Since G.N. Hounsfield's clinical use of computed tomography in 1971, digital imaging technique using computers has shown an eye opening progress. Progress has made 3-dimensional understanding of not only facial bones but muscles and other connective tissues possible through 3-dimensional reconstruction of preexisting tomographical images. Also, quantitative analysis of density, distance, volume has become possible, allowing objective analysis of preoperative and postoperative states through imaging. The authors measured the masseter muscle volume of 20 normal individuals and 8 female patients through 3-D reconstructive CT imaging and made a statistical analysis of the measurements. The method used in our study may be applied to the diagnosis of disease causing the change of the facial volume and presurgical design as a useful tool to provide objective information on the evaluation of surgery outcome.

Purpose: Lateral osteotomy is an essential step in the correction of nasal bony asymmetry. Direct visualization allows accurate repositioning of the nasal bones compared to blind techniques, which require precision and manual dexterity. We propose direct visualization procedures in open corrective rhinoplasty. Methods: The technique was used on 16 patients. All patients underwent open rhinoplasty with a columellar incision. The marginal incisions were extended on either side to allow access to the piriform aperture. A double hook was used to caudally retract the lower lateral cartilages and the fibrous connections between the upper and lower lateral cartilages were released until the piriform aperture was visualized. Through the incision, lateral osteotomy was performed using a reciprocating saw at that time with direct visualization. Additional procedures including augmentation rhinoplasty, hump resection, septoplasty and tip plasty were performed simultaneously. Results: This method provided excellent exposure to the lateral nasal bones and allowed the lateral osteotomy to be carried out precisely using the reciprocating saw. Conclusion: This extended open rhinoplasty method is suitable for most individuals, allowing a wide surgical field.

Purpose: Pleomorphic adenoma is the most common benign neoplasm in parotid gland. Superficial parotidectomy was usually used to remove the pleomorphic adenoma. But, this method has to remove tumor with normal parotid tissue. Authors did lumpectomy to remove pleomorphic adenoma in parotid gland, because pleomorphic adenoma is wrapped in a capsule as it grows. The purpose of this study is to evaluate the efficacy of lumpectomy as a treatment of pleomorphic adenoma in parotid gland. Method: From 2002 to 2008, 8 patients underwent the lumpectomy of the pleomorphic adenoma in parotid gland. Occurrence of the complications and recurrance were evaluated. Result: Patients were followed-up for a mean 45 months. There were no recurrance or no complication after lumpectomy. Conclusion: Authors suggest that the lumpectomy lead to decrese complications, recurrane and can be used as a procedure for the resection of pleomorphic adenoma in parotid gland.

Background: The free flap surgical method is useful for the reconstruction of head and neck defects. This study retrospectively analyzed the results of head and neck reconstructions using various types of free flaps over the past 30 years. Methods: Between 1989 and 2018, a total of 866 free flap procedures were performed on 859 patients with head and neck defects, including 7 double free flaps. The causes of vascular crisis and salvage rate were analyzed, and the total flap survival rate calculated among these patients. Additionally, the survival and complication rates for each flap type were compared. Results: The 866 cases included 557 radial forearm flaps, 200 anterolateral thigh flaps, 39 fibular osteocutaneous flaps, and 70 of various other flaps. The incidence of the vascular crisis was 5.1%; its most common cause was venous thrombosis (52.3%). Salvage surgery was successful in 52.3% of patients, and the total flap survival rate was 97.6%. The success rate of the radial forearm flap was higher than of the anterolateral flap (p< 0.01), and the primary sites of malignancy were the tongue, tonsils, and hypopharynx, respectively. Conclusion: The free flap technique is the most reliable method for head and neck reconstruction; however, the radial forearm free flap showed the highest success rate (98.9%). In patients with malignancy, flap failure was more common in the anterolateral thigh (5.5%) and fibular (5.1%) flaps.

Venovenous (VV) extracorporeal membrane oxygenation (ECMO) is a lifesaving technique for patients experiencing respiratory failure. When VV ECMO fails to provide adequate support despite optimal settings, alternative strategies may be employed. One option is to add another venous cannula to increase venous drainage, while another is to insert an additional arterial return cannula to assist cardiac function. Alternatively, a separate ECMO circuit can be implemented to function in parallel with the existing circuit. We present a case in which the parallel ECMO method was used in a 63-year-old man with respiratory failure due to coronavirus disease 2019, combined with cardiac dysfunction. We installed an additional venoarterial ECMO circuit alongside the existing VV ECMO circuit and successfully weaned the patient from both types of ECMO. In this report, we share our experience and discuss this method.

The purpose of this study was to investigate the causal relationships of need, self-esteem, body satisfaction on aesthetic surgery attitude of female. The method of the study was survey research by using questionnaires. Subjects were 813 females of 10's to 40's living in Daejeon Metropolitan City and Gongju City, Chungchungnamdo. Statistical analysis methods were one-way ANOVA. Duncan's multiple range test, Pearson's correlation coefficient, and multiple regression analysis. The results of the study were as follows. Women with lower body satisfaction and self-esteem had a tendency to keep the secret of aesthetic surgery. Women in higher social class and having higher need for dominance showed also strong tendency to keep the secret of aesthetic surgery. Women with lower body satisfaction and having higher needs for achievement and exhibition appreciated the value of aesthetic surgery more. Women with lower body satisfaction and self-esteem but with higher need for exhibition and dominance were more willing to confirm the aesthetic surgery Women with higher need for dominance but with lower self-esteem and body satisfaction were more willing to undergo aesthetic surgery in spite of high cost of surgery. Women having lower self-esteem, lower need for achievement, and lower body satisfaction were more willing to admit the risk tolerance of aesthetic surgery. As a conclusion, need, self-esteem, and body satisfaction constituted important characteristics which could affect aesthetic surgery attitude directly. Women having higher need were more willing to admit the change of body shape via aesthetic surgery.

