Head and Neck Wound Reconstruction Using Biodegradable Temporizing Matrix Versus Collagen-Chondroitin Silicone...

Area of Science:

• Regenerative Medicine
• Biomaterials Science
• Plastic and Reconstructive Surgery

Background:

• Head and neck reconstruction presents significant challenges due to functional and aesthetic demands.
• This study is the first to compare Novosorb biodegradable temporizing matrix (BTM) and Integra collagen-chondroitin silicone (CCS) for soft tissue reconstruction in this region.

Purpose of the Study:

• To compare the efficacy and safety of BTM and CCS skin substitutes in head and neck soft tissue reconstruction.
• To evaluate complication rates, closure rates, and the need for secondary procedures between the two biomaterials.

Main Methods:

• A retrospective review of adult patients undergoing head and neck wound reconstruction with either BTM or CCS between 2015 and 2020.
• Comparison of patient demographics, wound etiologies, complication data, and closure rates between the BTM and CCS groups.

Main Results:

• Wound etiologies differed significantly between groups (p=.026), with burns more common in the CCS group.
• While infection, hematoma, and seroma rates were comparable, BTM showed a trend towards lower skin graft failure (0% vs 37.5%) and required fewer secondary procedures (0.9 vs 1.9).
• Definitive closure was achieved in 100% of BTM cases versus 75% of CCS cases.

Conclusions:

• Novosorb BTM demonstrates comparable closure and complication rates to CCS for head and neck reconstruction.
• BTM may be a cost-effective alternative, potentially reducing the need for secondary procedures and skin grafts.
• BTM is a safe and efficacious option for head and neck wound reconstruction.
