PURPOSE: Transsphenoidal surgery(TSS) is the primary treatment modality for Cushing's disease(CD). However, the predictors of post-operative remission and recurrence remain debatable. Thus, we studied the post-operative remission and long term recurrence rates, as well as their respective predictive factors. METHODS: Retrospective analysis of case records of 230 CDpatients who underwent primary microscopic TSS at our tertiary care referral center between 1987-2015was undertaken...

A 54-year-old woman was admitted to our hospital for detailed examination of acromegaly because she noticed bilateral hand and finger swelling at the age of 43 and plantar thickening, facial changes and unclear articulation at the age of 49. She had prominent brow ridges, mandibular protrusion, and enlargement of the hands, feet, nasal wings, lips and tongue. Her growth hormone (GH) level was 39.8 ng/ml, insulin-like growth factor-1 (IGF-1) level was 717 ng/ml, GH level was not suppressed (22.9 ng/ml) during a 75-g oral glucose tolerance test (OGTT)...

BACKGROUND: Preoperative radiologic evaluation of pituitary adenomas is essential. Despite the efforts made to determine the achieved resection grade after pituitary adenoma surgery, there is a high level of disagreement among all the available classifications and measurement methods employed. Our study aimed to determine pituitary adenoma imaging features, easily obtained from preoperative magnetic resonance, which could be used as resection predictor variables. Secondly, we analyzed the usefulness of the ellipsoid method in pituitary adenoma volume determination...

BACKGROUND: and Importance: In skull-base tumors involving the cavernous sinus (CS), indications for aggressive resection are sparse and must be carefully examined because of their invasiveness. With careful evaluation, techniques including internal carotid artery (ICA) sacrifice with or without extracranial-intracranial (EC-IC) bypass may still be an option in some cases. In addition, previous surgery with the sacrifice of potential donor vessels requires adjusting the revascularization strategy...

Cavernous sinus hemangiomas (CSH) are rare benign extra-axial vascular lesions. Both radiological and clinical aspects are important, for deciding a therapeutic modality, including medical treatment, radiation therapy or microsurgery. In the particular case of CSH, a radical removal of the tumor often cannot be achieved and is associated with a considerable risk for intraoperative uncontrollable bleeding. An alternative treatment modality is radiosurgery. Here we report the case of a 45-year-old patient, who presented with diplopia due to left abducens nerve palsy...

BACKGROUND: The anterior clinoid process shares a close relationship with the optic canal, the internal carotid artery, the superior orbital fissure and the cavernous sinus. These structures may be involved in diseases whose surgical exposure requires prior clinoid process resection. METHOD: Based on operative cases we describe the different steps of this surgical technique and illustrate our surgical procedure with a video. Dividing the orbito-temporal periosteal fold is a key-step in order to optimize the elevation of the periosteal dural layer at the level of the superior orbital fissure to expose the contours of the anterior clinoid process...

Objective  Cavernous sinus hemangiomas (CSHs) are benign lesions accounting for less than 2% of the cavernous sinus tumors. They provide a formidable surgical challenge because of their vascularity and their being surrounded by critical neurovascular structures. In this study, one of the largest in available literature, we analyze our experience in the management of these unusual tumors and review the available literature. Materials  This is a retrospective analysis of patients who were managed surgically (both microsurgical and Gamma knife radiosurgery [GKRS]) for CSH at our Institution from 2007 to 2015...

Merkel cell carcinoma (MCC) is an uncommon but highly malignant neuroendocrine tumor of the skin. MCC can metastasize, but involvement of the central nervous system is rare. Here, we report a case of rapidly progressing metastatic MCC to the clivus and bilateral cavernous sinus in an immunocompromised patient. This case is unique in that it is the first case report showing MCC metastasis to the clivus from a distant site. It also demonstrates that a MCC metastasis can masquerade with symptoms of Tolosa-Hunt syndrome...

OBJECTIVE Tumors with cavernous sinus (CS) invasion represent a neurosurgical challenge. Increasing application of the endoscopic endonasal approach (EEA) requires a thorough understanding of the CS anatomy from an endonasal perspective. In this study, the authors aimed to develop a surgical anatomy-based classification of the CS and establish its utility for preoperative surgical planning and intraoperative guidance in adenoma surgery. METHODS Twenty-five colored silicon-injected human head specimens were used for endonasal and transcranial dissections of the CS...

OBJECTIVE Surgery is generally the first-line therapy for acromegaly. For patients with residual or recurrent tumors, several treatment options exist, including repeat surgery, medical therapy, and radiation. Reoperation for recurrent acromegaly has been associated with poor results, with hormonal control usually achieved in fewer than 50% of cases. Extended endonasal endoscopic approaches (EEAs) may potentially improve the results of reoperation for acromegaly by providing increased visibility and maneuverability in parasellar areas...

Orbital exenteration is a destructive and disfiguring surgery and involves removal of the entire orbital contents, soft tissue and often lids as well. We report a case of an eight month old female, with malignant orbital teratoma who underwent lid sparing exenteration for the destructive, locally advanced disease. Three month post surgery she developed recurrence with intracranial extension as well as socket infection with pus discharge. Repeat surgery involved a multispeciality approach for removal of the tumor which was abutting the cavernous sinus posteriorly and ethmoid sinus medially, apart from filling the entire bony orbit...

The authors describe the surgical anatomy for the endoscopic endonasal approach (EEA) to the ventrolateral skull base. The ventrolateral skull base can be divided into two segments: the upper lateral and lower lateral skull base. The upper lateral skull base includes the cavernous sinus and the orbit, while the lower lateral skull base includes the petrous apex, Meckel's cave, parapharyngeal space, infratemporal fossa, etc. To gain access to the upper lateral skull base, a simple opening of the ethmoid sinus provides sufficient exposure of this area...
