Background: Preauricular sinuses represent a common congenital abnormality in children. Classically, a preauricular sinus manifests as a small opening, usually near the anterior limb of ascending helix. The difficulty in the surgical treatment of preauricular sinus is the high recurrence rate. The aim of this article is to review the outcomes of preauricular sinus and to introduce our surgical technique and its prognosis. Methods: A single-institutional retrospective review was performed for all patients who had undergone excision of congenital periauricular sinus between October 2007 and April 2014. Medical records were reviewed for demographic information, wound complication, and recurrence rate. The sinus tract was visualized with the aid of preoperative dye instillation and intraoperative probe insertion. The skin next to the sinus opening was incised elliptically, and the tract itself was dissected medially to the end of the sinus tract and posteriorly to the cartilage of the ascending helix. Results: The review identified 44 patients for a total of 57 preauricular sinus tracts. The mean age at time of operation was 16.3 years with a range from 9 months to 65 years. Unilateral preauricular sinus tract was present in 31 patients (11 right and 20 left preauricular tract), and 13 patients had bilateral sinus tract. None of the patients had experienced wound issues postoperative, and there were no recurrent sinus tract formation or infection. Conclusion: Using a combination of dye instillation, probe insertion, and modified dissection, we were able to achieve a recurrence free series of preauricular sinus tract excision among a heterogenous group of patients. A large patient series is necessary to replicate the results of this study.

Background: A schwannoma is a benign, slow-growing peripheral nerve sheath tumor that originates from Schwann cells. Orbital schwannomas are rare, accounting for only 1% of all orbital neoplasms. In this study, we retrospectively review orbital schwannomas and characterize clinical, radiologic, and histologic features of this rare entity. Methods: A retrospective review was performed to identify patients with histologically confirmed orbital schwannoma, among a list of 437 patients who had visited our hospital with soft tissue masses within the orbit as the primary presentation between 2010 and 2014. Patient charts and medical records were reviewed for demographic information, relevant medical and family history, physical examination findings relating to ocular and extraocular sensorimotor function, operative details, postoperative complications, pathologic report, and recurrence. Results: Five patients (5/437, 1.1%) were identified as having histologically confirmed orbital schwannoma and underwent complete excision. Both computed tomography (CT) and magnetic resonance imaging (MRI) studies were not consistent in predicting histologic diagnosis. There were no complications, and none of the patients experienced significant scar formation. In two cases, patients exhibited a mild postoperative numbness of the forehead, but the patients demonstrated full recovery of sensation within 3 months after the operation. None of the five patients have experienced recurrence. Conclusion: Orbital schwannomas are relatively rare tumors. Preoperative diagnosis is difficult because of its variable presentation and location. Appropriate early assessment of orbital tumors by CT or MRI and prompt management is warranted to prevent the development of severe complications. Therefore, orbital schwannomas should be considered in the differential diagnosis of slow-growing orbital masses.

Objective : Postoperative delirium is a common complication in the elderly after surgery but few papers have reported after spinal surgery. We analyzed various risk factors for postoperative delirium after spine surgery. Methods : Between May 2012 and September 2013, 70 patients over 60 years of age were examined. The patients were divided into two groups : Group A with delirium and Group B without delirium. Cognitive function was examined with the Mini-Mental State Examination-Korea (MMSE-K), Clinical Dementia Rating (CDR) and Global Deterioration Scale (GDS). Information was also obtained on the patients' education level, underlying diseases, duration of hospital stay and laboratory findings. Intraoperative assessment included Bispectral index (BIS), type of surgery or anesthesia, blood pressure, fluid balance, estimated blood loss and duration of surgery. Results : Postoperative delirium developed in 17 patients. The preoperative scores for the MMSE, CDR, and GDS in Group A were $19.1{\pm}5.4$, $0.9{\pm}0.6$, and $3.3{\pm}1.1$. These were significantly lower than those of Group B ($25.6{\pm}3.4$, $0.5{\pm}0.2$, and $2.1{\pm}0.7$) (p<0.05). BIS was lower in Group A ($30.2{\pm}6.8$ compared to $35.4{\pm}5.6$ in group B) (p<0.05). The number of BIS <40 were $5.1{\pm}3.1$ times in Group A, $2.5{\pm}2.2$ times in Group B (p<0.01). In addition, longer operation time and longer hospital stay were risk factors. Conclusion : Precise analysis of risk factors for postoperative delirium seems to be more important in spinal surgery because the surgery is not usually expected to have an effect on brain function. Although no risk factors specific to spinal surgery were identified, the BIS may represent a valuable new intraoperative predictor of the risk of delirium.

모기질세포종은 모발의 기질세포로부터 발생하는 양성 피부종양이다. 이것은 주로 두 경부 및 상지에 호발한다. 수술 전 진단의 정확성은 낮으며 단순방사선 검사만 시행한 후 절제생검을 하기도 한다. 저자들은 컬러도플러 초음파를 이용해서 쉽게 진단할 수 있었던 견부에 발생한 모기질세포종에 대해 보고하고자 한다. 초음파를 이용한 진단은 비용효과적인 측면 뿐만 아니라 종양의 내부에 대해 자세한 정보를 알 수 있다는 점에서 전산화 단층촬영이나 자기공명영상보다 더 손쉽고 유용한 진단방법으로 생각된다.

