“…Thus, each ratio received a value higher than one, if the measured left side was longer than the corresponding right side. A similar relationship ratio was reported earlier [15,39]. Further on, for the TrNa, Tr-SN, and TrPg ratios, each of their absolute differences from 1 was calculated.…”

“…Moreover, in our whole study cohort, facial symmetry improved from one to three years of age for the upper and lower jaw according to landmark-based measurements. Kreuz et al conducted a longitudinal study on facial asymmetry correction from 3D images using the same landmark-based measurements and reported that facial symmetry improved with helmet therapy treatment during their follow-up time of five months [39]. None of the subjects in our study cohort had a severe form of DP, and no helmet treatment was needed for anyone.…”

Deformational plagiocephaly (DP) is considered a risk factor for facial asymmetry. This cohort-based, prospective, follow-up study used three-dimensional (3D) stereophotogrammetry to assess the development of facial asymmetry in a normal birth cohort and to investigate the impact of DP on facial asymmetry for the age range of one to three years. The study sample consisted of 75 children: 35 girls (47%) and 40 (53%) boys recruited from Oulu University Hospital. A total of 23 (31%) subjects had a history of DP in infancy. 3D facial images were obtained at the mean (SD) age of 1.01 (0.04) year old at T1 and 3.02 (0.14) years old at T2. To determine facial asymmetry, both landmark-based and surface-based facial symmetry methods were used. As measured with the surface-based methods, upper facial symmetry improved from T1 to T2 (p < 0.05). As measured with the landmark-based methods, facial symmetry improved on the upper and lower jaw from T1 to T2 (p < 0.05). The asymmetric effect of DP on the upper parts of the face tends to correct spontaneously during growth. Results indicate that previous DP does not seem to transfer to facial or occlusal asymmetry at the age of three years old.

“…However, both plagiocephaly and brachycephaly have been shown to deform the skull base, affecting the position and orientation of the temporomandibular joints, and affect occlusal function. 2 - 7 Specifically, a brachycephalic deformation of the cranial vault results in a posterior tipping of the mid cranial fossa (central skull base) changing the angular orientation of the temporomandibular joints, and potentially resulting in Class III malocclusion (underbite). 8 - 13 Anterior displacement of the mandible may also affect the soft tissue of the upper airway leading to airway restrictions and obstructive sleep apnea.…”

Deformation of the cranium in infancy represents a spectrum of deformity, ranging from severe asymmetric yet proportional distortion of the skull in plagiocephaly, to nearly symmetric yet disproportional distortion in brachycephaly. As such, the condition is best described as deformational plagiocephaly-brachycephaly with isolated plagiocephaly and/or isolated brachycephaly being at either ends of the spectrum. Due to its symmetric appearance, deformational brachycephaly is often incorrectly dismissed as being less concerning, and it has sometimes erroneously been reported that brachycephaly cannot be treated successfully with a cranial orthosis. We prospectively report on 4205 infants with isolated deformational brachycephaly treated with a cranial orthosis from 2013 to 2017. These results demonstrate that the orthosis is successful in the treatment of deformational brachycephaly with an 81.4% improvement toward normal (95.0 to 89.4) in cephalic index. We furthermore demonstrate that entrance age influences treatment results, with younger infants demonstrating both improved outcomes and shorter treatment times.

“…The commonly used callipers and measurement tapes have a maximum precision of 1 mm. Visual tolerance for cranial and face asymmetry is considered approximately 2 mm [12]. The obtained precision confirms that a limited number of markers is enough for an accurate representation of the head, simplifying the obtainment of 3D models.…”

Cranial deformation is a problem that affects an important number of infants. It requires different treatments, varying from repositioning techniques to surgery depending on the leading cause. The evaluation of the deformation is usually carried out using simple but low-accuracy methodologies such as visual assessment and clinical measurements. Accurate methodologies such as radiological tests and combinations of cameras and scanner are available but they are invasive and/or costly. A patent-pending smartphone-based photogrammetric tool for the analysis of cranial deformation is presented. The methodology allows the generation of head three-dimensional (3D) models of infants automatically. It is non-invasive, low-cost and can be operated by users without any photogrammetric knowledge. The presented tool consists of a smartphone app, a coded cap that is fitted to the head of the infant and processing software that yields the 3D models. The data acquisition can be easily carried out during the routine clinical consultation. The patient is held by an adult while the application is used to obtain the data around the infant's head. The process is similar to a video recording, and the app guides the user during the process. The tool can tolerate the patient's movement so no immobilization or sedation is required. The whole data acquisition process can be completed in a couple of minutes. After the acquisition stage, the data is processed to obtain a 3D model of the patient's head. The accuracy and repeatability of the process have been tested under ideal conditions. The obtained accuracy was found to be better than 1 mm. The methodology has also been tested in real conditions obtaining models useful for the evaluation of different types of cranial deformation. The tool can be easily implemented in clinical routine. It requires minimum resources and provides a significant improvement of the techniques currently used for cranial deformation assessment.
