Background The extended latissimus dorsi flap is important for breast reconstruction. Unfortunately, donor site seroma is the most common complication of extended latissimus dorsi flap for breast reconstruction. Although using fibrin sealant in the donor site reduces the rate of seroma formation, donor site seroma remains a troublesome complication. The purpose of this study was to analyze the effectiveness of the combination of quilting sutures and fibrin sealant in the latissimus dorsi donor site for the prevention of seroma. Methods Forty-six patients who underwent breast reconstruction with extended latissimus flap were enrolled in the study. The patients received either fibrin sealant (group 1, n=25) or a combination of fibrin sealant and quilting sutures (group 2, n=21) in the extended latissimus dorsi donor site. Outcome measures were obtained from the incidence, volume of postoperative seroma, total drainage amount, indwelling period of drainage, and duration of hospital stay. Results The incidence of seroma was 76% in group 1 and 42.9% in group 2 (P=0.022). We also found significant reductions in seroma volume (P=0.043), total drainage amount (P=0.002), indwelling period of drainage (P=0.01), and frequency of aspiration (P=0.043). The quilting sutures did not affect the rate of drainage, tube reinsertion, or hospital stay. Conclusions The use of quilting sutures combined with fibrin sealant on the latissimus dorsi flap donor site is helpful for reducing the overall seroma volume, frequency of aspiration, and total drainage amount.

Background Zygomaticomaxillary complex (ZMC) fractures mostly occur in the form of tripod fractures. The surgical field is accessed using a combination of three classic approaches. However, the subciliary incision may have unfavorable aesthetic results. Herein, the authors report the advantages of the extended transconjunctival approach (ETA) combined with T-bar screw reduction in minimizing scarring and complications for the treatment of ZMC fractures. Methods A total of 26 patients underwent ZMC reduction through the ETA and intraoral approach. A skin incision measuring roughly 5 to 8 mm in length was placed following the lateral canthal skin crease. After releasing the inferior crus of the lateral canthal tendon for canthotomy, the medial periosteum of the lateral orbital rim was preserved for canthal reattachment. A limited subperiosteal dissection and partial relaxing incision of the orbicularis oculi were performed to expose the fracture line of the inferior orbital rim and zygomaticofrontal suture. Reduction was performed using a T-bar screw through the transconjunctival incision and an elevator through the intraoral incision. Results The aesthetic and functional results were excellent. Successful reduction was achieved and the skin incision was less than 8 mm in 20 cases (76.9%). Only six patients had an additional skin incision (less than 5 mm) to achieve reduction. No cases of ectropion, entropion, or excessive scarring were noted. Conclusions The ETA using a T-bar screw is a useful method for maximizing aesthetic results in ZMC fractures, with the advantages of minimal scarring, faster recovery, and maintenance of pretarsal fullness.

A lipomatous lesion of the cord is an accidentally encountered structure during the operative repair of inguinal hernia. This lesion has been reported as a lipoma of the cord in adults. However, there is only a limited number of reports in the pediatric age group. To evaluate the prevalence of this lesion in children and in order to review the surgical signiticancies, 600 hernia operations in 411 children during a period of 4 years from January, 2000 to December, 2003 in the Division of Pediatric Surgery, Department of Surgery, the Catholic University of Korea, were included in this study. There was a total of 31 (5.2 %) lipomatous lesions in 25 (6.1 %) cases; 3 cases in infants, 17 between 1 to 4 years, and 5 above 5 years of age. Male was more prevalent (male to female ratio 14:11). The laterality of clinical hernia with the lesions was 10 in the right, 13 in the left and 2 in both sides. The patients with ipsilateral lesions to the hernia were 14, contralateral in 5 and bilateral in 6 cases. Excluding 1 case of bilateral lesions in bilateral hernia, 10 lesions were contralateral to the clinical hernias. In 1 case, lipomatous lesion was the sole finding with nonsignificant patent processus vaginalis. Every lesion was suture ligated and resected with gentle traction of the dissected hernia sac. It has not been clearly defined whether the lesion is a stopper or a provocator of the hernia development. However, removal is highly recommended to make a differential diagnosis from the recurrent inguinal hernia in future. The term "lipomatous lesion" seems to be pathologically accurate and must be differentiate from the true lipomas.

