Espansione palatale rapida chirurgicamente assistita (SARPE) in pazienti adulti e tardo-adolescenti.

The authors describe the indications and the procedures of surgical assisted rapid palatal expansion with the showing of a clinical case. The technique described is a classical procedure: the ortodontic treatment follows surgery. The expansion gave the space to place a screw and a ceramic crown to close the space of an agenesia

Mandibular traumatic peripheral osteoma: A case report

An osteoma is a slow-growing, benign lesion comprising mature bone tissue. Osteomas rarely occur in maxillary bones, with the exception of the maxillary sinuses. Various possible etiologies have been proposed, including congenital anomalies, chronic inflammation, muscular activity, embryogenetic changes, and trauma. Here we present a case of an osteoma of the buccal plate of the mandible at the site where a sports-related traumatic injury occurred 15 years earlier. Both conventional and 3-dimensional x-ray examinations were used for diagnosis and preoperative evaluation of the possible involvement of the adjacent anatomic structures. The lesion was treated surgically without complications and the patient made a complete recovery. Histologic tests confirmed the preoperative diagnosis. A review of the international literature is also presente

Solitary fibrous tumours of the infratemporal fossa. Two case reports

Introduction: The solitary fibrous tumour is a rare neoplasm originally described as a pleural tumour. An increasing number of different locations are described in the literature. Among the extrapulmonary sites, head and neck can be involved and particularly the nose, the paranasal sinuses, the submandibular region, the parapharyngeal space and the infratemporal fossa. Material: Two cases, one of a young woman and another of an elderly gentleman are reported, each presenting with a solitary fibrous tumour of the infratemporal fossa. In one case an antero-lateral, transcranio-facial and in the other, a transmandibular approach (without labiotomy) were utilized. In both cases complete excision of the lesion and good cosmetic results were achieved. Results: Both patients were free from the disease for 5 postoperatively. Conclusions: To date, very few cases of solitary fibrous tumour of the craniofacial complex have been observed to enable an accurate prognosis. Thus, treatment and follow-up should be identical to fibrous tumours located in other areas. (C) 2006 European Association for Cranio-Maxillofacial Surgery
