Breakthrough in Neurosurgery: Seville Hospital Uses Minimally Invasive Technique to Remove Brain Tumors

The Hospital Universitario Virgen del Rocío in Sevilla has pioneered a groundbreaking neurosurgical technique to remove brain tumors located at the base of the skull. This minimally invasive approach, known as transorbital endoscopic surgery, allows neurosurgeons to access deep-seated tumors through the eye socket, eliminating the need for traditional craniotomy and significantly reducing patient recovery time.

How the Procedure Works

The technique involves creating a precise anatomical corridor between the lateral wall of the orbit and the eyeball, enabling surgeons to reach the base of the skull without opening the cranium. This method, described as “practically invisible,” minimizes tissue damage and cerebral manipulation. According to Dr. Eugenio Cárdenas, a neurosurgeon at the hospital, “This endoscopic approach avoids visible incisions and allows access to deep lesions with less harm to surrounding tissues and, most importantly, less cerebral manipulation.”

The procedure is performed in collaboration with the Ophthalmology department, with Dr. Aurora del Estad playing a key role in ensuring the safety and precision of the intervention. The hospital has already treated four patients using this technique since its implementation last year, with positive outcomes reported.

Benefits for Patients

One of the most significant advantages of this technique is the rapid postoperative recovery. Patients often leave the hospital within days, as highlighted by Dr. Juan Carlos García, who noted, “Patients go home sooner and with excellent aesthetic results.” A patient, Margarita, shared her experience: “I had a great postoperative recovery, no fever… I was discharged four days after the operation.”

The method also reduces the risk of complications associated with traditional craniotomies, such as brain retraction, and offers a less aggressive alternative for selected cases. While it does not replace all existing techniques, it expands the options available to neurosurgeons, particularly for tumors that are difficult to access via nasal or conventional skull approaches.

Future Implications and Research

The hospital plans to further develop the technique, aiming to treat more complex tumors in the future. The procedure is part of a doctoral thesis conducted in collaboration with the Department of Anatomy at the University of Sevilla, under the supervision of Dr. Jesús Ambrosiani. This research underscores the hospital’s commitment to advancing neurosurgical innovation.

As neurosurgery continues to evolve, the focus is shifting toward personalized, less invasive treatments that prioritize patient recovery and quality of life. The Virgen del Rocío’s adoption of this technique positions it as a leader in Andalusian neurosurgery, demonstrating how innovation can reduce surgical trauma while improving outcomes.

Key Takeaways

• The Hospital Universitario Virgen del Rocío in Sevilla has introduced a minimally invasive transorbital endoscopic technique to remove brain tumors.
• The method avoids craniotomy, reduces recovery time, and improves aesthetic results for patients.
• Collaboration between neurosurgery and ophthalmology is critical to the procedure’s success.
• The technique complements existing methods like endonasal surgery and is part of ongoing research to treat more complex cases.

This advancement reflects a broader trend in modern medicine toward precision and patient-centered care, proving that innovation in surgery is not just about reaching further but doing so with less harm.
