In adult congenital muscular torticollis (CMT) patients, physical therapy is not as effective because the development of sternocleidomastoid muscle (SCM) muscle is complete. While surgical release can address CMT in adult patients, the risk of general anesthesia and visible postoperative scar is a concern, expecially in patients with mild symptoms. In this paper, we report our experience in treating such patients with minimal-incision myotomy under local anesthesia. A review was performed for all adult patients who had undergone the simple myotomy procedure. Surgical indication was reserved for patients with mild fibrotic band in the SCM muscle with minimal lengthdiscrepancybetween the muscles. All patients had recognizable head tiltand palpation of fibrotic band on affected side of the neck. Surgical details are described in the main body of text. Three female patients had undergone the procedure. Torticollis was resolve in all patients with complete restoration of ranage of motion. There were no postoperative complications, and patient satisfaction was high. We have reported three cases of mild CMT in adult female patients, who had undergone minimal-incision myotomy under local anesthesia. Outcomes were satisafactory with no morbidity to report. With careful patient selection, this method offers an alternate treatment option for adult CMT patients with mild symptoms.

Objective : A superciliary keyhole approach is an attractive, minimally invasive surgical technique, yet the procedure is limited due to a small cranial opening. Nonetheless, an unruptured supraclinoid internal carotid artery (ICA) aneurysm can be an optimal surgical target of a superciliary approach as it is located in the center of the surgical view and field. Therefore, this study evaluated the feasibility and surgical outcomes of a superciliary keyhole approach for unruptured ICA aneurysms. Methods : The authors report on a consecutive series of patients who underwent a superciliary approach for clipping unruptured ICA aneurysms between January 2007 and February 2012. The data were compared with a historical control group who underwent a pterional approach between January 2003 and December 2006. Results : In the superciliary group, a total of 71 aneurysms were successfully clipped without a residual sac in 70 patients with a mean age of 57 years (range, 37-75 years). The maximum diameter of the aneurysms ranged from 4 mm to 14 mm (mean${\pm}$standard deviation, $6.6{\pm}2.3$ mm). No direct mortality or permanent morbidity was related to the surgery. The superciliary approach demonstrated statistically significant advantages over the pterional approach, including a shorter operative duration (mean, 100 min), no intraoperative blood transfusions, and no postoperative epidural hemorrhages. Conclusion : A superciliary keyhole approach provides a sufficient surgical corridor to clip most unruptured supraclinoid ICA aneurysms in a minimally invasive manner.

As a surgical treatment of ulnar nerve entrapment syndrome includes simple decompression, medial epicondylectomy, and anterior transposition of the ulnar nerve into a subcutaneous or submuscular bed have been widely used. Despite many reports of these surgical procedure, there is little to guide the choice of one surgical technique. The purpose of our study is to analyse clinical and electrodiagnostic result after minimal invasive decompression by decompression and medial epicondyloplasty(deepening of ulnar groove). We have experienced 9 cases of ulnar nerve entrapment syndrome who were treated with decompression and medial epicondyloplasty. Male were five and female were four. The mean age at operation was 36 years ranging from 23 to 47 years. Operative procedure was to incise the medial intermuscular septum and aponeurotic arch of flexor carpiulnaris and to deepen the ulnar groove. Patients are allowed to do range of motion(ROM) exercise on the average 5days. All patient were relieved pain and improved motor and sensory function, and this procedure allows early ROM exercise after operation because the muscle have not been detached.

Purpose: Treatment for periodontitis has evolved over the years as new technologies have become available. Currently, lasers seem attractive as a treatment modality, but their effectiveness needs to be verified. The purpose of this project was to evaluate Laser Assisted New Attachment Procedure^® (LANAP^®) surgery as a single treatment modality. Methods: As part of a mandatory training program for periodontists and other dentists, 22 consecutive patients diagnosed with moderate to severe periodontitis (probing depth [PD] up to 11 mm) were treated with the LANAP^® surgical approach using a 1064-nm Nd:YAG laser as part of a multi-step protocol. Following single-session active therapy, they were entered into a maintenance program. Their clinical status was re-evaluated at 12-18 months following surgery. Results: All 22 patients completed the 12- to 18-month follow-up. PD, clinical attachment level, and furcation (FURC) showed substantial improvement. Recession was minimal (mean, 0.1 mm), while 93.5% of PD measurements were 3 mm or less at re-evaluation. Furthermore, 40% of grade 2 FURC closed clinically. Conclusions: Within the limits of this case series, LANAP^® was found to be an effective, minimally invasive, laser surgical therapy for moderate to advanced periodontitis.

Regarding the removal of a gastric bezoar, laparoscopic surgery was performed and it was shown that the laparoscopic approach is safe and feasible. However, the laparoscopic method has the risk of intraabdominal contamination, when the gastric bezoar is retrieved from the gastric lumen in the peritoneal cavity. We developed and applied a new procedure for the removal of the gastric bezoar using one surgical glove and two wound retractors as a fashion of intragastric single port surgery. Herein we present this new minimal invasive procedure, so named "hybrid access surgery" which involves the use of existing devices and overcomes the weakness of laparoscopic removal of the gastric bezoar. Our new procedure, combining the concept of intragastric and single port access, is acceptable and feasible to retrieve the gastric bezoar. In the future, this procedure may be one of the alternative procedures for retrieving gastric bezoar even when it is incarcerated in the pylorus.

