OBJECTIVE: Minimally invasive alternatives to the pterional craniotomy include the minipterional and the supraorbital craniotomy (SOC). The latter is performed via either an eyebrow or an eyelid skin incision. The purpose of this systematic review was to analyze the type and the incidence of approach-related complications of these keyhole craniotomies. METHODS: We review pertinent publications retrieved by search in the PubMed/Medline database. Inclusion criteria were all full-text publications, abstracts, and posters in English, up to 2016, reporting clinical results...

Tuberculum sellae meningioma remains a surgical challenge. Deep location of tumor, vascular and nerve encasement, and pituitary stalk involvement are the main technical issues. The frontopterional approach represents a natural, simple, and elegant approach to this area enabling surgeon to have a direct control on all anatomical structures. A 42-year-old woman was referred with a delayed diagnosis of tuberculum sellae meningioma due to the presence of HLA-B27-associated uveitis. She presented with 1/10 visual acuity in the left eye and no right visual function...

Retrochiasmatic craniopharyngiomas (RC) are a challenge for the neurosurgeon to treat surgically, restrained by their location in the interpeduncular fossa, surrounded by vital neurovascular structures, narrow corridor and poor visibility. Many approaches are possible and elucidated in the literature, which the surgeon chooses, based on multiple factors, such as the size of tumor, calcification, laterality, preoperative neurological deficits and the endocrine function status, recurrence, postradiotherapy status, or significant superior and/or posterior extension...

Craniopharyngiomas represent one of the most challenging brain tumors for the neurosurgeon. For most of the 20th century, these parasellar lesions have been approached via the classic open approaches of neurosurgery such as pterional, frontobasal, interhemispheric, and transpetrosal craniotomies. The endoscopic endonasal approach to these tumors, rather than craniotomy, has risen in popularity over the last two decades. Regardless of approach, a detailed knowledge of surgical anatomy and careful preoperative surgical planning are essential to achieve good clinical results; iatrogenic morbidity can potentially be severe due to hypothalamus, optic apparatus, and/or vascular injuries...

BACKGROUND: The pterional approach, along with its orbitopterional and orbitozygomatic extensions, is among the most common surgical approaches for tackling challenging aneurysms of the basilar artery apex (BAX). There is general consensus that the orbitozygomatic approach provides the best exposure for these lesions. However, there is little objective evidence to support approach selection for surgical treatment of BAX aneurysms. OBJECTIVE: To compare different features regarding surgical treatment of BAX aneurysms between the pterional, orbitopterional, and orbitozygomatic approaches...

PURPOSE: Lateral supraorbital approach is a simpler and quicker method than pterional approach. It provides a more anterior projection when compared to the pterional approach. There are some minor differences of the modified lateral supraorbital approach when compared to lateral supraorbital approach. It is directed more subfrontally and anterior than the pterional and lateral supraorbital approach. MATERIAL AND METHODS: We used modified lateral supraorbital approach in 100 cases between 2012 and 2015 in Medical Park İzmir Hospital/Turkey...

Mrityunjoy Sarkar, Ashok Pillai
BACKGROUND AND IMPORTANCE: The lateral suboccipital approach for microvascular decompression (MVD) of the trigeminal nerve has become a standard-of-care over the past several decades. Syndromic cranial base settling, a rare but known cause for trigeminal neuralgia (TN), poses significant dilemmas in clinical management. In such cases, distorted anatomy may render surgery via the suboccipital approach difficult or even impossible. CLINICAL PRESENTATION: A 34-yr-old male with osteogenesis imperfecta and severe basilar invagination suffered from TN that was refractory to medication and stereotactic radiosurgery...

BACKGROUND: Various approaches can be considered for decompression of the intracanalicular optic nerve. Although clinical experience has been reported, no quantitative study has yet compared the extent of decompression achieved by an endoscopic endonasal versus transcranial approach. OBJECTIVE: Toward this aim, our morphometric analysis compared both approaches by quantifying the circumferential degree of optic canal decompression that is possible before any meningeal violation, which would result in cerebrospinal fluid (CSF) leak...

Ririko Takeda, Hiroki Kurita
BACKGROUND: To reduce complications associated with conventional pterional craniotomy, a transsylvian keyhole approach for unruptured small anterior circulation aneurysms is proposed. METHODS: A 7-cm linear scalp incision is made along the hairline, beginning at the zygoma, followed by minimal temporal muscle dissection. Two burr holes are drilled out at McCarty's point and the temporal bone, and a 3-cm equilateral triangle bone flap is made, whose apex is located above the sylvian point...

