Jaw in a day: Osseointegration of the implants in the patient’s leg before reconstructive surgery of a maxilla with ameloblastoma. A 4-year follow-up…

2021

Background To describe a clinical case of a cancer patient who underwent ablative tumor surgery, including treatment planning, surgical resection and subsequent implant rehabilitation. Case report A 61-year-old patient with a diagnosis of multicystic follicular ameloblastoma in the maxilla, in which it was necessary a multidisciplinary approach and two surgical steps. In the first surgical intervention osseointegrated implants (OII) were placed in the fibula, until their osseointegration period of 8 weeks was complete. Afterwards, in the second surgery, the micro-vascularized free fibular flap bearing the implants was transplanted into the oral cavity, in order to perform simultaneous recon…

Complications and Solutions in Propeller Flap Surgery

2020

AbstractPropeller perforator flaps (PPFs) have long been proven as valid reconstructive tools for a wide range of soft tissue defects in different body regions. During the last decade, despite their numerous advantages, many authors have thoroughly analyzed outcomes of these flaps, sometimes discouraging their use mainly because of a high failure rate. Accurate patient selection, adequate preoperative planning, and an appropriate dissection technique seem to potentially improve outcomes. Our study provides a review of the relevant literature related to PPF complications and of our experience, describing reasons for failure, measures for preventing them, and approaches for a prompt evaluatio…

Iatrogenic salivary duct injury in head and neck cancer patients: Report of four cases and review of the literature.

2013

Introduction: The lesions of the salivary ducts may be idiopathic, post- traumatic, or iatrogenic and lead to sialocele formation with persistent painful facial swelling or cutaneous fistula formation. No consensus on treatment of this condition exists: the options of treatment include needle aspiration, pressure dressings, antisialogogue therapy, radiotherapy, botulinum toxin and surgical approaches as duct repair, diversion, ligation, different drainage systems and even parotidectomy/submaxilectomy. The management and special features of iatrogenic salivary duct injury in patients with oral cancer who underwent head and neck reconstructive surgery has not been described yet. Material and …

Male breast cancer: Reconstructive surgery

2020

The conventional treatment for male breast cancer consists of modified radical mastectomy with axillary sentinel node biopsy and/or axillary lymph node dissection in case of lymph node-positive disease. However, breast-conserving surgery (BCS) is gaining popularity also among men. In both cases, surgery leaves an aesthetic disfigurement that impacts patient well-being and quality of life. Thus, even if male breast has a different social and emotional role than female’s one, male breast reconstruction deserves the same importance. The aim of this chapter is to give a comprehensive review on latest indications and strategies for the post-oncological reconstructive surgery of the male breast.

Oral Surgical Management of Bone and Soft Tissues in MRONJ Treatment: A Decisional Tree.

2020

Background: The aim of the present work was to analyze a 10-year retrospective series of surgically treated medication-related osteonecrosis of the jaws (MRONJ) cases, reporting the clinical outcome and success rate for each adopted procedure in order to draw a treatment algorithm that is able to standardize clinical decision making and maximize the success of oral surgical treatment of MRONJ. Methods: Different surgical approaches were categorized taking into consideration two variables a) hard tissue management (defined as debridement, saucerization or marginal resective surgery of maxillary necrotic bone) and b) soft tissue management (defined as type of flap design and related modality …

Primary Extracranial Meningiomas of the Head and Neck

2021

Meningiomas represent the most common benign histological tumor of the central nervous system. Usually, meningiomas are intracranial, showing a typical dural tail sign on brain MRI with Gadolinium, but occasionally they can infiltrate the skull or be sited extracranially. We present a systematic review of the literature on extracranial meningiomas of the head and neck, along with an emblematic case of primary extracranial meningioma (PEM), which provides further insights into PEM management. A literature search according to the PRISMA statement was conducted from 1979 to June 2021 using PubMed, Web of Science, Google Scholar, and Scopus databases, searching for relevant Mesh terms (primary …

Endothelial modulation of 5-hydroxytryptamine-induced contraction in goat cerebral arteries.

1993

Abstract 1. 1. In isolated goat middle cerebral artery segments, 5-hydroxytryptamine (5-HT, 10 −8 −3 × 10 −5 M) caused concentration-dependent contractions, with EC 50 = 2.1 (1.9−2.5) × 10 −7 M and E max = 60 ± 2% of 50 mM KCl-induced contraction. 2. 2. Mechanical removal of endothelium significantly increased the E max (91 ± 8%) and did not change the EC 50 value of 5-HT-elicited contractions. 3. 3. Incubation of unrubbed arteries with the irreversible inhibitor of EDRF, gossypol (10 −5 M), significantly increased the contractile response to 5-HT ( E max = 77 ± 4%). 4. 4. Incubation of unrubbed arteries with the competitive inhibitor of the NO synthesis, N G -nitro - l -arginine (L-NOARG) …

Microsurgical Scalp Reconstruction in the Elderly

2015

BACKGROUND Microvascular reconstruction is the mainstay of treatment in complex scalp defects. The rate of elderly patients requiring scalp reconstruction is increasing, but outcomes in elderly patients are unclear. The purpose of this study was to systematically review the literature pertaining to free tissue transfer for scalp reconstruction in patients older than 65 years to compare outcomes among different free flaps and determine the safety profile of treatment. METHODS A systematic review of the available literature of patients undergoing microvascular scalp reconstruction was completed. Details for patients 65 years and older were extracted and reviewed for data analysis. RESULTS A t…

An innervated retroauricular skin flap for total earlobule reconstruction.

2003

In this article, the authors describe a technique for total earlobule reconstruction in a patient who underwent earlobule excision for basal cell carcinoma. The reconstruction was by means of an innervated retroauricular skin flap, folded double. The flap presented preserved skin sensitivity over all the reconstructed area, which is compromised by those techniques using a cranially or medially based flap which lead to the reconstruction of an insensible earlobule. This is a very important aspect of this technique, especially for those who wear pendant earrings, since a non-sensitive lobule would be more vulnerable to traumas causing laceration. In addition, it allows a good aesthetic result…
