Summary
Bilateral accessory maxillary jaws, a rare condition, were identified in a 7-year-old girl. Histologic analysis confirmed teeth within bony growths, suggesting an isolated developmental anomaly.
Area of Science:
- Oral and Maxillofacial Surgery
- Developmental Biology
- Pediatric Dentistry
Background:
- Accessory maxillary jaws represent an exceedingly rare congenital anomaly.
- Bilateral presentations are exceptionally uncommon, with only one prior case documented in English literature.
Observation:
- A 7-year-old female presented with bilateral bony exostoses originating from the maxillary tuberosities.
- The patient exhibited limited mandibular mobility, specifically in protrusive and lateral excursive movements.
Findings:
- Histological examination of the bony exostoses revealed the presence of developing teeth in various stages.
- The findings support the classification of these structures as an isolated form of bilateral accessory maxillary jaws.
Implications:
- This case expands the understanding of rare craniofacial developmental anomalies.
- It highlights the importance of thorough clinical and histological evaluation for diagnosing unusual jaw formations in pediatric patients.
- Further research may elucidate the specific developmental pathways involved in accessory jaw formation.
