Assessing the Results of Lip Surgery in Patients With Cleft Lip and Palate
Functional Outcomes of Lip Revision

The purpose of this study is to determine whether secondary (revision) surgery to the lip in patients with cleft lip and palate is effective in improving lip function and appearance.

Children born with clefting of the upper lip exhibit obvious disfigurement of the upper lip and nose. As illustrated below, primary lip surgery of the infant dramatically improves the severe deformity of the perioral and nasal region. It is widely recognized, however, that most patients require additional lip surgeries for an optimum esthetic result. Clinicians often disagree as to when this end point is reached since the decision for additional lip revision is based on subjective clinical assessments.

Facial morphology during function has a major impact on how a person is perceived in society and is known to be an important component of the esthetic outcome for cleft patients, but it has been particularly difficult to incorporate measures of lip function into the decision-making process. It is likely that the different surgical procedures for both primary lip closure and secondary lip revision could be improved if the effects of alternative surgical techniques on function were better understood. The subjects for this project consist of two cleft lip and palate patient groups treated at the University of North Carolina (UNC) Craniofacial Center: one cleft group will be patients who are candidates for additional lip revision surgery; the other cleft group will be patients who have been judged not to need lip revision; and a matched non-cleft group who present for routine dental care at UNC School of Dentistry. The goals of this project are to objectively measure and quantify functional facial impairment in cleft patients, and to establish more reliable, functionally relevant outcome criteria for treatment planning and evaluation of these individuals. Our specific aims, therefore, are to

  1. In a prospective non-randomized controlled clinical trial, evaluate the efficacy of lip revision surgery by a) Examining longitudinal changes in function after lip revision, and b) Examining whether the change in function after lip revision differs from the change that would be observed due to maturation only in the matched non-cleft 'normal' group, and the change in the cleft but non-lip revised group.
  2. a) Estimate the effect of cleft lip and palate on function after primary lip and palate repair but prior to lip revision surgery by comparing those patients scheduled to receive a lip revision with those who are judged not to need a lip revision, and b) Estimate the impairment in function in cleft lip and palate patients without lip revision relative to matched non-cleft subjects.
  3. Compare the assessments of dynamic lip function provided by objective measures with subjective clinical judgments/ratings of craniofacial plastic surgeons who perform lip revision surgery, and evaluate the potential of the new methods for clinical application.

To address these aims, we have identified a group of highly qualified individuals with widely recognized expertise in the application of the proposed methodologies, and a panel of surgeons experienced in cleft care for clinical evaluation of outcomes. This expertise, the availability of an appropriate patient resource, and the home institution's 35-year history of strong commitment to the care of these patients and craniofacial research, all favor success in meeting the goals of the project.
