Soft-tissue augmentation and replacement in the head and neck. General considerations

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Surgical Innovation

Background:

• Factors influencing natural biomaterial wound healing also impact synthetic alloplasts.
• Current research focuses on next-generation biomaterials combining synthetic components with bioactive proteins.
• Long-term biocompatibility and avoidance of carcinogenic or immunoreactive properties are critical considerations.

Purpose of the Study:

• To review the factors affecting the success of natural, semisynthetic, and synthetic biomaterials in wound healing and tissue regeneration.
• To explore the potential of new biomaterials, such as resorbable synthetic alloplasts with growth proteins, for tissue regeneration.
• To emphasize the importance of evidence-based selection of biomaterials by surgeons, moving beyond manufacturer recommendations.

Main Methods:

• Review of current literature on biomaterials used in reconstructive surgery.
• Analysis of factors influencing the performance and long-term success of various alloplasts.
• Discussion of emerging biomaterial technologies and their clinical translation.

Main Results:

• New biomaterials integrating synthetic components with bioactive proteins are entering clinical trials.
• These advanced materials may enable tissue regeneration, offering an alternative to permanent implants.
• A trend towards materials with reduced carcinogenic and immunoreactive potential is evident.

Conclusions:

• The future of reconstructive surgery involves biomaterials that promote tissue regeneration and minimize adverse reactions.
• Surgeons must base biomaterial selection on scientific knowledge and clinical evidence, not solely on commercial information.
• Integrating autologous tissues and appropriately selected synthetic materials is key for optimal patient outcomes.
