Effects of Radiofrequency and Intranasal Steroid Treatments on Respiratory and Olfactory Functions in Nasal Obstruction

WOS: 000330078200047PubMed: 23715004Objective: This study aimed to compare the effectiveness of radio-frequency ablation (RFA) and intranasal steroid (INS) treatments on respiratory and olfactory functions in patients with inferior concha hypertrophy and chronic nasal obstruction. Study Design and Setting: This was a prospective clinical trial performed at a tertiary referral center. Methods: We assessed patients with nasal obstruction between July 2011 and February 2012. The severity of the nasal obstruction in both groups was determined before treatment and 3 months after using a visual analog scale. For the purpose of an objective test, assessment was performed by the acoustic rhinometry. Using Sniffin' Sticks for test odor identification, the discrimination and thresholds were assessed in both groups. Results: The visual analog scale score after treatment was significantly lower in each group. Radiofrequency ablation treatment significantly improved the right minimal cross-sectional area 1 (MCA1), mean MCA1, and volume 1, as well as the right MCA2, mean MCA2, volume 2, and total volume. In the INS group, improvement was detected for the left MCA1, mean MCA1, and volume 1. Minimal cross-sectional area 2, volume 2, and total volume improved significantly after RFA treatment, but not after INS treatment. Conclusions: Although RFA may be more effective in the posterior region of the nasal cavity, INS and RFA used in the treatment of inferior concha hypertrophy both had favorable effects on respiratory function. Intranasal steroid treatment provided improved discrimination and total score values, whereas RFA treatment improved only odor identification

Effects of Systemic Immunotherapy on Olfactory Function in Allergic Rhinitis Patients

WOS: 000340257800017PubMed: 25006938Objective: Allergic rhinitis (AR), a chronic inflammatory disorder of the nasal mucosa, affects approximately 20% of the world's population and often causes olfactory dysfunction. Conventional treatments cannot cure it, but only alleviate and control the symptoms. Systemic immunotherapy (SIT) is the only curative treatment for AR, but its positive effect on olfactory function has not been quantitatively demonstrated. We measured the olfactory function in patients using a "Sniffin' Sticks'' test and analyzed the effects of subcutaneous SIT. Methods: The study included 12 patients (aged 13-44 years) who were eligible to receive subcutaneous SIT to treat AR between 2010 and 2012 in the Department of Otolaryngology, Sisli Etfal Training and Research Hospital. A 3-step Sniffin' Sticks test was performed before and 18 months after subcutaneous SIT. The data collected before and after treatment were compared for each patient. Results: The average scores for smell test parameters increased after treatment. Although improvements in the mean threshold, mean discrimination, and mean total scores were not significant, the mean identification score was significantly improved after treatment (P < 0.05). Age, sex, and smoking were not significantly related to the changes in the parameters. Conclusions: Subcutaneous SIT improved the olfactory performance in AR patients. Additional studies with larger patient populations and longer follow-up periods are needed to establish subcutaneous SIT as an effective treatment for olfactory disorders in these patients

Does the use of radiofrequency myringotomy for insertion of a ventilation tube reduce the incidence of myringosclerosis?

WOS: 000331706100007PubMed: 23494285The aim of the present study was to determine the rate of myringosclerosis after radiofrequency (RF) myringotomy and ventilation tube (VT) insertion and compare it with that after the incisional myringotomy and VT insertion. Thirty children (60 ears), 2-16 years old (mean age 7.06 +/- A 2.77 years) who were planned to undergo surgical intervention for bilateral otitis media with effusion (OME), were included in this study. The children were treated by RF myringotomy of the right ear, incisional myringotomy of the left ear, and insertion of VTs into both ears. Both ears were examined intraoperatively for bleeding, and patients were evaluated for myringosclerosis formation with otomicroscopy at the end of the ninth month. Myringosclerosis was observed in 22 of the 60 ears. The overall incidence was 36.6 %. Fifteen (50 %) left ears showed myringosclerosis by otomicroscopy, and seven (23.3 %) right ears showed myringosclerosis. The rate of myringosclerosis of the right ear was significantly lower than that of the left ear (p < 0.05). In addition, intraoperative tympanic membrane bleeding was observed in 24 (40 %) of the 60 ears: 21 (70 %) left ears and three (10 %) right ears were perforated by RF. The tympanic membrane bleeding rate of the right ear was significantly lower than that of the left ear (p < 0.01). The present study is the first to determine the myringosclerosis rate after RF myringotomy and VT insertion. Our results indicate that VT insertion with RF myringotomy decreased the incidence of myringosclerosis

