The Journal of Laryngology and Otology May 1986. Vol. 100. pp. 595-597 Clinical Records Nominal aphasia following a radical mastoidectomy by B. A. GIRGIS and J. SIEGLER (Wirral) Introduction This case is being reported because it is a rare complication to a routine radical mastoid operation. Its purpose is to advise otologists of such a possibility and guide them in management and prognosis should they come across such a complication. Intra-cranial complications of chronic otitis media are well documented in the standard text books of otology. Intra-cranial complications following a radical mastoid operation are rare, bearing in mind the large number of mastoid operations which are still being performed by otologists practising in heavy industrialized areas with large populations who are living under adverse hygienic conditions. The recent increase of litigation alleging negligence during operations is an additional reason for bringing this unusual complication to the notice of otologists. There have been only two previous case reports on this complication (Windle-Taylor, 1980). History P.M., aged 13, was seen in the outpatients department at Arrowe Park Hospital on 12 November 1983 complaining of pain in his left ear. It had begun three months previously and had recurred twice during this period. There had been a history of the patient inserting a foreign body into his left ear during childhood. His left ear showed an attic perforation through which cholesteatoma was being discharged. The right ear showed a normal drum and canal. His audiogram showed a conductive loss in both ears but was more severe on the left. The initial treatment was a course of aural toilet in the outpatients but the ear continued to discharge. In December 1983 his left ear was examined under anaesthetic and an attempt was made to evacuate all the cholesteatoma through the attic perforation. The disease was found to be inaccessible and a mastoid operation was therefore advised. The mastoidectomy was performed on 16 May 1984 via an incision behind the ear. The mastoid was found to be partially pneumatised and the cells contained infected mucous membrane and granulation tissue. The middle ear was opened and cholesteatoma was found to occupy the attic and mesotympanum. The incus showed necrosis of its long process. During the operation the dura of the middle cranial fossa was exposed and recorded as being healthy. There was a small area of bleeding which was treated by the use of a diamond burr and diathermy. The diseased air cells and cholesteatoma were removed together with the remains of the incus and the head of the malleus. A BIPP pack was inserted into the cavity as a routine procedure. Post-operatively the patient was well until the third day after operation when he complained of a severe headache. Next day he behaved in a very strange manner and he was found to be suffering with nominal aphasia. An attempt was made to get him to name various common objects but he was unable to do so. The patient was then referred to the Regional Neurological Centre where he was examined by Mr. John Miles, consultant neurosurgeon. A CAT scan was performed but there was no evidence of a brain abscess or a shift of the mid-line structures to one side. The region of the left temporo-parietal region of the brain showed evidence of low density (Fig. 1), which was consistent of a diagnosis of 595 B. A. GIRGIS AND J. SIEGLER FIG. 1.

During his investigation in the Regional Neurological Centre he had one fit of Jacksonian epilepsy which lasted for two minutes. It was treated by Erythromycin 250 mgs. four times a day, Epilim 200 mgs. three times a day, and he was referred to a speech therapist in Arrowe Park. His aphasia lasted for about a week and he then responded to speech therapy. During the initial phase of his illness he failed to respond to all forms of testing. He was unable to understand complex written or spoken instructions. He was unable to repeat sentences, produce serial speech or name common objects. He was unable to perform simple oral calculations. All of these symptoms have subsided and he now has no difficulty in answering simple questions. He is being supervised in the Neurosurgical Unit and is continuing with his Epilim for another 6 months. thrombophlebitis can occur after any operation which involves manipulation of the dura and it must be assumed that in this case thrombosis occurred in some of the vessels involving the dura and spread to the veins overlying the temporo-parietal region of his brain. There was no possible way to prevent this happening and its must be assumed that such a complication, rare as it is, cannot be due to negligence on the part of the surgeon. Summary (1) A rare complication of a radical mastoid operation is described. (2) Possible reasons for such a complication are mentioned. (3) All clinical manifestations subsided spontaneously. Acknowledgements Discussion This is a rare complication of an uncomplicated mastoid operation.
