Abstract
INTRODUCTION This study investigated the effect of sound therapy combined with drug therapy (SDT) on gap detection threshold and speech recognition scores in patients with sudden sensorineural hearing loss (SSNHL). METHODS Patients with SSNHL were grouped randomly into SDT and drug therapy (DT) groups. All patients received standard drug treatment and patients in the SDT group additionally received sound stimulation for the affected ears for 6 days. Pure tone audiogram, speech recognition scores at normal and time-compressed rates under quiet and noisy conditions, and the gap detection threshold of the SDT and DT groups before treatment and on day 6 and 30 after treatment were compared. RESULTS There were 20 patients in the SDT group and 24 in the DT group. The pure tone thresholds of affected ears were significantly lower in the SDT group on day 6 after treatment than those in the DT group at 125 and 250 Hz. Significantly lower gap detection thresholds and higher speech recognition scores under noisy conditions were observed at the normal and time-compressed rates in the SDT group than those in the DT group on day 6 and 30 after treatment. Significant correlations were observed between the gap thresholds and speech recognition scores in a noisy environment at normal and time-compressed rates on day 6 and 30. CONCLUSIONS SDT may improve the recovery of hearing abilities, such as the gap in noise thresholds and speech recognition in noise, in the case of SSNHL. TRIAL REGISTRATION NUMBER ChiCTR-IOR-17012262.

Abstract
OBJECTIVE To explore the association between platelets or leukocytes and tinnitus. DESIGN A meta-analysis and scoping review examining the association between tinnitus and platelets and leukocytes. All 11 studies included were critically appraised using the Joanna Briggs Institute (JBI) checklist (2017a). A random effects model was used to pool the results of the studies examining mean platelet volume (MPV) and tinnitus. STUDY SAMPLE 1935 studies were identified in the initial search, 11 of which were included in the scoping review. 6 of the 11 studies had their MPV values pooled in the meta-analysis. RESULTS Pooled results of 818 subjects from 6 studies indicated that MPV was significantly higher in those with tinnitus compared to a comparison group without tinnitus. The overall mean difference was 0.43 fL with a 95% confidence interval (CI) from 0.31 to 0.55 and a p value of < 0.0001 which was statistically significant. MPV is the only haematological parameter which is reliably associated with tinnitus. CONCLUSIONS MPV could be a useful biomarker for tinnitus. Further studies should aim to standardise methodology with more rigorous exclusion criteria to reproduce and define this association. NLR, PLR, WBC count, RDW and PDW do not show a reliable association with tinnitus.

Abstract
BACKGROUND We aimed to evaluate the association between mean platelet volume, platelet distribution width (PDW), platelet count (PC) and plateletcrit (PCT), and the presence of sudden sensorineural hearing loss (SSNHL) and treatment response. In the literature, there is no study that investigates the platelet functions in diabetic patients with SSNHL. METHODS The patients were retrospectively assigned into Group 1 (68 diabetic patients with SSNHL), Group 2 (63 nondiabetic patients with SSNHL) and Group 3 (64 healthy controls). RESULTS PC was not significantly different between the groups (p > 0.05). MPV, PDW and PCT values were significantly higher in Group 1 as compared to Groups 2 and 3 (p < 0.05). Platelet parameters were not significantly different between the patients who were responsive and nonresponsive to the treatment. Therefore, the platelet parameters did not affect prognosis significantly in this study samples (p > 0.05). CONCLUSIONS This study showed that platelet parameters did not have a significant effect as a prognostic and predictive value in diabetic and nondiabetic patients with SSNHL. Further studies with more homogenous and larger study groups investigating the platelet parameters are needed to demonstrate microvascular damage and vascular alterations induced by diabetes mellitus.

Abstract
Objective Recent studies have shown that chronic inflammation contributes to the development of sudden sensorineural hearing loss (SSNHL). Some hematologic parameters have also been linked to the prognosis of SSNHL. However, the prognostic value of such hematological factors is not conclusive. This study explored the association of routine hematological parameters with SSNHL. Methods A systematic literature search was conducted in PubMed, Cochrane Library, Web of Science and Embase to identify eligible studies. Standardized mean deviation (SMD) and the 95% confidence interval (CI) were retried from relevant studies for analysis. Heterogeneity, subgroup, and publication bias analyses were performed. Results A total of 18 studies involving 1505 SSNHL patients and 1466 healthy persons were enrolled in the final analysis. The study population included 699 responders and 458 non-responders to treatment. Pooled results revealed that the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) value in the SSNHL patient group were higher than in the healthy group (SMD = 1.05, 95% CI: 0.86,1.24, p < 0.001, SMD = 0.52, 95% CI: 0.26,0.78, p < 0.001, respectively). However, there was no significant difference in the mean platelet volumes (MPV) between the groups (SMD = 0.03, 95% CI: 0.44, 0.49, p = 0.91). Notably, NLR and PLR values were evidently higher in the unrecovered group than in the recovered group (SMD = −0.63, 95% CI: 1.02, −0.23, p = 0.002, SMD = −0.4, 95% CI: 0.76, −0.03, p = 0.03, respectively). However, the MPV value was similar in both groups (SMD = −0.35, 95% CI: 1.14,0.44, p = 0.38). Conclusions Our results show that NLR and PLR values can predict the onset and prognosis of SSNHL.

