Who this is for
This service is for patients and families outside India who want an expert review of an existing diagnosis before making treatment decisions. You keep your local treating team — Dr. Vidhyadharan provides an independent opinion to discuss with them.
- You or a loved one has been diagnosed with a head & neck cancer and want to understand all treatment options before committing to a plan
- You have a thyroid nodule, parotid mass or neck lump and want an expert look at your scans and biopsy
- You are dealing with a voice problem, hoarseness or laryngeal lesion and want a laryngologist's opinion
- You or your child has a swallowing difficulty that has been hard to diagnose or treat locally
- You want to know whether treatment at an expert centre in India (such as THANC) would be a reasonable option for you
- You are an Indian-origin family and prefer a second opinion in English, Tamil or Hindi
About this consultation
This is an educational second-opinion consultation. Dr. Vidhyadharan does not prescribe medication or direct treatment in your country of residence. The opinion is intended for you to discuss with your local treating doctor, who remains responsible for your ongoing care. This service complies with India's National Medical Commission (NMC) Telemedicine Practice Guidelines 2020, which expressly permit second-opinion teleconsultations to patients outside India.

Conditions we review most often
Dr. Vidhyadharan focuses on four areas where a second opinion most often changes the treatment path. Each page explains exactly what we review for that condition and what you'll get back.
Head & Neck Cancer
Reviewing your biopsy, imaging and staging to give you a clear, unhurried second opinion on surgical, radiation and systemic treatment options.
Voice & Vocal Cord Disorders
For patients with vocal cord lesions, voice loss, laryngeal cancer or voice changes after treatment — a careful review of stroboscopy, imaging and pathology by a fellowship-trained laryngologist.
Thyroid & Parotid Tumors
For patients with a thyroid nodule, papillary or medullary thyroid cancer, parotid mass or salivary gland tumor — a second look at your FNAC, ultrasound and scans to confirm next steps.
Swallowing & Dysphagia
For patients and parents worried about swallowing difficulty, aspiration, feeding problems after cancer treatment, or unexplained weight loss — a focused review of your FEES, videofluoroscopy and imaging.
What international patients say
Both quotes below are already published on our testimonials page. They are shared here verbatim.
“Dr. Vidhyadharan offered detailed counselling and guidance over a video teleconference for my son Varun's dysphagia (swallowing) issue, with a demonstration through a model that gave excellent clarity. It provided a lot of confidence to us and helped us discuss the case with our doctor in the USA.”
“I live in California and have suffered from chronic cold symptoms for many years. Dr. Vidhyadharan performed a thorough evaluation including a camera-assisted nasal examination, and his explanations were exceptionally clear. He recommended simple nasal rinses with an inhalable spray for a short duration, and this treatment has made a significant improvement in my quality of life. A warm, humble and approachable physician.”
