Unusual surgical approach in a bilateral case of mandibular buccal infected cyst.

In the new edition of WHO's "Histological typing of odontogenic tumors", the mandibular infected buccal cyst, that is associated with the lower first or second permanent molars, is considered a paradental cyst as well as the inflammatory collateral cyst, which is usually related to the lower third molar. The lesion occurs on the buccal and lateral aspects of the roots of mandibular molars with vital pulp, at the eruption time, in children aged between 6 and 10 years. The inflammation is always present in these cysts and may have an important role in their pathogenesis because it stimulates hyperplasia and cystic change of the reduced enamel epithelium or the epithelial cell rests of Malassez. The authors report the case of a 7-year-old girl, in whom both first mandibular molars were affected by an infected buccal cyst. A different surgical approach was performed with marsupialization on the left side and cystectomy on the right side. The case reported here seems to be interesting because it is the second well documented case of bilateral mandibular infected cyst associated with unerupted molars and because the adopted treatment differs from the therapeutical approach suggested in the literature. A 6-year follow-up demonstrates a correct dental and bone evolution on both mandibular molar sides.

Langerhans' cell histiocytosis in adults: a clinical and therapeutic analysis of 11 patients from a single institution.

BACKGROUND: Langerhans' cell histiocytosis (LCH) is a rare disorder of uncertain etiology, characterized by a wide clinical spectrum and varied behavior. METHODS: This retrospective study analyzed 11 adult patients with a diagnosis of LCH observed at the study institution between April 1988 and March 1993. RESULTS: Based on the sites and extent of disease at diagnosis, patients were divided into four categories. Group A was comprised of four patients with unifocal bone disease who had surgical curettage. At last follow-up only 1 patient was in continuous complete response (CCR) at 29+ months. The other 3 patients recurred at 3, 12, and 30 months, respectively, after surgery and at last follow-up were found to be in CR at 16+, 48+, and 124+ months, respectively, after therapy with vinblastine (VBL) and high dose methylprednisolone (HDMP). Group B was comprised of three patients with multifocal bone disease. Two of these patients received VBL + HDMP; at last follow-up, 1 patient was in CCR 8 months after completion of therapy, and the other developed progressive disease 11 months later. The third patient was treated with interferon (IFN) and at last follow-up was in CCR at 35+ months. Group C was comprised of 2 patients with bone and visceral disease who were treated with etoposide (VP-16) + HDMP; at last follow-up, 1 patient was in CCR at 42+ months and the other patient, who had isolated vulvar recurrence 16 months later, was in CR with treatment with local IFN. Group D was comprised of two patients with lung and lymph node involvement, one of whom was treated with VP-16 + HDMP and the other with cyclophosphamide, doxorubicin, vincristine, and prednisone; at last follow-up, both were in CCR at 30+ and 71+ months, respectively. CONCLUSIONS: VBL + HDMP showed efficacy in patients with bone disease, in particular those treated for recurrent LCH after surgery. Therapy with VP-16 and HDMP was successfully employed in patients with visceral disease. IFN was effective both for localized disease and in patients with multiple bone lesions.

[Removal of fractured cylindrical implants].

The implant fracture is a rare but significative complication which requires a specific treatment for the surgical removal of the fractured fixture and the modification of the initial prosthetic plan. On the basis of the most recent studies and of a case personally observed in which both the osteointegrated supporting implants of a maxillary overdenture were fracturated, epidemiological, etiopathogenic, diagnostic and therapeutical aspects of this complication are analyzed. Clinical situations most at risk are emphasized, including implant-supported maxillary overdenture, and the major etiologic factors, represented by defects in implant design or material and physiologic or biomechanical overload. The diagnostic criteria are described along with the three therapeutical possible options: 1) removal of the fractured implant, replacement of the implant and refabrication of the prosthesis; 2) modification of the existing prosthesis leaving the fractured portion of the implant in place; 3) modification of the fractured implant and refabrication of a portion of the prosthesis. Three surgical removal technics are then illustrated (block-section, vestibular approach, occlusal approach), with the emphasis on the one choosed in the case examined, in which the ostectomy around the remaining fixture has been carried out with a trephine drill in order to contain the bone loss.
