Significant low knowledge and poor attitudes on complementary feeding undermine the practices. This study was a cluster randomized controlled trial in which 284 study participants were assigned into two groups. One intervention group and a control group in a ratio of 1:1. Nutrition education on complementary feeding was carried out among the caregivers in the intervention group but the caregivers in the control group were not educated. To determine complementary feeding knowledge and attitudes, data was collected from caregiver at baseline, midline and at endline using researcher-administered questionnaires. Quantitative data were analyzed using SPSS version 22.0. From the analysis, there was a significant difference in complementary feeding knowledge of the caregivers after the intervention. The baseline difference was -0.06, the midline difference was 3.85 the endline difference was 4.00 and the DID of the baseline and endline was 4.06 which was significant at p=0.001. There was a significant difference in the attitude of the caregivers towards complementary feeding at baseline (-0.14), midline (2.09), endline (3.82) and the DID of baseline and endline was 3.96 which was significant at p=0.001. The intervention improved the caregivers' knowledge on complementary feeding and it improved the attitudes of the caregivers towards adequate complementary feeding.

Purpose: Congenital sinus of the upper lip is extremely rare and only 3 cases have been reported domestically. We report a case of congenital sinus of midline upper lip, which was found in an adolescent patient. Methods: A 14-year-old girl presented with a small pit on midline of the upper lip, which was visible at birth. The patient had never been treated for the congenital sinus because it was asymptomatic. Surgical excision under local anesthesia was performed. Results: The sinus had a tract extending into 5 mm posteroinferior and had not penetrated the oral cavity. Histological examination showed a fistulous tract lined by keratinized squamous epithelium. After complete excision, there was no recurrence and we obtained a satisfactory cosmetic result. Conclusion: Congenital sinus of the midline upper lip is extremely rare. This is a special case that is reported because it did not cause symptoms for the patient until she reached adolescence.

Seven patients having midline granuloma received local irradiation from March 1983 to June 1986. Clinically, all of the 7 patients had pansinusitis with necrotic destruction of the involved sites and one case revealed colonic lesion. Each of the patients received a tumor dose of $4,000\~5,000 cGy/5\~6$ wks to the upper aerodigestive tract using a 6-MV linear accelerator. Complete and partial remission occured in 3 patients each, and in one case, the disease progressed despite of the irradiation.

Cystic glioblastoma multiforme (GBM) is a rare disease. Its exact prevalence has not yet been reported. Also, the mechanism of cyst formation remains to be elucidated. We report a case of GBM with a large peripheral cyst. A 43-year-old woman visited our clinic with a 3-month history of severe headache, memory impairment and general weakness. T1-weighted gadolinium-enhanced magnetic resonance (MR) image revealed a midline enhanced solid mass and bilateral symmetric banana-shaped peripheral cysts. A centrally enhanced mass was measured $2{\times}4$ cm in size and both mass and cysts as $7{\times}7$ cm. Both the frontal lobe and the frontal horn were severely compressed inferiorly and posteriorly. We resected a midline solid tumor and cysts via the bilateral interhemispheric transcortical approach. Histopathologic examination revealed GBM. The patient was subsequently treated with fractionated conventional brain radiation therapy, followed by temozolomide chemotherapy. Eighteen months later, there was no tumor recurrence and no neurological deficits were noted. Our patient showed no tumor recurrence and a long survival at a long follow-up.

In lower abdominal flap representing transverse rectus abdominis musculocutaneous (TRAM) flap or deep inferior epigastric perforator (DIEP) flap, superficial inferior epigastric vein (SIEV) exists as superficial and independent venous system from deep system. The superficial venous drainage is dominant despite a dominant deep arterial supply in anterior abdominal wall. As TRAM or DIEP flaps began to be widely used for breast reconstruction, venous congestion issue has been arisen. Many clinical series in regard to venous congestion despite patent microvascular anastomosis site were reported. Venous congestion could be divided in two conditions by the area of venous congestion and each condition is from different anatomical causes. First, if venous congestion was shown in whole flap, it is due to the connection between SIEV and vena comitantes of DIEP. Second, if venous congestion is limited in above midline (Hartrampf zone II), it is due to problem in venous midline crossover. In this article, the authors reviewed the role of SIEV in lower abdominal flap based on the various anatomic and clinical studies. The contents are mainly categorized into four main issues; basic anatomy of SIEV, the two cause of venous congestion, connection between SIEV and vena comitantes of DIEP, and midline crossover of SIEV.

