BACKGROUND: The anatomical locations involved in trigeminal schwannomas (TSs) are quite complex. The endoscopic endonasal approach provides a minimal damage access corridor to both anterior and middle skull base for surgery. Given the nerve function recovery and postoperative neurological deterioration varied in different reports, the author demonstrates his surgery tips and the functional outcomes under endoscopic surgery in one single institution. METHODS: A retrospective review of patients with TSs was undertaken to assess the outcome of endoscopic surgery from 2006 to 2016...

OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

BACKGROUND: Epiphora has a significant impact on the patient's quality of life and is commonly caused by nasolacrimal duct obstruction. Dacryocystorhinostomy (DCR) has traditionally been performed via an external approach, which involves a skin incision. With the advent of endoscopes, the endonasal approach to DCR has gained significant popularity. METHOD: To prospectively compare the quality of life of adult patients who underwent either an endonasal or an external DCR for acquired nasolacrimal duct obstruction, the Lacrimal Symptom Questionnaire (Lac-Q) was administered before and after surgery...

Tension pneumocephalus is a rare but dangerous complication of craniotomy, sinus surgery, and traumatic cranial injury. Compared with simple pneumocephalus, which often resolves spontaneously over the course of a few days, tension pneumocephalus tends to increase with ongoing cerebrospinal fluid leak and requires immediate neurosurgical treatment to prevent cerebral herniation. Air transport of patients with tension pneumocephalus for neurosurgical care entails a risk of neurologic worsening because of changes in ambient air pressure with altitude and cabin pressurization...

OBJECTIVE: The endoscopic endonasal approach to the anatomically complex lateral skull base presents technical challenges. The use of the Eustachian tube as a landmark to identify the petrous internal carotid artery has recently been reported, and this study aims to define the anatomical relationship between the Eustachian tube and its surrounding structures using cadaveric dissection and radiologic analysis. METHODS: To clarify the relationship of the Eustachian tube with its surrounding structures, we performed endoscopic and microscopic dissection of four adult cadaveric heads, and analyzed computed topography scans from 20 patients...

OBJECTIVE: This report examines the utility of the preoperative image to orientate the surgeon in the sphenoid sinus during an endoscopic endonasal transsphenoidal approach (ETSS). METHODS: ETSS was performed in 100 cases of sellar lesion and used to classify the sphenoid sinus septum shape. Preoperative CT and MRI scans were taken for two types of coronal imaging: conventional and oblique. Expected sphenoid sinus septum shape was compared with those from ETSS to estimate concordance...

BACKGROUND: We report a rare case of hemorrhagic cavernous sinus hemangioma with sudden onset of abducens palsy. CASE DESCRIPTIONS: Sudden onset of diplopia occurred in a 49-year-old female. Head computed tomography (CT) findings revealed a high density mass in the right cavernous sinus with protrusion to the sphenoid sinus. Endoscopic endonasal surgery was performed, though early recurrence was noted. A gamma knife surgical procedure was then performed to prevent early recurrence after histopathological confirmation of cavernous sinus hemangioma...

Tension pneumosella (TP) is a rare entity reported as the invagination of the sphenoid sinus mucosa into the skull base after endonasal transsphenoidal surgery. Few studies have reported on TP, and in these studies, invagination is confined to either the intrasellar or suprasellar area. We encountered a case of unexpected prominent TP toward the intracranial space 5 years after endoscopic endonasal transsphenoidal surgery (EETS) for a nonfunctioning pituitary adenoma. In addition, we present a hypothesis of the underlying mechanism by a pressure gradient change between the extracranial and intracranial space in TP formation...

This report describes a bilateral sphenoid sinus mucosal flap for the repair of a sellar floor defect and CSF leak following endoscopic endonasal skull base surgery. The key advantage of this technique is enabling the sphenoid mucosal flaps to remain vascularized, which reduces postoperative complications including CSF leakage, recurrent sinusitis, meningitis, encephalitis and pneumocephalus. The use of this technique is a viable and possibly favorable alternative to free grafts in the reconstruction of small to medium sized sellar defects with low flow or absent CSF leaks base surgery...

Endoscopic endonasal surgery, an innovative surgical technique, is used to approach sinus lesions, lesions of the skull base, and intradural tumors. The cooperation of experienced otolaryngologists and neurosurgeons is important to achieve safe and reliable surgical results. The bath plug closure method is a treatment option for patients with cerebrospinal fluid(CSF)leakage. Although it includes dural and/or intradural procedures, surgery tends to be performed by otolaryngologists because its indications, detailed maneuvers, and pitfalls are not well recognized by neurosurgeons...

Chronic nasal dysfunction is a clinical concept in the diagnostic and therapeutic management of sinonasal diseases, based on the evo-devo theory of formation of the nose according to which the nose is not a single organ but rather an association of three organs: olfactory nose, respiratory nose and paranasal sinuses. In chronic nasal dysfunction theory, etiological diagnosis takes account of the possible pathophysiological independence of nasal symptoms, in accordance with the different origins and physiology of the three organs constituting the nose...

INTRODUCTION: supratentorial cavernous hemangiomas, particularly those found in the sellar region, are extremely rare. We present a case of sellar cavernous hemangioma with radiological characteristics that have never been reported. Due to the difficulty diagnosing these lesions, misdiagnosis might occur. Thus, briefing surgeons about the clinico-radiological features of such rare lesions is crucial for better understanding the enigmatic features of such rare lesions and to develop early management approaches that could result in better surgical excision with a lower tendency for complications...
