ObjectiveTo investigate the effectiveness of the mortise-tenon orbicularis oris muscle flap for philtrum column deformity secondary to the unilateral cleft lip repair. MethodsBetween January 2009 and August 2011, 43 patients with philtrum column deformity secondary to unilateral cleft lip repair were treated. There were 23 males and 20 females with an average age of 23.6 years (range, 18-31 years). The left philtrum column was involved in 26 cases, and the right side in 17 cases. Cleft lip was repaired with Millard I in 15 cases and with Millard II in 28 cases. The time between cleft lip repair and philtrum column deformity correction was 15-30 years (mean, 21.7 years). The bilateral double orbicularis oris muscle flap was obtained, and then was divided horizontally into two layers. The overlapping suture of the bilateral lower muscle flap was perfomed, and the upper layer muscle was designed into the mortise-tenon orbicularis oris muscle flap and was sutured with contralateral skin. ResultsAll incisions healed by first intention. Forty cases were followed up 13.4 months on average (range, 6-34 months). The patients achieved satisfactory effects in bilateral symmetry philtrum column and normal concave shape. At 6 months after operation, significant improvement was observed in 38 cases and no obvious improvement in 2 cases. ConclusionThe mortise-tenon orbicularis oris muscle flap is a simple operation and can obtain good results in the appearance and function of the upper lip in the correction of philtrum column deformities secondary to the unilateral cleft lip repair.
Objective To investigate the application and curative effect ofnasoalveolar molding plate in the presurgical orthodontic treatment of completeunilateral cleft lip and palate in infants. Methods From January 2003 to March 2004, 100 infants with complete unilateral cleft lip and palate received presurgical orthopedics by using nasoalveolar molding plate. According to the age, 100 infants(aging 10 days to 3 months, including 60 males and 40 females) were divided into the test group (10 days to 1 month) and the control group (1.3 months). The widths of lip cleft and dentoalveolar cleft and the rate of satisfaction for nose wing were compared between 2 groups before treatment and after the treatment.Results The widths of cleft lip and dentoalveolar cleft before orthodontic (5.0±1.6 mm,6.9±2.6 mm) and after orthodontics (4.1±2.7 mm, 6.4±29 mm）in the test group were less than those in the controlgroup（7.5±3.1 mm, 12.5±4.0 mm and 8.3±3.0 mm,10.8±2.6 mm）, being statistically different(Plt;0.05). The satisfactory rate of nose wing inthe test group (86.3%) was significantly higher than that in the control group(62.4%，Plt;0.05). Conclusion The advantagesof presurgical orthodontic treatment of complete unilateral cleft lip and palate in infants are as follows: repositioning the premaxillary segment, reducing the width of palate cleft, correcting the nasal deformities and facilitating surgical repair of cleft lip and palate.
Objective To analyze the significance of operation date in clinical path designing of cleft lip-palate. Methods The case records of cleft lip-palate patients from 8 hospitals in Gansu province were collected from 2005 to 2008. By means of comprehensive analysis of case records and frequencies of hospitalization duration, analyzed the influence of operation date selection on hospitalization duration in clinical path designing. Result In Gansu province, the average hospitalization duration of cleft lip-palate was 11 days, and the operation was usually done at the sixth day. The main preparations for operation were kinds of examinations. Within five days after operation, most treatments were postoperative care, diet and antibiotic therapy. Conclusion The strategy of operation date selection is much important to ascertain the real hospitalization duration in clinical path designing.
ObjectiveTo investigate the effectiveness of double buried suture method for correction of secondary mild unilateral cleft lip nose deformity. MethodsBetween June 2010 and June 2012, 20 patients with secondary mild unilateral cleft lip nose deformity were treated with double buried suture method. Among 20 patients, 12 were male and 8 were female, with an average age of 21 years (range, 14-44 years). All patients had unilateral cleft lip nose deformity after unilateral cleft lip repair, including 9 cases of left deformity and 11 cases of right deformity. The time between first repair and double buried suture was 11-42 years (mean, 19 years). ResultsIncisions healed by first intention, and no related complication occurred. The patients were followed up 6-12 months (mean, 8 months). All patients were satisfied with the nasal contour, symmetrical projection of the alar dome, a central columella, symmetry of nasal floor, and no obvious scar. No recurrence was observed during follow-up. ConclusionDouble buried suture method not only can correct secondary mild unilateral cleft lip nose deformity completely, but also can avoid obvious scarring and recurrence of nose deformity.
