Radiological Evaluation of Inner Ear with Computed Tomography in Patients with Unilateral Non-Pulsatile Tinnitus.

OBJECTIVE: The objective of this research was to investigate the possible relationship between tinnitus and certain bony inner ear structures using computed tomography (CT). MATERIALS AND METHODS: This was a prospective, controlled, double-blind study. The subjects of the study were divided into the following three groups: group 1 (G1), patients with unilateral sensorineural hearing loss (SNHL) and unilateral non-pulsatile tinnitus in the same ear; group 2 (G2), patients with normal hearing and unilateral non-pulsatile tinnitus; and group 3 (G3), healthy volunteers with neither tinnitus nor hearing loss. The basal turn length, internal acoustic canal (IAC) width and length, bony cochlear nerve canal (BCNC) width, and IAC diameter at the porus acousticus internus (PAI) were measured. RESULTS: The mean BCNC width was significantly narrower in G1 and G2 than in the control group (G3) (p<0.001). For patients in G2, BCNC width was significantly narrower in ears with tinnitus (p<0.001) than in ears without tinnitus. The mean IAC diameter at PAI was also narrower in the G1 patients (p=0.007) compared with the other groups. CONCLUSION: The results of this study suggest that CT evaluation of the inner ear structures is important in patients with tinnitus. According to the results, a narrow BCNC may cause phantom sensations and be related to cochlear nerve dysfunction. Therefore, it is recommended that clinicians evaluate BCNC carefully while assessing such patients.

Medical adherence to intranasal corticosteroids in adult patients / Adesão clínica a corticosteroides intranasais em pacientes adultos

Abstract Introduction: The adherence to medical treatment in allergic rhinitis is poorly evaluated in clinical practice. Objectives: To evaluate adherence to intranasal corticosteroids in the treatment of allergic rhinitis patients. Methods: This prospective study was conducted on adult patients who were admitted to the outpatient clinic of the otolaryngology department tertiary hospital. Patients diagnosed with moderate to severe persistent AR and who had not used any nasal sprays were enrolled in the study. The patients were provided with mometasone furoate nasal sprays. On the 30th day, all participants filled out a questionnaire regarding the factors that may have influenced their adherence to the treatment. Afterwards, each patient filled out the Turkish-language-validated Morisky Medical Adherence Scale (MMAS-8) form. Each factor that may have affected adherence to the prescribed medication was evaluated according to the MMAS-8 score and all variables were analyzed statistically. Results: Fifty-nine adult patients with a mean age of 32.5 years (range 21-52 years) were included in the study. The mean overall MMAS-8 score was 3.64. Two factors were significantly related to low adherence: number of dependent children (p = 0.001) and benefit from the medication (p = 0.001). In addition, patients with higher education levels seemed to be more adherent than the rest of the group. Conclusion: Clinicians must keep in mind the factors related to non-adherence in order to achieve better treatment outcomes. Therefore, based on our results, patients must be informed that medications should be taken properly regardless of the benefit, and the treatment should be scheduled with respect to daily activities, particularly for patients caring for more than two children.

Resumo Introdução: A adesão ao tratamento clínico de rinite alérgica é mal avaliada na prática clínica. Objetivos: Avaliar a adesão aos corticosteroides intranasais no tratamento de pacientes com rinite alérgica. Método: Este estudo prospectivo foi realizado com pacientes adultos admitidos no ambulatório do setor de otorrinolaringologia de um hospital terciário. Os pacientes diagnosticados com rinite alérgica moderada a persistente grave que não haviam ainda usado spray nasal foram incluídos no estudo. Os pacientes receberam sprays nasais de furoato de mometasona. No 30° dia, todos preencheram um questionário sobre os fatores que podem ter influenciado a sua adesão ao tratamento. Depois disso, cada paciente preencheu o formulário da Escala de Adesão Clínica Morisky validado para a língua turca (MMAS-8). Cada fator que pode ter afetado a adesão à medicação prescrita foi avaliado de acordo com o escore de MMAS-8 e todas as variáveis foram analisadas estatisticamente. Resultados: Foram incluídos no estudo 59 pacientes adultos com média de 32,5 anos (variação de 21-52). O escore total médio de MMAS-8 foi de 3,64. Dois fatores foram significantemente relacionados com a baixa adesão: número de dependentes infantis (p = 0,001) e benefício da medicação (p = 0,001). Além disso, os pacientes com níveis de ensino mais elevados pareceram ser mais adesistas do que o restante do grupo. Conclusão: Os médicos devem estar cientes dos fatores relacionados à falta de adesão, a fim de alcançar melhores resultados do tratamento. Portanto, com base em nossos resultados, os pacientes devem ser informados de que os medicamentos devem ser usados adequadamente independentemente do benefício, e o tratamento deve ser programado com relação às atividades diárias, especialmente para os pacientes que cuidam de mais de dois filhos.

