Radiological Anatomy


The area of the maxillary antrum in Waters' view has been measured in 68 patients using a mechanical planimeter. The mean area was 6.04±0.25 cm2. The part of the antrum lateral to the innominate line (defined as the paratemporal segment) has a mean area of 0.72±0.07 cm2. The latter diminishes in small antra and approches zero when the total antral area falls below 3.48 cm2. It is proposed that the innominate line (Stenvers), or its extension, descends lateral to the field of the small maxillary sinus and may be used as an additional sign of such abnormality.

Segment paratemporal du sinus maxillaire: Un nouvel élément de mesure de la taille du sinus


La surface du sinus maxillaire étudiée en incidence de Waters a été mesurée chez 68 malades en utilisant un planimètre mécanique. La surface moyenne était de 6,04±0,25 cm2. La portion du sinus située en dehors de la ligne de Stenvers (définissant le segment paratemporal) avait une surface moyenne de 0,72±0,007 cm2. Cette dernière diminue avec la taille du sinus et approche une valeur nulle lorsque la surface totale du sinus est inférieure à 3,48 cm2. Les auteurs proposent que la ligne de Stenvers ou sa situation en dehors de la projection d'un petit sinus maxillaire soit utilisée comme un signe supplémentaire de cette anomalie.
