Purpose: To analyze the radiographic results between the simple bone excision and simple bone excision and posterior tibial tendon advancement for prehallux. Materials and Methods: Thirty-four patients who underwent operative treatment for prehallux between 1995 and 2000 were reviewed. Twenty-six patients who underwent simple bone excision and posterior tibial tendon advancement and eight patients who underwent simple bone excision were available for follow-up. Follow-up averaged 44 months(15-59 months). We evaluated and compared the cuboidal height and the talo-1st metatarsal angle in the preoperative and postoperative radiography. Results: The average span of disappearing pain is 3.7 months(2-7 months) after the operation. Mean cuboidal height and talo-1st metatarsal angle were increased $6.7{\pm}1.8mm$, $5.0{\pm}2.1^{\circ}$ before to $7.8{\pm}0.2mm$, $5.6{\pm}0.7^{\circ}$ after simple bone excision and posterior tibial tendon advancement. Mean cuboidal height and talo-1st metatarsal angle were increased $6.6{\pm}0.7mm$, $4.6{\pm}1.1^{\circ}$ before to $7.7{\pm}0.9mm$, $5.1{\pm}0.4^{\circ}$ after simple bone excision and posterior tibial tendon advancement. One case of extra-osseous migration of the Mitek anchor inserted into navicula was seen during the follow-up period. Conclusion: This study shows that the remarkable differences between the two procedures are not found. So, simple bone excision without advancement of posterior tibial tendon for prehallux can generate relatively good results.

Purpose: Several methods of the nipple reduction have been reported. However, the methods described previously are difficult or have some demerits. This study proposes a simple technique for reduction of the nipple height as well as diameter. Methods: The purposed nipple height is marked. A pentahedral design of excision was marked around the nipple. Local anesthetic solution was infiltrated and a 4 - 0 Nylon traction suture was applied at the nipple apex. Excision of the nipple inside both two triangles and a rectangle was made. Remaining two flaps were approximated using 5 - 0 Nylon simple interrupted sutures. However, a part of wound closure was not done in the central area of the nipple. Results: 83 patients(166 nipples) underwent this procedure from December 1999 to December 2008. Follow up ranged from 6 months to 2 years with a mean of 10 months. 78 patients were female and 5 patients were male. No major complication occurred and remaining scars were very inconspicuous. Conclusion: This simple technique has the advantage of nipple reduction in both height and diameter, and provides good aesthetic outcomes.

Acromioclavicular joint cyst is a extremely rare condition, usually occuring in the presence of a wide communication between glenohumeral and acromioclavicular joint in patients with a full thickness rotator cuff tear. Removal of cyst only is reported with high recurrence rate. There was no case previously reported in Korea. We report a case of recurred acromioclavicular joint cyst with a massive rotator cuff tear after simple excision, which was treated by excision of cyst, acromioplasty and resection of the lateral end of the clavicle.

Background Xanthelasma palpebrarum (XP) is a benign disorder manifesting as yellowish cholesterol-laden plaques on the eyelids. This paper presents the outcomes in patients with XP who have undergone surgical excision as the main modality of treatment. Methods A retrospective review of patients who received surgery for xanthelasma palpebrarum from March 2007 to March 2011 was conducted. Patients were classified into four grades according to the location and extent of the lesion, with grade I being the mildest and grade IV being the most diffuse. Simple excision was performed in grade I and II lesions, while local flaps and skin grafts were performed in the more advanced grades. Results Ninety-five cases from March 2007 to March 2011 were included in this study. 66 cases (70%), were treated by simple excision. Twenty-four cases (25%) and 5 cases (5%) were treated by simple excision in combination with or without local flaps and skin grafts. In approximately 1/4 of the patients, orbicularis oris muscle involvement was observed. 4 patients (4.2%) developed scar contracture postoperatively, which required a secondary procedure. Recurrence was reported in 3 patients (3.1%). Otherwise. There were no other reports of major complications or disfigurement. Conclusions We found that for lesions involving the deep dermis and/or muscle, surgical excision was the most appropriate therapeutic option.

73세 남자환자가 내원 8개월 전 좌측 원위 대퇴부의 연부 조직 종괴로 타 병원에서 절제술을 시행받은 뒤, 재발하여 4개월 뒤 재수술을 받았으나, 수술 부위의 치유되지 않는 창상을 주소로 내원하였다. 타 병원에서 시행한 조직 검사 소견은 단순 낭종이었다. 수술 소견상 종괴는 외측 광근의 근막층을 침범하면서 경계가 불규칙하며 주변으로 유착되어 있어, 종괴로부터 5 cm 경계를 확보하여 단순 절제술을 시행하였다. 본원 조직검사 결과, 악성 섬유성 조직구종으로 진단되어 추가적인 방사선 치료를 시행하였다. 수술 후 1년째까지, 크기가 증가되거나 타 부위에 전이되는 소견은 관찰되지 않았다. 단순 낭종으로 생각하고 절제술을 시행하였으나, 악성 섬유성 조직구종으로 확진되었던 경우로, 종양 절제술은 수술 전 세밀한 검사 및 진단이 필요할 것으로 사료된다.

