Recurrent laryngeal nerve paralysis is the most common and serious complication after thyroid cancer surgery. The objective of this study was to report the advantages of the vein wrapping technique for nerve reconstruction in patients with thyroid cancer invading the recurrent laryngeal nerve and its effects on postoperative phonatory function. The subjects were three patients who underwent resection of the recurrent laryngeal nerve during surgical extirpation of papillary thyroid cancer. Free ansa cervicalis nerve graft or direct neurorrhaphy with a vein wrapping technique was used to facilitate nerve regeneration, protect the anastomosed nerve site mechanically, and prevent neuroma formation. One-year postoperative laryngoscopic examination revealed good vocal cord mobility. Maximum phonation time ($19.5{\pm}0.3$ sec) was longer than a previously-reported value in conventional reconstruction patients ($18.8{\pm}6.6$ sec). The present phonation efficiency index ($7.88{\pm}0.78$) was higher than that previously calculated in conventional reconstruction ($7.59{\pm}2.82$). The mean value of the Voice Handicap Index-10 was 6, which was within the normal range. This study demonstrates improvement in phonation indices measured 1 year after recurrent laryngeal nerve reconstruction. Our results confirm that the vein wrapping technique has theoretical advantages and could be favored over conventional reconstruction techniques for invenerate nerve injuries.

Objectives: This study was to evaluate the effect of vertical bone gain and success rate and analyze the failure cases using the hydrodynamic piezoelectric internal sinus elevation (HPISE) technique. Materials and Methods: Patients who had been operated in the three centers including Daegu Catholic University Medical Center were selected for this study. The mucoperiosteal flap was elevated, and the sinus floor was then broken by specially designed piezoelectric insert, with hydraulic pressure applied to the sinus membrane for even elevation. Afterward, implants were placed. Panoramic radiogram or computed tomogram was taken before and after surgery and at the second operation and prosthesis placement. Later, changes in vertical height were measured and compared. The survival rate was based on the criteria of Buser et al. and Cochran et al. Results: In this study, 8 implants failed out of a total of 169 implants, resulting a success rate of 95.3%. These failure cases were due to insufficient initial stability or sinus membrane perforation. The mean of radiographic vertical height change at prosthesis placement was 5.7 mm (0.5-10.5 mm). Conclusion: In this study, HPISE technique was found to be a predictable treatment for atrophic maxilla and an alternative technique to the lateral approach.

Purpose: Posttraumatic nasal deformities might not be corrected adequately by conventional osteotomy techniques when the configuration of the nasal bone has been changed due to malunion. To consistently obtain good aesthetic and functional results, the anatomic reduction of malunion sites of the nasal bone is important. The purpose of this study is to present an osteotomy technique, including refracture along malunion sites and anatomical reduction of a malformed nasal bone, for the correction of a posttraumatic deviated nose. Methods: From March of 2003 to May of 2004, 27 patients, who underwent corrective rhinoplasty for the correction of bony pyramid deviation, were included in this study. Postoperative results of the technique were evaluated objectively at 1 year after surgery regarding nasal midline location, nose symmetry, and nasal contour. Results were rated as excellent, good, fair, or poor. All patients were also evaluated subjectively for cosmetic improvement, changes in breathing, and overall satisfaction. Results: Objective analysis of the outcomes revealed an excellent result in 17 patients(63%), good in 9(33%), and fair in 1 patient(4%). No case evaluated had a poor result. Regarding subjective analysis, 19 patients(70%) evaluated the cosmetic outcome as perfect. Among the 21 patients with preoperative airway problems, 19 patients(90%) reported improved breathing post-operatively. Patients' overall satisfaction levels were also very positive. No postoperative complications occurred during the 14 month mean follow-up period. Conclusion: The osteotomy technique presented in this study is simple, effective, and safe for correcting posttraumatic nasal deviation, and also produces consistent results.

Tibial eminence fracture is caused by distortion, excessive flexion and extension, varus and valgus injury of the knee joint in the form of avulsion fracture. A failure over the exact anatomical reduction of fragment can lead to instability and limitation of joint motion. Recently, a variety of arthroscopic assisted reduction and fixation technique have been used. In the tibial eminence fracture, we created an arthroscopic pull-out wire fixation technique using a cannulated screw that is easy and more convenient than in the conventional technique. So we report this technique with a review of current literatures.

