[The maxillofacial functional and esthetic surgical aspects in a case of osteopetrosis].
No full textOsteopetrosis is an extremely rare condition characterized by an increase in osseous cell density. It shows three different hereditary patterns. Diagnosis is made by means of a 3D CT and an accurate study of hepatic and renal functions, as well as audiometric and labyrinth examination. In the frequent case of serious osseous alterations of the facial profile, surgical treatment is essential in order to obtain the best aesthetic and functional results
[Leiomyoma of the masseter muscle. Report of a case].
No full textThe authors present a clinical case of leiomyoma, localized in the anterior margin of the masticator muscle. The clinical diagnosis was formulated following the histological test on the operating part. It is a case a rare pathology of the oral cavity that isn't commonly suspected. The symptoms of the patient let think a pathology of ATM and it was not typical of benign or malign neoplasm of the soft tissue of oral cavity. Only the use of a special clinical test, permitted the possibility to diagnose the exceptional case of masseter muscle on the left. The surgical therapy, being the neoplasm case benign and well capsuled resulted to be treatable and permitted the definitive resolution of the case
[Diagnostic and surgical problems in a case of post-traumatic retention of a foreign body in the submandibular gland].
No full textWe report a particular case of a traumatically introduced foreign body in the sub-mandibular gland. A breaking object (plastic pen) penetrated, through the anterior oral floor, the submandibular gland. Such foreign bodies should be removed before suturing the wounds, as they can disturb healing and cause problems long after the accident. An adequate history, clinical and imaging studies should reveal the possibility of foreign body penetration and its localization, when it isn't previously removed. We compare the use of ultrasound detection of foreign bodies in soft tissue and conventional plain radiography, computed tomography, and magnetic resonance imaging. The usefulness of US in this kind of research does not justify TC or RM studies and allows a less invasive surgical operation
Surgical and implantation reconstruction in a patient with giant-cell central reparative granuloma
No full textThe giant-cell central reparative granuloma, unlike other giant-cell neoplasias, is mainly found in maxillary bones, particularly in the mandible. We report a patient study of giant-cell central reparative granuloma in the mandible extending from dental elements 34 to 44. The patient underwent excision of a neoplasm and reconstruction of the mandible via an autologous bone graft of the iliac crest. To restore fully, functionally, and aesthetically the masticatory apparatus after verification of graft stability, four osseointegrated implants were fixed, and an "overdenture" prosthesis was then applied, thus finally solving the problem
[A diagnostic protocol in cherubism].
No full textCherubism is a rare hereditary maxillo-facial pathology with unknown pathogenesis. The purpose of the present study is to describe a correct diagnostic approach to cherubism, especially for the differential diagnosis with other maxillo-mandibular cystic diseases. Therefore, the typical clinical, radiological, genetical and histopathological aspects of this pathology are examined. Moreover, an adequate therapy for the cases examined in this study is suggested
ESITI ALGICO-DISFUNZIONALI DELLE FRATTURE CONDILARI
No full textthe aim of this study was to evaluate the presence of articular and muscular pai in patients with surgically or conservatively treated unilateral or bilateral condylar fractures. the Authors show that the alterations deriving from condylar fractures need to be evaluated not only on the basis of the examination of all the element of the stomatognathic apparatus, but also by considering pain and disfuncyional symptoms of TMJ. as well as indirect symptoms such headache or neck pains. Furthermore, they underline the importance of correctly diagnosing of the TMJ modifications induced by a trauma, and or performing clinical and instrumental examinations in both the short and the long term in order to ensure that not all of the changes in the codified control parameters, or direct or indirect symptoms, are automatically attributed to the fractures itself
Mandibular ameloblastoma: Analysis of surgical treatment carried out in 60 patients between 1977 and 1998
