Area of Science:

  • Plastic Surgery
  • Facial Reconstruction
  • Aesthetic Surgery

Background:

  • Progressive premaxillary retrusion is a common consequence of facial aging.
  • Central maxillary insufficiency can occur in specific ethnic groups or due to cleft lip nasal deformity.
  • This condition presents challenges in facial contouring, rhinoplasty, and reconstructive surgery.

Purpose of the Study:

  • To describe techniques for augmenting and reconstructing the premaxillary region.
  • To address deformities related to nasal structure, bone loss, or complex maxillofacial defects.

Main Methods:

  • Utilizing alloplastic implants, autogenous tissue, lipotransfer, or injectable fillers for minor defects.
  • Employing free tissue transfer for larger, composite defects.
  • Surgical techniques focus on addressing osseous resorption and improving facial aesthetics.

Main Results:

  • The described techniques offer solutions for premaxillary retrusion and central maxillary insufficiency.
  • Successful augmentation and reconstruction can correct acute nasolabial angles and ptotic nasal tips.
  • Methods are applicable to diverse patient populations and defect severities.

Conclusions:

  • Effective surgical strategies exist for premaxillary reconstruction.
  • These techniques can restore form and function in cases of midface deficiency.
  • The study provides valuable insights for plastic and reconstructive surgeons managing these complex cases.
