2026
This study describes a standardized surgical procedure for single-port endoscopic axillary lymph node dissection without liposuction in breast cancer. Indicated for patients with biopsy-confirmed nodal metastasis or positive sentinel lymph nodes, the technique emphasizes preservation of critical structures, particularly the intercostobrachial nerve, to reduce postoperative morbidity and optimize functional recovery.

Full-Endoscopic Surgery for Hypothalamic Hamartoma Resection

2024
Hypothalamic hamartomas are rare, non-neoplastic congenital malformations mainly arising from the inferior hypothalamus or tuber cinereum. Surgical treatment is one of the most effective options, and the surgical approach must be precisely determined for each patient. Here, we describe the full-endoscopic technique for resecting hypothalamic hamartomas.
FAQs
Angled visualization allows surgeons to inspect areas that may not align directly with the nasal corridor. A small endoscope provides views through the nasal cavity and sphenoid sinus, while specialized instruments work along the same route. This combination can improve access to anatomically difficult skull-base regions, including the pituitary area and anterior skull base.
These spaces create a direct anatomical route toward selected structures at the skull base. Using them can reduce the need to create external access points and may limit extensive brain retraction. Their importance is therefore both anatomical and procedural: they connect the surgeon’s working instruments with targets such as pituitary tumors and certain skull-base lesions.
The approach reaches selected skull-base targets through existing nasal and sinus pathways rather than through an external incision. That distinction can reduce the amount of tissue disruption associated with access and avoid extensive brain retraction. However, its usefulness depends on whether the lesion or defect can be reached through this anatomical route.
These supporting technologies and techniques address different parts of the operation. Imaging helps characterize the relevant anatomy, navigation supports orientation during the approach, and reconstruction focuses on restoring or securing the operated region. Together with postoperative care, they extend the method beyond visualization and instrument placement to include planning, closure, and recovery.
In neurosurgical practice, applications include pituitary tumors, selected skull-base lesions, and cerebrospinal fluid leaks. The method is not presented as suitable for every lesion; selection depends on whether the target or defect can be accessed through the nasal and sphenoid sinus pathway. Its direct access has broadened options for managing these conditions.
The technique links detailed skull-base anatomy with the management of structures that affect neurological and endocrine function, particularly the pituitary region. Its development has encouraged research on visualization, image-guided navigation, reconstruction, and postoperative care. These areas help neuroscience and neurosurgery evaluate how anatomical access can be improved while limiting tissue disruption.
