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.

음성외과는 발성기능를 취급하는 기능외과이기 때문에 수술적응의 결정 수술효과의 판정 수술성적의 비교를 위하여 발성기능의 검사가 필요하다. 청력을 취급하는 수술에서 청력검사가 필요한 것과 같다. 연자는 구유미대학 이비인후과를 방문한 각종후두환자(56례 즉Recurrent laryngeal nerve paralysis, polyp. polipoid vocal cord. sulcus vocalis, Laryngeal cancer, Benign mass, Epitherial hypertrophy. 등에서 발성지적시간, 폐활량/담성지적시간, 평균호기유율 및 후두 Stroboscopy 검사를 시행하여 다음과같은 결과를 얻었다. 1) 성대의 편측성병변은 35례(62.5%)이고 양측성병변은 21례(37.5%)로 편측성병변이 많았다. 2) 성별로는 남성이 39례(69.8%) 여성이 17례(30.2%)로 남성이 많았다. 3) 발성지적시간은 10초이하가 26례(46.4%) 10초이상이 30례(53.6%)이였다. 4) 폐활양/발성지적시간은 300m1/sec이하가 33례(58.9%) 300m1/sec이상이 23례(41.1%)이였다. 5) 평균호기류율은 300m1/sec이하가 37례(66.1%)300ml/sec 이상이 19례(33.9%)이였다. 6) 후두 stroboscopy 검사에서 성대의 대칭성, 규칙성, 진폭, 점막파동 및 성문패쇄에 대해서 관찰하였다. 7) 후두수술전후의 음성검사와 stroboscopy 검사의 비교는 수술후의 성적이 매우 좋다.
