[Original three-dimensional reconstruction of a case of metopism associated with a unilateral complete absence of the left frontal sinus: Clinical interest and review of the literature]

Abstract

Metopism (complete persistence of the metopic suture in adults) is a rare but not exceptional variation of the calvaria. Hypoplasia or aplasia of the frontal sinus may be associated without evident correlation. Nevertheless, a misdiagnosis of these variations may have clinical consequences, especially in a traumatic context. The aim of this paper was to report a case of metopism associated with a unilateral aplasia of the left frontal sinus, originally illustrated with 3D image fusion volume rendering reconstructions.
