Summary
This case study reports a rare instance of complete congenital facial nerve agenesis in a child. The condition was discovered during surgery for a non-tuberculous mycobacterial infection of the parotid gland.
Area of Science:
- Pediatric Neurology
- Otolaryngology
- Infectious Diseases
Background:
- Congenital facial palsy presents diagnostic challenges.
- Non-tuberculous mycobacterial (NTM) infections can affect salivary glands.
- Facial nerve exploration is typically not indicated for congenital palsy.
Observation:
- A seven-year-old child with congenital facial palsy developed an NTM infection in the parotid gland.
- Surgery was performed to treat the infection and assess facial nerve status.
- Complete absence of the facial nerve was noted from the stylomastoid foramen into the parotid gland.
Findings:
- This is the first reported case of complete congenital facial nerve agenesis.
- The agenesis was incidentally discovered during treatment for a parotid gland NTM infection.
- Congenital facial nerve agenesis can be present without prior indication for exploration.
Implications:
- Highlights the importance of thorough intraoperative assessment in pediatric cases.
- Suggests potential for incidental diagnosis of rare congenital anomalies.
- Informs surgical planning and counseling for congenital facial paralysis and parotid pathologies.
- Contributes to understanding the spectrum of congenital facial nerve development anomalies.