ObjectiveTo explore the effectiveness of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip. MethodsBetween September 2009 and January 2014, 350 patients with secondary nasal deformity of cleft lip were treated, including 160 males and 190 females with a mean age of 18.2 years (range, 16-56 years). Nasal deformity was caused by unilateral cleft lip in 200 cases and by bilateral cleft lip in 150 cases. The interval of lip repair and nasal deformity correction was 2-50 years (mean, 12 years). About a 2-6 cm cartilage was harvested from the 6th or 7th costal cartilage, and was engraved to the shape of "ge" in Chinese. The upper part was strengthened on both sides of the alar cartilage; the lower part was fastened to columella and nasal septum cartilages. The rest of cartilages was diced into 0.1 mm×0.1 mm×0.1 mm cubes. The columella incision was designed to "Z"-plasty, and was stretched to the nasion along alar edge. The engraved autologous costal cartilage was transplanted and fixed to the collapse of nostril. The cartilage cube was transplanted and filled into the collapse of nasal root to achieve the aesthetic effect of nasal augmentation. The effectiveness was evaluated according to the grade of secondary rhinoplasty for cleft lip by ZHANG Li et al. at 1, 6, and 12 months after operation. ResultsAll incisions were primary healing. All patients were followed up 1-12 months (mean, 6 months). After rhinoplasty, the collapse of nostrils was lifted, and the shape and height of collapse of nostrils were symmetrical to normal side. The deflection of columella nasi was corrected. A beautiful shape of nose was achieved. The excellent and good rates were 98.6% at 1 month, 97.4% at 6 months, and 97.1% at 12 months after operation, showing no significant difference (χ2=0.545, P=0.761). ConclusionThe technique of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip can achieve excellent surgery effect.
ObjectiveTo determine teratogenicity of beta-blockers in early pregnancy. MethodsWe searched PubMed, EMbase, Cochrane Clinical Trials, clinicaltrials.gov, CBM, Wanfang database, and CNKI from establishment of each database to December 2014. We evaluated the quality of included literature. Statistical analysis was conducted in RevMan5.3 software. ResultsFifteen population-based case-control or cohort studies were identified. The score of included studies changed from 5-7 points. Based on meta-analysis, first trimester oral beta-blocker use showed no increased odds of all or major congenital anomalies. While in analysis examining organ-specific malformations, statistically increased odds of cardiovascular (CV) defects with OR 2.21 and 95% CI 1.63 to 3.01, cleft lip/palate (CL/P) with OR 3.11 and 95% CI 1.78 to 9.89, and neural tube (NT) defects with OR 3.56 and 95% CI 1.19 to 10.67 were observed. ConclusionCausality is difficult to interpret given small number of heterogeneous studies and possibility of biases. Given the frequency of this exposure in pregnancy, further research is needed.
The cleft lip and palate (CLP) is one of the most common craniofacial malformations in humans. We collected functional magnetic resonance data of 23 CLP patients before rehabilitation training (Bclp) and 23 CLP patients after rehabilitation training (Aclp), who were performing Chinese character pronunciation tasks, and performed brain activation analysis to explore the changes of brain mechanism in CLP patients after articulation disorder rehabilitation training. The study found that Aclp group had significant activation in the motor cortex, Broca area, Wernicke area and cerebellum. While the Bclp group had weak activation in the motor cortex with a small activation range. By comparing the differences and co-activated brain regions between the two groups, we found that rehabilitation training increased the activity level of negatively activated brain areas (cerebellum, left motor area, Wernicke area, etc.) to a positive level. At the same time, the activity level of weakly activated brain areas (right motor area, Broca area, etc.) was also increased. Rehabilitation training promoted the activity level of articulation-related brain regions. So that the activation intensity of articulation-related brain regions can be used as a quantifiable objective evaluation index to evaluate the effect of rehabilitation training, which is of great significance for the formulation of rehabilitation training programs.
