BACKGROUND: The catastrophic and rare nature of an internal carotid artery (ICA) injury during endonasal surgery limits training opportunities. Cadaveric and animal simulation models have been proposed, but expense and complicated logistics have limited their adoption. Three-dimensional (3D) printed models are portable, modular, reusable, less costly, and proven to improve psychomotor skills required for managing different lesions. In this study we evaluate the role of a simplified laser-sintered model combined with standardized training in improving the effectiveness of managing an ICA injury endoscopically...

INTRODUCTION: Cerebrospinal fluid (CSF) leak is a common complication after surgeries involving sellar reconstruction. Various techniques, such as the nasoseptal flap, have been developed in order to limit the rate of post-operative CSF leak. However, the nasoseptal flap causes a number of complications due to donor site morbidity. A free mucosal graft may be just as effective in reducing CSF leaks as well as reducing postoperative nasal discomfort. This study aims to assess the operative outcomes of the free mucosal graft after pituitary resection...

Pituitary surgery is performed via a transsphenoidal approach in the vast majority of cases according to various methods that have changed over the years. A microscopic transseptal approach via a sublabial mucosal incision or a nasal mucosal incision has also been extensively used. An endoscopic transnasal approach was first described in the 1990's, followed by the concept of a microscopic transseptal approach and an endoscopic strictly endonasal approach. We use an entirely endoscopic transseptal transsphenoidal approach via an incision in the nasal mucosa for both access and tumour resection...

BACKGROUND: Endoscopic skull base surgery continues to evolve in its indications, techniques, instrumentation, and postoperative care. As surgery of the skull base will often violate dura, intraoperative and postoperative cerebrospinal fluid (CSF) leak is not uncommon and represents a potential conduit for air and bacterial contamination. Patients with obstructive sleep apnea (OSA) requiring continuous positive airway pressure (CPAP) therapy undergoing skull base surgery represent a challenging group...

Image enhancement is used widely in endoscopic sinonasal surgery. It is yet to be established whether image enhancement has advantages over white-light endoscopy. The authors aimed to evaluate the preferences and subjective visual perception of image enhancement in diagnostic images acquired at the beginning of endonasal endoscopic surgeries. An online survey consisting of 12 endoscopic images, 4 enhanced with Clara mode, 4 enhanced with Chroma mode, and 4 enhanced with Clara+Chroma mode, was distributed. The enhanced images were randomly presented with nonenhanced white-light images...

We report a case of a young male who received multiple surgical treatments for repeated recurrence of skull base mesenchymal chondrosarcoma (MC). When the patient was 18 years old, we subtotally removed the skull base MC and he was treated with stereotactic radiosurgery for remnant tumors in the left cavernous sinus. After 30 months, we removed residual tumors that had regrown partially, via combined endonasal endoscopic and orbitozygomatic approaches. Over the next 65 months, the patient refused radical resection, and received six salvage surgeries, two stereotactic radiotherapies, and five stereotactic radiosurgeries for repeated recurrence...

INTRODUCTION: Functional endonasal endoscopic surgery is a frequent surgical procedure among otorhinolaryngologists. In 2014, the European Society of Rhinology published the "European Position Paper on the Anatomical Terminology of the Internal Nose and Paranasal Sinuses", aiming to unify the terms in the English language. We do not yet have a unified terminology in the Portuguese language. OBJECTIVE: Transcultural adaptation of the anatomical terms of the nose and paranasal cavities of the "European Anatomical Terminology of the Internal Nose and Paranasal Sinuses" to Portuguese...

OBJECTIVES/HYPOTHESIS: Although transnasal endoscopic resection (TER) of juvenile angiofibroma (JA) is unquestionably less invasive than traditional external approaches, several endonasal and neurovascular structures are sacrificed during the procedure. The aim of this study was to evaluate long-term neurological morbidity and related quality of life following TER of JA. STUDY DESIGN: Retrospective cohort study. METHODS: All patients who underwent TER for JA at the Unit of Otorhinolaryngology-Head and Neck Surgery of the University of Brescia from 1994 to 2016 were contacted to know their availability to undergo a battery of tests aimed to assess lacrimal secretion (Schirmer test), impairment of sensitive nerves (electrophysiological threshold test), and impact on quality of life of tearing reduction and sensitivity impairment with the Ocular Surface Disease Index (OSDI) and visual analogue scale (VAS) (0-10), respectively...

Postoperative visual function is a major concern in transsphenoidal surgery (TSS). Although several reports have demonstrated the importance of visual evoked potential (VEP) monitoring during TSS, the usefulness of VEP monitoring have been controversial because of its reproducibility. Efficacy of VEP was analyzed in 20 consecutive cases of patients who underwent endoscopic endonasal TSS surgery. We adapted a high-power light-emitting diode stimulator with electroretinography using venous anesthesia. In addition, we used black shield patch and braided codes to obtain reproducible VEP amplitudes...

Background: Pediatric patients presenting with a nasal mass is uncommon and a high index of suspicion for it to be a meningoencephalocele is essential. Majority of these are congenital and require early intervention owing to the risk of meningitis. Surgery in these cases is very challenging because of the risk of anesthesia and limited space. Objective: This study aimed to describe our technique and experience in managing pediatric meningoencephaloceles. Methods: A retrospective study of 19 pediatric patients (age ranging from 40-day-old infants to 11...

BACKGROUND: Cerebrospinal fluid (CSF) rhinorrhea from a lateral skull base defect refractory to spontaneous healing and/or conservative management is most commonly managed via open surgery. The approach for repair is dictated by location of the defect, which may require surgical exploration. The final common pathway, however, is the Eustachian tube (ET). Endoscopic ET obliteration (EETO) via endonasal and lateral approaches are under development. OBJECTIVE: While the anatomy of the ET has been studied, surgical landmarks have not been previously described or quantified...
