Abstract
Seven patients who had the complete form of mandibulofacial dysostosis were examined to determine the prevalence of nasolacrimal abnormalities. Bilateral inferior punctal atresia (and, by implication, accompanying inferior canalicular atresia) was identified in all seven patients; a 95% confidence interval for the true underlying rate of this finding in mandibulofacial dysostosis is 59% to 100%. Lacrimal surgery was required in only one patient who had coexistent bilateral nasolacrimal duct obstruction and chronic dacryocystitis and who responded well to bilateral dacryocystorhinostomy.
