Abstract
AIM To evaluate sleep architecture of patients with Cushing's disease (CD) and to explore whether agouti-related peptide (AgRP) and/or leptin play a permissive role in sleep alterations in patients with active CD. METHODS We performed polysomnography on 26 patients with active CD and age 26 age- and sex-matched control subjects. Blood samples were obtained from all participants for the analyzes of AgRP and leptin. The laboratory and sleep-related parameters were compared. RESULTS The groups were similar in age, gender, and body mass index. The CD group had reduced sleep efficiency (71.6 ± 12.1% vs. 78.8 ± 12.6%, p = 0.042) and increased wake after sleep onset (WASO%) (24.7 ± 13.1% vs. 17.4 ± 11.6%, p = 0.040) as compared to control group. Seventeen patients with CD (65.4%) and 18 control subjects (69.2%) had obstructive sleep apnea. Serum AgRP (13.2 ± 7.4 pg/ml vs. 9 ± 3.1, p = 0.029), leptin (59.5 mcg/l, [IQR] 32.6-94.6 vs. 25.3 mcg/l, [IQR] 12.9-57.5, p = 0.007) were higher in CD group. AgRP and leptin correlated negatively with total sleep time, sleep efficiency, stage N2 sleep (%), and positively with WASO%. In multiple regression analyses, serum cortisol (ß = - 0.359, p = 0.042) and AgRP (ß = - 0.481, p = 0.01) were significant predictor of sleep efficiency. AgRP was also significant predictor of WASO% (ß = 0.452 and p < 0.05). CONCLUSIONS Active CD carries an increased risk of impaired sleep efficiency and continuity which may worsen health-related quality of life. Elevated circulating AgRP and, to a lesser extent, leptin may be associated with decreased sleep efficiency and continuity in patients with CD. Patients with CD who have subjective sleep symptoms should be screened with polysomnography.

Abstract
INTRODUCTION National data on asthma characteristics and the factors associated with uncontrolled asthma seem to be necessary for every country. For this purpose, we developed the Turkish Adult Asthma Registry for patients with asthma aiming to take a snapshot of our patients, thereby assigning the unmet needs and niche areas of intervention. METHODS Case entries were performed between March 2018 and March 2022. A web-based application was used to record data. Study outcomes were demographic features, disease characteristics, asthma control levels, and phenotypes. RESULTS The registry included 2053 patients from 36 study centers in Turkey. Female subjects dominated the group (n = 1535, 74.8%). The majority of the patients had allergic (n = 1158, 65.3%) and eosinophilic (n = 1174, 57.2%) asthma. Six hundred nineteen (32.2%) of the patients had obese asthma. Severe asthma existed in 670 (32.6%) patients. Majority of cases were on step 3-5 treatment (n: 1525; 88.1%). Uncontrolled asthma was associated with low educational level, severe asthma attacks in the last year, low FEV1, existence of chronic rhinosinusitis and living in particular regions. CONCLUSION The picture of this registry showed a dominancy of middle-aged obese women with moderate-to-severe asthma. We also determined particular strategic targets such as low educational level, severe asthma attacks, low FEV1, and chronic rhinosinusitis to decrease uncontrolled asthma in our country. Moreover, some regional strategies may also be needed as uncontrolled asthma is higher in certain regions. We believe that these data will guide authorities to reestablish national asthma programs to improve asthma service delivery.

Abstract
OBJECTIVES The purpose of this study was to investigate the effectiveness of Kinesio® tape application associated to exercise in patients with obstetric brachial plexus injury (OBPI). MATERIALS AND METHODS Ninety patients with Erb-Duchenne palsy secondary to OBPI participated in a 3-month study, in 2 groups; study group (n = 50) and control group (n = 40). Both followed the same physical therapy program, while the study group also received Kinesio® taping over the scapula and forearm. The patients were evaluated, pre- and post-treatment, using the Modified Mallet Classification (MMC), Active Movement Scale (AMS), and active range of motion (ROM) of the plegic side. RESULTS There were no statistically significant intergroup differences in age, gender, birth weight or plegic side (p > 0.05), or in pre-treatment MMC and AMS scores (p > 0.05). There were significant differences in favor of the study group for Mallet 2 (external rotation) (p = 0.012), Mallet 3 (hand on the back of the neck) (p < 0.001), Mallet 4 (hand on the back) (p = 0.001) and total Mallet score (p = 0.025), and for AMS shoulder flexion (p = 0.004) and elbow flexion (p < 0.001). ROM results before and after treatment (within groups) showed significant improvement in both groups (p < 0.001). CONCLUSION Since this a was a preliminary study, the results should be interpreted with caution in terms of clinical efficacy. The results suggest that associating Kinesio® taping to conventional treatment helps functional development in patients with OBPI.'

Abstract
Background: Aspirin treatment after desensitization (ATAD) is effective in preventing nasal polyps recurrence as well as respiratory symptoms in patients with nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory diseases (N-ERD). However, there is no consensus on effective daily maintenance doses in ATAD. Therefore, we aimed to compare the effects of two different maintenance doses of aspirin on clinical outcomes for 1-3 years of ATAD. Methods: This was a retrospective, multicenter study that involved four tertiary centers. The maintenance doses of daily aspirin were 300 mg in one center and 600 mg in the remaining three. The data of patients who were on ATAD for 1-3 years were included. Study outcomes (nasal surgeries, sinusitis, asthma attacks, hospitalization, oral corticosteroid use, and medication uses) were assessed in a standardized way and recorded from case files. Results: The study initially included 125 subjects, 38 and 87 were receiving 300 and 600 mg daily aspirin for ATAD, respectively. Number of nasal polyp surgeries decreased after 1 -3 years compared with before ATAD in both groups (group 1, baseline: 0.44 ± 0.07 versus first year: 0.08 ± 0.05; p < 0.001 and baseline: 0.44 ± 0.07 versus 3rd year: 0.01 ± 0.01; p < 0.001; and group 2, baseline 0.42 ± 0.03 versus first year: 0.02 ± 0.02; p < 0.001 and baseline: 0.42 ± 0.03 versus 3rd year: 0.07 ± 0.03; p < 0.001). Conclusion: Given the comparable effects of 300 mg and 600 mg aspirin daily as maintenance treatment of ATAD on both asthma and sinonasal outcomes in N-ERD, our results suggest using 300 mg of aspirin daily in ATAD owing to its better safety profile.

