  • Patients with cleft lip and palate usually show up maxillary hypoplasia. In these cases, a large amount of maxillary advancement is often needed to correct the severe deformity, but local soft-tissue scars around the maxilla restrict maxillary advancement and increase the relapse rate. Maxillary distraction osteogenesis is an effective method for facial and occlusal improvement in these patients. By gradually lengthening both the bones and the soft tissues, distracted midface can greatly increase postoperative stability and decrease the relapse rate. However, the maxillary extraoral appliances of the early days used were esthetically unappealing as well as difficult for the patient to manage. Recently, more inconspicuous intraoral distraction appliances have been developed and used with success. We acquired favorable result in two patients(bilateral 1 patient and unilateral 1 patient) with severe maxillary hypoplasia secondary to complete cleft lip and palate were treated with midface distraction using internal distractor (Zurich Pediatric Maxillary Distractor, KLS Martin, Tuttlingen, Germany). So, we report our experience with literatures.

  • Two dogs were presented with a history of anorexia, respiratory distress, or epistaxis. On physical examination, the dogs showed difficulty breathing and open-mouth breathing and large masses were found on the hard palate and soft palate. Cardiac arrest happened in case 2 and the dog was stabilized with cardiopulmonary resuscitation and oxygen therapy. Computed tomography demonstrated that the mass occupied the oropharynx, intrapharyngeal ostium, and laryngopharynx including the hard palate and soft palate in case 1. Palliative surgery was decided to improve swallowing and breathing with owner's consent in two dogs. Buccal mucosal flaps were performed for reconstruction of defects using rotational and single-pedicle advancement flaps and bilateral 90 degree transposition flaps in cases 1 and 2, respectively. Histopathology results described the oral masses as amelanotic melanoma in two dogs. The owners reported that there was normal swallowing and breathing at 7 days postoperatively in two dogs. In case 1, recurrent tumor was identified caudal to the hard palate 4 weeks after surgery. The owner did not allow further treatment and the dog became lost to follow-up at 2 months postoperatively. In case 2, there was no clinical or radiographic evidence of a local recurrence or distant metastasis at 3 weeks after surgery. The owner informed that the dog died suddenly with no signs of anything particularly wrong at 7 weeks after surgery.

  • For the treatment of cleft palate patients, orthognathic surgery has been used by standard protocol. Predictable results have been achieved with standard techniques in slight to moderate maxillary hypoplasia. However, limited advancement and high relapse rate was reported in severe cases. The purpose of the present study was to review the clinical results of distraction osteogenesis in the patients with cleft lip and palate. Distraction osteogenesis has improved results in these patients by allowing soft tissue relaxation and gradual bone generation. Therefore, greater movement of the craniofacial skeleton is possible in severe cases of maxillary retrusion with lower relapse rates. In conclusion, distraction osteogenesis for the advancement of hypoplastic maxilla of cleft patients has shown successful treatment method.

  • Generally, an adult cleft lip or/and palate patient shows some amount of maxillary deficiency due to limitation of bony growth caused by heavy scars resulted from previous operations such as a cheiloplasty and/or a palatoplasty at an early child age. To solve the problem, advancement of the maxilla is usually required during orthognathic surgery. However, severe tensional force resulted from heavy scars on the palate and/or the lip, as well as the bony defect at the cleft area limited sufficient advancement of the maxillary segment and finally caused relapse of the reposed maxilla. Therefore, distraction osteogenesis of the maxilla was introduced for the successful maxillary advancement inthose kinds of patients. As both hard and soft tissues can be simultaneously and gradually extended with this technique, tensional force caused by heavy scars opposed to forward movement of the maxilla can be reduced to an extent not to develop severe relapse of the advanced maxilla. Since distraction osteogenesis of the maxilla was applied as one of standard protocols for the treatment of the patients with severe maxillary hypoplasia dueto cleft lip and/or palate, the devices for the distraction was improved to control the vectors of distraction with better and more stable. We have treated a 23-year-old male cleft patient with a severe maxillary hypoplasia using a newly developed a maxillary distraction device and a RP model for a pre-operative simulation surgery. As a result, we could successfully move the maxilla as we designed pre-operatively and also reduce much of operation time. Therefore, we report of the case to share our experience with colleagues.

  • Objective : The objective of this study was to compare the surgical techniques for the correction of congenital cleft 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.

