The auricle is a three-dimensional cartilaginous frame covered with thin overlying skin. Due to its complex features, reconstructing helical rim defects after the excision of an auricular mass is challenging. Shortage of subcutaneous tissue and the presence of a tightly bound epithelium further hamper the primary closure of lateral (anterior) auricular skin defects. We present herein a case in which we used a helical rim advancement flap along with an additional postauricular skin flap. We achieved a satisfactory esthetic result with minimal loss of helical diameter and a low risk of flap necrosis by preserving the vascular network of the flap. This technique is less traumatic and will facilitate faster healing as well as improved patient recovery.

Oral and Maxillofacial defects is produced by trauma or cancer surgery. This defects have been shown functional loss such as mastication, swallowing, speech and psychosocial esthetic problem. Oral and Maxillofacial defects is reconstructed by the use of many flaps. However although previous flap surgery was done, additional soft tissue defects can be still remained. In this case, Walk-Up flap that is introduced by Marx RE in 1990 is recommended for successful reconstruction. We report Walk-Up flap for reconstruction of remained soft tissue defects of tongue S.C.C. After induction chemotherapy, tongue S.C.C. is excised surgically and reconstructed by use of PMMC flap. Post-op infection results in surrounding soft tissue defect with oro-facial fistula. We have experienced a case of Walk-up flap by use of PMMC flap for reconstruction with satisfactory result, so we report it with literature reviews.

Purpose: Soft tissue defect on foot and ankle is vulnerable and requires a thin flap for improvement of aesthetic and functional results. Lateral supramalleolar flap is a simple and fast procedure, which can preserve and supply reliable constant blood flow, and causes fewer donor site complications. The authors reviewed our cases and report the clinical results. Materials and Methods: Ten cases of soft tissue defects on the lower leg, around the ankle were treated with lateral supramalleolar flap. There were seven males and three females with a mean age of 54.8 years. The mean size of flaps was $5.9{\times}6.3$ cm and the mean follow-up period was 23 months. Flap survival and postoperative complications were evaluated. Results: Nine flaps survived completely without loss of flap. There was one case of partial wound dehiscence requiring debridement and repair, and another case of necrotic flap change requiring partial bone resection and closure. All patients were capable of weight bearing ambulation at the last follow up. Conclusion: The authors suggest that the lateral supramalleolar flap could be a useful option for treatment of soft tissue defect around the ankle joint.

Severe upper and lower extremity trauma may result in soft tissue loss with exposed bone and the subsequence of risk of chronic osteomyelitis or malunion of fracture fragments. Such injuries present a major reconstructive problem. But Since the introduction of microsugical technique, free muscle and myocutaneous flaps were employed to provide coverage of severely injured defects. Since Tai and Hasegawa(1974) first reported a breast reconstruction using by rectus abdominis myocuraneous flap, the free rectus myocutaneous flap has been widely employed for breast reconstuction, head and neck reconstruction, and extremity reconstruction in these days. The authors present their successful experience with free rectus abdominis muscle and rectus abdominis myocutaneous flaps for upper and low extremity reconstruction. From Nov. 94, to May 95, Five cases of severely injured extremites due to trauma or contact burn were treated with free rectus abdominis muscle flap or free rectus abdominis myocutaneous flap. All flaps except 1 case were survived without severe complications. As free muscle or myocutaneous flap, the free rectus abdominis flap has the advantages of a reliable pedicle, easy dissection, and an acceptable donor site, so it seems logical to apply the free rectus abdominis flap to apply in upper and lower extremity reconstruction.

Background Adipofascial flaps covered with a skin graft address the challenges involved in reconstructing dorsal foot defects. The purpose of this study was to describe a large adipofascial flap based on the perforators of the dorsalis pedis artery for large foot defects. Methods Twelve patients aged 5-18 years with large soft tissue defects of the dorsal foot due to trauma were treated with an extended dorsalis pedis adipofascial flap from May 2016 to December 2018. The flap was elevated from the non-injured half of the dorsum of the foot. Its length was increased by fascial extension from the medial or lateral foot fascia to the plantar fascia to cover the defect. All perforators of the dorsalis pedis artery were preserved to increase flap viability. The dorsalis pedis artery and its branches were kept intact. Results The right foot was affected in 10 patients, and the left foot in two patients. All flaps survived, providing an adequate contour and durable coverage with a thin flap. Follow-up lasted up to 2 years, and patients were satisfied with the results. They were able to wear shoes. Donor-site morbidity was negligible. Two cases each of partial skin graft loss and superficial necrosis at the tip of the donor cutaneous flap occurred and were healed by a dressing. Conclusions The hinged multiperforator-based extended dorsalis pedis adipofascial flap described herein is a suitable method for reconstructing dorsal foot defects, as it provides optimal functional and aesthetic outcomes with minimal donor site morbidity.

