Aplasia cutis congenita represents a congenital absence of all skin layers, and it may occasionally extend through the bone and dura of the skull. Since the first report was described in the extremity by Cordon 1767, and Campbell 1826, approximately over 500 cases have been reported. About eighty five percents of all cases are found in the scalp, with 15 to 30 percents involving the skull as well. Fifteen percents of all cases involve nonscalp locations and are often bilateral symmetrical. It has been relatively rarely reported disorder abroad as well as domestically. It has several clinical subtypes classified by the location and pattern of skin absence, the presence of associated malformation and the mode of inheritance with unknown cause. We had a new born female infant with this disorder, who presented with a full thickness skin defect on scalp and skull defect. No skin defect were reported in other family members, including a first child born several years previously. Chromosomal analysis revealed as normal female karyotype, but she had double pelvis and double ureter of both kidney The legions healed for five weeks by conservative treatment as moist wound dressing and systemic antibiotic administrations. As a relatively uncommon skin anomaly with congenital anomaly, one case of aplasia cutis congenita involving scalp and skull is reported with the review of reference.

Archives of Reconstructive Microsurgery 2016;25(1):1-6
PURPOSE: The external ear is a common area of trauma on the body prone to exposure of ultraviolet light, which can lead to skin cancer. Thus, variable techniques have been developed and used for reconstruction of the external ear. The aim of this study is to review the surgical method, its area of application, as well as advantages and pitfalls of reconstruction of the external ear with inferior based retroauricular flaps. MATERIALS AND METHODS: Eight patients underwent external ear reconstruction with inferior based retroauricular flap for external ear defects in our institute from September 2012 to June 2015. According to the area of the defect, patients were classified as middle 1/3 (n=4), inferior 1/3 (n=2), superior auroculo-cephalic sulcus (n=1), and external auditory canal (n=1). RESULTS: All of the flaps survived the operation and there was no marginal necrosis. Mean size of the defect was 2.8×1.8 cm and mean size of the retroauricular flap was 5×2 cm. For insetting of the flap, a subcutaneous tunneling technique was used in 6 cases and rotation without subcutaneous tunneling was used in 2 cases. Transient paresthesia occurred in 3 cases. Two cases recovered within 3 months but one case did not recover until 6 months. CONCLUSION: The inferior based retroauricular flap is an available technique in external ear reconstruction with one stage operation.

3.Risk and Effectiveness of Using Thrombin in Microvascular Free Tissue Transfer.
Archives of Reconstructive Microsurgery 2014;23(1):1-7
PURPOSE: Recent studies have reported on application of fibrin glue composed of fibrinogen and thrombin to nerve anastomosis, which can be another candidate for vessel anastomosis. However, no research regarding the risk and effectiveness of thrombin in microvascular free tissue transfer has been reported. Therefore, the aim of study is to determine the risk and effectiveness of thrombin on microvascular free tissue transfer through clinical cases. MATERIALS AND METHODS: Twenty-five patients underwent free flap reconstruction for soft tissue defect or bone exposure in our institute from March 2011 to February 2014. In the group using thrombin, dissolved powder thrombin (5,000 IU/amp) was mixed with 10 mL normal saline. Saline mixed with thrombin was applied on the flap, recipient, and around vessel anastomosis. In the control group, free flap was performed using the same method, except using thrombin. We analyzed the results between the two groups. RESULTS: All flaps survived. The group using thrombin included 14 patients and the control group included 11 patients. Hematoma was found in two cases, respectively, in each group. The group using thrombin showed lower incidence of hematoma than the control group. No difference in survival rate of the flap was observed between the thrombin group and the control group. CONCLUSION: Results of this study showed that use of saline mixed with thrombin in free tissue transfer may be safe and effective for prevention of hematoma formation in the recipient site.

4.Prevention and treatment of microstomia
Archives of Craniofacial Surgery 2024;25(3):105-115
The mouth, located in the lower third of the face, is a uniquely visible structure. It serves as a vital organ both aesthetically and functionally, playing a key role in speech, expression, and fundamental oral functions. Consequently, any alterations or defects in its shape, due to various causes, can lead to aesthetic and functional deficiencies. These issues may also result in challenges with social interactions and a decrease in confidence. In cases of microstomia, various surgical approaches are proposed based on the location, extent, shape, and cause of the defect, leading to numerous case reports. Plastic surgeons are proficient in oral reconstruction; however, cases of microstomia are relatively rare, which reduces their familiarity and interest in these cases. Additionally, preferences for oral size and shape vary according to factors such as geographical region and ethnicity, further complicating the functional definition of microstomia. Therefore, both subjective patient and physician judgments play crucial roles in the diagnosis and treatment of microstomia, as these may vary depending on individual and societal aspects. This review aims to classify the various causes and definitions of microstomia, as well as its non-surgical and surgical treatment options, with the goal of the treatment of this condition.
5.Evaluation of the Forearm Dominancy Artery for Invasive Vascular Procedure with 3D-CT Angiography.
Journal of Korean Medical Science 2015;30(9):1302-1307
The aim of this study was to evaluate the vascular dominance in the forearm as a factor in determining the choice of invasive vascular procedures in arteries of the forearm, using 3D-computerized tomography (3D-CT) angiographies of 92 forearms. The diameters of the ulnar and radial arteries were measured just distal to the bifurcation of the brachial artery, at the midpoint between the bifurcation and the wrist, and at the wrist crease. In 79 cases, the ulnar artery was larger than the radial artery after the bifurcation of the brachial artery. However, no statistically significant difference was observed at either the mid-forearm or the wrist crease. In the remaining 13 cases, the diameter of the radial artery was larger or the same as that of the ulnar artery after the bifurcation, but at the more distal sites no regular pattern could be detected. The findings suggest that 3D-CT angiography offers valuable preoperative details of the forearm vessels for cases requiring invasive vascular procedures on the forearm.

