Summary
A rare recurrent calcifying odontogenic cyst involving the maxillary sinus presented in a patient 8 years post-enucleation. This case highlights the potential for recurrence and significant maxillary sinus invasion, challenging previous assumptions.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Otolaryngology
Background:
- Calcifying odontogenic cyst (COC) is an uncommon jaw lesion.
- Maxillary sinus involvement by COC is rare.
- Enucleation with curettage is the standard treatment, with low recurrence rates expected.
Observation:
- A large, recurrent COC extensively involved the maxillary sinus.
- The lesion eroded the orbital floor and maxillary sinus walls.
- An impacted canine was displaced into the nasal cavity.
Findings:
- This is the first reported case of recurrent COC involving the maxillary sinus.
- The recurrence occurred 8 years after initial enucleation.
- Extensive local invasion and displacement of dental structures were noted.
Implications:
- Recurrence of COC, even after seemingly complete removal, is possible.
- Maxillary sinus involvement by recurrent COC can lead to significant complications.
- This case underscores the need for vigilant follow-up after COC treatment.
