Abstract
Assessment of voice is an integral part of managemenl of voice disorders. Voice evaluation includes:
1. Elementary diagnostic procedures, they are carried at most primary voice health care clinics.
2. Clinical diagnostic procedures, which require some advanced hardware. They are carried out at specialized voice clinics.
3. Additional instrumental measures, which are options for highly specialized voice laboratories.
A comparison of the first results of videokymography with videostroboscopy (Schutte et al, 1998) shows that the videokymographic approach considerably enriches stroboscopy. whereas many images are needed to evaluate the vibration pattern of the vocal folds produced by stroboscopy, videokymography is able to depict the pattern in one image. In this sense the method clarifies and adds precision to the stroboscopic results.
Although voice therapy is the cornerstone in treating MAPL’s, phonosurgen has an important role in some lesions. Conventional endolaryngeal microphonosurgery and laser surgery are the main procedures in phonosurgical treatment of MAPL’s. For smoother and quicker healing after phonosurgery, with or without postoperative voice therapy, the treatment team should guard against rough handling of the vocal fold mucosa or having a surgical wound with mucosal tags (Bouchayer and Cornut, 1992).
Controversy concerning the merits of CO2 laser in microphonosurgery of patients with MAPL’s is still present, because of potential adverse thermal effects on surrounding tissues and subsequent effects on voice quality. Sataloff et al., (1992), Zeitels (1996) preferred cold instruments, whereas Werkhaven and Ossoff (1991), Remacle et al., (1999) and Benninger (2000) appreciate the CO2 laser as a novel alternative to conventional microsurgery for benign vocal fold lesions.
