Strutture anatomiche craniofacciali: correlazioni tra cefalometria in proiezione laterolaterale e posteroanteriore = Cranio-facial structures: correlations between cephalometry in latero-lateral and postero-anterior projection

Abstract

Scopo del lavoro. Lo scopo di questo lavoro consiste nel valutare se esiste una relazione fra dimensioni lineari di alcune strutture anatomiche craniofacciali in proiezione laterolaterale e posteroanteriore. Materiali e metodi. Sono stati presi in considerazione i tracciati cefalometrici condotti sulle teleradiografie del cranio in proiezione laterolaterale e posteroanteriore di 100 pazienti che si sono presentati al Reparto di Ortognatodonzia dell’Università degli Studi di Milano. Sulla teleradiografia del cranio in proiezione laterolaterale sono state considerate le dimensioni lineari della base cranica (S-N), del mascellare superiore (SNP-A) e della mandibola (GO-ME); sulla proiezione posteroanteriore sono state analizzate una distanza rilevata a livello della base cranica (PASdx-PASsx), una del mascellare superiore (MXdx-MXsin) e una mandibolare (GOdx-GOsx). Risultati. L’analisi delle dimensioni lineari di alcune strutture anatomiche craniofacciali in proiezione laterolaterale e posteroanteriore consente di individuare una relazione tra le strutture considerate. Tuttavia le teleradiografie del cranio in proiezione laterolaterale e posteroanteriore forniscono una rappresentazione bidimensionale di una struttura tridimensionale. Conclusioni. È possibile individuare una relazione lineare fra le misure delle stesse strutture anatomiche in due proiezioni diverse. I dati ottenuti sono considerati significativi a livello del mascellare superiore e della mandibola, non per la relazione PASdx-PASsx e S-N. Infatti questi valori non rappresentano le stesse strutture anatomiche, bensì sono solo misure di controllo fra strutture diverse.

Aim of the work. The aim of this work consists in evaluating the relationship between linear dimensions of some craniofacial structures in lateral and frontal vision. Materials and methods. Cephalometric tracings done on lateral and frontal radiography of 100 patient of the Orthodontic Department (University of Milan) were analyzeded. On lateral teleradiographs, the linear dimension of cranial base (S-N), maxilla (SNP-A) and mandible (GO-ME) were considered. On frontal tracing the same measurement were performed at a definite distance from: cranial base (PASdx-PASsx), maxillary bone (MXdx-MXsin) and mandibular bone (GOdx-GOsx). Results. The analysis of linear dimensions of some anatomic cranio-facial structures in lateral and frontal projection allows to individuate their relationship. However, lateral and frontal radiographs gave a bidimensional representation of a tridimensional structure. Conclusions. it is possible to individuate a linear relationship between the measures of the same anatomic structures in two different projections. Data obtained are significative for the upper maxilla and lower jaw, but not for PASdx-PASsx and S-N. In fact, these values don’t represent the same anatomic structures but they are control values among different structures.
