How to Pronounce Frontal Sinus

Say it like this: FRUN-tal SY-nus. The first part rhymes with 'front,' and the second part sounds like 'sinus' (SY rhymes with 'my'). Put the stress on the first syllable: FRUN-tal.

The stress falls on FRUN in the first word. You say it louder and longer than the other syllables: FRUN-tal SY-nus. A common mistake is stressing the second syllable (frun-TAL), but that's incorrect.

Break it into four syllables: FRUN-tal SY-nus. The first word has two syllables (FRUN-tal) and the second word has two syllables (SY-nus).

'Frontal' comes from the Latin word 'frons,' which means 'forehead.' So 'frontal sinus' literally refers to a sinus cavity located in your forehead area, in the bone just above your eyebrows.

'Sinus' is a Latin word meaning 'cavity' or 'hollow space.' In anatomy, it refers to an air-filled pouch in the bones of your head and face. So a frontal sinus is simply a hollow air-filled space in your forehead bone.

People sometimes say frun-TAL instead of FRUN-tal, or they pronounce 'sinus' as SY-nus when it should sound like 'sigh-nus.' The correct way is to stress the first syllable and say both words clearly: FRUN-tal SY-nus.

Yes, doctors sometimes just call it the 'frontal' sinus, or they use the abbreviation FS. You would say 'F-S' by spelling out each letter, or sometimes in medical writing it appears as 'FS' or 'frontal sinuses' (plural) when talking about both sides.

Other paranasal sinuses include the maxillary sinus, ethmoid sinus, and sphenoid sinus. You might also hear 'sinusitis,' which means inflammation of the sinuses. All of these words use 'sinus,' which means a hollow cavity.

Sure! Here's an example: 'The frontal sinus is one of four pairs of air-filled spaces in your head.' Another example: 'A doctor might examine your frontal sinus if you're having forehead pain.'
