Background Volar plate avulsion fracture of the proximal interphalangeal (PIP) joint is one of the most common hand injuries. In this study, we divided patients into two groups: patients with pure volar plate avulsion fracture, and patients with volar plate avulsion fracture concomitant with collateral ligament rupture. The purpose of this study was to compare long-term surgical outcomes between the two groups. As a secondary measure, the Mitek bone anchoring and polydioxanone (PDS) bone suturing techniques were compared. Methods A single-institutional retrospective review of the surgical treatment of volar plate avulsion fracture was performed. The cases were divided into those with pure volar plate avulsion fracture (group A, n=15) and those with volar plate avulsion fracture concomitant with collateral ligament rupture (group B, n=15). Both groups underwent volar plate reattachment using Mitek bone anchoring or PDS bone suturing followed by 2 weeks of immobilization in a dorsal protective splint. Results The average range of motion of the PIP joint and extension lag were significantly more favorable in group A (P<0.05). Differences in age; follow-up period; flexion function; visual analog scale scores; disabilities of the arm, shoulder, and hand scores; and the grip strength ratio between the two groups were non-significant. No significant differences were found in the surgical outcomes of Mitek bone anchoring and PDS bone suturing in group A. Conclusions Overall, the surgical outcomes of volar plate reattachment were successful irrespective of whether the collateral ligaments were torn. However, greater extension lag was observed in cases of collateral ligament injury.

Background Excessive bleeding is one of the most severe complications of orthognathic surgery (OGS). This study investigated the associations of intraoperative blood loss and surgical time with the direction of maxillary movement. Methods This retrospective study involved patients who underwent OGS from October 2017 to February 2020. They were classified based on whether maxillary setback was performed into groups A1 and B1, respectively. Relative blood loss (RBL, %) was used as an indicator to compare intraoperative blood loss between the two groups. The surgical time of the two groups was also measured. Subsequently, the patients were reclassified based on whether posterior impaction of the maxilla was performed into groups A2 and B2, respectively. RBL and surgical time were measured in the two groups. Simple linear and multiple regression analyses were performed. P-values <0.05 were considered to indicate statistical significance. Results Eighteen patients were included. The RBL and surgical time for the groups were: A1, 13.15%±5.99% and 194.37±42.04 minutes; B1, 12.41%±1.89% and 196.50±46.07 minutes; A2, 13.94%±3.82% and 201.00±39.70 minutes; and B2, 9.61%±3.27% and 188.84±38.63 minutes, respectively. Only RBL showed a statistically significant difference between the two groups (A2 and B2, P=0.04). Conclusions Unlike maxillary setback, posterior impaction of the maxilla showed a significant association with RBL during surgery. When performing posterior impaction of the maxilla, clinicians need to pay particular attention to surgery and postoperative care.

Background Many difficulties exist in establishing a treatment plan for slow-flow vascular malformation (SFVM). In particular, little research has been conducted on the surgical treatment of SFVMs. Thus, we investigated what proportion of SFVM patients were candidates for surgical treatment in clinical practice and how useful surgical treatment was in those patients. Methods This study included 109 SFVM patients who received care at the authors' clinic from 2007 to 2015. We classified the patients as operable or non-operable, and analyzed whether the operability and the extent of the excision varied according to the subtype and location of the SFVM. Additionally, we investigated complications and self-assessed satisfaction scores. Results Of the 109 SFVM patients, 59 (54%) were operable, while 50 (46%) were non-operable. Total excision could be performed in 44% of the operable SFVM patients. Lymphatic malformations were frequently non-operable, while capillary malformations were relatively operable (P=0.042). Total excision of venous malformations could generally be performed, while lymphatic malformations and combined vascular malformations generally could only undergo partial excision (P=0.048). Complications occurred in 11% of the SFVM patients who underwent surgery; these were minor complications, except for 1 case. The average overall satisfaction score was 4.19 out of 5. Conclusions Based on many years of experience, we found that approximately half (54%) of SFVM patients were able to undergo surgery, and around half (44%) of those patients were able to fully recover after a total excision. Among the patients who underwent surgical treatment, high satisfaction was found overall and relatively few complications were reported.

Purpose: Many researches about various surgical method for blepharoptosis have already been introduced. But researches for complications after blepharoptosis correction is relatively insufficient. So, this study was performed to recognize common complications that arised depending on the severity of blepharoptosis, levator function and surgical method. Methods: 250 patients who have underwent surgical treatment for blepharoptosis from 1987 to 2006 were employed in this study. Patients were categorized by severity of blepharoptosis, levator function and surgical method that has been used. Complications after blepharoptosis correction were analyzed. Result: Total of 64 patients had occurred complications, the specifics are as following; undercorrection 22, asymmetry 13, overcorrection 12, lagophthalmos 4, abnormal eyelid contour 4, exposure keratitis 3, ectropion 2, inclusion cyst 2, infection 1 and conjunctival prolapse 1. Among above patients, 3 patients had two kinds of complications. 21 patients was underwent secondary surgery due to complication. Conclusion: Evaluating the outcomes of the secondary surgery, the early correction was better than the late correction. The most of the complications were recovered through conservative and surgical treatments. The most of the complications (47 patients) were undercorrection, asymmetry, overcorrection and took 73.4% of the total complications. The more severe the blepharoptosis and the more poor the levator function, the rate of complications were higher. According to the operation methods, most complications were occurred in levator operation, frontalis transfer and OOM flap.

