Usefulness of endonasal flaps and grafts in skull base surgery. Consensus document.

Introduction: Skull base reconstruction is one of the greatest challenges extended endonasal endoscopic surgery. Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes.

Research in Cerebrospinal Fluid Leak (Rhinorrhea and Otorrhea): A Bibliometric Analysis From 1945 to 2018.

Objective In this study, we aimed to analyze research activity on cerebrospinal fluid (CSF) leaks in general and CSF rhinorrhea and otorrhea in particular and to identify the main topic clusters in these areas. Methods We identified all relevant documents, using the medical subject heading (MeSH) term "Cerebrospinal Fluid Leak", that are indexed in the MEDLINE database between 1945 and 2018. We performed a descriptive bibliometric analysis and analyses of networks and research clusters in order to identify the main topic areas of research.

Three-Dimensional Reconstruction of the Sphenoid Sinus Anatomy for Presurgical Planning with Free OSIRIX Software.

 A preoperative three-dimensional (3D) surgical field understanding remains a key factor to achieve safer endonasal transsphenoidal endoscopic approaches (ETSE). The aim of this article is to describe how we can get a reliable 3D sphenoidal anatomical reconstruction for surgical planning by using a user-friendly, accurate, and free image software.  Free computer software (OSIRIX Medical Imaging Software) was used to create in a personal computer a three-dimensional (3D) reconstruction of the sphenoid sinus (SS) based on head computed tomography angiographies (CTAs) from a series of 67 patients who were operated for sellar tumors during a 4-year period (March 2016 to March 2020).

Top-cited articles in cerebrospinal fluid leak (rhinorrhea and otorrhea) (1945-2018).

Introduction: As scientific knowledge has grown in biomedicine, it has also become necessary to develop tools to manage and understand the body of evidence. In that sense, bibliometrics has become a consolidated discipline for analyzing scientific activity, enabling the characterization of a particular field or area of knowledge by means of the quantification of the bibliographic characteristics of scientific publications.

Objective: The objective of this study was to determine the most frequently cited articles in the field of cerebrospinal fluid rhinorrhea and otorrhea.

Endonasal endoscopic surgery in pituitary adenomas: Surgical results in a series of 86 consecutive patients.

Introduction: The endoscopic endonasal approach has become the gold standard for the surgical treatment of pituitary adenomas.

Objectives: The aim of this study is to present the results obtained in our hospital in purely endoscopic surgery of pituitary adenomas.

Methods: From February 2011 to August 2016, we conducted a prospective study on a series of 86 patients with pituitary adenoma, all of whom underwent surgery with a purely endoscopic endonasal approach.

Transsphenoidal Approach in Endoscopic Endonasal Surgery for Skull Base Lesions: What Radiologists and Surgeons Need to Know.

In the last 2 decades, endoscopic endonasal transsphenoidal surgery has become the most popular choice of neurosurgeons and otolaryngologists to treat lesions of the skull base, with minimal invasiveness, lower incidence of complications, and lower morbidity and mortality rates compared with traditional approaches. The transsphenoidal route is the surgical approach of choice for most sellar tumors because of the relationship of the sphenoid bone to the nasal cavity below and the pituitary gland above. More recently, extended approaches have expanded the indications for transsphenoidal surgery by using different corridors leading to specific target areas, from the crista galli to the spinomedullary junction.

[Pedicle flaps based on the sphenopalatine artery: anatomical and surgical study].

Introduction: Local pedicle flaps based on the sphenopalatine artery make it possible to reconstruct large defects of the skull base (SB).

Material And Methods: From January 2008 to January 2013, 64 lesions with involvement of SB were analysed. These lesions were treated using endoscopic endonasal approach and required a pedicle flap based on the sphenopalatine artery.

[Three-dimensional endoscopic endonasal study of skull base anatomy].

Introduction: Training in dissection of the paranasal sinuses and the skull base is essential for anatomical understanding and correct surgical techniques. Three-dimensional (3D) visualisation of endoscopic skull base anatomy increases spatial orientation and allows depth perception.

Objective: To show endoscopic skull base anatomy based on the 3D technique.

[Radiological anatomy of the ethmoidal arteries: CT cadaver study].

Introduction And Objectives: Our aim was to study the radiological anatomy of the ethmoidal arteries.

Methods: A descriptive study was performed including CT images of 20 cadaver heads. The specimens were perfused with a radiopaque material and various anatomical parameters were analysed.

Epidemiology of epistaxes admitted to a tertiary hospital.

Introduction And Objectives: Epistaxis has been known since antiquity. However, we have limited epidemiological data at our disposal. The aim of this study is to know the main epidemiological characteristics of the cases of epistaxis admitted and to determine the factors associated with the recurrence of bleeding.
