In short. Feeling for the vessels, following the course of one nerve, measuring the depth of the compartment and reading the bone beneath it. What the consultation does here.

Key points

  • Which of the three causes your hollow has, whether the placement will sit beneath the fascia or above it, roughly how many sessions the plan involves and at what interval, what the review at four weeks is for, and what would make the plan stop.
  • If those five things are not clear at the end of the consultation, the assessment is not finished.

A temple assessment looks at four things that do not appear in a photograph: where the vessels run, how the nerve that lifts the brow is working, how thick the tissue is over the bone, and what shape the bone is. Each changes what can safely be done, and all four are settled before any material is discussed.

Palpation of the vessels

The superficial temporal artery and its branches are felt for in front of the ear and above the cheekbone, and the veins that cross the same region are mapped. Their positions vary between people, so this is done by hand on the day rather than assumed from a diagram. The result decides the entry points, the direction of travel and often the choice of instrument.

The course of the temporal branch

The temporal branch of the facial nerve crosses this region on its way to the brow, and it is neither visible nor palpable. Its likely course is inferred from landmarks — the ear, the cheekbone, the outer orbital rim — and the safe placement follows from that. The way the brow lifts is recorded before treatment as a baseline, because a change afterwards is only meaningful against what was there at the start.

The depth of the compartment and the shape of the bone

How much tissue sits over the temporal fossa decides which plane is available and how much material a given change needs. The bone decides something else: whether the hollow is tissue that has been lost or a frame that was always recessed. Where the bone is the reason, the honest description of the result is a change to the covering rather than to the structure.

What you should leave the assessment knowing

Which of the three causes your hollow has, whether the placement will sit beneath the fascia or above it, roughly how many sessions the plan involves and at what interval, what the review at four weeks is for, and what would make the plan stop. If those five things are not clear at the end of the consultation, the assessment is not finished.

What the assessment rules out

Part of the examination is looking for reasons not to proceed. Active infection or broken skin over the area, a brow that has clearly descended so that the hollow is a shadow rather than a deficit, a temple still changing with weight or illness, and a history of frequent headache are findings that change the plan or end it. Recording them is the part of the consultation that does the most work.

Findings that change the plan

  • The hollow is deepest directly under a brow tail that has moved down.
  • The temple is still changing with weight loss, illness or treatment.
  • There is active infection, broken skin, or a dental or sinus problem in the same area.

Why the plane decides the result is set out in Why Depth Decides the Result in Temple Filler. The anatomy the assessment works around is described in Vessels, Nerves and the Temple Danger Zone.

Frequently asked questions

Why does the clinician feel the temple before deciding anything?

Because the vessels in this compartment are close to the surface and their positions vary between people. Feeling for the pulse of the temporal artery in front of the ear and mapping where the veins run is how the entry points and the plane are chosen. It is done with the fingers before any material is considered.

What is the brow test in an upper-face assessment?

You are asked to raise the brow while the clinician watches and feels. That records how the nerve that lifts the brow is working before treatment, so that any change afterwards can be compared with a baseline rather than with a memory. It takes a few seconds and it becomes part of the record.

Does the assessment involve photographs?

Standardised photographs from more than one angle are part of planning rather than a formality, because a temple change is easier to see from an angle than from the front. They are what the review at four weeks is judged against, and they are how a real change is distinguished from the way the face felt during the first week.

Risks & Limitations

  • The temple is crossed by named vessels in a small space: the superficial temporal artery and its branches, the vein known as the sentinel vein near the outer orbital rim, and the deep temporal vessels beneath the fascia. Material entering an artery can travel, and because the frontal branch of the superficial temporal artery communicates with the vessels around the eye, skin loss and — rarely — loss of vision are possible. This is time-critical rather than cosmetic.
  • The temporal branch of the facial nerve crosses the same region on its way to the brow. If it is affected the brow will not lift on that side. Most such weakness improves over weeks to months, and a proportion does not recover fully, which is why the way the brow lifts is recorded before treatment rather than only examined afterwards.
  • Deep placement beside the temporalis muscle is commonly followed by a dull pressure headache that settles over a day or two, and by an ache on opening the mouth wide or chewing hard. A headache that is severe, one-sided in a new way, or worsening after the first days is not ordinary recovery and should be assessed.
  • Adding volume to the temple does not lift a brow that has descended. It fills the shadow beneath the brow tail and changes how the upper face reads, and the position of the brow is unchanged. Where the distance between brow and eye is the complaint, the answer is an operation rather than an injection.
  • Swelling and bruising, firmness and small lumps in the first weeks, asymmetry, nodules and delayed inflammatory reactions can occur. Every result is temporary, the material is not fully cleared between sessions, and only the reversible class can be broken down at all.

When to Seek Care

  • Any change in vision, including blurring or a patch of lost sight — seek emergency care immediately.
  • Severe pain out of proportion to the injection, or pain that is worsening rather than settling.
  • Skin turning white, grey, mottled or dusky anywhere near the treated temple, the forehead or the eye.
  • A brow that will not lift on one side, or a headache that is severe or worsening after the first few days.
  • Swelling that is increasing after the first few days rather than settling, or fever with spreading redness, warmth or discharge.
