Area of Science:

  • Plastic Surgery
  • Facial Reconstruction
  • Rhinoplasty Techniques

Background:

  • Dorsal augmentation in rhinoplasty presents significant challenges.
  • Previous methods like solid grafts and diced cartilage fascia (DC-F) have limitations such as warping and irregularities.
  • Achieving consistent and predictable dorsal height remains a key difficulty.

Purpose of the Study:

  • To evaluate a novel composite dorsal augmentation technique in rhinoplasty.
  • To assess the efficacy of combining foundational spreader grafts and dorsal gap grafts with a fascial contour layer.
  • To determine if this multi-graft approach can reliably achieve desired nasal height and aesthetic goals.

Main Methods:

  • A retrospective review of 51 patients undergoing composite dorsal augmentation between 2017 and 2020.
  • Application of a step-by-step algorithm to determine and achieve target dorsal height.
  • Categorization of patients into three groups based on the type of contour graft used (double-layer fascia, segmental DC-F, or narrow thin full-length DC-F).

Main Results:

  • Successful smooth continuity and increased projection of the nasal dorsum were achieved in all patients.
  • The composite technique demonstrated efficacy in achieving dorsal augmentations of 4 mm or more.
  • All patient groups showed positive aesthetic results with improved dorsal form.

Conclusions:

  • The described composite dorsal augmentation technique is effective for significant nasal height increase (≥4 mm).
  • This multi-graft approach allows for camouflage of dorsal irregularities and enhancement of aesthetic lines.
  • The technique offers a versatile algorithm for optimizing the patient's nasal aesthetic profile using grafts from a single donor site.
