La timpanometría revisa el tímpano.

Because timpanometría is a feminine singular noun, so it takes the feminine singular definite article la.

• la timpanometría = the tympanometry
• el tímpano = the eardrum

In Spanish, nouns usually need an article more often than in English, especially in simple statements like this.

Most Spanish nouns ending in -a are feminine, and timpanometría follows that pattern.

So:

• la timpanometría
• not el timpanometría

Also, many scientific or medical terms ending in -ía are feminine:

• la biología
• la anatomía
• la audiometría

Because revisa is the conjugated form of the verb, while revisar is the infinitive.

• revisar = to examine / to check / to inspect
• revisa = examines / checks / inspects

The subject here is la timpanometría, which is third-person singular, so the verb must also be third-person singular:

• La timpanometría revisa el tímpano.

It is the present indicative.

So revisa means:

• examines
• checks
• sometimes is used to examine, depending on context

Spanish often uses the present tense for general facts, definitions, and descriptions of what something does.

Usually, no. This is a very common false friend.

In Spanish, revisar usually means:

• to check
• to examine
• to inspect
• to review

It usually does not mean to rewrite or edit a text the way English revise often does.

So in this sentence, revisa el tímpano means checks/examines the eardrum, not revises the eardrum.

Because tímpano is a masculine singular noun, so it takes el.

• el tímpano = the eardrum

In Spanish, when talking about body parts in a general or medical way, the definite article is very common. Spanish often uses the where English might use the, your, or no article depending on context.

No. They refer to different things.

• tímpano = eardrum
• oído = ear or hearing depending on context
• oreja = outer ear / ear flap

So el tímpano is a specific inner structure, not the whole ear.

They show which syllable is stressed.

• timpanometría → stress on -rí-
• tímpano → stress on tím-

A rough English-style pronunciation guide:

• timpanometría ≈ teem-pah-no-meh-TREE-ah
• tímpano ≈ TEEM-pah-no

The written accent is important because it tells you where the stress goes and sometimes distinguishes pronunciation patterns that would otherwise be different.

Yes. It follows the very common Spanish order:

subject + verb + object

• La timpanometría = subject
• revisa = verb
• el tímpano = direct object

So the sentence structure is very straightforward and natural from a grammar point of view.

Yes. It is a direct medical cognate.

• timpanometría = tympanometry

This is useful because many medical and scientific words in Spanish look similar to English:

• biología → biology
• anatomía → anatomy
• audiometría → audiometry

Just remember that even when the noun looks familiar, the surrounding grammar is still Spanish.

Yes. That is one of the normal uses of the Spanish present tense.

La timpanometría revisa el tímpano can be understood as a general statement about what tympanometry does. Spanish often uses the singular like this for a general or technical description.

So it is not necessarily saying that one specific test is happening right now. It can simply describe the function of the procedure.

It is grammatically correct and understandable, but in medical Spanish a speaker might also say something like:

• La timpanometría evalúa el tímpano.
• La timpanometría examina el tímpano.
• La timpanometría sirve para revisar el tímpano.

So revisa works, but depending on context, evalúa or examina may sound a bit more technical or medical.

Not in normal Spanish. That sounds unnatural and incomplete.

Spanish usually needs the articles here:

• La timpanometría revisa el tímpano.

Dropping both articles would sound more like broken Spanish or note-taking shorthand, not a normal full sentence.
