Primary Headache Relief in Paediatric Patients Following Rapid Maxillary Expansion: a Prospective Study and Cephalometric Changes Analysis.

Primary headaches (PH) are a group of disorders greatly impairing quality of life, highly prevalent in growing population. Previous studies suggested a rhinogenic involvement in PH episodes. Modifications of nasal cavities and septum take place during rapid maxillary expansion (RME). This study aims to investigate the role of skeletal modifications due to RME on PH episodes.
