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.

Thyroglossal duct cyst is a congenital anomaly generally appearing as an asymptomatic midline neck mass. Generally, the duct cyst is benign, but 1 percent of cases may be malignant. These present the same histologic types as thyroid carcinomas. The most common pathologic type is papillary carcinoma. Regional lymph node metastasis of papillary carcinomas in thyroglossal cyst occurs in 7.7 percent of cases. Prognosis of papillary carcinoma is excellent. The treatment has been quite variable, but the most common initial treatment is Sistrunk's operation. Adequate excision of cyst and its tract including the mid-portion of the hyoid bone is the treatment of choice. We experienced two cases of papillary carcinoma arising in thyroglossal duct cyst between 1986 and 2002.

The aim of this report was to present a rare case of a tracheotomy site recurrence after operation and post-operative radiotherapy in head and neck squamous cell carcinoma patient. Tracheotomy site recurrence other than subglottic cancer is very rare in head and neck cancer patient. The granulation tissue around tracheotomy was a fertile "soil" for tumor cell implantation. Midline mucosal sparing block which was used to decreased acute toxicity during post-operative radiotherapy could be facilitating the tumor cell implantation. The head and neck surgeon should try every effort to reduce contamination of cancer cells during operation and consider the entire operative field should be included in post-operative radiation portals.

Osteoma is benign tumor composed of mature compact or cancellous bone. Generally it is classified as periosteal(or peripheral) osteoma and endosteal(or central) osteoma by its origin. Clinically, periosteal osteoma on forehead is usually asymptomatic. From March 2002 to February 2005, We experienced 20 patients(23 cases) of histologically confirmed frontal osteoma. 20 patients are classified as sex, age, the number of osteoma, size, location and shape. Out of 20 patients, 16 were female and 4 were male in sex and mean age was 46. 18 patients have only one lesion but one patient has two lesions and another patient has three lesions. The size of osteoma varied from $7{\times}5{\times}3mm$ to $16{\times}14{\times}6mm$ and mean size is $12{\times}10{\times}5mm$. All osteomas were located at midline of forehead and shape of attachment was all sessile type. Surgical excision was superficial ostectomy through direct cutaneous incision or endoscopic approach. we obtained satisfactory result without specific complication.

Varying degrees of complications can occur after hyaluronic acid filler injections. Tissue necrosis due to interruption of the vascular supply is an early complication that can be severe. If the site of tissue necrosis due to the filler injection is the forehead, successfully reconstructing the region without distorting the key landmarks is challenging. We describe the case of a 50-year-old man who experienced widespread forehead skin necrosis after hyaluronic acid filler injection in the glabellar area. We successfully covered the forehead area with a $3{\times}4-cm^2$ midline necrotic tissue using the modified double-opposing rotation-advancement flap method. Although modified double-opposing rotation-advancement flap closure has the disadvantage of leaving a longer scar compared to conventional double-opposing rotation-advancement flap closure, the additional incision line made along the superior border of the eyebrow aids in camouflaging the scar and decreases eyebrow distortion. Therefore, it is believed that the modified double-opposing rotation-advancement flap technique is an excellent tool for providing adequate soft tissue coverage and minimal free margin distortion when reconstructing widespread skin necrosis in the central mid-lower forehead that can occur after filler injection in the glabellar area.

The aim of the present study is to investigate the flow interference between two adjacent undulating fish-like body, and its effect on the undulating propulsion. For this purpose, unsteady two dimensional incompressible flow calculations were conducted using an unstructured mesh flow solver, coupled with an overset mesh technique. To deal with mesh deformation due to fish locomotion, spring analogy is utilized. The fish body used in the simulation is constructed from the NACA0012 airfoil. The study indicates that the propulsion of undulating fish is proportional to frequency and wavelength of the midline oscillation when there is no adjacent fish. It also reveals that average thrust was increased when the vortex shedding from the tail was conserved well and pressure difference between upper and lower sides of the fish was magnified due to flow interference. From this study, which relative position and phase difference of locomotion between two fishes can generate maximum thrust was known among six different cases.

돌발 반두통은 일측성이고 짧은 시간동안 심한 통증이 있는 경우이며, 대부분 두개의 자율신경계 증상을 동반한다. 이는 군발 두통의 통증, 동반 증상과 징후와 비슷하지만, 돌발 반두통은 지속시간이 더 짧고, 더 빈번하며, 인도메싸신에 잘 반응한다. 1992년에 Sjaastad에 의해 돌발 반두통이 반대쪽으로도 이동한다고 처음 보고하였으며, 문헌에는 단지 4례가 보고되었다. 4례 중 3례는 자율신경계 증상을 동반하지 않았으며, 1례만 자율신경계 증상 동반을 하였다. 저자는 10세 소아에서 자율신경계 증상을 동반한 전형적인 증상과 인도메싸신으로 치료된 양측 돌발 반두통 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Megalencephaly-capillary malformation-polymicrogyria syndrome (MCAP), previously known as macrocephaly-cutis marmorata telangiectatica congenita and macrocephaly-capillary malformation syndrome, is a rare multiple-malformation syndrome that is characterized by progressive megalencephaly, capillary malformations of the midline face and body, or distal limb anomalies such as syndactyly. Herein, we report a female infant case that satisfies the recently proposed criteria of MCAP and describe the distinctive neuroradiological and morphological features. We have also reviewed recently published reports and the diagnostic criteria proposed by various authors in order to facilitate the clinical diagnosis of these children in pediatric neurology clinics.

The author has studied mandibular opening and closing movement patterns using mandibular kinesiograph in order to make basic data that is necessary to diagnose the mandibular movement function. The 83 normal subjects, who were students of the school of dentistry. Kyunpook National University and Daegu Junior Health College, were selected according to sampling criteria. The results were as follow : In the sagittal plan, crossover pattern had the highest incidence in male (72.7%) and female(76.8%). There was no significant defference of distribution of habitual closing movement patterns between male and female.(p>0.05). There were difference between each patterns.(p<0.01) In the frontal plane, there was no difference of distribution of male's opening and closing movement patterns between habitual and maximum velocity (p<0.05),but difference between each subjects. (p<0.05) In the frontal plane, there was no difference of distribution of habitual opening and closing movement patterns between male and female.(p<0.05) In the frontal plane, the average number of habitual opening and closing pathways cross the midline was greater than that of maximum velocity.(p<0.05) The average of the maximum mandibular movemet velocity of male was greater than female in opening and contact(p<0.01) and there was no difference between male and female in closing.(p>0.05)

Aucubin, the natural product, which is isolated from Aucuba japonica, has a variety of pharmacological effects such as liver-protective function, inhibition of liver RNA and protein biosynthesis, hypotensive activity and antimicrobial effect, etc. This study was performed to investigate the effects of iridoid compounds on wound healing. The author prepared 0.1% aucubin solution and 0.1% aucubin ointment as an active form, aucubigenin to which aucubin was converted by ${\beta}$-glucosidase. Artificial surgical wound was made on either 1cm lateral side of the dorsal midline along the axis of spine of Sprague-Dawley rats under sterile technique. Application of 0.1% aucubin solution or 0.1% aucubin ointment to surgical wound was done daily. Light microscopic examination was performed on the postsurgical 3 days, 5 days, and 9 days. The 0.1% aucubin solution group epithelialized earlier than the control group and the fibrosis of granulation tissue of both aucubin groups were more prominent than the control group. Collectively, this study suggests the possibility of aucubin as a topical agent. Further research should be performed on the mechanism of aucubin on wound healing and proper formulation for effective topical agents.
