1/87. Endoscopically assisted removal of unilateral coronoid process hyperplasia.Coronoid process hyperplasia (CPH) is an uncommon disorder characterized by an enlarged coronoid process impinging against the posterior aspect of the zygomatic arch. Young male adults are usually affected, presenting with limited mouth opening, which is typically painless and progressive in nature. The diagnosis of true CPH is established by the findings of (1) uniform coronoid enlargement on radiographic examination and (2) normal bone structure on histopathological examination (i.e., the specimen should be free of any neoplastic growth, such as the previously reported cases of coronoid osteomas, osteochondromas, or exostoses). The treatment is mainly surgical, by means of a coronoidectomy. An intraoral approach is mostly preferred for this procedure to avoid an external scar. However, to avoid the drawbacks of this approach, such as limited exposure and the risk of hematoma and subsequent fibrosis, an extraoral approach may be indicated. This report describes a case of true unilateral CPH in a 17-year-old boy who presented with progressive limited mouth opening in the absence of any pain. Computed tomography (CT) demonstrated a uniformly enlarged right coronoid process. A coronoidectomy was performed with the aid of endoscopic systems, approaching via two short incisions in the temporal scalp. Histopathological examination of the specimen demonstrated essentially a normal bony structure with no evidence of a neoplasm. The authors present the endoscopically assisted technique of coronoid process excision as an alternative method of surgical treatment of CPH and any mass of the coronoid process in general. With this method, the incision is much shorter than a conventional coronal incision and thus morbidity is diminished considerably.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
2/87. Cystic management in a 10-year old child.cysts are among the most common lesions found in the oral cavity. These may be developmental in origin or secondary to chronic infections. Untreated, cysts may expand causing local tissue destruction and deformities. Basically, two treatment methods are employed. Enucleation and/or Marsupialization. The following case involves a child treated at the College of dentistry, University of the philippines, for a large cystic lesion involving the permanent cuspid and the deciduous dentition. The lesion was accidentally discovered on a panoramic radiograph. The child underwent extraction of deciduous teeth and marsupialization, which later helped in the eruption of the malposed permanent teeth.- - - - - - - - - - ranking = 4.5881462295827keywords = oral cavity, cavity (Clic here for more details about this article) |
3/87. Giant ranula causing mandibular prognathism.This is a case report of a 20-year-old man with ranula, the size of an orange, in the floor of the mouth causing mandibular prognathism with fan-shaped mandibular teeth anterior to the premolars. The tumor was extirpated. The pathogenesis, differential diagnosis and treatment of ranulas are discussed.- - - - - - - - - - ranking = 0.5keywords = mouth (Clic here for more details about this article) |
4/87. Imaging of a Stafne bone cavity: what MR adds and why a new name is needed.Stafne bone cavities are asymptomatic radiolucencies seen at the angle of the mandible. Although plain films are often sufficient for diagnosis, confirmatory imaging is needed in atypical cases. We describe the MR imaging findings of a Stafne bone cavity, describe the contents, explain why a new name is needed, and discuss the relative merits of different radiologic techniques for establishing this diagnosis.- - - - - - - - - - ranking = 4.8987897872912keywords = cavity (Clic here for more details about this article) |
5/87. Pronounced palatal and mandibular tori observed in a patient with chronic phenytoin therapy: a case report.phenytoin, an anticonvulsant drug for epileptic patients, has many adverse effects, including calvarial thickening and coarsening of the facial features. Previous studies have demonstrated that phenytoin has an anabolic action on bone cells. This report describes pronounced palatal and mandibular tori found in a 45-year-old Japanese man undergoing chronic phenytoin therapy. The tori were extremely large, lobular, and symmetrical. A palatal torus appeared along the middle of the hard palate and mandibular tori consisted of 2 pairs of nodular masses extensively filling the lingual floor of the oral cavity. Pronounced osseous outgrowth occurred for the duration of a dose-increase of phenytoin from 1985 to 1997. His parents did not have any palatal or mandibular tori. These facts suggest that these unusual tori may have been the result of chronic phenytoin therapy, rather than association with the familial background.- - - - - - - - - - ranking = 4.5881462295827keywords = oral cavity, cavity (Clic here for more details about this article) |
