Voice gains following thyroplasty may improve over time.

Type I thyroplasty for unilateral vocal fold paralysis restores voice. The purpose of this study was to evaluate measures of voice before thyroplasty, and at 3 months and 1 year after surgery. Of interest was whether vocal improvement in the first weeks after surgery was maintained or even enhanced over time. A total of 40 patients with unilateral paralysis underwent type I thyroplasty with or without arytenoid adduction. Perceptual, acoustic and aerodynamic measures of voice were studied. Perceptual analysis determined that optimal postoperative voice quality evolved over the first year. Acoustic indices of perturbation demonstrated progressive improvement over 12 months, whereas pitch and intensity ranges were increasingly extended. Postoperative glottal flow rates were normalized and phonation times were significantly longer, with benefits maintained over time. All perceptual, aerodynamic and acoustic measures of voice were improved 3 months after thyroplasty, with many measures further improved at 1 year. Such findings provide evidence that voice outcome progressively evolves over the first 12 months after surgery.

Developing, evaluating and maintaining a standardized stormwater BMP effectiveness database.

The Urban Water Resources Research Council of the American Society of Civil Engineers, under a cooperative agreement with the US Environmental Protection Agency, released Version 1.0 of the National Stormwater Best Management Practices (BMP) Database to the stormwater management community in 1999. The product included a loaded database of 71 BMPs, as well as data entry software for standardized reporting of BMP test data. In conjunction with the database, the project team developed BMP performance evaluation protocols and applied them to the data contained in the initial database. Since the initial database release, 42 new BMP data sets have been added to the database, which is now accessible via the Internet at www.bmpdatabase.org along with associated data evaluation reports and other project documentation. A national stormwater BMP data clearinghouse continues to screen and post new BMP data to the database, as well as respond to inquiries from the public. An overview of both of the database software and results of the data evaluation are provided in this paper.

Quality-of-life assessment in patients with unilateral vocal cord paralysis.

OBJECTIVE: Our objective was to identify the impact of unilateral vocal cord paralysis (UVCP) on an individual's quality of life both before and after thyroplasty. STUDY DESIGN AND SETTING: This was a prospective observational outcome study of consecutive patients presenting to a laryngology clinic with UVCP. Participants received The Medical Outcomes Study Short Form 36-Item Health Survey (SF-36), the Voice Handicap Index (VHI), and the Voice Outcome Survey (VOS). Patients underwent medialization laryngoplasty with silastic, with or without arytenoid adduction. Outcome measures were repeated after surgery. RESULTS: A review of 45 patients at presentation revealed statistically significant reductions in quality of life as measured by each survey. Marked improvements were noted after surgery. CONCLUSIONS: Our preoperative data support a profile of significant general health-related and voice-related limitations caused by UVCP. Patient perceptions improved significantly after the surgical treatment of glottal insufficiency. SIGNIFICANCE: The SF-36, VHI, and VOS provide an important complement to traditional endpoints in the analysis of patients with UVCP.
