Background and Objectives:
This study aims to investigate the indications of external approach septoplasty and improvement in subjective symptoms and objective parameters in patients who underwent external approach septoplasty to correct septal deviation with various types of deformities.
Subjects and Methods:
Thirty-one patients who underwent external approach septoplasty from October 2014 to January 2019 were classified by direction, location, and degree of nasal septal deviation, septal shape and surgical techniques. Through acoustic rhinometry, the minimum cross-sectional area and nasal volume were measured before and after surgery. To evaluate the improvement in symptoms, the Nasal Obstruction Symptom Evaluation (NOSE) survey and nasal congestion visual analogue scale (VAS) were also measured.
Results:
We found significant correlations between: the direction and degree of nasal septal deviation; the location and degree of nasal septal deviation; septal shape and location of the nasal septal deviation; septal shape and surgical techniques; and the degree of nasal septal deviation and presence of spreader grafts. The NOSE scale following external approach septoplasty improved from 14.7±4.4 to 3.1±3.2 (p<0.001), while the VAS score improved from 7.2±2.3 to 1.2±1.4 (p<0.001). Also, acoustic rhinometry showed that the minimum cross-sectional area and nasal volume at the convex side of nasal cavity significantly increased after surgery.
Conclusion
The external approach septoplasty is a surgical technique that is effective not only in improving subjective symptoms, but also in improving objective parameters. External approach septoplasty could be used in case of caudal and/or dorsal nasal septal deviation.

The authors performed a retrospective review to find out optimal treatment plan in infantile fistula-in-ano. There were seventy-one patients in a 2-year period. All were male and other clinical characteristics were similar to previous reports. The onset in 60 patients(97%) of the cases was in the first 1 year of alee, especially in the first 3 months(52%). We investigated patterns of disease progression in multiple-lesion cases(19cases 29%). In 5 out of 9 cases of which we could identify the patterns, new lesion developed from 1 month to 4 months after index lesion. Fifty Patients underwent fistulotomy under principle of early surgical intervention, No recurrence was found except 2cases who needed second operation during 30 months of median follow-up(23~48 months). In 21 patients whose parents did not want operation, we performed simple drainage and followed-up. Six out of 12 patients who could be communicable had no fistula-related symptoms from 20 months to 31 months. This suggests that simple drainage has therapeutic effect in some portion of infantile abscess. We conclude that simple drainage should be initial treatment of choice in infantile perianal abscess. We suggest that definite operation for recurrent abscess and fistula with relatively mild symptoms should be delayed until 1-year of age because of interval ccurrence of multiple lesions and therapeutic effect of simple drainage.

BACKGROUND: Polyethylene glycol(PEG) has been the most widely used colonic lavage solution. But large volume and salty taste of PEG solution is a problem which can lead to the noncompliance and the poor bowel cleansing. Recent reports have suggested that sodium phosphate solution of much smaller volume is more effective in colon cleansing ability and more easier to complete. Therefore, this study was designed to compare two solutions for colonoscopy and to determine the differences in either patient compliance or cleansing ability. METHOD: Eighty-two patients were randomized to take either oral sodium phosphate solution or 2 liter of PEG solution. Patient's discomfort and tolerance during ingestion was asessed by questionnaire and one colonoscopist who did not know the type of solution, assessed colonic preparation status. RESULTS: Among 25 patients experiencing two separate colonoscopies with PEG solution and sodium phosphate solution respectively, 19(76%) patients preferred sodium phosphate solution. Sodium phosphate solution was found to be easier to take. Sodium phosphate caused thirst more frequently(p=0.013) than PEG solution. Particulate stool and water retention status were similar in two groups. Gas bubble formation that disturbs luminal observation was more frequently found in sodium phosphate preparation group(P=0.00). Sodium phosphate was more effective in right colon cleansing ability than PEG preparation(P=0.04). The Colonoscopist assessed sodium phosphate as "good" in 47.2% vs 58.6% after PEG preparation as a whole, but there was no statistical difference. CONSLUSION: Sodium Phosphate solution is better tolerated and more easier to take than PEG solution. Gas bubble formation is a correctable problem, but right colonic cleansing effect is not. Our results showed that sodium phosphate is likely to be more effective in colonic cleansing effect comparing to polyethylene glycol solution.

