Clinical Scorecard: Rhinolith may hide intranasal ectopic tooth

At a Glance

Key Highlights

• A 45-year-old man had six months of foul-smelling right-sided nasal discharge and intermittent mild epistaxis.
• Endoscopy showed a hard, irregular white mass on the nasal cavity floor, partly surrounded by calcified material.
• CT demonstrated a tooth-like structure with enamel- and dentin-like attenuation and a central low-density pulp cavity, with surrounding calcifications consistent with a rhinolith.
• Endoscopic removal was followed by an uneventful recovery and complete resolution of reported symptoms.
• The report notes that asymptomatic intranasal ectopic teeth may be observed with regular follow-up.

Guideline-Based Recommendations

Diagnosis

• The report used nasal endoscopy to visualize the suspected intranasal ectopic tooth.
• CT defined lesion location, morphology, and relationships to surrounding structures.
• The tooth-like structure’s enamel- and dentin-like attenuation and central pulp cavity helped distinguish it from other calcified intranasal lesions.

Management

• The symptomatic patient underwent endoscopic transnasal removal.
• The report states that asymptomatic ectopic intranasal teeth may be managed conservatively with regular observation and follow-up.

Monitoring & Follow-up

• At follow-up, the reported patient’s nasal cavity appeared healthy and symptoms had resolved.
• The report notes regular observation and follow-up for conservatively managed asymptomatic cases.

Risks

• Intranasal ectopic teeth may be asymptomatic or present with nonspecific sinonasal symptoms, including nasal obstruction, rhinorrhea, facial pain, or epistaxis.
• The report notes that calcified intranasal lesions may mimic other entities.
• Potential contributors discussed in the report include eruption obstruction, inadequate dental-arch space, trauma, developmental anomalies, cysts, and genetic predisposition; no definitive cause was identified in this patient.

Patient & Prescribing Data

The case concerned a 45-year-old man with persistent unilateral nasal discharge and intermittent epistaxis; the report also discusses asymptomatic cases.

Endoscopic transnasal removal of the ectopic tooth and rhinolith was followed by an uneventful postoperative course and symptom resolution. No medication regimen was reported.

Clinical Best Practices

• Consider an ectopic tooth among possible causes of a calcified intranasal lesion.
• Assess lesion morphology and surrounding structures with CT and correlate findings with nasal endoscopy.
• Look for organized tooth anatomy, including enamel, dentin, and a pulp cavity, when distinguishing an ectopic tooth from other calcified lesions.
• For asymptomatic cases, the report describes regular observation and follow-up as a management option.
