OBJECTIVETo investigate the prevalence of dental anomalies in Chinese children with complete unilateral cleft lip and palate (UCLP).

METHODSDental histories and radiographs of 244 Chinese children with UCLP were collected. The diagnosis of dental anomalies was based on panoramic radiographs before alveolar bone grafting. All patients were over 8 years old.

RESULTSIn the UCLP group, 66.8% of the patients was presented with hypodontia. The maxillary lateral incisors were the most common teeth affected, followed by maxillary second premolars, mandibular incisors and mandibular second premolars. A total of 33.6% the patients was presented with dental malformation, most were microdontic laterel incisors. A total of 4.9% the patients was presented with hyperdontia. The supernumerary teeth were more frequently found in the cleft region. The prevalence of missing maxillary lateral incisor in the noncleft side was statistically different between genders, which was higher in male (P < 0.050). This group of Chinese children with UCLP demonstrated significantly higher prevalence of hypodontia, hyperdontia, and malformation on the cleft side than on the noncleft side (P < 0.01).

CONCLUSIONSHypodontia is the most common type of dental anomalies. The prevalence of dental anomalies is higher in the UCLP patients than in the normal population. Dental anomalies occur more frequently on the cleft side than on the noncleft side.

Dysphasia related to oral anomaly is a common situation in oral and maxillofacial surgery. The etiology of oral anomalies causing dysphasia can be divided into congenital and acquired disease. Congenital diseases include teratoma or benign tumors and congenital defects such as cleft lip and palate. Benign tumors include cystic hygroma in the neck and hemangioma in the tongue. Certain syndromes with macroglossia and micrognathia are also related to difficulty in swallowing. The three common syndromes are Pierre-Robin syndrome, Beckwith-Widermann syndrome and ectodermal dysplasia. Taken together, these congenital diseases require a multi-discipline approach to obtain optimal results. Representative disease of acquired dysphasia is the oral cavity cancer. Cancer ablation results in tissue defect and decreased motor function. Free flap reconstruction is the choice of treatment following oral cavity caner operation; however, dysphasia after cancer operation is inevitable. In this review article, the full scopes of oral anomaly associated with dysphasia were classified and treatment was suggested.

Cleft lip and palate is congenital deformity in oral and maxillofacial area. Normal soft palate has velopharyngeal closure action by connecting oral cavity and nasal cavity at rest and moving upward at swallowing and specific pronunciation. Cleft palate patients with velopharyngeal insufficiency have difficulty in mastication, swallowing and pronunciation because velopharyngeal closure is incomplete. At this time, a prosthetic device used to cover palate defects is called a palatal obturator. A palatal obturator separates oral cavity and nasal cavity and recovers pronunciation, mastication, swallowing and esthetic function. The purpose of this case study is to report the results because it reaches a satisfactory result in functional and esthetic aspects through functional impression procedures using modeling compound and tissue conditioner for restoration of a cleft palate patient with velopharyngeal insufficiency.

OBJECTIVETo investigate the application of the perceptual assessment in the diagnosis of the velopharyngeal function, to provide a reference to the improvement of the velopharyngeal function diagnosis through comparing the consistency between the diagnosis of the perceptual assessment and the objective assessment.

METHODSAll subjects (254) were selected from the Department of Cleft Lip and Palate Surgery, West China School of Stomatology, Sichuan University, from 2000-2010. The results of the perceptual and the nasopharyngeal fiberscope (NPF) assessment were retrospectively analyzed, and the consistent rate between the two assessment methods was calculated. The Kappa test and the correlation analysis were performed to analyze the consistency and correlation, and the factors relating to the perceptual assessment were analyzed by the correlation coefficient.

RESULTSThere were 254 patients met the inclusion criteria. The consistent number of the patients diagnosed by the perceptual and the objective assessment as velopharyngeal competence (VPC) and velopharyngeal insufficiency (VPI) were 58 and 167 respectively. The consistent rate was 88.58% for all patients, and 66.67% for the VPC patients. The Kappa value was 0.721, Spearman's R=0.751, P<0.05. There were correlation between the hypernasality, the nasal emission and the subjective assessment, and Spearman's R=0.697, 0.590, P<0.05.

CONCLUSIONThe VPC patients and the VPI patients with moderate and severe hypernasality and nasal emission diagnosed by the perceptual assessment could be exempt from the objective examination. Patients diagnosed with mild hypernasality and nasal emission by the perceptual assessment should be further referred to NPF or other instruments.

OBJECTIVETo enhance the accuracy in diagnosis and management of submucous cleft palate via a thorough analysis of its anatomical and functional details.

METHODSTwo hundred seventy-six submucous cleft palate cases from 2008 to 2014 were retrospectively investigated. Subgroup analysis were performed on the basis of preoperative velopharyngeal function, palatal morphology, cleft lip concurrence, and patient motives for treatment.

