Video-assisted thoracic surgery [VATS is emerging as a viable alternatives to thoracotomy when surgical treatment of spontaneous pneumothorax is required.Apical blebs and bullaes of the lung can be resected,and pleural abrasion can be accomplished with minimal postoperative pain and a shorter postoperative stay in hospital. We compared our results with thoracoscopic management of spontaneous pneumothorax in 20 patients [group I with a group of 32 patients previously subjected to lateral limited thoracotomy [group II . Indications for operation, sex distribution, and average age [groupI, 24.7 years ; group II, 34.4 years were comparable. Operation time [112.42 54.7 min versus 124.8 35.3 min ; P 0.03 and chest tube duration [64.4 52.3 hours versus 97.7 45.4 hours ; P 0.01 were less in group I. Postoperative hospital stay was less in group I[3.84 0.99 days;P 0.01 , as was the use of parenteral narcotics after 48 hours. [5/20=25% versus25/32=78% . Pain was quantitated by verbal rating scale in postoperative 1 to 3 days. Patients undergoing VATS experienced significantly less postoperative pain. Postoperative complication was less in group I[1/20=5% versus 3/32=8.3% . In conclusion, Video-assisted thoracoscopic management of spontaneous pneumothrax allows performance of the standard surgical procedure while avoiding the thoracotomy incision.Video-assisted thoracic surgery [VATS is safe and offers the potential benefits of shorter postoperative hospital stays and less pain with cosmetic benefits.

Background Dimples on the cheeks can make the smile look more cheerful and attractive. Therefore, some people who do not have dimples may choose to undergo dimple creation surgery. Although dimple surgery is quite common, those desiring this procedure often lack information about it. Therefore, we conducted the present study to share our surgical tips and clinical experiences regarding safe dimple creation surgery. Methods This study included 2,048 patients who underwent dimple creation surgery at our plastic surgery clinic between April 2010 and June 2014. These patients were selected from those who displayed no scarring from injury or tumor removal in the central face during the presurgical evaluation. Medical records were used to identify the age and sex of each patient, the location of dimple creation, any postoperative complications, reoperation, and the reason for reoperation. Results Of the 2,048 patients, 159 (7.7%) underwent reoperation. The reason for reoperation was undercorrection in 78 cases (49.0%), disappearance of the dimple in 62 cases (38.9%), and overcorrection in nine cases (5.6%). Five patients (3.1%) had their stitches removed to eliminate the created dimple because they changed their minds, and five patients (3.1%) had their stitches removed because of infection. No patients reported complications after reoperation, and no other complications, such as hyperpigmentation or foreign body reaction, were observed. Conclusions Safe surgery with minimal complications and satisfying cosmetic results can be achieved via accurate knowledge of the relevant anatomy and its relationship with dimples, as well as appropriate surgical methodology.

Background: The reconstruction of large full-thickness alar defects requires complex surgical procedures that are usually performed in two stages, with concomitant disadvantages in terms of patient trauma, surgical risk, and cost. This study presents a functional folded nasolabial island flap (FNIF) that can be used to repair large-sized full-thickness alar defects in a straightforward manner. Methods: This retrospective study included seven patients who received a FNIF for a full-thickness alar defect between January 2007 and December 2020. The FNIF is different from the conventional nasolabial flap in that it is folded and twisted to achieve nostril reconstruction with a satisfactory three-dimensional mucosal lining in a single stage. The cosmetic and functional results of FNIF were evaluated by both patients and physicians. Results: The age ranged from 51 to 82 years (mean, 65.6 years). The causes of the defects were squamous cell carcinoma, basal cell carcinoma, and trigeminal trophic syndrome. The nostril lining did not collapse, there was no hypertrophic scarring, and air movement through the nostrils on the flap side was normal. Overall, FNIF produced excellent aesthetic and functional outcomes, with minimal patient discomfort. There were no postoperative complications. Conclusion: Compared with existing reconstruction methods for large full-thickness alar defects, FNIF can easily achieve aesthetic and functional success in a single-stage procedure. It provides satisfactory results for both the patient and the surgeon.

Subcutaneous cervicofacial, mediastinal emphysemas are complications associated with head and neck surgery, trauma, infectious processes, tooth extraction. Drill cooling stream and dental syringe air ject are the sources of high pressure air that may enter exposed soft tissue. Since the introduction of the high-speed air turbine drill in the 1960s, The incidence of iatrogenic subcutaneous emphysema has increased. Most cases begin to resolve after 2 to 3 days and residual swelling is usually minimal at the end of 7 to 10 days. Surgical approach is not advised because it is likely to be ineffective. The differential diagnosis of neck swelling after dental procedure includes hematoma, cellulitis, angioedema, allergic reaction, subcutaneous emphysema. We report a rare case of patient with subcutaneous cervicofacial emphysema and mediastinal emphysema secondary to third molar extraction.

Total knee arthroplasty has become a common procedure for treatment of severe osteoarthritis, rheumatoid arthritis and post-traumatic arthritis. In the past, failure of total knee arthroplasty was commonly attributable to aseptic loosening, often associated with component malalignment, soft tissue imbalance. With improved surgical instrumentation and soft tissue balancing techiniques, failure secondary to mechanical loosening has been minimal. But surgeons are still dissatisfied with implant malalignment. Correct tibiofemoral alignment seems to be particularly important since it is generally agreed that axial deviation and imprecise implantation may lead to loosening of the implant component. Navigation systems and robotic techniques could potentially solve problems of imprecision in traditional total knee arthroplasty. It is expected that the success rate and longevity of total knee arthroplasty will be improved during the twenty first century.