Background Preauricular sinuses are congenital abnormalities caused by a failure of fusion of the primitive tubercles from which the pinna is formed. When persistent or recurring inflammation occurs, surgical excision of the infected tissue should be considered. Preauricular defects inevitably occur as a result of excisions and are often difficult to resolve with a simple suture; a more effective reconstruction technique is required for treating these defects. Methods After total excision of a preauricular sinus, the defect was closed by a plastic surgeon. Based on the depth of the defect and the degree of tension when apposing the wound margins, the surgeon determined whether to use primary closure or a posterior auricular flap. Results A total of 28 cases were examined. In 5 cases, including 2 reoperations for dehiscence after primary repair, reconstruction was performed using posterior auricular transposition flaps. In 16 cases of primary closure, the defects were closed using simple sutures, and in 7 cases, closure was performed after wide undermining. Conclusions If a preauricular defect is limited to the subcutaneous layer and the margins can be easily approximated, primary closure by only simple suturing may be used to perform the repair. If the defect is deep enough to expose the perichondrium or if there is tension when apposing the wound margins, wide undermining should be performed before primary closure. If the extent of the excision exposes cartilage, the procedure follows dehiscence of the primary repair, or the tissue is not sufficiently healthy, the surgeon should use a posterior auricular flap.

As the low power GPS signal is susceptible to interference, interference can seriously degrade the performance of GPS receiver. This paper designs a ANIEF(Adaptive Narrowband Interference Excision in Frequency domain) filter that removes narrow band interferences with low signal loss. This filter uses the pre-correlation technique and attempts to filter out the interference in the frequency domain. The interference excision performance of the designed filter is evaluated for various interferences using the ANIEF filter inserted GPS software receiver and the interference generator. Interferences considered in this paper are single-tone CWI(Continuous Wave Interference), multi-tones CWI, pulsed CWI, and swept CWI. The narrowband interference excision filter in frequency domain is very effective against various interferences and the strong interference with a simple structure. However, the signal power loss is unavoidable while transforming. In this paper, the hamming window and overlap technique are adopted to reduce the signal power loss. Finally, the interference excision performance and the reduced signal power loss of the ANIEF filter are shown.

Pyriform sinus cyst is a rare disease. This disease can be found by chance or appear as lymph nodes with cancer, infections, shortness of breath, or airway compromise, and can be an unusual cause of dysphonia. This paper presents a case of a pyriform sinus cyst in the pharyngeal wall of the left pyriform sinus, which presented as neck discomfort in a 63-year-old female. The plan was to remove this cyst with a transoral CO₂ laser because a CO₂ laser is a useful tool for removing cysts without bleeding and consuming time. The excision was performed successfully. Transoral laser pyriform sinus cyst excision is a simple, safe, and effective method for the treatment of pyriform sinus cysts. This procedure is likely to be used as a selective treatment when managing this condition.

Postoperative atlantoaxial rotatory subluxation (AARS) is a rare complication that develops almost exclusively in children following oropharyngeal and otologic surgeries, proposing that oropharyngeal inflammatory responses and excessive head rotation are responsible factors. However, there have been no reports of AARS after excision of a nevus on the head and neck. Here, we present two cases of AARS following limited head rotation during simple nevus excision. Patient 1, a 9-year-old girl, complained of neck pain and limited range of motion after excision of the nevus on the neck. After 2 months, computed tomography and magnetic resonance imaging finally revealed AARS with a ruptured transverse atlantal ligament. A month of halo traction was required for the treatment. Patient 2, an 11-year-old girl, presented with immediate pain and limited neck extension after tissue expander insertion under the upper chest and excision of the nevus on her left cheek. The diagnosis was promptly made using cervical spine radiography. A cervical collar was applied for 1 month. Both patients recovered without any complications after treatment. This report highlights the importance of suspicion for AARS after surgery regardless of surgical duration or amount of head rotation.

Accessory navicular is a congenital anomaly of the tuberosity of the navicular from a secondary ossification center. The accessory navicular is occasionally the source of pain and local tenderness over the medial side of midfoot. If conservative treatment fails for the painful accessory navicular, surgical treatment is required. There are several surgical option for accessory navicular, which vary from simple excision, percutaneous drilling, modified Kidner procedure and osteosynthesis of the accessory ossicle to the navicular body. In addition, symptomatic flatfoot deformity should be addressed concomitantly.
