Hypertrophic scarring in cleft lip repair: a comparison of incidence among ethnic groups.

Background: Although hypertrophic scar (HTS) formation following cleft lip repair is relatively common, published rates vary widely, from 1% to nearly 50%. The risk factors associated with HTS formation in cleft patients are not well characterized. The primary aim of this retrospective study of 180 cleft lip repairs is to evaluate the frequency of postoperative HTS among various ethnic groups following cleft lip repair.

Is presurgical nasoalveolar molding therapy more effective in unilateral or bilateral cleft lip-cleft palate patients?