How can we improve medical adherence to intranasal corticosteroids in children?

OBJECTIVE: To evaluate the factors which may be related to nonadherence to intranasal corticosteroids (ICS) in the treatment of allergic rhinitis (AR) in children. METHODS: A prospective study was conducted on children with AR diagnosis in a tertiary referral hospital. All participants were provided with mometasone furoate nasal sprays for 30 days after the diagnosis. Caregivers were called back when the therapy was over and completed a questionnaire about the factors that may influence the adherence to the treatment. Afterwards each caregiver completed the Turkish language validated Morisky Medical Adherence Scale (MMAS-8) form. Each factor was evaluated according to MMAS-8 score and all variables were analyzed statistically. RESULTS: A total number of 76 children with a mean age of 7.82 years were included in the study. The mean overall MMAS-8 score was 2.80. There was only one factor significantly related to low adherence; the number of dependent children to the caregiver (p = 0.011). Besides this 71.51% of the answers to MMAS-8 scale were compatible with good adherence. CONCLUSION: The clinician must consider the factors which may lead to non-adherence while setting up a treatment plan. The demographic and sociocultural factors must be taken into consideration and treatment schedule should be made in respect of daily activities of the children. Moreover the father can be involved in the therapy plan and back up the mother as they are usually the responsible parent for children's medical therapy.

A possible cause of epistaxis: increased masked hypertension prevalence in patients with epistaxis / Uma possível causa de epistaxe: maior prevalência de hipertensão mascarada em pacientes com epistaxe

Abstract Introduction Epistaxis and hypertension are frequent conditions in the adult population. Masked hypertension is defined as a clinical condition in which a patient's office blood pressure level is <140/90 mmHg, but the ambulatory or home blood pressure readings are in the hypertensive range. Many studies have proved that hypertension is one of the most important causes of epistaxis. The prevalence of this condition in patients with epistaxis is not well defined. Objective This study aimed to evaluate the prevalence of masked hypertension using the results of office blood pressure measurement compared with the results of ambulatory blood pressure monitoring. Methods Sixty patients with epistaxis and 60 control subjects were enrolled in the study. All patients with epistaxis and controls without history of hypertension underwent physical examination, including office blood pressure measurement, ambulatory or home blood pressure, and measurement of anthropometric parameters. Results Mean age was similar between the epistaxis group and the controls – 21–68 years (mean 42.9) for the epistaxis group and 18–71 years (mean 42.2) for the control group. A total of 20 patients (33.3%) in the epistaxis group and 7 patients (11.7%) in the control group (p = 0.004) had masked hypertension. Night-time systolic blood pressure was significantly higher in patients with epistaxis than in the control group (p < 0.005). However, no significant difference was found in daytime systolic blood pressure between the control group and the patients with epistaxis (p = 0.517). Conclusion This study demonstrates increased masked hypertension prevalence in patients with epistaxis. We suggest that all patients with epistaxis should undergo ambulatory or home blood pressure to detect masked hypertension, which could be a possible cause of epistaxis.

