Dr Scoppa gave oral evidence which did not add materially to his written report. Dr Paul Fagan, who specialised in neuro-otology, reported that severe outer ear infection, particularly with a fungus, can cause a tympanic membrane perforation.
12 In his evidence, Dr Cross explained the manner in which he had syringed the left ear and the technique he had used. His technique as so described accorded with a technique which Dr Scoppa said was the best practice. Dr Cross said that he was experienced in the procedure and, in a peak season, would perform it about ten times a day and, in an off season, three to six times a day. In cross-examination, it was not specifically put to Dr Cross that he had adopted an inappropriate procedure, that he had used an inappropriate pressure of water or that his syringing had been inappropriately energetic. Indeed, he agreed with counsel for Mr Towns that, in hindsight, he would not have acted differently.
13 Much of the cross-examination went to another point, namely, that Mr Towns had made his view clear to Dr Cross that he wished to see a specialist and that he wished Dr Cross to arrange an urgent appointment, which Dr Cross refused to do. That issue is not involved in the appeal. It was not suggested at the trial or in the appeal that the general nature of Dr Cross's treatment was inappropriate pending consultation with a specialist.
14 On the issue of negligence in syringing, the trial Judge found for Dr Cross. The trial Judge, inter alia, said:-
"Like Dr Scoppa, on the evidence before me, I an [sic] unable to say that the defendant carried out the syringing procedure, or indeed the placing of a wick in the ear, in a careless way, or that he should not have syringed the ear. It seems that that was the acceptable treatment, and so it seems that what happened unfortunately was that the doctor syringed the ear quite competently but, during the course of syringing, probably because of the weakened state of the ear, the perforation occurred. I cannot see that there is any negligence which causes the perforation."
15 In the appeal, this finding was the subject of some brief written submissions by counsel for Mr Towns, which were not the subject of further elaboration in the oral submissions. The written submissions relied upon this evidence of Dr Hulcome:-
"Q. Whether or not the syringing caused the perforation depends upon the technique that was used?
A. Usually.
Q. Well, when you say 'usually' it's not usual to cause a perforation simply by syringing an ear?
A. I've seen two in the last two years, but usually those drums have been weak already and the syringing has been fairly energetic but yet it can occur in every day practice.
Q. But if the syringing technique is appropriate then it ought not to perforate an eardrum?
A. It will not perforate a normal eardrum but if an eardrum is very thin or weakened then it can perforate."
16 It was submitted that the use by Dr Hulcome of the words "fairly energetic" carried the meaning that there would be an excessive use of force associated with the perforation of an ear in the course of syringing. I do not draw that inference from Dr Hulcome's evidence. Nor do I draw any adverse inference from another passage which was relied upon in the submissions and which appeared in the oral evidence of Dr Scoppa. The finding by the trial Judge, that the evidence did not show that there had been negligence on the part of Dr Cross in the syringing of Mr Towns' left ear, was well based.
17 The main issue raised in the appeal turns upon Dr Cross's failure to warn Mr Towns of the possibility that problems might arise if the ear were syringed. Dr Cross conceded that he gave no such warning. In his written report, Dr Scoppa said, inter alia:-
" 3. What are the known risks associated with the treatment undertaken by Dr Cross?
…
I enclose a photocopy of pages 242 to 245 of Mawson' & Ludman's Textbook of 'Diseases of the Ear' … where the technique, precautions, and complications of ear syringing are discussed. Mawson mentions the following complications:
1. Reactivation of inactive or quiescent otitis media.
2. Rupture of the tympanic membrane. This is also reported by Brahe Pedersen & Vendelbo Johansen …
3. Caloric stimulation of the labyrinth. This is also reported by Reker & Rudert …
4. Scalding the meatus.
Other complications of syringing that have been reported include:
5. Otitis externa reported by Dingle …
6. Cessation of the heartbeat reported by Prasad …
7. Malignant otitis externa reported by Ford & Courtney-Harris …
4. What is the incidence of injury from the treatment?
Sharp et al … reported that 38% of 105 practitioners had experienced complications after performing ear syringing, and estimated that severe complications requiring specialist referral occur in approximately 1 in 1000 cases.
5. What appropriate advice and/or warnings ought to have been given to the patient prior to undertaking the treatment?
In my opinion a patient who is to undergo syringing and/or insertion of a wick should be advised that the procedure can be painful, and that trauma to the eardrum and/or ear canal skin may result, and that temporary dizziness may ensue if the irrigating fluid is too warm or too cold."
18 I must note that I would find it surprising if the warning which Dr Scoppa recommended was, in practice, a warning commonly given by practitioners. Why would a practitioner advise his patient that dizziness might ensue if the irrigating fluid was too warm or too cold? One would assume that it was the practitioner's task to have the fluid at the correct temperature. However, Dr Scoppa was not asked whether the warning he recommended was either one which he himself gave to patients or one which was commonly given by practitioners.
19 The trial Judge rejected the claim on two bases, one being that he considered that the risk involved in syringing the ear was too minimal a risk to warrant warning a patient about it and the other that he was not satisfied on the balance of probabilities that Mr Towns would have refused the treatment had he been given a proper warning.
20 It is unnecessary and inappropriate to discuss the first ground upon which the trial Judge refused the claim. Warning cases should be conducted with great care and with attention to detail. That is because they are cases in which, very often, the issues are difficult and the court may be asked to lay down a standard of behaviour for medical practitioners which does not accord with the general practice of persons skilled in the profession. In the present case, very little was said on the issue of warnings. It may be inferred that Dr Paton did not give a warning. Dr Cross said that he did not give a warning, but gave no further evidence on the topic. Dr Hulcome was asked no questions about and gave no evidence about a warning. Dr Scoppa gave evidence in his written report, which I have set out above, but was asked no questions about it in his oral evidence. Dr Fagan, who reported to the solicitors for Dr Cross, made no mention of the issue.
21 Mr Towns did not, before the evidence for the plaintiff and the defendant was closed and counsel had addressed, give any evidence as to what would have occurred had he been given a warning, such as that propounded by Dr Scoppa. In a warning case, evidence as to what the plaintiff would have done, had a warning been given, is necessary to establish that damage flowed from the lack thereof. In Ellis v Wallsend District Hospital (1989) 17 NSWLR 553, Kirby P, at p 559, expressed the causation issue in the following way:-
"… I consider that the question to be asked is whether, in the particular circumstances, the risk was such that the particular patient should have been told and, if told, would not have accepted the treatment."
