Hard and soft palate reconstruction

Area of Science:

• Head and Neck Surgery
• Reconstructive Surgery
• Oral and Maxillofacial Surgery

Background:

• Palate reconstruction presents significant challenges for head and neck surgeons.
• Large palate defects, including those from total maxillectomy, require specialized reconstructive approaches.
• A lack of standardized classification hinders comparative studies of palate reconstruction techniques.

Purpose of the Study:

• To review current strategies for palate reconstruction, focusing on large defects.
• To evaluate the efficacy of various microvascular free flaps in restoring palate structure and function.
• To highlight the ongoing challenges in reconstructing dynamic soft palate function.

Main Methods:

• Review of literature on palate reconstruction techniques for large defects.
• Analysis of outcomes associated with microvascular free flaps such as fibular, scapular, and iliac crest/internal oblique.
• Assessment of current limitations in achieving functional soft palate reconstruction.

Main Results:

• Microvascular free flaps containing bone are essential for reconstructing large palate defects, including total maxillectomy defects.
• Fibular, scapular, and iliac crest/internal oblique free flaps have demonstrated promising outcomes for major palate defects.
• Reconstruction of dynamic soft palate function and prevention of velopharyngeal insufficiency remain significant challenges.

Conclusions:

• While bone-containing microvascular free flaps effectively restore structure in large palate defects, functional restoration, particularly of the soft palate, requires further advancement.
• Continued research into techniques for soft palate reconstruction is necessary to address velopharyngeal insufficiency and improve patient outcomes.