Background and Objectives : Arytenoid adduction procedure is one of the main surgical options addressed for the correction of glottal incompetence in patients with unilateral vocal cord paralysis. Traditionally, a midline approach is used for identifying and suturing around the muscular process, which often needs over-traction of the thyroid cartilage and results in patient's discomfort as well as surgeon's distress. The authors investigated the advantage of a modified procedure, lateral approach, in which the arytenoid cartilage is exposed through the space between strap muscles and sternocleidomastoid muscle. Materials and Methods : Retrospective chart review was performed for 66 patients who received arytenoid adduction surgery at Samsung Medical Center, between the year 1997 and 2014. Operation time, types of anesthesia, voice outcomes and complications were compared between the midline (n=22) and the lateral (n=44) approach group. Results : Operation time was shorter in the lateral approach group ($125{\pm}24min$) than in the midline group ($144{\pm}24min$). Arytenoid adduction was proceeded under local anesthesia in 66% (n=29/44) and 14% (n=3/22) of patients with lateral and midline approach group, respectively. Voice outcomes and complication rates were comparable between the two groups. Injection laryngoplasty in conjunction with arytenoid adduction resulted in more favorable voice outcomes. Conclusion : A lateral approach for the arytenoid adduction procedure showed comparable voice outcomes and similar complication rates with those of a midline approach. However, lateral approach provided less discomfort to the patients and less distress to a surgeon, and therefore, shorter operation time was needed and local anesthesia could be more frequently applied for this modified procedure.

This study was performed to investigate the effect of mandibular midline shift and difference of mandibular height between both sides on the electromyo- graphic(EMG) activity of the masticatory muscles on clenching or gum chewing movement. For this study, 105 patients with temporomandibular disorders(TMD) were selected and panoramic radiograph were taken. Amount and side of the midline shift and height of the mandible from antegonial notch to the top of the condylar head were measured on panoramic view. $BioEMG^{(R)}$ (Bioresearch Inc., Milwaukee, USA) was used for recording of EMG activity(${\mu}V$) of the anterior temporalis and the superficial masseter on clenching or gum chewing movement. EMG activity on clenching during 533msec period were measured for activity of the starting point and the one second-after activity as the early EMG and the maximum EMG, respectively. EMG activity on gum chewing movement were measured for activity of the first and the second chewing stroke. The data collected were analysed by SPSS windows program, and the results of this study were as follows : 1. Height of the mandible was 8.06cm on right side and 8.03cm on left side, and showed no difference by age, but significantly differed by sex with higher in male subjects. 2. Mean value of the midline shift was 0.1mm with range of 0~5mm on both sides. The amount and side of the midline shift did not related with height difference of the mandible and/or the EMG activity of the masticatory muscles on clenching. 3. Prevalence of higher right side and higher left side of the mandible were almost same, and the EMG activity of higher side was not higher than that of the other side. 4. In the subjects with height difference of more than 5mm between both sides of the mandible, the early EMG activity on clenching were differed for the anterior temporalis, but the maximum activity were differed for the superficial masseter. 5. In the subjects with height difference of more than 5mm between both sides of the mandible, EMG activity of the anterior temporalis of the gum chewing side was not higher than that of the other side when chewing on the side of lower height, but in the subjects with height difference of less than 5mm, the EMG activity was higher than that of the other side.