Background: Although there are several methods for evaluating bone quality, Hounsfield units (HU), a standardized computed tomography (CT) attenuation coefficient, provide a useful tool for estimating focal bone mineral density (BMD). The aim of this study is to investigate the HU for evaluating the degree of osteoporosis in greater tuberosity with regard to anchor positioning. Methods: Forty patients diagnosed as normal on shoulder CT were included and categorized according to age and gender. Axially sectioned CT images were processed to 3-dimensional models containing information about bone quality using Mimics (14.11 platform v14.1.1.1 Materialise). Three-dimensional anchors were simulated and positioned according to 6 regions of interest (ROI) in the greater tuberosity classified using Tingart's system. Mean HU of intra-anchor volumes in the 6 regions was measured. Results: A significant decrease in HU was observed with increasing age (p=0.0001) and menopause (p<0.001). A significant difference in HU was found between male and female groups with males showing the higher values (p=0.0001). HU of proximal areas of ROI was higher than those of distal areas (p<0.005). However, although mean HU of distal posterior ROI showed the lowest values, no statistically significant difference was found between anterior, middle, and posterior regions (p=0.087). Conclusions: Mean HU of ROIs provides a tool for preoperative assessment of focal BMD, which is a factor of suture anchor stability and can be used to aid decision-making regarding secure anchor positioning for rotator cuff repair. Our data support that the most secure point is the proximal regions of ROI.

Objectives: Quality of life (QoL) studies provide information about the impact of disease, the treatment of symptoms, and outcomes following treatment. The present study aims to evaluate the postoperative QoL of patients treated for oral cancer in a Nigerian government tertiary hospital. Materials and Methods: A prospective study on consenting patients with oral cancer was undertaken at Aminu Kano Teaching Hospital, Kano, Nigeria. The subjects completed the University of Washington QoL (UW-QoL) questionnaire one day prior to surgery and postoperatively after 7 days, 1 month, 3 months, and 6 months. Results: Sixty-eight patients with oral cancer were recruited. Of these, 38 were males, and 30 were females (male : female, 1.3 : 1). Twenty-four patients (12 males and 12 females) underwent surgery and completed postoperative QoL assessment using the UW-QoL questionnaire. Preoperative QoL mean score was 2.21, while postoperative mean scores after 1 week, 1 month, 3 months, and 6 months were 3.67, 3.46, 2.82, and 2.61, respectively. Conclusion: An improvement in QoL following surgical treatment for patients with oral cancer was observed. 'Appearance,' 'recreation,' and 'chewing' were identified as the most important determinants of postoperative QoL in patients with oral cancer in our study.

The aim of this paper was to propose a new method of bimaxillary orthognathic surgery planning and model surgery based on the concept of 6 degrees of freedom (DOF). A 22-year-old man with Class III malocclusion was referred to our clinic with complaints of facial deformity and chewing difficulty. To correct a prognathic mandible, facial asymmetry, flat occlusal plane angle, labioversion of the maxillary central incisors, and concavity of the facial profile, bimaxillary orthognathic surgery was planned. After preoperative orthodontic treatment, surgical planning based on the concept of 6 DOF was performed on a surgical treatment objective drawing, and a Jeon's model surgery chart (JMSC) was prepared. Model surgery was performed with Jeon's orthognathic surgery simulator (JOSS) using the JMSC, and an interim wafer was fabricated. Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, and malar augmentation were performed. The patient received lateral cephalometric and posteroanterior cephalometric analysis in postretention for 1 year. The follow-up results were determined to be satisfactory, and skeletal relapse did not occur after 1.5 years of surgery. When maxillary and mandibular models are considered as rigid bodies, and their state of motion is described in a quantitative manner based on 6 DOF, sharing of exact information on locational movement in 3-dimensional space is possible. The use of JMSC and JOSS will actualize accurate communication and performance of model surgery among clinicians based on objective measurements.

Objective : The purpose of this study was to compare computed tomographic angiography(CTA) with conventional cerebral angiography(CCA) and to assess usefulness of CTA in detection and anatomic definition of intracranial aneurysms of the circle of Willis in subarachnoid hemorrhage. Patients and Methods : Fifty consecutive patients with known or suspected intracranial saccular aneurysms underwent CTA with preoperative CCA from 1997 to 1999. Using surface shaded display post-processing technique, CTA was interpreted for the presence, location of aneurysms and anatomic features. The image obtained with CTA was then compared with CCA image. Results : In 47 patients, CCA revealed 57 cerebral aneurysms and CTA revealed 54 aneurysms. Two of the 57 cerebral aneurysms were located outside of the imaging volume of CTA and one case was misdiagnosed. The sensitivity of CTA was 94.7% and the specificity was 100%. The results obtained with CTA were, compared with the results obtained with CCA, equal in determining dome shape, direction and lobularity. However, CTA provided a 3-dimensional representation of aneurysmal lesion very useful for surgical planning. Moreover, CTA was useful for rapid and relatively noninvasive detection of aneurysms in the circle of Willis. Conclusion : CTA can be a diagnostic tool for the patients with acute subarachnoid hemorrhage due to a ruptured aneurysm of the circle of Willis and provides adequate anatomic detail for surgical planning, especially to complex cerebral aneurysms. However, we think CCA is necessary because of CTA limitations including its difficulty in detecting unusually located aneurysms(including those in cavernous sinus or distal artery) and combined vascular lesion (including arteriovenous malformation) and acquiring dynamic flow information.
