Frontal mucocele caused by an ectopic maxillary tooth.

OBJECTIVE

To present a previously unreported cause of frontal mucocele.

CASE REPORT: A patient presented with a frontal mucocele and maxillary sinusitis. Computed tomography revealed an ectopic maxillary tooth as the cause of her signs and symptoms. Removal of the tooth by a Caldwell-Luc procedure facilitated resolution of the mucocele. Conventional treatment of mucoceles by endoscopic sinus surgery, and other rhinological sequelae of ectopic teeth, are considered.

CONCLUSION

This is the first documented case of an ectopic tooth causing a frontal mucocele, and demonstrates how effectively the patient's symptoms resolved on removal of the tooth.