Sonographic scoring of solid thyroid nodules: effects of nodule size and suspicious cervical lymph node

Abstract Introduction Ultrasound is the most frequently used imaging method to evaluate thyroid nodules. Sonographic characteristics of thyroid nodules which are concerning for malignancy are important to define the need for fine needle aspiration biopsy or open surgery. Objective To evaluate malignancy risk of solid thyroid nodules through sonographic scoring. The effects of nodule size ≥2 cm and associated pathologic cervical lymph node in scoring were examined in addition to generally excepted suspicious features. Methods Medical data of 123 patients underwent thyroid surgery were reviewed, and 89 patients (58 females, 31 males) were included in the study. The presence and absence of each suspicious sonographic feature of thyroid nodules were scored as 1 and 0, respectively. Total ultrasound score was obtained by adding the positive ultrasound findings. Differently from the literature, nodule size ≥2 cm and associated pathologic cervical node were added in scoring criteria. The diagnostic performance of nodule characteristics for malignancy and the effect of total US score to discriminate malignant and benign disease were calculated. Results A significant relationship was found between malignancy and hypoechogenity, border irregularity, intranodular vascularity, and microcalcification (p < 0.05). Pathologic cervical node was observed predominantly in association with malignant nodules. Positive predictive value of suspicious cervical node for malignancy was 67%, similar to microcalcification. Nodule size ≥2 cm was not distinctive for diagnosis of malignancy. The number of suspicious sonographic features obtained with receiver operating characteristic analysis to discriminate between malignant and benign disease was three. Conclusion Sonographic scoring of thyroid nodules is an effective method for predicting malignancy. The authors suggest including associated pathologic node in the scoring criteria. Further studies with larger cohorts will provide more evidence about its importance in sonographic scoring

Does the reduction of inferior turbinate affect lower airway functions?

Introduction: Although the nose and lungs are separate organs, numerous studies have reported that the entire respiratory system can be considered as a single anatomical and functional unit. The upper and lower airways affect each other either directly or through reflex mechanisms. Objective: In this study, we aimed to evaluate the effects of the radiofrequency ablation of persistent inferior turbinate hypertrophy on nasal and pulmonary function. Methods: Twenty-seven patients with bilateral persistent inferior turbinate hypertrophy without septal deviation were included in this study. All of the patients were evaluated using anterior rhinoscopy, nasal endoscopy, acoustic rhinometry, a visual analogue scale, and flow-sensitive spirometry on the day before and 4 months after the radiofrequency ablation procedure. Results: The post-ablation measurements revealed that the inferior turbinate ablation caused an increase in the mean cross-sectional area and volume of the nose, as well as in the forced expiratory volume in 1 s, forced vital capacity, and peak expiratory flow of the patients. These differences between the pre- and post-ablation results were statistically significant. The post-ablation visual analogue scale scores were lower when compared with the pre-ablation scores, and this difference was also statistically significant. Conclusion: This study demonstrated that the widening of the nasal passage after the reduction of the inferior turbinate size had a favorable effect on the pulmonary function tests. Resumo: Introdução: Embora o nariz e os pulmões sejam órgãos separados, numerosos estudos relataram que todo o sistema respiratório pode ser considerado como uma única unidade anatômica e funcional. As vias aéreas superiores e inferiores afetam uma à outra diretamente ou através de mecanismos reflexos. Objetivo: Avaliar os efeitos da ablação por radiofrequência em conchas nasais inferiores com hipertrofia persistente sobre a função nasal e pulmonar. Método: Foram incluídos neste estudo 27 pacientes com hipertrofia persistente bilateral de conchas inferiores sem desvio septal. Todos os pacientes foram avaliados com rinoscopia anterior, endoscopia nasal, rinometria acústica, escala visual analógica e espirometria sensível ao fluxo no dia anterior e quatro meses após o procedimento de ablação por radiofrequência. Resultados: As medidas pós-ablação demonstraram que a ablação das conchas nasais inferiores resultou em um aumento da área transversal média e do volume do nariz, bem como do volume expiratório forçado em um segundo, da capacidade vital forçada e do fluxo expiratório máximo dos pacientes. Essas diferenças entre os resultados pré e pós-ablação foram estatisticamente significantes. Os escores da escala visual analógica pós-ablação foram menores quando comparados com os escores pré-ablação e essa diferença também foi estatisticamente significante. Conclusão: O alargamento da passagem nasal após a redução do tamanho das conchas nasais inferiores teve efeito favorável nos testes de função pulmonar.
