External Auditory Canal Transillumination-Guided Middle Fossa Approaches: An Anatomical Feasibility Study.
Oper Neurosurg (Hagerstown)
January 2025
Department of Neurosurgery, Yeditepe University School of Medicine, İstanbul, Türkiye.
Background And Objectives: The middle fossa approaches are tremendously versatile for treating small vestibular schwannomas, selected petroclival meningiomas, midbasilar trunk aneurysms, and lesions of the petrous bone. Our aim was to localize the internal acoustic canal and safely drill the petrous apex with these approaches. This study demonstrates a new method to locate the internal acoustic canal during surgery in the middle fossa.

Article Synopsis
- * Researchers conducted a systematic review of 27 studies involving 545 patients, identifying five main combined approaches: Anterior petrosal, Supra-tentorial, Infratemporal fossa, Retrosigmoid, and Far-lateral suboccipital.
- * The study found that these approaches, especially the Anterior petrosal, are effective in treating conditions like meningiomas while showing strong surgical outcomes and low complication rates.
An aggressive Cushing's syndrome originating from a rare thymic neuroendocrine tumor, controlled successfully with fluconazole and octreotide therapy before surgery.

Department of Endocrinology, Akdeniz University Faculty of Medicine, Antalya, Turkey.
Article Synopsis
- - A 49-year-old woman experienced severe symptoms, including fatigue and resistant hypertension, leading to the diagnosis of ectopic Cushing's syndrome caused by an atypical neuroendocrine tumor found in the thymus.
- - Diagnostic tests confirmed excessive adrenocorticotropic hormone (ACTH) levels and indicated a tumor, which was surgically removed following successful medical management to lower cortisol levels.
- - Post-surgery, the patient entered clinical remission without tumor recurrence, demonstrating the importance of early detection and treatment of these rare and potentially life-threatening tumors.

Study Design: Single institution retrospective cohort study.
Methods: The clinical data of 29 patients with 30 ELSTs who underwent surgery were retrospectively reviewed.
Comparison of endoscopic multiport approaches to the petrous apex: contralateral transmaxillary versus contralateral medial transorbital corridor.
J Neurosurg
December 2024
Departments of2Neurological Surgery and.
Article Synopsis
- The study explores the challenges of accessing the petrous apex (PA) using endoscopic techniques, comparing two methods: the traditional endoscopic endonasal approach (EEA) combined with the contralateral transmaxillary (CTM) corridor and a proposed new method called the contralateral medial transorbital (cMTO) corridor.
- An anatomical analysis was conducted using 14 cadaveric specimens to dissect and assess each approach, focusing on metrics like working distance, angle of attack, and surgical freedom.
- Results indicated that the cMTO corridor offers a significantly shorter working distance to the PA compared to the CTM and EEA methods, with similar visual angles
