Chin & Jawline Surgery

This is not only about a larger or smaller chin. What matters is the relationship of the individual structures to one another.

A chin or jaw correction can therefore pursue different goals. The chin can be changed in projection, height or width. The contours of the lower jaw can be more strongly defined or reduced, depending on anatomy.

At Clinic Selnau in Zürich, we plan these procedures based on your existing facial structure, and always consider the lower face in relation to the profile, nose and neck.

Our Approach

Every lower face is different.

Bone structure, chin projection, jaw angle, soft tissue and the distribution of fat tissue together determine the contours of the chin and jaw.

For this reason, planning does not begin with an ideal jawline or a particular profile. We first consider which anatomical structure is responsible for the perceived proportion.

A less pronounced chin, for example, can make the profile appear unbalanced, even though the nose itself is harmoniously shaped. A less defined jawline, in turn, can result from bone structure, soft tissue, fat tissue, or changes to the neck.

These causes require different treatment approaches.

The aim is not maximum definition. It is to change the chin and jaw so that they fit naturally with the rest of the face.

Chin, Jawline & Profile

The lower face is significantly shaped by the projection and shape of the chin, and the course of the lower jaw.

A chin or jaw correction may be considered for concerns including:

• Reduced or pronounced chin projection
• A chin that appears small or large relative to the face
• Asymmetries of the chin
• Changes to chin height or width
• Poorly defined contours of the lower jaw
• A very wide or dominant jaw contour
• Asymmetries of the lower face
• A wish for more feminine- or masculine-appearing contours
• An unbalanced relationship between the nose, lips and chin
• Contour changes following previous procedures or injury

Not every poorly defined jawline, however, is caused by bone structure. Skin, fat tissue and neck structures can have a significant influence. For this reason, it must first be clarified which anatomical level is actually responsible for the visible change.

Planning & Analysis

A careful analysis of overall facial proportions forms the basis of treatment.

During consultation, we examine your face from the front, in profile, and from a three-quarter view. We assess the projection, height and width of the chin, the course of the lower jaw, and any existing asymmetries.

At the same time, we consider the nose, lips, cheeks and neck.

These structures are closely connected, particularly in profile. A change to the chin therefore influences not only the lower face, but can also change how prominent the nose appears, or how defined the transition to the neck is perceived to be.

Depending on the planned treatment, further imaging may be necessary to assess the bony structures more precisely.

On this basis, a treatment plan is developed that is guided by your existing anatomy and desired proportions.

Chin Correction

The shape of the chin can be changed in different ways.

Where the bony projection, height or position of the chin needs to be corrected, a surgical change to the chin bone can be appropriate. Depending on the starting point, the chin can be repositioned forward or backward, up or down, or adjusted to correct specific asymmetries.

This form of bony chin correction is often referred to as genioplasty.

Alternatively, a chin implant can be used in suitable situations, particularly where additional projection or contour is needed.

Which method makes sense depends on which dimension of the chin needs to be changed, and the existing bone structure.

What matters is not creating the most prominent chin possible. It is a projection and shape that harmonises with the nose, lips, jaw and neck.

Jawline & Lower Jaw Contour

The shape of the lower jaw, too, can significantly influence the character of the face.

The width, angle and course of the jawbone, together with the soft tissue above it, determine how defined or soft the jawline appears.

Depending on the starting point, bony contours can be changed in a targeted way. This can involve stronger definition of certain areas, or the reduction of a very pronounced jaw contour.

Precise analysis of the underlying cause is especially important for jawline changes.

A poorly visible jawline does not automatically result from an insufficiently developed lower jaw. Fat tissue, excess skin, or changes to the neck can also obscure the contour. A bony correction cannot replace such soft tissue changes.

Bone or Soft Tissue?

One of the most important questions in planning is at which anatomical level the desired change should take place.

Where the shape, projection or width of the bone determines the proportion, a bony correction can make sense.

Where, by contrast, mainly fat tissue or skin obscures the jawline, other methods may be more suitable. Liposuction, for example, may be considered for localised fat beneath the chin. For more pronounced changes to skin, neck muscles or deeper structures, a neck lift may be more appropriate.

A facelift, too, pursues a different goal. It repositions descended tissue structures of the face, which can also change the contour along the lower jaw.

A clear jawline does not automatically result from more bone. What matters is which structure determines its contour.

Chin Implant or Genioplasty?

A chin implant and a genioplasty can both change the contour of the chin, but they follow different principles.

An implant supplements the existing bone structure and can be used in particular to enhance projection and contour.

