Notable Cases Handled
Dr. Abhaya Kumar managed a complex case of an 87-year-old woman suffering from Trigeminal Neuralgia for 10 years. Due to her advanced age, open surgery was high-risk. Dr. Kumar performed a Percutaneous Balloon Compression, a day-care procedure under mild sedation. The patient experienced immediate pain relief with a 90% success probability, avoiding the risks of major surgery.

Patient Testimonials

"I had been suffering from severe back pain for 8 years. Dr. Abhaya Kumar diagnosed a rare tumour on my spine. He performed a thoracotomy and removed the tumour completely. I was discharged in 10 days with zero deficits. He is undoubtedly the best neurosurgeon in Mumbai."  – Helen D.

"My father had Parkinson's and was struggling with tremors. Dr. Kumar performed Deep Brain Stimulation (DBS). It was like a miracle; his quality of life has improved drastically. The doctor's disciplined approach is commendable." – R. Mehta

"I was terrified of brain surgery, but Dr. Abhaya Kumar suggested an 'Awake Craniotomy'. He spoke to me during the surgery, ensuring my speech was not affected. His skill and the technology at the hospital are world-class." – S. Iyer

Patient-Centred Care
Dr. Abhaya Kumar’s mantra is "Disciplined practice." He believes in listening carefully to patients and their relatives, maintaining transparency through good communication, and giving 100% effort to every case. He strives to balance hard work with family time, believing that the happiness of his family reflects in his care for patients.

Technology & Innovation
Dr. Kumar is a proponent of using advanced technology to minimise surgical trauma. He regularly utilises Intraoperative MRI (IMRIS), Neuronavigation, Stereotaxy, and the O-arm for spinal precision. His unit is one of the few in India to offer the full range of Minimally Invasive Spine Surgeries using tubular retractors and endoscopy.