Background Oncoplastic surgery is being increasingly performed in Korean women; however, unlike Westerners, Korean women usually have small to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors should be considered to determine the optimal surgical method. Methods A total of 108 patients who underwent oncoplastic surgery from January 2013 to December 2016 were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD) flap transposition, and reduction oncoplasty, to restore the breast volume and symmetry. Results The mean weight of the tumor specimens was 40.46 g, and the ratio of the tumor specimen weight to breast volume was 0.12 g/mL in the patients who underwent glandular tissue reshaping (n=59). The corresponding values were 101.47 g and 0.14 g/mL, respectively, in the patients who underwent reduction oncoplasty (n=17), and 82.54 g and 0.20 g/mL, respectively, in those treated with an LD flap (n=32). Glandular tissue reshaping was mostly performed in the upper outer quadrant, and LD flap transposition was mostly performed in the lower inner quadrant. No major complications were noted. Most patients were satisfied with the aesthetic results. Conclusions We report satisfactory outcomes of oncoplastic surgical procedures in Korean patients. The results regarding specimen weight and the tumor-to-breast ratio of Asian patients will be a helpful reference point for determining the most appropriate oncoplastic surgical technique.

Background Congenital muscular torticollis (CMT) is characterized by persistent head tilt toward the affected side. No consensus exists regarding the cause of this disorder. In this study, we analyzed various clinical factors in patients with CMT who were treated with surgical release. This analysis enabled us to identify potential causative factors of CMT and to establish a basis for surgical interventions. Methods In total, 584 patients who underwent surgical intervention for CMT from October 2007 to December 2016 were included in this study. Their demographic characteristics, birthrelated factors, and clinical features were analyzed. Results Data from 525 patients were analyzed in this study after exclusion of those with insufficient information. Before birth, 31 patients (5.9%) were diagnosed with oligohydramnios, and 87 (16.6%) had a breech presentation. Seven (1.3%) cases of clavicle fracture and two (0.4%) cases of cephalohematoma were noted at birth. Before surgery, 397 patients (75.6%) underwent physiotherapy and 128 patients (24.4%) did not. The duration of physiotherapy ranged from 1 to 50 months (average, 6 months). Conclusions Our study shows that 16.6% of the CMT patients presented in the breech position, which is a much higher rate than that observed in the general population (3%-4%). We hypothesize that being in the breech position as a fetus appears to exert a significant influence on shortening and fibrosis of the sternocleidomastoid muscle.

Purpose: The goal of cancer surgery is complete removal of cancer tissue and prevention of recurrence. Surgeons can change the surgical instruments after total resection of the cancer mass. The purpose of this procedure is to prevent dissemination of the cancer cells attached to the surgical instruments. Authors hypothesize the possibility of local recurrence caused by the cancer cells attached to the surgical instruments in the skin cancer cases. Methods: Skin cancers were induced by using DMBA-TPA two-stage carcinogenesis model in 10 of Balb/c mice. In 2-weeks, skin cancer was developed in all 10 mice. cancer cell attached surgical instruments were made by pinching the removed cancer tissue using Adson tissue forcep 10, 20, 30 times each. To count number of cancer cells in each forcep with different number of pinching was done, the forceps were washed in 30 mL of the normal saline and Cytospin preparation was done. To make recurrence models from cancer cell attached surgical instrument, three incisions were made in normal skin of each mouse, and local seeding was done by pinching subcutaneous tissue in 10, 20, 30 times each by using Adson teeth forceps mentioned above as cancer cell attached surgical instrument. Results: All skin cancers were squamous cell carcinoma. Local recurrences were developed in 7 mice (3 in 10 times forceping site, 2 in 20 times forceping and 3 in 30 times forceping). In the cytospin test, the mean number of squamous cells in 100 microscope was 28.6 in 10 times, 47.2 in 20 times, 93.6 in 30 times, respectively. P value was 0.002 in Wilcoxon-Sign test. Conclusion: The number of cell count was significantly increased as number of pinching was increased. And these cells are able to induce local recurrence by local seeding. Considering this result, authors are able to confirm that the minimal handling in cancer surgery is important factor to prevent local recurrence.

Rhinophyma is a painless benign tumor of the skin of the nose. It is the most severe form of rosacea. Rhinophyma is particularly rare among Asians. It can be treated with surgical resection using various methods, including scalpel excision, dermabrasion, cryosurgery, argon laser, carbon dioxide laser, and electrocautery. However, the gold standard treatment of rhinophyma remains unknown. In the present case, we debulked a giant rhinophyma with a scalpel and contoured it using a bur. Along with a relevant literature review, we present a case of rhinophyma in an Asian patient who was treated at no additional cost using a bur widely used in general plastic surgery.

A keratoacanthoma is a rapidly growing cutaneous tumor that spontaneously involutes in most instances. A giant keratoacanthoma is a rare variant and are characterized by lesions larger than 20 mm in diameter. We report a 56-year-old man with a rapidly growing tumor of the right cheek, which was diagnosed as keratoacanthoma. The mass was excised completely under general anesthesia, followed by Limberg flap for reconstruction. Intraoperative frozen section histology suggested the lesion to be a well-differentiated squamous cell carcinoma, whereas final histopathology was consistent with keratoacanthoma. We herein report the first case of a giant keratoacanthoma treated with surgical excision in Korea and discuss the clinical and histopathological features of keratoacanthoma, with a review of the literature.

Lymphedema is a frequent complication after the treatment of various cancers, particularly breast cancer, gynecological cancers, melanomas, and other skin and urological cancers. Lymphedema patients have chronic swelling of the affected extremity, recurrent infections, limited mobility and decreased quality of life. Once lymphedema develops, it is usually progressive. Over time, lymphedema leads to fat deposition and subsequent fibrosis of the surrounding tissues. However, there is no cure for lymphedema. Recently, the development of microsurgery has led to introduction of new surgical techniques for lymphedema, such as vascularized lymph node transfer. We report here the latest trends in the surgical treatment of lymphedema, as well as diagnosis and conventional treatments of lymphedema.