안내각췌피는 안륜근의 검판전부 및 격막전부의 조기 하방 부착이 근본적인 원인이며, 과다한 피부는 이들 근육이상에 수반되는 이차적인 현상이라고 생각된다. 이의 교정을 위해서는 과도피부의 절제와 안륜근의 절제를 동시에 시행하여, 수술 후 반흔형성을 피하고, 눈의 미용적인 개선도 동시에 가져 올 수 있었다.

The subtalar joint is a complex joint that is functionally responsible for inversion and eversion of the hindfoot. Advances in optical technology and surgical instrumentation have allowed the arthorscocpic surgeon to investiagate the small joints including the subtalar joint. Indications for subtalar arthroscopy include pain, swelling, stiffness and locking. Therapeutic indications include treatment of chondromalacia, osteophytes, arthrofibrosis, synovitis, loose bodies, osteochondral lesions, excision of a painful os trigonum, arthrodesis, and FHL tendinopathy. Contraindications to subtalar arthroscopy include infection, advanced osteoarthritis with deformity, severe edema, poor vascularity and poor skin quality. Subtalar arthroscopy is a technically demanding and difficult procedure that should only be performed by experienced surgeons. With proper instrumentation and careful operative techniques, satisfactory results may be obtained with minimal morbidity.

Argon laser used in this case report, is special in having two wavelength of 488, 514nm blue-green visible light spectrum. Blue light is used for composite resin polymerization and caries detection. Green light is used for soft tissue surgery and coagulation. Maximum absorption of this laser light occurs in red pigmentation such as hemoglobin. The argon laser may be well-suited for selective destruction of blood clots and hemangioma with minimal damage to adjacent tissues. Argon laser light penetrates tissue to the 1 mm depth, so its thermal intensity is lower than $CO_2$ laser light. Also, due to its short wavelength it can be focused in a small spot and even single gene can be excised by this laser and microscopy. After applicating argon laser to 4 patient for surgical procedure and to 1 patient for curing the composite resin, following results were obtained. 1. Improved visibility were gained due to hemostasis and no specific technique were needed according to easy recontouring of the tissue. 2. Ability to use by contact mode, tactile sense was superior but tissue dragability and accumulation of tissue on the tip needed sweeping motion. 3. Additive local anesthetic procedure was needed. 4. No suture and less curing time reduced chair time, this made argon laser available in pediatric dentistry.

Free TRAM flap is now increasingly suggested to patients requiring breast reconstruction after the mastectomy. This study is to introduce the experiences of bilateral free TRAM flaps for reconstruction of bilateral breasts and to suggest the way of getting the more satisfactory results. A total of 6 breasts were reconstructed in 3 patients using bilateral free TRAM flaps immediately following the mastectomy. Average operative time for bilateral breast reconstruction was 8 hours comparing to 6.5 hours for unilateral breast reconstruction. Partial or total flap loss did not occur in 6 flaps. Abdomen was repaired directly with muscle and fascia sparing technique without necessity of mesh graft. There was no complication in donor site like abdominal hernia. Bilateral breast reconstruction can achieve exceptionally good aesthetic result with low complication if it is performed with skillful technique and experience. The reason for this is that fairly good symmetry usually is obtained in the initial surgery and in most cases only minimal additional surgery is required to achieve a satisfactory aesthetic result. The one disadvantage of bilateral reconstruction with autologous tissue is the length of the surgical procedure. Although the initial bilateral breast reconstruction can be a long, tedious procedure if free flaps are used, it must be a valuable treatment option for bilaterally mastectomized patients.

Background: The patients of facial hyperhidrosis have been known that they had much difficulties in interpersonal relationships and social activities due to excessive hidrosis when they were in stress, hot weather, or having meals. Previous drug therapy and stellate ganglion block have only temporary effects. The surgical method, $T_1$ sympathetomy has the risk of Hornor's syndrome. For that reasons, the sympathicotomy of proximal and distal portions of $T_2$ sympathetic ganglion with electroresectoscope used in transurethral resection seemed to be appropriate procedure, and we would like to report the results of our procedure. Method: Under the general anesthesia with semi-sitting position, and the portal was made through the small incision along the upper border of the 4th rib at the crossing point of mid-axillary line. After the partial collapse of lung by insufflation of 300 to 500 ml of $CO_2$, $T_2$ sympathetic ganglion was identified and resected proximally and distally with electro-cauterization. Finally the lung was expanded by limiting flow until the airway pressure reached 30 to 40 cm$H_2O$, and the wound was closed after removal of electroresectoscope. Result: There was no postoperative complication requiring surgical interventions. The facial sweating was stopped immediately after the operation and all the patients appeared to be satisfied. Conclusion: $T_2$ sympathicotomy with TUR electroresectoscope is thought be the minimal invasive and highly successful method in the treatment of facial hyperhidrosis. But longer terms follow-up will be needed to prove this result.
