The usefulness of cone beam computed tomography according to age in cleft lip and palate

Abstract

The current study aimed to evaluate the usefulness of cone beam computed tomography (CBCT) examination in cleft children and adolescents, the age of the first CBCT exposure, and the criteria that justified the first CBCT exposure. A number of 229 non-syndromic cleft subjects aged between 0–22 years receiving treatment in the same specialized surgical center in orofacial cleft treatment were studied. A cleft group of 64 cleft lip and palate (CLP) children with at least one CBCT exposure was identified based on CBCT records. Parameters related to diagnosis and treatment planning in cleft deformity were considered dental anomalies and bone morphology changes. The examiners assessed whether the treatment option was necessary, not necessary, or could not be evaluated at the age of CBCT exposure. A number of thirty-nine unilateral clefts and fifteen bilateral clefts were identified. Posterior palatal cleft was present in six children (mean age: 15.03±5.55 years; male/female ratio: 1/0.8). Alveolar bone morphology changes were found in 90.58% of cases; jaw relationship changes in 71.82%; nasal fossa morphology changes in 74.99%; airway obstruction in 49.98% and maxillary asymmetry in 87.48%. Orthodontic planning was necessary for 85.93% of CLP patients, and orthognathic surgery in 39.05%. The usefulness of CBCT in patients with CLP varied with age, with reduced value for the evaluation of impaction and root resorption under the age of ten.

Métodos de obtención de modelos de trabajo o estudio de niños con labio y paladar fissurado: Una revisión sistemática

“…La tomografía computarizada utiliza radiación ionizante que puede dañar el ADN, los niños suelen ser los más vulnerables a la carcinogénesis por lo que se debe evaluar los costos beneficios antes de aplicar este procedimiento, (Thurzo et al, 2022) así también, no es recomendado a menores de 6 años debido a que no existe un protocolo adecuado para el tratamiento de infantes. (Dinu et al, 2022) Es utilizado para evaluar la asimetría del maxilar inferior, la cara, el paladar, el desarrollo de la dentición mixta, la morfología de las fosas nasales y la posición del tabique o los cornetes para diagnosticar posibles complicaciones respiratorias.…”

“…Compared to conventional CT scans, CBCT offers several advantages, including lower cost, improved spatial resolution, better bone definition, and crucially, reduced radiation exposure [ 6 ]. This reduction in radiation exposure is particularly significant for young patients, who are more susceptible to the adverse effects of ionizing radiation and often require multiple imaging sessions in infancy and childhood [ 7 ].…”
