JOURNAL FREE ACCESSA statistical investigation of impacted teeth in permanent dentition (except the third molar) was carried out in 116 patients with cleft lip and/or cleft palate who were treated in our clinic between April 1,1989., and March 31,1994. The results were as follows:
1) Forty-seven impacted teeth were noted in 23 (19.8 %) of 116 patients.
2) Impacted teeth were present in the maxilla alone in 11.2 %, in both the maxilla and mandible in 5.2 %, and in the mandible alone in 3.4 % of the patients. Twenty-nine impacted teeth were in the maxilla, and 18 were in the mandible.
3) Of the impacted teeth,31.9 % were the lower second bicuspids,27.7% were the upper second bicuspids, and 10.6 % were the upper cuspids.
4) The frequency of numerical anomalies o f teeth was evaluated in patients with cleft lip and/or cleft palate having impacted teeth. Numerical anomalies were observed in 63.2 % of those with impacted teeth in the maxilla but not in the remaining 36.8 %. None of the patients with impacted teeth in the mandible had numerical anomaly.View full abstractDownload PDF (1251K) -

JOURNAL FREE ACCESSThe intraoperative and postoperative results of hard palate closure were investigated in the case of two-stage palatoplasty in our clinic. Comparative analyses have been made between the results of the cases operated only by using vomer flap (vomer flap group, n=76)and those of the cases operated by using vomer and palatal flaps (vomer+palatal flap group, n=16).
The results were as follows:
1. The blood loss of the vomer flap group (mean: 42.4 g) is significantly less than that of the vomer+palatal flap group (mean: 103.6 g).
2. Only 10 cases (10.9 %) had postoperative fistula. The ratio of fistula formation was not significantly different between the two groups. There was no case with large fistula that causes critical dysfunction such as speech difficulties.
3. Raw surface made by operation have been covered by TERUDERMIS(Artificial dermis made of atelocollagen). There was no case with severe operation scar.
4. It was considered that the usefulness of two-stage palatoplasty can be enhanced by the operation using vomer flap alone, which causes less surgical damage.View full abstractDownload PDF (7033K) -

JOURNAL FREE ACCESSIn an effort to obtain information about effects of speech appliance,52 cases (from 3 to 13 years old) with both misarticulation and hypernasality caused by velopharyngeal incompetence were selected. A speech appliance of PLP type was placed, and its pharyngeal section was gradually extended to the Bulb-attached PLP type when necessary. Changes of velopharyngeal closure via nasopharyngeal fiberscope and hypernasality assessmet were followed after the placement of the appliance, and the results were as follows:
1. Assessments of hypernasality after the placement of speech appliance revealed improvement in 48 cases (92.3 %), i. e., normal in 43 cases (82.6 %) and mild hypernasality in 5 cases (9.6 % ).
2. The cases that showed velopharyngeal mobility during blowing prior to the placement of the appliance tended to show more improvement of hypernasality with the speech appliance, i. e., all of the cases of [bvp] showed normal,89.4 % of cases of [m+] showed normal, and 5.3% were mild hypernasality,65 % of cases of [m-] showed normal and 20 % showed mild hypernasality.
3. In cases who achieved VPC during blowing in less than 2 years with speech appliance tended to show more improvement of hypernasality.
4. Seven cases (13.4 %) achieved norm al (no hypernasality) and velopharyngeal competence with the use of the speech appliance, resulting in removal of those appliances without any relapse of hypernasality and misarticulation.
These results indicated that the use of speech appliance is an effective means for problems with velopharyngeal incompetence.View full abstractDownload PDF (4759K) -

JOURNAL FREE ACCESSA qualitative evaluation of canine tooth migration and bone bridge formation following bone grafting was done.
A total of 105 cases of alveola r bone grafting was done in our clinic between March 1983 and December 1996. Subjects of the study were 26 patients with a total of 31 alveolar clefts, all of which underwent bone grafting. The age range at the time of bone grafting was 8 to 14 years.
The unerupted group had 16 patients with a total of 19 clefts, and the erupted group had 10patients with a total of 12 clefts.
In the unerupted group, the canine location and bone height were measured on radiographs taken pre-and postoperatively. Two clefts underwent surgical exposure and traction for canine migration. The canine of 17 clefts erupted with bone grafting only.
The two groups were compared for bone bridge formation; the unerupted group had the wider, hence better, bone bridge formation than the erupted group.View full abstractDownload PDF (5952K) -

JOURNAL FREE ACCESSThis case report presents the short-term results of the alveolar bone grafting performed at the age of six years five months, the erupting stage of the upper left central incisor in a female with left-sided complete cleft lip and palate. Approximately 5.5 grams of autogenous particulate marrow and cancellous bone (PMCB) harvested from the anterior iliac crest was transplanted. The average alveolar cleft width of this patient was 12 mm. This case had happened to involve closed alveolar cleft using mucobuccal flap; therefore, attached gingiva was insufficient around the alveolar cleft preoperatively. Bony bridging of alveolar cleft was almost completed and trabecullar pattern of the grafted area was normal radiographically three months after surgery. Since the volume of grafted PMCB was thought to be insufficient compared to the bony defect, the nasal border of the bony bridge was slightly decreased. The interdetal alveolar bone height was normal. Forward-downward growth of maxilla was observed on roentgenocephalometric analysis over a three-year period after the bone graft. It was suggested that secondary bone grafting during the eruptive stage of the permanent upper central incisors was beneficial.View full abstractDownload PDF (8242K) -

JOURNAL FREE ACCESSBone grafting of the alveolar cleft region has been widely performed on cleft lip and palate patients at many medical facilities including our own. There are various reports which place emphasis on the objective findings of grafted alveolar clefts. However, subjective comments of the patients regarding the operation and selection of graft material is uncertain. Thus the patient's comment on the operation and the types of graft materials to be used was investigated.
Questionnaires were sent to the 29 patients who underwent this operation at our clinic and 24 replied. The results were as follows.
1) 0 % had knowledge about bone grafting of the alveolar cleft region before it was explained to them.
2) The pat ients' decisions regarding the operation were consulted with father in 67 %, mother in 79 %, and orthodontist in 38 % of the cases, and 4 % did not consult anyone regarding this matter.
3) 96 % were satisfied with the graft material and the choice of operation method.
4) 87 % appreciated the informed consent obtained by the doctors but 9 % d id not.
The decision concerning the surgical method and the graft material to be used are agreed upon by the patient, parents, and the doctor. Careful explanation of the advantages and disadvantages of different surgical methods and graft materials is mandatory in the decision making. This survey suggested that it is critical to inform the patient about the graft materials and the surgical methods and ample time should be given for them to make a decision.View full abstractDownload PDF (1248K) -

JOURNAL FREE ACCESSCornelia de Lange syndrome (CDLS) is characterized by characteristic faces, multiple congenital malformations, and mental retardation. In the oral region, micrognathia and high arched palate were found in most cases and 20-30 % of the cases were associated with cleft palate.
Two cases of CDLS's cleft palate surgery, which we experienced recently, were reported.
One case was a 3-year 7-month-old female (BW: 6,700 g) and the other was a 13-year-old female (BW: 19,900 g). Both children had no language development, but cleft palate closure was performed the push back method under general anesthesia. The timing for the operation was recommended after conference with pediatricians and anesthetists. There were no complications in terms of perioperative management. After the cleft palate operation, because of mental retardation, no improvement was found in language development. However both children seemed to have a good appetite without food impaction in the palate or to the nasal cavity.View full abstractDownload PDF (5640K) -
