Computed tomography, maxillofacial area; without contrast material
CPT4 code
Name of the Procedure:
Computed Tomography (CT) of the Maxillofacial Area Without Contrast Material
Summary
A CT scan of the maxillofacial area uses X-rays to create detailed images of the facial bones and tissues. This non-invasive procedure helps doctors diagnose and evaluate conditions affecting the face, sinuses, and jaw without using contrast material.
Purpose
The primary goal of this CT scan is to diagnose and assess conditions such as facial fractures, infections, tumors, and sinus issues. It provides clear, detailed images to aid in treatment planning and monitoring.
Indications
- Persistent facial pain or swelling
- Suspected facial bone fractures
- Chronic sinusitis unresponsive to treatment
- Pre-operative planning for maxillofacial surgery
- Evaluation of facial or dental abnormalities
Preparation
- No specific preparation is needed.
- Patients should inform their doctor of any metal implants or devices in the head/neck area.
- Removal of metal objects like glasses or jewelry before the scan.
Procedure Description
- The patient lies on a motorized table that slides into the CT scanner.
- The patient may need to hold their head still and follow breathing instructions.
- The scanner rotates around the head, capturing multiple X-ray images.
- A computer processes these images to create detailed cross-sectional views.
- No contrast material is injected or ingested.
Duration
The scan typically takes about 10-20 minutes.
Setting
This procedure is performed in the radiology department of a hospital or outpatient imaging center.
Personnel
- Radiologic technologists operate the CT scanner.
- A radiologist interprets the images.
- Support staff may assist as necessary.
Risks and Complications
- Exposure to a low dose of radiation.
- Rare risk of allergic reaction if contrast used in the future.
Benefits
- Provides precise, high-resolution images of facial structures.
- Non-invasive and quick.
- Helps in accurate diagnosis and effective treatment planning.
Recovery
- No recovery time needed.
- Patients can resume normal activities immediately after the scan.
- Follow-up appointments if further diagnostic or treatment plans are necessary.
Alternatives
- X-rays: less detailed but involve less radiation.
- MRI: provides detailed images of soft tissues but takes longer and is more expensive.
- Ultrasound: used for soft-tissue evaluation but less effective for bone imaging.
Patient Experience
- The procedure is usually painless.
- Some discomfort may arise from lying still.
- Noise from the scanner but typically not loud.
- Anxiety might be managed with relaxation techniques or mild sedatives if necessary.
