Otorhinolaryngologists throughout the UK routinely perform middle ear operations. Although the risk of serious complications in the hands of a well-trained surgeon is very low, some of the complications of middle ear surgery are devastating to the patient viz. facial nerve palsy and complete hearing loss. The subject of informed consent is highly topical because of clinical governance and medico-legal implications. We have audited the practice of the Consultant members of the British Association of Otorhinolaryngologists-Head and Neck Surgeons via a postal questionnaire with regards to their consenting process prior to middle ear operations. Our study looked at the practice of discussing different complications and the complication rates, the person consenting, time spent on consenting, and the documentation. We found that wide variations exist in the consenting process. The implications of the results are discussed. This study is particularly pertinent at the present time with the implementation of the new consenting standards document published by the Department of Health.
We examined 395 temporal bones with an intact tympanic membrane to explore the relationship between residual inflammation in the middle ear cavity and development of mastoid pneumatization. Histopathological changes were studied in the middle ear cavity. Mastoid pneumatization was classified as good or poor based on the extent of mastoid tip development to the lateral semicircular canal. Specimens were 344 temporal bones with well-pneumatized mastoid and 51 with poorly-pneumatized mastoid. Otitis media was noted in 119 (34.6%) bones in the good group and 9 (17.6%) in the poor group. In well-pneumatized mastoid, chronic inflammatory changes were frequently observed at the lower portion of mastoid cells, the round window niche, and the tympanic sinus. In contrast, no such incidence of inflammatory change was noted in poorly-pneumatized mastoid. Our findings indicate that an intact tympanic membrane does not always mean freedom from mastoid inflammation, especially when the mastoid is well-pneumatized. This makes it important to check for possible remaining otitis media in patients with a well-pneumatized mastoid, even if the tympanic membrane appears normal.
