BACKGROUND: Skull base injury is an infrequent complication during endoscopic sinus surgery (ESS). We hypothesize that late recognition and repair of CSF leaks during ESS is associated with increased neurologic morbidity. METHODOLOGY: A retrospective review was performed of patients with skull base injury during ESS at a tertiary center from 1999-2015. The study population was separated into early (less than 72 hrs) and late (more than 72 hrs) intervention groups...

BACKGROUND: Endoscopic repair of anterior skull-base defects has become the gold standard for management of cerebrospinal fluid (CSF) rhinorrhea. Both improved techniques and adjuvant therapies have led to accepted success rates of greater than 90%. As management has evolved, shorter hospitalizations have been required and the goal of this study is to analyze the outcomes of patients repaired on an outpatient basis vs those managed as inpatients postoperatively. METHODS: Patients undergoing endoscopic repair of CSF rhinorrhea between 2004 and 2014 were identified by review of medical records...

The objective is to assess whether free middle turbinate (FMT) graft reconstruction, after endoscopic endonasal pituitary surgery, combines an acceptably low post-operative cerebrospinal fluid (CSF) leak rate with acceptable rhinological morbidity. This study identified 50 patients who underwent endoscopic endonasal pituitary surgery by the senior author in our teaching hospital between May 2011 and June 2012. FMT graft reconstruction was used in 32 cases. 18 patients were judged pre-operatively as not suitable for FMT reconstruction according to a novel skull base reconstructive algorithm...

BACKGROUND: The impact of failed cerebrospinal fluid leak (CSF) leak repair in endoscopic skull base surgery has not been adequately studied. METHODS: In this investigation we reviewed patients who had undergone endoscopic skull base surgery between 2002 and 2014 at 7 international centers. Demographic variables, comorbidities, tumor characteristics, and repair techniques were evaluated to determine association with successful repair of CSF leak. Postoperative complications and length of stay were compared among groups...

OBJECTIVE: Anterolateral skull base surgery to sellar and parasellar region has always represented a technical challenge for neurosurgeons. The microscopic endoscope-assisted trans-maxillo-sphenoidal approach (MEMSA) affords a direct surgical corridor free from critical skull base structures. The aim of this study is to describe and critically evaluate its application to access the sellar and parasellar areas in terms of surgical exposure and operability. METHODS: Six cadaveric heads were examined...

BACKGROUND: The collection of the greatest possible amount of pathological tissue is of paramount importance in neurosurgery to achieve the most accurate histopathological diagnosis, by performing all the necessary biomolecular tests on the pathological specimen, and to collect biological material for basic or translational science studies. This problem is particularly relevant in pituitary surgery due to the possible small size and soft consistency of tumors, which make them suitable for removal through suction, reducing the amount of available pathological tissue...

BACKGROUND: Endoscopic endonasal surgery to access the anterior skull base has evolved in many centres worldwide and provides a minimally invasive alternative, with better patient experience, to open techniques. METHOD: We present a basic approach to a midline lesion that is the fundamental starting point for wider access to the skull base. CONCLUSION: The nuances of this technique illustrated here have been developed in many centres to provide a safe procedure that has a low incidence of complications and excellent potential...

Ossifying fibroma is a rare benign osteogenic neoplasm arising from undifferentiated cells of the periodontal ligament. Ossifying fibroma have a well-defined border that differentiates it from fibrous dysplasia clinically; these tumors manifest as a round or ovoid, expansile, painless, slow-growing mass may displace the roots of adjacent teeth and also cause root resorption. A variety of approaches for resection of the maxilla have been described. Most involve the use of facial and lip-splitting incisions to gain wide access...

AIM: Olfactory groove meningiomas make 4 to 13% of meningiomas. The first line treatment of meningiomas is surgery but the extent and types of approaches advised for olfactory groove meningiomas are diverse, and include from aggressive skull base approaches to standard or minimally invasive craniotomies and endoscopic approaches. We retrospectively reviewed our series of olfactory groove meningiomas which were operated microsurgically by standard pterional or unifrontal approaches. MATERIAL AND METHODS: Our series of 61 olfactory groove meningioma patients operated through pterional or unifrontal approaches between March 1987 and September 2015 is reviewed and the clinical data, radiological findings, surgical treatment and clinical outcomes of the patients are retrospectively analyzed...

OBJECTIVE Endoscopic surgery has revolutionized surgery of the ventral skull base but has not yet been widely adopted for use in the cerebellopontine angle. Given the relatively normal anatomy of the cerebellopontine angle in patients with trigeminal neuralgia (TN), the authors hypothesized that a fully endoscopic microvascular decompression (E-MVD) might provide pain outcomes equivalent to those of microscopic MVD (M-MVD) but with fewer complications. METHODS The authors conducted a single-institution, single-surgeon retrospective study with patients treated in the period of 2006-2013...

BACKGROUND AND PURPOSE: In case of dehiscenses developing on the anterior scull base, complete closure resulting in the cessation of the communication between the nasal cavity and the intracranial space is mandatory as soon as possible, in order to prevent serious complications. With the development of the endoscopic techniques, the endonasal management for the reconstruction has become available in recent decades. METHODS: We aim to present the reconstruction techniques applied in our department in the cases of two patients recently operated at our institute...

The introduction of modern endoscopy in neurosurgery brought light to one of the darkest areas: the skull base. In particular, the trans-nasal route allowed skull base surgeons to visualize and dominate the entire midline skull base. We analyzed our surgical series of 199 patients that were affected by several pathologies (pituitary adenomas, clivalchordomas, craniopharyngioma, Rathke's cleft cysts, tuberculum sellaemeningiomas, and craniovertebral junction pathologies with bulbar compression) and treated each by using a 3D-HD endoscope between December 2012 and December 2015 and reviewed the literature...