Abstract
OBJECTIVES The objectives of this study were to evaluate and compare the test-retest reliability of acoustic parameters (jitter [%], shimmer [%], noise-to-harmonic ratio (NHR), and voice turbulence index (VTI)) by using multidimensional voice program (MDVP), and to detect the discriminatory power of the acoustic measures with respect to dysphonic voices and normal voices. DESIGN, SETTING, PARTICIPANTS, AND METHODS Fifty-four (25 male and 29 female) participants with voice disorders and fifty-one (27 male and 24 female) participants with normal voices were enrolled in this study. They were assessed by anamnesis, visual examination, auditory perceptual assessment (GRBAS), and acoustic measurements. The intraclass correlation coefficient was used to determine the test-retest reliability. The effect size (d value) and p value obtained from the t-test were used to determine the discriminatory power. RESULTS In the normal group, good reliability was observed for jitter, shimmer, and NHR, and moderate reliability was observed for VTI. With regard to the dysphonic group, jitter, shimmer, and VTI were moderately reliable, and the NHR had good reliability. Meanwhile, the discriminatory powers of jitter and shimmer were evaluated as 'medium', and those of NHR and VTI as 'small'. CONCLUSIONS The reliability and discriminatory powers of our acoustic measures were high compared with most other studies. Their level of reliability and discriminatory power can be maximised by using stringent rules. However, attaining an excellent level of reliability and discriminatory seems infeasible power owing to the variable characteristic of voice. Therefore, acoustic measures should be adopted as a complementary tool.

Abstract
OBJECTIVE Cardiovascular diseases are responsible for the majority of deaths on a global scale. Atherosclerosis is the main risk factor for cardiovascular disorders and represents a complex phenomenon associated with endothelial dysfunction and inflammation. Statins, especially atorvastatin (ATV) and pitavastatin (PTV), are common agents used to control ongoing atherosclerotic events in the body to minimize cardiovascular disease-based deaths. MATERIALS AND METHODS The present study aimed at comparing the efficacy of ATV and PTV in a cell line model of inflammation. Human saphenous vein cells were treated with TNF-alpha to mimic atherosclerotic conditions, and the cells were divided into 7 groups, including control, DMSO, TNF-alpha (10 ng/mL-6 hours), ATV (50 μM/24 hours), PTV (2 μM/24 hours), ATV (50 μM/24 hours)+TNF-alpha (10 ng/mL-6 hours) and PTV (2 μM/24 hours)+TNF-alpha (10 ng/mL-6 hours). The expression levels of 20 proinflammatory cytokines and chemokines were investigated in these groups using a human atherosclerosis antibody array. RESULTS Possible pathway interactions were determined by STRING and PANTHER analyses. Comparison with the effect of ATV indicated that PTV reduced the levels of 4 proinflammatory cytokines: CCL11, CSF2, CCL20, and TGFB1 (p<0.05). CONCLUSIONS Pleiotropic effects of pitavastatin against cardiovascular diseases appeared to be better; however, additional studies are required to compare statins and to identify new drugs that maintain broader protection from the risks of cardiovascular diseases.

Abstract
Radiotherapy can be employed as a therapeutic modality alone in the early stages of cancer and is used together with other treatments such as surgery and chemotherapy in more advanced stages. However, exposure to ionizing radiation in association with radiotherapy affects several organs in the head and neck and can give rise to early and late side effects. Exposure to ionizing radiation used in radiotherapy is known to cause cell damage by leading to oxygen stress through the production of free oxygen radicals (such as superoxide radicals, hydroxyl radical, hydrogen peroxide, and singlet oxygen), depending on the total radiation dosage, the fractionation rate, radiosensitivity, and linear energy transfer. The purpose of the present study was to determine the potential protective role of a powerful and highly selective α2-adrenoreceptor agonist with a broad pharmacological spectrum against salivary gland damage induced by ionizing radiation exposure. Forty Sprague-Dawley rats were divided into five groups-control, ionizing radiation, ionizing radiation + dexmedetomidine (100 µg/kg), ionizing radiation + dexmedetomidine (200 µg/kg), and ionizing radiation + amifostine (200 mg/kg). Following exposure to ionizing radiation, we observed necrosis, fibrosis, and vascular congestions in parotid gland epithelial cells. We also observed increases in malondialdehyde (MDA) and cleaved Caspase-3 levels and a decrease in glutathione (GSH). In groups receiving dexmedetomidine, we observed necrotic epithelial cells, fibrosis and vascular congestion in parotid gland tissue, a decrease in MDA levels, and an increase in GSH. Dexmedetomidine may be a promising antioxidant agent for the prevention of oxidative damage following radiation exposure.

Abstract
BACKGROUND Promising studies have been conducted with many substances to reduce the ototoxic effects of cisplatin, but there is no treatment that completely eliminates the ototoxic effect. OBJECTIVES To determine the effectiveness of astaxanthin (ASX) as a protective agent against cisplatin-induced ototoxicity. MATERIAL AND METHODS Thirty-six rats were randomly divided into 6 groups. Group 1 received no drug injections except for anesthetics; group 2 received intraperitoneal (IP) olive oil only for 8 days; group 3 received only IP ASX 75 mg/kg dissolved in olive oil for 8 days; group 4 received a single dose of only IP 16 mg/kg cisplatin on the 5th day; group 5 received 25 mg/kg ASX IP daily for 8 days and a single 16 mg/kg dose of cisplatin on the 5th day; group 6 received 75 mg/kg ASX IP daily for 8 days and a single 16 mg/kg dose of cisplatin on the 5th day. The animals were tested for distortion product otoacoustic emissions (DPOAE) before and 3 days after cisplatin treatment. The animals in all groups were sacrificed under anesthesia on the 10th day. Before sacrifice, inferior vena cava blood samples were drawn into commercial tubes for biochemical analysis and their cochlea were prepared for histological analysis. RESULTS The ASX+cisplatin groups demonstrated significantly higher DPOAE thresholds when compared to the cisplatin-only group (p < 0.05). The ASX 25 mg/kg/day+cisplatin group showed a significant increase in total antioxidant capacity compared to the cisplatin-only group, whereas the ASX 75 mg/kg/day+cisplatin group had significantly lower total oxidative stress and oxidative stress index. Histologic results showed that the cortical organ was better preserved in the ASX+cisplatin groups compared to the cisplatin-only group, and the degeneration in the spiral ganglion and inner and outer hair cells was less visible in the ASX groups. CONCLUSIONS Astaxanthin can protect hearing from cisplatin-induced ototoxicity, prevent cellular degeneration and significantly reduce oxidative stress.

