Surgery of the naso-frontal angle.
The naso-frontal angle is one of the features that most markedly determines the morphology of the human face. Two main morphological elements must be taken into consideration: the slope of the forehead and the line of nasal dorsum. For a balanced physiognomy, nevertheless, it is necessary to achieve a correct interaction of the length and width of nasal pyramid, the naso-labial angle, and the chin. Closer examination of the naso-frontal angle shows that a cranial or caudal shift in its position affects the length of the dorsum; however, the fundamental aspect characterizing the naso-frontal angle is its width: it may be normal, too wide, or too narrow. Turning to surgical correction, the authors state that it is easier to modify an over-narrow angle, than one that is too wide. The authors show the single surgical techniques adopted for the correction of the angle, emphasizing the personal method applied to the overwide angle.
