Correlation of the Neutrophil-to-Lymphocyte Ratio with the Middle Ear Risk Index in Patients with Chronic Otitis Media

Background: Chronic otitis media is a highly prevalent disease of middle ear. As tympanoplasty plays an important role in management of otitis media it is important to predict the outcome of surgery and give proper counselling to the patient. The objective of this study was to evaluate the effectiveness of Middle ear risk index (MERI) in determining postoperative graft uptake and postoperative air bone gap closure following tympanoplasty.Methods: This was a retrospective study conducted to find the correlation between MERI and the result of tympanoplasty outcome and post-operative hearing gain. Ninety-six subjects who underwent tympanoplasty for chronic otitis media were included in the study. MERI score was calculated and was compared with postoperative graft uptake and audiogram. Results: In this study there was no statistical difference in graft uptake between the MERI categories. There was statistically significant decrease in postoperative air bone gap closure in both mild and moderate categories. Other prognostic factors associated with a favourable outcome were healthy middle ear mucosa and absence of smoking.Conclusions: MERI did not have a direct impact on the outcome of surgery in terms of graft uptake and hearing results. However certain factors like Belluci’s criteria and smoking had an impact on the outcome. Hence MERI can be used for pre-operative counselling of the patients.

Hearing Outcomes

Purpose Ossiculoplasty outcome parameter staging (OOPS) and middle ear risk index (MERI) are the most commonly used indices for predicting prognosis of patients with chronic otitis media (COM). This study aimed to verify the efficiency of OOPS and MERI scores in predicting outcomes of patients with COM who underwent tympanoplasty. Methods We retrospectively reviewed the data of patients who underwent tympanoplasty (n = 526). OOPS, and MERI scores were collected. Hearing data were measured 1 day preoperatively, and 3 and 12 months postoperatively. Operation success was defined according to the Korean Society of Otology guidelines. Results For calculation of success, the ROC values of MERI were 0.551 at 12 months. ROC values of OOPS were 0.637 at 12 months. There were no significant differences in hearing variables among the three groups according to MERI. There were significantly favorable outcomes in hearing variables in the low-risk group in OOPS. The mean OOPS score was greater in patients with success than those with non-success. Otorrhea, ossicle status, and status of mucosa as variables in both indices were associated with success. The type of mastoidectomy as a variable in OOPS alone was associated with success. Absence of hypertension, presence of ossiculoplasty, and use of incus as ossiculoplasty material were associated with poor success rate. Conclusion Compared with MERI, the OOPS index was more closely associated with the hearing outcomes, which may be due to the extent of inflammation in the OOPS index.

The Impact

Background: Chronic otitis media is otological challenge in the developing countries it is particularly single most common cause of hearing impairement.Objective: The objective of this study was to observe the impact of prognostic factor middle ear risk index on hearing of patients undergoing tympanoplasty for chronic otitis media.Methods: This was a prospective analytical study conducted in 50 patients planned for tympanoplasty for chronic otitis media and evaluation done by MERI (Middle Ear Risk Index) and pure tone audiometry.Results: This study shows that most of the patients had mild MERI (64%), followed by severe MERI (20%) and then moderate MERI (16%). The mean preoperative PTA average was 44.34 dB (SD 8.01 dB) for patient with mild MERI, 44.75 dB (SD 5.87 dB) for patient with moderate MERI, and 54.9 dB (SD 14.05 dB) for patient with severe MERI and the mean preoperative A-B gap was 37.36 dB (SD 5.73 dB). Post operatively for mild MERI mean hearing gain is 12-14dB, for moderate MERI mean hearing gain is 10-13dB and for severe MERI mean hearing gain is 10-13dB and post operative mean A-B gap was improved by 10-11dB. There is a statistically significant hearing improvement in A-B gap with different types of MERI.Conclusion: MERI scoring is useful for predicating the outcome of hearing after tympanoplasty.JNGMC Vol. 13 No. 2 December 2015, Page: 6-9

Background: The middle ear cavity is ventilated through the aditus ad antrum. Aditus blockage contributes to the pathology of otitis media. Objective: To determine the normal values of the aditus ad antrum diameter on computed tomography and to investigate its relationship with chronic otitis media and related pathologies (tympanosclerosis and myringosclerosis). Methods: The temporal CT images of 162 individuals were evaluated retrospectively. In the axial sections, the inner diameter of the aditus was measured at the narrowest point at the cortex. The differences in diameter were compared between diseased and healthy ears. Results: In healthy individuals, the diameter was narrower in women. There was no difference between the right and left ears in healthy subjects. No correlation was found between age and diameter. In male patients with myringosclerosis, the diameter was slightly narrower on both sides but more marked on the left. In female patients with myringosclerosis, the diameter in both ears was slightly narrower. In cases of otitis media and tympanosclerosis, the diameter was less than that of healthy individuals, despite the lack of statistically significant result in all cases. Conclusion: The aditus ad antrum was narrower in diseased ears, indicating that a blocked aditus may contribute to the development of otitis media, as well as mucosal diseases.

Potential Danger

It is advisable to perform cautious radical operations at the same time with plasty elements. The early surgicai sanation of the middle ear is recommended allowing to preserve its elements, to increase the possibilities of reconstruction and consequently, to decrease a potential danger for acoustic function of a patient as well as for his life as a whole.
