“…In several case reports and case series, they cite variations and new methods of stabilizing the premaxilla, however, needs further investigation and clinical analysis. 7,[14][15][16][17][18] Another point of interest to be addressed is the large number of articles excluded from this study in the eligibility process for not mentioning the premaxilla stabilization method used, which demonstrates the negligence of inserting this stage in the studies despite its importance in the success of the treatment.…”

Objective Verify the effectiveness of surgical repositioning of the premaxilla and its stabilization methods in patients with bilateral cleft lip and palate during mixed dentition. Design Systematic review. Material and Methods The search was conducted in 7 databases (eg, Medline via PubMed; Scopus; Central Cochrane; LILACS; Embase, Web of Science; and Sigle via OpenGrey until August 2021), using the descriptors “premaxilla”, “cleft Palate”, and “bone transplantation”. Inclusion criteria Clinical trials and observational studies that have patients with bilateral cleft who had a need for superior/posterior repositioning of the premaxilla on mixed dentition; Studies in any language was evaluted whitout time restriction of publication. Results From 5572 records, 6 studies were included in the review with a total sample of 212 patients. Regarding the type of stabilization used in the premaxilla, the hybrid method (rigid and complementary semi-rigid stabilization) predominated, being observed in 184 patients (86.8%). A total of 17 failures were identified related to the surgical repositioning of the premaxilla, corresponding to 8% of the total number of surgeries. A meta-analysis of prevalence was performed, only with the retrospective studies. It was observed that the effectiveness rate of premaxilla repositioning was 92%, with a CI between 0.04 and 0.13, with all included studies showing a similar failure rate (0.08-0.09). The included studies also showed great homogeneity in this analysis (I2 = 0%; P = .75). Conclusion Although there are several alternatives and techniques for repositioning and stabilizing the premaxilla, the statistical result did not differ between the different techniques.

“…Despite continuously improving cheiloplasty/cheilorhinoplasty techniques, along with pharmacological and other wound healing technologies, an incidence of long-term postoperative complications of this pathology remains quite high [9,10]. As a result, an absolute majority of primary patients who underwent cheilorhinoplasty require repeated corrective interventions [11,12].…”

Oropharyngeal Dysbiosis Affects Postoperative Tissue Reparative Capacity In Patients With Congenital Disorders Of Maxillofacial Region

et al. 2021

Background — One of the main causes of hyperergic postoperative tissue response could be a prolonged opening in the septum between normally isolated anatomical regions, e.g., of the nasal cavity and oropharynx in patients with congenital disorders of maxillofacial region, which leads to anomalous exchange of their microbiotas. Objective — The objective of this study was to determine the composition of culturable facultative anaerobic microbiota of oronasopharyngeal mucosa, and to identify cytokine profiles in patients with congenital disorders of maxillofacial region in both preoperative and postoperative periods. Methods and Results — Our study is based on the results of examining the children with unilateral congenital cleft of upper lip (CL) before and after surgery, as well as examining the children with simultaneous unilateral congenital cleft of upper lip and palate (CLP) before and after primary rhinocheiloplasty. We used ELISA to determine the content of interleukin-10 (IL-1β) and interleukin-10 (IL-10) in the samples of blood serum and mucosal surfaces. The study of culturable microflora was conducted in patients before the surgery and during a postoperative period, specifically at one, three, six, and twelve months. Isolation of pure bacterial cultures was performed via conventional bacteriological methods followed by identification using MALDI-TOF testing. Before the surgery, microbial colonization was observed at significantly higher levels in CLP children than in healthy children. After the surgery, microbiological indicators partially came to normal values solely in CL patients. Local IL-1β concentrations remained significantly higher than those found in healthy subjects. In terms of postoperative dynamics, blood plasma antioxidant activity declined below normal values in CLP patients. Conclusion — Our study demonstrated the need for preoperative eradication of potential pathogens (e.g., Staphylococcus aureus, Klebsiella spp., Candida spp. and Streptococcus spp.), preferably, via using non-antibiotic approaches, such as probiotics and phage therapy, as well as supportive integrative therapy (e.g., using antioxidants).

Ⅰ．IntroductionSome patients with bilateral cleft lip and palate (BCLP)have premaxilla malposition and require premaxilla repositioning surgery during orthodontic treatment. However, there is no consensus on the method of premaxilla fixation. Some articles have reported on bone level fixation using plates and screws 1) or wires 2) , whereas other articles have reported on dentition level fixation by splints 3 6) . However, problems remain in terms of fixation strength, oral hygiene, and influence of feeding, among others. There is also no unified opinion on the superior technique of alveolar bone grafting (ABG) , in terms of the number of surgeries and maintenance of blood flow to the mucosa between the one stage method, in which both sides are grafted at the same time, and the two stage method, in which each side is grafted at different times. In this article, we introduce our institutionʼs technique for premaxillary osteotomy(PO)and ABG, focusing on the fixation of the premaxilla and the postoperative course of the pro-cedure. Ⅱ．Methods １．PatientsThis study was approved by Institutional Review Board (IRB approval number D2020 085) . We included 9 patients with BCLP and a patient with bilateral cleft lip and alveolus who underwent ABG with PO in our institution between 2002 and 2020(Table 1) . All operations were performed by an experienced senior surgeon. Patient age at surgery ranged from 6 to 25 years for the first stage surgery. The cleft width was measured as the narrowest cleft width in the preoperative horizontal CT section. The methods for evaluation of bone bridging are described in a previous report, i.e., score 4, 0 to 25％；score 3, 25 to 50％；score 2, 50 to 75％；and score 1, 75 to 100％ 7) . ２．Treatment protocols ABG was usually performed in two stages, considering the blood flow in the premaxilla, except for two cases. Bilateral alveolar bone grafts were performed at
