Background: Repair of unilateral incomplete cleft lip is the surgeon's opportunity to achieve a superior result with few revisions.

Methods: This study is a retrospective review of consecutive patients with unilateral incomplete cleft lip, defined as a defect extending 30 to 90 percent of cutaneous labial height, treated between 1985 and 2013 by one surgeon. Rates and types of revisions were collected, and photographs of patients who did not have a revision were reviewed to determine whether a revision was needed.

Objective: To examine the impact of dentofacial infant orthopedic treatment (DFIO) on facial growth in preadolescent children with unilateral complete cleft lip and palate (UCCLP) and bilateral complete cleft lip and palate (BCCLP).

Methods: This is a retrospective study of patients with UCCLP and BCCLP treated at a single center. The treatment group had DFIO, and the control group did not have DFIO.

Frontoorbital advancement (FOA) improves forehead and superior orbital asymmetry associated with unilateral coronal synostosis but has little effect on facial asymmetry. This study compares frontofacial symmetry after FOA and endoscopically assisted suturectomy (ESC) and postoperative helmet therapy.A retrospective review of 2 cohorts of patients with nonsyndromic unilateral coronal synostosis who had either FOA or ESC was undertaken.

Human tooth agenesis involves the absence of one or more teeth and often refers to a genetic or a developmental disorder. Identifying whether certain patterns of tooth agenesis are more prevalent than others may prove valuable for treatment planning, as well as for genetic research into its etiology and development. In the present article a method is described where unique values are assigned to patterns of tooth agenesis.
