1/138. 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 = process (Clic here for more details about this article) |
2/138. Massive osteolysis of the mandible: report of a case with multifocal bone loss.osteolysis of the jaws has been reported in association with infection, cysts, neoplasia, and metabolic, endocrine, or hematologic abnormalities. Rare cases of idiopathic osteolysis have also been recorded. We report the case of a 10-year-old girl with mandibular basal and alveolar bone resorption that has continued over a period of 9 years. The patient has subsequently developed bilateral resorption of the ascending rami and condyles. The maxilla is uninvolved. Investigations included radiology, computerized tomography, scintigraphy, hematology, serum chemistry, endocrinology, histopathology, microbiology, and immunology. Neutrophil chemotaxis, chemiluminescence, and random migration values were low but within the normal range. These findings are interpreted as indicating an unusual variant of massive osteolysis.- - - - - - - - - - ranking = 6.0262472785316keywords = alveolar (Clic here for more details about this article) |
3/138. Progressive unilateral mandibular swelling in adolescence: a diagnostic dilemma.Asymmetrical swelling of the mandible in adolescence may pose a significant diagnostic dilemma. The differential diagnosis ranges from traumatic, infectious, and metabolic processes to benign and malignant tumors. Among them, fibrous dysplasia, osteomyelitis, and malignancy may present with similar clinical and radiological features, making an accurate diagnosis quite difficult. This is an illustrative case involving a 14-year-old girl who initially presented with diffuse fibrous dysplasia of the mandible and in whom a superimposed osteomyelitis of the left side subsequently developed. Multiple investigations and several biopsies were required to arrive at a diagnosis. Similarities in clinical and radiographic findings of fibrous dysplasia, osteomyelitis, and malignancy are presented, and implications for treatment are discussed.- - - - - - - - - - ranking = 0.11111111111111keywords = process (Clic here for more details about this article) |
4/138. Malignant spindle cell tumor arising in the mandible of a patient with florid osseous dysplasia.Florid osseous dysplasia is a non-neoplastic condition of the alveolar processes of the jaws characterized by the replacement of multiple foci of bone by fibrous connective tissue, accompanied by gradual deposition of cementum, bone, or both. The lesions are not associated with inflammatory diseases of the dental pulp or periodontal tissues. In fully developed florid osseous dysplasia, there are multiple lobulated masses in the alveolar bone bilaterally in the mandible and sometimes in the maxilla. This is the first report of a malignancy originating within the jaws of a patient with florid osseous dysplasia. A spindle cell malignancy was diagnosed in the mandible of a 54-year-old black woman whose jaw was affected by florid osseous dysplasia bilaterally. Despite extensive surgery and radiotherapy, the patient died 20 months after diagnosis of the malignancy.- - - - - - - - - - ranking = 12.163605668174keywords = alveolar, process (Clic here for more details about this article) |
5/138. Aneurysmal bone cyst of the coronoid process of the mandible.A rare case of an aneurysmal bone cyst (ABC) involving the right coronoid process of the mandible in a 12-year-old girl is presented. The characteristic features with fluid-fluid levels within the lesion observed on magnetic resonance imaging (MRI) and Computed tomography (CT) was helpful in the preoperative diagnosis.- - - - - - - - - - ranking = 0.55555555555556keywords = process (Clic here for more details about this article) |
6/138. Bilateral enlargement of the mandibular coronoid processes in a patient with rheumatoid arthritis of the temporomandibular joints.A case of rheumatoid arthritis of the temporomandibular joint with enlargement of both coronoid processes has been presented. Limited excursions of the mandible were due mainly to the encroachment of the coronoid processes on the posterolateral surfaces of the maxilla. The condition was relieved by unilateral arthroplasty and bilateral coronoidectomies. The etiology of the enlarged coronoid processes is unknown. However, the condition does resemble that which occurs experimentally when condylectomy is performed and the ramus is shortened. In this case, shortening of the ramus could be attributed to condylar destruction by the arthritic condition.- - - - - - - - - - ranking = 0.77777777777778keywords = process (Clic here for more details about this article) |
7/138. Idiopathic condylar resorption: diagnosis, treatment protocol, and outcomes.Idiopathic condylar resorption is a poorly understood progressive disease that affects the TMJ and that can result in malocclusion, facial disfigurement, TMJ dysfunction, and pain. This article presents the diagnostic criteria for idiopathic condylar resorption and a new treatment protocol for management of this pathologic condition. Idiopathic condylar resorption most often occurs in teenage girls but can occur at any age, although rarely over the age of 40 years. These patients have a common facial morphology including: (1) high occlusal and mandibular plane angles, (2) progressively retruding mandible, and (3) Class II occlusion with or without open bite. Imaging usually demonstrates small resorbing condyles and TMJ articular disk dislocations. A specific treatment protocol has been developed to treat this condition that includes: (1) removal of hyperplastic synovial and bilaminar tissue; (2) disk repositioning and ligament repair; and (3) indicated orthognathic surgery to correct the functional and esthetic facial deformity. patients with this condition respond well to the treatment protocol presented herein with elimination of the disease process. Two cases are presented to demonstrate this treatment protocol and outcomes that can be achieved. Idiopathic condylar resorption is a progressive disease that can be eliminated with the appropriate treatment protocol.- - - - - - - - - - ranking = 0.11111111111111keywords = process (Clic here for more details about this article) |
8/138. 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 = 30.131236392658keywords = alveolar (Clic here for more details about this article) |
9/138. Foreign body granuloma following placement of hard tissue replacement material: a case report.The placement of grafting material in extraction sites for ridge preservation is an increasingly common practice among clinicians. This is a case report of a patient presenting with a symptomatic, foreign body granuloma following the placement of hard tissue replacement (HTR) in extraction sockets. The surgical specimen revealed numerous histiocytes and foreign body type giant cells. The grafting material was surgically removed and the patient's symptoms were alleviated. Although biocompatibility of HTR has previously been shown, specific applications may be contraindicated or some patients may exhibit sensitivity to this material.- - - - - - - - - - ranking = 3.5756995870391keywords = ridge (Clic here for more details about this article) |
10/138. Case report of regional alveolar bone actinomycosis: a juvenile periodontitis-like lesion.BACKGROUND: Cervicofacial actinomycosis infection most often involves the mandibular bone and rarely the alveolar crest. methods: We describe a 14-year-old patient who had actinomycosis involving the alveolar bone at the left lower dental quadrant region. Resembling juvenile periodontitis, it was difficult to diagnose properly and resulted in devastating dental and periodontal consequences: loss of one tooth with most of its adjacent regional alveolar bone, severely compromising the support of two other teeth. RESULTS: With the diagnosis came successful treatment, including surgical removal of the soft and hard tissues with concomitant prolonged penicillin administration. CONCLUSIONS: We feel that this case should raise the interest and concern of both the periodontist and the general practitioner so that early diagnosis can be obtained, significantly improving the clinical outcome.- - - - - - - - - - ranking = 42.183730949721keywords = alveolar (Clic here for more details about this article) |
