Transposition flap

BACKGROUND: The traditional nasolabial V-Y advancement flap is widely used for midface reconstruction, particularly for the lower third of the nose and upper lip, as its color and texture are similar to these areas. However, it provides insufficient tissue to cover large defects and cannot restore the nasal convexity, nasal ala, and adjacent tissues. The purpose of this study is to investigate the modified nasolabial V-Y advancement flap with extension limbs the along alar crease for the reconstruction of complex midface defects...

The objective of this study is to clarify whether the omental coating can effectively attenuate foreign body reaction (FBR) induced by implanted materials. Male Sprague-Dawley rats were injected with polydextran particle slurry intraperitoneally to activate the omentum. 7 days later, polyether polyurethane sponge discs were implanted subcutaneously on each side of the rat's back as the foreign implants to induce FBR. The next day, omental transposition were performed. The disc on the left side of each rat's back was wrapped with omental flap (omental group); the disc on the right side was untreated (control group)...

BACKGROUND: Large lateral cheek defects can be challenging to reconstruct. Several approaches to reconstruction of these defects have been reported. In the case presented here, we describe an alternative reconstruction method for this type of surgical defect. Detailed Case Description: We present one patient with a large basal cell carcinoma on his lateral left cheek who underwent a complete tumor removal by Mohs surgery and was left with a defect 6 × 6 cm in size. This large defect was closed by performing a double transposition flap under local anesthesia...

Tessier facial cleft is among the rarest facial clefts detailed in literary works and there are numerous issues contending around its multidisciplinary repairing methods. The authors describe a case of a 14-year-old girl with a neglected facial cleft associated with ADAM complex syndrome. The patient underwent soft tissue reconstruction using a combination of the forehead flap, bilateral mustardee flap, and Abbe flap. The results concerning the functional improvement for the soft tissue reconstruction are categorized as good in our terms...

BACKGROUND: Flap reconstruction after resection of a superficial malignant soft tissue tumor extends the surgical field and is an indicator for potential recurrence sites. AIM: To describe a grading system for surgical field extension of soft tissue sarcomas. METHODS: Grading system: CD-grading is a description system consisting of C and D values in the surgical field extension, which are related to the compartmental position of the flap beyond the nearby large joint and deeper extension for the pedicle, respectively...

Prolonged perineal wound healing following proctocolectomy in patients with inflammatory bowel disease (IBD) is a frustrating result for the medical team and patients who were hoping for improved quality of life. Prolonged healing, which lasts more than 6 months following proctocolectomy, is termed persistent perineal sinus (PPS) and typically necessitates further surgical management. Healing of the PPS is difficult due to the resulting "dead space" following proctocolectomy, necessitating the need to fill the void with viable tissue in an area with anatomic constraints...

Two steps are able to lead to a significant decrease in the incidence of skin cancer overall and/or to its parallel and successful surgical treatment. The first step concerns its non-occurrence or less frequent clinical manifestation and is largely related to the modern concept known as prevention, but not the one mainly related to solar radiation, but: 1) informing patients about the possible contamination of certain drugs with carcinogens/nitrosamines/NDSRIs and 2) making clinicians aware of the modern concept of limited to completely eliminated intake of nitrosamines/NDSRIs in medications...

BACKGROUND: The anterior ethmoidal artery (AEA) flap has been successful in repairing anterior nasal septal perforations and has been presumed to be axially based on AEA branches coursing through or around the cribriform plate (CP). However, limited evidence supports the flap's axial supply. The purposes of this cadaveric and computed tomography (CT) study were to assess the arterial anatomy from the CP to the septum, and to determine AEA flap length to predict ideal flap base width. METHODS: Ten fresh latex-injected cadavers were utilized for endoscopic dissection to identify arteries traversing the CPs on each side...

OBJECTIVE: This study aims to demonstrate a new surgical technique that can be applied in patients with cephalic malposition and patients with alar retraction. METHODS: In this technique, a cartilage incision is made between the upper 2/3 and lower 1/3 close to the caudal edge and parallel to the cephalic edge of the lateral crus. Following this incision, the cephalic lateral crus and middle crus are meticulously dissected away from the underlying vestibular skin...

Despite the aid of tissue expansion, the ideal design of random pattern flap is not always available in patients with extensive skin lesions. We investigated the effectiveness of surgical delay on expanded flaps in pediatric patients. Retrospective cohort study was performed on patients who underwent tissue expansion surgery for extensive skin lesions at Seoul National University Children's Hospital. The surgical delay technique was employed for patients with unfavorable flap conditions related to location or transposition angles...