Resumo Introdução Epistaxe e hipertensão são condições frequentes na população adulta. Hipertensão mascarada é definida como uma condição clínica em que o nível da pressão arterial do paciente no consultório é < 140/90 mm Hg, mas as leituras da pressão arterial ambulatorial ou em casa se encontram na faixa hipertensiva. Muitos estudos demonstraram que a hipertensão é uma das causas mais importantes de epistaxe. Ainda não está devidamente definida a prevalência dessa condição em pacientes com epistaxe. Objetivo Avaliar a prevalência de HM com o uso dos resultados de mensurações da pressão arterial no consultório, em comparação com os resultados da MAPA. Método Foram recrutados 60 pacientes com epistaxe e 60 indivíduos para controle. Todos os pacientes com epistaxe e os controles sem histórico de hipertensão passaram por exame físico, inclusive determinação da pressão arterial no consultório, MAPA e mensuração dos parâmetros antropométricos. Resultados A média de idade foi similar entre o grupo com epistaxe e os controles: de 21 a 68 (média 42,9) anos para o grupo com epistaxe e de 18 a 71 (média 42,2) anos para o grupo controle. No total, 20 pacientes (33,3%) no grupo com epistaxe e sete (11,7%) no grupo controle (p = 0,004) apresentaram hipertensão mascarada. A pressão arterial sistólica noturna foi significantemente mais alta em pacientes com epistaxe, em comparação com o grupo controle (p < 0,005). No entanto, não foi observada diferença significante na pressão arterial sistólica obtida durante o dia entre o grupo controle e os pacientes com epistaxe (p = 0,517). Conclusão O presente estudo demonstra maior prevalência de hipertensão mascarada em pacientes com epistaxe. Sugerimos que todos os pacientes com epistaxe devam ser submetidos à monitoração da pressão arterial caseira ou em consultório com o objetivo de detectar hipertensão mascarada, que pode ser uma causa possível de epistaxe.

Allergens might trigger migraine attacks.

Migraine is a common primary headache disorder. The mechanisms underlying the onset of a migraine attack are not completely understood. Environmental changes and a number of other factors could induce migraine attacks. The aim of this study was to investigate the relationship between the frequency of migraine attacks and allergens. Migraine patients without aura, and healthy individuals similar in age and gender without a history of headache and allergy were prospectively included in the study. The duration of migraine, the frequency of migraine attacks, the medication history, and the symptoms during attacks were questioned. Migraine disability assessment score (MIDAS) and visual analog scale (VAS) scores were obtained. Allergen extracts including dust, fungi, insect, animal epithelium, pollens, and food allergens were applied for allergy tests. 49 migraine patients and 49 healthy individuals were enrolled in the study. There was no significant difference in terms of age and gender. The median migraine disease duration, the number of attacks in a month, and the duration of attacks were, respectively, 5.5 years (1-44), 4 (1-10) day/month, and 24 (4-72) h. The mean MIDAS grade was 2.45 ± 0.14 (1-4), and mean VAS score was 7.89 ± 0.27 (4-10). The positivity of allergy tests was 55.1 % (27/49) in the migraine group and 32.7 % (16/49) in the control group (p < 0.05). The allergy tests were positive for house dust, red birch, hazel tree, olive tree, nettle, and wheat. The frequency of migraine attacks was higher in allergy-test-positive patients than in negative ones in the migraine group (p = 0.001). The migraine patients who had frequent attacks should be examined for allergies.

The relationship between senile hearing loss and vestibular activity / Relação entre perda auditiva senil e atividade vestibular

Abstract Introduction: A considerable high number of SNHL patients also suffer from dizziness and related vestibular symptoms. Objective: To evaluate the association of vestibular dysfunction and sensorineural hearing loss (SNHL) in adult patients. Methods: Prospective, double-blinded, controlled studies composed by 63 adult patients without any vestibular symptoms or diagnosed vestibular diseases. Audiological status was measured with pure tone audiometry and the vestibular system was tested with vestibular evoked myogenic potential (VEMP). Patients were divided into two groups: a study group (patients with SNHL) and a control group (patients without SNHL). VEMP results of the groups were calculated and compared. Results: Mean P1 (23.54) and N1 (30.70) latencies were prolonged in the study group (p < 0.001) and the amplitudes of the study group were significantly reduced (p < 0.001). Both parameters of the VEMP test were abnormal in the study group when compared to the control group. Conclusions: These findings suggest that age-related SNHL may be accompanied by vestibular weakness without any possible predisposing factors for vestibulopathy.

