CBCT Scan for Jaw Fracture in Lahore
By Alnoor Diagnostic Centre | Shadman, Lahore
A Jaw Fracture Is a Serious Injury That Demands Accurate Diagnosis
Trauma to the face is among the most common causes of emergency presentations to hospitals and clinics across Lahore. Road traffic accidents, falls, sports injuries, workplace incidents, and physical altercations can all deliver sufficient force to fracture the jawbone — and when that happens, the quality of diagnosis in the hours and days that follow determines whether the patient recovers fully or is left with lasting functional and cosmetic consequences.
The jaw — comprising the mandible below and the maxilla above — is a complex, three-dimensional bony structure with a unique dual joint system, a full complement of teeth embedded within it, and important nerves and blood vessels running through it. When it fractures, the break can occur at multiple sites simultaneously, in patterns that a flat X-ray frequently misrepresents. Getting the diagnosis right requires three-dimensional imaging, and the CBCT scan is the investigation that provides it. At Alnoor Diagnostic Centre in Shadman, Lahore, we provide high-quality CBCT imaging that gives oral surgeons, maxillofacial specialists, and emergency clinicians across the city the precise information they need to manage jaw fractures safely and effectively.
Why Jaw Fractures Are More Complex Than They Appear
The mandible — the lower jaw — is a horseshoe-shaped bone that connects to the skull through the temporomandibular joints on both sides. Because of this curved, continuous structure, a significant impact rarely produces a fracture at only one point. The mandible commonly fractures at two or more sites simultaneously — a force applied to the chin, for example, frequently produces fractures at the symphysis in the front and at one or both condyles at the back, even though there is no direct impact at those sites.
The upper jaw — the maxilla — is part of the midface complex and fractures in characteristic patterns depending on the direction and force of impact. These midface fractures — classified as Le Fort fractures — involve varying combinations of the maxilla, the cheekbones, the nasal bones, and the orbital floor, and they frequently involve the sinuses as well.
Assessing all of these fracture patterns accurately — their exact location, their degree of displacement, the involvement of teeth and tooth roots, the proximity of nerve canals, and the integrity of the jaw joints — is simply not possible with conventional two-dimensional X-rays. The CBCT scan captures every detail in three dimensions, giving the treating team the complete picture they need before any treatment decision is made.
What the CBCT Scan Reveals in Jaw Fracture Assessment
Fracture location and pattern — The CBCT scan identifies every fracture line present throughout the entire jaw, both upper and lower, simultaneously. In the lower jaw, it clearly shows fractures at the symphysis, parasymphysis, body, angle, ramus, and condylar regions. In the upper jaw and midface, it identifies Le Fort fracture patterns, zygomatic fractures, and orbital floor involvement. Because multiple fractures frequently coexist after significant trauma, a comprehensive three-dimensional assessment prevents the common and serious error of identifying only the most obvious fracture while missing secondary fractures at other sites.
Degree of displacement and angulation — Not all fractures are equal in severity. A hairline fracture with no displacement may be managed conservatively. A significantly displaced fracture where the bone fragments have shifted out of alignment requires surgical reduction and fixation. The CBCT scan measures displacement and angulation with precision in all three dimensions, giving the surgeon the information needed to decide whether conservative management is sufficient or whether open reduction and internal fixation — using titanium plates and screws — is required.
Condylar fractures — The condyle is the rounded head of the lower jaw that sits within the temporomandibular joint. It is one of the most commonly fractured parts of the mandible, and condylar fractures are also among the most frequently missed on routine X-rays because overlapping bony structures obscure the joint on flat images. The CBCT scan shows both condyles simultaneously and in full three-dimensional detail, revealing fractures, displacement, and whether the condylar head has been displaced outside the joint socket entirely. This assessment is critical because inadequately treated condylar fractures lead to permanent jaw joint problems, limited mouth opening, facial asymmetry, and bite changes.
Involvement of teeth and tooth roots — Jaw fractures frequently pass through the tooth-bearing regions of the bone, running directly between or through tooth roots. Teeth in the fracture line may need to be retained to assist in fracture stabilisation or removed to prevent infection. The CBCT scan shows the precise relationship between the fracture line and every tooth root in the area, allowing the surgeon to make informed decisions about tooth management as part of the overall fracture treatment plan.
Inferior alveolar nerve canal — The inferior alveolar nerve runs through a canal inside the lower jaw and is responsible for sensation in the lower teeth, lip, and chin. Fractures of the lower jaw body and angle frequently involve this nerve canal. The CBCT scan maps the canal precisely and shows whether the fracture has disrupted it, informing the patient and surgeon about the risk and likely cause of post-traumatic numbness and guiding the surgical approach to minimise further nerve injury during repair.
Associated sinus involvement — Fractures of the upper jaw and midface frequently involve the maxillary sinuses. The CBCT scan shows sinus involvement clearly — including fluid or blood within the sinus, fractures of the sinus walls, and displacement of sinus anatomy — information that affects both the surgical approach and post-operative management.
How CBCT Guides the Surgical Repair Plan
Once the full fracture pattern is established through CBCT imaging, the oral surgeon or maxillofacial specialist can plan the repair procedure with precision. The three-dimensional images are used to determine the optimal fixation points for titanium plates and screws, the sequence in which multiple fractures should be reduced, and whether any teeth need to be managed before fixation begins.
In complex midface fractures involving multiple bones and joints, the CBCT data can be used to produce three-dimensional printed models of the patient’s fracture anatomy before surgery, allowing the surgical team to rehearse the repair procedure and pre-bend fixation plates to the exact shape needed. This technology saves significant operating time and improves the accuracy of fracture reduction, directly benefiting the patient’s functional and cosmetic outcome.
