Abstract

Background: Maximum phonation times (MPT) of vowels in adult women with vocal nodules.

Aim: To verify and to correlate the values of MPT of vowels in young and middle-aged adult women with vocal nodules.

Method: Database records from a speech therapy school-clinic were used, making up a total of 38 subjects.

Inclusion criteria: female adults, aged between 20 and 53 years, with otorhinolaryngology diagnosis of vocal nodules.

Exclusion criteria: to present a laryngeal pathology other than vocal nodules; hearing loss ; oral breathing; history of neurological, psychiatric, endocrine or gastric disorders; flu or allergy history; drinking and/or smoking habits; previous speech therapy and/or otorhinolaryngology treatments. Anamnesis data, the otorhinolaryngology diagnosis, and the MPT measurements of vowels /a, i, u/ were verified for each subject. MPT evaluation consisted of the duration measurement of three emissions of the vowels, using habitual tone and intensity, until the end of exhalation, with the patient in a standing position, considering the highest value of each vowel. The results were statistically analyzed with a significance level of 5%.

Results: Representative age range; less representative MPT and mean, below normality and with a strong positive and meaningful correlation; moderate, positive and significant correlation between MPTs and their means.

Conclusion: For the group of adult women with vocal nodules, the MPT values were reduced and positively correlated; the MPT of vowel /a/ presented a lower value when compared to the other investigated vowels.

有声带结节的成年女性元音的最大发声时间。
背景:有声带结节的成年女性元音的最大发声时间(MPT)。目的:验证中青年女性声带结节患者元音MPT值的相关性。方法:采用某语言治疗学校-诊所数据库记录,共38例。纳入标准:年龄在20 - 53岁之间,耳鼻喉科诊断为声带结节的成年女性。排除标准:有声带结节以外的喉部病理;听力损失;口腔呼吸;神经、精神、内分泌或胃疾病史;流感或过敏史;饮酒和/或吸烟习惯;既往语言治疗和/或耳鼻喉科治疗。对每位受试者的记忆数据、耳鼻喉科诊断以及元音/a、i、u/的MPT测量值进行验证。MPT评估包括测量三个元音发出的持续时间,使用习惯的音调和强度,直到呼气结束,患者站姿,考虑每个元音的最高值。对结果进行统计学分析,显著性水平为5%。结果:具有代表性的年龄范围;MPT与平均值的代表性较低,低于正态,具有较强的正相关和有意义;mpt与其均值之间存在中度、正、显著相关。结论:成年女性声带小结组MPT值降低且呈正相关;元音/a/的MPT值较其他元音低。
