AbstractIntroduction:‘Dead ear’ is a rare and serious complication of ear surgery. This paper presents an audit of this complication.Method:Over 6 years, data for all 617 middle-ear operations performed under the care of a single consultant were recorded for the International Otology Audit. All cases of dead ear were identified and assessed.Results:A post-operative dead ear occurred in 6 cases (approximately 1 per cent). No cases of post-operative dead ear occurred following the 83 otosclerosis operations and the 62 children's procedures. Amongst 187 adult patients undergoing mastoid surgery for cholesteatoma, there were 5 cases of post-operative dead ear (2.7 per cent of cases).Conclusion:The occurrence of dead ear after cholesteatoma surgery in adults is less rare than previously thought. This has implications for the surgical consenting process. The current series suggests that, whilst dead ear is often avoidable, it is sometimes inevitable.

Conductive Hearing

We recorded auditory-evoked magnetic responses with a whole-scalp 122-channel neuromagnetometer from seven adult patients with unilateral conductive hearing loss before and after middle ear surgery. The stimuli were 50-msec 1-kHz tone bursts, delivered to the healthy, nonoperated ear at interstimulus intervals of 1, 2, and 4 seconds. The mean preoperative pure-tone average in the affected ear was 57 dB hearing level; the mean postoperative pure-tone average was 17 dB. The 100-msec auditory-evoked response originating in the auditory cortex peaked, on average, 7 msecs earlier after than before surgery over the hemisphere contralateral to the stimulated ear and 2 msecs earlier over the ipsilateral hemisphere. The contralateral response strengths increased by 5% after surgery; ipsilateral strengths increased by 11%. The variation of the response latency and amplitude in the patients who underwent surgery was similar to that of seven control subjects. The postoperative source locations did not differ noticeably from preoperative ones. These findings suggest that temporary unilateral conductive hearing loss in adult patients modifies the function of the auditory neural pathway. (Otolaryngol Head Neck Surg 1998;119:125-30.)

AbstractA prospective trial was performed to ascertain the value of head dressings in the post-operative management of patients undergoing middle ear and mastoid surgery. One hundred consecutive patients were randomly allocated to a head dressing or no head dressing group after wound closure.Nine patients in the head dressing group developed a wound complication as opposed to four patients in the no head dressing group.The application of a pressure dressing following middle ear and mastoid surgery is unnecessary and may contribute to increased wound morbidity.

Mastoid Surgery

Background: Mastoid surgery is one of the commonest surgeries in Otolaryngology & Head & Neck department. Surgeons are less aware of preserving chorda tympani nerve (CT). Injury to the chord tympani nerve is common in middle ear surgery as the course of CT runs between ossicles and close to tympanic membrane. It makes the surgeon difficult to preserve it during the surgery. The study was done to observe frequency of taste disturbances (TD) in all patients undergoing mastoid surgery and to correlate between intra operative status of CT and type of intra operative status of CT injury with postoperative taste disturbances. Methods: A prospective analytical study was conducted in patients who underwent mastoid surgery. The intra operative status of CT was studied, different forms of injury to the nerve were noticed and its impact on taste disturbances was assessed subjectively with questionnaire. The patients with taste disturbances were followed till twelve weeks. Result: None of the patients had taste disturbances prior to surgery. Out of 65 patients, only 15 patients became symptomatic in second postoperative day and the taste disturbances were in the form of altered taste (26.66%), dry mouth (26.66%) and numbness (46.66%). Symptoms like altered taste and numbness were present till the eighth week of surgery and disappeared by the twelfth week except one patient in whom numbness persisted till twelfth week. The symptoms did not correlate with the intra operative status of CT. The symptoms disappeared with duration of operation and it was significant. Conclusion: None of the patients voluntarily complained regarding taste disturbances until they were specifically asked. Only 15 patients had taste disturbances; 7 had numbness, 4 dryness of mouth and 4altered taste. The taste disturbances did not correlate with the type of intra operative status of CT. CT was not identified in 9 patients and only 3 (33.3%) became symptomatic and CT was cut with micro scissors in 26 patients but only 4 (15.38%) patients were symptomatic.

Cholesteatoma Surgery

<p class="abstract"><strong>Background:</strong> Endoscope assisted ear surgery (EAES) reduces the chances of residual cholesteatomas as compared to the conventional microscopic technique, primarily because of the direct visualization of sites where residual cholesteatoma is common, which is often missed out during the traditional microscopic surgical procedure. The aim of the study was to evaluate the hidden areas of middle ear using endoscopes during the conventional microscopic cholesteatoma surgery.</p><p class="abstract"><strong>Methods:</strong> The present prospective study was carried out in the Dept. of Otorhinolaryngology and Head &amp; Neck Surgery, Shri Mata Vaishno Devi Narayana Superspeciality Hospital, Katra, Jammu for a period of one year during which a total of 20 patients of acquired cholesteatoma who underwent conventional microscopic surgery were followed by oto-endoscope assisted examination were enrolled.  </p><p class="abstract"><strong>Results:</strong> Otoendoscope was used in all the surgeries to look for residual cholesteatoma in the hidden areas like protympanum, sinus tympani and anterior attic. An overall incidence of cholesteatoma observed and removed from hidden areas using otoendoscope was recorded to be 30% in the present study.</p><p class="abstract"><strong>Conclusions:</strong> Microscopic ear surgery assisted with oto-endoscope allows a better visualization of the extent of cholesteatoma and thus improved eradication of residual/recurrent disease from the hidden areas of middle ear such as facial recess, sinus tympani, anterior epitympanic space, protympanum and hypotympanum.</p>

Objective: To review the clinical experience for non-shaved middle ear/mastoid surgery and evaluate the proper method of preparing the postauricular surgical field. Methods: This retrospective study reviewed medical records of cases where the non-shaved surgical procedure was carried out for middle ear/mastoid diseases. In all cases, middle ear and mastoid surgery was performed by one otologic surgeon without hair shaving to treat chronic perforation of tympanic membrane, as well as chronic suppurative otitis media, with or without mastoiditis during two years. The prevalence of surgical site infection (SSI) and bacterial culture of the surgical field was assessed just before the skin incision. Results: In this review of 106 cases, the SSI rate was 1.6% for the non-shaved ear surgery. Bacterial colonisation was found on the prepared surgical field in 8.5% of cases and these bacteria was different from true pathogens. SSI of the skin incision occurred in two cases, although no bacterial colonisation of the non-shaved surgical field was found. The surgical exposure of postauricular area was enough to do tympanoplasty or tympanomastoidectomy, even though in cases where a hairline was close to postauricular sulcus. Conclusion: This study showed that when preparing the non-shaved ear surgery, the surgeons should not have to worry about skin contamination by hair. We suggest that the non-shaved ear surgery would appear to be preferable for the postauricular approach.
