Summary
A rare case of an ectopic third molar obstructing the osteomeatal complex caused nasal blockage. Endoscopic sinus surgery successfully removed the tooth and associated cyst, restoring the patient's breathing.
Area of Science:
- Otorhinolaryngology
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Ectopic third molars are rare dental anomalies.
- Obstruction of the osteomeatal complex can lead to chronic sinusitis and nasal obstruction.
- Computed tomography (CT) is crucial for diagnosing complex sinonasal pathologies.
Observation:
- A 21-year-old male presented with a 2-year history of left-sided nasal obstruction.
- CT revealed an ectopic third molar obstructing the left osteomeatal complex and ethmoid infundibulum.
- Associated left maxillary sinus opacity indicated a dentigerous cyst.
Findings:
- A transnasal endoscopic sinus technique was utilized for surgical intervention.
- The procedure involved creating a middle meatal antrostomy for access.
- Successful removal of the ectopic tooth, cystic contents, and cyst wall was achieved.
Implications:
- Endoscopic sinus surgery offers a minimally invasive approach for ectopic tooth removal.
- This technique resulted in reduced patient morbidity compared to traditional methods like the Caldwell-Luc procedure.
- Restoration of nasal patency and resolution of symptoms were observed post-surgery.