Abstract
Objectives:
The purpose of this study was to investigate relation
between mean platelet volume, platelet distribution width, platelet-to-lymphocyte
ratio, neutrophil-to-lymphocyte ratio and vestibular migraine. Methods: This study was planned in prospective
manner and conducted
in Ankara Polatlı State Hospital between April 2017 and May 2018. Thirty patients
diagnosed with vestibular migraine and thirty healthy, age and sex-matched
subjects were enrolled to the study. Mean platelet volume, platelet
distribution width, platelet count, neutrophil count and lymphocyte count in
blood samples were measured. Results: The mean age of the patients with vestibular
migraine was 39.90 ± 7.16 and the study group consisted
of 11 males and 19 females. The mean platelet volume and platelet
distribution width values in patients with vestibular
migraine were significantly higher than the control group
(p < 0.001). There were no difference
on mean neutrophil/lymphocyte ratio and platelet/lymphocyte ratio values between
patient group and control group.
Conclusions: We found a positive relation of
increased levels of mean
platelet volume and platelet distribution width with vestibular
migraine. Higher mean platelet volume is associated with atherosclerosis and thromboembolism.
Vascular pathologies are blamed for both headache syndromes like migraine and vertiginous
syndromes. This theory supports our study but pathophysiological mechanism is
not clear.

Abstract
PURPOSE In this study, we aimed to investigate whether there is any positive or negative correlation between high-frequency distortion product otoacoustic emission (DPOAE) values and mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR) in tinnitus patients. METHODS The study was performed with 52 volunteers (27 females, 25 males) aged between 35 and 50 years who presented with tinnitus to the otolaryngology outpatient clinic of a tertiary care center. Pure voice audiometric examination, DPOAE measurement, complete blood count values of the study participants were examined. RESULTS In both ears, a significant and negative correlation was observed between 4000 and 8000 Hz airway and 4000 Hz bone conduction pathways with NLR rates (p < 0.05). A statistically significant relationship was found between the bone conduction pathway PTA and discrimination values for both ears and NLR s (p < 0.05). A positive correlation was detected between NLRs and DPOAE measurements recorded at 4444 Hz, 5000 Hz, 8000 Hz, 8889 Hz, 10,000 Hz and 11,429 Hz frequencies in the right and 4444 Hz, 5000 Hz, 6154 Hz, 8000 Hz, 10,000 Hz and 11,429 Hz frequencies in the left ears, respectively (p < 0.05). CONCLUSIONS We concluded that there is a significant correlation between high-frequency pure tone audiometry measurements and high frequency DPOAE measurements and NLR. Further studies are needed to determine the utility of NLR as a marker for the recognition and follow-up of hearing loss in patients with tinnitus.

Abstract
AIM To evaluate the alterations in inflammatory markers, NLR and PLR, as well as mean platelet volume (MPV) and the other parameters of complete blood counts (CBC) in adult patients with vestibular neuritis (VN). METHOD Designed as a case control study. The records of the patients, who were hospitalized due to an acute onset vertigo, and diagnosed as VN, were analysed retrospectively. The complete blood count (CBC) measures of the patients were statistically compared with the measures of healthy subjects. The correlations between the length of hospitalization and the neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were also analysed. RESULTS One hundred four patients with VN and 138 healthy controls were included. MPV, white blood cell and neutrophil counts, NLR and PLR were significantly higher; while lymphocyte count was significantly lower in the VN group (p < 0.001). There were no correlations between the length of hospitalization and NLR or PLR. CONCLUSION The elevations of NLR and PLR support the role of inflammation in VN. The high level of MPV indicates the possible role of the vascular thrombosis in the etiology of VN.

Abstract
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.