Purpose: In general, orientals including Korean, have a mesocephalic face whereas Caucasians, among the western, have a dolichocephalic face. Unlike the western, in orientals including Korean, prominent malar bones are recognized as stubborn and unattractive appearance. That is why reduction malarplasty is one of the most popular aesthetic surgical procedure in Korea. Many surgical methods to reposition prominent malar bones have been performed by means of a coronal incision or a combined incisions, using both the intraoral and the external incision. Bicoronal approach has advantage such as wide operative field, easy to maintain symmetry and possibility of combining facial lift but has shortcoming, such as external scars, long operative time, and the possibility of facial nerve or artery injury. Intraoral approach has advantages of short operative time, simplicity of procedure and no external scar. But this approach is associated with problems of cheek drooping, limited exposure and difficulty in making symmetry. Methods: During 8 years, we performed a reduction malarplasty without internal fixation through an minimal intraoral incision and dissection in 39 patients. Results: The patients were followed for 46 months, with satisfactory results and no cheek drooping. There was no patient who want to revise the inappropriate operative result such as asymmetry and incomplete correction. Conclusion: We conclude that minimal intraoral incision and dissection could acquire satisfactory result of reduction malarplasty along with prevention of cheek drooping.

Background Perforator artery flaps based on the branches of intercostal arteries and lateral thoracic artery can be used for reconstruction after breast-conserving surgery (BCS). Although described more than a decade ago, these have not been adopted widely in clinical practice. We report on short-term and long-term surgical outcomes of partial breast reconstruction using chest wall perforator flaps from a prospective multicenter audit. Methods All patients operated for BCS and partial breast reconstruction using intercostal artery perforator or lateral thoracic artery perforator flaps from January 2015 to October 2018 were included in the analysis. Oncoplastic breast surgeons with appropriate level of training performed all tumor excisions and reconstructions as a single-stage procedure. Patient characteristics, treatment details and surgical outcomes were noted. Specific outcomes recorded were margin re-excision and complication rates. Results One hundred and twelve patients underwent the procedure in the given study period. The median age was 54 years. Median specimen weight was 62.5 g and median volume of excision was 121.4 mL. Fifteen patients (13.39%) underwent a margin re-excision for close or positive margins without additional morbidity. One patient required a completion mastectomy. Eight patients (7.14%) had an early complication. None of the patients required a contralateral symmetrization procedure. The results were comparable across the participating centers. Conclusions Chest wall artery perforator-based flaps are an excellent option for lateral and inferior quadrant partial breast reconstructions. The short and long-term surgical outcomes are comparable across sites and can be performed with minimal morbidity. Patient-reported outcome measures need to be studied.

Preoperative surgical simulation in orthognathic surgery has progressed in recent years; the movement of the mandible can be anticipated through three-dimensional (3D) simulation surgery before the actual procedure. In this case report, the mandible was moved to the intended postoperative occlusion through preoperative surgical 3D simulation. Right-side condylar movement change was very slight in the surgical simulation, suggesting the possibility of mandibular surgery that included only left-side ramal osteotomy. This case report describes a patient with a mild asymmetric facial profile in which the mandibular menton had been deviated to the right and the lips canted down to the left. Before surgery, three-dimensional surgical simulation was used to evaluate and confirm a position for the condyle as well as the symmetrical postoperative state of the face. Facial asymmetry was resolved with minimal surgical treatment through unilateral intraoral vertical ramus osteotomy on the left side of the mandible. It would be a valuable complement for the reduction of the surgical treatment if one could decide with good predictability when an isolated intraoral vertical ramus osteotomy can be done without a compensatory osteotomy on the contralateral side.

Recently the trend of surgical procedure for treatment of lumbar benign disease is a minimally invasive surgery due to small incision, minimal blood loss, and a short hospital day. By using a microscope or an endoscope, and other surgical equipment, a delicate manipulation in a narrow space became feasible, consequently, to secure a wider view with small incision, appropriate retractors are required. But the various tubular retractor systems are expensive and have some problems. We modified Thoracoport [Auto Suture Co., Norwalk, CT] by making a window at the distal end of trocar and used it as a tubular retractor in surgical procedure for treatment of lumbar benign disease. This modified tubular retractor is docked closely on the curved lamina and provides a wider view. We used it as a tubular retractor also in lumbar bilateral decompression involving a unilateral approach. But this trocar has the limited sizes [diameter and length], and also it is difficult to fix the retractor or change the direction of retractor. And then, we propose a more modified Thoracoport with various sizes and attaching the settling holders to the head of tubular retractor to be able to fix the retractor.

Although lobectomy remains the gold-standard surgical treatment for non-small-cell lung cancer, the frequency of thoracoscopic segmentectomy is increasing. Multiple factors must be considered in the choice of the procedure, ranging from adequate surgical planning or simulation, tumor localization, and identification of the intersegmental plane to severing the intersegmental plane to achieve an oncologically safe surgical margin with no or minimal manual palpation and different landmarks. In this article, we present an overview of methods for each procedural step of thoracoscopic segmentectomy, from preoperative planning to division of the intersegmental plane.
