Insights
Pediatric facial palsy (FP) management involves addressing congenital or acquired causes. Early corticosteroid therapy, ocular protection, and dynamic rehabilitation techniques like lengthening temporalis myoplasty (LTM) are recommended for improved outcomes.
Area of Science:
- Pediatric Neurology
- Craniofacial Surgery
- Rehabilitation Medicine
Background:
- Facial palsy (FP) in children presents as congenital or acquired, with congenital cases often linked to trauma and acquired cases requiring etiological investigation.
- Idiopathic facial palsy, where no specific cause is identified, is common and necessitates prompt treatment strategies.
- Understanding the etiology of pediatric facial palsy is crucial for determining prognosis and guiding treatment decisions.
Purpose of the Study:
- To review the etiologies and management strategies for pediatric facial palsy.
- To highlight the importance of dynamic facial rehabilitation, particularly for the lower third of the face.
- To discuss surgical and non-surgical treatment options, including lengthening temporalis myoplasty (LTM) and botulinum toxin injections.
Main Methods:
- Review of current literature on pediatric facial palsy.
- Discussion of treatment protocols including corticosteroids, ocular protection, and surgical interventions.
- Emphasis on dynamic rehabilitation principles and techniques.
Main Results:
- Early oral corticosteroid therapy and ocular protection are standard treatments for idiopathic FP.
- Lengthening temporalis myoplasty (LTM) is recommended for its reliable and harmonious smile outcomes.
- Post-surgical rehabilitation focuses on voluntary movement control and leveraging brain plasticity for spontaneous smiles.
Conclusions:
- Effective management of pediatric facial palsy requires a comprehensive approach, addressing both acute treatment and long-term functional and aesthetic rehabilitation.
- Dynamic rehabilitation, especially targeting the lower facial third, is essential for optimizing outcomes.
- Surgical techniques like LTM and adjunct therapies such as botulinum toxin offer valuable options for improving facial symmetry and function in children.
Abstract:
Facial palsy (FP) in children is congenital or acquired. When present at birth (congenital), etiologies are mostly traumatic and rarely developmental. Acquired FP needs investigation. Research on the etiology helps to determine prognostic and treatment. At most times, no specific cause is found. Treatment of idiopathic FP consists of early oral corticosteroid therapy and ocular protection. Treating the sequelae is essential and the physician has to consider the dynamic balance of both sides of the face. Dynamic rehabilitation should mainly concern the inferior facial third. We recommend the lengthening temporalis myoplasty (LTM). This relevant technique ensures replicable and reliable results with a harmonious smile. Facial dynamic rehabilitation after surgical procedure (muscle tranfer or free muscle flap) must be directed toward control of voluntary movement, to move from a mandibular smile to a spontaneous and voluntary smile, thanks to brain plasticity. Furthermore, botulinum toxin is well tolerated and remains a great tool to treat a child who can support injections.