Abstract
Recent years, the discussion about whether platelets participant in the development of sudden sensorineural hearing loss (SSHL) continues and many studies on the relationship between them have come to our attention. Some studies believe that platelet parameters have significantly changed in patients with SSHL, while some not, controversially. Therefore, to investigate the association between platelet parameters, including mean platelet volume (MPV), platelet distribution width (PDW) and platelet count (PLT), and SSHL, expecting to resolve controversy and provide clinical evidence for diagnosis and monitoring of SSHL. Basic methods: Literature was retrieved searching electronic databases (PubMed, Embase, Cochrane, and Scopus) and searching references of related articles by hand. A total of 18 case-control studies involving 1837/1734 subjects (SSHL/control) were included. Meta-analysis showed there was no difference between the patients who suffered SSHL and healthy controls in MPV level [standard mean difference (SMD) (95% confidence interval (CI)) = 0.16 (-0.07, 0.40), I2 = 80%, P<0.00001] and PLT [SMD (95% CI) = -0.03(-0.18, 0.12), I2 = 73%, P<0.00001]. While PDW exhibited significant difference [SMD (95% CI) = 0.85 (0.20, 1.49), I2 = 93%, P<0.00001]. Subgroup analysis about geographical area suggested PLT have obvious evidence for SSHL in Eastern country [SMD (95% CI) = 0.23 (0.14, 0.33), I2 = 0%, P=0.81]. Our study did not support a correlation between MPV and SSHL, while PLT may have clinical significance for SSHL in Eastern country. With insufficient data to explore the resource of heterogeneity for PDW, there is no decisive conclusion reached.

Abstract
We explored possible relationships between sudden sensorineural hearing loss (SSNHL) in patients differing in terms of audiographic data and the levels of vascular markers in routine blood data.We included 37 patients with low-frequency SSNHL (LF-SSNHL), 28 with high-frequency SSNHL (HF-SSNHL), 32 with all-frequency SSNHL (AF-SSNHL), 32 with total-deafness SSNHL (TD-SSNHL), and 31 age- and sex-matched healthy controls. Peripheral venous blood samples were collected, and routine blood parameters including platelet and lymphocyte count, mean platelet volume (MPV), and platelet-to-lymphocyte ratio (PLR) were measured. Each group was divided into recovery subgroup and unrecovery subgroup in accordance with hearing level after 1 month therapy, then compared the difference of platelet and lymphocyte count, MPV, and PLR between the 2 subgroups.No significant difference was observed between platelet count of all SSNHL patients and control group (all P > .05). MPV of AF-SSNHL and TD-SSNHL, PLR of all SSNHL patients were significantly higher than those of control group (all P < .05), while lymphocyte count of all audiographically distinct SSNHL patients was significantly lower than that of control group (all P < .05). However, the difference of platelet count, lymphocyte count, MPV, and PLR among audiographically distinct SSNHL patients was not significant (all P > .05). In HF-SSNHL patients, lymphocyte count of unrecovery subgroup was significantly lower, while MPV and PLR of the unrecovery subgroup were significantly higher than those of recovery subgroup (all P < .05). In AF-SSNHL patients, MPV of the unrecovery group was significantly higher than that of recovery subgroup (P < .05).Lymphocyte count, MPV, and PLR may be relative to SSSNHL, but they could not be used to distinct SSNHL audiographically. Lower lymphocyte, higher MPV, and PLR may be indicative for the prognosis of HF-SSNHL patients; higher MPV may be related to bad treatment outcome of AF-SSNHL patients.

MATERIALS AND METHODS Twenty-three ISSNHL patients were included in the study (group A). The control group was consisted of 19 patients (group B). Procalcitonin and hs-CRP levels were compared between the groups. The relationship between procalcitonin and hs-CRP levels and the configuration of the audiogram, degree of hearing loss [partial or total ( > 90 dB)], and status of improvement (improvement of > 15 dB in the first month PTA) were evaluated. RESULTS The mean age was 47.91±15.73 years (range 21-73 years) and 35.16±15.67 years (range 19-79 years) in groups A and B, respectively. Seven patients (30.4%) had underlying cardiovascular risk factors. Mean procalcitonin levels were 0.057±0.025 µg/L and 0.041±0.016 µg/L in groups A and B, respectively. Mean hs-CRP levels were 0.461±1.335 mg/dL and 0.129±0.125 mg/dL in groups A and B, respectively. Procalcitonin levels were significantly higher in group A than in group B (p=0.018). Procalcitonin levels were significantly lower (0.035±0.013 µg/L vs. 0.061±0.025 µg/L) in patients with low-frequency hearing loss (p=0.04). ROC analysis of procalcitonin values revealed that area under the curve was 0.80 (p=0.005). A cut-off procalcitonin level of 0.45 µg/L yielded a sensitivity of 90% and specificity of 56.2%. CONCLUSION In conclusion, as a proinflammatory marker, procalcitonin levels were higher in ISSNHL patients than in healthy controls. The procalcitonin level was significantly lower in upsloping-type hearing loss patients. This finding could be regarded as an indirect indicator of pathogenesis.

