Surgical management of advanced sinonasal cancer: a 10-year mono-institutional experience.

Objective: Endoscopic endonasal surgery is effective in the treatment of sinonasal cancers. However, in cases of well-differentiated locally advanced neoplasms as well as recurrences, the most appropriate treatment is debated. The purpose of this study is to report a mono-institutional experience on craniofacial surgery performed in a tertiary-care referral centre.

Nasoseptal flap with extended pedicle dissection based on the maxillary artery: Clinical series of 55 cases.

Nasoseptal flap with extended pedicle dissection is a low morbidity and high success rate flap. It is a flap that can be applied to reconstruct a wide range of ipsilateral skull base defects.

Lateral Orbitotomy Cryo-Assisted Removal of Orbital Cavernous Hemangiomas: Case Report and Technical Hints.

Orbital cavernous hemangiomas are the most common adult benign vascular orbital neoformation, representing 5%-15% of all orbital masses, and may involve the extraconal or intraconal space. According to the International Society for the Study of Vascular Anomalies, orbital cavernous hemangiomas should be classified as low-flow nondistensible venous malformations and are characterized by slow growth, generally 0.2 cm/year.

Sinonasal Malignancies Involving the Frontal Sinus: A Mono-Institutional Experience of 84 Cases and Systematic Literature Review.

Frontal sinus involvement by malignant tumors is a rare finding. Therefore, a systematic literature review along with a personal case series may contribute to defining more accurately the epidemiology, treatment options, and outcomes of these neoplasms. This is a retrospective review of patients affected by frontal sinus malignancies surgically treated in a tertiary-care referral center over a period of 20 years.

Surgical Approaches for Possible Positions of an Olfactory Implant to Stimulate the Olfactory Bulb.

Introduction: Current scientific developments seem to allow for an "olfactory implant" in analogy to cochlear implants. However, the position and surgical approaches for electrical stimulation of the olfactory system are unclear.

Methods: In a human anatomic cadaver study, we investigated different endoscopic approaches to electrically stimulate the olfactory bulb (OB) based on the following considerations: (1) the stimulating electrode should be close to the OB.

Patterns of recurrences in sinonasal cancers undergoing an endoscopic surgery-based treatment: Results of the MUSES* on 940 patients: *MUlti-institutional collaborative Study on Endoscopically treated Sinonasal cancers.

Objectives: The improvements in survival with expansion of the survivors' population, along with evolution of endoscopically-based treatment modalities, have contributed to emphasize the clinical relevance of recurrences in sinonasal cancers. However, at present, literature is scant regarding the pattern of recurrences and the therapeutic strategies available to manage long survivors who experienced single or multiple failures. The aim of the present study was to analyze sinonasal cancers recurrences to provide data regarding rates and patterns of relapse, predictors of failure and prognostic impact of the recurrence.

Maxillary Sinus Floor Infiltration: Results From a Series of 118 Maxillary Sinus Cancers.

Objectives/hypothesis: Maxillary cancers are rare and aggressive tumors, which can spread beyond the sinus bony walls. Preoperative assessment of infiltration of maxillary sinus floor (MSF) is paramount for surgical planning, as palatomaxillary demolition significantly impacts patients' quality of life. This study investigates the challenges involved in the preoperative and intraoperative evaluation of MSF infiltration and analyzes its prognostic relevance.

Modified Posterior Pedicle Middle Turbinate Flap: An Additional Option for Skull Base Resurfacing.

Objectives/hypothesis: Although the Hadad-Bassagusteguy flap represents the first choice for middle and posterior skull base reconstruction and coverage of exposed bony areas, in some cases it is unavailable. The aim of this study is to describe, as an alternative option in selected cases, a modified posterior pedicle middle turbinate flap (mPPMTF) extended to the lacrimal area. Anatomical features, step-by-step harvesting technique, and surgical applications are presented.

Emergency endovascular treatment of cavernous internal carotid artery acute bleeding with flow diverter stent: a single-center experience.

Background And Objective: To describe our single-center experience in the treatment of cavernous internal carotid artery (ICA) acute bleeding with flow diverter stent (FDS), as a single endovascular procedure or combined with an endoscopic endonasal approach.

Methods: We analyze a case series of 5 patients with cavernous ICA acute bleeding, i.e.

Changing paradigms in sinus and skull base surgery as the COVID-19 pandemic evolves: Preliminary experience from a single Italian tertiary care center.

Background: Italy was the first European country suffering from COVID-19. Health care resources were redirected to manage the pandemic. We present our initial experience with the management of urgent and nondeferrable surgeries for sinus and skull base diseases during the COVID-19 pandemic.

Giant Merkel cell carcinoma of the lower limb: case report and review of the literature.

Background: Merkel cell carcinoma (MCC) is a rare cutaneous neuroendocrine malignancy that usually grows rapidly at the head and neck. Giant forms at the lower limbs are rarely reported and usually affect patients in the eighth decade or older.

Methods: We report the case of a 60-year-old man who presented with a giant MCC on his right thigh.
