepharoplasty is a complex procedure that requires comprehensive understanding of the anatomy and precise surgical technique. The creation of the supratarsal crease has gone through many evolutions in technique but the principles and goals remain the same: a functional, natural-appearing eyelid crease that brings out the beauty of the Asian eye. Recent advances have improved functional and aesthetic outcomes of Asian upper lid blepharoplasty.

    ABSTRACT: We reviewed the contributor demographics of recent volumes of Annals of Plastic Surgery to quantify the contributions of authors from countries where the primary language is not English. For 2 volumes of Annals (63 and 65), such authors contributed 57% of the total articles published. Within the new section format of volume 66, authors from non-English language countries accounted for 60% of all original articles with substantial and often dominant representation in all sections. This survey shows that Annals publishes articles from an international population of contributors with effective inclusion of authors from countries with primary languages other than English.
