tuberculum sellae

Preoperative simulation for endoscopic endonasal approach(EEA)using computed tomography and magnetic resonance imaging evaluates tumor extension and the relationship between adjacent structure(the pituitary stalk, major vessels, and cranial nerves); therefore, preoperative planning of nasal procedure, skull base bony removal, and cranial base reconstruction are possible. Additionally, three-dimensional(3D)fusion image aids surgeons to visualize intraoperative 3D findings. These preoperative simulations are critical to avoid complications and predict pitfalls perioperatively...

BACKGROUND: Tuberculum sellae meningiomas (TSM) account for 3-10% of intracranial meningiomas. Visual loss is the presenting symptom in up to 80% of cases. Surgical management poses a great challenge due to tumor proximity to neurovascular structures such as the optic nerve and the internal carotid artery (ICA); hence, there is controversy regarding the optimal approach. The aim of this study is to determine differences in visual outcomes between transcranial (TCA) and endoscopic endonasal (EEA) approaches...

OBJECTIVE: Tuberculum sellae meningiomas (TSMs) usually compress the optic nerve and optic chiasma, thus affecting vision. Surgery is an effective means to remove tumors and improve visual outcomes. On a larger scale, this study attempted to further explore and confirm the factors related to postoperative visual outcomes to guide the treatment of TSMs. METHODS: Data were obtained from 208 patients with TSMs who underwent surgery at our institution between January 2010 and August 2022...

Tuberculum sellae meningiomas commonly present as bitemporal hemianopia and loss of visual acuity due to optic nerve compression. Two female patients (48 and 58 years old) presented with a small scotoma at the lower visual field center due to tuberculum sellae meningioma (25 and 10 mm, respectively). Despite the fact that their visual field defect was not very large, daily activities, including walking or reading were hindered. By the total removal of the tumors in both patients, the scotoma was cured and daily activities recovered...

A 9-year-old girl presented to our neurosurgery clinic complaining of visual disturbances for a week. Magnetic resonance imaging showed an extensive sellar lesion with suprasellar involvement and compression of the optic chiasm. Based on these findings, a cystic craniopharyngioma, a pituitary macroadenoma and - less likely - a Rathke's cleft cyst were considered as differential diagnoses. In view of the progressive loss of vision, the parents agreed to resection of the lesion through an endoscopic endonasal transtubercular approach, with the aim of a gross total resection...

OBJECTIVE: In this prospective non-randomized study we reported our experience related to planum sphenoidale (PS) and tuberculum sellae (TS) meningiomas in a similar cohort of patients operated via the endonasal or the supraorbital route. A comprehensive quality of life analysis has been performed. METHODS: Being comparable in general features, between November 2017 to January 2020, a total of 20 patients with anterior skull base meningioma were included. Hence, 10 patients were treated using the supraorbital keyhole procedure (SO) while 10 patients received an endoscopic endonasal approach (EEA)...

BACKGROUND: Tuberculum sellae (TS) meningioma is one of the most frequent meningiomas of the anterior skull base. Herein we perform a review of the literature concerning the preferred surgical approaches to TS meningiomas; in addition, we describe two explicative cases, operated on by our group using different approaches, with the aim to critically revise surgical indications and contraindications. METHODS: In October 2021, two female patients with tuberculum sellae meningioma were treated at the Policlinico Gemelli of Rome...

OBJECTIVE: Tuberculum sellae meningiomas (TSMs) are typically in the proximity of the optic nerves and the optic chiasm, thus making the primary aim of surgery the enhancement or stabilization of the patients' visual acuity. The authors therefore undertook a retrospective review of their 17-year experience with the pterional approach to ascertain the resection rate, neurological outcome, and visual outcome. METHODS: Patients who underwent TSM surgery between September 2003 and December 2020 at the authors' institution were retrospectively evaluated...

Tuberculum sellae meningioma (TSM) is a challenging tumor that grows close to several crucial structures, such as the optic nerve, arteries, and pituitary. Surgical treatment is currently evolving from a transcranial microsurgical resection to a transsphenoidal approach. This study examined the clinical profile of patients with tuberculum sellae meningioma and explored its relationship with scoring systems. This retrospective observational study included patients with TSM who underwent surgery at the Department of Neurosurgery at our hospital between 2017 and 2022...

Basilar invagination (BI) is characterized by rostral dislocation of the cervical spine toward the skull base. The craniometrics of the skull base have shown significant differences among craniocervical junction malformations. The sphenoid bone is the center of the skull base; however, no study has evaluated this bone in cases of BI. This was a cross-sectional study of MRI databanks from two institutions of the author's practice between 1985 and 2020. The craniometrics of the sphenoid bone were measured in BI patients and controls...

A 25-year-old woman presented with exophthalmos. With the diagnosis of dural arteriovenous fistula of the transverse sinus, the patient underwent coil embolization. Fifteen years later, she sustained visual disturbance due to de novo tuberculum sellae meningioma that was resected. Surveillance magnetic resonance imaging (MRI) performed at the age of 42 years detected tumor recurrence and small, apparent meningioma in the cerebral convexity. The patient underwent the second tumor resection at the age of 46 years...

OBJECTIVE: Tuberculum sellae meningioma (TSM) represents a complex skull base tumor. The primary goals of surgical treatment are represented by maximal safe resection and visual recovery; therefore, appropriate patient selection is critical to optimize results. In the last 2 decades, the endoscopic endonasal approach (EEA) has appeared as a successful and viable strategy for the management of these tumors. The authors identified preoperative factors associated with extent of resection and visual outcome after EEA for TSM...

INDICATIONS CORRIDOR AND LIMITS OF EXPOSURE: Ideal indications for tuberculum sellae meningiomas (TSM) removal through endoscopic endonasal approach (EEA) are midline tumors (<3.5 cm), possibly with no optic canal invasion and no vessels encasement. The EEA is favored by a wide tuberculm sellae (TS) angle and a deep sella at the sphenoid sinus (SS).1 Adequate removal of paranasal structures provides a wider surgical corridor ensuring exposure at the suprasellar area and safe instruments manuevrability...

OBJECTIVE: Phenytoin is commonly prescribed to prevent postoperative seizures. Despite the rarity of the CYP2C9 genetic polymorphism, which may result in poor phenytoin metabolism, in the Thai population, the authors report a case of phenytoin toxicity in a patient with poor metabolism administered with a standard dose of phenytoin. CASE REPORT: A 58-year-old Thai woman presented to the outpatient clinic with a 2-day history of nausea, vomiting, and dizziness. She underwent craniotomy for tumor removal 2 weeks after being diagnosed with tuberculum sellae meningioma...

Optic canal unroofing (OCU) has gradually become a routine technique for tuberculum sellae meningiomas (TSMs) resection. This meta-analysis aimed to evaluate the efficacy and safety of OCU. A systematic review and meta-analysis of the published literature on this topic from 2003 to 2023 were conducted in accordance with the PRISMA guidelines. Rigorous statistical analysis with a p-value was performed for related change in visual improvement, gross total resection (GTR), visual deterioration, and olfactory nerve damage...

INTRODUCTION: The sella turcica is one of the important landmarks of lateral cephalometry, which is used in orthodontics for the diagnosis, treatment plan, and evaluation of skeletal development and maturity. The purpose of the present study is to investigate the relationship between the dimensions and morphology of sella turcica with the long-face growth pattern and people with an open bite. This study also examines the relationship between sella turcica bridging (STB) and the vertical growth pattern...
