1/6. Computerized tomography in the management and follow-up of extensive periapical lesion.Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
2/6. Primary intraosseous verrucous carcinoma developing from a maxillary odontogenic cyst: case report.Primary intraosseous carcinoma (PIOC) is an extremely rare lesion, almost always occurring in cranial bones. The origin of this tumor, specific to the maxillae, is associated with the cells of the epithelial rests of Malassez. Among the histotypes which can be included in these neoplasms, verrucous carcinoma is of particular interest due to its rarity: only a single case has been reported to date. After a short survey of the literature, the authors describe a directly observed case of verrucous carcinoma arising from a maxillary odontogenic cyst.- - - - - - - - - - ranking = 9.7791773864813keywords = neoplasm (Clic here for more details about this article) |
3/6. Maxillary unicystic ameloblastoma.The authors present the case of a 17-year-old White male patient complaining of enlargement in the gingival region and the fundus of the left maxillary anterior vestibular sulcus. The clinicopathological diagnosis was plexiform unicystic ameloblastoma. With this report, the authors illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the maxilla, among them inflammatory radicular cysts, odontogenic keratocysts, adenomatoid odontogenic and unicystic ameloblastoma.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
4/6. fibula flap reconstruction of the condyle in disarticulation resections of the mandible: a case report and review of the technique.Segmental resection of the mandible with disarticulation of the temporomandibular joint is occasionally required in the management of extensive tumors. The reconstruction of these deformities is complex, frequently involves staged procedures, and may result in significant deformity and loss of function for patients. The fibula free flap has become a standard treatment option for primary restoration of segmental mandibular deformities. However, little is published about its role in reconstructing the mandibular condyle. This paper describes a simplified technique for primary reconstruction of mandibular defects, including the mandibular condyle, in disarticulation resections of the mandible utilizing the fibula free flap.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
5/6. lymph node metastasis in spindle cell carcinoma arising in odontogenic cyst. Report of a case.The majority of primary intraosseous carcinomas of the jaws develop in preexisting odontogenic cysts. These tumors are usually well-differentiated keratinizing carcinomas with relatively good prognosis. Only two of 41 previously reported acceptable cases of primary intraosseous carcinomas from ex-odontogenic cysts were associated with cervical lymph node metastasis. Spindle cell carcinoma is an anaplastic dimorphic neoplasm with poor prognosis. It has a special predilection for the upper aerodigestive tract. This is to our knowledge the first report of spindle cell carcinoma developing in an odontogenic cyst. Cervical lymph node metastasis showing typical histologic features of spindle cell carcinoma was detected 8 months postoperatively. The prognostic implications of this finding are discussed in light of previously reported cases of intraosseous carcinoma arising in odontogenic cysts and of spindle cell carcinoma of the oral cavity.- - - - - - - - - - ranking = 9.7791773864813keywords = neoplasm (Clic here for more details about this article) |
6/6. Maxillofacial considerations for diagnosis and treatment in Gorlin's syndrome: access osteotomies for cyst removal and orthognathic surgery.Gorlin's syndrome is a complex hamartomatous/neoplastic syndrome with multisystemic manifestations involving the skin, central nervous system, and bony skeleton. The purpose of this article is to describe how a patient with Gorlin's syndrome was managed with a multipronged approach that included exposure osteotomies for keratocyst removal combined with orthognathic surgery. This case demonstrates the advantages of standard maxillofacial osteotomies to gain access for the removal of odontogenic cysts and benign tumors.- - - - - - - - - - ranking = 1keywords = complex (Clic here for more details about this article) |