6.Fractional Photothermolysis of a Replanted Nose: A Case Report.
Archives of Aesthetic Plastic Surgery 2015;21(1):23-25
Although several cases of successful reconstruction of complete nasal amputations have been reported, reconstruction of a traumatic amputated nose remains a challenge both aesthetically and functionally. Even if replantation of the nasal tip is successful, the scar on the nose may develop an irregular appearance, an ill-fitting contour, a trap door deformity, or discoloration. In the predominant nasal tip, these suboptimal results are very stressful for patient. There are no guidelines for both management and postoperative care of traumatic nasal amputation. At the completion of laser scar revision after successful replantation, we present an excellent aesthetic outcome using the 1,550-nm fractional erbium-glass laser (MOSAIC(R), Lutronic Co. Ltd, Seoul, Korea). Based on our experience, a microvascular replantation followed by fractional non-ablative laser therapy was not harmful and was available to maximize the aesthetic outcomes.

The main challenge in pharyngoesophageal reconstruction is the restoration of swallow and speech functions. The aim of this paper is to review the reconstructive options and associated complications for patients with head and neck cancer. A literature review was performed for pharynoesophagus reconstruction after ablative surgery of head and neck cancer for studies published between January 1980 to July 2015 and listed in the PubMed database. Search queries were made using a combination of 'esophagus' and 'free flap', 'microsurgical', or 'free tissue transfer'. The search query resulted in 123 studies, of which 33 studies were full text publications that met inclusion criteria. Further review into the reference of these 33 studies resulted in 15 additional studies to be included. The pharyngoesophagus reconstruction should be individualized for each patient and clinical context. Fasciocutaneous free flap and pedicled flap are effective for partial phayngoesophageal defect. Fasciocutaneous free flap and jejunal free flap are effective for circumferential defect. Pedicled flaps remain a safe option in the context of high surgical risk patients, presence of fistula. Among free flaps, anterolateral thigh free flap and jejunal free flap were associated with superior outcomes, when compared with radial forearm free flap. Speech function is reported to be better for the fasciocutaneous free flap than for the jejunal free flap.

Bilateral pectoralis major myocutaneous (PMMC) flaps are commonly used to reconstruct large chest wall defects. We report a case of large chest wall defect reconstruction using bilateral PMMC flaps augmented with axillary V-Y advancement rotation flaps for additional flap advancement. A 74-year-old male patient was operated on for recurrent glottic squamous cell carcinoma. Excision of the tumor resulted in a 10×10 cm defect in the anterior chest wall. Bilateral PMMC flaps were raised to cover the chest wall defect. For further flap advancement, V-Y rotation advancement flaps from both axillae were added to allow complete closure. All flaps survived completely, and postoperative shoulder abduction was not limited (100° on the right side and 92° on the left). Age-related skin redundancy in the axillae enabled the use of V-Y rotation advancement flaps without limitation of shoulder motion. Bilateral PMMC advancement flaps and the additional use of V-Y rotation advancement flaps from both axillae may be a useful reconstructive option for very large chest wall defects in older patients.

Background:
Conventional radial forearm free flaps (RFFFs) are known to be safe, but can result in donor site complications. Based on our experiences with suprafascial and subfascial RFFFs, we evaluated the safety of flap survival and surgical outcomes.
Methods:
This was a retrospective study of head and neck reconstructions using RFFFs from 2006 to 2021. Thirty-two patients underwent procedures using either subfascial (group A) or suprafascial (group B) dissection for flap elevation. Data were collected on patient characteristics, flap size, and donor and recipient complications, and the two groups were compared.
Results:
Thirteen of the 32 patients were in group A and 19 were in group B. Group A included 10 men and three women, with a mean age of 56.15 years, and group B included 16 men and three women, with a mean age of 59.11 years. The mean defect areas were 42.83 cm² and 33.32 cm², and the mean flap sizes were 50.96 cm² and 44.54 cm² in groups A and B, respectively. There were 13 donor site complications: eight (61.5%) in group A and five (26.3%) in group B. Flexor tendon exposure occurred in three patients in group A and in none in group B. All flaps survived completely. A recipient site complication occurred in two patients (15.4%) in group A and three patients (15.8%) in group B.
Conclusions
Complications and flap survival were similar between the two groups. However, tendon exposure at the donor site was less prevalent in the suprafascial group, and the treatment period was shorter. Based on our data, suprafascial RFFF is a reliable and safe procedure for reconstruction of the head and neck.

The radial forearm free flap (RFFF) has become popular for head and neck reconstructions. Owing to a constant anatomy the RFFF is relatively easy to dissect. Nevertheless, anatomical variations of the radial artery have been reported. Some variations could affect the survival of the flap. This paper reports an unusual anomaly of the radial artery where the radial artery was not located between the brachioradialis (BR) and flexor carpi radialis. The radial artery was observed above the BR and on the radial side of the BR. The survival of the elevated flap was deemed questionable because it had only few perforators. So we decided to discard the flap and to elevate another free flap for the head and neck defect. The donor area on the forearm was covered using the original skin of the first flap as a full-thickness skin graft. This case highlights a means to deal with anomalies of the radial artery encountered during the elevation of RFFF and the checking process for variations of the radial artery before RFFF.