Organ preservation surgery and minimally invasive surgery have been developed during the past 20 years with major focus on transoral laser surgery, endoscopic surgery, and robotic surgery. Two major robotic surgeries in head and neck area are transoral robotic surgery (TORS) and robotic thyroidectomy. Transoral robotic surgery is a safe and efficacious method of surgical treatment of oropharyngeal. hypopharyngeal and laryngeal neoplasm. Advantages of the technique include adequate ability to visualize and manipulate lesions with two hands. TORS can provide magnified three dimensional views and overcome the limitation resulting from the "line of sight" which hinders transoral laser procedure. The swallowing function following transoral robotic surgery show superior and patients were able to retain or rapidly regain swallowing function in the majority of cases. Recently, robotic thyroidectomy has also been developed to overcome the [imitation of endoscopic thyroidectomy. Robotic thyroidectomy by a gasless unilateral axillo-breast or axillary approach using a da Vinci S Surgical Robot is a feasible and cosmetically excellent procedure. It can be a promising alternative to endoscopic thyroidectomy or conventional open thyroidectomy.

Purpose: The purpose of this study was to explore the illness experiences of patients who had spinal surgery. Methods: Colaizzi's phenomenological method was used for the data analysis. Patients who had spinal surgery were included in this study. The data was collected between April and October 2022 by conducting a one-on-one, in-depth interview. Results: Five theme clusters were identified based on the illness experiences of patients who had spinal surgery: "An agonizing life changed by pain", "Efforts to alleviate the pain", "Surgery was determined to be the best way to relieve pain", "Recovered daily life after relieving pain caused by surgery", and "Dedicated to living a healthy, pain-free life". The analysis further yielded 20 themes. Patients used various treatment methods to relieve pain, but ultimately chose surgery due to unbearable pain. Patients who had spinal surgery felt grateful that they were feeling good and healthy because they could return to their normal daily lives. After all, the pain was relieved after the surgery. Even though some pain remained unrelieved, the patients had the hope of getting better through exercise and rehabilitation. Conclusion: This study provides an in-depth understanding and meaning of the illness experiences of patients who had spinal surgery and presents new perspectives on clinical practice. The findings of this study are expected to be useful in developing and applying systematic and customized nursing interventions before and after spinal surgery.

Purpose: The zygoma is a key element which composes the facial contour. Zygomatic fracture induces facial asymmetry. We use radiologic evaluation or inspections mainly for identification of symmetry after reduction depressed zygomatic fracture. But the disadvantages of such methods are time-consuming and complicated process. So we tried to develop a new testing method with a ruler and a level. Methods: In unilateral depressed zygomatic fracture patient, parallel to the patient's head to make sure lay horizontaly. Put the leg of a ruler on the malar eminence so that it is at the same distance from the facial midline. Then take the level of malar eminence as put the level above the ruler. This process was performed before and after the reduction. Results: We were able to fix with plate and screw after checking the results of reduction fast and easily. Good results were obtained at post-operative radiologic evaluation. Conclusion: We can easily get the ruler and level around life. This method is not only simple but also shorttime process compared with other method-radiologic evaluation or inspection. And the operator can explain the results to the patients easily and objectively. Authors obtained the good results with this new method, and would introduce it for another method of identifying the result of reduction in depressed zygomatic fractures.

Purpose: Traumatic telecanthus can result from nasoethmoid-orbital fractures. Repair of the medial canthal tendon (MCT) using transnasal wiring is regarded as a choice of method to treat telecanthus, however, is often complicated by incomplete anchoring and drift of canthus, extrusion of wire, in-fracture of orbital bone, and eye damage. The authors introduced oblique transnasal wiring method through the Hiraga's epicanthopalsty incision instead of well-known classical bicoronal approach. Methods: Five patients with traumatic telecanthus were treated with this method. Though the Hiraga's epicanthoplasty incision, we could approach the operative field; the medial orbital wall and detached MCT. Oblique transnasal wiring was performed as following steps. After slit skin incision on the contralateral nasal recession area, drill holes were made from this point to the superior and posterior point of lacrimal sac of deformed eye. A 2-0 wire was double-passed through the holes and MCT. Traction was applied to ensure pulling the MCT and the wires were twisted in the contralateral nose, securing the MCT in the correct position. Results: All patients except 1 person showed improvement and rapid recovery. On average each canthus was moved 5.6 mm medially. In all cases, there were no eyelashes disappear, lacrimal canaliculitis, lacrimal duct injury, or infections. Conclusion: The Hiraga's epicanthoplasty incision could give sufficient operative field to reattach the MCT in traumatic telecanthus patients. And the oblique transnasal wiring technique is effective for the Asians who have flat nose and exophthalmic eye. The authors conclude that this technique could be a simple, safe and scarless method to correct traumatic telecanthus.
