How to Pronounce Petrotympanic Fissure

Say it like this: pet-roh-tim-PAN-ik FISH-er. The stress falls on the third syllable of the first word (PAN) and the first syllable of the second word (FISH). Think of 'petro' rhyming with 'metro,' 'tympanic' sounding like 'tom-PAN-ik,' and 'fissure' like 'FISH-er.'

Break it into five syllables: pet-ro-tym-pan-ic. The stress lands on the fourth syllable, so it's 'pet-ro-tym-PAN-ic.' Saying it slowly syllable by syllable can help you get the stress in the right place.

'Petro-' comes from Latin and Greek and refers to stone or rock. In this case, it refers to the petrous part of the temporal bone in your skull, which is the hard, dense, rock-like portion.

'Tympanic' comes from the Latin word for drum and refers to the eardrum (the tympanum). The tympanic part of the temporal bone is the section of the skull that surrounds and supports your eardrum.

A fissure is a thin crack or narrow opening, often in bone or tissue. In 'petrotympanic fissure,' it's the small cleft or gap between two parts of a skull bone.

It's a tiny gap or crack in your skull between two neighboring parts of the temporal bone (the bone behind and around your ear). Think of it like a hairline fracture, except it's a normal part of skull anatomy, not an injury.

Many people stress the wrong syllable and say 'PET-ro-tim-pan-ik' instead of 'pet-ro-tim-PAN-ik.' Remember: the stress jumps to the third syllable from the end of the first word.

A doctor might say: 'The chorda tympani nerve passes through the petrotympanic fissure to reach the tongue.' This sentence shows that the term names a specific anatomical passageway in the skull.
