This comprehensive clinical study focuses on evaluating the therapeutic impact of
orthodontic maxillary expansion treatment on sleep disorder assessments in children, as
reported by their parents or guardians using the Pediatric Sleep Questionnaire (PSQ).
Maxillary transverse constriction is a developmental disorder that can adversely affect
the orofacial region, potentially influencing breathing patterns during sleep. The
primary objective is to investigate whether orthodontic intervention to widen the upper
jaw can lead to favorable developmental outcomes in the orofacial region and potentially
alleviate sleep-related breathing disorders.
The study will involve 20 patients diagnosed with transverse maxillary constriction,
identified through 3D scans of their face and dentition, compared against a control group
of individuals without such constriction. Before and one year after treatment,
participants will undergo 3D scanning of their facial structure and dentition,
complemented by the completion of PSQ questionnaires by their parents or guardians. The
study's hypotheses propose that following treatment, there will be notable changes in
the mid-facial region evident from 3D facial scans, an increase in palate volume as
indicated by dental scans, and a moderate improvement in reported sleep disorder symptoms
based on parental observations.
The research methodology incorporates non-invasive 3D facial scanning technology, a
methodological advancement that allows for precise assessment of facial changes
pre-treatment and post-treatment. This approach contrasts with traditional 2D imaging,
offering more detailed and accurate data on structural alterations. The study also
highlights the utility of PSQ as a validated tool for evaluating sleep disorders in
children, avoiding the need for expensive polysomnography.
By utilizing advanced imaging techniques and validated questionnaires, researchers seek
to objectively measure treatment outcomes and correlate them with improvements in sleep
quality and respiratory function. The study will utilize specialized equipment such as
the Bellus 3D facial scanner and the Audaxceph software.
Ultimately, this study aims to enhance our understanding of the relationship between
maxillary expansion therapy and sleep disorder improvement in children, potentially
paving the way for optimized treatment protocols and improved patient outcomes sleep
related breathing problems.