Abstract
PURPOSE While the use of cartilage graft for revision tympanoplasty is quite common, the data on the revision of cartilage tympanoplasty are limited. Our study aims to present the results of our patients who underwent endoscopic butterfly inlay myringoplasty for the revision of cartilage tympanoplasty. METHODS Demographic data, ear sides, perforation locations, graft success rates and hearing results of the patients who underwent endoscopic butterfly inlay myringoplasty for revision of cartilage tympanoplasty between Sep 2017 and Jan 2020 were evaluated. RESULTS A total of 17 patients with 7 (41%) females and 10 (59%) males were included in our study. Eight of the ears (47%) were right and nine (53%) were left. Perforation locations included ten (59%) anterior, six (35%) inferior, and one (6%) posterior. The graft success rate of our study was 100%. No changes were observed in post-operative air conduction, bone conduction and air-bone gap values compared to the pre-operative period (p > 0.05). CONCLUSIONS Endoscopic butterfly inlay myringoplasty for the revision of cartilage tympanoplasty is considered to be a safe surgical technique with satisfactory anatomical and hearing results.

Abstract
BACKGROUND New generation Doppler ultrasonography (DUSG) application effects on cochlea and cochlear nucleus (CN) are unclear. We aimed to investigate the effects of new generation DUSG application at different frequencies in prenatal period on cochlea and CN in rats. OBJECTIVE Twenty-four pregnant female rats were divided into three groups (n = 8). Group 1 was the control group and was not subjected to any treatment. Group 2 was determined as the USG every day (USGED) treatment group. Group 2 has received DUSG application every day from the 4th to 18th day (20 min/15 per day). Group 3 has received DUSG application as "2 days/one dose as every other day application" (USG2D1) from the 4th to 18th day (20 min/8 every other day). Twenty-four female rats were sacrificed in 21 days. Also, 24 pups were sacrificed after two days. First day after born, the cochlear activities of the right ears of all pups were examined using DPOAEs. Second day, neural tissues from CN were evaluated histopathologically and immunohistochemically. RESULTS There was no any statistical difference between the groups in respect of histopathologically. USGED group showed mild caspase-3 positive neurons and glial cells. However, there was no significant difference between the USGED and other groups (p>.05). Similarly, the rats applied with USG2D1 had mild caspase-3 expression, but no significant difference between the USG2D1 and other groups (p>.05). Differences in DPOAE amplitudes, and therefore in cochlear activity, between the groups were revealed. The decrease in cochlear activity between the groups involved frequencies at 2, 8, 16, and 32 kHz (p<.05). CONCLUSIONS Multiple administration of new generation DUSG to pregnant rats has not shown harmful effects on the cochlear neural tissue. High frequencies are more sensitive in cochlea to apply DUSG.

Abstract
PURPOSE The aim of the present study was to evaluate the prognostic factors that may affect the success in endoscopic cartilage tympanoplasty and determine the outcomes of endoscopic cartilage tympanoplasty. METHODS This study included 312 patients who underwent transcanal endoscopic type I cartilage tympanoplasty. The effects of sex, the affected side, the size of the perforation, the location of the perforation, the absence of myringosclerosis, external ear canal protrusion, the condition of the contralateral ear, and surgical experience on the rate of graft success and hearing improvement were investigated. RESULTS The affected side, sex, location of the perforation, myringosclerosis, the condition of contralateral ear, and surgical experience did not significantly affect the surgical success (p > 0.05). However, the size of perforation and ear canal wall protrusion were significantly related to both functional and anatomical success (p < 0.05). CONCLUSION Endoscopic transcanal type I cartilage tympanoplasty can be performed with a high anatomical and functional success rate. However, surgeons should be more careful and design a case-specific operation strategy in patients with external ear canal anterior wall protrusion and large perforations.

Abstract
OBJECTIVES Endoscopic type 1 tympanoplasty using cartilage grafts for repair of chronic tympanic membrane perforation is increasing. The aim of this study was to evaluate the results of endoscopic type 1 cartilage tympanoplasty in children. MATERIALS AND METHODS Patients under 18 years of age who underwent type 1 cartilage tympanoplasty between January 2013 and February 2019 were retrospectively evaluated. Anatomic success rate was calculated according to the intact status of the graft. Air conduction (AC), bone conduction (BC), air-bone gap (ABG) and hearing gain were calculated using pure tone audiometry tests at pre-operative, and 6th month postoperative period. Patients with postoperative ABG ≤20 dB were considered as functionally successful. RESULTS The study included 56 patients (6 bilateral) and 62 ears. The anatomic success rate of our study was 91.9% (57/62). Preoperative AC was 36.4 ± 6.5 (21-50) dB, BC was 7.8 ± 3.7 (5-25) dB, and ABG was 28.6 ± 6.9 (10-41) dB. Postoperative AC was 24.5 ± 8.8 (7-45) dB, BC was 7.6 ± 3.4 (5-19) dB, and ABG was 16.9 ± 7.4 (2-32) dB. There was no change in postoperative BC (p: 0.683), whereas AC, and ABG significantly decreased (p < 0.001). Mean hearing gain was 12.1 ± 6.2 (3-26) dB and the functional success rate was 72.5% (45/62). CONCLUSION Endoscopic type 1 cartilage tympanoplasty, a minimally invasive surgical procedure, provided successful functional and anatomical results at the pediatric population.

Abstract
PURPOSE Although bilateral same-day tympanoplasty is a faster and more comfortable procedure for patients, it is rarely performed due to its theoretical risks. The present study aims to evaluate the results of patients who underwent bilateral same-day endoscopic tympanoplasty. MATERIALS AND METHODS In this study, 26 patients and 52 ears were evaluated. Postoperative anatomic success rate, pre- and postoperative hearing test results, hearing gains and postoperative complications were recorded. RESULTS Postoperative anatomic success rate was 92.3% (48/52). Audiological tests revealed the preoperative air-bone gap (ABG) as 19.1 ± 8.8 (7-35) dB and postoperative ABG as 9.8 ± 5.7 (5-25) dB. Postoperative ABG decreased significantly (p: <0.001) and 9.2 ± 4.6 (2-23) dB hearing gain was obtained. We did not observe any significant complications. CONCLUSION Bilateral same-day endoscopic tympanoplasty is a feasible surgical procedure with good anatomic and functional outcomes, low complication rate and good postoperative patient comfort.

