Multidisciplinary approach to anaplastic and metastatic meningioma: A case report and review of the literature.

Background: Meningiomas are slow-growing neoplasms, accounting for 20% of all primary intracranial neoplasms and 25% of all intraspinal tumors. Atypical and anaplastic meningiomas are infrequent, representing fewer than 5% of all meningiomas. Unusually, they can show aggressive behavior, and extracranial metastases are extremely rare, representing approximately 0.

Microsurgical free flaps for skull base reconstruction following tumor resection: Available techniques and complications.

Introduction: Resection of malignant tumors located in the anterior and middle fossae of the skull base requires thorough anatomical knowledge, as well as experience regarding the possible reconstructive options to resolve the resulting defects. The anatomical and functional relevance of the region, the complexity of the defects requiring reconstruction and the potential complications that can occur, represent a true challenge for the surgical team. The goal of this study is to describe the microsurgical reconstructive techniques available, their usefulness and postoperative complications, in patients with malignant tumors involving the skull base.

Giant Cell Tumor of the Carotid Body: A Rare Tumor with Malignant Potential.

Introduction: Carotid body tumors (CBTs) are certainly unusual. They are vascular lesions originating from paraganglionic cells, located at the common carotid artery (CCA) bifurcation. They represent less than 0.

Recommendations regarding emergency head and neck procedures during coronavirus disease-2019.

The coronavirus disease-2019 (COVID-19) has spread globally and is considered a world health emergency. Healthcare professionals represent an important percentage of the infected population, with otolaryngologists and head and neck surgeons at particular risk. Elective procedures have been strongly discouraged, but urgent disorders still entail a hazardous setting.

[Tongue squamous cell carcinoma and bilateral kidney metastases].

Squamous cell carcinoma of the tongue is the most common malignant tumor of the oral cavity. The finding of metastases, in this type of cancer, is considered the main factor of poor prognosis with a marked effect on the overall survival. The normal progression tends to be locoregional, at the surgical site or regional lymph nodes, and systemic involvement is usually uncommon.

Head and neck sarcomas: treatment outcomes in a tertiary referral center in Argentina.

Purpose: To analyze the clinical findings, management, and results of oncological treatments and to identify prognostic factors in patients diagnosed with head and neck sarcoma.

Methods: We performed a retrospective analysis including 48 adult patients with primary head and neck sarcomas, treated between 2006 and 2018 in a referral center of Argentina.

Results: The median follow-up time was 44 months (range: 4-146 months).

Clear cell odontogenic carcinoma: a rare pathology with an innovative resolution.

Clear cell odontogenic carcinoma (CCOC) is an uncommon condition that has been considered malignant since 2005. The clinical presentation usually involves an asymptomatic swelling, which typically affects the anterior mandible in middle-aged women; it has neither clinical nor radiological defining features. Immunohistochemical analysis usually aids diagnosis, as clear cells are also associated with other clear cell carcinomas and benign tumors.

Treatment for postchemoradiotherapy hypopharyngeal stenosis: Pharyngoesophageal bypass using an anterolateral thigh flap-A case report.

Radiation-induced pharyngoesophageal stenosis is a frequent and unwanted consequence of nonsurgical treatment of hypopharyngeal carcinomas. Current treatment mainly includes endoscopic dilatations, but a poor response to this modality and/or a severe stenosis may lead to a radical resection (pharyngolaryngectomy) and reconstruction with tubed flaps, which allow oral feeding but fail to preserve speech. In this report, we present a case of radiation-induced hypopharyngeal stenosis treated with a pharyngoesophageal bypass using an anterolateral thigh (ALT) flap with the intention of preserving the larynx.

Reconstruction of Hind and Mid-Foot Defects after Melanoma Resection Using the Reverse Sural Flap: A Case Series.

 Melanoma resection creates important soft tissues defects, which are difficult to manage when located on the weight-bearing heel and mid foot. There is little evidence on the use of the reverse-flow sural flap for this type of reconstruction.  This study reports our case series on the reconstructive management of the hind and mid-foot defects after melanoma resection using the reverse sural artery flap.

Management Issues in the Treatment of an Ameloblastoma with an Atypical Presentation.

Benign ameloblastoma (BA) is the most common tumor arising from the odontogenic epithelium. Surgical resection with adequate margins is the mainstay of treatment due to the high index of tumor recurrence when not completely excised. Although locoregional spread has been described in the literature, it is very uncommon.

Treatment of edentulous mandibular fractures with rigid internal fixation: case series and literature review.

The aim of the study is to analyze the effectiveness of rigid internal fixation (RIF) for treating edentulous mandibular fractures. Because of the low incidence of fractures in edentulous mandible, there is no consensus of the optimal treatment for it. This study included all edentulous patients with mandibular fracture diagnosis, who were treated with internal fixation at the Hospital Italiano de Buenos Aires from November 1991 to July 2011.

Free flap reconstruction for complex scalp and forehead defects with associated full-thickness calvarial bone resections.

Extensive defects of the scalp and forehead associated with calvarial bone resections demand complex reconstructions. Free flaps offer vascularized tissue of excellent quality and quantity. We report six patients with extensive scalp and forehead defects associated with calvarial bone resections reconstructed with free flaps.
