Summary: The endoscopic endonasal transtuberculum approach is effective for lesions involving the suprasellar and retrochiasmatic region, with preoperative planning and assessment being crucial. Attention to essential steps of the procedure and techniques to avoid complications are essential during surgery.

Summary: This case report describes an 18-year-old female presenting with progressive vision loss in the left eye. Imaging revealed a large mass in the sphenoid sinus, sella, and anterior cranial fossa, which was successfully resected through an endonasal endoscopic approach. Pathological diagnosis identified the tumor as the psammomatoid variant of juvenile active ossifying fibroma (JAOF).

Summary: This article discusses a rare case of ethmoidal dural arteriovenous fistula (dAVF) and its successful treatment using an endoscopic endonasal approach. The dAVF was successfully disconnected and skull base defect was repaired. The patient did not experience any postoperative complications such as cerebrospinal fluid leak and diabetes insipidus, and the dAVF was obliterated confirmed by postoperative angiogram.

Summary: Inverted papilloma is the most common benign sinonasal neoplasm that requires complete resection to prevent recurrence. The tumor should be completely removed along with normal bone and mucosa. They most commonly appear in the lateral nasal wall or maxillary sinus with a 5% to 15% chance of malignant transformation. Only 10% to 14% occur in the sphenoid sinus.

Summary: Medial acoustic tumors are a rare type of vestibular schwannoma with distinct clinical and radiological features. Surgical resection is challenging due to their size and hypervascularity, but hearing preservation should be sought as a goal.

Summary: Indications and limitations of the anterior transpetrosal approach include accessing the Meckel cave and upper petroclival region. Preoperative planning is essential to visualize the boundaries of the posteromedial triangle of the middle fossa. The procedure involves a supine position, temporal craniotomy, stripping of the dura, coagulating and cutting the middle meningeal artery, releasing the greater superficial petrosal nerve, and performing case-specific anterior petrosectomy.

Summary: Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular benign tumor that often originates in the sphenopalatine foramen and can spread to adjacent compartments. Microsurgical resection with preoperative embolization remains the treatment of choice. This case report presents a successful gross total resection of a large JNA involving multiple compartments.

Summary: This study compared the effectiveness of the Fisch type A approach and the extreme medial approach for treating jugular foramen diseases. The results showed that the extreme medial approach had comparable surgical maneuverability to the Fisch type A approach and provided better surgical field visualization while preserving the jugular bulb. Therefore, the extreme medial approach should be considered in certain specific cases.

Summary: Orbital cavernous hemangiomas are well encapsulated vascular lesions that can be surgically removed without infiltrating surrounding tissues. They are the third most common intraorbital lesions in adults, following lymphoid tumors and idiopathic orbital inflammation. The spread pattern of contrast enhancement on dynamic CT or MRI can help diagnose OCHs. In this case, an elderly lady presented with protrusion of the right eye and increased tearing, and imaging revealed an intraconal lesion. An endonasal transethmoidal approach was used to treat the lesion, and the patient had a successful recovery with complete resolution of proptosis.
