Bottom Line: Primary publications on facial growth and treatment outcomes in children younger than six years of age were included.Independent data extraction by two observers.In general the measurement error was below 1 mm and 1° and correlation coefficients range from 0.65 to 1.0.

ABSTRACT

Context: Technological advancements have led craniofacial researchers and clinicians into the era of three-dimensional digital imaging for quantitative evaluation of craniofacial growth and treatment outcomes.

Objective: To give an overview of soft-tissue based methods for quantitative longitudinal assessment of facial dimensions in children until six years of age and to assess the reliability of these methods in studies with good methodological quality.

Data source: PubMed, EMBASE, Cochrane Library, Web of Science, Scopus and CINAHL were searched. A hand search was performed to check for additional relevant studies.

Study selection: Primary publications on facial growth and treatment outcomes in children younger than six years of age were included.

Data extraction: Independent data extraction by two observers. A quality assessment instrument was used to determine the methodological quality. Methods, used in studies with good methodological quality, were assessed for reliability expressed as the magnitude of the measurement error and the correlation coefficient between repeated measurements.

Results: In total, 47 studies were included describing 4 methods: 2D x-ray cephalometry; 2D photography; anthropometry; 3D imaging techniques (surface laser scanning, stereophotogrammetry and cone beam computed tomography). In general the measurement error was below 1 mm and 1° and correlation coefficients range from 0.65 to 1.0.

Conclusion: Various methods have shown to be reliable. However, at present stereophotogrammetry seems to be the best 3D method for quantitative longitudinal assessment of facial dimensions in children until six years of age due to its millisecond fast image capture, archival capabilities, high resolution and no exposure to ionizing radiation.

pone-0041898-g001: PRISMA flow diagram of study selection process.

Mentions: The search of PubMed, EMBASE, Cochrane Library, Web of Science, Scopus and CINAHL provided a total of 6380 citations and the hand search provided 191 citations. After adjusting for duplicates 5077 remained for screening of title and abstract. Of these, 4022 studies were discarded because these did not meet the eligibility criteria. A total of 1055 studies remained for full text assessment of eligibility. Of these, 859 studies were excluded with reasons. Of these excluded studies, 192 were discarded because the full text publication could not be retrieved. The last step in the inclusion process divided the studies into facial evaluation (n = 47) and studies on cranial evaluation (n = 149). A total of 196 studies was identified meeting the inclusion criteria; 175 studies originated from the electronic databases; the remaining 21 studies originated from the additional handsearch of the references of the included studies. Figure 1 shows the PRISMA flow diagram and figure S1 shows the PRISMA checklist [30]. This study is restricted to studies on facial evaluation of growth and treatment outcome in children.
