[Botulinum toxin in oromaxillofacial surgery]

Area of Science:

• Craniomaxillofacial surgery
• Neuromuscular disorders
• Aesthetic medicine

Context:

• The jaw and facial muscular system exhibits complex dynamics, with abnormalities leading to significant aesthetic and functional impairments.
• Current surgical treatments for muscular imbalances are often irreversible and can damage nerve and muscle structures.
• Botulinum toxin A presents a minimally invasive alternative for managing these conditions.

Purpose:

• To survey established and novel applications of botulinum toxin A in craniomaxillofacial surgery.
• To highlight the use of botulinum toxin A for treating masticatory and mimic muscle dysfunctions.
• To explore its role in managing salivary gland disorders and aesthetic corrections.

Summary:

• Botulinum toxin A provides short-term correction of muscular activities with a favorable side effect profile when applied precisely.
• Applications include treating masticatory and mimic muscle imbalances, hypersalivation, Frey's syndrome, and aesthetic facial concerns.
• It serves as an alternative to surgery for temporomandibular joint (TMJ) dislocation and for preventing relapse after mandibular advancement.

Impact:

• Offers a less invasive treatment option compared to traditional surgery for various craniomaxillofacial conditions.
• Improves patient outcomes by addressing both functional deficits and aesthetic concerns associated with muscular disorders.
• Potential to reduce chronic pain and psychopathological conditions linked to persistent facial muscle dysfunction.