Purpose: The frontal sinuses are a pair of triangularly shaped, air-filled chambers lined by mucoperiosteum and located between the inner and outer tables of the frontal bone. Until recently, our understanding of gender variations in craniofacial anatomy has been chiefly built upon anthropometric studies, which typically employ facial surface measurements or plain film radiography. The aim of this study i to determine the sizes of the frontal sinus in both sexes in Koreans. Methods: 95 Korean subjects who underwent maxillofacial 3-Dimensional computed tomography (CT) between January 2009 and December 2009 were enrolled. Frontal sinus dimensions and forehead measurements were taken at midline and at 10, 20, and 30 mm to the left and right of midline using sagittal, coronal, and axial images. The data was analyzed for significant differences between measurements made at the selected points in the frontal sinus, for left to right variations, for gender variations, and for racial differences. Results: The mean thickness of the anterior table ranged from 2.31 to 3.23 mm. Mean anteroposterior depth of the frontal sinus ranged from 7.38 to 9.45 mm and did not vary significantly at any distance from midline. Frontal sinus height was greatest at midline (mean=29.24 mm) and progressively lessened at lateral distances. Mean total width at the level of the supraorbital ridge was 53.66 mm. For all measurements, no significant left to right variation was noted. Comparing the sexes, males were found to have greater dimensions in most frontal sinus measurements, though these differences were only found to be significant at or close to midline. The male forehead was marked by more acute nasofrontal angle ($133.3^{\circ}$ versus $141.6^{\circ}$) and a steeper posterior forehead inclination ($14.9^{\circ}$ versus $7.7^{\circ}$). Conclusion: Using CT imaging, forehead and frontal sinus dimensions have been described. Generally, males had larger overall frontal sinus dimensions. And Korean had similar sized frontal sinus to Caucasian in height and width. But in AP distance Korean had lesser measurement. The result of this study may be helpful in the comprehension of normal size of frontal sinus in Korean.

Purpose : Total body irradiation (TBI) or whole body irradiation is used to acquire immune suppression, to treat malignant lymphoma and leukemia, and as an conditioning regimen for bone marrow transplantation. For these purposes, many methods were developed to obtain homogenous dose distribution. The objective of this study was to analyze and confirm the accuracy and the homogeneity of the treatment setup, the parallel opposed lateral technique, currently used in Seoul National University Hospital. Materials and Metheods : Surface dose data, measured with a thermoluminescent dosimeter, of 8 patients among 10 patients, who were given total body irradiation with the parallel opposed lateral technique between September 1996 to August 1998, at Seoul National University Hospital were analyzed. Surface doses were measured at the head, neck, axilla, thigh, and ankle level. Surface and midline doses were measured with similar set-up and technique in the Humanoid phantom. Results : Measured surface doses relative to prescribed dose for the head, neck, axilla, thight, and ankle leve were $91.3{\pm}7.8,{\;}98.3{\pm}7.5,{\;}95.1{\pm}6.3,{\;}98.3{\pm}5.5$, and $95.3{\pm} 6.3\%$, respectively. The midline doses of the head, neck, axilla, thigh, and ankle level estimated from the surface-to-midline ratios in the Humanoid Phantom were $103.4{\pm}9.0,{\;}107.8{\pm}10.5,{\;}91.1{\pm}6.1,{\pm} 93.8{\pm}4.5,{\;}and{\;}104.5{\pm}9.3\%$, respectively. Measured surface doses and estimated midline doses ranged from $-8.9\%$ to $+7.8\%$. Midline doses at the neck and the axilia level deviated more than $5\%$ from the prescribed doses. The difference of the estimated midline doses at the neck and the axilla level and the actual doses were attributed to the thickness differences between the Humanoid phantom and the patients. Conclusion Distribution of the midline doses as well as the suface doses were measured to be within $-8.7\~{\pm}7.8\%$ range. Actual dose distribution in the patient is expected to be better than the measured dose range mainly attributed to thickness difference between the patient and the Humanoid phantom.
