Infants presenting with cranial deformities characterized by abnormal cranial shape or asymmetry during early infancy, including deformities affecting cranial symmetry, cranial proportions, and head contour. Participants are infants within the period of rapid cranial growth, for whom cranial remolding orthosis treatment is clinically indicated. The cohort includes infants of both sexes, with varying degrees of cranial deformity severity, and without neurological or syndromic conditions that could affect cranial growth. All infants are otherwise medically stable and suitable for conservative orthotic management.

The intervention consisted of treatment with a custom-fabricated cranial remolding orthosis (CRO). Each orthosis was individually designed based on the infant's cranial shape using three-dimensional cranial scanning and computer-aided modeling. A mold was produced using CNC technology, and a thermoplastic material was formed over the mold to create the final orthosis. The fabricated CRO was delivered to the clinic within a few days and fitted to the infant.

During the initial fitting, the orthosis was clinically inspected for proper fit and for any signs of skin redness, irritation, or pressure-related issues. Necessary adjustments were made, and parents were provided with detailed instructions regarding orthosis use and care. Infants were subsequently scheduled for regular clinical follow-up, and only custom-fabricated cranial remolding orthoses were included in the study.

The primary outcome measure is the change in cranial morphology assessed by standardized anthropometric measurements obtained before and after cranial remolding orthosis (CRO) treatment. Cranial measurements include anterior-posterior and medio-lateral dimensions, right and left frontal measurements, and head circumference. Changes in these measurements are used to quantify objective cranial morphological improvement over the course of treatment.

Parental expectations regarding cranial remolding orthosis treatment are assessed before initiation of treatment using the Treatment Expectation Questionnaire. This measure evaluates parents' expectations related to treatment outcomes, process, and perceived benefits prior to intervention.The Treatment Expectation Questionnaire is a generic, multidimensional patient-reported outcome measure consisting of 15 items assessing expectations across multiple domains of treatment. Each item is rated on a numerical scale from 0 (no expected change) to 10 (maximum expected change), yielding a total score range of 0 to 150, with higher scores indicating greater treatment expectations.

Parental satisfaction with cranial remolding orthosis treatment is assessed after completion of the treatment period using the Quebec User Evaluation of Satisfaction with Assistive Technology. This measure evaluates satisfaction with the cranial remolding orthosis in terms of device-related characteristics and overall satisfaction with the assistive technology.