Abstract
PURPOSE Bleeding is one of the most challenging issues for surgeons performing endoscopic stapedotomy. During creation and elevation of the tympanomeatal flap (TMF) prevention or control of bleeding greatly facilitates the safety and comfort in the next steps of the surgery. The aim of this study was to compare the effects of cautery versus cold instrumentation during creation of TMF at endoscopic stapedotomy surgery. METHODS We investigated 15 patients TMF created with cautery and 14 patients with cold instrument, and compared bleeding scores, operation time, postoperative hearing, pain and complications between groups. RESULTS The mean bleeding score was significantly lower in cautery incised patients compared to cold instrument patients (1.2 ± 0.9 vs. 2.3 ± 1, p = 0.005). Mean duration of surgery was also significantly shorter in cautery used patients (35.3 ± 6.8 vs. 48.8 ± 9.2 min, p < 0.001). There was no significant difference between postoperative pain, complications, wound healing, and auditory outcomes. CONCLUSIONS Cautery may be a better choice for the creation of TMF in endoscopic stapedotomy surgery due to reduced bleeding, shorter operation time and increased comfort without causing any complications.

Abstract
Background: Total ossicular chain reconstructions are performed to connect mobile stapes footplate and tympanic membrane. Data on the use of incus for total ossicular reconstruction is quite limited in the literature. Objective: The main objective of this study is to describe a novel surgical method that utilizes incus with bone cement to stabilize the ossicular chain for total ossicular reconstruction. Materials and methods: 16 patients who underwent total ossicular reconstruction using our method were included in this study. We evaluated hearing by comparing preoperative and postoperative air-bone gap (ABG), air conduction (AC) and bone conduction (BC). The percentage of patients achieving ABG ≤20 dB was determined. Results: The mean preoperative ABG was 35.3 ± 8.2 and postoperative ABG decreased significantly to 23.7 ± 7.6 (p < .001). The mean preoperative AC (57.5 ± 10) decreased significantly postoperatively to (46.5 ± 13.3)(p = .014). There was not any difference between pre- and post-operative BC. We achieved successful hearing results (ABG ≤ 20dB) in 44% of patients. Conclusion: The use of incus with bone cement stabilization for total ossicular reconstruction seems a feasible option. Good hearing outcomes, and low cost, complication, and extrusion rate may be the main reasons to prefer this method.

Abstract
The main aim of our study is to evaluate whether the effect of smoking on the auditory system shows gender differences. Another aim is to evaluate whether smoking has any influence on the absorbance of sound. There were 236 volunteers including 90 nonsmokers (42 females and 48 males) and 146 smokers (72 females and 74 males) in the study. Smokers were grouped according to pack-years of smoking as 5 to 10 pack-years, 11 to 20 pack-years, and more than 20 pack-years. Pure tone audiometry and wideband tympanometry were performed in all individuals. Both female and male smokers who consume more than 20 pack-years had significantly higher hearing thresholds at 4 and 6 kHz and significantly lower sound energy absorbance rates at 4, 6, and 8 kHz. Moreover, female smokers with a consumption of 11 to 20 pack-years had significantly higher hearing thresholds at 6 kHz and significantly lower sound energy absorbance rates at 6 and 8 kHz. Smoking causes hearing loss at high frequencies in both females and males, especially in a dose-dependent manner affecting individuals with a consumption of more than 20 pack-years. The sound energy absorbance is significantly reduced at 4, 6, and 8 kHz. In addition, these effects may occur in women with even less exposure.

Abstract
The aim of our study was to obtain wideband tympanometry (WBT) findings in Meniere's disease (MD). It also aimed to evaluate whether the data obtained have diagnostic significance. 21 patients who were followed-up for unilateral Meniere's Disease were evaluated. The ears with Meniere disease were grouped as the MD group and the opposite ears were grouped as the control group. WBT results were recorded as resonance frequency (RF) and frequency-specific absorbance values at 10 different frequencies in the 0.25-8.0 kHz range. Statistical analysis was performed with t test and receiver-operating characteristic analysis. Considering the WBT results, RF was significantly lower in the MD group compared to the control group (p < 0.001). Frequency-specific absorbance values at 0.25, 0.5, 0.75 and 1 kHz were significantly lower in the MD group compared to the control group (p < 0.05). No significant difference was found at 1.5 kHz and above (p > 0.05). For the MD, the RF below 598 Hz was 85.7% sensitive and 76.2% specific, the absorbance at 0.25 kHz below 8% was 66.7% sensitive and 61.9% specific, the absorbance below 17% at 0.5 kHz was 71.4% sensitive and 62.1% specific, the absorbance below 36% at 0.75 kHz was 81% sensitive and 57.8% specific, and the absorbance below 46% at 1 kHz was 71.5% sensitive and 66.7% specific. When MD was compared with intact ears, it was observed that RF was lower, and absorbance decreased in low frequencies. These data is statistically significant, but the sensitivity level is not enough for diagnostic use. Therefore, it is considered as an complementary test for the diagnosis.

Abstract
Purpose: We investigated the radioprotective effect of endogenous melatonin release at different times associated with the circadian rhythm on head and neck radiotherapy. Materials and methods: Two groups of animals were subjected daily to 8 Gy single fraction radiotherapy in the head and neck region from 5:00 to 6:00 (the morning group) or from 19:00 to 20:00 (the evening group). Corresponding untreated groups served as controls. Submandibular glands from rats sacrificed on the seventh day after irradiation were assessed biochemically and histopathologically. Melatonin, malondialdehyde and superoxide dismutase levels in blood collected immediately prior to irradiation were measured with rat-specific ELISA kits. Results: In irradiated rats, melatonin, malondialdehyde and superoxide dismutase levels were significantly higher in the evening group than in the morning group. In nonirradiated rats, melatonin and superoxide dismutase levels were significantly higher in the evening group than in the morning group. The areas of seromucous acinar cells were similar between the irradiated and nonirradiated evening groups, but the area was higher in the evening irradiated group than in the morning irradiated group. Conclusion: Consideration of endogenous melatonin secretion associated with the circadian rhythm may offer new therapeutic solutions for the complications of head and neck radiotherapy.

Abstract
Radiotherapy is a method of treatment used on malignant head and neck tumors; however, it may lead to adverse effects by influencing other tissues because its effects are not specific to tumor tissues. These adverse effects limit the effectiveness of the treatment and sometimes lead to termination of the treatment. This study aims to histopathologically and biochemically investigate the protective effect of whortleberry against the cellular degeneration and oxidative stress that take place in salivary glands due to radiotherapy. The rats were divided into 6 groups. One group was given radiotherapy only, one group was given radiotherapy and 100 mg/kg of whortleberry, and one group was given radiotherapy and 200 mg/kg of whortleberry. The remaining 3 groups were designated as whortleberry, sham, and control groups. At the end of the study, samples collected were histopathologically and biochemically analyzed. In the group given radiotherapy only, acinar areas were reduced histopathologically, whereas ductal areas increased (P < .01). Oxidative stress increased only in the group given radiotherapy, whereas the oxidative stress levels in the other groups were close to those in the control groups. In conclusion, whortleberry reduces cellular degeneration and oxidative stress that take place in salivary glands due to radiotherapy.