Resumo Introdução: Um número considerável de pacientes com PANS também sofre de tonturas e sintomas vestibulares relacionados. Objetivo: Avaliar a associação entre disfunção vestibular e perda auditiva neurossensorial (PANS) em pacientes adultos. Método: Estudo prospectivo, duplo-cego e controlado com 63 pacientes adultos, sem quaisquer sintomas vestibulares ou doença vestibular diagnosticada. A audição foi avaliada por meio de audiometria tonal e o sistema vestibular, com potenciais evocados miogênicos vestibulares (PEMV). Os pacientes foram divididos em dois grupos: grupo de estudo (pacientes com PANS) e grupo de controle (pacientes sem PANS). Os resultados dos PEMV dos grupos foram calculados e comparados. Resultados: As latências médias de P1 (23,54) e N1 (30,70) encontravam-se prolongadas no grupo de estudo (p < 0,001), e as amplitudes no grupo de estudo estavam significantemente reduzidas (p < 0,001). Ambos os parâmetros do teste de PEMV foram anormais no grupo de estudo quando comparados aos do grupo controle. Conclusões: Nossas achados sugerem que a PANS relacionada à idade pode ser acompanhada por hipofunção vestibular, mesmo na ausência de possíveis fatores predisponentes para vestibulopatia.

Evaluation of cochlear functions in children with Familial Mediterranean Fever.

OBJECTIVES: To evaluate cochlear functions in patients with Familial Mediterranean Fever in relation to the disease severity score and treatment duration. METHODS: 50 patients (4-18 years) who had been followed-up with the diagnosis of FMF and regularly receiving appropriate colchicine treatment and 39 healthy controls were included in the study. All the patients and controls were evaluated by audiologic evaluation, including high-frequency pure-tone audiometry and distortion product otoacoustic emission tests (DPOAE). The disease severity was determined by scoring system developed by Pras et al. RESULTS: Fifty patients (52% female, 48% male; mean age12.2 ± 4.1 years) and 39 controls (58.9% female, 41.1% male, mean age 11.1 ± 3.4 years) were enrolled the study. The pure tone average of FMF patients was significantly higher than that of the control group at 500, 4000, and 8000 Hz frequencies. The patients' DPOAE signal values at 6 kHz, 8 kHz frequencies and SNR values at 8 kHz were significantly higher than control group. The patients' audiometry and DPOAE results were compared with the disease severity scores. Pure tone average was significantly higher in severe and moderate patient groups compared to the mild patient group at 2000 Hz frequency. DPOAE signal values showed statistically significant differences between the patient severity scores at 1.4 and 2.8 kHz frequencies. The mean colchicine treatment duration was found to be 5.1 ± 3.7 years. There were significant differences at 250 and 500 Hz frequencies when patients' audiometry results were compared with the treatment periods. CONCLUSIONS: FMF affects cochlear functions particularly at high frequencies.

Comparison of autogeneous and homogeneous nasal dorsal onlay grafts in an experimental design.

An experimental model was used for the comparative evaluation of autogeneous and homogeneous nasal dorsal onlay cartilage grafts. This study was conducted on 18 adult white New Zealand male rabbits. Nasal septal cartilage (NSC), sliced nasal septal cartilage (SNSC) and auricular cartilage (AC) grafts were prepared in autogeneous and homogeneous forms and placed into the subcutaneous pockets of the nasal dorsum of rabbits. After a period of 3 months, the animals were painlessly killed, and each site was analyzed histologically for inflammation, neovascularization, fibrosis and resorption. Inflammation, fibrosis and neovascularization were found to be significantly more extensive in the homogeneous graft groups and autogeneous SNSC group 3 months after implantation. Resorption was significantly high in both homogeneous and autogeneous AC groups and significantly low in the autogeneous and homogeneous SNSC groups. There was no significant difference between the homogeneous and autogeneous grafts in terms of resorption rates. In conclusion, the results of this experimental study demonstrate that resorption was lesser than expected in the sliced cartilage graft and that homologous cartilage graft applications had activity and reliability similar to that of autogenous cartilage grafts.

Comparison of risk factors in newborn hearing screening in a developing country.

The aim of this study is to evaluate the results of the newborn-hearing screening program (NHSP) in our institute, investigate the risk factors and their correlation to congenital hearing loss (CHL). Newborns who admitted to our clinic for NHSP from June 2014 to December 2014 were included in the study. After the test parents were asked to fill a questionnaire about the risk factors of CHL. Test results and referral rate were compared with risk factors. One thousand consecutive babies were included in the study. The overall referral rate was 3.5%. Mechanic ventilation, history of familial CHL and familial consanguinity were found to be significantly related to CHL.In the light of our results we can conclude that getting access to every newborn for hearing screening is mandatory and targeting the risk factors and informing the family about the follow-up period is important for diagnosing the delayed hearing impairment.