In a genioplasty, by contrast, the patient's own chin bone is mobilised and repositioned. Depending on anatomy, this allows several dimensions of the chin to be changed.

Which method is more suitable cannot be answered in general terms.

Where mainly additional projection is needed, an implant can be an option. Where height, position, asymmetry or more complex proportions need to be changed, a bony repositioning can offer more possibilities. Where the goal is soft-tissue contouring rather than a bony change, a fat transfer to the face may be considered as a different type of alternative.

What matters is the existing anatomy and the desired treatment goal.

Chin and Nose in Profile

The nose and chin influence each other's perception.

A receded chin can make the nose appear more prominent in profile. Conversely, a pronounced chin projection can change the balance of the profile, even if the nose itself is harmoniously shaped.

For this reason, we always consider the nose in a chin correction, and the relationship to the chin in a rhinoplasty.

This does not mean that both regions should automatically be treated. Often, changing a single structure is enough to rebalance the relationship of the entire profile.

What matters is understanding, before treatment, which structure is actually responsible for the perceived imbalance.

Aesthetic Contour or Jaw Malposition?

Not every change to the chin and jaw is a purely aesthetic matter.

Where the upper and lower jaw differ significantly in position, this can affect not only facial proportions but also bite, chewing function and other functional aspects.

In such situations, isolated aesthetic contouring of the chin or lower jaw may not be sufficient.

A significant jaw malposition needs to be assessed orthodontically and by oral and maxillofacial surgery. Depending on the findings, orthognathic jaw surgery may be required.

These procedures pursue a different treatment goal than a purely aesthetic chin or jawline correction.

This distinction is important, so that the visible contour is not simply changed when the underlying cause lies in the position of the jaws relative to one another.

Feminine & Masculine Contours

The chin and jaw can contribute significantly to whether the lower face is perceived as softer, narrower, wider, or more defined.

As part of facial feminization & masculinization, changes to the chin and lower jaw can therefore form part of a more comprehensive treatment concept.

There is, however, no single feminine or masculine chin shape. Width, height, projection and angle must always be considered in relation to the existing facial structure.

The aim is not to reproduce stereotypical features, but to change, in a targeted way, the contours that are relevant to the individual treatment goal.

Surgical or Non-Surgical?

Not every change to the chin or jawline requires surgery.

With dermal fillers, smaller changes to projection or contour can be achieved in suitable situations. This can, for example, help assess how a stronger chin projection would affect the profile.

Non-surgical treatments, however, do not change the actual bone structure.

Where a more significant change to position, height, width or asymmetry is needed, surgical procedures can offer more possibilities.

The decision is therefore not based on which approach is generally better. What matters is which structure should be changed, and the desired extent of change.

The Profile Is a Relationship

A harmonious profile does not result from an ideal nose, an ideal chin, or a maximally defined jawline.

It results from the relationship between these structures.

The nose, lips, chin and neck form a connected silhouette. Changing one of these structures can also change how the others are perceived.

For this reason, we never consider a chin or jaw correction in isolation.

Sometimes a small change to chin projection is enough to make the entire profile appear more balanced. In other situations, the decisive change lies at a different anatomical point.

Not the strongest jawline or the most prominent chin is the goal. What matters is that the lower face belongs to the rest of the face.

Healing & Results

The healing phase depends on which structures are treated.

After bony procedures, swelling is normal at first and can be particularly pronounced around the chin and lower jaw. Temporary changes in sensation can also occur.

The early result therefore does not yet reflect the later contour.

As healing progresses, swelling decreases and the new proportions become clearer. After procedures on the bone, the tissue needs time to adapt to the changed structure.

How quickly the final result develops depends on the extent of the procedure and individual healing response.

The skin and soft tissue continue to change after a chin or jaw correction as part of the natural ageing process.

Consultation

A chin or jaw correction begins with the question of which structure actually determines the proportions of your lower face.

During your consultation at Clinic Selnau in Zürich, we assess the chin, lower jaw, jawline and neck, as well as their relationship to the nose, lips and the face as a whole.

We discuss which change concerns you, and whether its cause lies in the bone structure or the soft tissue above it.

On this basis, we assess whether a genioplasty, a chin implant, a change to the lower jaw contour, or another treatment approach makes sense.

Where there are indications of a relevant jaw malposition, this must be separately assessed orthodontically and by oral and maxillofacial surgery.

We discuss openly what result can realistically be expected, which surgical approach makes sense, how the healing phase unfolds, and what limitations and risks need to be considered.

The aim is not to change the chin or jaw as much as possible. It is to balance their shape and projection so that the profile and lower face work harmoniously together with the rest of the facial features.
