New Technologies in Rhinoplasty: A Comprehensive Workflow for Computer-assisted Planning and Execution

Area of Science:

• Plastic Surgery
• Medical Technology
• 3D Imaging

Background:

• Rhinoplasty in facial cleft patients presents significant reconstructive challenges due to anatomical variability.
• Traditional surgical planning often focuses on soft tissues, which can be insufficient for complex bony irregularities.

Purpose of the Study:

• To present a comprehensive workflow for "bottom-up" computer-assisted planning and execution in complex rhinoplasty.
• To integrate novel advanced technologies for improved preoperative assessment and surgical guidance.

Main Methods:

• Utilizing 3-dimensional imaging for detailed preoperative analysis.
• Implementing a "bottom-up" planning strategy, focusing on substructure reconstruction first.
• Employing computer-assisted planning, grafting templates, 3D-guided osteotomies, piezotome, and intraoperative navigation.

Main Results:

• The workflow enables meticulous planning and precise execution of complex rhinoplasty.
• Integration of multiple advanced technologies enhances the surgical approach.
• Facilitates a shift from soft-tissue morphing to substructure reconstruction for improved outcomes.

Conclusions:

• The presented workflow offers a simple, effective, and safe method for planning complex rhinoplasty cases.
• Combining preoperative computer analysis, virtual planning, and intraoperative navigation leads to consistent and favorable clinical results.
• This approach addresses the need for enhanced minimally invasive techniques in reconstructive facial surgery.
