The procedure of mastoidectomy and epitympanotomy effected a two-year arrest of serous otitis media and correction of a refractory retraction pocket in 12 out of 20 patients with one patient lost to follow-up. Each mastoid and epitympanum was extensively involved with chronically inflamed tissue which surrounded the ossicles and chorda tympani nerve.

AbstractObjective:We investigated gustatory changes in patients with chronic otitis media, before and after middle-ear surgery.Methods:This prospective study included 38 patients with unilateral chronic otitis media. We used taste testing solutions to evaluate each patient's taste function. Intra-operative assessments of the chorda tympani nerve were also compared and analysed.Results:Patients with chronic otitis media had significantly worse ipsilateral perception of sour, bitter and salty tastes. In patients with good intra-operative preservation of the chorda tympani nerve, there was significant improvement in gustatory function one month post-operatively, compared with the pre-operative baseline. In patients who sustained intra-operative chorda tympani nerve injury, one month post-operative gustatory function was the same as the pre-operative baseline.Conclusion:Middle-ear surgery for chronic otitis media not only treats the ear but also improves gustatory function in the majority of patients. In patients with intra-operative injury to the chorda tympani nerve, post-operative taste decline is only temporary.

AbstractObjective:To determine the immediate and long-term taste effects of chorda tympani nerve sacrifice in patients undergoing open cavity mastoidectomy.Design, setting and participants:A retrospective, questionnaire survey of patients receiving follow up and aural toilet following open cavity mastoidectomy, over a four-month period. The questionnaire assessed taste disturbance, both immediately post-operative and current. Available surgical records were reviewed for chorda tympani references.Results:Of 57 patients, six had undergone surgery to both ears. Of those who could recall (37/57), 24.3 per cent were aware of taste disturbance immediately after surgery, while 8.7 per cent reported current disturbance (median post-operative interval, 28.5 years; range, one month to 67 years). No bilateral surgery patients were aware of taste disturbance.Conclusion:Mastoidectomy consent procedure emphasises the risk of hearing loss and facial nerve injury, yet in open cavity surgery chorda tympani division is almost inevitable. Reassuringly, most post-operative taste disturbance resolves, and most patients are not aware of long-term disturbance. However, a small percentage suffer ongoing taste disturbance; this could be significant for professional chefs and wine-tasters. The risk of taste disturbance should be addressed in the consent procedure.

A Prospective Study

Objective To study the effect of chronic inflammatory middle ear disease on gustatory function of chorda tympani nerve. Methods A prospective study was performed in 2007 on 85 patients of unilateral chronic inflammatory middle ear disease of both cholesteatomatous and noncholesteatomatous type. Gustatory assessment on both sides of the tongue was performed using dry taste strips. Taste strips were made of filter paper soaked in four different taste solutions of four different concentrations each and dried. The taste score is the number of correctly identified taste strips. Results were analyzed using Analysis of Variance (ANOVA) and t-test. Results Comparison of mean taste scores on the side of diseased ear with normal ear was done. On the diseased side, the mean taste score was 9.16 and on the normal side, the mean taste score was 13.24. The difference between the two was found to be statistically significant (p<0.0001). The results were also analyzed for various other parameters like type, duration, and location of disease. Site of cholesteatoma was found to have a significant effect on the taste score of the diseased side. Patients having postero-superior retraction pocket cholesteatoma had significantly lower taste scores as compared to those having cholesteatoma at other sites (p=0.008). Conclusions A patient of chronic inflammatory middle ear disease already has dysfunctional chorda tympani and is unlikely to notice a change in the taste sensation in the event of cutting of the nerve during the course of an ear surgery.

Objectives 1) To identify gustatory alterations due to chorda tympani nerve involvement in patients with chronic otitis media (COM) without prior surgery, and 2) To see if the presence of cholesteatoma worsened gustatory sensitivity in these patients. Methods Study Design: prospective study. The test was performed in patients with unilateral cholesteatomatous or suppurated COM not previously submitted to otological surgery. The test was based on “taste strips” with different concentrations of salt, sweet, bitter, and sour, using the otological disease-free side as the control. The score could be between 0 (worst) and 16 (best). All the other data were collected by interview and physical exam and analysed by Poisson Regression. Results A total of 45 patients with COM were evaluated, including 25 with cholesteatoma and 20 with non-cholesteatomatous COM, with a mean age of 38 years. 8 cases of unilateral ageusia were found on the affected side. The mean score was 6.65 for the affected side and 9.91 for the half of the tongue on the side of the healthy ear (p<0,05). No patients had complained of gustatory alterations before the examination. There was an association between presence of cholesteatoma and worse gustatory sensitivity (p<0.05). Conclusions Patients with cholesteatomatous or suppurated COM can present gustatory alterations, even in the absence of complaints. The presence of cholesteatoma worsened gustatory sensitivity.