Purpose: Epidermoid cyst may be congenital or acquired. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Traumatic epidermoid cysts are rare tumors occurring on the nasal tip, especially resulting aesthetic procedure. So, we report a rare case of an iatrogenic epidermoid cyst in the nasal tip following rhinoplasty. Methods: A 44 - years old man had undergone rhinoplasty for several times. First time, the previous augmentation rhinoplasty and wedge osteotomy were performed nineteen months ago, lastly implant removal and unknown filler injection were performed one year ago at another local clinic. He had induration and tenderness on nasal tip and dorsum continued for 3 months. We thought that it caused by foreign body reaction with residual alloderm in nose. For removal of residual alloplastic material, open approach using transcolumellar incision was done. But, incidentally we found cystic mass on the nasal tip. Results: The findings were of an $0.8{\times}0.5{\times}0.5cm$ sized round cystic mass containing cream coloured material with a thick cheese - like consistency. The mass was completely excised and submitted for histology. This confirmed the diagnosis of an epidermoid cyst lined by keratinizing squamous epithelium. There was no induration, tenderness and sign of recurrence after excision of the mass. Conclusion: Epidermal cyst of the nasal tip region represents an unusual clinical lesion and it presents as foreign body reaction. And then, our case demonstrates that meticulous surgical approach and suture technique are the keys to prevention against iatrogenic nasal epidermoid cyst, especially in secondary rhinoplasty.

Background Implant malposition can produce unsatisfactory aesthetic results after breast augmentation. The goal of this article is to identify aspects of the preoperative surgical planning and intraoperative flap fixation that can prevent implant malposition. Methods This study examined 36 patients who underwent primary dual plane breast augmentation through an inframammary incision between September 1, 2012 and January 31, 2013. Before the surgery, preoperative evaluation and design using the Randquist formula were performed. Each patient was evaluated retrospectively for nipple position relative to the breast implant and breast contour, using standardized preoperative and postoperative photographs. The average follow-up period was 10 months. Results Seven of 72 breasts were identified as having implant malposition. These malpositions were divided into two groups. In relation to the new breast mound, six breasts had an inferiorly positioned and one breast had a superiorly positioned nipple-areolar complex. Two of these seven breasts were accompanied with an unsatisfactory breast contour. Conclusions We identified two main causes of implant malposition after inframammary augmentation mammaplasty. One cause was an incorrect preoperatively designed nipple to inframammary fold (N-IMF) distance. The breast skin and parenchyma quality, such as an extremely tight envelope, should be considered. If an extremely tight envelope is found, the preoperatively designed new N-IMF distance should be increased. The other main cause of malposition is failure of the fascial suture from Scarpa's fascia to the perichondrium through an inframammary incision. As well, when this fixation is performed, it should be performed directly downward to the perichondrium, rather than slanted in a cranial or caudal direction.

Background Non-incisional blepharoplasty is a simple, less invasive method for creating a more natural-appearing double eyelid than classical incisional blepharoplasty. However, in aging patients, non-incisional blepharoplasty is not effective due to more severe blepharochalasis. Traditionally, incisional blepharoplasty is a common surgical method used for older patients, but blepharoplasty in elderly patients typically results in prolonged recovery times, and final blepharoplasty lines may be located in unintended or asymmetrical positions. Here, we introduce a new modified combination technique for geriatric blepharoplasty. Methods A total of ten patients were treated from July 2010 through July 2012 using the combination method. First, we performed non-incisional blepharoplasty using tarsodermal fixation. Then, incisional blepharoplasty with additional elliptical excision of the upper eyelid skin was performed. We removed pretarsal tissue, fat, the orbicularis oculi muscle, and orbital fat. Telephone surveys were administered to all patients for follow-up. The questionnaire was composed of eight questions that addressed recurrence and satisfaction with aesthetics and the procedure. Results A total of nine patients (90%) responded to the telephone survey. All cases of moderate to severe blepharochalasia were corrected and there were no major complications. Patients who underwent blepharoplasty had higher satisfaction scores. All patients were satisfied with the postoperative shapes of their eyelids. Conclusions The advantages of the proposed technique include: ease of obtaining a natural-looking fold with symmetry at the desired point; reproducible methods that require short operation times; fast postoperative recovery that results in a natural-appearing double-eyelid line; and high patient satisfaction.

The aortic inclusion technique is frequently used in the original Bentall's procedure for the control of excessive postoperative bleeding. Although this procedure has improved the outcome of patients with aortic root disease, there is a high incidence of both early and late complications, including coronary artery stenosis, kinking or pseudoaneurysm formation at the coronary suture lines. Pseudoaneurysm of the ascending aorta is a relatively rare, but fatal complication, which occurs after wrap-inclusion composite graft replacement. Herein, the case of a 45-year-old female, who developed a perigraft aortic pseudoaneurysm 10 years after a Bentall's procedure (wrap-inclusion technique), but was successfully managed using the Cabrol's method, is reported.

