“…The success rate of tympanoplasty is affected by tube functionality, being higher when tube function is normal and vice versa (2)(3)(4)(5). Tube function can be evaluated using both static and dynamic tests (5)(6)(7)(8)(9)(10)(11). Instillations of dye, saccharine or radioactive substances via middle ear are the examples of static tests.…”

Objectives: The aim of the present study was to examine the levels of complete blood count (CBC) parameters (Neutrophil, lymphocyte, platelets, MPV, NLR, and PLR) in patients with both perforated eardrums and dysfunctional eustachian tubes to determine which of these parameters might be reliable biomarkers of chronic otitis media prior to surgery, as inflammation is significant component of middle ear pathology. Materials and methods: In this study, we enrolled 95 patients with 18-65 years old. Patients with chronic otitis media (perforated tympanic membranes) more than three months in duration who have no draining ears, were enrolled in Okmeydani Training & Research Hospital. Patients were divided into three groups: Group 1 is “Open eustachian tube” group in which pressure changes (if evident) during swallowing were recorded on stepladder-type graphs; Group 2 is “Blocked” group, who could not neutralize the negative pressure even by repeated swallowing. Group 3 is “Partially blocked” group in whom some residual pressure persisted even after five swallows. The groups were compared in terms of laboratory tests. Results: There was a statistically significant difference between 3 groups in terms of platelet levels (p>0.05). We found that group 2 / blocked eustachian tube had significantly increased platelet counts values when compared to the group 1 and 3. There was no significant difference among group 1 and group 3. There was no statistically significant difference between the 3 groups in terms of neutrophil, lymphocyte count, MPV, NLR, PLR levels, bone and air hearing thresholds. Conclusion: We found that the platelet count increased in chronic otitis media patients with blocked eustachian tube. This may be a simple and inexpensive biomarker with acustic impedencemeter tests supporting eustachian dysfunction before tympanoplasties. Key Words: Hematological biomarkers; eustachian tube dysfunction; chronic otitis media

Kurein et al also noted that the inflation-deflation test could be used in the former to avoid unnecessary exploration of the mastoid [1]. Indeed, the inflation-deflation test is a classical diagnostic test in otolaryngology.…”

Objectives: To identify the predictors of anatomical and functional outcomes following tympanoplasty.Study Design: A retrospective cohort study.Methods: Patients with chronic suppurative otitis media (CSOM) who underwent a tympanoplasty at Peking Union Medical College Hospital from January 1, 2015 to December 31, 2019 were retrospectively included. Outcome measures included graft success and postoperative pure tone audiometry air-bone gap (PTA-ABG) at last follow-up (≥6 months). PTA-ABG and MERI were calculated. Descriptive, univariable, and multivariable logistic regression analyses were conducted to evaluate the predictors of the graft and hearing outcomes.Results: During the study, 385 patients (167 male, 218 female, median age 44 years) undergoing 413 procedures were studied. Out of this, 219 ears underwent tympanoplasty, 45 ears had tympanoplasty with canal wall up mastoidectomy, and 149 ears had tympanoplasty with canal wall down mastoidectomy. At the last followup, the overall graft success rate was 91.3% (377/413) and the overall hearing success rate was 40% (165/413). Multivariable analysis results showed that the obstructed aditus ad antrum (OR 2.67, 95%CI 1.13-6.30; P = .025) was an independent prognostic factor for graft failures. Moreover, the obstructed aditus ad antrum (OR 2.18, 95%CI 1.16-4.08; P = .015) and MERI >3 (OR 6.53, 95%CI 3.55-12.02; P < .001) were independent predictors of hearing failures (PTA-ABG > 20 dB).Conclusions: Aditus ad antrum patency was an independent predictor of both graft and hearing success among patients following tympanoplasty. MERI score greater than three was found to be a significant predictor of postoperative hearing and could serve as a useful tool for assisting clinicians in perioperative risk assessment.
