"Depressor Flaps" for Large Defects of the Lower Lip and Mental Region
2004
Innervated muscle cutaneous flaps are the result of a long evolution in labial reconstruction techniques. The use of these flaps to reconstruct the lower lip is now common practice thanks to such techniques as the stair case advancement flap, the Karapandzic flap,and the gate flap. In contrast, techniques that make use of depressor muscles of the lower lip are underutilized. In 1995 we published our first results on the reconstruction of full-thickness lateral losses of substance in the lower lip using a depressor anguli oris muscle cutaneous flap.In 1998 we published an article on the use of a platysma muscle cutaneous flap to reconstruct losses of substance in the labial region that exten…
Platysma Muscle Cutaneous Flap for Large Defects of the Lower Lip and Mental Region
1998
Based on the experience acquired using the depressor anguli oris flap for lateral lower lip reconstruction, the authors in this paper present their own technique to reconstruct large deficits of the lower lateral lip, involving the commissure and the mental region, by means of a platysma muscle cutaneous flap with a triangular skin island. The flap is oriented in the mandibular cheek region. The skin and the platysma muscle fibers, which run vertically, are incised and turned 90 degrees, so the edges of the platysma fibers are sutured to the edge of the residual orbicularis. The mucosal layer and the vermilion are reconstructed with a rotational flap from the cheek mucosa. The motor nerve a…
Quantitative assessment and localization of the hollowing of the temple after craniectomy and cranioplasty–The frontozygomatic shadow
2021
Background After cranioplasty, in many cases a not negligible soft tissue defect remains in the temporozygomatical area, also referred to as a hollowing defect of the temple. Objective To assess the precise localization and volume of the hollowing defect, to optimize future cranioplasties. Methods CT data of patients who received craniectomy and conventional CAD cranioplasty in our institution between 2012 and 2018 were analyzed. CT datasets prior to craniectomy and after cranioplasty were subtracted to quantify the volume and localization of the defect. Results Out of 91 patients, 21 had suitable datasets. Five cases had good cosmetic results with no defect visible, 16 patients had an app…
Bipedicled DIEAP flaps for reconstruction of limb soft tissue defects in male patients.
2016
Summary Background Extensive soft tissue deficiencies involving the limbs can be difficult to reconstruct and may require more than one microsurgical flap transfer to cover the defect. This can be particularly challenging in male patients, where the sacrifice of a donor muscle could result in considerable comorbidity. This paper describes the use of the bipedicled deep inferior epigastric artery perforator (DIEAP) flap to perform a one-stage reconstruction of extensive soft tissue defects in male patients. Methods By using preoperative multidetector computed tomographic (MDCT) angiography, the dominant perforators of the abdominal wall were identified and the bipedicled DIEAP flap was used …
Microsurgical treatment of midfacial tumours involving the skull base
1998
Various approaches to the base of the skull for the treatment of cranial base tumours are described in detail. Advantages and disadvantages of the particular approaches are discussed. This clinical experience is based on 303 neoplasms involving the base of the skull, operated on by the authors. Retrospective survival studies are presented and a review of the literature on the subject is discussed. Utilizing microsurgical techniques the 2-, 3- and 5-year survival rates were significantly improved. The functional and aesthetic outcomes were also dramatically superior compared with standard ablative procedures. Reconstructive postoperative strategies are suggested.
Therapy and prognosis of extraoral malignant melanoma metastasizing to the jaw: case report and literature review.
2009
t a d With approximately 75% of all skin cancer-related deaths, malignant melanoma (MM) is the most lethal among common skin cancers, mostly because of its disposition to early lymphogenic and hematogenic metastasis. If a MM is diagnosed early, the overall prognosis is excellent, but once metastasized it becomes an incurable disease with high mortality. Prognosis is dependent on parameters such as gender, anatomic location, level of invasion, thickness, type of primary tumor, ulceration, and number and status of regional lymphatic nodes. For incidence and mortalty, a decrease in young but an increase in older roups—with geographic differences—has been reported. Because of the embryologic or…
The dorsal lamina of the rectus sheath: a suitable grafting material for the penile tunica albuginea in Peyronie's disease?
2005
OBJECTIVE To estimate the morphological suitability of human connective tissue structures from different regions as graft material in Peyronie's disease, and to present preliminary results from 12 patients with grafting of corporal bodies using autologous rectus sheath. PATIENTS AND METHODS In five male cadavers the penile tunica albuginea was compared with the dorsal lamina of the rectus sheath, the palmar aponeurosis, the iliotibial tract and the Achilles tendon by using histological sections stained with haematoxylin and eosin, Crossmon's trichrome stain and resorcin-fuchsin. Surgical results and complication rates were investigated in 12 patients with Peyronie's disease after grafting t…
Blood metal levels after minimally invasive repair of pectus excavatum
2021
Abstract OBJECTIVES Minimally invasive repair of pectus excavatum (MIRPE) is the most popular surgical approach for paediatric patients with pectus excavatum. A substernal stainless still bar is inserted and left in place for 3 years and then removed. Our goal was to investigate blood metal levels after MIRPE and to correlate them with surgical details, such as the numbers of bars and stabilizers and the length of time the bar was in place. METHODS Blood levels of iron, chromium, manganese, molybdenum and nickel were analysed in 130 teenagers (108 boys and 22 girls) who had MIRPE using inductively coupled plasma mass spectrometry. A total of 62 patients were operated on using MIRPE (study…
Reconstruction with a pectoralis major myocutaneous flap after left first rib and clavicular chest wall resection for a metastasis from laryngeal can…
2016
We presented a case of recurrent metastasis from epidermoid cancer that occurred in the left clavicle of a patient with a history of laryngeal cancer treated on April 2005 with extended hemilaryngectomy, neck dissection and chemoradiation therapy. On September 2008, he developed a left clavicular metastasis. The disease was initially well controlled by chemoradiotherapy but it recurred 17 months later. The optimal treatment plan was established by several multidisciplinary meetings and the patient subsequently underwent an en bloc resection of the left clavicle, first rib and all the other involved structures. Coverage of the thoracic defect was achieved using pectoralis major myocutaneous …
Characteristics, Management Techniques, and Outcomes of the Most Common Soft-Tissue Hand Tumors: A Literature Review and Our Experience
2017
INTRODUCTION Diagnosis of the hand's soft-tissue tumors is often difficult because of the different anatomic structures present in this region and yet clinicians must be able to distinguish typical benign entities from life-threatening or limb-threatening malignant diseases. MATERIALS AND METHODS At the Department of Plastic and Reconstructive Surgery at the University of Palermo, 629 patients with hand tumors were studied. Treatment was surgical for all of them; also radiotherapy and chemotherapy were necessary based on the histological diagnosis. CONCLUSIONS Our retrospective study with a literature review aims to present the most commonly observed soft-tissue hand lesions, analyzing thei…
