Sunken Temples: Causes, Assessment & Treatment Options
Hollowing at the temple is read by almost everyone who has it as a loss of volume, and for many people it is one. For others it is the shape of the bone underneath, a narrow temporal fossa that was there in childhood, or an overall loss of facial fat that has nothing to do with the temple in particular. The distinction matters because the answers differ: volume replacement suits one of those, and doing nothing is the honest answer to another. This site is about naming which one you have, what the anatomy of this small area allows, and where every route stops.
Patient education reviewed by Tongchun Mao, MD. Change at the temple on one side only, a new hollow after injury or illness, or hollowing with unexplained weight loss should be assessed medically before anything cosmetic is considered.
Six things that produce a hollow at the temple
Four of these account for most temples that are examined. The fifth and sixth are the reason the assessment comes before the plan, and the reason a temple is not simply filled on request. Naming the cause is most of the decision.
Deflation of the deep temporal compartment
The temple holds a fat compartment that sits deep, beneath the muscle that closes the jaw. It deflates with age in the same way the fat of the cheek and the eyelid does, and because it lies deep, its loss changes the contour of the whole region rather than just the surface. This is the commonest cause of a temple that hollows in adult life, and it usually begins in the thirties or forties rather than the fifties.
Bony change in the temporal fossa
The bone beneath the temple is not fixed. The fossa remodels across adult life, and the region loses projection as the skull changes, independently of what the fat above it is doing. Bone-driven change behaves differently from fat loss: it is gradual, it is symmetric, and no amount of volume placed above it recreates the earlier frame.
Low facial fat generally
Some faces have little fat everywhere, and the temple shows it early because the compartment there is small to begin with. Genetics, a long illness, an eating disorder, endurance training and major weight loss all produce this pattern. Where the whole face is lean, treating one region in isolation tends to look like a change to one region rather than an improvement to the face.
A narrow temporal fossa that was always narrow
A proportion of people are born with a temporal fossa that is narrow or deeply set, and the hollow has been present, unchanged, for as long as they can remember. It is a shape rather than a loss, nothing about it progresses, and it is the presentation where the honest answer is most often that nothing should be done. Photographs from ten years ago are what settle it.
Hairline shape and brow position
The temple is defined as much by its borders as by its surface. A temporal hairline that has receded exposes more of the region and makes a hollow read deeper, and a brow tail that has descended crowds the area from above. Both change what the temple looks like without any change in the tissue beneath, and both are visible in a photograph.
Earlier treatment nearby
Volume placed in the cheek, the brow or the midface changes how the temple is read against its neighbours, and an earlier temple treatment that was overfilled, uneven or placed too superficially can itself become the complaint. Assessment therefore starts with what has already been done and when, because the timing changes the options.
When a hollow at the temple is not a cosmetic question
Almost every temple hollow is an appearance concern and the assessment is unhurried. A small number are the visible part of something else, and the difference is made by how the change arrived rather than by how deep it looks. Change on one side only is the finding that matters most, because the ordinary causes are broadly symmetrical even when they are not perfectly matched. A hollow that appeared over weeks rather than years, a hollow after a head injury or after surgery to the area, and a temple that has changed alongside unexplained weight loss, fever, night sweats or pain all need a physician rather than an aesthetic consultation. Tenderness over the temple, difficulty opening the mouth or chewing, or a visible or palpable lump in the region belong with a doctor as well, because the muscle that closes the jaw lies directly beneath the compartment that hollows. Headache with scalp tenderness in someone over fifty is a reason to seek care promptly rather than to book anything. None of this means treatment is forbidden; it means the cause has to be established first and the timing has to be right. Where none of it is present, the ordinary conversation about fat, bone, hairline and proportion can begin on a sound footing, and that conversation is what the rest of this site is about.
How the temple is examined, and why it takes longer than the treatment
The temple is a small area with an unusual concentration of structures that matter. The examination is longer than the area looks because the answer has to be a cause rather than a shape, and because the structures beneath decide what is safe to do at all.
Naming the vessels before anything else
Two named vessels run through this region and both are examined and, where it helps, mapped before any plan is made. The artery crosses in front of the ear and passes over the cheekbone, and the vein that drains the temple runs deep in the region. A plan for this area is made around those, which is why the assessment is a mapping exercise rather than an inspection.
The nerve branch that moves the brow
The branch of the facial nerve that lifts the eyebrow crosses the cheekbone on its way to the forehead, and it travels in the layer just beneath the skin in this region rather than deep among the muscles. That is the reason a temple is treated with more caution than its size suggests, and the reason an injector who works here often knows where it runs on a particular face.
Weighting fat against bone
The examiner is trying to establish whether what has changed is the soft tissue, the bone beneath it, or both. Comparing old photographs with the face in the room does most of this work. A hollow that has been stable for twenty years and is present in a childhood photograph is a shape; a hollow that has appeared over five years in a face that was once full is a loss, and the two are managed differently.
Reading the borders
The temporal hairline is noted, along with the position of the brow tail, the projection of the cheekbone and the width of the face at the level of the temple. These are not incidental: a receded hairline and a descended brow change how a hollow reads, and both can be addressed in their own right. Some patients who arrive asking about the temple leave with a plan that concerns the brow.
The history, and what has already been done
The assessment covers when the change started, whether it is the same on both sides, weight change over the past two years, illness, training, and any previous treatment to the temple, cheek or brow, including when it was given. The temple is one of the areas where an earlier treatment is most often part of the current complaint, and the timing decides whether anything can be done now.