Cryptotia is a congenital ear deformity characterized by the upper helix buried under the skin of the temporal region. Recurrence and inadequate correction of ear position are major complications following auricle reconstruction. Abnormalities of the auricular muscles are closely associated with cryptotia and considered to be the main cause. However, current corrective procedures focus on provision of additional skin and abnormal auricular muscle correction is considered supplementary. We report a surgical approach focused on the anatomical repositioning of the external auricular muscle insertions and skin cover with a mini flap...

Anal squamous cell carcinoma (ASCC) is the most common histological subtype of malignant tumor affecting the anal canal. Chemoradiotherapy (CRT) is the first-line treatment in nearly all cases, ensuring complete clinical response in up to 80% of patients. Abdominoperineal resection (APR) is typically reserved as salvage therapy in those patients with persistent or recurrent tumor after CRT. In locally advanced tumors, an extralevator abdominoperineal excision (ELAPE), which entails excision of the anal canal and levator muscles, might be indicated to obtain negative resection margins...

A 9 yr old female spayed domestic shorthair was presented with a 12-day history of stranguria. Six years previously, the cat had a bilateral perineal herniorrhaphy with cystopexy and pubic osteotomy. At presentation, survey radiographs and a positive-contrast vaginourethrocystogram were performed, which revealed cystolithiasis and recurrent bilateral perineal hernias with bladder retroflexion. A cystopexy was repeated, followed by bilateral perineal repairs using the internal obturator muscle flap transposition...

Primary cutaneous apocrine carcinoma (PCAC), a subtype of sweat gland carcinoma, is an extremely rare malignant neoplasm. Distinguishing an apocrine carcinoma from a breast carcinoma metastasis is difficult even for a pathologist. Most arise in regions of high apocrine gland density like the axilla, and rarely on the scalp and eyelid, but they can occur elsewhere on the skin. Primary cutaneous apocrine carcinoma of the scalp is a rare malignancy most often reported in the literature as case reports or small case series...

Giant keratinocyte tumors, in particular basal cell carcinomas of the scalp area, are a serious challenge for dermatosurgeons, oncologists, and maxillofacial and reconstructive surgeons. The scalp area is limited in terms of skin mobility, and its elasticity decreases with age. The size of the tumors in this area and the degree of infiltration of the underlying tissues are important for the therapeutic choice, from surgical removal, waiting for granulations to form, and placing a split skin mesh graft (at a later stage) to performing complex rotational/transpositional or advancement flaps...

Osteosarcoma is the most common primary malignant tumor affecting the bone but is a rare occurrence in the head and neck region. Complete surgical resection with wide surgical margins is currently the main treatment strategy for osteosarcoma but can be hard to achieve due to the complex anatomy of the head and neck. We report the first case of primary high-grade dedifferentiated parosteal osteosarcoma arising from the temporal bone in published literature. The 19-year-old patient presented with a left retroauricular lesion measuring 3 cm in diameter...

Moyamoya syndrome (MMS) is a progressive disease that can result in debilitating strokes. Surgical revascularization is the mainstay of treatment. Selection of the proper bypass technique depends on the vascular anatomy and location of the hypoperfused cerebral territory. We describe here a case of successful indirect bypass utilizing a pericranial flap as well as dural inversion. A seven-month-old female was transferred from an outside facility to our institution for further evaluation and surgical treatment of MMS...

Background Hypospadias is a common congenital anomaly that needs repair at an early age (six months to one year). Ironically, many cases in India present late due to a lack of healthcare facilities, poverty, and illiteracy. Adult patients are different from children as they are aware of their genitalia. They are concerned with the aesthetics and, predominantly, the potency. In this study, we present the perspectives and outcomes of 111 adult cases of hypospadias. Methodology In this retrospective study conducted between January 2010 and December 2020, 111 patients aged more than 14 years who were diagnosed with hypospadias of any level with or without mild-to-moderate chordee were included...

A 6-year-old boy with left main trunk (LMT) stenosis, who had undergone arterial switch operation (ASO) for transposition of the great arteries( TGA) before 6 years, underwent LMT orifice reconstruction. Coronary angiography showed severe stenosis of LMT, already when he was hospitalized with heart failure after 3 months of ASO. He was stable with oral treatment, therefore we performed the LMT reconstruction, before starting school, in terms of the risk of coronary ischemic event. We reconstructed the LMT ostium using an aortic flap and autologous pulmonary arterial patch...

Reconstruction of surgical defects after wide local excision of acral melanoma on the sole should allow patients to walk and bear weight. Moreover, certain options such as local transposition flaps can compromise follow-up. We present a case series of surgical defects on weight-bearing areas of the sole reconstructed using a synthetic dermal matrix and a split-thickness skin graft. This approach prevents surrounding tissue displacement and results in good functional outcomes assessed by baropodometry and computer-based podoscopy...
