Ectopic Upper Third Molar in Maxillary Sinus: A Case Report and Literature Review

Area of Science:

• Dentistry
• Oral and Maxillofacial Surgery
• Radiology

Background:

• Ectopic teeth, particularly in the maxillary sinus, are rare occurrences with diverse etiologies including developmental, pathological, and iatrogenic factors.
• Symptoms associated with ectopic teeth vary depending on their location and can range from asymptomatic to significant facial pain and swelling.

Purpose of the Study:

• To report a case of an ectopic third molar within the maxillary sinus.
• To discuss the potential causes and management of this rare condition.

Main Methods:

• A 19-year-old female patient presented with unilateral facial pain and swelling.
• Diagnosis was confirmed using orthopantography and computerized tomography (CT) scans.
• Surgical removal of the ectopic tooth was performed via the Caldwell-Luc procedure.

Main Results:

• The patient presented with a three-month history of left-sided facial pain and swelling.
• Imaging confirmed an ectopic third molar in the left maxillary sinus, likely secondary to prior mid-facial trauma and surgery.
• Post-operative follow-up at three months showed complete resolution of symptoms.

Conclusions:

• Ectopic teeth in the maxillary sinus, though rare, necessitate thorough investigation and appropriate management.
• Surgical intervention, such as the Caldwell-Luc procedure, can be effective in resolving symptoms associated with these conditions.
• This case underscores the importance of considering past trauma or surgical history in the etiology of ectopic maxillary sinus teeth.