Objectives: This study aimed to validate the effectiveness of a recently proposed difficulty index for removal of impacted mandibular third molars based on extraction time and suggest a modified difficulty index including the presence of pathologic conditions associated with third molars. Materials and Methods: This retrospective study enrolled 65 male patients younger than 25 years with third molars. Extraction time was calculated from start of the incision to the last suture. The difficulty scores for third molars were based on spatial relationship (1-5 points), depth (1-4 points), and ramus relationship (1-3 points) using cone-beam computed tomography. The difficulty index was defined as follows: I (3-4 points), II (5-7 points), III (8-10 points), and IV (11-12 points). The modified difficulty score was calculated by adding one point to the difficulty score if the third molar was associated with a pathologic condition. Two modified difficulty indices, based on the presence of pathologic conditions, were as follows: the half-level up difficulty index (HDI) and the one-level up difficulty index (ODI) from the recently proposed difficulty index. Results: The correlations between extraction time and difficulty index and or modified difficulty indices were significant (P<0.001). The correlation coefficient between extraction time and difficulty index was 0.584. The correlation coefficients between extraction time and HDI and ODI were 0.728 and 0.764, respectively. Conclusion: Extraction time of impacted third molars exhibited a moderate correlation with difficulty index and was strongly correlated with the modified indices. Considering the clinical implications, the difficulty index of surgical extraction should take into consideration the pathologic conditions associated with third molars.

This study was undertaken to investigate the effect of cingulate cortical ablation upon gastric ulceration, and the pathway through which cingulate cortex exerts the effect. 56 female rats were divided equally into cingulate (cingulate cortical ablation), cingulate-vagal (cingulate cortical ablation and vagotomy), normal control and vagal (vagotomy) groups. Cingulate cortex was ablated through a slit-shaped opening (1 mm in width, 13 mm in length) which was made symmetrically on both sides of, and parallel to, the sagittal suture by removing a bone flap from parietal and frontal bones on each side. Vagus nerves on both sides were transected around the distal end of the esophagus. In the normal control animals, surgical intervention ended with scalp incision. All rats were kept without restraint or food deprivation for 3 weeks after surgery. The stomach of each rat was inflated with 7 ml of physiological saline and then removed under deep anesthesia. The mucosal surface was examined under dissecting microscope for the location, shape and number of ulcers, and then enlarged photograph $(4{\times})$was taken. The incidence of ulcer in each group was counted and the number of ulceration as well as the total area of glandular mucosa were measured on the photograph. Results obtained were as follows: 1. The mean number of ulcer per stomach and the total area of ulcer exprssed as permillage of the total area of glandular mucosa were significantly higher in the cingulate group than the cingulate-vagal, the normal control and the vagal groups. There was no difference among the latter three groups. 2. The incidence of ulcer in the cingulate group was significantly higher than that in the .normal control group and was also higher, though not significantly, than those in the cingulate-vagal and the vagal groups. There was no difference among the normal control, the cingulate-vagal and the vagal groups. It is inferred from the above results that the cingulate cortex exerts an inhibitory influence upon gastric ulceration and that this influence is mediated by controlling the vagal activity.

Purpose: The forehead flap is the workhorse in nasal reconstruction, which provides a similar skin color, texture, structure, and reliability. There are some disadvantages, including donor site morbidities, 2- or 3-stage operations, and postoperative management after initial flap transfer. Furthermore, there has been little attention to the exposed raw surface wound, after the first stage of an operation. This article describes the authors' modification to overcome this problem, using artificial collagen membrane. Methods: An Artificial collagen membrane is composed of an outer silicone membrane and an inner collagen layer. After a forehead flap elevation, the expected raw surface was covered by an artificial collagen membrane with 5-0 nylon suture. A simple dressing, which had been applied to the site, was changed every 2 or 3 days in an outpatient unit. At 3 weeks postprocedure, a second stage operation was performed. Results: With biosynthetic protection of the raw surface, there were no wound problems, such as infection or flap loss. Thus, the patient was satisfied due to an effortless management of the wound and a reduction in pain. Conclusion: The application of an artificial collagen membrane to the raw under-surface of the flap could be a comfortable and a protective choice for this procedure.
