[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.
