Voice Assessment After Treatment of Subacute and Chronic Cough With Inhaled Steroids.

INTRODUCTION: Inhaled steroids are widely used for persistent cough treatment. Although the side effects of long-term inhaled steroids have been well described in the literature, their laryngeal side effects after short-term use have not yet been defined. The aim of this study was to evaluate the effect of 1 month application of inhaled steroid treatment on voice parameters in patients with subacute or chronic cough. Furthermore, the efficacy of inhaled steroids on cough was investigated, as well. MATERIAL AND METHODS: This study included 46 patients (27 females and 19 males) with a persistent cough lasting at least 3 weeks and treated with inhaled steroids. All patients were examined by a pulmonologist and lung auscultation where a posteroanterior chest X-ray and spirometry were performed. The patients were also examined by an otolaryngologist. Anterior rhinoscopy, flexible fiberoptic nasopharyngoscopy, and laryngostroboscopy were performed. Also, the patients' acoustic voice analyses were performed and recorded using a multidimensional voice program. Cough symptom index (CSI) scores were used to evaluate the response to treatment. Patients with an underlying disease that was unresponsive to inhaled steroids were excluded from study. The 46 patients were administered inhaled budesonide 400 mcg twice a day, for 1 month, and their acoustic voice analyses were performed again at the end of the treatment. In addition, CSI scores were determined after stopping medication. RESULTS: When pretreatment and posttreatment acoustic voice analysis parameters (Fo, Jita, Jitt, Shim, APQ, vAm, and NHR) were compared, statistically significant differences were detected for vAm (P = 0.001) and F0 (P0.003). After treatment with inhaled steroids, the CSI score reduced from 3 to 1 (median), and the difference was statistically significant. CONCLUSIONS: Inhaled budesonide treatment in the proper dose seems to be an effective treatment for persistent cough, in the selected patient group. In addition, short-term budesonide application did not cause any negative effects on the voice parameters in these patients. These findings may be related to the steroid formulation used, the application method, and the duration of treatment. Further studies are needed on a larger group of patients with different formulations of inhaled steroids to clarify aforementioned issues.

Use of botulinum toxin in voice restoration after laryngectomy.

BACKGROUND: Following laryngectomy, a distinct population of patients fails to achieve successful tracheoesophageal voice. These patients' voices range from strained and effortful to none at all. Such patients may present with severe hypertonicity or spasm of the pharyngoesophageal segment. Botulinum toxin has been used to chemically denervate the pharyngeal musculature, and is an alternative to invasive surgical procedures. The aim of this article is to review the evidence for using botulinum toxin to achieve an improvement in post-laryngectomy voice. METHODS: A Medline literature review (1966 to January 2009) and a search of the Cochrane database were performed. Foreign language articles and those not pertaining to post-laryngectomy voice restoration were excluded. RESULTS: Nine articles reporting a total of 134 patients were identified. Although there were differences in the outcome measures used, objective improvement in voice production occurred in between 70 and 100 per cent of cases. CONCLUSION: Botulinum toxin can be used as a safe and cost-effective treatment in patients with confirmed pharyngoesophageal segment hypertonicity and/or spasm following laryngectomy, to obtain an improvement in voice quality.

Voice changes in women treated for endometriosis and related conditions: the need for comprehensive vocal assessment.

Hormonal treatments which have an androgenic effect have the potential to cause vocal changes. The changes in vocal fold structure and voice quality are considered to be irreversible. To date, studies have documented subjective vocal changes or documented single cases without detailed, baseline voice assessments. The impact on laryngeal function of women taking these androgenic treatments requires further detailed, objective assessment. The need for increased awareness of the actions of androgenic hormones on womens' voices, and the benefits of a thorough voice assessment are discussed.
