Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

Surgically assisted rapid palatal expansion (SARPE) effectively expands the adult maxilla. Computed tomography (CT) reveals non-uniform expansion, with greater width increase anteriorly and intermediately compared to the posterior maxilla.

Background:

Transverse maxillary deficiency is commonly treated with surgically assisted rapid palatal expansion (SARPE) in adults.
Objective evaluation of SARPE's skeletal effects using computed tomography (CT) remains underexplored.
Limited defined landmarks exist for assessing maxillary expansion post-SARPE.

Purpose of the Study:

To define parameters for assessing skeletal changes following SARPE.
To utilize CT imaging to evaluate these defined parameters.
To analyze the pattern and uniformity of transverse maxillary expansion after SARPE.

Main Methods:

Fifteen adult patients underwent SARPE (modified Le Fort I osteotomy without pterygomaxillary separation and sagittal palatal osteotomy).
Axial and coronal CT views were used to measure linear and angular changes in anterior, intermediate, and posterior maxilla.
Maxillary cross-sectional area was calculated to assess overall expansion.

Main Results:

The study confirmed the reliability of CT for evaluating SARPE outcomes.
Significant overall transverse expansion of the maxilla was achieved.
Expansion patterns varied, with greater increases in maxillary width observed in the anterior and intermediate regions compared to the posterior.

Conclusions:

SARPE is an effective procedure for treating transverse maxillary deficiency.
CT imaging is crucial for accurate postoperative assessment of SARPE.
Transverse expansion achieved with SARPE (without pterygoid plate separation) is not uniform across all maxillary regions.