Accuracy of Internet guidance on pediatric otolaryngology procedures.

OBJECTIVES: To evaluate the reliability and accuracy of the most visited Internet websites for the frequently performed surgical pediatric otorhinolaryngology procedures. STUDY: A google.com search was used to determine the top 20 Internet sites for the terms 'adenoidectomy', 'tonsillectomy' and 'ventilation tube surgery'. The DISCERN plus questionnaire was used to score each website. Furthermore, a 'hit list' of reliable and accurate websites was created depending on the most clicked healthcare organizations with corporate identities and the personal websites of the otolaryngologists with academic titles who were members of the Turkish Society of Otolaryngology Head and Neck Surgery. The pages were also investigated as if they were in this list of accurate websites. RESULTS: Of the 60 websites viewed for the terms 'adenoidectomy', 'tonsillectomy' and 'ventilation tube surgery', only 23.3% were matching the list of accurate websites. The mean DISCERN plus score was 35.70 (16-58), 38.02 (16-80) and 39.08 (16-58) for adenoidectomy, tonsillectomy and ventilation tube surgery respectively. There was no significant difference between the three groups (p>0.05). The mean DISCERN plus score for all the websites was 37.37 out of the maximum score of 80. CONCLUSIONS: In the light of our results we can conclude that the quality of data on the Internet is not adequate enough to obtain information about the most frequent surgical procedures in pediatric otorhinolaryngology. Clinicians must be aware about this fact and warn the parents about the disinformation which may lead to wrong decisions.

Investigation of middle ear pressure changes during prone position under general anesthesia without using nitrous oxide.

PURPOSE: The effects of different body positions on the middle ear were reported in several studies, but there are no data about the effects on patients under general anesthesia. The aim of this study is to determine the effect of prone position on middle ear pressure (MEP) during general anesthesia without using nitrous oxide. METHODS: Twenty patients under general anesthesia during prone position were included in the study. The performed anesthesia method was the same for all patients. Remifentanil was used for analgesia instead of nitrous oxide. MEPs were measured 5 times with a middle ear analyzer: before induction (BI), after intubation (AI), after turned to the prone position (PP1), at the end of the prone position (PP2), and after returned to the supine position (SP). Duration of prone position was also recorded. RESULTS: Of the 20 patients were 11 women and 9 men with a 49 ± 13 mean age. BI-AI, AI-PP1, PP1-PP2, and PP2-SP comparisons of both MEPs were statistically significant (P < 0.0001). Right mean MEPs were BI, -1 ± 23 daPa; AI, 41 ± 51 daPa; PP1, 124 ± 76 daPa; PP2, 152 ± 59 daPa; and SP, 63 ± 29 daPa; whereas left mean MEPs were BI, -24 ± 55 daPa; AI, 28 ± 34 daPa; PP1, 132 ± 67 daPa; PP2, 162 ± 48 daPa; and SP, 70 ± 89 daPa. Significant increases were detected at the start and continuation of the prone position. The mean duration of prone position was 98 ± 51 per minute. CONCLUSIONS: The significant MEP increases during the prone position under general anesthesia depend on a number of reasons. Among them are inhaler agents, pressure changes in mucosal blood vessels due to venous congestion, and the mastoid bone volume. Further researches are required to determine and explain the mechanisms of increase in MEP during prone position.

Transoral robotic surgery for atypical carcinoid tumor of the larynx.

In recent years, transoral robotic surgery has been introduced as an efficient and a reliable method for excision of selected oral cavity, tongue base, and supraglottic tumors in otolaryngology. In this case report, a 39-year-old woman with a history of hoarseness and dysphagia for approximately 6 months is presented. The patient was diagnosed with atypical carcinoid tumor on the laryngeal aspect of the epiglottis, and excision of the tumor was performed through transoral robotic surgery using the robotic da Vinci surgical system, a 0-degree three-dimensional endoscope, 5-mm microinstruments compatible with the da Vinci robot, and a Feyh-Kastenbauer/Weinstein-O'Malley retractor. The mass was removed completely, and no complications occurred. The patient recovered without a need for tracheotomy. Findings of the 1-year clinical follow-up revealed no locoregional recurrence or distant metastasis. This case shows, once again, that transoral robotic surgery could be used safely and effectively regardless of pathologic diagnosis in the supraglottic region tumors.

