RESUMEN
With increasing interest in 3D photogrammetry, diverse methods have been developed for craniofacial shape analysis in craniosynostosis patients. This review provides an overview of these methods and offers recommendations for future studies. A systematic literature search was used to identify publications on 3D photogrammetry analyses in craniosynostosis patients until August 2023. Inclusion criteria were original research reporting on 3D photogrammetry analyses in patients with craniosynostosis and written in English. Sixty-three publications that had reproducible methods for measuring cranial, forehead, or facial shape were included in the systematic review. Cranial shape changes were commonly assessed using heat maps and curvature analyses. Publications assessing the forehead utilized volumetric measurements, angles, ratios, and mirroring techniques. Mirroring techniques were frequently used to determine facial asymmetry. Although 3D photogrammetry shows promise, methods vary widely between standardized and less conventional measurements. A standardized protocol for the selection and documentation of landmarks, planes, and measurements across the cranium, forehead, and face is essential for consistent clinical and research applications.
RESUMEN
This review provides a comprehensive overview of the literature on velopharyngeal insufficiency, associated anomalies, and speech/language impairment in patients with craniofacial microsomia (CFM). A systematic search of the literature was conducted to identify records on VPI and speech impairment in CFM from their inception until September 2022 within the databases Embase, PubMed, MEDLINE, Ovid, CINAHL EBSCO, Web of Science, Cochrane, and Google Scholar. Seventeen articles were included, analysing 1,253 patients. Velopharyngeal insufficiency results in hypernasality can lead to speech impairment. The reported prevalence of both velopharyngeal insufficiency and hypernasality ranged between 12.5% and 55%, while the reported prevalence of speech impairment in patients with CFM varied between 35.4% and 74%. Language problems were reported in 37% to 50% of patients. Speech therapy was documented in 45.5% to 59.6% of patients, while surgical treatment for velopharyngeal insufficiency consisted of pharyngeal flap surgery or pharyngoplasty and was reported in 31.6% to 100%. Cleft lip and/or palate was reported in 10% to 100% of patients with CFM; these patients were found to have worse speech results than those without cleft lip and/or palate. No consensus was found on patient characteristics associated with an increased risk of velopharyngeal insufficiency and speech/language impairment. Although velopharyngeal insufficiency is a less commonly reported characteristic of CFM than other malformations, it can cause speech impairment, which may contribute to delayed language development in patients with CFM. Therefore, timely recognition and treatment of speech impairment is essential.
