How to Pronounce Mastoid Antrum

Say it like this: MAS-toyd AN-trum. The first word rhymes with 'fast void,' and the second word sounds like 'ant room' without the 'o' sound. The stress falls on the first syllable of each word: MAS and AN.

Many people accidentally stress the second syllable and say 'mas-TOYD' instead of 'MAS-toyd.' Another common mistake is pronouncing 'antrum' like 'an-TROOM' when it should be 'AN-trum' with the stress on the first syllable.

The word breaks down like this: mas-toid (2 syllables) an-trum (2 syllables), for a total of 4 syllables. Written out: MAS-toid AN-trum.

A doctor might say: 'The scan shows inflammation in the mastoid antrum.' Or: 'The mastoid antrum communicates with the middle ear.' These sentences simply describe the location or structure being discussed, not any condition or problem.

Yes, healthcare workers often just say 'antrum' when the context makes it clear they mean the mastoid antrum. You might also hear it called the 'tympanic antrum,' which is another correct anatomical name for the same structure.
