Expansile dentigerous cyst invading the entire maxillary sinus: a case report

Abstract

(J Korean Assoc Oral Maxillofac Surg 2012;38:245-8) Reported cases of a large dentigerous cyst involving the whole maxillary sinus are uncommon. A 22-year-old female patient suffering from swelling of the right infraorbital area and cheek with dull pain was referred to our department. Findings on computed tomography (CT) and magnetic resonance imaging (MRI) revealed a huge mass containing a displaced maxillary third molar involving the right maxillary sinus as a whole, with partial erosion of the posterior sinus cortical bone. Under general anesthesia, the mass was enucleated using the Caldwell-Luc approach, and, following histopathological analysis, was diagnosed as a dentigerous cyst. The case was followed for a period of seven years, and no evidence of sinus infection or recurring cyst formation was observed during that time.Key words: Dentigerous cyst, Maxillary sinus, Ectopic third molar [paper submitted 2012. 2. 9 / revised 2012. 2. 10 / accepted 2012. 5. 3] large and have the potential to develop into an odontogenic tumor such as ameloblastoma or to become malignant as in oral squamous cell carcinoma and mucoepidermoid carcinoma. The standard treatment for a dentigerous cyst involves surgical enucleation and extraction of the cyst-associated impacted or unerupted tooth 3,4 , but long time for followup is required to rule out postoperative recurrence and postoperative cystic development 5 . The present case of an extensive dentigerous cyst involving the whole maxillary sinus in a 22-year-old female is not common; the lesion was enucleated by the Caldwell-Luc approach supported by computed tomography (CT) and magnetic resonance imaging (MRI) scan. The case was followed for a period of 7 years, and there was no evidence of sinus infection or recurring cyst formation. Thus, we present the case with literature reviews. II. Case reportA 22-year-old female patient under orthodontic treatment at a local clinic was referred to our department for further evaluation. The patient suffered from swelling and dull pain around the right infraorbital area, with partial right-sided nasal obstruction and watering of the right eye. The intraoral

Management of rare ectopic teeth eruption: case series

“…Ectopic teeth have been reported in various locations, including the antrum, floor of the orbit, lower border of the mandible, nasal cavity, ramus, coronoid, condyle and sigmoid notch 3 - 6 , 9 , 10 . The ectopic tooth is a rare entity; only a few have been reported 10 .…”

“…The mean age at presentation was 16.4 years. Maxillary dentigerous cysts are usually common in adolescents and those in their twenties and thirties 6 , 7 , 12 ; however, one reported case was in a patient as young as four years old 14 . Zhang et al’s study of 2,029 dentigerous cysts of the jaws 13 demonstrated that dentigerous cysts are rare in the first decade of life and are most common in the second and third decades.…”

“…Ectopic tooth impaction is a relatively uncommon phenomenon 1 in which the eruption is out of the dental apparatus or no part of the tooth is within the eruption zone 2 . Supernumerary, deciduous, and permanent teeth have been reported in diverse heterotopic positions, including the nasal cavity, maxillary sinus, orbit, palate, mandibular condyle and coronoid process 3 - 6 .…”

Expansile keratocystic odontogenic tumor in the maxilla: immunohistochemical studies and review of literature

“…For the complete excision of the expansile tumor and achievement of hemostasis in the maxilla particularly in anatomical fragile portions such as posterior maxillary wall and lateral nasal space and orbital floor, more extensive approaches are needed even though a lesion has no malignant evidences. Anatomically less dense structure, such as maxillary sinus, could allow the rapid growth of the lesion and tolerate the tumor's occupancy in the entire maxilla within a short period of time 16 , 18 , 19 . In this study, two cases of KCOT were developed and expanded in the unilateral entire maxilla and maxillary sinus, invading the opposite site of the maxilla.…”