Effect of laryngoscopy on middle ear pressure during anaesthesia induction.

AIMS: The procedure of laryngoscopic orotracheal intubation (LOTI) has many impacts on several parts of the body. But its effect on middle ear pressure (MEP) is not known well. The purpose of this study is to evaluate the MEP changes subsequent to insertion of endotracheal tube with laryngoscope. SUBJECTS AND METHODS: 44 patients were included in this study with a normal physical examination of ear, nose and throat. A standard general anaesthesia induction without any inhaler agent was performed to the all patients. The MEP measurements for both ears were applied under 1 minute; before induction (BI) and after intubation (AI) with a middle ear analyzer. Also hemodynamic parameters were recorded before induction and after intubation. RESULTS: Of the 44 patients were 25 women and 19 men with a 43.5±15.1 mean age. A statistically significant rise in MEP was seen in all patients subsequent to insertion of endotracheal tube (P<0.05). Mean right MEPs were BI: -9.5 and AI: 18.5 daPa. Also mean left MEPs were BI: -21.7 and AI: 29.1 daPa. The amount of increases in left and right MEPs were 50 daPa and 27 daPa, respectively. 20% increase in systolic blood pressure and 19% increase in diastolic blood pressure were determined after intubation. The mean heart rate was 76/min before intubation, whereas it was 102/min after intubation with a 34% increase. CONCLUSION: In this study bilateral significant increases in MEP were determined subsequent to LOTI. Possible factors affecting MEP may be auditory tube, size and type of the blades, drugs and face masking time. But on the other hand in our opinion cardiovascular and haemodynamic response to LOTI has the most impact over the middle ear mucosa with mucosal venous congestion.

Laryngeal fibrous hamartoma presenting with airway obstruction at birth.

Hamartoma is an extremely rare congenital malformation of the larynx. Hamartomas of the nasal cavity or nasopharynx are classified as epithelial, mesenchymal, and mixed epithelial and mesenchymal types. Presenting symptoms result from airway obstruction and may include slowly rising respiratory distress, stridor, changes in voice, eating, and activity levels. We present a 1-day-old newborn with a history of stridor and respiratory distress caused by a polypoid mass on the anterior half of the left ventricular band. We performed an excisional biopsy under direct laryngoscopy. Histopathologic finding after excisional biopsy was consistent with hamartoma. We report and discuss the pathological features and differential diagnosis of this rare laryngeal hamartoma. To our knowledge, laryngeal hamartoma presenting with stridor has not been described in the literature thus far.

Audiologic evaluation in pediatric patients with type 1 diabetes mellitus.

OBJECTIVE: The aim of this study was to perform audiological evaluation of children with type 1 diabetes mellitus (DM). METHODS: One hundred DM patients (200 ears) were included in the study. Pure-tone audiometry at frequencies of 0.25, 0.5, 1, 2, 4, and 8 kHz; immittance measures including tympanometry and acoustic reflex testing; transient evoked otoacoustic emission (TEOAE); and auditory brainstem response (ABR) testing were performed in the patients. The results were statistically compared with metabolic control of DM, positive and negative autoantibodies, duration of DM, and present concomitant Hashimoto and celiac diseases. RESULTS: The proportion with a result of 'fail' for the TEOAE test in the DM patients was not statistically significant among all groups (p > 0.05). The autoantibodies, blood glucose level, and present concomitant Hashimoto and celiac diseases were not associated with prolonged ABR latencies. However, ABR peripheral transmission time (wave I) was significantly delayed with the increasing duration of DM (p < 0.05). CONCLUSION: Pediatric patients with type 1 DM do not frequently present with cochleovestibular symptoms, but show higher audiometric thresholds and the absence of or reduction in TEOAE amplitudes. In ABR testing, the increase in the peripheral transmission time (wave I) is more suggestive of retrocochlear alterations in pediatric cases of type 1 DM compared with conventional audiometric tests (e.g., pure-tone audiometry and OAEs), which may indicate possible initial auditory neuropathy. Further longitudinal investigations on a wide range of control and pediatric subjects with DM will be necessary to confirm the present data and to detect initial auditory neuropathy.
