Ectopic Tooth Management in Maxillary Sinus
Summary
Ectopic eruption of a tooth into the maxillary sinus represents an uncommon but clinically significant anomaly. Patients may present with facial pain, nasal discharge, obstructive sinus symptoms or unexpected findings on radiography. Management begins with accurate localisation using advanced imaging modalities, followed by a tailored surgical approach. Traditional access via the Caldwell–Luc antrostomy has gradually given way to less invasive endoscopic techniques, which aim to preserve mucosal integrity and reduce postoperative morbidity. In cases complicated by associated dentigerous cysts, complete enucleation and careful sinus wall repair are paramount to prevent recurrence or secondary infection. Emerging image-guided surgery and three-dimensional reconstruction enhance preoperative planning, while multidisciplinary collaboration between maxillofacial surgeons and otolaryngologists ensures optimal functional and aesthetic outcomes. Conservative monitoring may be appropriate for asymptomatic presentations, but most ectopic teeth in the maxillary antrum benefit from timely removal to alleviate symptoms and avert sinus pathology.

Ectopic Tooth Management in Maxillary Sinus publication trend
The graph below shows the total number of articles in ectopic tooth management in maxillary sinus across all publications each year (not limited to Nature Index journals).
Technical terms
Ectopic tooth: A tooth located outside its normal dental arch, here within the maxillary sinus.
Maxillary sinus: A pyramidal air cavity within the maxilla, forming part of the paranasal sinus system.
Cone beam computed tomography (CBCT): A three-dimensional imaging modality providing detailed views of bony anatomy and dentoalveolar structures.
Cinematic rendering: A post-processing technique that creates life-like, volumetric images from CT data for enhanced anatomical visualisation.
Dentigerous cyst: An odontogenic cyst that forms around the crown of an unerupted tooth and may expand into adjacent spaces.
Caldwell–Luc antrostomy: A surgical approach creating a window in the canine fossa to access and clear the maxillary sinus.
Functional endoscopic sinus surgery (FESS): A minimally invasive technique using endoscopes to restore normal sinus drainage and mucosal function.
