Saddle Nose Deformity Reconstruction with a Allograft Bone

Area of Science:

• Plastic Surgery
• Otolaryngology
• Biomaterials in Medicine

Background:

• Saddle nose deformity presents significant cosmetic and functional challenges.
• Allograft materials offer a potential solution for nasal reconstruction.
• Previous methods have limitations regarding donor site morbidity and graft availability.

Purpose of the Study:

• To evaluate the efficacy and safety of freeze-dried allograft bone for dorsal augmentation in patients with saddle nose deformity.
• To assess the long-term cosmetic and functional outcomes of this reconstructive technique.
• To determine patient satisfaction and complication rates associated with allograft use.

Main Methods:

• A cohort of 58 patients with saddle nose deformity underwent dorsal augmentation using freeze-dried allograft bone.
• Preoperative and postoperative assessments included clinical examination, computed tomography, 3D modeling, anthropometric measurements, and the Utrecht Questionnaire (UQ) with a visual analogue scale (VAS).
• Grafts were contoured using 3D models and placed under the periosteum via a closed approach.

Main Results:

• 56 out of 58 patients reported satisfaction with the surgical outcomes.
• No major complications or significant graft resorption were observed.
• Significant increase in dorsal height was noted on 3D scanning, with no dorsal expansion. VAS scores improved from 2.3 preoperatively to 8.9 at 1 year postoperatively.

Conclusions:

• Freeze-dried allograft bone is a safe and effective material for dorsal augmentation in rhinoplasty.
• This technique provides lasting cosmetic and functional improvements for saddle nose deformity.
• The use of allograft avoids donor site complications, making it a valuable reconstructive option.
