The challenges of successful nasal reconstruction, which are related to the anatomical complexity of the region, have been extensively studied. Revisional operations are often required to achieve proper nasal reconstruction, with results resembling the premorbid nasal status. This is necessary to ensure the quality of life of skin cancer patients. Fundamental nasal reconstruction requires both proper soft tissue coverage and proper function. However, earlier studies in the field primarily focused on the functional aspect of nose reconstruction, although the cosmetic aspect is also an important factor to consider. In response to this need, many recent studies on nose reconstruction have proposed various refinement strategies to improve aesthetic satisfaction. Most plastic surgeons accept the nasal aesthetic subunit principle as a standard for nasal reconstruction. This review outlines the commonly used surgical refinement options and management strategies for postoperative complications based on the subunit principle. In patients with nasal defects, a proper technical strategy might help minimize revision operations and optimize the long-term results.

Free or pedicled vascularized fibular grafts (VFG) are useful for the reconstruction of large skeletal defects, particularly in cases of scarred or avascular beds, or in patients with combined bone and soft tissue defects. Compared to non-VFG, VEG, which contains living osteocytes and osteoblasts, maintains its own viability and serves as good osteoconductive and osteoinductive graft. Due to its many structural and biological advantages, the free fibular osteo- or osteocutaneous graft is considered the most suitable autograft for the reconstruction of long bone defects in the injured extremity. The traditional indication of VFG is the long bone and soft tissue defect, which cannot be reconstructed using a conventional operative method. Recently, the indications have been widely expanded not only for defects of midtibia, humerus, forearm, distal femur, and proximal tibia, but also for the arthrodesis of shoulder and knee joints. Because of its potential to allow further bone growth, free fibular epiphyseal transfer can be used for the hip or for distal radius defects caused by the radical resection of a tumor. The basic anatomy and surgical techniques for harvesting the VFG are well known; however, the condition of the recipient site is different in each case. Therefore, careful preoperative surgical planning should be customized in every patient. In this review, recently expanded surgical indications of VFG and surgical tips based on the author's experiences in the issues of fixation method, one or two staged reconstruction, size mismatching, overcoming the stress fracture, and arthrodesis of shoulder and knee joint using VFG are discussed with the review of literature.

Backgrounds: The purpose of this study is to discuss the total joint reconstruction surgery for a patient with recurrent ankylosis in bilateral temporomandibular joints (TMJs) using three-dimensional (3D) virtual surgical planning, computer-aided manufacturing (CAD/CAM)-fabricated surgical guides, and stock TMJ prostheses. Case presentation: A 66-year-old female patient, who had a history of multiple TMJ surgeries, complained of severe difficulty in eating and trismus. The 3D virtual surgery was performed with a virtual surgery software (FACEGIDE, MegaGen implant, Daegu, South Korea). After confirmation of the location of the upper margin for resection of the root of the zygoma and the lower margin for resection of the ankylosed condyle, and the position of the fossa and condyle components of stock TMJ prosthesis (Biomet, Jacksonville, FL, USA), the surgical guides were fabricated with CAD/CAM technology. Under general anesthesia, osteotomy and placement of the stock TMJ prosthesis (Biomet) were carried out according to the surgical planning. At 2 months after the operation, the patient was able to open her mouth up to 30 mm without complication. Conclusion: For a patient who has recurrent ankylosis in bilateral TMJs, total joint reconstruction surgery using 3D virtual surgical planning, CAD/CAM-fabricated surgical guides, and stock TMJ prostheses may be an effective surgical treatment option.

Background: Defects of the nasal ala and tip have a complex three-dimensional structure that makes them challenging to reconstruct. Many reconstructive options have been described for nasal ala and tip defects, ranging from primary closure to local flaps and skin grafts. However, it is difficult to determine which method will yield the best cosmetic results in each individual case. Thus, the purpose of this study was to determine which surgical procedures for reconstructing defects of the nasal ala and tip have better cosmetic results. Methods: From 2008 to 2018, 111 patients underwent surgery to reconstruct skin defects after resection of skin cancer in the nasal ala or tip. Their charts were reviewed to obtain data on age, sex, surgical location, size of the defect, surgical method, and cosmetic results using a visual analog scale (VAS). Results: For nasal ala reconstruction, the most commonly used surgical technique was the nasolabial flap (n= 42). This method also had the highest VAS score (7/10). The most commonly selected surgical method for nasal tip reconstruction was the bilobed flap (n= 13), and bilobed flaps and primary closure had the highest VAS score (7/10). Conclusion: Nasolabial flaps showed excellent cosmetic results for the reconstruction of nasal ala defects, while primary closure and bilobed flaps yielded excellent cosmetic results for the reconstruction of nasal tip defects.