  • Purpose: Torus palatinus is a bony prominence at the middle of the hard palate. The size varies from barely discernible to very large, from flat to lobular. This oral exostosis is not a disease or a sign of disease, but if large, may be a problem. So, we present the clinical and histopathologic features and applied therapy and provide a comprehensive review of the rare case of the symptomatic exostoses. Methods: A 37-year-old woman had slowly growing exophytic nodular mass of the bone that arises the midline suture of the hard palate. The patient was concerned about discomfort associated with movement of her tongue and about frequent irritation of the palatal mucosa during mastification of the hard food. The patient had a large, unilobulated torus palatinus. It extended from the area adjacent to the canine to a point beyond the junction with the soft palate. The mass was oblong in shape, measuring about 3 cm long, 2 cm wide, and 0.8 cm in height. Results: Before surgical intervention a CT was obtained for the sake of estimating the thickness of the bone between the exostoses and the maxillary antrum and floor of the nose. The surgical procedure was performed with the patient under general anesthesia. Removal of the exostosis was performed after midline mucoperiosteal incision with osteotome and diamond burr. Histologic finding revealed decalcified dense bony tissue, the presence of lacunae, and normal osteocytes. Conclusion: Surgical removal is recommended when one or more of the following condition exist: interference with the construction of prosthesis, interference with oral function, irritation or pathology of the overlying tissue, inability of the patient to maintain proper oral hygiene, and fear of malignancy or other psychologic trauma. We report a rare case of the torus arising in hard palate with symptoms.

  • Background No consensus exists on the optimal treatment protocol for orofacial clefts or the optimal timing of cleft palate closure. This study investigated factors influencing speech outcomes after two-stage palate repair in adults with a non-syndromal complete unilateral cleft lip and palate (UCLP). Methods This was a retrospective analysis of adult patients with a UCLP who underwent two-stage palate closure and were treated at our tertiary cleft centre. Patients ${\geq}17$ years of age were invited for a final speech assessment. Their medical history was obtained from their medical files, and speech outcomes were assessed by a speech pathologist during the follow-up consultation. Results Forty-eight patients were included in the analysis, with a mean age of 21 years (standard deviation, 3.4 years). Their mean age at the time of hard and soft palate closure was 3 years and 8.0 months, respectively. In 40% of the patients, a pharyngoplasty was performed. On a 5-point intelligibility scale, 84.4% received a score of 1 or 2; meaning that their speech was intelligible. We observed a significant correlation between intelligibility scores and the incidence of articulation errors (P<0.001). In total, 36% showed mild to moderate hypernasality during the speech assessment, and 11%-17% of the patients exhibited increased nasalance scores, assessed through nasometry. Conclusions The present study describes long-term speech outcomes after two-stage palatoplasty with hard palate closure at a mean age of 3 years old. We observed moderate long-term intelligibility scores, a relatively high incidence of persistent hypernasality, and a high pharyngoplasty incidence.

  • A 11-month-old infancy was referred for treatment of cleft palate. The patient's congenital deformities had included oronasal fistula on the soft palate and bifid uvula. Furrow double-opposing Z-plasty was performed under general anesthesia. However, postoperative bleeding developed at ward. Despite the pressure of operative wound, venous oozing continued and hemoglobin concentration and RBC were decreased (Hb: 5.5g/dL, RBC: $1.98{\times}10^6/mm^3$). The patient was pale and confused and transferred to Surgical Intensive Care Unit(SICU) We could not keep the peripheral venous line and there was a high risk of hypovolemic shock. Emergency transfusion was performed through the central femoral venous line and emergency operation for bleeding control was carried out. We explored the operation site and found bleeding point from the posterior pharyngeal wall. Electrocoagulation and surgicel packing were carried out and bleeding was stopped.

  • Severe maxilla1y deficiency can be caused by cleft lip and palate(CLP), other craniofacial deformities, atrophy in the edentulous maxilla, and trauma. Patients with maxillary deficiency present a difficult treatment challenge. Traditionally, this skeletal deformity has been treated by Le Fort osteotomy, skeletal repositioning, and fixation with mini-plates and screws. The drawbacks of this method include a limited amount of anterior maxillary advancement often requiring simultaneous mandibular setback, the inability to create new bone, and minimal soft tissue adaptation to the new position, all of which increase the potential of relapse in case of large advancement. The alternative method of maxillary distraction osteogenesis offers promising results for successfully treatment of these patients while potentially minimizing the risk of relapse.

  • The purpose of this study was to determine whether any similarity existed in craniofacial morphology between parents and offspring in cleft lip with or without cleft palate. Thirty three measurements of the various regions of cranium and face were obtained from lateral cephalometric radiograms in 28 families comprising 28 fathers, 28 mothers and 28 cleft patients. The measurements of cleft patients were compared with those of their fathers, mothers and midparents. The obtained results were as follows: 1. There were similar measurements between the cleft patients and their fathers; rama1 height(Ar-Go), mandibular angle(∠MP-RP). 2. There were similar measurements between the cleft patients and their mothers; cranial base angle(∠NSBa), relation of maxilla to the cranial base(∠SNA), relation of maxilla to the cranial base(soft tissue:∠BaN'Sn), angle of inferior border of mandible(∠SNL-MP) and convexity of nose apex(soft tissue:∠N'PmPog'). 3. There were similar measurements between the cleft patients and their midparents; ramal height (Ar-Go), cranial base angle( ∠NSBa), relation of maxilla to the cranial base(soft tissue: ∠BaN'Sn), Y axis angle(∠NSGn) and mandibular angle(∠MP-RP). 4. There was no similar measurements between the cleft patients and their fathers and mothers simultaneously.
