Osteotomies in Rhinoplasty — Why We Break the Nose
This page is intended as general information for patients considering rhinoplasty. It does not constitute medical advice. All cosmetic surgery involves risks and individual results vary.
One of the most common surprises patients encounter during rhinoplasty consultation is learning that their surgery involves controlled fractures of the nasal bones. The word “osteotomy” — derived from the Greek for bone cutting — describes exactly this: a precise, planned division of the nasal bones to allow them to be repositioned. It is not a complication or an accident. It is a deliberate and essential surgical step in a significant proportion of rhinoplasty cases.
Understanding why osteotomies are needed, when they are performed, and what to expect from them removes a significant source of patient anxiety and is an important part of genuinely informed consent.
The Nasal Bony Vault — Anatomy
The upper third of the nose is formed by two paired nasal bones — flat plates of bone that originate from the frontal process of the maxilla at the sides and meet at the midline above. They form the nasal bridge and the upper lateral walls of the nose. Below them, the upper lateral cartilages attach and continue the nasal sidewall down to the tip.
The nasal bones are not free-floating — they are firmly attached to the maxilla at their lateral edges and to each other at the midline. This means that repositioning them requires controlled fracture. You cannot narrow the bony base, correct a deviation of the upper nose, or close an open roof simply by pushing or suturing — the bone must be cut and moved.
When Are Osteotomies Needed?
Types of Osteotomy
Lateral osteotomies
The most commonly performed osteotomy in rhinoplasty. A cut is made along the lateral aspect of each nasal bone, from low on the pyriform aperture (the bony opening of the nose) upward toward the inner canthus of the eye. This frees the nasal bone from its lateral attachment to the maxilla and allows it to be moved medially. Lateral osteotomies may be performed percutaneously — through a small puncture in the skin — or endonasally through the nostril.
Medial osteotomies
A cut along the midline of the nasal dorsum, freeing the nasal bones at their medial (central) attachment. Required in cases of significant deviation or when the nasal bones need to be mobilised independently. Often combined with lateral osteotomies to allow complete mobilisation of each nasal bone segment.
Transverse osteotomies
A horizontal cut across the nasal bone, typically at its superior end near the nasofrontal angle. Used in preservation rhinoplasty push-down and let-down techniques to allow the bony vault to move inferiorly, and in cases where the nasal bones need to be shortened.
Intermediate osteotomies
An additional cut between the lateral and medial osteotomies, used to correct significant convexity or irregularity of the nasal bone and to allow a precise, controlled movement of a specific bony segment. Less commonly required but important in certain revision and correction cases.
What to Expect — Bruising, Swelling, and Recovery
Osteotomies produce more post-operative bruising and swelling than rhinoplasty without bone work — this is expected and normal. The bruising — which extends under the eyes in most patients — typically peaks at 48–72 hours and resolves over one to two weeks. Swelling of the bony dorsum takes longer to resolve than soft tissue swelling and may give the nose a slightly wide appearance for the first several weeks.
The nasal bones are held in their new position by the overlying periosteum and soft tissues during healing. A rigid external splint is worn for the first week to protect the bones and support their position while initial healing occurs. Patients are advised to avoid any direct trauma to the nose for at least six weeks — this means contact sport, impact activities, and anything that could displace the healing bones must be avoided.
The bony dorsum should be considered fragile until approximately six weeks post-operatively. After that, the bones are sufficiently healed to tolerate normal activity. The final position of the nasal bones becomes apparent once swelling has resolved — typically by two to three months — though subtle changes continue for up to a year.
Dr Roth’s Clinical Perspective
The phrase “we need to break your nose” — which is how patients sometimes describe what they have been told — is understandably alarming. The reality is that osteotomies are controlled, precise cuts made with purpose-designed instruments under direct visualisation. They are not blunt trauma. The nasal bone is cut where it needs to be cut, moved to where it needs to go, and held there by the soft tissue envelope while it heals. The process is deliberate and the result, when performed correctly, is stable and lasting.
What patients find most useful to understand is why the osteotomies are necessary for their specific case. For a patient having a hump removed, the open roof explanation is immediately logical — of course you need to close the gap. For a patient having preservation rhinoplasty, the need for osteotomies is less intuitive — the whole point was supposed to be avoiding the open roof — but once you understand that the push-down technique requires the bone to physically move downward and that it cannot move unless it is freed from its attachments, the logic is clear.
I spend time on this explanation at consultation because a patient who understands why the bone work is needed arrives at surgery with realistic expectations about bruising, recovery, and the appearance of the nose in the first few weeks. That understanding makes the recovery significantly less distressing.