Background: The medial canthal region features a complex three-dimensional and internal anatomical structure. When reconstructing a defect in this area, it is crucial to consider both functional and aesthetic aspects, which presents significant challenges. Generally, local flaps are preferred for reconstruction; however, skin grafts can be used when local flaps are not feasible. Therefore, we conducted a comparative analysis of surgical outcomes skin grafts when local flaps were not feasible, to determine which surgical method is more effective for medial canthal region reconstruction. Methods: Twenty-five patients who underwent medial canthal region reconstruction using skin grafts or local flaps from 2002 to 2021 were enrolled. Patient information was obtained from medical records. Five plastic surgeons evaluated the surgical outcomes based on general appearance, color, contour, and symmetry. Results: Skin grafts were used in eight patients and local flaps were used in 13. Combined reconstructions were employed in four cases. Minor complications arose in four cases but improved with conservative treatment. No major complications were reported. Recurrence of the skin cancer was noted in two cases. All categories showed higher scores for the local flap compared to both skin graft and combined reconstruction; however, the differences were not statistically significant respectively. Conclusion: The choice of appropriate surgical methods for reconstructing defects in the medial canthal region depends on various factors, including the patient's overall health, the size and depth of the defect, and the degree of involvement of surrounding structures. When a local flap is not feasible, a skin graft may provide favorable surgical outcomes. Therefore, a skin graft can serve as a viable alternative for reconstructing the medial canthal region.

Although various methods had been reported for reanimination of facial nerve palsy, interposition nerve graft remains superior to other methods if there is a wide gap to be bridged. Dott described a excllent facial nerve reconstruction by sural nerve graft bypassing petrous bone. But his method needs two surgical fields and is performed in two stages. Authors desribe a traumatic facial nerve palsy treated by one stage facial nerve reconstruction that is performed in one surgical field by using a great auricular nerve interposition graft and bypass the petous bone.

Background Nipple-areolar complex (NAC) reconstruction following curative mastectomy is traditionally performed as a second-stage procedure several months after initial breast reconstruction. The recent literature has documented the increasing popularity of immediate nipple reconstruction carried out simultaneously during autologous reconstruction. The aim of this study was to evaluate the surgical outcomes and patient satisfaction with immediate breast and nipple reconstruction performed in a single stage after skin-sparing mastectomy. Methods All patients who underwent a skin-sparing mastectomy with immediate latissimus dorsi flap breast and NAC reconstruction as a single-stage procedure from 2007 to 2015 were included. Patient demographics, oncologic details, and surgical outcomes were recorded. The BREAST-Q questionnaire was administered to patients to assess the impact and effectiveness of this reconstructive strategy. Results During the study period, 34 breast and NAC reconstructions in 29 patients were performed at Cork University Hospital. The majority of our patient cohort were non-smokers (93.1%) and did not receive adjuvant radiotherapy. Postoperative complications were infrequent, with no cases of partial necrosis or complete loss of the nipple. The response rate to the BREAST-Q was 62% (n=18). Patients reported high levels of satisfaction with the reconstructed breast ($62{\pm}4$), nipple reconstruction ($61{\pm}4.8$), overall outcome ($74.3{\pm}5$), and psychosocial well-being ($77.7{\pm}3.2$). Conclusions Skin-sparing mastectomy with immediate nipple reconstruction during autologous latissimus dorsi reconstruction was demonstrated to be a safe and aesthetically reliable procedure in our cohort, yielding high levels of psychological and physical well-being. A single-stage procedure promotes psychosocial well-being involving issues that are intrinsically linked with breast cancer surgery.

Preoperative patient analysis for oral cancer involves multiple considerations that are based on multiple factors; these include TNM stages, histopathologic findings, and adjacent anatomical structures. Once the decision is made to excise the lesion, the margin of dissection and its extent should be considered along with the best form of reconstruction and airway management. Treatment methods include surgical resection, radiotherapy, and chemotherapy. Although the combined method of treatment is controversial, surgical resection is considered predominantly, and immediate reconstruction after surgical resection follows. The choice of treatment is dictated by the anticipated functional and esthetic results of treatment and also by the availability of a surgeon with the required expertise. Segmental mandibulectomy with primary reconstruction has been shown to have advantages in both functional and esthetic results. A 52-year-old male patient with basaloid squamous cell carcinoma of the floor of the mouth, and the anterior portion of the mandible was treated with surgical procedures that included segmental mandibulectomy with both supraomohyoid neck dissection (SOHND) at Levels I-III and mandible reconstruction with a left fibula free flap. A 55-year-old male patient with clear cell odontogenic carcinoma of the oral cavity underwent segmental mandibulectomy with both SOHND at Levels I-III and mandible reconstruction with a left fibula free flap. The purpose of this study was to review the anatomic and functional results of patients after immediate reconstruction with a fibula free flap following resection of carcinoma in the anterior portion of the mandible and floor of the mouth.

Implant-based breast reconstruction is the most commonly used reconstruction technique after mastectomy. This is because skin-sparing mastectomy has become possible with advancements in oncology. In addition, the development of breast implants and the advent of acellular dermal matrices have reduced postoperative complications and resulted in superior cosmetic results. The most frequently performed surgical breast reconstruction procedure for the past 20 years was the insertion of an implant under the pectoralis major muscle by means of the dual plane approach. However, some patients suffered from pain and animation deformity caused by muscle manipulation. Recently, a prepectoral approach has been used to solve the above problems in select patients, and the results are similar to subpectoral results. However, this technique is not always chosen due to the number of considerations for successful surgery. In this article, we will discuss the emergence of prepectoral breast reconstruction, indications and contraindications, surgical procedures, and outcomes.
