[Congenital piriform aperture stenosis and odontogenic disorders].

Purpose: We had for objective to assess odontogenic disorders associated to a congenital piriform aperture stenosis and to study their various presentations.
Methods: Twelve patients presenting with a congenital piriform aperture stenosis, 1 week to 3 months of age, were retrospectively included from 1998 to 2008. All patients underwent an initial CT scan to evaluate the temporary dental germs.
Results: Deciduous dental germs were abnormal in 75% of the cases. Thirty-three percent had a single median maxillary central incisor.
Discussion: The concept of solitary median maxillary central incisor syndrome makes for a more pathophysiological approach of this type of disease, with various clinical presentations, corresponding to various levels of severity of a same pathological process.
