At the interface between the head and neck and the intracranial space sits the skull base — a complex bony plate perforated by the cranial nerves, internal carotid arteries, jugular veins, and optic nerves. Tumours arising at or extending to the skull base represent some of the most technically demanding cases in all of surgical oncology. They sit at the convergence of neurosurgery, head and neck surgery, and — in some cases — ophthalmology and maxillofacial surgery.
For patients searching for skull base cancer in Ahmedabad, access to a surgeon with specific training in skull base approaches — working within a multidisciplinary team that includes neurosurgery — is not optional. It is the prerequisite for safe, effective treatment. At his oncological surgery practice, Dr. Vishal Choksi brings the subspecialty head and neck surgical expertise that forms one pillar of skull base cancer management in Ahmedabad, and works as part of a cancer hospital in Ahmedabad infrastructure that includes the necessary neurosurgical and radiological support for these complex cases. Patients also benefit from the guidance of a dedicated oncologist in Ahmedabad team coordinating systemic and radiotherapy components of multimodal treatment.
What Is the Skull Base and Why Are Tumours Here So Difficult?
The skull base is the floor of the cranial cavity — divided anatomically into three fossae:
- Anterior cranial fossa — underlies the frontal lobes; bounded anteriorly by the frontal bone, posteriorly by the lesser wing of the sphenoid and chiasmatic groove
- Middle cranial fossa — underlies the temporal lobes; contains the sella turcica (housing the pituitary gland) and the cavernous sinus
- Posterior cranial fossa — the largest fossa; houses the brainstem and cerebellum
Through these fossae pass all twelve cranial nerves, the internal carotid arteries, the jugular veins, the optic chiasm, and the cavernous sinus — structures that control facial movement, vision, hearing, balance, swallowing, and voice.
Tumours in this region cannot be approached through standard operative techniques without risking catastrophic injury to these structures. Skull base surgery uses specialised approaches — endoscopic endonasal, transcranial, transmastoid, infratemporal, and craniofacial — each designed to access specific skull base compartments while protecting adjacent critical anatomy.
Types of Skull Base Tumours Managed in Ahmedabad
Sinonasal Malignancies Extending to the Skull Base
Squamous cell carcinoma, adenocarcinoma, olfactory neuroblastoma (esthesioneuroblastoma), and sinonasal undifferentiated carcinoma arising from the nasal cavity or paranasal sinuses may invade the anterior skull base — eroding the cribriform plate and entering the anterior cranial fossa.
Esthesioneuroblastoma (olfactory neuroblastoma): A tumour arising from the olfactory neuroepithelium at the cribriform plate. Presents with unilateral nasal obstruction, epistaxis, and — in advanced cases — anosmia (loss of smell) and intracranial extension. Surgical resection via craniofacial or endoscopic approach, followed by radiotherapy, provides good disease control for localised disease.
Adenoid cystic carcinoma: Arising from salivary gland tissue within the sinuses; notable for perineural spread — the tumour tracks along cranial nerve sheaths into the skull base and intracranially. Treatment requires wide resection with attention to nerve sheath involvement.
Tumours of the Clivus and Central Skull Base
- Chordoma — arising from notochordal remnants; most commonly in the clivus; slow-growing but locally destructive; surgery combined with high-dose radiotherapy (proton therapy where available)
- Chondrosarcoma — arising from cartilaginous components of the skull base; surgical resection with radiotherapy
- Pituitary adenoma — most are benign; some are locally invasive and extend beyond the sella; managed by neurosurgical-led teams
Temporal Bone and Jugular Foramen Tumours
- Glomus jugulare tumour — a paraganglioma (chemodectoma) at the jugular foramen; highly vascular; causes pulsatile tinnitus, progressive lower cranial nerve palsies affecting voice and swallowing
- Cholesteatoma with skull base erosion — in chronic otitis media, an acquired cholesteatoma can erode extensively into the skull base
- Temporal bone carcinoma — squamous cell carcinoma of the ear canal or middle ear; requires temporal bone resection
Infratemporal Fossa Tumours
The infratemporal fossa — deep to the ramus of the mandible — may be involved by direct extension from the skull base or by tumours arising within it. Access requires the infratemporal fossa approach — a major undertaking combining facial skin incision, zygomatic arch removal, and careful dissection around the internal carotid artery and cranial nerves V3, VII, IX, X, XI, and XII.
