The velopharyngeal dysfunction usually occurs in patients with previous operation of the cleft palate or with submucosal cleft palate. In case of velopharyngeal dysfunction without cleft palate, no study has been made when it comes to operative method and postoperative results. Here, we would like to present the operative methods and the postoperative results with the cases we've experienced. This study is based on seven cases of velopharyngeal dysfunction without cleft palate from 1999 to 2004. Analysis of age, sex, etiology, operative methods, satisfaction rate and speech evaluation was done. The patients were 3 males and 4 females, with an age ranged from 10 to 28 at the time of surgery. The follow-up period was more than six months. One case had bifid uvula, another had atypical anomaly in palate, and five cases had no anatomical abnormality. The palatal lengthening was done on one patient, the levator muscle repositioning on another patient and to the rest of them, the superiorly based posterior pharyngeal flap was done. It was difficult to determine the etiology of the velopharyngeal dysfunction without cleft palate. The speech improvement and the satisfaction rate of the patients and parents were diverse. Although the authors had a problem with statistical analysis between the operative age and the speech improvement, it was reasonable to perform a surgical operation because postoperative speech improvement was observed in most cases regardless of age. There is little statistical correlation, but significantly higher outcomes were observed in palatal lengthening and levator muscle repositioning than in pharyngeal flap.

In order to solve the problem of repositioning the old hader bar attachment and to restore the non-esthetic facial profile and improper occlusion of the edentulous patient due to inadequate jaw relation, determination of vertical dimension of occlusion and tooth arrangement were performed similar to the natural teeth before the teeth loss. In addition to improving the esthetics by restoring the inadequate facial appearance, the composite resin was used to maximize the patient's secondary esthetic satisfaction with the denture.

It is difficult to perform orthodontic treatment for cleft lip and palate patient. Although there are many orthodontic appliances to expand narrowed maxillary arch, results are rarely successful and the possibility of relapse is increased due to severe scars. Self-ligating bracket, recently used in orthodontic treatment, suggests solution of crowding by expansion of dental arches. Light and continuous force could apply for orthodontic movement due to characteristic low friction of self ligating bracket, which gives expansion force until dentition reaches its new equilibrium position and it can be expressed as spontaneous lateral expansion with heavy labial tension. This kind of expansion force is thought to be a possibility of expanding the constricted maxillary arch of cleft lip and palate patient. Repositioning of the maxilla by Le Fort I osteotomy in case of severe maxillary deficiency, increases the possibility of relapse because of limitation in anterior movement and adaptation of soft tissue. In these cases, distraction osteogenesis(DO) can be applied for stable result. We report a case of cleft lip and palate patient with narrowed maxillary arch and maxillary deficiency using self ligating bracket and DO.

Objective: This clinical study was performed with a female patient to evaluate the effects of combined Eastern-Western medicine treatment on benign paroxysmal positional vertigo after acute vestibular neuritis.Method: We used acupuncture, herbal medication, Western medication, fluid therapy, and the canalith repositioning maneuver to treat a female patient suffering from dizzy spells. The vertigo scale was checked to assess any improvement in symptoms.Results: The patient had originally recovered from acute vestibular neuritis, but after the first discharge, she came down with benign paroxysmal positional vertigo and had to be rehospitalized. She eventually got better, however, and her score on the vertigo scale improved.Conclusion: This study demonstrates that combined Eastern-Western medicine treatment may be an effective option for treating benign paroxysmal positional vertigo after acute vestibular neuritis, despite the difficulty of the treatment in this case.

Posterior canal benign paroxysmal positional vertigo (PCBPPV) is the most common disease among patients who visited the st. Carollo hospital dizziness center with the head suddenly feeling rolling or rotational dizziness caused by head and body movements. Most patients showed improvements in symptoms after a single treatment. On the other hand, there are more causes requiring multiple treatments. This study examined the factors affecting the canalithiasis repositioning maneuver for symptom recovery of dizziness, which is posterior BPPV. Dizziness patients who visited the dizziness center of PCBPPV were classified. From March 2008 to November 2010, the cure rate of 165 posterior BPPVs patients was investigated. The success rate after the first, second, third, and further treatments was 57.6%, 17.6%, 10.3%, and 14.5%, respectively. The factors affecting treatment of PCBPPVs included traumatic, medical disease, cerebral infarction, small vessel disease, vestbro basilar artery insufficiency (VBI), cerebrovascular disease, brain disease, and vestibuloplasty (P<0.05). Vomiting, nausea, and syncope can be treated easily by considering the factors affecting these treatments. If the related diseases are combined with the treatment of the canalithiasis repositioning maneuver for symptom recovery of dizziness, the results will show an improvement in daily life that is free from painful dizziness.

Background: Along with the advances in technology of three-dimensional (3D) printer, it became a possible to make more precise patient-specific 3D model in the various fields including oral and maxillofacial surgery. When creating 3D models of the mandible and maxilla, it is easier to make a single unit with a fused temporomandibular joint, though this results in poor operability of the model. However, while models created with a separate mandible and maxilla have operability, it can be difficult to fully restore the position of the condylar after simulation. The purpose of this study is to introduce and asses the novel condylar repositioning method in 3D model preoperational simulation. Methods: Our novel condylar repositioning method is simple to apply two irregularities in 3D models. Three oral surgeons measured and evaluated one linear distance and two angles in 3D models. Results: This study included two patients who underwent sagittal split ramus osteotomy (SSRO) and two benign tumor patients who underwent segmental mandibulectomy and immediate reconstruction. For each SSRO case, the mandibular condyles were designed to be convex and the glenoid cavities were designed to be concave. For the benign tumor cases, the margins on the resection side, including the joint portions, were designed to be convex, and the resection margin was designed to be concave. The distance from the mandibular ramus to the tip of the maxillary canine, the angle created by joining the inferior edge of the orbit to the tip of the maxillary canine and the ramus, the angle created by the lines from the base of the mentum to the endpoint of the condyle, and the angle between the most lateral point of the condyle and the most medial point of the condyle were measured before and after simulations. Near-complete matches were observed for all items measured before and after model simulations of surgery in all jaw deformity and reconstruction cases. Conclusions: We demonstrated that 3D models manufactured using our method can be applied to simulations and fully restore the position of the condyle without the need for special devices.

