Cleft lip and palate patients show midface hypoplasia, maxillary hypoplasia due to scar of previous surgery, and manifest as a class III malocclusion, retruded midface and shallow palate. These deformities have been treated with traditional orthognathic surgery. Although conventional Le Fort I osteotomy was performed on most cleft patinets with midface hypoplasia, it showed limited amount of maxillary advancement and high relapse tendency. Recently, when great amount of advancement are required in severe maxillary hypoplasia, distraction osteogenesis using RED system is widely used. But, several months of consolidation period is needed after distraction osteogenesis, occlusal relationship is not stable until mandibular setback surgery has done in mandibular hyperplasia cases and during these period, patients may feel discomfort. We present clinical cases of immediate rigid internal fixation after completion of maxillary distraction using RED system and simultaneous mandibular setback procedure in adult cleft and lip patients who show both maxillary hypoplasia and mandibular prognathism.

In order to find the causes of velopharyngeal incompetency after primary palatorrhaphy in cleft patients, we analyzed the form and function of the velopharyngeal space of fifteen operated cleft palate patients and five normal subjects. The velopharyngeal function was evaluated by lateral cephalometric radiography, velopharyngography and hypernasality cul-de-sac test. The obtained results were as follows. 1. The rate of velopharyngeal incompetency was twenty percent, three of the fifteen operated patients. Two of them were complete cleft palate and the other was incomplete one. 2. The length of soft palate and levator eminence were longer in normal group than those of good speech group and complete cleft palate group during phonation of /i/ (P<0.05). The lengthening rate of soft palate was smaller in good and poor speech group than that of normal group(P<0.05), and, reduced in order, normal group, complete cleft palate group and incomplete palate group(P<0.05). 3. The nasopharyngeal distance had no significant difference between all groups at rest, but, smaller in normal group than that of both cleft palate group(P<0.05), good speech group and poor speech group(P<0.05) during phonation of /i/ The difference in nasopharyngeal distance between rest and /i/ phonation was greater in normal group than that of both cleft palate group, good speech group and poor speech group. 4. The moving distance of sop palate reduced in order, normal group, incomplete cleft palate group, complete cleft palate group(P<0.05). 5. The distance between lateral pharyngeal wall had no significant difference between all groups in rest, but, smaller than that of complete cleft palate group in normal group(P<0.01) and increased in order normal group, good speech group, poor speech group(P<0.01) during phonation of /a/. The mobility of lateral wall was reduced in order, normal group, good speech group poor speech group(P<0. 01). 6. There was low corelationship between the mobility of lateral pharyngeal wall and soft palate. Therfore, it suggest that the movements of lateral pharyngeal wall and soft palate occurs independently.

Background: The submucous cleft palate (SMCP) is a type of cleft palate that may result in velopharyngeal insufficiency (VPI). Palate muscles completely separate oral and nasal cavities by closing off the velopharynx during functional processes such as speech or swallow. Also, hypernasality may arise from anatomical or neurological abnormalities in these functions. Treatments of this issue involve a combination of surgical intervention, speech aid, and speech therapy. This case report demonstrates successfully treated VPI resulted from SMCP without any surgical intervention but solely with speech aid appliance and speech therapy. Case presentation: A 13-year-old female patient with a speech disorder from velopharyngeal insufficiency that was caused by a submucous cleft palate visited to our OMFS clinic. In the intraoral examination, the patient had a short soft palate and bifid uvula. And the muscles in the palate did not contract properly during oral speech. She had no surgical history such as primary palatoplasty or pharyngoplasty except for tonsillectomy. And there were no other medical histories. Objective speech assessment using nasometer was performed. We diagnosed that the patient had a SMCP. The patient has shown a decrease in speech intelligibility, which resulted from hypernasality. We decided to treat the patient with speech aid (palatal lift) along with speech therapy. During the 7-month treatment, hypernasality measured by a nasometer decreased and speech intelligibility became normal. Conclusions: Surgery remains the first treatment option for patients with velopharyngeal insufficiencies from submucous cleft palates. However, there were few reports about objective speech evaluation pre- or post-operation. Moreover, there has been no report of non-surgical treatment in the recent studies. From this perspective, this report of objective improvement of speech intelligibility of VPI patient with SMCP by non-surgical treatment has a significant meaning. Speech aid can be considered as one of treatment options for management of SMCP.

