Lateral Molar Approach-Driven Transoral Endoscopic Procedure for Benign Infratemporal Fossa Tumor Resection
0 Views •
2025
Here, we present a protocol to resect benign infratemporal fossa tumors via an endoscopic-assisted transoral lateral molar approach with low-temperature plasma ablation and intraoperative mandibular nerve monitoring. This minimally invasive technique prioritizes anatomical preservation, functional recovery, and avoidance of external scarring, demonstrating feasibility for well-demarcated lesions ≤4 cm in diameter.

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.

Source: Alomari, S., et al. Implementation of Minimally Invasive Brain Tumor Resection in Rodents for High Viability Tissue Collection. J. Vis. Exp. (2022)This video demonstrates the use of a minimally invasive resection system (MIRS) to excise tumor tissue from an anesthetized mouse implanted with a tumor. The procedure involves securing the mouse onto a stereotactic frame, reopening the previous surgical site to access the brain, and inserting a specialized cannula that utilizes suction and a...
FAQs
Submucosal injection helps lift the lesion away from deeper tissue before cutting. This creates separation between the target and surrounding layers, making the abnormal area more distinct through the endoscope and supporting removal with a snare or other cutting device. The lifting step is therefore especially relevant when the lesion’s position or depth affects how it can be approached.
The two approaches are selected according to features such as lesion size and depth. Endoscopic mucosal resection removes suitable tissue using a mucosal resection approach, whereas endoscopic submucosal dissection is used when a different depth of separation and excision is needed. This distinction allows the technique to be matched to the characteristics of the localized abnormality.
Suitability depends primarily on the lesion’s location within the lining, its size, and how deeply it extends. These features influence whether lifting, snare removal, or a more extensive dissection approach is appropriate. Because the method is intended for selected lesions, assessment of these characteristics helps determine whether endoscopic treatment can remove the abnormality without open surgery.
The endoscope first provides direct visualization of the abnormal area. Instruments passed through its channels then support submucosal injection when lifting is needed, followed by separation and excision with a snare or cutting device. The removed tissue is collected for histopathological assessment, linking the technical removal step with later evaluation of the lesion’s characteristics.
Clinicians may use this approach for selected cancers, precancerous growths, and other localized abnormalities affecting the lining of hollow organs, particularly in the gastrointestinal tract. Its value is greatest when the lesion can be approached through an endoscope and removed without open surgery. The method therefore combines local treatment with tissue collection for diagnostic assessment.
Resected tissue enables histopathological assessment, meaning examination of the specimen to characterize the abnormal lesion. This provides information beyond what is visible during endoscopy and helps evaluate the removed tissue in a medical context. The specimen therefore serves both as evidence that tissue was excised and as material for assessing the lesion after removal.
