The current techniques in dorsal augmentation rhinoplasty: a comprehensive review

Abstract

Background: An essential aspect of rhinoplasty is the enhancement of the nasal dorsal contour by performing dorsal augmentation (DA) rhinoplasty. A wide range of techniques are available for DA as the demand for aesthetic nasal refinement grows. This review aims to provide a comprehensive overview of the current techniques used in DA rhinoplasty.

Main body: Research articles on DA rhinoplasty techniques were identified through a comprehensive literature search. Scopus, PubMed, and Web of Science were used as electronic databases. Each database was searched for articles published since its inception. DA rhinoplasty techniques were examined in this literature review. Methodological quality was assessed for the selected studies, and data was extracted to examine materials used, surgical approaches, and reported outcomes for each technique. Various DA methods, including autologous grafts and synthetic implants, are examined in-depth in this review. Comparing approaches can help better understand their respective advantages and limitations.

Conclusion: A wealth of techniques is available for DA rhinoplasty, each with advantages. Patients' nasal anatomy, desired outcomes, and potential risks must be considered by surgeons when determining their surgical approach. DA methods continue to evolve rapidly, creating a need for a thorough understanding of the current landscape to make informed decisions.

The difference between the preoperative and postoperative noses was calculated usinggeometrical shapes. The geometric difference generated a 3D solid model. A nasal implant model was modified to incorporate an octahedralpattern architecture, and a cover mold model was created based on the nasal implant model (a). The pMSTL system is outlined in this schematic (b).the patient-specific OrmoComp cover mold and fabricated PCL nasal implant (c).