Diagnosing Skull Base Cancer in Ahmedabad
Imaging — The Foundation of Skull Base Assessment
MRI of the skull base with gadolinium: Essential for soft tissue detail — demonstrating dural involvement, intradural extension, cavernous sinus infiltration, and perineural tumour spread along cranial nerve sheaths. The absence of visible tumour on CT does not exclude skull base involvement; MRI is required.
CT of the skull base (bone windows): Assesses the pattern of bony erosion — critical for surgical planning. CT demonstrates cortical destruction, orbital wall erosion, and bony foraminal involvement.
MR angiography / CTA: Assesses the relationship between the tumour and the internal carotid artery — critical if carotid sacrifice may be necessary; balloon occlusion testing evaluates contralateral hemisphere tolerance.
PET-CT: For systemic staging — excluding distant metastasis before embarking on complex skull base surgery.
Biopsy
For endoscopically accessible lesions (anterior skull base, sinonasal tumours), endoscopic biopsy under local or general anaesthesia provides tissue diagnosis. For middle and posterior fossa lesions, CT-guided biopsy or surgical biopsy at the time of definitive resection is required.
Surgical Approaches for Skull Base Cancer Treatment in Ahmedabad
Endoscopic Endonasal Approach (EEA)
The revolution of the past two decades in skull base surgery. Using endoscopes passed through the nostrils with the patient under general anaesthesia, the anterior and central skull base can be accessed without external incision — dramatically reducing surgical morbidity while providing adequate tumour access for selected lesions.
Advantages: No facial incision; faster recovery; lower cerebrospinal fluid leak rates with modern reconstruction techniques; direct visualisation of the tumour without brain retraction.
Limitations: Not appropriate for laterally extending tumours, those with significant orbital involvement, or cases requiring vascular control. Tumour size and lateral extension determine endoscopic candidacy.
Craniofacial Resection
For anterior skull base tumours with combined sinonasal and intracranial components, the classical approach combines a bifrontal craniotomy (neurosurgical component) with transfacial exposure (head and neck surgical component) — allowing en bloc removal of the anterior skull base with the attached dura and brain if necessary.

Infratemporal Fossa Approach
For middle skull base and infratemporal fossa lesions — requires facial nerve monitoring, zygomatic arch osteotomy, and careful internal carotid artery dissection.

Non-Surgical Treatment for Skull Base Cancer
Not every skull base tumour requires — or is amenable to — surgical resection. Treatment principles:
- Unresectable or borderline-resectable tumours: Concurrent chemoradiotherapy may achieve disease control and facilitate delayed surgery in responders
- Radiosensitive histologies (nasopharyngeal carcinoma, lymphoma): Definitive chemoradiotherapy provides excellent local control without surgery
- Post-operative radiotherapy: Most malignant skull base tumours receive adjuvant radiotherapy after surgery, particularly with close margins or adverse pathological features
- Stereotactic radiosurgery (Gamma Knife, CyberKnife): For selected benign or slow-growing skull base tumours (meningioma, acoustic neuroma, chordoma) where surgical risk exceeds disease risk
Conclusion: Expert Skull Base Cancer Care in Ahmedabad
Skull base cancer in Ahmedabad requires a combination of subspecialty surgical training, advanced imaging interpretation, neurosurgical collaboration, and integrated multimodal treatment planning that only a dedicated cancer hospital in Ahmedabad with a fully equipped multidisciplinary team can provide. The oncologist in Ahmedabad managing your case must understand which approach — endoscopic, craniofacial, or combined — is optimal for your specific tumour, and coordinate surgery with radiotherapy and systemic therapy within a unified treatment plan.
At Dr. Vishal Choksi’s practice, this level of subspecialty skull base oncological expertise is available for patients across Gujarat.
