In short. The practical fortnight and the months of uneven swelling that follow. What is limited, for how long, and what nobody warns you about.
Key points
- The practical preparation that makes the most difference is having soft food available that you actually want to eat, in portions you can manage without chewing.
- Patients who arrange this before the operation describe the first week very differently from those who improvise.
- The same applies to the compression band: knowing how it is worn and how it is cleaned before the first night is easier than working it out while swollen.
The recovery from this operation is dominated by swelling rather than by pain, and the swelling lasts far longer than most patients expect. Understanding the shape of it in advance is what stops the first three months being read as a failed result.
The first week
Swelling is at its worst from the start, and the face feels tight and heavy. A compression band is worn, talking is effortful, and swelling and bruising peak around the third day rather than immediately. The jaw aches rather than hurts at rest. The diet is soft, with no chewing on hard food, and the first days are mostly spent resting with the head elevated. Most patients describe this week as uncomfortable rather than painful.
Prepare the food before the operation
The practical preparation that makes the most difference is having soft food available that you actually want to eat, in portions you can manage without chewing. Patients who arrange this before the operation describe the first week very differently from those who improvise. The same applies to the compression band: knowing how it is worn and how it is cleaned before the first night is easier than working it out while swollen.
Weeks two to six
Bruising has usually faded by the second week and most people can be in public, though the swelling still hides the contour and remains uneven on the two sides. The lower face softens week by week. Numbness of the chin and the lower lip is expected in this period and is watched rather than treated, because it is the nerve recovering rather than a problem to be corrected. Chewing remains the activity that provokes the ache, and hard food stays off the list.
Two months and beyond
The first honest look at the width and the border comes around two to three months, with residual swelling and returning sensation both still changing the picture. At six months most of the swelling has gone and the contour is close to final, and numbness still present at that point is less likely to resolve fully. Final judgement belongs at around a year, which is also the earliest point at which a genuine asymmetry or an over-reduction can be assessed properly.
Reasons to contact the team during recovery
- Swelling that is increasing rather than settling after the first week, or that is much greater on one side.
- A wound that is opening, or discharge or spreading redness around an incision.
- A weakness of the lower lip that is worsening rather than improving, or difficulty breathing or swallowing.
None of this is a reason to be anxious about the operation. It is the honest shape of a recovery in which the result is hidden for months, and knowing that in advance is what allows the waiting to be read as healing rather than as disappointment.
Frequently asked questions
When can I eat normally again?
A soft diet and no chewing on hard food for the first period, which your team will specify, and a gradual return rather than a switch. The jaw aches rather than hurts at rest in the first days, and chewing is what provokes it. Most people are eating a fairly normal diet within a few weeks, and the ache on chewing is the last thing to settle.
Will my speech be affected?
In the first days talking is effortful, partly from swelling and partly from the ache. It improves quickly, and a temporary change in how clearly some sounds come out is common while the swelling is at its worst. A persistent change in speech is not expected, and it is worth raising at a review rather than waiting it out.
How long is the swelling visible?
At two weeks most people are comfortable in public and the swelling still hides the contour. At three months most of it has gone. At six months the contour is close to final. It resolves unevenly on the two sides, so the face looks uneven before it looks even, which is the part patients are least prepared for.
Risks & Limitations
- Removing bone is easier than restoring it. Over-reduction is difficult and sometimes impossible to correct, so the amount removed is decided from imaging and treated as fixed.
- The marginal mandibular nerve, which moves the lower lip, runs through the operative field. Weakness after surgery is usually temporary and usually resolves over weeks to months; a lasting weakness is uncommon but possible.
- Swelling hides the result for months. The face reads unevenly at two weeks, is not close to final until around six months, and is judged honestly at around a year.
- Numbness of the chin and the lower lip is expected, is watched rather than treated in the early weeks, and may not return fully in some areas.
- The two sides of a jaw are rarely identical, and reducing both by the same amount can make a pre-existing difference more visible.
- The operation changes width and the border between the jaw angle and the chin. It does not lengthen the face, correct a bite, or change the soft tissue over the new contour.
When to Seek Care
- Swelling that is increasing rather than settling after the first week, or that is much greater on one side — contact the team.
- A wound that is opening, or discharge, spreading redness or warmth around an incision.
- A weakness of the lower lip that is worsening rather than improving, or difficulty breathing or swallowing &mdash — seek emergency care at once.
- Fever, or feeling generally very unwell with a wound or a swollen area.
- Calf pain, swelling or tenderness in one leg, or shortness of breath or chest pain &mdash — seek emergency care at once.
