Mimetic surgery for the paralyzed face. Neural and plastic procedures

Area of Science:

• Neurosurgery
• Plastic Surgery
• Oncology

Background:

• Facial nerve paralysis presents significant functional and cosmetic challenges.
• Surgical interventions are crucial for restoring facial function after paralysis, often caused by tumors or trauma.
• Various surgical techniques exist, including neural reconstruction, muscle-fascia transposition, and plastic reconstruction.

Purpose of the Study:

• To compare the efficacy of different surgical methods for treating facial nerve paralysis.
• To evaluate the outcomes of neural repairs versus other reconstructive techniques.
• To establish a hierarchy of surgical procedures based on functional and cosmetic results.

Main Methods:

• Retrospective analysis of 138 patients with total or segmental facial nerve paralysis.
• Categorization of patients based on etiology (oncologic, idiopathic) and paralysis type.
• Surgical treatments included neural reconstructions, neuromuscular pedicles, muscle-fascia transpositions, neural transpositions, and plastic reconstructions.
• Outcomes assessed using various grading systems with an average follow-up of 3.4 years.

Main Results:

• Neural repairs demonstrated superior functional and cosmetic results compared to muscle-fascia transpositions and plastic reconstructions.
• In total paralysis cases, 75 patients underwent neural reconstructions with positive outcomes.
• The average follow-up for the neural repair group was 3.6 years, indicating sustained benefits.

Conclusions:

• Neural repair techniques are the preferred surgical approach for achieving optimal outcomes in facial nerve paralysis.
• The study provides a hierarchical ranking of surgical procedures, guiding clinical decision-making.
• Further research may focus on refining neural repair techniques for even better functional and aesthetic restoration.
