Question: are the tear ducts connected to the sinuses?
Answer: Tears drain into the puncta, located in the inside corners of your upper and lower eyelids. Your eyelids have small canals (canaliculi) that move tears to a sac where the lids are attached to the side of the nose (lacrimal sac). From there tears travel down a duct (the nasolacrimal duct) draining into your nose.
