Treatment restrictions due to coronavirus (COVID-19)

As part of our longstanding relationship, we are proud to be dedicating our resources to the NHS at this important time. As a result many of our treatments are currently suspended and we are reviewing all planned procedures and consultations. We are making every effort to talk to impacted patients and apologise for any inconvenience this may cause.

Professional profile

My practice covers patients with general ear, nose and throat disorders with a special interest in nose or rhinological disorders. I am a Consultant Surgeon at the Queen Alexandra Hospital, Portsmouth and St Richards Hospital, Chichester. I graduated in 1995 from University of Calicut, India. I have extensive experience in ENT disorders having trained in India and UK. My surgical training in the UK was initially at West Midlands followed by advanced training in ENT in the Northern deanery. I have a doctoral degree in research, investigating chronic sinusitis from Newcastle University.

I am the current Clinical Director of the ENT Department, Queen Alexandra Hospital, Portsmouth. I regularly perform FESS (including advanced FESS), advanced septoplasty and rhinoplasty surgery, ear and throat surgery. I am one of the few surgeons in the UK who uses image navigation equipment for complex sinus surgery.