Purpose: The orbital fat buldging may cause irregular contour of lower eyelid, which is not youthful appearance. The conventional method of fat excision may cause the eyeball to move backward and downward, making enopthalmia is inevitable. The transcutaneous approach to reach the orbital septum can increase the risks of scleral show resulting from scarification at the level of the septum orbicularis junction and damaging the vertical motor branches of the preseptal orbicularis oculi muscle of the lower eyelid. Method: From July 2007 to March 2008, total of 21 patients underwent transconjunctival capsulopapebral fascia fixation procedure. In 8 patients, the herniated fat pad of the lower eyelid was relocated back into the orbit without external skin excision using capsulopalpebral fascia fixation. But in 13 patients, excision of redundant skin of the lower eyelid was performed using pinching technique, not involving orbicularis oculi muslce. In 5 patients, lateral canthotomy was done bilaterally for good visual field. In 6 patients, lateral canthopexy was also combined to correct loosening of lower eyelid. Results: Most of the patients were satisfied after at least 5 months of follow up. No patient showed scleral show. But 2 patients complained of undercorrection slightly, without secondary operation in 1 patient and re - capsulopalpebral fascia fixtation through transconjunctival approach in another patient. Conclusion: Orbital fat repositioning using transconjunctival capsulopalpebral fascia fixation is a good procedure to show youthful appearance without increasing the risk of scleral show and also showed fast recovery compared to the conventional transcutaneous approach.

Objective: We report a case of a 73-year-old Korean male with vertigo and nausea, both of which were brought about by head repositioning. The condition was diagnosed as benign paroxysmal positional vertigo (BPPV).Method: The patient was treated with acupuncture, electroacupuncture, cupping, transcutaneous electrical nerve stimulation (TENS), and herbal medicine (Bosimsahwacheonggan-tang [補心瀉火淸肝湯]). We conducted the vertigo symptoms scale (VSS) and the dizziness handicap inventory (DHI) to evaluate the degree of the patient’s symptoms.Results: Vertigo and nausea started to improve after the administration of Bosimsahwacheonggan-tang, but although the patient took the anti-vertigo medication and a tranquilizer after the symptoms became aggravated, no prominent improvements could be observed.Conclusion: These results suggest that traditional Korean medical treatment may be effective in treating peripheral vertigo due to BPPV.

Purpose: Retro-orbicularis oculi fat (ROOF) and preseptal fat pad (PSF) are deep fat structures of frontal and supraorbital area, that encounter galeal fat pad (GFP). If galeal wall is weakened by aging process, GFP loses its anchoring structure, moved downward pushing ROOF and PSF. This especially occur in lateral brow area. As a result of drooping, eyebrow affects the eyelid covering PSF as a sac descended to a lateral hooding and ptotic eyelid simultaneously. Consequently, in the case of lateral hooding and brow ptosis, besides the skin, deep fat structures (ROOF and PSF) should be corrected as well. Methods: ROOF-PSF repositioning technique in subbrow resection were performed. 21 cases of patients from April, 2007 to January, 2008. Before surgery, all patients were examined carefully to evaluate the degrees of dermatochalasia, drooping of the eyebrow, marginal reflex distance 1 (MRD1), eyelid crease height. Surgery was performed under local anesthesia, then excised the drooped eyelid skin by lateral subbrow resection, removed proper amount of ROOF, repositioned ROOF-PSF at the supraorbital rim, and fix it on periosteum. During follow up periods, the patients were surveyed of the satisfaction of surgery, and postoperative MRD1 was evaluated. Results: One patient had a hematoma on left eyebrow, and another one patient had a numbness on left forehead for two months. Except for these two patients, all patients had good results without any significant complications. The mean follow up period was about 5 months, and the position of lateral eyebrow maintained above the supraorbital rim in all cases. Postoperatively, MRD1 increased by 0.8 mm in 5-months mean follow up period. Conclusion: In patient with lateral brow ptosis and lateral hooding, the ROOF-PSF repositioning technique in sub-brow resection could be a good operative option.

Objectives: Transpositioning of the inferior alveolar nerve to prevent injury in lower jaw has been advocated for orthognathic, pre-prosthetic and for implant placement procedures. However, the concept of infra-orbital nerve repositioning in cases of mid-face fractures remains unexplored. The infraorbital nerve may be involved in trauma to the zygomatic complex which often results in sensory disturbance of the area innervated by it. Ten patients with infraorbital nerve entrapment were treated in similar way at our maxillofacial surgery centre. Materials and Methods: In this article we are reporting three cases of zygomatico-maxillary complex fracture in which intra-operative repositioning of infra-orbital nerve into the orbital floor was done. This was done to release the nerve from fractured segments and to reduce the postoperative neural complications, to gain better access to fracture site and ease in plate fixation. This procedure also decompresses the nerve which releases it off the soft tissue entrapment caused due to trauma and the organized clot at the fractured site. Results: There was no evidence of sensory disturbance during their three month follow-up in any of the patient. Conclusion: Infraorbital nerve transposition is very effective in preventing paresthesia in patients which fracture line involving the infraorbital nerve.