Abstract
BACKGROUND This case report describes the complete full-mouth treatment of hypocalcified amelogenesis imperfecta (AI) by chairside computer-aided design and computer-aided manufacturing (CAD/CAM). CASE SUMMARY After several years of interrupted dental care, a 17-year-old female patient presented with pain and also esthetic and functional discomfort. With loss of enamel and dyschromia affecting all teeth, the diagnosis was hypocalcified AI. Affected tissues were eliminated, gingivectomy with laser was performed, an indented jig was used to record the centric relationship during optical impressions, and 28 full ceramic crowns were created by chairside CAD/CAM in four sessions. The patient reported rapid pain relief and an overall improvement of well-being. CONCLUSION AI sequelae can be treated promptly and conservatively with chairside CAD/CAM, obtaining esthetic and functional results.

Abstract
Objective The aim of this study was to analyse the effects of minimal-and high-flow anaesthesia on cerebral oxygenation during septorhinoplasty with controlled hypotension using near-infrared spectroscopy. Methods Eighty patients scheduled for septorhinoplasty under general anaesthesia with controlled hypotension were randomised into two groups: minimal-flow (MF) or high-flow (HF). Both groups received desflurane anaesthesia to maintain bispectral index values at 40%-50% and 0.25-0.5 μg kg-1 min-1 i.v. remifentanyl infusion to maintain mean arterial blood pressure between 55 and 65 mmHg. The MF group received 5 L min-1 of fresh gas flow for the first 10 mins then the gas flow was reduced 0.4 L min-1. The HF group received 2 L min-1 of fresh gas flow throughout. Haemodynamic parameters and cerebral oxygen saturation were measured. Results There were no statistical differences in demographic variables, duration of anaesthesia and surgery, time to extubation and proceeding to an Aldrete score of 9. There were no statistical differences in haemodynamic parameters, end-tidal CO2 and cerebral oxygen saturation. The amount of desflurane used in the MF group was significantly lower than that used in the HF group (30.5±9.8 mL vs. 48.5±12.1 mL; p<0.05). Conclusion MF and HF anaesthesia did not lead to any difference in cerebral oxygen saturation in patients undergoing septorhinoplasty with controlled hypotension. MF anaesthesia may thus be used as safely as HF anaesthesia is.

Abstract
OBJECTIVES We explored whether wideband tympanometry (WBT) could be used as a screening test for superior semicircular canal dehiscence (SSCD), and obtained new WBT data (given that the test is not yet in common clinical use) on patients with SSCD. METHODS We compared the WBT data of patients clinically and radiologically diagnosed with SSCD in our hospital between 2013 and 2018 to those of healthy volunteers. We compared the resonance frequency (RF), maximum absorbance frequency (MAF), and maximum absorbance ratio (MAR). The t-test was used for statistical analysis with the significance level set to P<0.05. In addition, we used receiver operating characteristic analysis to derive cutoff values for SSCD diagnosis in terms of sensitivity and specificity. RESULTS Seventeen patients (four with bilateral and 13 with unilateral disease; 17 ears) diagnosed with SSCD and 27 healthy volunteers (47 ears) were included. The mean RFs of the SSCD patients and healthy subjects were 548.7 Hz (range, 243 to 853 Hz) and 935.1 Hz (range, 239 to 1,875 Hz), respectively (P<0.001). The mean MARs of the SSCD patients and healthy subjects were 89.4% (range, 62% to 100%) and 82.4% (range, 63% to 99%), respectively (P=0.005). The mean MAFs of the SSCD patients and healthy subjects were 1,706.3 Hz (range, 613 to 3,816 Hz) and 2,668 Hz (range, 876 to 4,387 Hz), respectively (P<0.001). In terms of SSCD diagnosis, a MAR above 86% afforded 81% sensitivity and 77% specificity; an RF below 728 Hz, 86% sensitivity and 81% specificity; and an MAF below 1,835 Hz, 79% sensitivity and 67% specificity. CONCLUSION WBT may be a useful clinical screening test for SSCD. The RF and MAF were lower, and the MAR higher, in SSCD patients than in normal controls.

Abstract
Objective Controlled hypotension is commonly induced during functional endoscopic sinus surgery to limit mucosal bleeding. This may be detrimental to elderly patients and patients with arterial stenosis. The aim of this pilot study was to determine if a normotensive anaesthetic technique with sufficient analgesia and without profound vasodilation may reduce intraoperative bleeding and incidence of adverse haemodynamic effects associated with vasodilation and variable rate continuous infusions. Methods In this double-blind randomised controlled trial in a tertiary care centre, a total of 88 patients were randomised to receive intravenously either 0.1 mg kg-1 metoprolol and 1 mg kg-1 tramadol following anaesthesia induction (MT group) or a bolus dose of 0.5 μg kg-1 remifentanil following anaesthesia induction, followed by 0.25-0.5 μg kg-1 min-1 remifentanil infusion (R group). The primary outcome was quality of surgical field and incidence of adverse haemodynamic effects. The secondary outcomes were time to achieve intraoperative bleeding score <3, bleeding rate and changes in cerebral regional oximetry. Results A total of 105 patients were recruited, in which 88 were randomised. The median intraoperative bleeding score was similar (1, interquartile range: 1-1, p=0.69). The mean bleeding rate was lower in the MT group, although the difference was not significant (p=0.052, 95% CI 0 to 8.8). Hypotension, bradycardia and cerebral desaturation in the MT group were not observed compared to hypotension in 3 (7%), bradycardia in 18 (41%) and cerebral desaturation in 2 (5%) patients in the R group (p=0.241, p<0.001, p=0.474, respectively). Conclusion Providing sufficient analgesia and eliminating stress response can provide stable heart rate and good surgical field with no need for additional hypotension. This normotensive technique may be useful in patients with stenotic arteries or ischaemic organ diseases.

