Analysing clinical negligence claims against MDU member ear, nose and throat surgeons, and advice on managing risk in this speciality.

There are many factors that can affect the likelihood of a claim being brought against a doctor, including the extent of their private practice and their individual case mix. But broadly speaking, an ENT consultant working privately can anticipate being on the receiving end of a claim about once every 10 years.

In addition, the MDU assists its ENT members with other medico-legal matters including GMC complaints, inquests, disciplinary procedures and even criminal enquiries. This article, however, focuses on an analysis of a cohort of over 100 clinical negligence claims recently brought against ear, nose and throat (ENT) surgical members working in independent practice.

Compensation costs

In 75% of claims reviewed, the claim was successfully defended without any payment of damages or claimant legal costs. Of the 25% cases that were settled, compensation payments ranged from £100 to £2.5 million. Total case costs (including damages, claimant costs and defence costs) averaged over £50,000 per settled case.

The wide variation in damages paid when a claim is settled reflects the variety of different types of case ENT surgeons can be involved in and the wide range of complications that can occur.

Compensation payments aim to return the patient to the position they would have been if the negligence had not occurred. The size of the compensation paid does not reflect the magnitude of the clinical error, but rather the injury to the patient. If the person can no longer work and requires a significant level of care, then considerable damages may be paid.

In this analysis, the highest awards were for neurological injury following surgery. One claimant was paid £2.5 million in compensation following an iatrogenic brain injury during revision (functional endoscopic sinus surgery) and sustained resultant long-term neurological impairment.

Three of the five highest payments involved complications of endoscopic sinus surgery. On the other end of the spectrum, the three lowest payments were to patients who sustained damaged teeth during surgery or laryngoscopy.

While claims numbers have remained steady in recent years, the cost of claims has spiralled. This is not due to clinical standards but to a deteriorating legal environment which the MDU is campaigning to reform. You can find out more at

Legal costs

When a claim is settled, the MDU also pays the claimant’s legal costs. Such costs can be considerable and can be equal to or exceed the compensation paid to the claimant. The highest costs paid by the MDU on a single claim were for nearly £400,000.

Even in claims that are successfully defended, the MDU can incur significant expenditure, particularly if there are court proceedings. These costs include obtaining expert advice - which for complex claims can involve multiple specialists - and legal expenditure.

The MDU always investigates claims thoroughly, in order to advise and assist members most effectively. Overall, nearly half of claims (46%) were resolved by the MDU claims handler without the need to instruct a solicitor.

Total case costs (including damages, claimant costs and defence costs) averaged over £50,000 per settled case.

Outcome of cases

Claims that were not settled were either won, discontinued by the claimant or statute barred - whereby the claimant fails to bring a claim within three years from the date of the incident or the date of their knowledge of the alleged harm.

This restriction does not apply to children with capacity, for whom the limitation period begins at 18 (16 in Scotland). There is no time limit for patients who lack capacity to conduct their own affairs. Some claims were initially investigated by the MDU but successfully argued to not involve an MDU member.

Outcome of the claims in the analysis:

Closed/discontinued - 54%

Settled - 25%

Statue barred - 18%

Won at trial/struck out - 3%

Reasons for claims

The reasons for ENT claims range from post-operative pain or scarring to severe complications resulting in significant further treatment, trauma and in some cases, the patient's death. There are some key overriding themes of ENT claims, as explained below.

Dissatisfaction with outcome

ENT procedures performed for cosmetic reasons such as septoplasties and rhinoplasties can result in claims of dissatisfaction with the final aesthetic result. Numerous claims arose from patients alleging a lack of improvement or worsening of their symptoms, such as breathing difficulties, snoring, sleep apnoea and sensory loss affecting taste, smell and hearing.

These claims will usually involve the cost of refunds, second opinions, revision surgeries and psychological therapy.


A third of the cases alleged inadequate consent, with a focus on failure to discuss risks of complications and failure to warn that symptoms may not be improved.

In order to manage a patient's expectations of a procedure, including balancing the potential risks and benefits, a thorough consent process is paramount. Claims can be defended where a thorough and detailed discussion with the patient takes place and is well-recorded in the notes.

Other cases alleged that the treatment provided was unnecessary or incorrect in the circumstances, or that more conservative treatment options (including medication or no treatment) should have been tried or reviewed with the patient.

In one case it was alleged that non-surgical treatment and a CT scan should have been performed before sinus surgery. Unfortunately the patient died from hyponatremia-induced cardiac arrest after being discharged from hospital. This claim was settled for around £250,000 in compensation and claimant's legal costs.

Intra-operative complications

Problems that arose during a procedure included:

  • diathermy burns causing scarring or nerve damage
  • dental damage or loss of teeth
  • perforations such as of the septum or oesophagus
  • nerve damage and bone damage such as cracking of the orbital plate
  • severe bleeding and stroke.
Post-operative complications

Post-operative complications occurred in 40% of cases. Some were known complications such as pain, nausea, dizziness, scarring, poor healing, infections and mild to major sensory loss.

Neurological damage was seen in several cases. Examples included:

  • nerve damage causing muscle paralysis and reduced arm function following excision of a neck lesion
  • swallowing and speech difficulties after the laryngeal nerve was damaged during a thyroidectomy
  • subarachnoid haemorrhage following revision sinus surgery
  • stroke after a septoplasty
  • brain infections or meningitis necessitating further procedures and a poor outcome for the patient.

In one case following mastoidectomy and myringoplasty, the patient developed sepsis and multi-organ failure secondary to a post-operative infection, although made a good recovery. The case was settled for around £325,000 in compensation and claimant's legal costs.

Delayed diagnosis or referral

Allegations of delayed diagnoses or referral were also common. The diagnoses allegedly missed or delayed included:

  • brain tumours
  • cholesteatomas
  • sensorineural hearing loss
  • meningitis
  • labyrinthitis
  • post-operative infections or haematomas
  • cleft palate
  • mucocele
  • cancers of the tonsil, skin, nasopharynx, oropharynx and larynx.

In one case, in which a patient died, a delayed diagnosis of malignant otitis externa led to the patient developing bacterial meningitis and invasive laryngeal candidosis. In another case a patient having sinus surgery was found to have a congenital skull defect, which was mistaken for a mucocele. This led to complications and the need for the patient to have further operations.

Managing risks

Claims involving ENT surgeons are made for a wide variety of reasons, but there are some common risk factors which, if managed appropriately, can help to reduce risks.

  • Manage the patient's expectations as best as possible in terms of what can realistically be achieved. A thorough consent process is crucial in all ENT procedures, but especially for cosmetic procedures or if the treatment risks may outweigh the potential benefits.
  • Provide patients with detailed information on all treatment options verbally and in writing and make sure they have appropriate time to make a decision.
  • Keep detailed records of your discussions with patients, including any phone calls by you or your administrative team, and discussions between you and other clinicians such as GPs, out-of-hours clinicians and other consultants involved. Be aware that many claims are brought a considerable time after events in question.
  • Consider more conservative treatment options, and whether all avenues have been exhausted, before considering invasive procedures.
  • Give appropriate safety netting advice so the patient knows in what circumstances to return for further advice.
  • See the patient as a whole, not just the isolated issue at hand. This includes considering comorbidities and psychological factors.
  • Consider your professional duty of candour. If something goes wrong, apologise and notify the patient and any necessary parties as soon as possible.

A claim for clinical negligence can be brought at any time, often without warning and sometimes many years after the incident occurred. It can be very distressing to find out a patient is bringing a claim against you.

Our expert claims handlers and medico-legal advisers understand how stressful facing a claim can be, as well as the importance of mounting a robust defence of your position.
