Dentigerous cyst of the maxillary sinus in a child

Area of Science:

• Odontogenic Cysts
• Pediatric Maxillofacial Pathology
• Otorhinolaryngology

Background:

• Dentigerous cysts are developmental odontogenic cysts, typically associated with unerupted teeth.
• Maxillary sinus involvement by dentigerous cysts is rare, particularly in pediatric populations.
• Previous studies indicate dentigerous cysts represent a small percentage of diagnosed oral tumors.

Observation:

• A pediatric case presenting with significant facial swelling due to a dentigerous cyst within the maxillary sinus.
• The cyst's location and size led to pronounced clinical manifestations.
• Diagnostic imaging confirmed the cyst's origin and extent.

Findings:

• Successful management of the dentigerous cyst was achieved through endoscopic marsupialization.
• This minimally invasive technique allowed for cyst decompression and sinus drainage.
• Histopathological examination confirmed the diagnosis of a dentigerous cyst.

Implications:

• Highlights the importance of considering rare pathologies like dentigerous cysts in pediatric maxillofacial swelling.
• Demonstrates the efficacy of endoscopic marsupialization as a treatment option for maxillary sinus cysts.
• Contributes to the limited literature on pediatric dentigerous cysts in the maxillary sinus, particularly in Asian populations.