Abstract
PURPOSE To evaluate the course of lower cranial nerves (CNs) within the neck in relation to surrounding structures and anatomic landmarks via a cadaveric dissection study. METHODS A total of 70 neck dissections (31 bilateral, 8 unilateral) were performed on 39 adult fresh cadavers [mean (SD) age: 38.5 (11.2) years, 29 male, 10 female] to identify the course of lower CNs [spinal accessory nerve (SAN), vagus nerve and hypoglossal nerve] within the neck in relation to surrounding structures [internal jugular vein (IJV), common carotid artery (CCA)] and distance to anatomical landmarks (cricoid cartilage, hyoid bone, digastric muscle). RESULTS SAN travelled most commonly anterior to IJV (51.4%) at the level of jugular foramen, while travelling lateral to IJV at the post belly of digastric (55.7%) and inferior to digastric muscle (90%) in most neck dissections. Vagus nerve travelled lateral to CCA in majority (94.3%) of dissections, while medial (2.9%), posterolateral (1.4%) and posterior (1.4%) positions were also noted. Average distance of hypoglossal nerve was 27.7 (9.7) mm to carotid bifurcation, 9.3 (3.9) mm to hyoid bone, and 54.7 (18.0) mm to the inferior border of cricoid cartilage. CONCLUSION In conclusion, our findings indicate that anatomic variations are not rare in the course of lower CNs within the neck in relation to adjacent structures, and awareness of these variations together with knowledge of distance to certain anatomic landmarks may help the surgeon to identify lower CNs during neck surgery and prevent potential nerve injuries.

Abstract
Introduction the otological evaluation is highly significant in those branches of medicine in which the general evaluation of the patient is conducted by general practitioners and pediatricians. Objectives To investigate the otologic findings and their incidences in the sample, which consisted of patients who presented to the pediatric outpatient clinic with non-otologic complaints. Methods Patients, aged between 2 and 16 years, who had neither otorhinolaryngological complaints nor history of surgery by the otolaryngology (ear, nose and throat, ENT) department were included in the present study. The findings detected in the external auditory system and in the tympanic membranes as well as the otorhinolaryngologists' otologic examination findings of the referred patients were recorded from the files of each patient along with the applied medical and surgical treatments, and diagnostic investigations. Results Of a total of 973 patients evaluated, 129 (13.2%) were referred to the ENT outpatient clinic due to any otologic pathology. In the otorhinolaryngological examinations, false positivity was detected in 12 (1.2%) patients, and pathological findings were detected in 117 (12%) patients who received the following diagnoses: 68 (6.9%) had otitis media with effusion(OME); 37 (3.8%) had cerumen impactions; 8 (0.8%) had acute otitis media (AOM); 2 (0.2%) had ticks in the external auditory canal; 2 (0.2%) had a retraction pocket in tympanic membrane; 1 (0.1%) had unilateral central dry perforation of the tympanic membrane; and 1(0.1%) had congenital cholesteatoma. Conclusion Any complications and sequelae that may develop due to any pathologies and predominantly infections can be prevented by an early diagnosis, which can be made by means of a simple examination, performed merely with an otoscope. Pediatricians and general practitioners should be in close contact with otorhinolaryngologists regarding the pathologies they identify.

Abstract
Background The purpose of this study was to reveal the role of septoplasty in curing chronic rhinosinusitis (CRS) in patients with significant septal deviation. Methods This prospective study involved 26 patients with CRS and septal deviation. The patients were randomly divided into two groups according to the applied surgical procedures. In the first and second groups, septoplasty and septoplasty plus endoscopic sinus surgery were applied, respectively. Subjective (questionnaire) and objective (endoscopy and computerized tomography) success rates were used to analyze the results. Results Septoplasty alone and septoplasty plus endoscopic sinus surgery were applied in 57.7% (15/26) and 42.3% (11/ 26) of the patients, respectively. Success rates were 93.3% (14/15) and 81.8% (9/11), subjectively (p > 0.05), and 66.7% (10/15) and 54.5% (6/11), objectively (p > 0.05), respectively in each group. Conclusion We suggest that septoplasty alone can be adequate for the treatment of CRS with septal deviation.

Abstract
AIM The aim of this prospective animal study is to investigate the influence of multiple administrations of macrocyclic ionic (gadoteric acid) and linear nonionic (gadodiamide) gadolinium-based contrast agents (GBCA) on submandibular gland tissue (SGT) of the rats. MATERIAL AND METHOD Twenty-four Sprague Dawley female rats were included the study. Group 1 was determined as a control group (n = 6). Group 2 was determined as saline group (n = 6). Group 3 was determined as Omniscan group (n = 6) and received only intraperitoneal (IP) 0.1 mmol (0.2 mL/kg)/kg gadodiamide for 8 days. Group 4 was determined as Dotarem group (n = 6) and received only IP 0.1 mmol (0.2 mL/kg)/mg/kg gadoteric acid daily for 8 days. On the 9th day of the administration, the rats were sedated with ketamine and xylazine through IP injection. The right SGT was removed after sedation. Histopathological and immunohistochemical changes in SGT were evaluated. RESULTS The SGT of the Omniscan and Dotarem groups decreased SGT acini surface area, and serous acinar cells number were observed. On the other hand, no pathology was observed. Mucous acinar cells' caspase-3 positivity for the same markers in Omniscan and Dotarem sections was similar to the control group. However, Omniscan and Dotarem groups serous acinar cells were caspase-3 (+) staining. The intensity of serous acinar cells' caspase-3 (+) for the same markers in Dotarem sections was similar to the Omniscan group. The results also revealed in the analysis of the mean area of the acinus area of the SGT; there were significantly decreased Dotarem group rats when compared to control rats (p < 0.05). CONCLUSION We consider that numerical increased apoptosis results arise from repeated doses of GBCAs. Being aware of this effect of the contrast agent may have significance for the chronic sialo-adenitis patients group when used for recurrent contrasted MRI for diagnosis of diseases like MS which requires in follow-up. We should be aware about the frequently contrasted MRI in routine investigations.

