BACKGROUND: Pediatric nasolacrimal duct obstruction (PNDO) requires therapeutic intervention after conservative procedures failed. As resilient treatment guidelines for the treatment are missing, the aim of this study was to evaluate the advantages of two different intervention techniques in children with PNDO. METHODS: Between January, 2006 and June, 2014, 233 children (0-208 months) were treated either with conventional probing by ophthalmologists only (Group I) or with endonasal endoscopic interdisciplinary approach (Group II)...

BACKGROUND: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments. OBJECTIVE: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment...

BACKGROUND: Surgical access to Meckel's Cave (MC) is challenging due to its deep location and surrounding important neurovascular structures. Currently existing endoscopic endonasal (EE) approaches require dissecting near the internal carotid artery (ICA) or require transposition of the pterygopalatine neurovascular bundle. OBJECTIVE: To describe a novel approach to access the anterolateral aspect of the MC using a minimally invasive EE route. METHODS: The EE transmaxillary transinferior orbital fissure approach was simulated in 10 specimens...

A previous meta-analysis reported no benefit for silicone intubation during dacryocystorhinostomy. However, the power of this meta-analysis was 0.274. Therefore, the benefit of silicone intubation remains controversial. We undertook a cumulative meta-analysis to evaluate the success rate of dacryocystorhinostomy (DCR) with and without the use of a stent. Pubmed, EMBASE and the Cochrane Library were searched. Statistical power and trial sequential analyses were performed according to the result of the meta-analysis...

The endoscopic endonasal approach is considered an alternative minimally invasive approach for suprasellar craniopharyngiomas. However, the complicated surgical manipulations required by this approach have limited its application. We evaluate whether the approach features a learning curve. Thirty-three patients were retrospectively reviewed and grouped as early (17 patients) and late (16 patient) groups. The operation time, extent of removal, ophthalmology, endocrinology, reconstruction and modifications of standard technique were evaluated...

PURPOSE: Immediate postoperative imaging is frequently obtained after combined skull base surgery (SBS) with endoscopic endonasal and open transcranial approaches. The importance of early postoperative imaging for detecting complications in these patients is still debatable. In this study, we investigated the clinical utility of early postoperative imaging after combined SBS for determination of postoperative complications. METHODS: A retrospective chart analysis of 21 cases of combined SBS between 2009 and 2015 was performed...

The endoscopic endonasal approach (EEA) has been popularized in adults and has been applied to an expanding range of surgical modules and indications in this population. However, its clinical application in pediatric neurosurgery has been impeded by the differences in anatomical features and the relatively low incidence of diseases to which it is applicable. In this review article, we mainly discuss the surgical indications, feasibility, and complications of EEA for suprasellar lesions in children based on a review of the literature, focusing especially on the age-related anatomical features of the nasal cavity, various pathologic entities, and the impact of EEA on long-term craniofacial growth...

BACKGROUND: Major vessel hemorrhage in endoscopic, endonasal skull-base surgery is a rare but potentially fatal event. Surgical simulation models have been developed to train surgeons in the techniques required to manage this complication. This mixed-methods study aims to quantify the stress responses the model induces, determine how realistic the experience is, and how it changes the confidence levels of surgeons in their ability to deal with major vascular injury in an endoscopic setting...
