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.
FAQs
An added margin can help address tissue immediately surrounding the lesion while supporting the goal of complete removal. The extent of excision must be balanced against preservation of nearby healthy structures. This balance is especially relevant when resection is intended to manage a localized tumor or another focal abnormality without creating unnecessary tissue damage.
Planning determines how clinicians localize the lesion and select an access route that reaches it while protecting nearby healthy structures. The planned route also supports controlled excision and bleeding management. These decisions connect the lesion’s position with the practical goals of surgery, including effective removal and preservation of surrounding tissue.
Bleeding control is a central operative consideration because excision disrupts tissue as the lesion is removed. Clinicians incorporate bleeding management into the surgical process while working to preserve nearby healthy structures. Maintaining this balance supports completion of the resection and helps protect the operative area during treatment of a focal abnormality.
Pathology examines the removed specimen for cellular features and assesses whether the lesion appears to have been completely removed. Those findings can establish a definitive diagnosis and clarify the result of surgery. The interpretation may then guide decisions about further treatment or ongoing surveillance, depending on the lesion’s characteristics and removal status.
Lesion resection is particularly relevant when disease is concentrated in a defined area that clinicians can localize and access surgically. In this setting, removal may serve both management and diagnostic purposes. The resulting specimen provides information for pathology, while the surgical outcome can support subsequent treatment planning, surveillance, or rehabilitation.
Postoperative findings can influence several next steps rather than ending care at excision. Pathology may clarify the lesion’s cellular features and whether removal was complete, helping clinicians determine whether additional treatment or surveillance is appropriate. Depending on the patient’s needs and the procedure’s effects, rehabilitation may also become part of ongoing management.
