  • 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.

  • The aim of present study was to assess the thickness of masticatory mucosa on the hard palate and tuberosity as a potential donor site for mucogingival surgery. Thickness measurement was performed in 30 dental college students who are periodontally healthy, with a recently developed, ultrasonic device(SDM). The mean age of study subjects was 23.7(range 21-29) years old and the subjects were composed of 18 males and 12 females. Eighteen standard measurement points were defined on the hard palate, located on 3 lines which ran at different distances parallel to the gingival margin. Six positions were designated on each of these 3 lines between the level of the canine and the second molar. On the tuberosity, 6 standard measurement points were defined, located on 2 lines running parallel to the gingival margin at different distances. Data were analyzed to determine differences in gender, between different positions, and between lines, by an analysis of variance. The results showed that the mucosa of the tuberosity was significantly thicker than that of the hard palate region. Gender did not influence the thickness of masticatory mucosa, either on the hard palate or the tuberosity. On the hard palate, mucosa thickness increased as the distance from the marginal gingiva increased. The mucosa over the palatal root of the maxillary first molar was significantly thinner than that at all other positions on the hard palate. Measurement error at palate was 0.25mm, at tuberosity 0.51mm. No difference in the thickness of masticatory mucosa on palate and tuberosity was found between men and women. On the hard palate, soft tissue thickness progressively increased in sites further from the gingival margin. Therefore, we may harvest more thicker graft on the tuberosity that has more masticatory mucosa thickness than hard palate, however the width may not be sufficient for using.

  • Distraction osteogenesis is useful treatment which the gradual separation of cut bone edges results in the generation of new bone. It is effective treatment for correcting maxillofacial deformities. Patients with cleft lip and palate usually have maxillary hypoplasia due to scarring of lip and palate. To correct these deformities, we chose to use a 2-jaw orthognathic surgery or distraction osteogenesis. But despite improvements in surgical techniques for maxillofacial deformities, postoperative stability still leaves the question of when relapse may occur. This case report describes the Relapse after treatment of maxillary hypoplasia with cleft lip and palate by Rigid External distraction system over a 2-year treatment and follow-up period. In addition, we reviewed related articles about the influence of the occlusal stability on postoperative stability in patients with cleft lip and palate correction with Distraction osteogenesis.

  • Background The postoperative speech outcomes of submucous cleft palate (SMCP) surgery are known to be poorer than those of other types of cleft palate. We attempted to objectively characterize the postoperative complications and speech outcomes of the surgical treatment of SMCP through a comparison with the outcomes of incomplete cleft palate (ICP). Methods This study included 53 SMCP patients and 285 ICP patients who underwent surgical repair from 1998 to 2015. The average age of the patients at the time of surgery was $3.9{\pm}1.9years$ for the SMCP patients and $1.3{\pm}0.9years$ for the ICP patients. A retrospective analysis was performed of the complications, the frequency of subsequent surgical correction for velopharyngeal dysfunction (VPD), and speech outcomes. Results In both the SMCP and ICP patients, no cases of respiratory difficulty, bleeding, or wound disruption were noted. Delayed wound healing and fistula occurred in 18.9% and 5.7% of the SMCP patients and in 14% and 3.2% of the ICP patients, respectively. However, no statistically significant difference in either delayed wound healing or fistula occurrence was observed between the two groups. The rate of surgical correction for VPD in the SMCP group was higher than in the ICP group. In the subset of 26 SMCP patients and 62 ICP patients who underwent speech evaluation, the median speech score value was 58.8 in the SMCP group and 66 in the ICP group, which was a statistically significant difference. Conclusions SMCP and ICP were found to have similar complication rates, but SMCP had significantly worse speech outcomes.

  • Objective: This study is performed to investigate the trend of health care (HC) utilization among cleft lip and/or palate (CL/P) during 2007-2016 by using data from the Korean National Health Insurance Service (KNHIS). Methods: The KNHIS data were reorganized to count a specific patient only once for a specific year. Cleft type (cleft lip [CL], cleft palate [CP], and cleft lip and palate [CLP]), sex, and age at HC utilization were investigated. The study period was divided into the first half (2007-2011) and the last half (2012-2016). The utilization number and rate per 1,000 population were calculated for the total population and for new-born patients. Independent t-test and one-way analysis of variance were used for statistical analyses. Results: The total CL/P population (n = 48,707) comprised 19.2% CLP, 35.5% CL, and 45.3% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 0.066 in 2007 to 0.118 in 2016. The new-born patient population (n = 7,617) comprised 18.6% CLP, 30.4% CL, and 51.0% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 1.12 in 2007 to 1.74 in 2016. An examination of the utilization number and rate among new-born patients revealed CP exhibited a female-dominant pattern (all p < 0.01), while CL and CLP exhibited a male-dominant pattern (all p < 0.01). However, utilization number showed no difference by sex and cleft type between 2007-2011 and 2012-2016. Conclusions: These results might serve as a guideline for HC utilization among patients with CL/P.

