A 7-Step Guide to High-Definition Liposuction.

BACKGROUND: High-Definition (HD) Liposuction refers to the most advanced body contouring technique, offering an athletic and healthy body appearance. The latest available devices, the criteria of proper selection, and an expert surgeon's tips are highlighted in a 7-step guide approach. METHODS: A retrospective study of prospectively maintained database was conducted from 2015 to 2020. Demographic information, personal history, outcomes, complications were collected and analyzed from 568 patients who underwent the same surgical procedure. RESULTS: 568 patients (247 male and 321 female) were included in the study with a mean BMI of 25.6 (range 21-29 kg/m2) and follow up time ranging from 1 to 48 months. The first 50 procedures represented the initial learning curve, during which most complications had occurred (14 patients/50 patients). Using the 7-step guide, we managed to minimize the overall complications to a rate of 3%. CONCLUSION: The outlined steps have been simplified in a 7-step guide for plastic surgeons to understand, practice and refine HD liposuction in a contemporaneous, efficient, and reproducible manner.

The management of locally advanced head and neck squamous and basal cell carcinomas.

PURPOSE: The management of locally advanced head and neck basal (BCC) and squamous cell (SCC) carcinomas has been controversial and often debated. The purpose of the current study was to present our experience in the treatment of non-melanotic head and neck skin malignancies. METHODS: From 2000 to 2017, 34 patients with locally advanced head and neck skin tumors were treated in our hospital with wide local excision and immediate reconstruction mainly with rotational flaps, free tissue transfers and skin grafting. RESULTS: Histopathological examination revealed 10 BCCs, 22 SCCs and 2 cases of metatypical basal cell carcinomas. All patients were successfully submitted to ablative procedure with minimal morbidity and acceptable cosmetic results. CONCLUSIONS: Locally advanced head and neck SCCs and BCCs are large tumors that may invade adjacent structures or infiltrate into deep tissues. Complex reconstructive methods are needed to close the defect, with free tissue transferring being a reliable option. Finding clear margins is crucial in order to prevent unnecessary morbidity and local recurrence.

Perineal Reconstruction with a Diamond-shaped Perforator Flap: A Case Report.

Reconstruction of perineal defects is a challenging procedure. Various surgical techniques have been proposed. Compared with traditional myocutaneous flaps, pedicled perforator flaps are believed to be a less invasive option for perineal reconstruction, with better functional and cosmetic results. We present the case of a 47-year-old woman with a perianal Paget's disease who underwent surgical excision of the lesion. The reconstructive technique was a pedicled flap based on an internal pudendal skin perforator artery. The flap was designed in a diamond-shaped pattern. Six months after the operation, the patient is disease-free with successful aesthetic and functional results. A polygonal diamond-shaped flap is an easy and reliable choice for perineal reconstruction, offering better adjustment in the perianal region and avoidance of the curvilinear perianal incision (which often leads to anal stenosis).

The Anterolateral Thigh Perforator Flap in an Innovative Microsurgery Training Method.

The road to becoming a good and confident microsurgeon requires love for your work, patience, and good training facilities. Safe and effective training procedures for young microsurgeons during their plastic surgery residency are necessary and should be applied under standardized conditions. We present an innovative microsurgical training method for plastic surgery residents in the operation theater concerning the anterolateral thigh perforator flap (ALT). In a 2-team approach, the ALT flap harvesting begins parallel to tumor resection. Although the tumor excision team still works in the tumor region, and after the reconstructive team has successfully completed the ALT dissection, residents can work distally to the origin of the perforator vessel (which supplies the flap). Their training involves dissection and anastomosis of the continuation of the descending branch, distally to the perforator supplying the flap. Since 2015, eight operations have been performed with this innovative method with the participation of upcoming microsurgeons. A written informed consent is given to all patients. Our study resulted in the improvement of microsurgical skills of the young microsurgeons. There is no impact to the ALT perforator flap or to the operative time. This training procedure can be safely applied as a training method during plastic surgery residency under standardized conditions. We have the joy of seeing our resident's progress through their high success rates in microsurgery. We recommend this innovative procedure as an adequate teaching method during residency to promote the future of our specialty, and we hope that our students will become even better than their teachers.

Intramuscular granular cell tumor of the gluteal region.

Granular cell tumors are uncommon, usually benign neoplasms, mainly observed in the head and neck region, chest wall and upper extremities. These tumors account for ~0.5% of all soft-tissue tumors. Less than 2% are malignant. These are associated with poor prognosis. Clinical signs suspicious for malignancy are large size, rapid growth, invasion, recurrence and metastasis. Malignancy is confirmed by histological examination. We present the case of a 79-year-old patient with a 6-month history of a rapidly growing mass in the left gluteal region giving the clinical impression of a malignant tumor. The patient underwent surgical excision of the tumor and the pathology report revealed a granular cell tumor. In difficult cases, multidisciplinary approach is necessary for appropriate diagnosis and management.

Dermatofibrosarcoma protuberans coexisting in a patient with a vascular malformation-a rare coincidence.

Dermatofibrosarcoma protuberans with fibrosarcomatous differentiation (DFSP-FS) is a rare soft tissue tumor with more aggressive behavior and it is not clear what causes this type of skin cancer. We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory. She was initially treated by embolization as the sarcoma was misdiagnosed but the tumor within 6 months seemed to be growing rapidly and reached a giant dimension with ulceration and required surgical intervention. The patient underwent a surgical removal of the mass but as the pathology report included a DFSP-FS with close margins,a second operation was required. A wide local excision was performed and reconstruction of defect by using bilateral pectoralis major muscle flaps and a full thickness skin graft from the abdominal wall. Post operatively the patient was treated with radiotherapy.
