Primary headache and orthognathorhinodontia in childhood

The aim of the research was to study the interrelationship between the primary neurovascular headaches, the various levels dimension of nasal pyramid and the rapid palatal expansion. Twenty-five patients, of both sexes and on developmental age, were studied before and after the rapid palatal expansion. All patients showed palatal hypoplasia and were suffering from primary neurovascular headache. The research was based on the cephalometric and rhinomanometric data. The radiographic documentation of each patient consisted of three postero-anterior teleradiographic projection; the first before application of the disjunction device, the second immediately after disjunction and the third at the end of the contention period. The rhinomanometric evaluation studied the reduction of nasal resistance values before and after palatal expansion. In all patients a constant increase in the values relating both skeletal and dental structures was observed. The nasal septum, if deviated, appeared straightend. The nasal resistances were decreased. The concomitant headache symptomatology presented resolution or recovery in the 98% of treated patients. The results should confirm the hypothesis of the central-peripheral theory of "primary headaches" and the possibility to treat the primary headaches by rapid palatal disjunction in eliminating the stenosis at various levels of nasal pyramid.
