BACKGROUND Sinonasal inverted papillomas (IPs) can be associated synchronously or metachronously to invasive squamous cell carcinoma (SCC) in 5% to 10% of cases. The purposes of the present study were to analyze the outcomes of patients with sinonasal SCC arising from inverted papilloma (IP-SCC) treated through an endoscopic approach and review the(More)
The extra-skeletal form is an unusual type of Ewing sarcoma (ES) arising from soft tissue and in the literature there are reports of less than 50 patients describing the tumor in the paranasal sinuses and skull base. The histological diagnosis is crucial to plan the correct treatment and the molecular confirmation is mandatory in equivocal patients. A(More)
INTRODUCTION Dermoids of the Eustachian tube are rare benign developmental tumours that typically occur in female children. General consensus of classification and nomenclature has still not been reached. The treatment of choice consists of a radical surgical excision. Several approaches have been described and few cases are reported in literature. A gross(More)
Orbital approaches provide significant trajectory to the skull base and are used with differently designed pathways. The aim of this study is to investigate the feasibility of a combined transorbital and transnasal approach to the anterior and middle cranial fossa. Cadaveric dissection of five silicon-injected heads was used. A total of 10 bilateral(More)
BACKGROUND The pterygopalatine fossa (PPF) is a difficult area to access, as it has been traditionally treated by external approaches. The development of endoscopic transnasal approaches enables surgeons to reach this region through a minimally invasive route, reducing the associated morbidity. METHODS We conducted a retrospective review of patients with(More)
Superior orbital fissure and orbital apex lesions are challenging to manage, regardless of the approach chosen, due to the potential morbidity. The objectives of this study are to describe an innovative, minimally invasive surgical approach addressing this critical area and to discuss its indications and outcomes. A young patient presented with visual(More)
OBJECT For several decades, the exclusive purpose in the management of anterior skull base malignancies has been to increase survival rates. Recently, given the improved prognosis achieved, more attention has been focused on quality of life (QOL) as well. Producing data on QOL in anterior skull base cancers is hampered by the rarity of the neoplasm and the(More)
BACKGROUND Despite the development of functional endoscopic endonasal surgery, there are still areas of the maxillary sinus that remain technically difficult to access using a standard middle meatal antrostomy as well as deep-seated skull base lesions requiring expanded transmaxillary approaches. METHODS All patients who underwent transnasal endoscopic(More)
