Patients with unilateral cleft lip display characteristic nasal changes that are independent of the degree of deformity. Defenders of the intrinsic theory consider these deformities to be due to embryogenic alterations of the alar nasal cartilages. Those that propose the extrinsic theory defend the thesis that the deformity is due to disorganization of the perioral muscles deformed by the cleft. The purpose of this study is to contribute histological evidence to help clarify the issue. PATIENTS AND METHODS: Specimens of the lateral portion of both the healthy and the cleft side of the alar cartilages were obtained from 18 patients. These uniformly cut specimens were stained by hematoxylin and eosin. Samples from 2 patients were excluded due to imperfections. The same pathologist examined all the slides. He was unaware of the origins of the specimens; he counted the number of chondrocytes and quantified the cartilage matrixes. RESULTS: All data was analyzed statistically, and no significant statistical differences were apparent, either in the number of chondrocytes or the cartilage matrix between the healthy side and the cleft side. DISCUSSION: These results apparently support the group that defend the extrinsic theory; nevertheless, the doubt about the composition of the cartilage matrix remains, not only concerning the glycosaminoglycans that compose them, but also regarding elastin and collagen and its linkages that can cause different degrees of collagen consistency.

Objective: To quantify 3-dimensional (3D) nasal changes in infants with unilateral cleft lip with or without cleft palate (UCL±P) treated by nasoalveolar molding (NAM) and cheilorhinoplasty and compare to noncleft controls. Design: Retrospective case series of infants treated with NAM and primary cheilorhinoplasty between September, 2012 and July, 2016. Infants were included if they had digital stereophotogrammetric records at initial presentation (T1), completion of NAM (T2), and following primary cheilorhinoplasty (T3). Images were oriented in 3dMD Vultus software, and 16 nasolabial points identified. Patients: Twenty consecutively treated infants with UCL±P. Interventions: Nasoalveolar molding and primary cheilorhinoplasty. Main Outcome Measures: Anthropometric measures of nasal symmetry and morphology were compared in the treatment group between time points using paired Student t tests. Postsurgical nasal morphology was compared to noncleft controls. Results: Nasal tip protrusion increased, and at T3 was 2.64 mm greater than noncleft controls. Nasal base width decreased on the cleft side by 4.01 mm after NAM and by 6.73 mm after cheilorhinoplasty. Columellar length of the noncleft to cleft side decreased from 2:1 to 1:1 following NAM. Significant improvements in subnasale, columella, and nasal tip deviations from midsagittal plane were observed. Treatment improved symmetry of the alar morphology angle and the nasal base–columella angle between cleft and noncleft sides. Conclusions: Three-dimensional analysis of UCL±P patients demonstrated significant improvements in nasal projection, columella length, nasal symmetry, and nasal width. Compared to noncleft controls, nasal form was generally corrected, with overcorrection of nasal tip projection, columella angle, and outer nasal widths.

Introduction: Cleft Lip and Palate (CLAP) is one of the most frequent craniofacial anomalies. The management of patients with CLAP requires several repair procedures for the soft palate, the primary and secondary bony palate, the alveolar ridge, the lips and the nose. These patients often present with a maxillary transverse deficit responsible for maxillary endognathy which must be corrected for a harmonious development of the maxillomandibular complex. The objective of our work was to evaluate the efficacy of slow, rapid and surgical maxillary expansion in patients with sequelae of CLAP following a systematic review protocol. Materials and methods: Four databases were searched: PubMed / MEDLINE, ScienceDirect, Cochrane Library and EBSCOhost, using the keywords present in the MeSH according to the equation [Maxillary expansion] AND [Cleft lip and palate]. The selection of articles included all studies published since January 2010 and for which the full text is available, such as meta-analyzes, randomized and non-randomized controlled clinical trials, case-control studies and prospective and retrospective studies. Results: Among 1107 references only 8 studies met our inclusion criteria. Following analysis of these, we concluded that there is no significant difference between rapid maxillary expansion and slow maxillary expansion in patients with unilateral CLAP, the expansion observed on the side of the cleft is larger than that seen on the healthy side. Surgically assisted expansion is much more reserved for subjects at the end of growth, having unilateral or bilateral CLAP and presenting anterior or posterior lateral crossbones. The results of our systematic review also showed that maxillary expansion in patients with CLAP results in substantial dentoalveolar compensation. Conclusion: The efficacy of maxillary expansion in patients with sequelae of CLAP is real and alone in some cases allows the restoration of a normal transverse dimension; sometimes in combination with maxillary protraction to correct the anteroposterior deficit.

