Frons (Forehead) – Meaning and Usage in Medical English

👁 What Does “Frons” Mean?

The frons is the forehead: the part of the face between the eyebrows and the hairline. It lies over the frontal bone of the skull and the frontal sinuses.

The word is Latin for “forehead” or “front”. You will rarely see frons alone in notes; instead, the adjective frontal attaches to the bone, sinus, muscle and lobe beneath it.

🔍 Clinical Usage

The forehead and its frontal structures come up in emergency, ENT, neurology and dermatology:

• forehead laceration — a very common injury in falls, often closed with sutures or skin glue
• frontal headache — pain felt across the forehead
• frontal sinusitis — infection of the sinuses behind the forehead
• frontal bossing — an unusually prominent forehead, noted in some genetic and growth disorders
• frontal lobe — the part of the brain behind the forehead

Common collocations include:

• laceration to the forehead
• frontal swelling / frontal hematoma
• tenderness over the frontal sinuses
• forehead wrinkles (frontalis muscle)

Here’s a natural clinical example:

“3 cm laceration to the left forehead following a fall; no loss of consciousness.”
→ Meaning: The patient fell and has a 3-centimeter cut on the left side of the forehead, but did not pass out.

🗣 Pronunciation

FRONZ — one syllable. Frontal is FRUN-tul, stress on the first syllable.

💡 OET Tip

With patients, always say forehead. In writing, forehead is perfectly acceptable for the location, while frontal goes with named structures (frontal bone, frontal sinus). Don’t confuse frontal (forehead) with frontal plane (a body section dividing front from back).
