When traditional flap techniques are not feasible, we apply flap prefabrication, which is more complicated and sophisticated but supplies large and thin flaps. There are some disadvantages to the technique that require improvement, such as venous congestion after flap transfer, which requires months for neoangiogenesis and necessitates a vascular carrier. Here, the author presents a new technique, called as 'microdissected prefabricated flap,' to successfully produce a safe, large, and thin flap. This technique is based on the microdissection of the perforators to the greatest extent possible, spreading them out into the subdermal level and using them as a carrier. The details and the application of this technique are presented and reported.

The coronal approach is a versatile surgical technique. This method becomes particulary useful for exposure and internal fixation of midfacial fractures and the harvest of calvarial bone graft to manage the complex facial bone fractures. The rectrospective clinical study on the use of this technique in 10 patients was performed. The result shows that this technique provides the excellent exposure of fractures site, the ability to reduce the fragment accurately and good cosmetic results in incision area. We discussed with literatures review that anatomy, technique, indications, and potential complications of the coronal approach.

Velopharyngeal Insufficiency(VPI); the failure of velum, the lateral wall and the posterior pharyngeal wall to separate the nasal cavity from pharyngeal cavity during speech, can be caused by congenital conditions include cleft palate, submucous cleft palate and congenital palatal insufficiency. Speech problems of VPI are characterized by hypernasality, nasal air emission, increased nasal air flow and decreased intelligibility. These speech problems of VPI can be treated with the surgical procedure, the application of temporary prosthesis and speech therapy. Biofeedback technique with Nasometer is a speech treatment method of VPI that commonly used as one component of a comprehensive procedure for improvement of speech in patients with VPI. In this article describes a case of VPI treated by biofeedback technique with Nasometer; which showed satisfactory result in nasalance and formant analysis after the speech therapy during 9 months.

Once a submasseteric space infection is diagnosed, the key to resolving the infection is via surgical intervention to evacuate the pus. Although it is possible and occasionally practical to drain the submasseteric space via an intraoral approach, an extraoral approach may sometimes be required. Surgeons have encountered complications such as facial nerve damage during extraoral incision and drainage procedures, and they have felt that extraoral dissection was very difficult. As such, an easier and simpler technique is needed. Our department recently modified various drainage techniques for submasseteric space abscesses. Damage to the marginal branch of the facial nerve did not occur, and this technique was very simple and rapid, such that a novice physician could perform this procedure. This modified technique was possible with trismus and under local anesthesia. After intraorally checking the position of the drain, the intraoral wound is closed with an absorbable suture and the drain is fixed to the extraoral skin. When a masseteric space infection is diagnosed, multiple space involvement is ruled out, and dependent drainage is required, this modified drainage technique can be useful.

Purpose: The purpose of this study was to evaluate the prognosis (clinical outcomes) of one-stage flapless implant surgery based on success and survival rate and marginal alveolar bone loss. Materials and Methods: Ninety dental implants were placed according flapless surgical procedure in forty-one patients at Hospital between April 2004 and May 2009. The mean age of the patients was 54, and the patients were comprised of 24 men and 17 women. Each patient was investigated radiographically and clinically being with average follow up 49.7 period. Result: Average healing period is 4.45 month (maxilla: 5.31 month, mandible: 3.20 month) after installation and survival rate is 95.7% in this period. The survival rate and success rate at 1 year after function (prosthodontics setting) are 92.4% and 88.0%. At final observation, the survival rate and success rate are 90.2% (maxilla: 89.1%, mandible: 92.9%) and 84.8% (maxilla: 82.8%, mandible: 89.3%). The mean residual alveolar bone resorption at 1-year after function and final observation are 0.8 mm and 1.07 mm. Conclusion: Our study suggest that if appropriate surgical technique with proper patients selection, flapless implants surgery is predictable simple and safety technique.

Purpose: This study was aimed at analysis of the changes in the condyle position in subjects with mandibular setback osteotomies Method: Twenty patients were evaluated retrospectively for their changes in the condyle position who underwent surgical mandibular setback using bilateral sagittal split osteotomies with a manual condyle repositioning technique and rigid fixation. The cephalometric and panoramic analysis was performed preoperatively, 1 week, 6 months, and 1 year postoperatively. And postoperative noise, temporomandibular joint pain, and mouth opening were clinically examined 2 months, 4 months, 6 months, 8 months, 10 months, and 12 months postoperatively. Result: The condyles rotated posteriorly and laterally immediately after surgery, and they returned to the preoperative position during follow-up period but it is not significant. The statistical analysis (Paired t-test) showed no significant effects in postsurgical stability. The changes in the condyle position didn't have a significant harmful influence on temporomandibular joint disorder. Conclusion: A careful surgical mandibular setback using manual condyle repositioning and fixation technique will move condyle minimally and that will decrease the relapse and temporomandibular joint disorder.

Fractures of the mandible occur with a greater frequency in the elderly. This study reports three cases of edentulous atrophic mandible fracture in elderly patients treated with open reduction technique. Three patients who presented with edentulous atrophic mandible fractures underwent surgical management using open reduction and internal fixation. After treatment, clinical evaluations and postoperative complications were examined with postoperative x-ray. Patients were followed with clinical and radiographic examinations. In the postoperative clinical evaluation, two male patients healed well, but one female patient complained of pain and swelling. In radiographic examinations, no union delay or lack of fusion was observed in the edentulous area. Open reduction technique is a viable treatment option for the edentulous atrophic mandible fractures in geriatric patients.

Cleft lip is one of the most common congenital deformities in craniofacial region. Despite the many reports on the outcome of various surgical techniques from individual medical centers, the evaluation of the outcome is based on the subjective observation because of lack of the objective evaluation system. Therefore, a new technique of objective and scientific evaluation for the nasal deformity of secondary cleft lip and nose deformity is critical to improve the management of the cleft patients including the decision of optimal age of operation and surgical technique as veil as evaluation of the outcome. In this study, a new method was proposed to evaluate the nasal deformity using nostril angle, distance, and area of patient images. The images were also evaluated by three expert plastic surgeons, and put into scale of 5 percentile. Measurement results were compared between the each category and the surgeon's evaluation, and coefficients of each category were statistically tested. As a result, The normalized overlap area of right and left nostrils and distance ratio between two centers of nostrils showed high coefficient with evaluations of plastic surgeons.

A sexually intact female Alaskan Malamute, 5-year-old weighing 25.2 kg presented to the Hangang Animal Hospital, following hit-by-car. On initial presentation, the dog had severe salivation and the right canine tooth luxation. Radiographs revealed fractures of the right rostral hemimandible with the right canine tooth luxation and symphyseal separation. Surgical repair of fractures was performed by use of an interdental wiring technique and external fixation technique that included pins, an acrylic connecting bar, and polymethyl methacrylate bone cement. Post-operative radiographs revealed that bridging callus was well formed over cortices of the fracture area. Pins and an acrylic connecting bar were removed 7 weeks post-operatively. The dog exhibited evidence of normal mastication.
