Ten cleft palate patients were operated with reconstruction of levator sling without pushback for the purpose of not to make raw surface in the anterior portion of hard palate to prevent maxillary retrognathia. Speech was evaluated by using speech assessment list. Maxillary growth was not evaluated due to in-growing age in majority patient. The report will be followed in next chance. We could impose the significance in clinical application of levator sling palatoplasty without any complications but improving speech.

Small palatal fistulas following surgery for cleft palate can be corrected easily by local mucoperiosteal flap. But fistula repair is difficult if the fistula is large in hard palate. Tongue flaps are the most commonly used flaps for closure of difficult palatal fistulas. The authors treated 38 patients of large palatal fistulas using tongue flap. Among them, 33 patients were operated using posteriorly based tongue flap, and 5 patients were operated using anteriorly based tongue flap. In the former, all flaps were successfully survived and not necessary a fixation of tongue after flap transfer. But in the latter, tongue flap of a patient was detached because of high mobility, and tongue flap of a patient was necrotized because of poor blood supply. For closure of large palatal fistula, posteriorly based tongue flap is safer and more reliable technique than anteriorly based tongue flap considering mobility and blood supply.

Granular cell tumor is a uncommon disease, although head and neck region accounts for approximately 50% of all lesions, 70% are located in oral cavity but can occur at other site of the body. Clinically, it usually presents as a small, slow growing, non-tender, single benign lesion but mutifocal and malignant forms are rarely encountered. The histogenic origin of this tumor was controversial for many years but recent studies using immunohistochemical study support its origin being from neural cell, probably Schwann's cell. In this report, we present a case of benign granular cell tumor occurred on the hard palate studied by histologic and immunohistochemical assay, with review of literatures.

OBJECTIVETo investigate the relation between different extents of cleft malformation with the speech characteristics in patients with cleft palate.

METHODSThe formant frequency of vowel [i] of 46 incomplete cleft palate patients (ICCP group) and 56 complete cleft palate patients (CCP group) before and after cleft palate repair, as well as 30 normal people (C group), were measured and analyzed on spectrogram.

RESULTSThe comparison of F1 between C group and CCP, ICCP before surgery showed no difference. So did the comparison of F1 between C group and CCP, ICCP after surgery. The comparison of F2 between C group and CCP, ICCP before surgery showed significant difference. The value of the C group was the highest. The value of the ICCP was higher than that of CCP. So did the comparison of F2 between C group and CCP, ICCP after surgery. The comparison of F3 between C group and CCP, ICCP(including before and after surgery) was similar to the results of F2 between the three groups. The comparison of F1 between before and after surgery in ICCP group showed no difference. However, the same kind of comparison of F2 and F3 showed significant differences: Both the values after surgery were higher than those before surgery. The comparison of Fl, F2 and F3 between before and after surgery in CCP group was similar to that in ICCP group.

CONCLUSIONThe extent of the cleft malformation is closely related to the status of the speech in patients with cleft palate. With the malformation more severe, the tongue will move backward more obviously, the elevation of the soft palate after cleft palate repair will be less active. Two ways are recommended for those patients with CCP: (1) Early interceptive orthodontic treatment to reduce the extent of palate malformation; (2) The hard palate repair can be performed prior to the soft palate repair. Patients with severe cleft lip and palate can have hard palate repaired while accepting the early cleft lip repair.

palate.TECHNIQUES AND APPROACHES: Four-hundred-sixity patients operated between 1993 and 2008 were included in this study. The collected data were age, sex, operating time, admission days, and complications. The comparison between techniques were done by independent t-test.RESULTS: The majority (86.9 %) of patients were received the operation later than 1.5 years old. The distribution of each surgical technique was 43.8 % by Bardach palatoplasty, 11.9 % by Furlow palatoplasty, 1.8 % by Veau palatoplasty, and 42.4 % by the new technique developed by us. Postoperative complication such as wound dehiscence, formation of oro-nasal fistulas in the soft and hard palates were shown in 23.0 % of Bardach technique, 44.2 % of Furlow technique, and 37.5 % of Veau technique. However, only 5.4 % of patients were shown complications in our technique (P<0.001). The operation time was recorded 70 minutes under new technique while the others were 110 minutes (P<0.001). The clinical treatment at hospital was required 7.4 days for our technique and 11.3-15.5 days for the other methods.CONCLUSION: The surgical treatment of congenital cleft palate in Mongolia was conducted later than proper timing for surgery. As the results were indicated, our new technique should be considered for the correction of cleft palate in old aged patients.]]>

Furlow's palatoplasty has been used as the primary treatment for cleft palate. From 1991 to 1999, 24 submucous cleft palate patients underwent Furlow's palatoplasty. The follow-up period was 3 months to 8 years (mean 24 months). Patients were selected after a thorough study for velopharyngeal insufficiency including intraoral examinatioin, speech assessment, digital subtraction radiography (DSR). Postoperatively velopharyngeal function was reevaluated with speech assessment and digital subtraction radiography in the 7 cooperative patients. Speech parameters including hypernasality, nasal emission, and Allison scale were improved after surgery. Digital subtraction radiography provided the value of velopharyngeal gap and the degree of the motion of lateral pharyngeal wall, both of which were improved after surgery. Furlows palatoplasty has advantage such as no impairment of nasopharyngeal physiology, no hannful effect on the hard palate and the realignment of the levator muscle which plays important role on the movement of the soft palate. The results show that a Furlow's palatoplasty can satisfactorily correct velopharyngeal insufficiency in carefully selected submucous cleft palate patients.

The purpose of this study is to introduce the method of palate repair that combines minimal hard palate dissection and radical retropositiong of levator musculature, which was presented by Sommerlad. As this method presents, additional use of the operating microscope enables atraumatic and radical dissection, and it might provide more improved speech function to the patients. A total of 17 patients with cleft palate underwent Sommerlad's method from December 2003 to August 2004. The mean follow-up period was 4.5 months. The use of a microscope provided high quality variable magnification and good illumination at the operating field. Repair was carried out through incisions at the margins of cleft with mucoperiosteal flap elevation. Muscles were rearranged and repaired properly. It was unable to evaluate the improvement of speech because the patients were too young to learn meaningful speech. Average operating time including anesthetic induction time, V-tube insertion and recovery from anesthesia was 2 hours 45 minutes which was not quite different from conventional method's operating time. Oronasal fistula developed in 2 patients of them. One of them was healed spontaneously. As meticulous and radical muscle dissection was possible with Sommerlad's method, we could minimize the trauma to the muscular and neurovascluar structure. In addition, we expect better faculty of speech as a result of this method although longer follow-up time was unavailable.