(1) Background: Despite cleft lips and palates belonging to the most common orofacial congenital anomalies, their morphopathogenesis is not yet fully understood. The study aimed to determine the distribution and relation of cytokines interferon-γ (IFN-γ), tumor necrosis factor-alpha (TNF-α), interleukin (IL)-2, IL-7, IL-12, and IL-13 in the cleft affected mucosa of the lip. (2) Materials and Methods: Twenty cleft lip (CL) mucosal samples and seven control tissues of oral cavity mucosa were included in the study. Specimen were obtained during reconstruction surgeries and processed by hematoxylin and eosin staining and immunohistochemistry for IFN-γ, TNF-α, IL-2, IL-7, IL-12, and IL-13. (3) Results: The distribution of cytokines was higher overall in the cleft affected epithelium compared to the connective tissue, with TNF-a, IL-2, and IL-12 displaying the highest number of immunopositive cells. With the exception of IL-2, CL specimen showed higher immunoreactivity. IFN-γ displayed only minor immunoreactivity, with no expression in the control epithelium. Correlation analysis was strongest between CL epithelial IL-13 and IFN-γ (z = 0.71, p < 0.0001). (4) Conclusions: The CLP affected epithelium displays high degrees of plasticity in expressing different cytokines, pointing towards the stimulation of a local adaptive immune response based on consistent inflammatory processes.

Objective To evaluate three-dimensional changes in nasal morphology in patients with unilateral cleft lip and palate treated with presurgical nasoalveolar molding (NAM) to correct naso-labio-alveolar deformity. Design This was a prospective, longitudinal study. Digital stereophotogrammetry was used to capture three-dimensional facial images, and x, y, and z coordinates of 28 nasal landmarks were digitized. Sample Ten patients with unilateral cleft lip and palate. Main Outcome Measures Nasal form changes between T1 (age: 28 ± 2 days, pre-NAM) and T2 (age: 140 ± 2 days, post-NAM), using conventional measurements and finite-element scaling analysis. Results Overall nasal changes were statistically different (p < .01), but no linear or curvilinear changes were found. Specifically, relative size increases were found on the noncleft side, involving the upper nose (30%), alar depth (20%), alar dome (30%), columella height (30%), and lateral wall of the nostril (17%). On the cleft side, the following showed a size increase: upper nose (8%), alar dome (5%), columella height (30%), and lateral wall of the nostril (30%). The cleft-side alar curvature, however, showed a large decrease in size (80%), but no changes on the noncleft side were found. Corresponding shape changes and angular changes were also found. Conclusions Using NAM, bilateral nasal symmetry in patients with unilateral cleft lip and palate was improved before surgical repair. Furthermore, slight overcorrection of the alar dome on the cleft side using pressure exerted by the nasal stent is indicated to maintain the NAM result.

Objective: The aim of the study was to visualize different soft tissues in the perioral, nasal, and paranasal region by means of magnetic resonance imaging (MRI) in patients with unilateral cleft lip and palate (UCLP). Design: In this descriptive study, images of different MRI systems were assessed and compared. Method: MRI was applied in five consecutive patients operated on for UCLP who underwent secondary lip and nasal correction, two patients who had not had UCLP operations, and five healthy volunteers as controls. The mimic muscles, vessels, and nasal cartilages were evaluated. Results: It was possible to visualize different parts of the paranasal and perioral mimic muscles and their interlacement in the upper lip. The nasal cartilages were also visible, and the changes after operation were demonstrated. Conclusions: MRI shows differentiated visualization of soft tissues in the cleft region and their changes after surgery. It is a valuable tool in the preoperative planning and postoperative follow-up in patients with UCLP.

Background and Purpose: The study of nasal changes in cleft lip and palate (CLP) orthognathics is limited. This study aimed to determine differences in 3-dimensional (3D) nasal changes for unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) patients after Le Fort I advancement. Methods: This study was a retrospective cohort evaluation of 18 subjects (9 male, 9 female) treated at a single institution over a 5-year period who had class III skeletal and dentoalveolar malocclusion related to non-syndromic cleft lip and/or palate and underwent surgical correction via Le Fort I osteotomy. Patients underwent pre- and postoperative cephalometric measurements and 3D volumetric assessment for comparison to analyze nasal changes. Statistical analysis was performed to determine changes in nasal parameters using student’s t-test and multivariate analysis. Differences were considered significant for P-values ≤.05. Results: All nasal parameters except for nasolabial angle and nasal length changed significantly postoperatively in the entire cohort. Alar base and flare width both increased significantly (2.1 mm, P = .0002, 1.4 mm, P = .0005), while both relative and total tip projection decreased (−3.4 mm, P = .000004, −2.2 mm, P = .0008). An advancement of the entire nasal complex was seen postoperatively (1.0 mm, P = .0005). UCLP patients had a significantly larger decrease in total nasal tip projection following surgery relative to BCLP patients (−3.5 ± 1.2 mm, −0.8 ± 2.1 mm, P = .008). BCLP morphology increases the degree of 3D nasal surface area advancement relative to UCLP (1.2 mm ± 0.3, 0.8 mm ± 0.6, P = .028). Alar cinch stitch decreases nasolabial angle ( P = .024) but increases nasal length ( P = .004). Conclusion: Discrepancies exist in nasal changes after Le Fort I advancement between UCLP and BCLP patients. Increased understanding of outcomes for cleft patients undergoing Le Fort I can help improve the predictability of nasal esthetic changes in this patient population.
