Decompression of Large Keratocystic Odontogenic Tumor: Review of Literature and Case Report

Decompression followed by enucleation of Keratocystic odontogenic tumour (KCOT) is a recommended conserva-tive approach for large KCOT to prevent injury to the surrounding vital structures, pathological fracture of the mandible and radical resection surgery. On the other hand, this approach necessitates multiple surgical procedures and prolonged follow-up which depends on the patient's compliance and may increase the risk of infection.

Large Keratocystic Odontogenic Tumor involving entire maxillary sinus: A common pathology in uncommon location

Keratocystic odontogenic tumor (KOT) is an odontogenic neoplasm of jaw which occurs more frequently in mandible. Its occurrence in maxilla is relatively infrequent. This article reports a case of large KOT of left maxilla involving the entire maxillary sinus extending up to the infra-orbital rim, in a middle aged person. The pathology was treated with surgical enucleation and chemical cauterization. Taking into the consideration the high recurrence rate of KOT, regular and periodic follow up is necessary in such cases. At 2 years follow up the present case showed normal healing with no recurrence. Keywords: Odontogenic keratocyst, Jaw, Tumor, Maxillary Sinus

Conservative Treatment of Keratocystic Odontogenic Tumour:-A Case Report

The treatment of keratocystic odontogenic tumour remains controversial. The aim of this article is to report the outcome of conservative treatment protocol for a large keratocystic odontogenic tumour crossing the midline treated with enucleation and open dressing. A 33 year old male patient with mandibular anterior swelling was referred to Department of Oral and Maxillofacial Surgery. CBCTreports revealed a large radiolucent lesion extending from 37 to 46 region and associated with bilateral mandibular impacted canines. Histopathological evaluation suggested akeratocystic odontogenic tumour. To minimize the possibility of pathologic fracture and complex surgical intervention the patientwas treated by enucleation followed by open packing. This conservative treatmentwas selected since the patient was young.Postoperative results are encouraging. This conservative treatment protocol for keratocystic odontogenic tumors, based on enucleation followed by open packing can be a possible choice in young patients.

Large keratocystic odontogenic tumor of the mandible

The odontogenic keratocyst (OKC) is a rare odontogenic cyst of epithelial origin. There are many types of cysts of the jaws, but what make the odontogenic keratocyst unusual are its characteristic features including its potentially aggressive behavior, high recurrence rate, and an association with the nevoid basal cell carcinoma syndrome. Odontogenic keratocysts, now reclassified as keratocystic odontogenic tumors (KCOTs) by the World Health Organization, are a clinical entity with a characteristic microscopic picture, kinetic growth, and biological behavior. The characteristic features are unique among all the different inflammatory and developmental cysts that occur in the jaws. In this report, we present a 35-year-old female patient with a massive KCOT with buccal cortical plate expansion and unusual anteroposterior extension extending from the premolar area up to the condyle.

Conservative Management of Keratocystic Odontogenic Tumour with Enucleation, Excision of the Overlying Mucosa and Electrocauterization - A Case Report.

Odontogenic keratocyst remains an enigma for clinicians and researchers, although gains in knowledge in recent years have improved the understanding of this interesting lesion. The diagnostic problems are mainly related to the relative lack of specific clinical and radiographic features that unequivocally point to a proper diagnosis. Of particular interest to clinicians is the biologic behaviour of keratocysts which includes high rates of recurrence and potential existence as a benign odontogenic neoplasm, keratocystic odontogenic tumour. Various surgical modalities have evolved in an attempt to reduce the recurrence rate, including curettage, peripheral ostectomy, removal of overlying mucosa in cases of cortical perforation and osseous resection in the form of marginal or segmental osteotomies. The present case report describes the conservative surgical management of a large keratocystic odontogenic tumour in a young patient with no evidence of recurrence at two years follow-up.

A Large Keratocystic Odontogenic Tumor

ABSTRACT Keratocystic odontogenic tumor (KCOT) is described as a benign uni- or multicystic, intraosseous tumor arising from the dental lamina or its remnants. Various treatment modalities available are decompression, marsupialization, enucleation, curettage, resection with and without continuity defect, and disarticulation. Among all of these treatment modalities for large keratocystic odontogenic tumor, marsupialization followed by enucleation is preferred owing to its conservative nature as it decreases the size of the cystic cavity gradually thus, it can save the adjacent anatomic structures. Here, we describe a case of large KCOT which was treated using conservative approach. How to cite this article Jolly S, Lata J. A Large Keratocystic Odontogenic Tumor.

