  • Background and Objectives : Vocal polyps and nodules are representative chronic benign laryngeal disease. Treatment options for vocal polyp and nodule in general include voice therapy or laryngeal microsurgery. The purpose of this study was to analyze voice results before and after laryngeal microsurgery. Materials and Method: Vocal polyp and vocal nodule patients were treated by laryngeal microsurgery from March 2004 to December 2006 at Kosin University Hospital. All were women. Voice analysis studies were done before and after laryngeal microsurgery. Five measurements were performed: MPT, Fo, jitter, shimmer and NHR. Results: There was significant improvement in the vocal polyp patients regarding MPT, jitter, shimmer and NHR. Also there was significant improvement in the vocal nodule patients regarding MPT, jitter and shimmer. Conclusion: MPT, jitter, shimmer and NHR will be effective acoustic parameters in documenting the quantitative changes in the vocal polyp patients. MPT, jitter and shimmer will be effective acoustic parameters in documenting the quantitative changes in the vocal nodule patients before and after laryngeal microsurgery.

  • To determine what is the change of pre and postoperative voice and image analysis parameters and correlations between them, videostroboscopy was analyzed in each 18 patients with unilateral vocal cord paralyses or vocal polyps before and after the surgery from November, 1996 to April, 1999. The correlation between acoustic and aerodynamic parameters was investigated. The software-Videolink and $\pi$-View(Mediface Co, Seoul, Korea)-was used in a quantitative analysis. In unilateral vocal cord paralysis, the glottic angle is well correlated with maximum phonation time, jitter and shimmer preoperatively. The postoperative glottic angle is also correlated with preoperative maximum phonation time. In patients with the vocal polyp, the chink is postoperatively decreased, but the size of the chink and the polyp is not correlated with pre and postoperative voice analysis parameters. These findings reveal that glottic an and vocal fold angle are good indicators of e postoperative glottic configuration in unilateral vocal cord paralysis. Vocal fold ratio is also a useful indicator that represents the length of vocal folds. We consider that the computerized analysis through videostroboscopy is one of objective diagnostic methods in many voice disorders if we can measure a distance between the telelaryngoscope and vocal folds.

  • An electroglottography (EGG) was used to investigate the function of the vocal folds during their vibration. In this study, four Korean native speakers and 10 vocal polyp patients were selected. To investigate the dynamic change of EGG waveforms for the three-way distinction of Korean stops, a DSP-Sona graph model 5500, a Rino- Laryngeal stroboscope, a CSL model 4300B and a Laryngograph were used. An EGG Model 4338 was used to exam the vocal polyp of patients' voices during high, low, comfortable pitch production. The purpose of this study is to investigate the characteristics of Korean stop consonants in relation to pitch and to observe laryngeal movement during vocal fold vibration and speech production. The basic data accumulated during this research can be applied in clinical treatment. The results are as follows: on the Korean stop consonants, the aspirated stop is the highest in the GOT and PC1. On the angle of vowel contour, the angle of lenis is smaller than the angle of heavily aspirated and glottalized stops. The fundamental frequency is lowest at the lenis stop, In vocal polyp patients', the low pitch range is smaller than in normal speakers'. The pitch break and the vocal fry were observed. The jitter and OQ value are higher in vocal polyp patients than in those of normal speakers'.

