Area of Science:

Biomedical Engineering
Surgical Technology
Regenerative Medicine

Background:

Nasal reconstruction demands a blend of aesthetic and functional restoration.
Three-dimensional (3D) printing offers patient-specific solutions for complex nasal defects.

Purpose of the Study:

To review the applications, benefits, and challenges of 3D printing in nasal reconstruction.
To assess the impact of 3D-printed models, implants, and scaffolds on surgical outcomes.

Main Methods:

Literature search of PubMed, Scopus, and Web of Science for studies on 3D printing in nasal reconstruction.
Analysis of peer-reviewed articles and clinical trials on 3D-printed components and bioprinting techniques.

Main Results:

3D printing enables precise anatomical models, surgical guides, and implants using techniques like SLA and SLS.
Materials include polylactic acid, titanium, and hydroxyapatite; CFD tools aid surgical planning.
3D-printed guides reduce operative time and improve symmetry; bioprinting shows regenerative promise.

Conclusions:

3D printing provides significant advantages in precision and outcomes for select nasal reconstruction cases.
Overcoming challenges in cost, imaging, regulation, and vascularization is key for wider clinical integration.
Future advancements in bioactive materials and AI-assisted design will further enhance reconstructive surgery.
