“…CLP can impair breathing, swallowing, and mastication (Bugaighis et al, ). Facial traits typically associated with CLP include a clefted lip and palate, midfacial hypoplasia, a deviated anterior nasal spine, a distorted nasal septum, reduced nasal chamber width, an inferiorly positioned nasal border, and asymmetry of the maxilla, mandible, and nasolabial regions of the face (Harvold, ; Molsted and Dahl, ; Ras et al, ; Ras et al, ; Son, ; Kolbenstvedt et al, ; Suri et al, ; Jena et al, ; Agarwal et al, ; Bell et al, ; Bugaighis et al, ; Choi et al, ; Freeman et al, ; Hasanzadeh et al, ). Surgical repair of the primary cutaneous upper lip is usually carried out around 2–3 months of age, whereas surgical repair of the hard palate is generally carried out around 6–12 months of age (Kolbenstvedt et al, ; Marazita, ).…”

“…Individuals with CLP commonly have septal deviation due to (1) unilateral attachment of the orbicularis oris to the anterior caudal septum on the non‐affected side, (2) unilateral attachment of the vomer secondary to clefting of the hard palate, (3) lateral deviation of the lower and middle vault secondary to unopposed action of the zygomaticus major and minor on the alar base, and (4) compounded scoliosis of the septum, lower and middle vault secondary to deviation of the greater and lesser segments of the alveolus (Hall and Precious, ). Surgically repaired faces often exhibit iatrogenic scarring and facial asymmetries that contribute to stigmata (Seidenstricker‐Kink et al, ; Choi et al, ; Freeman et al, ).…”

Nasal airway and septal variation in unilateral and bilateral cleft lip and palate

Cleft lip and palate (CLP) affects the dentoalveolar and nasolabial facial regions. Internal and external nasal dysmorphology may persist in individuals born with CLP despite surgical interventions. 7-18 year old individuals born with unilateral and bilateral CLP (n 5 50) were retrospectively assessed using cone beam computed tomography. Anterior, middle, and posterior nasal airway volumes were measured on each facial side. Septal deviation was measured at the anterior and posterior nasal spine, and the midpoint between these two locations. Data were evaluated using principal components analysis (PCA), multivariate analysis of variance (MAN-OVA), and post-hoc ANOVA tests. PCA results show partial separation in high dimensional space along PC1 (48.5% variance) based on age groups and partial separation along PC2 (29.8% variance) based on CLP type and septal deviation patterns. MANOVA results indicate that age (P 5 0.007) and CLP type (P 0.001) significantly affect nasal airway volume and septal deviation. ANOVA results indicate that anterior nasal volume is significantly affected by age (P 0.001), whereas septal deviation patterns are significantly affected by CLP type (P 0.001). Age and CLP type affect nasal airway volume and septal deviation patterns. Nasal airway volumes tend to be reduced on the clefted sides of the face relative to non-clefted sides of the face. Nasal airway volumes tend to strongly increase with age, whereas septal deviation values tend to increase only slightly with age. These results suggest that functional nasal breathing may be impaired in individuals born with the unilateral and bilateral CLP deformity. Clin. Anat. 00:000-000,

“…The presence of an orofacial cleft causes physical and functional disturbances to the craniofacial complex that affect individuals both physically and psychologically (6,7) . Multiple anatomical variations are seen in CLP patients as midfacial hypoplasia, hypoplastic maxillary sinus, deviated nasal septum and various dental anomalies (8)(9)(10) .…”

Objective: The purpose of this study was to investigate maxillofacial morphology using CBCT with the ultimate goal of finding whether differences existed in a two suggested subtypes of nonsyndromic bilateral cleft lip and palate (BCLP) patients.Design: This retrospective study included CBCT data of 22 BCLP patients with mean age of 9.6 years. The patients were divided initially according to premaxillary characteristics into two groups and this classification was further confirmed by measurement of sella-nasion-point A angle (SNA), Group (P): This represent BCLP characterized by well-developed (P) prominent pre-maxilla and SNA >80±2, Group(R): This represent BCLP characterized by ill-developed (R) rudimentary pre-maxilla and SNA < 80±2. The relation between maxilla and mandible measured by point A-nasion-B point angle (ANB), angle of septal deviation (ASD) and anterior upper facial height (AUFH) were assessed using On-demand 3D software and was compared among the two groups.Results: Patients within group P showed significantly higher ANB (P value ≤ 0.001). Patients within group R showed significantly higher ASD angle (P value ≤ 0.05), while AUFH showed insignificant difference between the two groups (P value ≥ 0.05). Conclusions:Maxillofacial morphology measurements assessed in this study support that difference exist between the two investigated subtypes of non-syndromic BCLP.

“…Photo documentation of the face is of fundamental importance for follow-up, communication with patients or parents, illustrative purposes in lectures or medico-legal requirements, and nowadays in surgical planning. Two-dimensional (2D) images have been and are the gold standard for this purpose and can be used to reliably assess phenotypic severity of craniofacial anomalies as stated earlier [ 1 – 5 ]. Considering the drawbacks of conventional 2D photography in picturing three-dimensional (3D) structures and the patient’s exposure to radiation in traditional 3D surface recognition as cephalometry, cone beam scan or computed tomography, non-invasive 3D surface imaging has become more popular in the last decade [ 6 ].…”

The possibilities of a portable low-budget three-dimensional stereophotogrammetry system in neonates: a prospective growth analysis and analysis of accuracy

BackgroundWith the technical development, portable three-dimensional (3D) photogrammetry systems are becoming more en vogue because of cost-effectiveness and comparable accuracy to common stationary 3D systems. The purpose of the study was to evaluate the feasibility and accuracy of a low-budget portable system for 3D image acquisition with special regard to the gracile nasal region in neonates. Furthermore, the study aimed to establish a 3D data set of the first 180 days post partum.MethodsThirty-three healthy, full-term newborn were enrolled and 3D photographs were prospectively taken monthly with a portable low-budget 3D stereophotogrammetry system (FUEL3D® SCANIFY®) for six months. In the third month, age-matched and corresponding 3D models were acquired by taking an impression of the perinasal area. The resulting plaster models were scanned (3Shape D700, 3Shape® A/S, Denmark). Three examiners analyzed independently 21 defined landmarks of the generated Standard Tessellation Language files with regard to accuracy by using 3dMDvultus™ software. A semi-automatic 3D best-fit analysis of 3D photo and plaster models were performed by using Geomagic® and the Root Mean Squared (RMS) errors were calculated.ResultsStatistically significant changes of midfacial distances and angles with a focus on nasal growth during the first 180 days postpartum could be specified in absolute and relative dimensions. Best-fit analysis in the third month revealed a RMS error of 0.72 ± 0.22 mm with a mean standard deviation of 0.71 ± 0.21 mm.ConclusionsThe analyzed portable 3D stereophotogrammetry system is a feasible methodology with good accuracy, even in newborn. A description of the growth as well as the establishment of a 3D data set was performed. Its implementation for basic documentation for example in cleft patients is possible and might reduce the need for impressions and facilitate the communications with parents and the interdisciplinary team.
