TORS (Transoral Robotic Surgery) is an advanced, minimally invasive surgical technique that allows surgeons to remove tumors in the throat, tongue base, and tonsils through the mouth without any external incisions. Using the da Vinci robotic system, surgeons can access hard-to-reach areas with 3D high-definition vision and wristed instruments that provide greater precision than traditional surgery. Benefits include no visible scars, faster recovery (3-4 days hospital stay vs. weeks), preserved ability to speak and swallow, less pain, and lower risk of complications.

Dr. Vidhyadharan treats a comprehensive range of head and neck conditions including: oral cavity cancers (tongue, floor of mouth, gums), throat cancers (tonsil, pharynx, larynx), thyroid and parathyroid disorders, salivary gland tumors, neck masses and lumps, voice disorders and vocal cord lesions, swallowing disorders (dysphagia), obstructive sleep apnea, skull base tumors, and reconstructive procedures after cancer surgery. He specializes in both malignant (cancerous) and benign conditions affecting the head and neck region.

Dr. Vidhyadharan is recognized as a leading expert in dysphagia (swallowing disorders) with specialized training and leadership roles. He served as Clinical Lead Consultant of the Swallowing Disorders Centre at Amrita Institute (2015-2019) and currently serves as Lead Academic and Research Coordinator for the Foundation for Dysphagia Research and Education. He is the National Observer representing India for the Asian Dysphagia Society. His expertise is particularly valuable for cancer patients who often face swallowing difficulties after treatment, as he can provide both surgical and rehabilitative care.

Yes, Dr. Vidhyadharan is highly skilled in microvascular reconstructive surgery, having received specialized training at Chang Gung Memorial Hospital in Taiwan, one of the world's leading centers for reconstructive microsurgery. This expertise is crucial for patients undergoing extensive cancer surgery, as it allows him to reconstruct defects using tissue from other parts of the body (free flaps) with microsurgical techniques. This ensures both functional restoration (ability to eat, speak, breathe) and aesthetic outcomes after complex head and neck cancer surgeries.

While a referral from another doctor can be helpful in providing medical history and previous test results, it is not mandatory to see Dr. Vidhyadharan. Patients can directly book a consultation at THANC Hospital. However, bringing previous medical records, imaging studies (CT scans, MRIs), biopsy reports, and a list of current medications will help Dr. Vidhyadharan provide the most comprehensive evaluation during your first visit.

Robotic surgery offers several advantages over traditional open surgery: (1) No external incisions means no visible scars, (2) 3D high-definition magnified vision provides superior visualization, (3) Wristed instruments allow greater precision in tight spaces, (4) Less trauma to surrounding tissues results in faster healing, (5) Reduced pain and shorter hospital stays (3-4 days vs. 2-3 weeks), (6) Better preservation of speech, swallowing, and quality of life, (7) Lower risk of complications and infections, and (8) Ability to access tumors that would otherwise require jaw-splitting or major reconstruction.
