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: Voice therapy using nasal stimulus sounds seems to facilitate a more easily produced, often better-sounding voice in benign vocal fold lesions. This study was designed (1) to determine whether nasalance score was different in patients with or without vocal fold masses, (2) to test if nasalance score was different from each disease group, and (3) to determine the difference between the normal and the disease group according to the reading materials. SUBJECTS AND METHOD: One hundred and sixty-eight subjects were evaluated. Each subject received a complete otolaryngological evaluation including physical examination, videostrobolaryngoscopy, objective voice measures, and evaluation by a speech-language pathologist. The control group consisted of 48 subjects with no nasal and vocal fold pathology. Subjects were evaluated on a nasometric assessment with three passages of oral-nasal sound. RESULTS: All disease groups demonstrated lower nasalance scores than the control group. CONCLUSION: There are significant differences in the nasalance scores between each disease group and the control group. Differences were also found according to the reading materials.

BACKGROUND: Immobile vocal fold or folds result from neuromuscular pathology and/or mechanical fixation of cricoarytenoid joint. Electrophysiological investigation is indispensible in the diagnosis and treatment of laryngeal mobility disorders. However, laryngeal electrodiagnosis has been rarely performed clinically, not to mention nerve conduction study (NCS). It is well understood that needle EMG and NCS are complementary, and they should be performed together for reliable evaluation of neuromuscular system. OBJECTIVES: The author intended to present the methods and clinical application of laryngeal electrodiagnosis. MATERIALS AND METHODS: Laryngeal electrodiagnosis including needle EMG and NCS was performed in the patient with bilaterally immobile vocal folds. CONCLUSION: Electrodiagnosis is inevitable in the diagnosis and treatment of larygeal mobility disorders;the differentiation of neurogenic lesion from mechanical fixation, the diagnosis of the site of nerve lesion, and the estimation of the degrees of injuries. Furthermore by performing NCS, we can have the objective prognosticator, and therefore can take the best timing and choice of surgical intervention in the management of laryngeal mobility disorders.

BACKGROUND AND OBJECTIVE: Vocal cord palsy is a complex disorder which may result from numerous causes. Laryngeal electromyography is a valuable adjunct in the study of vocal cord dysfunction. It yields objective and reproducible data, and may establish the pathophysiology and prognosis of laryngeal nerve pathology. We investigated the clinical usefullness of laryngeal electromyography for patients with vocal cord palsy. MATERIAL & METHOD: Laryngeal EMG was performed for 35 patients diagnosed as vocal cord palsy. RESULTS: We defined complete denervation when electrical silence, fibrillation potential or positive sharp waves were seen. We defined partial denervation when motor unit potential with low amplitude and low frequency was seen. We planned treatment modality according to the laryngeal EMG findings. In case of complete denervation, phonosurgery was recommended, whereas voice therapy and observation were recommended when partial denervation was noted. CONCLUSION: Laryngeal EMG is clinically valuable for the evaluation of vocal cord palsy and can serve as a guideline for determining the treatment plan. It is also useful in anticipating the prognosis of laryngeal nerve palsy.

Published reports about polyps of larynx at the ventricular bands are extremely rare. The first symptom of this case presents recurrent hemoptysis. The video laryngoscope demonstrated that a smooth-faced and hyperemic polypoid lesion was found in the anterior part of the right false vocal cord, close to laryngeal surface of epiglottis. Postoperative pathological report revealed that the mass was a vascular polyp.

OBJECTIVE: To use the maximum loudest phonation time (MLPT) on evaluation of unilateral vocal fold paralysis. METHOD: The MLPT, maximum comfortable phonation time (MCPT) and maximum phonation time (MPT) were tested and collected in 17 patients with unilateral vocal fold paralysis. The data of ratio value of MLPT to MCPT also was collected. The stroboscopy, perceptual measures and self-questionnaire also were used in evaluation of vocal fold and voice in all patients. Correlation coefficients were used as measures of agreement. RESULT: MLPT was (5.0 +/- 4.0)s, MCPT was (5.4 +/- 4.1)s, and MPT was (6.1 +/- 4.5)s in patients. The MPT was composed of MLPT in 4 patients and MCPT in 13 patients. The MLPT/MCPTa was 1.08 +/- 0.47. MLPT was positively correlated with MCPT and MPT, respectively (r = 0.679, P < 0.01; r = 0.878, P < 0.01), and MCPT also was positively correlated with MPT (r = 0.993, P < 0.01). MLPT, MCPT and MPT was negatively correlated with G value which was from GRBAS scale, respectively (r = -0.620, P < 0.05; r = -0.564, P < 0.05; r = -0.665, P < 0.05). The MLPT/MCPTa was positively correlated with the value of question 4 from self-questionnaire (r = 0.534, P < 0.05). MLPT, MCPT or MPT had no correlation with self-questionnaire, GRBAS perceptual evaluation or stroboscopy measures significantly. CONCLUSION MLPT, MCPT or MPT can be used for evaluation of aerodynamic measures in unilateral vocal fold paralysis. The MLPT may be easiest to operate in clinic. The MLPT/MCPTa ratio can assess dysphagia in unilateral vocal fold paralysis patients.