  • Otitis media with effusion is known to be very common among children with cleft palate and is the common cause of acquired hearing loss in childhood. The purpose of the present study was to examine the anatomic variances, incidence and treatment of middle ear disease in children with cleft palate. In Korea, before 4-year-old age, the prevalence of otitis media was as high as 91.7%. Common treatments for otitis media were conservative or surgical treatment. The medical treatment options include the use of decongestants, antihistamines, antibiotics and mucolytics. Surgical treatment options include grommet insertion, myringotomy. Unlike the case for children without clefts, cleft patient has a higher incidence of recurrence, so surgical treatment between the age of 3 month and 6 month was recommended. The effect of palatoplasty on middle ear disease has remained controversial. Early and periodic evaluation on the symptomatic infection or significant of hearing loss was recommended.

  • Background: The present study aimed to determine whether laypeople and professionals rate the facial appearance of individuals with repaired complete unilateral or bilateral cleft lip and palate (UCLP, BCLP) similarly based on viewing full facial images. Methods: The study followed a cross-sectional analytical design where five young patients aged 10 to 14 years, who had completed all stages of their unilateral or bilateral cleft lip and palate treatment (bilateral: three, unilateral: two), were evaluated by two groups. The assessment was done by laypeople and 97 qualified professionals (33 orthodontists, 32 plastic surgeons, and 32 oral and maxillofacial surgeons). Professionals were not involved in any stage of the patients' treatment. Results: The facial appearance assessment of the professional groups on different facial aesthetics was significantly lower than that of laypeople, and they had higher perceived need for further treatment. On the other hand, laypeople had higher aesthetic ratings and lower perceived need for further treatment. Differences were also observed between the assessments of the professional groups. Participants who had lower aesthetic assessments of the repair tended to report a higher influence of cleft lip and palate on social activities and professional life. Conclusion: Differences in perception exist between healthcare professionals and laypeople. The discrepancies between the professional groups could be attributed to different treatment modalities and protocols.

  • Cleft lip and palate is one of the congenital anomalies which need comprehensive and multidisciplinary treatment plan because 1) oral cavity is an important organ with masticatory function as a start of digestive tract, 2) anatomic symmetry and balance is esthetically important in midfacial area, and 3) it is also important to prevent psycho-social problems by adequate restoration of normal facial appearance. There are many different protocols in the treatment of cleft lip and palate, but our department has adopted and modified the $Z{\"{u}}rich$ protocol, as published in the Journal of Korean Cleft Lip and Palate Association in 1998. The first challenge is feeding. Type of feeding aid ranges from simple obturators to active orthopedic appliances. In our department we use passive-type plate made up of soft and hard acrylic resin which permits normal maxillary growth. We use Millard's method to restore normal appearance and function of unilateral complete cleft lip. In consideration of both maxillary growth and phonetic problems, we first close soft palate at 18 months of age and delay the hard palate palatoplasty until 4 to 5 years of age. When soft palate is closed, posterior third of the hard palate is intentionally not denuded to allow normal maxillary growth. In hard palate palatoplasty the mucoperiosteum of affected site is not mobilized to permit residual growth of the maxilla. We have treated a patient with unilateral complete cleft lip and palate by Ajou protocol, which is a kind of modified $Z{\"{u}}rich$ protocol. It is as follows: Infantile orthopedics with passive-type plate such as Hotz plate, cheiloplasty with Millard's rotation-advancement flap, and two stage palatoplasty. It is followed by orthodontic treatment and secondary osteoplasty to augment cleft alveolus, orthognathic surgery, and finally rehabilitation with conventional prosthodontic treatment or implant installation. The result was good up to now, but we are later to investigate the final result with longitudinal follow-up study according to master plan by Ajou protocol.

  • After cleft lip repair, many patients suffer from nasolabial fistulas, asymmetrical nasal floor, or an indistinct nostril sill, as well as intraoral wound dehiscence and subsequent scar contracture of surgical wounds leading to vestibular stenosis. For successful primary nasolabial repair of complete cleft deformity of the primary palate, cleft surgeons need special care in reconstructing the sound nasal floor. Especially when the cleft gap is wide or when any type of nasoalveolar molding therapy was not performed, three-dimensional reconstruction of the nasal floor is critical for a balanced nasal shape. In this study, the author describes an effective method for reconstructing a double-layered nasal floor using two mucosal flaps from both sides of the fissured upper lip. This is a report of six patients with unilateral or bilateral complete cleft of the primary palate with a detailed description of the surgical technique and a literature review.
