Morphology
The meaning is directly compositional: 'paranasal' (located near the nasal cavities) combined with 'sinus' (an air-filled cavity) yields 'air-filled cavities near the nose.' Although medical, the components transparently indicate location and referent, so a learner who knows both parts can infer the MWE meaning.
Etymology
The term paranasal sinus is built from parts: para- means 'near', nasal means 'nose', and sinus means 'space'. So paranasal sinuses are the small air-filled spaces in the bones 'near the nose', which is why doctors use this name for those cavities.
