Patients with repaired cleft lip may develop lower lip deformities. Analysis of 63 patients revealed typical hypertrophied, displaced lower lips, with variable mandibular changes, often requiring soft-tissue correction for permanent results.

Area of Science:

  • Plastic Surgery
  • Craniofacial Surgery
  • Pediatric Dentistry

Background:

  • Repaired upper lip clefts can lead to secondary lower lip deformities.
  • Understanding these deformities is crucial for effective treatment planning.

Purpose of the Study:

  • To characterize the soft-tissue and skeletal configuration of lower lip deformities in patients with repaired cleft lip.
  • To evaluate the effectiveness of different treatment approaches.

Main Methods:

  • Retrospective analysis of records from 63 patients with repaired cleft lip and lower lip abnormalities.
  • Characterization of soft-tissue and skeletal features of the lower lip and mandible.

Main Results:

  • A typical deformity involved a hypertrophied, superiorly displaced, and anteriorly rotated lower lip.

  • Mandibular skeletal analysis showed variable vertical elongation and posterior chin displacement.
  • Soft-tissue procedures provided permanent correction when the maxillary-mandibular relationship was normal.

    • Conclusions:

    • Lower lip deformities post-cleft lip repair present with distinct soft-tissue and skeletal characteristics.
    • Soft-tissue correction is key for permanent results, contingent on a normal maxilla-mandibular relationship.
    • Skeletal correction alone is insufficient for complete correction of abnormal lower lip posture.