BACKGROUND: Tentorial meningiomas are a broad and consistent category of tumors but their definition is still unclear and their classification uncertain. OBJECTIVE: To report the clinical and surgical characteristics of tentorial hiatus meningiomas based on a revised classification of tentorial meningiomas. METHODS: We reviewed the records of 14 patients who had undergone microsurgical removal of incisural tentorial meningioma. Two tumor subgroups, anterolateral (AL) and posteromedial (PM), were distinguished according to their site of attachment: the middle third and the posterior third of the tentorial free margin, respectively...

Giant "true" posterior communicating artery (PCOM) aneurysms are rare and the best surgical treatment for them is unclear. We present a case of 85-year-old woman with this type of lesion, 35 mm in diameter, successfully treated by trapping and thrombectomy via pterional approach without complications. There were no perforating arteries originating from the aneurysmal wall. The patient had an uneventful postoperative course. The key for successful treatment for such lesions is preservation of perforators, as trapping may result in ischemic complications...

We experienced an extremely rare case of a giant P1-P2 partially thrombosed aneurysm associated with bilateral ICA occlusion in a Klippel-Trenaunay syndrome patient. In our experience, direct surgical clipping via a pterional approach is generally favored for aneurysms located in the junction of the P1-P2 segments, even if they are giant.

We report the first case of two de novo miniature aneurysms(ruptured/unruptured)emerging from the infundibular dilatation(ID)of the callosomarginal artery, which branches from the infracallosal(A2)segment of the azygos anterior cerebral artery(AACA), in a 36-year-old woman. The patient had previously been diagnosed with a miniature, unruptured aneurysm, occurring in the A2 segment of the AACA, detected by CT angiography(CTA)at another hospital two years ago, and had been followed up with MR angiography(MRA)every 6 months...

Meningiomas of the clinoid region pose a formidable surgical challenge. Pterional craniotomy is the traditional approach and is often associated with high-risk postsurgical morbidities. In the current presentation, we describe an elderly male with a clinoidal meningioma who underwent a minimally invasive supraorbital craniotomy for tumor resection. Patient presentation, neuroimaging, and surgical techniques (patient position, incision, anatomic consideration, and surgical steps) are described meticulously. Initial intraoperative steps include dissection via the corridor between the carotid artery and the tentorium, as well as exposing the tumor in the opticocarotid triangle, followed by tumor dissection using microsurgical techniques...

BACKGROUND: A contralateral approach to clip a middle cerebral artery (MCA) aneurysm in case of bilateral intracranial aneurysms reduces surgical time and cost. However, there is a lack of evidence for objective patient selection. In this study, we assessed the change in surgical freedom along the contralateral MCA to provide objective evidence for patient selection. METHODS: Sixteen cadaveric specimens were studied. Through a pterional approach, the surgical freedom was calculated moving distally along the contralateral MCA at 5-mm increments...

Pilocytic astrocytomas (PAs) are seemingly innocuous and benign tumors. However, in recent times, many case series have documented high rates of hemorrhage in these neoplasms. We hereby provide a detailed analysis on hemorrhagic pilocytic astrocytomas (HPA) in adults and report one such case managed at our institute. In addition, salient differences between adult and pediatric hemorrhagic PA have been briefed. Hospital records were retrieved for our case. Literature review was conducted by searching online databases for the following keywords-pilocytic astrocytoma, hemorrhage, cranial, pediatric, and adults...

This video demonstrates a surgical technique of resecting dorsum sellae meningioma using a combined interhemispheric translamina terminalis approach and pterional approach with clinoidectomy. The tumor, 5 cm in maximum diameter, originated from the dorsum sellae, compressed the third ventricle and the midbrain, and displaced the pituitary stalk ventrally. Feeding arteries of the tumor were bilateral meningohypophyseal trunks, mainly from the right side. The authors performed devascularization of the tumor via a right pterional approach following frontotemporal craniotomy, and debulking of the tumor via an interhemispheric translamina terminalis approach following bifrontal craniotomy...

Tuberculum sella meningiomas can be approached through lateral approaches including pterional/orbitozygomatic craniotomies, frontobasal craniotomy, or through expanded endoscopic transsphenoidal approaches. The authors present the case of a 60-year-old male who presented with bitemporal hemianopia and significant right-side visual acuity compromise due to a large tuberculum sella meningioma. The tumor had an important extension to the posterior fossa. A right orbitozygomatic trans-sylvian approach was deemed most suitable to tackle the posterior extension of the tumor...

BACKGROUND: Schwannomas of the parasellar region may arise from the trigeminal, oculomotor, trochlear, and abducens nerves. OBJECTIVE: To define the tumor origin, location, and dural relationship (extradural vs extra-intradural vs cisternal) on preoperative magnetic resonance imaging (MRI), in order to plan the best surgical approach (purely extradural vs extra-intradural). METHODS: Twenty-four patients with parasellar schwannomas who underwent surgery were retrospectively analyzed...
