Mr Declan Costello MA, MBBS, FRCS (ORL-HNS)

Consultant Ear, Nose & Throat Surgeon

Mr Declan Costello is a highly experienced consultant laryngologist with extensive expertise in treating all aspects of voice disorders and hoarseness – from vocal cord nodules and cysts to polyps, papilloma, vocal cord paralysis and spasmodic dysphonia.

As a singer himself, he has a particular interest in treating voice disorders in performers. He is also one of the leading exponents of local anaesthetic laryngeal procedures, which can be particularly beneficial for patients with vocal fold paralysis.

He regularly runs workshops for singers and performers on voice health and anatomy.


Mr Costello studied music at St John’s College, Cambridge, where he was a choral scholar under Christopher Robinson. He went on to study medicine at Imperial College and undertook his ENT specialist training in the Oxford region.

He was appointed as a consultant ENT surgeon (specialising in voice disorders) at the Queen Elizabeth Hospital in Birmingham in August 2010. In December 2018 his NHS practice moved to Wexham Park Hospital in Berkshire.

Mr Costello runs weekly private clinics in London and NHS clinics in Wexham Park.

Amongst his non-clinical duties, he is the editor of ENT & Audiology News magazine. He is also the chair of the Communications committee of the June/July 2019 CEORL-HNS congress in Brussels.

He continues to sing regularly with a number of different groups.
