Intranasal supernumerary tooth in a child: a case report.

Area of Science:

• Otorhinolaryngology
• Pediatric Dentistry
• Medical Imaging

Background:

• Ectopic eruption of supernumerary teeth in the nasal cavity is exceptionally rare, often associated with the maxillary sinus or dental cysts, typically diagnosed in adulthood.
• Nasal supernumerary teeth can present asymptomatically or with vague symptoms, delaying diagnosis, especially in pediatric cases.

Observation:

• A 5-year-old child presented with a year-long history of intermittent nasal bleeding and symptoms suggestive of allergic rhinitis, including nasal obstruction.
• Nasal endoscopy revealed a needle-like, whitish mass on the left nasal floor.
• Paranasal sinus computed tomography (CT) identified a pointed, high-density mass covered by soft tissue within the nasal cavity.

Findings:

• The intranasal mass was definitively identified as a supernumerary tooth.
• Complete surgical removal of the supernumerary tooth was achieved using a pediatric endoscope.

Implications:

• This case highlights the importance of considering supernumerary teeth in the differential diagnosis of pediatric intranasal masses and epistaxis, even with nonspecific symptoms.
• Early detection and endoscopic removal are key for optimal treatment outcomes in children with nasal supernumerary teeth.
• This report aims to increase clinical awareness and provide evidence for the characterization and management of this rare condition in pediatric patients.