A soft tissue defect of the lower leg or foot presents a challenging problem. Reconstructive surgeon should be armed at all points of wound site, tendon and bone exposure, injury of major vessel and so on in the lower limb. We reconstructed the defects of lower legs and feet of 25 patients between February, 1997 and December, 2003. Applying reversed adipofascial flap with skin graft on a soft tissue defect of the lower leg or foot is challenging. We did a comparative study of 25 reversed adipofascial flaps with 51 free flaps. All 25 cases of reverse adpofascial flap reconstruction were successful except for a partial loss of skin graft in 3 occasions. The reversed adipofascial flap had a merit of a short operation time and hositalization, a high success rate and minimum complications. Besides major vessels in the lower leg are better preserved and donor morbidity is minimal. However, the flap is unmerited in reconstructing a hug hallowed defect and in the leg with poor blood circulation and once previous surgery. The operators may consider the feasible substitution of reversed adipofascial flap for free flap before applying in the lower leg.

Repairing surgical defects of the nose is still challenging due to its tridimensional shape and its aesthetic concern. Difficulty in reconstructing nasal subunits lies in their contour, skin texture and limited availability of adjacent skin. For lower nasal dorsum and supra-tip regions, we design a new combined local flap as existing local flaps may give disappointing results. This combination flap was performed on two patients for reconstruction of the lower nasal dorsum area after basal cell carcinoma excision. Size of the excision ranged from 20 to 25 mm diameter and safe margins were obtained. The defects were reconstructed with a local flap that combined a rotation nasal flank flap and a V-Y advancement nasolabial flap. Excision and reconstruction were performed in a one-stage surgery under intravenous sedation and local anesthesia. There were no postoperative complications and no flap loss occurred. Aesthetic and functional results after 6 months postoperatively were satisfying without modification of nasal shape. This flap is reliable and offers interesting functional and aesthetic outcomes. It can be considered as a new reconstruction alternative for supra-tip and lower nasal dorsum skin defects performed in a one-stage procedure under local anesthesia.

Purpose: The digital artery perforator flap was recently introduced and has been proven to be useful for reconstruction of various finger defects. Short operative time, less invasive surgery, and reliable flap circulation are the major advantages of this flap. The authors presented the clinical cases of the digital artery perforator flap and compared them with the distant flaps within a hand (thenar and hypothenar flaps) to reveal their differences. Methods: From May of 2006 to February of 2009, the authors performed reconstructions of finger defects with the digital artery perforator flaps in 10 patients as with the distant flaps within hand in 9 patients (7 thenar and 2 hypothenar flaps). In these two groups of the patients, flap size, use of skin graft, length of stay in hospital, healing time, complications were reviewed retrospectively and compared with statistical analysis (Student's t-test). Results: All flaps survived completely. The mean size of the perforator flap was $0.9{\times}1.9\;cm$ and the mean distant flap within a hand was $1.9{\times}2.0\;cm$. The use of skin graft was reduced in the perforator group because the donor site of the flap was closed primarily. The hospitalization period and healing time also reduced significantly in the perforator group. Minor complications (partial flap loss) were noted in small percentages in both groups but resolved with conservative management. Mean follow-up period was about 6 weeks. Conclusion: The digital artery perforator flap was smaller than the distant flap but its reconstruction of finger defects was reliable and comparable to the conventional distant flaps within a hand. This flap would be not only an alternative method but very useful in the management of various finger defects, because of ease of operative technique, less invasive surgery, decreased need of skin graft, and shorter period of hospitalization and healing time.

Purpose: Reconstruction of soft tissue defects with osteomyelitis in the lower third of the leg represents a challenge to plastic surgeons. Moreover, it is more arduous in multimorbid patients. One excellent option for reconstruction of these defects is to use a delayed distally based sural flap. Methods: We successfully used delayed distally based sural flap with a two-step procedure. During the first operation, radical debridement and elevation of flap were performed. The raised flap was fixed again at the donor site. The delay period ranged from seven to ten days. Between August 2008 and July 2009, we underwent operations for five patients using this technique. The size of flap varied from $10{\times}6\;cm$ to $12{\times}14\;cm$. Results: All flaps successfully survived. Partial skin loss of the grafted site was seen in two patients but no further surgical procedure was required for wound healing. Complaints of hypoesthesia on the lateral part of the foot was observed. In a three month follow-up period, hypoesthesia was resolved spontaneously. Conclusion: Delayed procedure improves the viability of distally based sural flap in high risk, critically multimorbid patients. We recommend that, if a two-stage operative approach is required, the delayed procedure should be considered.