What the assessment deliberately leaves out
It does not decide on a product, a volume or a technique, and it does not take a photograph as a substitute for looking at the face. A plan made from a photograph alone is a plan made without the two observations that matter most here: how the region behaves when the face moves, and where the vessels and the nerve branch sit on that particular face.
The ladder, from doing nothing to fat transfer
The rungs run from measures that cost nothing to an operation, and the important part is not the order but the matching. Mild hollowing that reads well, is stable and is present in old photographs is a finding rather than a problem, and doing nothing is a legitimate answer at every rung, not a failure to decide. Below the injectable rungs sit the reversible causes: weight that is still falling, an untreated illness, poor sleep and dehydration all change how the temple reads, and addressing them costs nothing and is worth doing first because it changes the baseline the rest is judged against. Photographic and lighting changes come next, honestly described: they do not change the temple, they change how it is seen, and for a mild hollow that is sometimes enough. Hyaluronic acid filler placed deep into the compartment is the rung most people mean by treating a temple, and it belongs to the cause where the deep compartment has deflated. Collagen-stimulating injectables add volume gradually over months and are less immediately reversible, which is the trade a patient accepts in exchange for a slower, softer change. Autologous fat transfer sits at the top: it needs a donor site, it is a surgical procedure with its own recovery, and its take is less predictable than any injectable, which is why it is a later rung rather than a default. The ceiling does not move: no rung restores the temple a patient remembers, and this region shows overfilling sooner than most, because the compartment is shallow and its borders are visible.
Four ways people make this worse
The first is to have a temple filled when what is actually present is bone. Where the fossa is narrow or deeply set and has been that way for life, adding volume above it changes the surface without changing the frame, and the result reads as a fuller face rather than as a corrected temple. The second is to treat the temple in isolation on a face that has lost fat everywhere, which produces one region that looks younger than the rest of the face and draws attention to the difference. The third is to judge the result in the first fortnight. This region holds fluid after any injection, the swelling settles unevenly, and a decision made at ten days is a decision made on a face that is not the final one. The fourth is to accept a plan for the temple when the real complaint was never the temple. A receded hairline, a descended brow tail, an unprojected cheekbone and a face that is lean overall all read as temporal hollowing, and each has its own answer. None of these mistakes is rare, and every one of them is easier to avoid at the start than to repair afterwards. Each begins with a treatment chosen before the cause was named.
If the decision moves toward treatment
This site deliberately stops short of describing how the temple is treated, because the technique and the anatomy it depends on are set out properly elsewhere in this cluster. The regional hub for facial aesthetic surgery covers the upper face as a whole, and the assessment and the operative detail are described on Dr. Mao’s own site. The injectable route to this region is explained at category level under temple filler, and the surgical volume route under fat grafting. Where the temple is one part of a face that has lost fat generally, the wider problem is described under facial fat transfer and facial change after weight-loss medication. Where the change is driven by the brow or the hairline rather than by the temple, that belongs with the guides on brow position instead. Before any treatment, quality and surgical safety describes how safety is organised inside the hospital, and appointments explains how to arrange an assessment.
Sunken Temples: Causes and the Ladder in Order
Possible causes on the left and the ladder on the right, from least to most invasive. Note that the first rung is a review rather than a treatment, that two of the six causes are not volume problems at all, and that the last line is the ceiling no rung reaches.

Frequently asked questions
How do I know whether my temples have hollowed or were always like this?
Old photographs settle it better than anything else. A temple that looks the same in a picture from fifteen or twenty years ago, in the same light and at a similar weight, is a shape rather than a loss, and nothing about it will progress. A temple that has clearly changed while the rest of the face has changed with it is a loss. Bring the pictures with you, because the difference between the two decides whether treatment is even relevant.
Is filling a temple a straightforward treatment?
It is a small area, and that is exactly why it is not straightforward. A named artery crosses in front of the ear and over the cheekbone, a vein drains the region deep, and the branch of the nerve that lifts the eyebrow passes through the layer just beneath the skin here. The assessment is longer than the treatment because the plan has to be made around those structures, and it is the reason this site argues for someone who works in this region often rather than occasionally.
Why does the hollow look worse in some photographs than in others?
Because a camera records shadow more starkly than an eye does, and because this region sits in the transition between the lit forehead and the shaded side of the face. A light from directly in front flattens the temple; light from above or from the side deepens it considerably. Two pictures taken on the same day can therefore look like two different faces, which is why lighting is itself one of the rungs on the ladder.
Do I have to start with the least invasive option?
No, and treating the ladder as a queue is a common mistake. Where the deep compartment has clearly deflated and the bone is not the issue, the honest first conversation may be about volume. What the order protects against is the other direction of error: having an operation, or a series of treatments, for a temple that was never a volume problem. The cause decides where you start, not a queue.
What about a hollow temple does no treatment change?
The bone. Where the temporal fossa is narrow or deeply set, part of what you see is the frame of the skull rather than a loss of tissue above it, and adding volume changes the surface without changing the frame. Recognising that early is what prevents a series of treatments that were never going to reach what the patient was describing.
Can a temple hollow be caused by something medical?
It can. Unexplained weight loss, a long illness, an eating disorder and heavy endurance training all reduce facial fat, and the temple shows it early because the compartment there is small. A hollow that has appeared on one side only, or over weeks, or after an injury or an operation to the area, needs a physician rather than an aesthetic assessment, and that comes first.