  • Background and Objectives : Vocal fold bowing is an organic voice disorder that is associated with an abnormal structure of the vocal folds whereas vocal fold polyp is a functional voice disorder caused by an abnormal use of the vocal folds. Both types of vocal folds share a common property in that they make one's voice breathy or strained. The purpose of this study is to compare voice from two types of vocal folds and to offer information of clinical importance. Materials and Method: Vocal fold bowing and vocal fold polyp groups consisted of 7 male subjects, respectively. All subjects recorded /a/ in the state of measuring MPT (maximum phonation time), repeating 3 times, by a voice recorder (48 kHz sampling rate; 24 bit quantization). They answered the questions of K-VHI. Time domain parameters (such as perturbation parameters including HNR, Jitter, etc.) were calculated for the whole duration of /a/ and those of the frequency domain were measured in initial 40 ms and stable 40 ms of /a/, respectively. Mann-Whitney V-test was used for the time domain parameters and K-VHI survey, and Wilcoxon signed rank test was applied to the frequency domain parameters (H1, H2, H1-H2). Results: For K-VHI survey and the time domain analysis, there was no significant difference between bowing and polyp group. For frequency domain analysis, H1 and H2 showed a significantly different result between two groups. Vocal fold bowing group has longer duration and lower intensity than that of vocal fold polyp group in the 'aspirated interval', which could be observable prior to ordinary vowel oscillation. Conclusion: Both groups seem to show breathy voice. This could be referred on the basis of the value of H1-H2. The K-VHI survey says that subjects with vocal fold bowing feel more uncomfortable than subjects with vocal fold polyp.

  • Benign vocal fold lesions such as polyps, nodules and edema are known to be caused by vocal trauma such as voice misuse and/or abuse. Even though these lesions are known to be caused by the same etiology, phonotrauma, they show widely different clinical features and different responses to voice therapy. Previous studies suggested that benign vocal fold lesions represent disturbance in the balance of the extracellular matrix(ECM) constituents of the vocal folds. Collagen is one of the major constituents of ECM. Among collagens, fibrillar collagens are most important ones for maintaining the structural integrity. On the basis of gross morphology, vocal polyps wert divided into angiomatous one and edematous one, and nodules were divided into conical one and sessile one. In these four groups, the pattern of distribution of various fibrillar collagens(type 1, 2, 3, 5) was studied by immunohistochemical staining using paraffin embedded tissues. Within each group, differences among collagen subtypes were insignificant. In edematous polyp, collagens were sparsely dispersed in lamina propria by diffuse edema. In angiomatous polyp, collagens were displaced into submucosal layer by hemorrhagic space. In nodules, collagens were stained compactly in lamina propria. Quite different distributions of fibrillar collagens between polyps and nodules are thought to suggest that vocal polyps and nodules are totally different disorders in their pathophysiology.

  • Sarcomatoid carcinomas are biphasic tumors which have surface epithelial changes and an underlying spindle-shaped neoplastic proliferation. A 62-year-old male with hoarseness came to our hospital for evaluation. A single smooth polypoid lesion was detected on his right true vocal fold by larnygoscope. The patient was diagnosed with vocal polyp and treated with surgical excision. Pathology report of the excised specimen was compatible with sarcomatoid carcinoma. Therefore, further surgical resection was performed to secure safety margins. We report a case of a sarcomatoid carcinoma patient who was clinically diagnosed as vocal polyp.

  • Background and Objectives: The 585-nm pulsed dye laser (PDL) has recently been adopted by otolaryngologists because of its epithelial-sparing properties. Many authors have reported the use of PDL for treatment of various vocal cord lesions. This purpose of this study is to examine the effectiveness of 585-nm PDL in the treatment of vocal polyp. Materials and Methods: Eight patients with vocal polyp were treated with 585-nm PDL from Sep. 2006 to Nov. 2006 in Yong-dong Sevrance hospital. 5 of them went through local anesthesia and 3 of them went through general anesthesia. In order to control laser fiber, flexible digital transnasal laryngoscope was applied under local anesthesia and general anesthesia using LMA, and micromanipulator was used under general anesthesia using endotracheal tube. The evaluations of vocal function was done at pre-and postoperation. Results: All patients improved in the perceptual evaluation of voice after PDL surgery. The aerodynamic study revealed that 5 of 8 patients showed improvement in maximal phonation time, and 6 of 8 showed improvement in mean airflow rate during phonation. The acoustic analysis revealed that all patients showed improvement in Jitter and Shimmer, and 7 of 8 showed improvement in noise to harmony ratio. Conclusion: This study demonstrates promising results in the efficacy of 585-nm PDL for the treatment of vocal polyps, and it illustrates a new option for vocal polyp treatment as well as the advantage of PDL surgery.
