After the first face transplantation from woman to woman we performed in our clinic, it was aimed to eliminate the lack of knowledge about the subject in the literature by transferring our experiences and long-term results to the problems we had with the patient. A 20-year-old patient underwent partial osteomyocutaneous facial transplant (22nd facial transplant), which included 2 functional units of the face. The patient had no major problems in the early period and had a good aesthetic appearance.

Although the cancellation of elective procedures due to the COVID-19 outbreak has been a vital precaution, it has resulted in the suspension of aesthetic procedures and surgeries worldwide. Consequently, this postponement and other factors might have a negative impact on patients planning to undergo aesthetic procedures. Understanding the changes in patient motivation and perception in comparison to the prepandemic period is imperative for proper adjustment of plastic surgery clinics.

It has been established that many chemotherapeutic agents are associated with a variety of ocular side effects. As an antineoplastic agent, 5-fluorouracil (5-FU) is the chemotherapeutic agent that is frequently linked with cicatricial ectropion. Capecitabine is a prodrug of 5-FU and has a more favorable side effect profile than 5-FU.

Background: Although columellar strut grafts (CSGs) are considered among the fundamental steps for providing nasal tip support, a downward rotation of the nasal tip in patients with strut grafts can still be encountered. Patient-related factors such as nasal skin thickness can allow the plastic surgeon to anticipate certain drawbacks that can be encountered in the healing phase, but patient-based differences of nasal cartilage and the resulting impact have yet to be investigated. The purpose of this study was to evaluate the effect of the biomechanical properties of CSGs on late postoperative nasal tip position and support.

Background/aim: Even though new techniques are emerging to overcome the inconsistent long-term viability of fat grafts, current methods for increasing fat graft survival are not routinely adaptable to all clinical environments. The purpose of this study was to determine the efficacy of microneedling as an adjunct to fat grafting to the face. Materials and methods: Twenty-two patients that underwent fat grafting to the face with adjunctive microneedling were evaluated in terms of improvement in facial skin quality and facial volume and their results were compared to those in 18 patients that underwent fat grafting without microneedling.

Background: Xeroderma pigmentosum (XP) is an autosomal recessive disorder characterized by xerosis, ultraviolet light sensitivity, and cutaneous dyspigmentation. Due to defects in their DNA repair mechanism, genetic mutations and carcinogenesis inevitably occurs in almost all patients. In these patients, reconstruction of cutaneous malignancies in the head and neck area is associated with some challenges such as likelihood of recurrence and an aggressive clinical course.

Although fat grafts are considered the ideal soft-tissue fillers, the main concern dealing with this technique is not being able to predict long-term graft survival due to high absorption rates. The purpose of this study was to investigate the angiogenic effects of preconditioning the recipient area with micro-needling and to determine its overall impact on fat graft survival. The study consisted of a sham, control and study group.

Background: Cartilage grafts are used routinely in rhinoplasty, but are they necessary? Can we support the normal anatomy by preserving and transposing the adjacent tissues? In this study we hypothesize that during rhinoplasty, cartilage flaps can give adequate support and may decrease the need for cartilage grafts.

Methods: Included in this study were 147 patients who underwent an open rhinoplasty technique under general anesthesia between January 2010 and May 2012. Mean operative time was 73 min (range=44-120 min).

Introduction: Reconstruction of cranial bone defects is one of the most challenging problems in reconstructive surgery. The timing of reconstruction, the location of the defect, the materials to be used, and the medical history of the patient are parameters that have been mostly discussed in the literature. To the best of our knowledge, there has not been any published classification for the cranial bone defect reconstruction according to defect size.
