Hypoplastic or absent mandibular frenulum: a new predictive sign of infantile hypertrophic pyloric stenosis.
Among 25 patients with hypertrophic pyloric stenosis, a hypoplastic or absent mandibular frenulum was noted in 92%, compared with 1.6% of 319 control infants (P <.001). This previously unrecognized sign may prove helpful in identifying newborns at risk of developing the disorder.