Abstract
OBJECTIVE Mucociliary transport (MCT) is an important defense mechanism of the respiratory tract. One of the major factors determining MCT is the ciliary activity of the respiratory epithelium. Rhinoscintigraphy is the most commonly used method for the analysis of mucociliary activity. The aim of this study was to investigate the effect of facial paralysis on the nasal mucociliary clearance. MATERIALS AND METHODS This study included 38 Bell's palsy patients as the study group and 10 subjects without any history of paranasal sinus disease or facial paralysis as the control group. A drop of technetium 99m-labeled macroaggregated albumin (Tc-99m MAA) was placed posterior to the head of the inferior turbinate and followed with a gamma camera. MCT rate was measured as the velocity of Tc-99m MAA drop. RESULTS The mean MCT rate was 4.27 ± 0.76 millimeters per minute (mm/min) on 20 sides of 10 healthy controls, 4.11 ± 2.91 mm/min on the affected sides of the patients with Bell's palsy, and 6.03 ± 3.13 mm/min on the nonparalyzed sides of the patients. MCT rate was statistically significantly faster in the nonparalyzed side when compared to the paralyzed side in Bell's palsy patients (P = 0.001). MCT rates were not significantly different in the control group and paralyzed sides of the Bell's palsy patients (P = 0.810). The MCT rate was statistically significantly faster in the nonparalyzed sides of Bell's palsy patients when compared to the controls (P = 0.017). CONCLUSION This study showed a faster MCT rate on the nonparalyzed side in Bell's palsy patients when compared to the paralyzed side and the control subjects. A compensatory mechanism could be the underlying reason for faster MCT on the nonparalyzed side. Further studies on larger patient groups are needed to investigate the effect of facial paralysis on the MCT and changes of facial nerve function on the opposite, nonparalyzed side of the face.

Abstract
PURPOSE To investigate the effect of posterior ocular hemodynamics on the retinal nerve fiber layer (RNFL), choroid thickness (CT) and central macular thickness (CMT) in patients with obstructive sleep apnea syndrome (OSAS) and to reveal the association with glaucomatous optic neuropathy. METHODS The research was planned as a prospective, randomized study. The ophthalmic, retinal and posterior ciliary artery pulsatile index (PI) and resistive index (RI) were measured by colored Doppler sonography. RNFL thickness, CMT and CT were then measured by spectral-domain optical coherence tomography. RESULTS Sixty subjects were divided into four groups-mild, moderate and severe OSAS and a control group. There were 16 subjects in the control group, 14 in the mild OSAS group, 15 in the moderate OSAS group and 15 in the severe OSAS group. Ophthalmic artery and central retinal artery PI and RI values of the OSAS patients did not show statistically significant difference than those of the control group, but posterior ciliary artery (PCA) PI and RI values were significantly higher. In addition, mean, superior and inferior RNFL thickness values were significantly lower than those in the control group. Moreover, the glaucoma prevalence of the OSAS patients in this study was 6.8% and all of these patients were in the severe OSAS group. CONCLUSION PI and RI values of the PCA, which supplies the optic nerve, show a linear increase as the apnea hypoxia index values in OSAS. As the grade of OSAS improves, this situation leads to a more serious ischemic optic neuropathy. Furthermore, the prevalence of glaucoma in this study is found to be higher in the severe OSAS group.

Abstract
OBJECTIVE Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease. Via autoimmune mediators, AS can damage the auditory system similar to other systems. Otoacoustic emission studies in AS patients showed that the damage that causes hearing loss was in the outer hair cells. The medial olivocochlear (MOC) reflex is used to evaluate the MOC efferent system (MOES), which includes the outer hair cells. The aim of this study was to evaluate the presence of subclinical damage in the inner ear with the aid of the MOC reflex test in AS patients with no hearing complaints. PATIENTS AND METHODS Thirty-four patients with AS and a control group of 30 healthy volunteers with similar demographic characteristics were evaluated in the study. Otoacoustic emission responses, MOC reflex results, and frequency-specific and total suppression findings were compared between the groups. The relationship between clinical and laboratory findings for the AS patients, and the MOC reflex data were also investigated. RESULTS Reduced MOC reflex response (p = 0.04) and suppression (p = 0.019) were detected in AS patients. When the clinical and laboratory findings for the AS patients and the MOC reflex test results were compared, a significant correlation was found only between the MOC reflex and the erythrocyte sedimentation rate. CONCLUSION The results showed that AS can damage the inner ear, especially the MOES, and can reduce the MOC reflex response without clinical hearing loss.

Abstract
The objective of the present study was to test the hypothesis that the addition of hyaluronic acid-based matrix to collagenated heterologous bone graft for sinus augmentation would enhance bone formation compared to collagenated heterologous bone graft alone in the early healing period, by micro-computed tomography and histomorphometry. Thirteen systemically healthy patients requiring bilateral two-stage maxillary sinus augmentation (residual crest height≤4mm) were enrolled in this split-mouth prospective randomized controlled study. One sinus side as a control group was grafted with only collagenated heterologous bone graft; the other region as a test group was grafted with hyaluronic matrix and collagenated heterologous bone graft. Bone biopsy samples were taken after 4 months during the dental implant surgery and analyzed using micro-computed tomography and histomorphometric parameters. According to the micro-computed tomography and histomorphometric results, a significantly higher percentage of new bone was observed in the test group when compared to the control group after 4 months of healing. This study confirmed the hypothesis that the addition of hyaluronic matrix to collagenated heterologous bone graft for sinus augmentation enhances bone formation compared to collagenated heterologous bone graft alone in the early healing period.

Abstract
Background Bell's palsy (BP) is the most common acute mononeuropathy of unilateral facial paralysis. Immune, infective and ischaemic mechanisms are potential contributors to the development of BP, but the precise cause remains unclear. Recently, oxidative stress has been proposed as a risk factor of various idiopathic diseases. The aim of this study was to investigate the possible role of oxidative stress in patients with BP. Methods Thirty-two patients with BP and 30 healthy controls were included in this study. Serum total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) were measured by the Erel method. Results Serum TOS activities and OSI values were significantly higher in patients with BP compared with the control group (P <0.003 for all comparisons), whereas there was no significant difference between the groups in terms of TAS levels (P >0.05). Conclusions The data suggest that oxidative stress is increased in BP. These results of high oxidative stress in patients with BP may be helpful to clarify the etiopathogenesis of BP and contribute to improvement in the management or prevention of the disease.

Abstract
INTRODUCTION The aim of this study was to evaluate the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) in patients with recurrent aphthous stomatitis (RAS). MATERIALS AND METHODS Eighty patients who were diagnosed with RAS between January 2014 and January 2016 were included in this study. Eighty age- and gender-matched healthy subjects were also enrolled as a control group. Neutrophil, lymphocyte, and platelet counts were compared between groups, in addition to NLR, PLR, and MPV values. RESULTS There was no significant difference in terms of lymphocyte count, platelet count, PLR, or MPV values between the two groups (P>0.05). However, white blood count, neutrophil count, and NLR were significantly higher in patients with RAS compared with the control group (P<0.05). CONCLUSION The present study revealed an increased NLR among RAS patients compared with healthy controls. This suggests that development of RAS involves an inflammatory process. We believe that NLR could be used as a cheap and simple marker of inflammation.