Breast animation deformity (BAD) has been reported to occur after submuscular implant placement following breast augmentation and immediate breast reconstruction. Despite its apparent impact on patients' quality of life, BAD has only recently become a topic of general concern. Its incidence and etiology have yet to be established. The aim of this systematic review was to identify papers that clearly defined and classified BAD and described how the degree of animation was assessed. We performed a search in PubMed and Embase. Studies meeting the inclusion criteria that described BAD after implant-based breast augmentation or immediate breast reconstruction were included. After screening 866 publications, four studies were included: three describing BAD after breast augmentation and one describing BAD after immediate breast reconstruction. The median percentage of patients with some degree of BAD was 58%. The highest percentages were found in patients operated on using the Regnault technique or the dual-plane technique (73%-78%). The lowest percentages were found following the dual-plane muscle-splitting technique (30%) and the triple-plane technique (33%). We found no studies meeting the inclusion criteria that analyzed BAD after prepectoral implant placement. This review of the current literature suggests that the degree of BAD is proportional to the degree of muscle involvement. Evidence is scarce, and the phenomenon seems to be underreported. Future comparative studies are warranted.

Management of postoperative tarsal tunnel syndrome is a perplexing problem to the surgeons. Autogenous vein wrapping graft is a effective method to decompress the tarsal tunnel. We treated 2 cases of postoperative tarsal tunnel syndrome with autogenous saphenous vein wrapping graft technique, and could get good results. Autogenous vein wrapping graft seems to be a good technique for tarsal tunnel syndrome with severe adhesion, particularly after surgery, and postoperative nerve adhesion can be prevented.

Corner mouth lift is in increasing demand among young patients in East Asia. Although various surgical methods exist for corner mouth lift, many patients are reluctant to undergo surgery due to fears of postsurgical scarring. We present a new technique aimed at reducing postoperative scarring. The technique involves triangular excision of the corner of the mouth and incision of the commissure with transposition of a lateral vermilion flap to lift the corner of the mouth. The muscle around the corner of the mouth is dissected to release tension. The corner mouth lift was successfully performed in all patients. It can be effectively used even in patients, such as young Asian women, who are susceptible to hypertrophic scars.

Ascending aortic aneurysms are usually treated with graft replacement under cardiopulmonary bypass. However, if a candidate for off-pump coronary artery bypass grafting has an enlarged ascending aorta, surgeons may consider wrapping it without cardiopulmonary bypass. Here, we report a 78-year-old female who underwent successful wrapping of the ascending aorta concomitant with off-pump coronary artery bypass grafting, using a new wrapping technique that involves multiple bootstraps.

Acromial fractures are well-documented complications subsequent to reverse shoulder arthroplasty (RSA), and most appear as stress fractures with no history of single trauma. To date, no study has reported the occurrence of acute displaced acromial fracture due to sudden strong deltoid contraction during heavy work. Displacement of the fracture results in a challenging surgery since it is difficult to obtain adequate fixation in thin and osteoporotic bones. We report a rare case of acute displaced acromial fracture after successful RSA treatment, using a novel technique of open reduction and internal fixation, applying two 4.5 mm cannulated screws and lateral clavicle precontoured plate.

Sacroiliac dislocation is the separation of the iliac wing from the pelvic bone and needs to be repaired by surgery. Corrective surgical methods include open reduction and minimally invasive techniques. In the present study, we used a minimally invasive surgical technique in seven dogs with sacroiliac dislocation. Five cases had unilateral sacroiliac joint luxation and two cases had bilateral sacroiliac joint luxation; all were referred to hospital after being hit by an automobile. All cases were treated with a fluoroscope-assisted, minimally invasive technique. Patients were evaluated by measuring surgery time, postoperative ambulatory time, and calculating pelvic canal diameter ratios. Surgery time was measured from initial incision to completion of skin closure. Mean surgery time was 30.6 minutes in unilateral sacroiliac joint luxation and 68 minutes in bilateral sacroiliac joint luxation. Mean preoperative pelvic canal diameter ratio was 1.22 (${\pm}0.27$), immediate postoperative pelvic canal diameter ratio was 1.26 (${\pm}0.10$), and at 2 weeks after surgery, the pelvic canal diameter ratio was 1.37 (${\pm}0.22$). All cases were ambulatory within 1 week and mean postoperative ambulatory time was 5 days. Based on the results, the use of a minimally invasive technique for correction of sacroiliac dislocation can decrease surgical time, lessen operative and postoperative burdens on patients, and provide owners with a good prognosis.