6/87. Cystic degeneration in fibrous dysplasia of the jaws: a case report.A case of nonspecific cystic degeneration complicating fibrous dysplasia of the mandible is presented. This condition is extremely rare in the jaw bones. The patient had a painless swelling of the right face measuring 10 cm in diameter, and there was no history of trauma. Radiographs showed a poorly defined, "ground glass" radiopaque lesion; a central well-defined cyst was confirmed by means of computed tomography. During surgery, a large cystic cavity with surrounding, soft fibrous bone that merged with the cortex was observed. Histologic examination showed a large non-epithelial-lined cystic cavity with a surrounding fibro-osseous lesion, which was consistent with a diagnosis of fibrous dysplasia.- - - - - - - - - - ranking = 1.9595159149165keywords = cavity (Clic here for more details about this article) |
7/87. Resorption and regeneration of alveolar bone in acute osteomyelitis of the mandible.A 12-year-old boy developed osteomyelitis of the anterior part of the mandible subsequent to a blow on the mouth. The condition resulted in loosening of the lower incisors and considerable loss of alveolar bone. Under conservative treatment the condition subsided and the bone regenerated completely. Radiographs taken at various stages in the treatment show the loss of bone and its gradual regeneration.- - - - - - - - - - ranking = 0.5keywords = mouth (Clic here for more details about this article) |
8/87. Stafne's bone cavity in the anterior mandible: a possible diagnostic challenge.Stafne was the first to report the presence of "bone cavities" in the angle of 35 mandibles. Such cavities generally appear in the area between the mandibular first molar and the mandibular angle, and are not considered rare. One of their primary radiological diagnostic features is the characteristic location below the mandibular canal. Stafne's bone cavity is relatively rare in the anterior mandible. The mandibular canal is not present in the anterior mandible. As a result, diagnosis in the anterior mandible may be missed. Needless treatment modalities such as endodontic treatment, bone trephining, and bone exploration may be conducted. The purpose of the present report is to describe a new case of Stafne's bone cavity in the anterior mandible and discuss the differential diagnosis process. The dental computerized tomography scan is suggested as the most suitable noninvasive diagnostic and follow-up modality for this bony configuration in the anterior mandible.- - - - - - - - - - ranking = 5.8785477447494keywords = cavity (Clic here for more details about this article) |
9/87. trismus due to bilateral mandibular coronoid hyperplasia.Bilateral mandibular coronoid hyperplasia is a rare cause of restricted mouth opening. diagnosis of the condition prior to general anaesthetic is essential, as oral intubation may be impossible. The reported case illustrates the role of computed tomography in assessment of the disorder and effective treatment by coronoidectomy.- - - - - - - - - - ranking = 0.5keywords = mouth (Clic here for more details about this article) |
10/87. Bilateral mandibular cysts associated with cyclosporine use: a case report.Cyclosporin A (CsA) is used in the treatment of patients undergoing renal transplantation. There are a number of side effects associated with its use. In particular, the gingival overgrowth represents the most important in the oral cavity. The authors present a case of bilateral mandibular cysts in an 8-year-old boy, treated with CsA after renal transplantation. The genesis of the mandibular cysts might be associated with the combined use of CsA and a calcium channel blocker post-transplantation. CsA-induced gingival overgrowth might contribute to cysts by two mechanisms: interference with control mechanisms that regulate the reabsorption of gingival stromal tissue, allowing progressive dental eruption, and an increase in the gingival connective tissue components. gingival hypertrophy might mechanically obstruct the eruption of the developing tooth.- - - - - - - - - - ranking = 4.5881462295827keywords = oral cavity, cavity (Clic here for more details about this article) |
