Submucous cleft palate is a relatively uncommon congenital anomaly accompanying velopharyngeal incompetence(VPI). Double opposing Z-plasty has many advantages including prolongation of soft palate, normal midfacial growth, midline scar. We analyzed postoperative results comparing with those of preoperative evaluation by several variables(nasometer, endoscopy, satisfactory scale) in 14 patients treated with double opposing Z-plasty due to submcous cleft palate. Nasalance score in Ah sound, Ma phrase, and Pa phrase decreased 20.23%, 3.25%, and 23.26% in the average, respectively. As a result, hypernasality improved significantly. Closure rate in velum evaluated by endoscopy was increased from 0.44 to 0.76. In objective satisfactory scale checked by each patient's guardian at the postoperative period, much improved in 3, improved in 6, minimally improved in 1, and no difference in 1 was reported. (n=11 patients) Double opposing B-plasty is a good surgical modality in patients accompanying VPI with submucous cleft palate or incomplete cleft palate and will be used more usefully and widely.

The classic triad of diagnostic signs of submucosal cleft palate which may be present are: 1) bifid uvula 2) short palate with no muscle in the midline and 3) hard palate with a submucous notching defect in the posterior midline. The treatment of submucous cleft palate are V-Y push back palatorrhaphy, and superior based pharyngoplasty implant in the posterior pharynx. The best speech results were in those children operated upon in the younger age group (especially at or before 2 years of age), thus pointing up the importance of early diagnosis.

A submucous cleft palate(SMCP) is characterized by a midline deficiency or lack with/without incorrect positioning of muscular tissues in the soft palate, and by a bony defect in the midline or the center of the hard palate. Velopharyngeal incompetence(VPI) related to this SMCP has been managed by various surgical and prosthetic techniques. Because the individual diagnosis and treatment of SMCP patients was not easy to the speech pathologist and to the maxillofacial reconstructive surgeons, and for the better understanding and for the ideal approaches to the SMCP patients, we reviewed several recent articles about grading system in the SMCP caused by VPI, and summarized in this review article.

Velopharyngeal insufficiency (VPI) is a phenomenon that can occur due to anatomical or neurological causes of the soft palate. VPI can make the patient difficult to articulate through hypernasality and nasal emission. There has been needed the customized treatment, as VPI can occur for many causes. We present the case of 21-year-old male who took palate plastic surgery 20 years ago for congenital submucosal cleft palate. As he had poor contraction of both lateral side of velopharynx, he was diagnosed with coronal type VPI. Through sphincter pharyngoplasty, he can obtain improvement of articulation accuracy. We would like to share this challenged case.

Submucosal type cleft palate is subdivision of cleft palate. Because of late detection, the treatment - for example, the operation or the speech therapy - for the submucosal type cleft palate patient usually late. In this study, we want to find the objective characteristics of submucosal type cleft palate patient, comparing with the normal and the complete cleft palate patient. Experimental groups are 10 submucosal type cleft palate patients who got the operation in our hospital, 10 complete cleft palate patients. And, 10 normals as control group. The sentence patterns using in this study is simple 5 vowels. Using CSL program we evaluate the Formant, Bandwidth. We analized the spectral characteristics of speech signals of 3 groups, before and after the operation.
