Maxillary Retention Cyst and Chronic Migraine

My 15 year old daughter has been suffering with a migraine that has lasted 442 days. An MRI back in 2024 revealed that she has a right maxillary mucous retention cyst. We were told by an ENT it was not related to the migraine. Pediatric neurology has been unable, through medications and sphenopalatine ganglion blocks, to break the migraine cycle. We have pursued elimination diets, acupuncture, laser treatments, physical therapy, and osteopathic manipulation and nothing has worked. Could the retention cyst actually be causing this migraine pain?
