Endoscopic Removal of a Dentigerous Cyst Producing Unilateral Maxillary Sinus Opacification on Computed Tomography

Abstract

We report the case ofa 14-year-old girl who was ref erred to us with a 2-yea r history ofabnormal panoramic dental x-rays. Comput ed tomography of the paranasal sinuses demonstrated a left unilateral maxilla ry sinus opacification that had been produced by an ectopic molar: The tooth was removed via an endoscopic app roach rather than with a traditional Caldwell-Lu c procedure. A nasal endoscope was used to create a middle meatal antrostomy and deliver the tooth and its cystic contents. The patient recove red without complications, and she exhibited no signs of recurrence at the 2-year fo llow-up.

Ectopic tooth in maxillary sinus: Case series

“…Many surgical approaches have been reported in the literature including the endoscopic removal of such ectopic teeth and associated lesions. Di Pasquale P and Shermetaro C,[16] used a nasal endoscope to create a middle meatal antrostomy and deliver the ectopic tooth and its cystic contents. The endoscopic techniques are being used for removal of an intranasal ectopic tooth[17] obstructing nasal cavity and ectopic maxillary third molar obstructing osteomeatal complex.…”

Dentigerous cyst associated with an ectopic third molar in the maxillary sinus: A case report and review of literature

“…Endoscopic approach for its management is also described in the literature, which is associated with lesser operative as well as post-operative morbidity. [1]…”

“…These cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. [1] They constitute the second most common cystic lesion of the jaws, after radicular cysts. [2] The literal meaning of dentigerous is ‘tooth bearing.’[3] They are most frequently associated with the crowns of permanent teeth, though few rare cases are reported in association with the crowns of deciduous tooth,[4] complex odontoma,[5] and supernumerary teeth.…”

Clinicopathologic Features of Dentigerous Cysts in the Maxillary Sinus

“…10 Another 4 patients had no clinical symptoms (supplemental digital content Table 1, http://links.lww.com/SCS/A25). 8,9,11,19 Treatment Methods Most DCs in the maxillary sinus, and the impacted or unerupted teeth within, were easily removed via a Caldwell-Luc procedure under direct vision (supplemental digital content Table 2, http://links.lww.com/SCS/A25). If the cyst could not be removed under direct vision, endoscopic sinus surgery 1,3,6,10,11,13,26 was performed.…”

“…11 The risks of the functional endoscopic sinus surgery include recurrent disease and postoperative discharge. Dentigerous cysts in the maxillary sinus that are very close to the osteomeatal complex may be removed endoscopically, but cysts that lie laterally or posteriorly are more easily removed under direct vision that a Caldwell-Luc approach provides.…”