OBJECTIVE:
The purpose of this study was to compare the static (SFF) and kinetic frictional forces (KFF) of a computer-aided design and computer-aided manufacturing lingual bracket (CAD/CAM-LB) with those of conventional LB (Con-LB) and Con-LB with narrow bracket width (Con-LB-NBW) under 3 tooth displacement conditions.
METHODS:
The samples were divided into 9 groups according to combinations of 3 LB types (CAD/CAM-LB [Incognito], Con-LB [7th Generation, 7G], and Con-LB-NBW [STb]) with 3 displacement conditions (no displacement [control], maxillary right lateral incisor with 1-mm palatal displacement [MXLI-PD], and maxillary right canine with 1-mm gingival displacement [MXC-GD]; n = 6/group). While drawing a 0.016-inch copper or super-elastic nickel-titanium archwire with 0.5 mm/min for 5 minutes in a chamber maintained at 36.5℃, SFF and KFF were measured. The Kruskal-Wallis method with Bonferroni correction was performed.
RESULTS:
The Incognito group demonstrated the highest SFF, followed by the 7G and STb groups ([STb-control, STb-MXLI-PD, Stb-MXC-GD] < [7G-MXC-GD, 7G-MXLI-PD, 7G-control] < [Incognito-MXLI-PD, Incognito-control, Incognito-MXC-GD]; p < 0.001). However, there were no significant differences in SFF among the 3 displacement conditions within each bracket group. Within each displacement condition, the Incognito group demonstrated the highest KFF, followed by the 7G and STb groups ([STb-control, STb-MXLI-PD] < Stb-MXC-GD < 7G-MXLI-PD < [7G-control, 7G-MXC-GD] < [7G-MXC-GD, Incognito-MXLI-PD, Incognito-control] < [Incognito-control, Incognito-MXC-GD]; p < 0.001). MXC-GD exhibited higher KFFs than MXLI-PD in the same bracket group.
CONCLUSIONS
The slot design and ligation method of the CAD/CAM-LB system should be modified to reduce SFF and KFF during the leveling/alignment stage.

The pathogenesis of thrombocytopenia in the gestational thrombocytopenia is not understood.This syndrome may represent either the de novo development of ITP or an accelerationof the physiologic pattern of increased platelet destruction that occurs during gestation. Thisdisorder is not easily distinguishable from classical ITP. However, the recognition and diagnosisof this syndrome is important because infants born to individuals with gestational thrombocytopeniaappear to have a markedly reduced risk of developing thrombocytopenia when comparedto infants born to patients with a history of ITP antedating pregnancy. We represent a caseof delivery in severe gestational thrombocytopenia with brief review of the literature.

PURPOSE: For hypertrophic scars and keloids no universally effective treatment modality exists. Surgical revision, intralesional steroid injection, silicone gel sheeting, pressure, laser, and others have been used with variable success, but many treatments are associated with high recurrence rates. Although optimal treatment remains undefined, successful treatment can be obtained through a combined therapeutic approach. METHODS: We used three therapeutic modalities in combination, which are intralesional injection of triamcinolone acetonide, silicone gel sheeting, and 585 nm flashlamp-pumped pulsed dye laser. Fifty-eight cases of hypertrophic or keloid scar were treated by combined therapeutic regimen for mean period of 18 months. The changes of thickness, color, and pliability of scars were evaluated with clinical photographs by grading scale. RESULTS: As summing the grades and categorizing the result into three group, we obtained 28% good, 67% fair, and 5% poor results. There was a desirable improvement of scars with insignificant adverse effects. CONCLUSION: Combination of intralesional steroid injection, silicone gel sheeting, and pulsed dye laser can lead to successful treatment of hypertrophic scar and keloid.

OBJECTIVES: Suppression head impulse paradigm (SHIMP) in video head impulse test is now newly used to test vestibular function. The aim of this study was to analyze normative values of SHIMP for healthy Korean subjects in each decade of life. METHODS: SHIMP and HIMP responses were measured with the video head impulse test in 70 healthy subjects. Vestibulo-ocular reflex gain and anticompensatory saccade were analyzed and compared at each decade of life. RESULTS: All subjects produced anticompensatory saccades in SHIMP. Gain values did not vary significantly with age. Gain values in SHIMP were lower than gain values in HIMP. The gain values of rightward impulse were higher than the gain values of leftward impulse. CONCLUSIONS: Gain values and anticompensatory saccades in SHIMP were consistently equal in each decade of life. Normative values of SHIMP seems largely unaffected by aging.
