Amyotrophic lateral sclerosis Is an unusual pattern of distal muscular atrophy with permanent bulbar sign. Vocal fold paralysis and velopharyngeal insufficiency(VPI) due to soft palate paralysis Is occasionally associated with distal muscular atrophy. Recently we experienced a case of amyotrophic lateral sclerosis whose symptom was initially expressed with hoarseness and VPI. So we report a case with review of literature.

Vocal fold paralysis continues to be a dominant topic in laryngology. This review article discusses the management principle of patients suffering from unilateral vocal fold paralysis. There are currently some main methods ; voice therapy ; injection laryngoplasty ; laryngeal framework surgery ; reinnervation procedures.

최근 전신마취의 발달로 외과영역에서는 괄목할만한 수술적 진전을 보여 왔으나, 이에 못지 않게 전신마취에 의한 여러 가지 합병증의 보고가 늘고 있다. 특히 이비인후과영역에서는 술후 뚜렷한 원인없이 사성 및 호흡곤란 등을 호소하는 환자들을 종종 접하게 되며, 추정할 수 있는 유인으로는 대개 후두 및 기관점막의 염증, 후두결절, 후두육아종 등이 대부분이나 때로 매우 희귀하지만 원인 불명의 성대마비로 인한 경우도 있다. 저자는 최근 술전에 전혀 후두증상이 없었던 환자로서 기관내 삽관마취하 이하선 혼합종수술후에 속발한 일측성 반회신경마비례를 경험하였기에 문헌적 고찰과 함께 보고하고자 한다.

The laryngeal framework surgery (LFS) is an operation to correct the position and tension of the vocal cords by changing the laryngeal cartilage and muscles. LFS such as type 1 thyroplasty, arytenoid adduction, and arytenopexy is performed to improve the voice of patients with unilateral vocal cord paralysis. It is known that the voice improvement effect of LFS in patients with unilateral vocal cord paralysis is excellent and lasts for a long time. LFS can also be operated under local anesthesia. Complications are not common, however, severe complications like airway obstruction could occur after the operation. Recently, several other attempts to modify the traditional surgical method have been reported. This review is intended to be helpful in understanding the characteristics and changes in laryngeal framework surgery.

Purpose: There are a few case reports on asymmetric vocal cord uptake on FDG-PET in patients with unilateral vocal cord paralysis, which could be a potential pitfall in the interpretation of FDG-PET images. We evaluated the metabolic activity of laryngeal muscles of patients with unilateral vocal cord paralysis in comparison to normal controls during both speech and silence. Methods: Eleven patients with unilateral vocal cord palsy (thyroldectomy=7, lung cancer=1, others=3) and 12 normal controls underwent FDG-PET with usual protocol. They were divided into two groups respectively; one group read books aloud for 20 minutes (phonation group) and the other kept silence (non-phonation groups) after FDG injection. Recent neck CT scan were co-registered with FDG-PET to produce PET-CT fusion images to elaborate small laryngeal muscles. Results: In patients with unilateral vocal cord palsy, contralateral non-paralyzed vocal cord showed hypermetabolism mainly on thyroarytenoid muscle, more intensely with phonation group ($SUV=5.88{\pm}2.65$) than with non-phonation group ($SUV=2.30{\pm}0.39$). Normal control subjects showed hypermetabolism ($3.68{\pm}0.96$) in interarytenoid muscle and symmetric mild hypermetabolism in both lateral cricoarytenoid muscles in only phonation group. Conclusion: FDG-PET with fusion images using CT scan in patients with unilateral vocal cord paralysis showed hypermetabolism of contralateral non-paralyzed thyroarytenoid muscle, suggesting compensatory action during phonation. Phonation durung FDG PET study enhanced FDG uptake on different laryngeal muscles between patients with unilateral vocal cord paralysis and normal subjects.
