Tumours removed through transcranial microscopic surgery

Tumours removed through transcranial microscopic surgery Published – August 21, 2026 05: 57 pm IST – THANJAVUR.

Key points

• After tumour removal, the neurosurgical team reconstructed the anterior cranial fossa, the front portion of the skull base separating the brain from the nasal and sinus cavities.
• The rare and aggressive tumours in all three patients arose in the region where the nasal cavity and the base of the skull meet.
• The ENT team accessed the tumour endoscopically through the nose.

Notably, a Neurosurgical team at Meenakshi Hospital, Thanjavur, has removed tumours extended from nasal cavity and paranasal sinuses to the skull base in three patients by adopting a complex procedure of a combination of advanced endoscopic techniques and transcranial microscopic surgery.

According to the hospital release, in all three cases, the team with assistance from an ENT team, applied a microscopic approach through the skull to remove the tumour involving the skull base and intracranial region. The ENT team accessed the tumour endoscopically through the nose.

After tumour removal, the neurosurgical team reconstructed the anterior cranial fossa, the front portion of the skull base separating the brain from the nasal and sinus cavities. This reconstruction was crucial to protect the brain and prevent cerebrospinal fluid (CSF) leakage. It can growth the risk of serious infections such as meningitis.

Notably, the rare and aggressive tumours in all three patients arose in the region where the nasal cavity and the base of the skull meet. These surgeries, each lasting 10 to 15 hours, were performed by N. Arunkumar, Senior Consultant – Neurosurgery, V.Sri Priyadharsan, Associate Consultant – Neurosurgery, and Isaac Richards, Senior Consultant – ENT, with anaesthesia backing from G. Arimanickam, Senior Consultant – Anesthesiology. Notably, the surgeries additionally utilised CUSA, an advanced ultrasonic surgical device that helps surgeons remove tumour tissue precisely while controlling bleeding and maintaining clear visibility of the surrounding tissues, the release went on.

In short, tumours removed through transcranial microscopic surgery is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
