Giant Complex Odontoma Occurring Independently Within the Maxillary Sinus.

Area of Science:

• Oral and Maxillofacial Surgery
• Otorhinolaryngology
• Pathology of Odontogenic Tumors

Background:

• Complex odontomas are rare benign odontogenic tumors.
• Previous cases in the maxillary sinus were associated with the alveolar process.
• Giant complex odontomas entirely within the sinus are exceptionally rare.

Purpose of the Study:

• To report a unique case of a giant complex odontoma.
• To describe its presentation entirely within the maxillary sinus.
• To document the surgical management and outcome.

Main Methods:

• A rare case of giant complex odontoma was identified.
• Surgical excision was performed via the Caldwell-Luc operation.
• General anesthesia was utilized, and the bony defect was reconstructed with titanium mesh.

Main Results:

• A giant complex odontoma was successfully removed from the maxillary sinus.
• The lesion was completely intra-sinus and unassociated with the alveolar process.
• Post-operative recovery was uneventful with successful defect closure.

Conclusions:

• Giant complex odontomas can arise independently within the maxillary sinus.
• The Caldwell-Luc operation is an effective surgical approach for such lesions.
• Titanium mesh provides a viable option for bony defect reconstruction.
