Assessment of inflammatory markers in otosclerosis patients

Introduction

Otosclerosis is an idiopathic disease characterized by new bone formation in foci of the human otic capsule. It is more common in Caucasian populations; affecting females twice as often as males. Its etiopathogenesis has not yet been fully elucidated.

Objective

The aim of this study was to investigate the relationship between otosclerosis and white blood cell and thrombocyte counts, mean platelet volume, neutrophil lymphocyte ratio, and the platelet lymphocyte ratio.

Methods

This retrospective case-control study was conducted in the outpatient clinic Mustafa Kemal University, in the department of otolaryngology, between 2015 and 2018. A total of 30 patients with an established diagnosis of otosclerosis were compared to a control group of 30 healthy subjects, matched for age, gender and body mass index. The white blood cell, thrombocyte, mean platelet volume, neutrophil lymphocyte ratio and platelet lymphocyte ratio values were calculated for all participants.

Results

There was no statistically significant difference between the groups with respect to age, gender, or body mass index, or for the mean neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell, or thrombocyte values (p > 0.05). A statistically significant difference was determined between the groups for the mean platelet volume values. The mean platelet volume values were lower in the otosclerotic patients (p = 0.047).

Conclusion

These results show that neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell and thrombocytes should not be used to predict otosclerosis, but suggest that mean platelet volume may be a negative predictive marker.

Does stapes surgery improve tinnitus in patients with otosclerosis?

Introduction

Otosclerosis (OS) is the primary disease of the human temporal bone characterized by conductive hearing loss and tinnitus. The exact pathogenesis of tinnitus in otosclerosis patients is not known and factors affecting the tinnitus outcome in otosclerosis patients are still controversial.

Objectives

To find the effect of stapedotomy on tinnitus for otosclerosis patients.

Methods

Fifty-six otosclerosis patients with preoperative tinnitus were enrolled to the study. Pure tone average Air-Bone Gap values, preoperative tinnitus pitch, Air-Bone Gap closure at tinnitus frequencies were evaluated for their effect on the postoperative outcome.

Results

Low pitch tinnitus had more favorable outcome compared to high pitch tinnitus (p = 0.002). Postoperative average pure tone thresholds Air-Bone Gap values were not related to the postoperative tinnitus (p = 0.213). There was no statistically significant difference between postoperative Air-Bone Gap closure at tinnitus frequency and improvement of high pitch tinnitus (p = 0.427). There was a statistically significant difference between Air-Bone Gap improvement in tinnitus frequency and low pitch tinnitus recovery (p = 0.026).

Conclusion

Low pitch tinnitus is more likely to be resolved after stapedotomy for patients with otosclerosis. High pitch tinnitus may not resolve even after closure of the Air-Bone Gap at tinnitus frequencies.

Association of tinnitus and hearing loss in otological disorders: a decade-long epidemiological study in a South Indian population

INTRODUCTION

Tinnitus is a common disorder that occurs frequently across all strata of population and has an important health concern. Tinnitus is often associated with different forms of hearing loss of varying severity.

OBJECTIVE

The present study aimed to identify the association of tinnitus with hearing loss in various otological disorders of a South Indian population.

METHODS

A total of 3255 subjects referred to the MAA ENT Hospital, Hyderabad, from 2004 to 2014, affected with various otological diseases have been included in the present cross-sectional study. Diagnosis of the diseases was confirmed by an ear, nose, and throat (ENT) specialist using detailed medical and clinical examination. Statistical analysis was performed using the χ² test and binary logistic regression.

RESULTS

Tinnitus was observed in 29.3% (956) of the total study subjects that showed an increased prevalence in greater than 40 years of age. There was a significant increase in risk of tinnitus with middle (OR=1.79, 95% CI=1.02-3.16) and inner (OR=3.00, 95% CI=1.65-5.45) inner ear diseases. It was noted that 96.9% (n=927) of the tinnitus subjects was associated with hearing loss. Otitis media (60.9%), presbycusis (16.6%) and otosclerosis (14.3%) are the very common otological disorders leading to tinnitus. Tinnitus was significantly associated with higher degree of hearing loss in chronic suppurative otitis media (CSOM) subjects.

CONCLUSION

The present study could identify the most prevalent otological risk factors leading to development of tinnitus with hearing loss in a South Indian population.