Abstract
Background: The prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL. Methods: One hundred and thirty-six CSSNHL patients treated in Department of Otolaryngology-Head and Neck Surgery and Institute of Otolaryngology at Chinese PLA General Hospital between July 2008 and August 2015 were included in this study. These patients were analyzed for clinical characteristics, audiological characteristics, laboratory examinations, and prognostic factors. Results: Among the 136 patients (151 ears), 121 patients (121 ears, 80.1%) were diagnosed with unilaterally CSSNHL, and 15 patients (30 ears, 19.9%) with bilateral CSSNHL. The complete recovery rate of CSSNHL was 9.3%, and the overall recovery rate was 37.7%. We found that initial degree of hearing loss, onset of treatment, tinnitus, the ascending type audiogram, gender, side of hearing loss, the recorded auditory brainstem response (ABR), and distortion product otoacoustic emissions (DPOAEs) had prognostic significance. Age, ear fullness, and vertigo had no significant correlation with recovery. Furthermore, the relevant blood tests showed 30.8% of the children had abnormal white blood cell (WBC) counts, 22.1% had elevated homocysteine levels, 65.8% had high alkaline phosphatase (ALP), 33.8% had high IgE antibody levels, and 86.1% had positive cytomegalovirus (CMV) IgG antibodies. Conclusions: CSSNHL commonly occurs unilaterally and results in severe hearing loss. Initial severe hearing loss and bilateral hearing loss are negative prognostic factors for hearing recovery, while positive prognostic factors include tinnitus, gender, the ascending type audiogram, early treatment, identifiable ABR waves, and DPOAEs. Age, vertigo, and ear fullness are not correlated with the recovery. Some serologic indicators, including the level of WBC, platelet, homocysteine, ALP, positive CMV IgG antibody, fibrinogen, and some immunologic indicators, are closely related to CSSNHL.

Abstract
CONCLUSION The elevated neutrophil-to-lymphocyte ratio (NLR) value in children with sudden sensorineural hearing loss (SSNHL) would suggest the inflammatory etiology of pediatric SSNHL. The results of this study may suggest NLR value can be used as a useful indicator, which is associated with the disease severity in pediatric SSNHL. OBJECTIVES This study aimed to elucidate any clues of inflammatory etiology, which might be related with the development of pediatric SSNHL, using calculated NLR. METHODS Forty-six patients aged younger than 19 years, who were admitted to the hospital with the diagnosis of SSNHL, were included in the study. Forty-six healthy children were matched as control group according to their propensity score. The complete blood cell count, calculated NLR, platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) were compared. The relationship between NLR and the initial hearing level was also investigated. RESULTS The mean NLR value was 2.86 ± 2.58 in the SSNHL group, whereas the mean NLR value was 1.63 ± 0.87 in the control group. The mean NLR value of the SSNHL children was significantly higher than that of the control group (p = .023). There was a positive correlation between the NLR value and initial hearing level (r = .312, p = .037).

Abstract
Tinnitus is the perception of sound with no external stimulus and idiopathic subjective tinnitus is the most common type in adults. Mean platelet volume (MPV) alterations were shown in some inflammatory diseases and were evaluated as a clinically useful marker. Our aim was to investigate MPV alterations in idiopathic subjective tinnitus patients. A total of 101 patients and 54 age- and sex-matched healthy control subjects were enrolled in the study. Patients included in the study had complaints of tinnitus for at least 3 months. All patients underwent detailed otolaryngologic examination, blood sampling, pure tone audiometry, magnetic resonance imaging of ear, and vertebrobasilar artery Doppler ultrasonography to make the differential diagnosis of tinnitus. Blood sampling consisted of renal-liver-thyroid function tests, lipid profile, and complete blood count. All tests and examinations except the imaging modalities were also performed for the control group. There were no differences in age and sex distribution of groups. Mean platelet volume values were significantly increased in tinnitus patients when compared with controls (p = 0.001). We think that MPV can be qualified as a useful marker in tinnitus patients.