No full textAmeloblastoma, a benign tumor of odontogenic type, represents 10% of all tumors of the jawbone. It is localized in the mandible in 80% of cases and in the upper jaw in the remaining 20%. In every case, the selection of the surgical treatment to be applied must consider some fundamental elements, including the age and general state of health of the patient, the clinicopathological variant, and the localization and extent of the tumor. In addition, it is necessary to evaluate whether the neoplasm to be treated is a primitive lesion or a recurrence. Although ameloblastoma has relative histological characteristics of benignity, this neoplasm has a high percentage of local recurrence and possible malignant development when treated inadequately. The aim of this study was to carry out a follow-up of 60 patients treated for ameloblastoma of the mandible between 1977 and 1998, analyzing the problems faced in removing this benign neoplasm and those concerning reconstruction of the surgical defect
Evaluation of the esthetic results of a 40-patient group treated surgically for dentoskeletal class III malocclusion
Get PDFA dentoskeletal Class III malocclusion results in unesthetic alterations of the soft tissues, which may cause psychologic and interpersonal problems. Surgical treatment, if based on cephalometric evaluations alone, can result in inadequate correction of facial esthetics. The aim of this paper is to discuss the esthetic needs observed in surgical planning of a group of 40 Class III patients and to compare the presurgical esthetic parameters with those recorded in the sixth month of follow-up. To obtain the proper esthetic result and to restore proper stomatognathic functionality, surgical treatment planning required the integration and correction of skeletal cephalometric planning. In 24 of the 40 patients, the skeletal and esthetic planning were in agreement with each other. In the remaining 16 patients, the correction of skeletal planning with the esthetic planning was necessary to obtain the correct esthetic and functional restoration. In all patients, esthetic, radiographic, and functional analysis at the sixth month of follow-up revealed the restoration of correct facial esthetics in the vertical, transverse, and sagittal planes; no temporomandibular joint problems; and a high degree of personal satisfaction regarding the esthetic and functional result obtained, including improvements in social life and in masticatory function. Cephalometric indications should always be compared with esthetic clinical indications and, possibly, the skeletal planning must be corrected by the esthetic needs, so that esthetic and functional success can be reached at the same time
[Parapharyngeal involvement in neoformation of the deep parotid lobe].
No full textThe parapharyngeal space can be often interested by the extension of neoplasms starting at the deep lobe of the parotid gland level. According to many international authors, usually benign neoplasm originating at the parotid gland, tend to grow in the above mentioned area, while malignant tumors invade more easily the infratemporal fossa. Several diagnostic methods and ways of approaching the benign tumors of the parapharyngeal space have been proposed over the years. Personal experience at the Maxillo-Facial Department of the University of Rome "La Sapienza" and a typical clinical case for the diagnostic approach and surgical technique used by the authors, is described
Surgical treatment of fibrous dysplasia of the cranio-maxillo-facial area. Review of the literature and personal experience from 1984 to 1999
No full textOBJECTIVE: The aim of this study is to report personal experience on the evolution of the therapeutical approach and surgical treatment in 66 patients with fibrous dysplasia (FD) of the cranio-maxillo-facial area.
METHODS: From January 1984 to December 1999, 66 cases of FD of the cranio-maxillo-facial area were diagnosed. 21 patients were still growing (under 17 years), while 45 were adults (over 17 years). 50 (75.7%) patients showed FD in monostotic form; 15 (22.7%) patients showed FD in polyostotic form; one (1.51%) patient affected by Mc Cune-Albright Syndrome presented the involvement of the left hemimandible. In 24 (36.3%) patients the clinical onset of the disease was insidious, lacked evident symptomatology and the diagnosis was fortuitous. The remaining 42 (63.6%) patients showed different signs and symptoms according to the location of the pathology.
RESULTS: In this time the patients who underwent surgical treatment showed the resolution of the functional and aesthetical problems; the patients who did not undergo surgical treatment, in relation to age and type of pathology, showed an arrest during clinical and radiographic checks.
CONCLUSIONS: We have pointed out the importance of a careful differential diagnosis of fibrous dysplasia with other pathologies with clinical and radiographic conditions similar to it and the importance of a correct surgical planning, carried out according to the patient's age, location, mono or polyostotic form of fibrous dysplasia and to the presence or absence of functional limitations, and aesthetic problems. Further-more we have pointed out the great possibilities of reconstruction of the surgical defects deriving from the utilization of autologous bone grafts and the benefits deriving from the introduction of the internal rigid fixation for the stabilization of these grafts in the surgical defects
