so basically what this means is your child has some polyps or cysts in his sinuses which are cavities beyond or beside the nasal passages. the maxillary sinus is the cavity behind the cheek. the sphenoid sinus is located more toward the upper bridge of the nose sort of below the inside corner of the eye. polyps in these areas are common but they can block mucus from draining out of the sinus cavities which can cause a headache. nasal polyps are not cancerous. they may be treated with corticosteroid nasal spray. if that doesn't work polyps can be removed surgically. it's a pretty simple surgery that's usually done on an outpatient basis. i hope this helps!
my 11yo has chronic headaches. ct scan shows 1. 4cm polyps/cysts inright maxillary and sphenoid sinuses. any info?