Abstract
Sudden sensorineural hearing loss (SSNHL) is a common otological disorder characterized by a hearing loss greater than 30 dB over three consecutive frequencies, in less than 72 hours. It has been established that platelet parameters, such as mean platelet volume, are associated with ischemic heart events, whose clinical manifestations are similar to those of SSNHL. Hence, we aimed to determine if the platelet count, mean platelet volume and platelet distribution width are related to the occurrence and severity of sudden sensorineural hearing loss. A case-control prospective study was conducted in a teaching hospital in Iran. One hundred-eight patients with SSNHL and an equal number of healthy, age- and sex-matched controls were enrolled in the study. Peripheral venous blood samples were collected from the subjects, and the platelet count, mean platelet volume and platelet distribution width were measured with an automated blood cell counter. Analysis of the audiometry and hematological test results using SPSS22 software showed no statistical correlation between the platelet parameters and the occurrence of SSNHL, but correlation coefficients showed a significant correlation between PDW and hearing loss severity in patients group. However, further investigation is required to unequivocally establish the absence of correlation between the platelet parameters and occurrence of SSNHL.

Abstract
OBJECTIVE This study aimed to determine whether there was any relationship between tinnitus and mean platelet volume. METHODS This retrospective study was conducted between January 2013 and January 2014 in Ankara Atatürk Hospital and Ondokuz Mayıs University Hospital, Turkey, on a study group of 86 patients with tinnitus and a control group of 84 healthy subjects. Mean platelet volume was recorded and comparisons were made between the two groups. RESULTS Mean (± standard deviation) platelet volume was 7.67 ± 0.83 μm(3) in the study group and 7.28 ± 0.56 μm(3) in the control group. There was a statistically significant difference in mean platelet volume between the tinnitus patients and the healthy subjects (p < 0.05). CONCLUSION The clinical findings indicated that tinnitus patients had a higher mean platelet volume than the healthy control subjects; however, the pathophysiological mechanism remains unclear.

Abstract
Introduction Several theories attempt to explain the pathophysiology of sudden hearing loss. Objective The objective of this study was to investigate the possible role of inflammation and atherothrombosis in sudden hearing loss patients through the neutrophil-to-lymphocyte ratio and mean platelet volume. Methods Study design – retrospective cross-sectional historical cohort. This study was conducted on two groups: one with 59 individuals diagnosed with sudden hearing loss, and other with 59 healthy individuals with the same characteristics of gender and age distribution, neutrophil-to-lymphocyte ratio and mean platelet volume levels were measured in patients diagnosed with sudden hearing loss as well as in the control group, and it was verified whether these results interfered for a better or worse prognosis with treatment of sudden deafness. Results Neutrophil-to-lymphocyte ratio levels are much higher in patients diagnosed with sudden hearing loss compared to the control group. Similarly, mean levels of neutrophil-to-lymphocyte ratio are higher in non-recovered versus recovered patients (p = 0.001). However, we could not find a correlation with mean platelet volume levels (p > 0.05). Conclusion Neutrophil-to-lymphocyte ratio is a quick and reliable indicator regarding diagnosis and prognosis of sudden hearing loss; on the other hand, mean platelet volume may be considered a less important indicator in this aspect.

Abstract
OBJECTIVE The aim of this study was to investigate the role of inflammation and atherothrombosis in Bell's palsy (BP) by using neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV), respectively, and to study their relations with the facial nerve enhancement on temporal gadolinium-enhanced magnetic resonance imaging (TGd-MRI). STUDY DESIGN Case control study. SETTING Tertiary health institution. SUBJECTS AND METHODS This study was performed on 65 patients who were diagnosed with BP and a control group of 35 healthy individuals. The BP patients were also divided into 2 groups, those with facial nerve enhancement on TGd-MRI and those without enhancement. The NLR and MPV of each group were compared. RESULTS The NLRs of the BP patients were significantly higher than control group (P = .001). The NLRs of patients with facial nerve enhancement on TGd-MRI were significantly higher than patients without enhancement (P = .001). There was a positive and significant correlation between NLR and House-Brackmann (HB) grade of the patients (r = 0.641; P < .05). MPV did not show any significant correlation with any of the parameters studied (P > .05). CONCLUSION NLR can be used as a new and important marker in BP since it is high in BP patients and significantly correlated with HB grade and facial nerve enhancement on TGd-MR. On the other hand, MPV does not have such correlations. These results offer evidence to support an inflammatory theory rather than microvascular response theory in the etiopatogenesis of BP.