Early reconstruction of bone defect created after initial surgery of a large keratocystic odontogenic tumor: A case report

Keratocystic odontogenic tumor (KCOT) is defined as a benign cystic neoplasm of the jaws of odontogenic origin with a high rate of recurrence. The most lesions occur in the posterior part of the mandible. Treatment of KCOT remains controversial, but the goals of treatment should involve eliminating the potential for recurrence while minimizing surgical morbidity. However, another significant therapeutic problem related to the management of KCOT is an adequate and early reconstruction of the existing jaw defect, as well as appropriate aesthetic and functional rehabilitation of a patient, especially in cases of a very large destruction of the jaws bone. We presented a 65-year-old female patient with very large KCOT of the mandible. Orthopantomographic radiography showed a very large elliptical multilocular radiolucency, located on the right side of the mandible body and the ascending ramus of the mandible, with radiographic evidence of cortical perforation at the anterior border of the mandibular ramus and the superior border of the alveolar part of the mandible. The surgical treatment included two phases. In the first phase, the tumor was removed by enucleation and additional use of Carnoy solution, performing peripheral ostectomy and excision of the affected overlying mucosa, while in the second phase, restorative surgery of the existing mandibular defect was performed 6 months later. Postoperatively, we did not register any of postoperative complications, nor recurrence within 2 years of the follow-up. Adequate and early reconstruction of the existing jaw defect and appropriate aesthetic and functional rehabilitation of the patient should be the primary goal in the treatment of KCOT, having in mind the need for a long-term post-surgical follow-up.

Conservative Management of a Large Keratocystic Odontogenic Tumor in the Maxilla

Keratocystic odontogenic tumor is characterized by high recurrence rates. Conservative or aggressive management has been suggested as a method of treatment. Decompression is a conservative treatment that has been used in the treatment of large odontogenic cysts. The authors report a case of a 14-year-old patient with a keratocystic odontogenic tumor located in the right maxilla, which was treated by decompression followed by enucleation with curettage. The lesion did not recur on follow-up for 3 years after the enucleation surgery.

Secondary Healing After Removal of Large Keratocystic Odontogenic Tumor in the Mandible: Enucleation Followed by Open Packing of Iodoform Gauze

The aim of this retrospective study was to present the findings of an open packing method after enucleation of large keratocystic odontogenic tumors (KCOTs) in the mandible. We performed a retrospective case series study of 27 patients with KCOTs larger than 5 cm treated at our institution between September 2003 and September 2008. A conservative surgical treatment was applied, which involved enucleation of the primary lesion and open packing of the residual osseous defect with iodoform gauze for secondary healing. Bone regeneration, tumor recurrence, and surgical complications were observed and analyzed. We used the χ(2) test and Pearson correlation coefficient for statistical analysis. The postoperative follow-up time was 52.3 months on average (range, 24 to 84 months). The packing gauze was changed every 2 weeks after enucleation, and the total duration for packing was 10.2 months on average (range, 7-15 months). Bone regeneration and satisfactory secondary healing were observed clinically and radiographically after treatment. Only 1 case had a recurrence 6 months after initial treatment, which was attributed to insufficient bony unroofing during enucleation. The recurrent lesion was re-treated by the same method, and no recurrence occurred in the following 6 years. No serious complications from this method of treatment were observed. No significant variables were found to be related to the recurrence. Enucleation with subsequent open packing was shown to be a conservative and comfortable treatment for patients and appears to be an effective choice for the management of large KCOTs in the mandible.

Orthodontic Treatment of Deep Impacted Teeth in Multiple Keratocystic Odontogenic Tumor

Keratocystic odontogenic tumor (KCOT) is an odontogenic tumor derived from odontogenic organs. We present the case of an 11-year-old boy with a large KCOT that contained 6 impacted teeth in the left maxilla and left mandible (upper left canine, upper left first and second premolars, lower left canine, lower left first and second premolars). We selected decompression without extraction of the teeth as a first-step treatment. After decompression, the tumor had reduced in size, and the impacted teeth began to erupt with bone regeneration. We pulled the impacted teeth using orthodontic treatment, enucleated the residual tumor, and finally moved the impacted teeth into an ideal position 4 years after the operation.