Several kinds of surgical methods have been used to treat the submucous cleft palate with hypernasality. The purpose of this study was to evaluate the double opposing Z-plasty which is one of the newly established surgical methods by Dr. Furlow in three cases of submucous cleft palate with hypernasality operated in this department. There were a number of advantage of double opposing Z-plasty. The surgery is adaptable for use in early patient. Midfacial growth retardation and complication were not seen in all cases. Hypernasality was improved subjectively. Using the nasometer, the nasalance score of the postoperative period was compared with that of before surgery, much improvement were noted in 'Ah', 'PaPa'. And fiberoptic endoscope was used to evaluate the velopharyngeal closure pattern. Velopharyngeal closure pattern with velum was improved dramatically, Double opposing Z-plasty seem to be a good procedure for the treatment of submucous cleft palate with hypernasality.

The cleft lip and palate charity operation team visited Binh Duong General Hospital in Vietnam from 17th Dec to 25th Dec 2004. Total 25 cleft lip and palate patients (male : female = 15:10) were undergone the operation. The mean age of the patients was 13.6 year. The types of surgical operation were primary cheilorrhaphy (8 cases), primary palatorrhaphy(10 cases), pharyngoplasty(2 cases), scar revision(3 cases), alveolorrhaphy(2 cases). There were no intraoperative and immediate postoperative complications. The year 2004 was the 10th charity operation in the same area so it is meaningful to review the start of this charity mission and the course, and the future of our activity.

This study evaluated and compared the donor site morbidity following minimally invasive and conventional open harvesting of iliac bone for secondary alveolar bone grafting in cleft palate patients. A thorough electronic search of PubMed, Google Scholar, EMBASE, and an institutional library and manual search of various journals was done; Inclusion criteria: 1) full-text articles using a minimally invasive or conventional open harvesting technique for iliac bone for secondary alveolar grafting in cleft palate patients and 2) articles published between January 1, 2001 and June 30, 2017 and Exclusion criteria: 1) articles published in languages other than English, 2) case reports, case series, animal studies, in vitro studies, and letters to the editor, and 3) full-text article unavailable even after writing to the authors. Preliminary screening of 274 studies excluded 223 studies for not meeting the eligibility criteria. Of the remaining 51 studies, 19 were removed for being duplicates. Of the remaining 32 studies, 15 were excluded after reading the abstract. Of the 17 studies that were left, 2 were excluded because they were in a language other than English, and 2 were excluded because the study group did not mention cleft palate patients. Thus, 13 studies providing results for a total of 654 patients were included in this qualitative synthesis. Minimally invasive bone graft harvest techniques are better than the conventional open iliac bone harvest method because they offer shorter operative time, decreased requirement for pain medications, less pain on discharge, and a shorter hospital stay.

Cleft palate patients with congenital anomalies have an increased risk of airway problems following palatoplasty. Factors that were related included presence of associated congenital anomalies, duration of surgery, age at time of surgery, history of previous airway problem, and excessive pressure exerted on the base of the tongue by Dingman retractor. This report described a complication of post-operative Pneumonia after palatoplasty (Furlow technique), which resulted in a life-threatening acute airway obstruction in an infant with cleft palate. Patient has a history of previous mild airway problems. In addition to this problem, we speculate that Furlow technique involves more extensive surgical dissection than other techniques may increase risk for upper airway obstruction. Awareness of this risk permits identifying those patients prior to surgery so that they can be monitored and managed properly, minimizing the likelihood of major complications or possibility of death.