RESULTSAmong the included cases, 96 (34.78%) were presented as velopharyngeal competence (VPC), 151 (54.71%) as velopharyngeal insufficiency (VPI), and 29 (10.51%) as marginal VPI (MVPI). Eighty cases (28.99%) also demonstrated cleft lip deformity, and 196 cases (71.01%) were merely submucous cleft palate. Compared with patients with submucous cleft palate only, those with cleft lips exhibited higher rates of complete velopharyngeal closure. The pathological spectrum of submucous cleft palate varied significantly. Only 103 (37.32%) cases met all the three diagnostic criteria proposed by Calnan.

CONCLUSIONSGiven that the velopharyngeal closure rate varies among the subgroups, the factors analyzed in this study should be considered in the personalized manage-ment of submucous cleft palate.

Although it is a rare developmental malformation, van der Woude syndrome is the most common form of syndromic orofacial clefting, accounting for approximately 2% of all cleft cases. The lower lip pits with or without a cleft lip or palate is characteristic of the syndrome. Findings, such as hypodontia, limb deformities, popliteal webs, ankylogossia, ankyloblepheron, and genitourinary and cardiovascular abnormalities, are rarely associated with the syndrome. This paper reports a rare case of van der Woude syndrome in a 10-year-old male patient with a single median lower lip pit and a repaired bilateral cleft lip and cleft palate that were associated with microstomia, hypodontia, and clubbing of the left foot with syndactyly of the second to fifth lesser toes of the same foot.

Numerous cases of enamel renal syndrome have been previously reported. Various terms, such as enamel renal syndrome, amelogenesis imperfecta and gingival fibromatosis syndrome, and enamel-renal-gingival syndrome, have been used for patients presenting with the dental phenotype characteristic of this condition, nephrocalcinosis or nephrolithiasis, and gingival findings. This report describes a case of amelogenesis imperfecta of the enamel agenesis variety with nephrolithiasis in a 21-year-old male patient who complained of small teeth. The imaging modalities employed were conventional radiography, cone-beam computed tomography, and renal sonography. Such cases are first encountered by dentists, as other organ or metabolic diseases are generally hidden. Hence, cases of amelogenesis imperfecta should be subjected to advanced diagnostic modalities, incorporating both dental and medical criteria, in order to facilitate comprehensive long-term management.

The deformities of micrognathia and glossoptosis in the newborn are frequently associated with a cleft palate, which is known as Pierre Robin sequence. Upper airway obstruction is the most serious problem in these patients. Treatment of Pierre Robin sequence includes either positional or surgical intervention. Mild cases are often managed in the prone position. However, when the patient fails to thrive due to chronic upper airway obstruction, or severe respiratory distress ensures despite positional treatment, surgical intervention is mandatory to relieve the obstruction. We experienced three infants with Pierre Robin sequence who showed a symptom triad of micrognathia, glossoptosis, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty and feeding problems were also observed. To relieve severe upper airway obstruction caused by micrognathia and glossoptosis, we simultaneously performed modified tongue lip adhesion (TLA) and a subperiosteal release of the floor of the mouth (SRFM). Respiratory and feeding difficulties were relieved, the tongue positioned anteriorly, body weight increased, and mandibular growth improved. Simultaneous TLA and SRFM may constitute a simple and reliable method for surgical treatment of airway obstruction in patients with Pierre Robin sequence.

BACKGROUND: Maxillary hypoplasia refers to a deficiency in the growth of the maxilla commonly seen in patients with a repaired cleft palate. Those who develop maxillary hypoplasia can be offered a repositioning of the maxilla to a functional and esthetic position. Velopharyngeal dysfunction is one of the important problems affecting speech after maxillary advancement surgery. The aim of this study was to investigate the impact of maxillary advancement on repaired cleft palate patients without preoperative deterioration in speech compared with non-cleft palate patients. METHODS: Eighteen patients underwent Le Fort I osteotomy between 2005 and 2011. One patient was excluded due to preoperative deterioration in speech. Eight repaired cleft palate patients belonged to group A, and 9 non-cleft palate patients belonged to group B. Speech assessments were performed preoperatively and postoperatively by using a speech screening protocol that consisted of a list of single words designed by Ok-Ran Jung. Wilcoxon signed rank test was used to determine if there were significant differences between the preoperative and postoperative outcomes in each group A and B. And Mann-Whitney U test was used to determine if there were significant differences in the change of score between groups A and B. RESULTS: No patients had any noticeable change in speech production on perceptual assessment after maxillary advancement in our study. Furthermore, there were no significant differences between groups A and B. CONCLUSIONS: Repaired cleft palate patients without preoperative velopharyngeal dysfunction would not have greater risk of deterioration of velopharyngeal function after maxillary advancement compared to non-cleft palate patients.
