Background and Objectives : The effect of palliative injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients on voice and swallowing function is uncertain and there are few previous studies of its suitability, benefits as a palliative treatment option. The purpose of this study is to confirm the objective results of voice and swallowing function after palliative office-based hyaluronic acid injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients. Materials and Method : 36 patients who had unilateral vocal cord paralysis from non-thyroidal, extralaryngeal neoplasms were included in this study. To evaluate the clinical outcome, we analyzed perceptual GRBAS grading, acoustic analysis, aerodynamic study, Electroglottography (EGG), Voice Handicap Index (VHI-30) about voice function and disability rating scale (DRS), gastric tube dependency, aspiration pneumonia about swallowing function and 36-Item Short Form Survey version 2 (SF-36v2) about quality of life. Results : In GRBAS scale, G (p<0.001), R (p=0.004), B (p=0.001), A (p=0.011), and S (p=0.007) showed significant improvement. Jitter, shimmer, speaking fundamental frequency, maximal phonation time, VHI-30, DRS score, gastric tube dependency, aspiration pneumonia, and SF-36v2 were significantly improved after injection (p=0.016, p=0.011, p=0.045, p=0.005, p<0.001, p<0.001 p=0.003, p<0.001, and p<0.001 respectively). Conclusion : From this study we concluded office-based hyaluronic acid injection can be used as a useful palliative treatment option in cancer-related ill patients with unilateral vocal cord paralysis. Palliative hyaluronic acid injection laryngoplasty avoids the need for tube feeding, thus reducing the risk of aspiration pneumonia. These outcomes are accompanied by significant improvement in voice quality.

Evaluating the patient's voice before thyroidectomy is useful for the purpose of identifying patients with vocal cord paralysis without symptoms, identifying other patient's voice abnormalities, and whether it is related to voice disorders that may occur after surgery. Also voice evaluation after thyroid surgery is helpful in diagnosis, treatment, and rehabilitation and follow-up of voice disorders that occur without clear nerve damage after thyroidectomy. And it is helpful for rapid recovery through active early rehabilitation treatment for patients who complain of speech impairment without paralysis. In particular, neck exercise can improve the adhesion of the surgical site and increase the range of motion of the neck as well as improve subjective neck discomfort. In addition, hearing, voice and breathing functions should be improved, and voice hygiene education and counseling should be provided. Vocal cord injection is the first treatment option for unilateral vocal cord palsy. By establishing a protocol for voice disorders before and after thyroid surgery and providing appropriate treatment, the quality of life of patients can be improved.

The tests related to air usage are valuable for evaluating phonatory function of clinical cases having glottic incompetence. Measurement of mean air flow rate, maximum phonation time and phonation quotient are important test for voice disorder. Stroboscopy is very useful for clinical evaluation of abnormality in the mode of vocal cord vibration. Author obtained following clinical result from 56 cases of laryngeal disorders in Kurume medical school in Japan. 1) Unilateral laryngeal lesions, are 35 cases (62.5%) and bilateral laryngeal lesions are 21 cases (37.5%). 2) Sex ratio is 39 cases (69.8%) of male and 17 cases (30.2%) of female. 3) In maximum phonation time below 10 seconds are 26 cases (46.4%) and above 10 seconds are 30 cases (53.6%). 4) In phonation quotient below 300 ml/sec are 33cases (58.9%). and above 300ml/sec are 23 cases (41.0%). 5) In mean air flow rate below 300ml/sec are 37 cases (66.1%) and above 300ml/sec are 19 cases (33.9%). 6) Symmetry of vibratory movement of the vocal cord, regularity of vibration, amplitude of vibration, wave on the mucosa and glottic closures are observed by stroboscopic examination. 7) Postoperative voice test and stroboscopic examination revealed good result in compare pre-operation with post-operation.
