Gli osteomi dei seni paranasali: revisione della letteratura e casistica personale
The sinusal osteomas: a review of literature and personal cases. The osteoma is a osteogenetic benign tumour formed by a fully developed bone, characterized by a slow growth, which, as far as the maxillo-facial region is concerned, shows to be frequently located in the paranasal sinuses. The osteoma originates from one of the sinus walls and spreads into the sinus cavity itself producing symptoms related to a lesion space occupying. In the present report, taking into consideration 4 personal cases, some literature datas are examined concerning the epidemiology, clinical behaviour and especially the therapeutic implications to be adopted by the surgeon in the presence of sinusal osteoma
[The oral manifestations during Kaposi's disease].
Kaposi's sarcoma is a rare neoplastic disease of the vascular system with multiple foci. Oral manifestations are uncommon. The authors report an oral localization of a Kaposi's disease; the etiopathogenesis, the clinical features and the treatment of such lesions are discussed
Reconstruction of the orbital walls in surgery of the skull base for benign neoplasms
Surgery for benign neoplasm extending into the orbital roof requires immediate reconstruction to avoid complications, which include transmission of the cerebral pulse to the globe, bulbar dystopia, diplopia, and fibrosis of the oculomotor muscles. Many alloplastic materials have been employed for such reconstruction, but currently most authors agree that autologous bone graft is the best option. Using calvarial bone in adults and split ribs in children, we have operated on eight patients for fibrous dysplasia (five cases), neurofibroma (two cases), or meningioma (one case). After a median follow-up period of two years and six months, good morphology of the orbit was maintained with no ocular symptoms
L'utilizzo del lembo di muscolo temporale nella chirurgia dell'ATM: tre anni di esperienza
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
