Laryngeal stroboscopy is a important clinical tool in the diagnosis and evaluation of patients with voice disorders. Stroboscopic parameters evaluated during examination include symmetry, periodicity, glottic losure, amplitude, mucosal wave, and amplitude. Stroboscopy can provide useful information on glottal closure patterns in patient with/without vocal fold pathology and this paper describes the stroboscopic findings of the laryngeal pathologic lesions.

An irritable larynx syndrome is characterized by a sudden episodic dyspnea and dysphonia that is difficult to diagnose, and patients are often treated unnecessarily and/or too much. A correct diagnosis can be made by monitoring the larynx closing in the reversed direction during inhalation and posterior chink with videolaryngoscopy and by measuring a decrease in air flow volume during inhalation with a lung function test. Patients can be effectively treated with thorough differential diagnosis. Medications targeting precipitating factors, physical therapy sessions to improve abnormal larynx movement, counseling to reduce patients'anxiety rising from dyspnea, and etc. can effectively alleviate symptoms.

Voice is a physical phenomenon, generated by vocal fold and expiratory airflow. Dysphonia should come from abnormal vocal fold and airflow. Occassionally larynx looks normal in show, but it is actually not. There should be undetected structural or functional abnormalities. So when ENT doctors face dysphonia patients who looks normal larynx, should make a diagnosis through close observation. In this review article we present some dysphonia diseases which looks normal larynx. For example vocal fatigue, vocal fold paresis, posterior glottic diastasis, muscle tension dysphonia and psychogenic dysphonia.

Amyloidosis is a diverse group of disorders that share the deposition of amyloid protein in various extracellular tissues. Systemic amyloidosis may involve any body part and about 9-15% of it is localized. In the head and neck, the larynx is known as most common involved site. A histological diagnosis of amyloidosis is necessary to establish a definite diagnosis. Conservative surgery can be done for relieved airway obstruction or restored voice. We present three cases of patients with laryngeal amyloidosis that was treated with laryngeal microscopic surgery with laser.

Bilateral vocal cord palsy (BVCP) present a challenging condition which result from various etiologies including iatrogenic recurrent laryngeal nerve injury, progressive neurological disorder, intubation, trauma, tumor and idiopathic cause. Careful history taking, laryngoscopic evaluation, laryngeal EMG, and imaging studies are helpful for providing a precise diagnosis and planning appropriate treatment. BVCP causes airway restriction and not vocal dysfunction. In patients with BVFP, treatment is directed at maximizing the airway, while attempting to limit the negative effects of treatment on vocal function. A variety of surgical procedures are available for mangement of BVCP. The most conservative, limited procedure should be selected initially, and then further surgery and more extensive surgery can be tailored to the patient's airway and voice needs. This review will address the etiology, diagnosis, and managements of BVCP.

Background and Objective : Laryngeal microscopic surgery (LMS) is popular method to treat for vocal polyp. There is not always the improvement of the voice after operation. Many methods have been developed for better outcome of the surgery. The purpose of this study is to investigate the effect of the triamcinolone injection at vocal cord during LMS. Materials and Methods : The medical records of 28 patients, received LMS under diagnosis of vocal polyp, were retrospectively reviewed. The patients were divided into two groups depending on whether triamcinolone injected or not (case group : Triamcinolone-injected group, control group : Triamcinolone-not injected group). The quality of voice was evaluated by GRBAS scale, fundamental frequency (Fo), jitter, shimmer and NHR (Noise to harmonic ratio) at previous operation, 4 weeks after operation, 8 weeks after operation. Each voice analysis factor was compared between case group and control group by Independent t-test. Results : The mean differences of each voice analysis factor. The mean difference of Jitter, Shimmer, NHR in case group were lower than in control group, and mean difference of GRBAS scale in case group were higher than in control group. These differences were not significant (p>0.05). Conclusion : Though there was a tendency of better voice outcome in patients of triamcinolone-injection, it may not be concluded that the triamcinolone injection is helpful for better voice outcome in surgery of vocal polyp due to statistical insignificance.

In order to the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. The inspection on the individual characteristic factor was analyzed the face colour, inspection of tongue. The auscultation and olfaction on the individual characteristic factor was analyzed the 25 types by the five-voice (五音) in Huang Di Nei Jing (黃帝內經). As the results, the individual characteristic factor is very important item of the four methods of diagnosis and the differentiation of syndromes. And Therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

Voice can be widely used to classify the four constitution types and to recognize one's health condition from extracting meaningful features as physical quantity in traditional Korean medicine or Western medicine. In this paper, we proposed the method to update the standard operating procedure (SOP) to acquire and record voices for extracting stable vocal features since they are sensitive to the variation of a subject's utterance. At first, we obtained pitch frequencies from vowels and the sentence and intensity form the sentence as features with voices acquired under subjects' utterance conditions and then the deviation ratios of features from median values according to the utterance conditions were obtained and the condition to minimize the ratio was selected as a new SOP. As a result, we decided the SOP for a subject to utter vowels with the length of 2s~1s and sentences with over 2s interval between them after practice, in consideration of the deviation and qualitative requirements. Stable voice features obtained from updated SOP produce accurate diagnosis, which will be developed and simplified for using in the u-Healthcare system of personalized medicine.

Background and Purpose The purpose of this study was to confirm that what symptoms are adequated indicator in the Gi-Deficiency patients. Methods In the time period July. 2005 to Sep. 2006, 136 patients with a first-ever stroke admitted in the department of Internal Medicine of Daejeon University Oriental Medical Hospital in Daejeon city, Wonkwang Oriental Medical Hospital in Iksan, JeonJu city were included. Patients were hospitalized within 3 months after the onset of stroke. Stroke patients had been interviewed by resident who studied standard operation procedures in Fundamental Study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. Gi-deficiency patients was confirmed by medical specialist diagnosis, resident diagnosis, case report form analysis without a dissenting voice. Results Gi deficiency group included 23 case, Non Gi deficiency group 47 case out of 136 patients. Fatigue, weakness purse, somnolence, low voice, difficulty of uprise, pale face, pale tongue were higher among Gi deficiency group. Gi deficiency and Non Gi deficiency patients do not significantly differ in white coating tongue, light-red tongue, poor appetite, frequent sweating, teeth printed tongue. Conclusions This study was insufficiency because sample size very small. More data from prospective cohort studies will help to Korean Standard Differentiation of the Symptoms and Signs for the stroke.