Abstract
Thymoquinone has antioxidant properties. We hypothesized that thymoquinone may prevent or alleviate hearing loss induced by acoustic trauma. We aimed to study thymoquinone's effect on hearing function with distortion-product otoacoustic emissions and auditory brainstem response. Thirty adult Spraque Dawley rats were randomized into four groups following exposure to acoustic trauma for 4 h. Control group (n = 7) did not receive further treatment. Thymoquinone-20 (n = 8) and Thymoquinone-40 (n = 8) received 20 and 40 mg/kg of intraperitoneal thymoquinone, respectively. Corn-oil group (n = 7) received 1 ml of corn oil intraperitoneally. Hearing function of both ears was tested with distortion-product otoacoustic emission and auditory brainstem response before, and shortly after acoustic trauma, and 96 h following acoustic trauma. Post-trauma signal/noise ratios and wave V amplitude/latencies of all groups were significantly low compared with pre-trauma values, which indicate no preventive effect of thymoquinone. Rats in Thymoquinone-20 showed a significantly improved distortion-product otoacoustic emission and auditory brainstem response results at 4000 frequency and above in post-treatment tests (p < 0.05). Improvement in Thymoquinone-40 at the same frequencies was insignificantly inferior to Thymoquinone-20, yet superior to control and corn-oil groups (p < 0.05). We conclude that thymoquinone may not prevent acoustic trauma-induced hearing loss, however, at 20 mg/kg for 96 h, may repair the damage.

Abstract
OBJECTIVE Amelogenesis imperfecta (AI) is a heterogenous genetic disorder that interferes with normal enamel formation in the absence of systemic disorders. The patients' main concerns are caries susceptibility, poor esthetics, and generalized sensitivity. There is a broad clinical spectrum, from discolorations to consequent enamel alterations. This case report describes the 15-year case study and the full-mouth rehabilitation of two siblings affected by a hypocalcified AI. Clinical Considerations: In these two patients, conservative care with stainless steel crowns and direct composite restorations was undertaken to restore function and esthetics and to reduce sensitivities in primary and mixed dentitions. The difficulties in monitoring resulted in severe infectious complications (dental abscess with cutaneous fistula), important dental defects, and loss of spaces with subsequent malocclusion. In the young adult dentition, they were treated by extractions, root canal therapies, and new restorations: stainless steel crowns for permanent molars, direct composite restorations (with strip crowns) for incisors and maxillary canines (to improve the crown morphology as well as to mask the discolorations and the malpositions), and adjusted composite crown molds using a thermoforming procedure for premolars and the mandibular canines. The main difficulties were rapid tooth surface loss, bonding to atypical enamel, developing dentition, long-term follow-up. CONCLUSION Restoring function and esthetics in AI-affected patients is a challenge from primary to adult dentition. Early corrections are essential to avoid dental damage and for psychological benefits. This clinical report highlights the adhesive rehabilitation for anterior and premolar areas and the difficulty of patient follow-up.

Abstract
Conclusion Eustachian tube (ET) dysfunction, which plays a role in the pathogenesis chronic suppurative otitis media (CSOM), does not seem to be due to differences in paratubal structures. Objective The aim of this study was to compare the magnetic resonance imaging (MRI) findings of the paratubal structures of the ET between normal ears and ears in patients with CSOM. Methods The MRI records of 40 patients who underwent tympanomastoidectomy for a diagnosis of CSOM were reviewed retrospectively. The healthy ears served as the control group. The length, diameter, surface area and volume of the tensor veli palatini muscle (TVPM) and levator veli palatini muscle (LVPM) were measured, in addition to the diameter of the pharyngeal orifice of the ET, volume of the Ostmann fat pad, bimucosal thickness of the lumen of the ET, and mucosal thickness. Results In the pathological ears, the mean length of the TVPM and LVPM was 22.6 mm and 19.3 mm, the mean diameter was 3.2 and 5.3 mm, and the mean volume was 1.75 and 3.2 cm(3), respectively. In addition, the mean diameter of the pharyngeal orifice of the ET was 1.9 mm. There were no significant between-group differences in the paratubal structures (p > 0.05).

Abstract
OBJECTIVES Identification of the most common aeroallergens to which patients are sensitized in a specific area is important in the diagnosis and treatment of allergic rhinitis (AR). We determined the distribution of aeroallergens, detected by skin-prick tests (SPT), in adult patients with AR in the Eastern Black Sea region of Turkey and compared the results with the other regions of Turkey and in the world. METHODS The medical records of SPT performed on 1457 patients with symptoms of AR (with regard to the Allergic Rhinitis and its Impact on Asthma 2008 guidelines) between March 2010 and March 2013 were analyzed retrospectively. SPT were carried out with the same panel, which included grass; weeds; trees; mold; epidermal mixtures; and with two house-dust mite (HDM) extracts, Dermatophagoides pteronyssinus and Dermatophagoides farinae. RESULTS In 1229 of 1457 patients (84.4%), there were positive reactions for at least one aeroallergen on the SPT. The most common aeroallergen was the HDM D. pteronyssinus (84% [n = 1033]) followed by D. farinae (78.2% [n = 962]). Grass pollen sensitivity (70.8% [n = 871]) was higher than tree or weed pollen sensitivity in this region. CONCLUSIONS The most common aeroallergens in AR are HDMs of D. pteronyssinus and D. farinae in the Eastern Black Sea region in Turkey. Our study may help in developing environmental control strategies for AR.

Abstract
OBJECTIVE Studies on the use of wideband tympanometry (WBT) for the evaluation of middle ear pathologies have been increasing gradually in recent years. However, studies regarding normative data of WBT are not sufficient. The aim of this study was to determine normative values of WBT for different age groups in Turkish population. MATERIALS AND METHODS One hundred fifty volunteers from five age-related groups were included in this study. Values of resonance frequency (RF), absorbance percentage according to frequency, maximum absorbance ratio, and maximum absorbance frequency were obtained using WBT. Measurements were recorded at a pressure of 0 decapascal (daPa) using a sound stimulus given at 90±3 decibel sound pressure level (dB SPL). RESULTS The RF was detected to be significantly lower only in the group of subjects in the age range of 0-1 month. The absorbance value at 250 Hz was detected to be significantly higher in the age groups of 0-1 month and 1 month-2 years than in the other groups. CONCLUSION We believe that the findings obtained in this study would be helpful in determining normative data regarding WBT; by the determination of this normative data, the clinical use of WBT would become widespread.
