  • 이비인후과 영역의 종양중 후두종양은 비교적 흔히 볼 수 있으며, 그 특이한 증상과 간접후두경 및 후두직달경 등으로 조기진단이 가능한 반면에 증상의 경과도 빨라 치명율 역시 높은 것이 사실이다. 이에 저자는 1978년 6월부터 1983 년 2월까지 본 병원에 내원하여 애성 및 후두종양을 발견한 108명의 환자를 임상적 및 병리학적으로 분류하여 문헌적 고찰과 함께 보고하는 바이다.

  • Vocal polyp is one of the representative chronic diseases of vocal folds, and it can be cured by voice therapy and/or laryngeal microsurgery. However, the existing therapeutic methods about vocal polyp are in great demand. The purpose of this study was to evaluate the effect of vocal improvement between laryngeal microsurgery and $SKMVTT^{(R)}$ (Seong-Tae Kim's Multiple Voice Therapy Technique), which was designed by the author. We identified 37 patients, who were diagnosed with unilateral vocal polyp, aged from 21 to 62 years(mean age: 46 years). 21 patients were treated by the $SKMVTT^{(R)}$ and the other 16 patients were only treated by the laryngeal microsurgery. All patients who were treated by the $SKMVTT^{(R)}$, received 12 sessions of treatment, and were evaluated before therapy and after finishing the 12th session. The patients who were treated by laryngeal microsurgery, were evaluated prior to and at least 8 weeks after surgery. The results showed that the $SKMVTT^{(R)}$ produced better results compared to the laryngeal microsurgery alone. The $SKMVTT^{(R)}$ produced better results, especially, at the initial stage of voice therapy compared with those of laryngeal microsurgery. In this study, we can suggest that $SKMVTT^{(R)}$ may be useful in improving the voice qualities of vocal polyp patients. However, more data should be collected and evaluated to be widely used in other clinics.

  • Background and Objectives : Vocal polyps and nodules are representative chronic benign laryngeal disease. Treatment options for vocal polyp and nodule in general include voice therapy or laryngeal microsurgery. The purpose of this study was to analyze voice results before and after laryngeal microsurgery. Materials and Method: Vocal polyp and vocal nodule patients were treated by laryngeal microsurgery from March 2004 to December 2006 at Kosin University Hospital. All were women. Voice analysis studies were done before and after laryngeal microsurgery. Five measurements were performed: MPT, Fo, jitter, shimmer and NHR. Results: There was significant improvement in the vocal polyp patients regarding MPT, jitter, shimmer and NHR. Also there was significant improvement in the vocal nodule patients regarding MPT, jitter and shimmer. Conclusion: MPT, jitter, shimmer and NHR will be effective acoustic parameters in documenting the quantitative changes in the vocal polyp patients. MPT, jitter and shimmer will be effective acoustic parameters in documenting the quantitative changes in the vocal nodule patients before and after laryngeal microsurgery.

  • Vocal cord polyps are generally removed using a direct laryngoscope and surgical microscope. In some case of laryngeal microsurgery, laryngeal exposure with surgical microscope is difficult because of severalfactors. We experienced a case of vocal polyp with difficult laryngeal exposure in a 56 year old male patient. The vocal cord polyp was removed successfully through endoscopic approach.

  • Background and Objectives:The purpose of this study is to find features in acoustics and to learn useful features of parameters in order to distinguish laryngeal diseases through many acoustic variables. Materials and Methods:The subjects of this study were 125-male patients who had been diagnosed with vocal nodule, vocal polyp, vocal cyst, Reinke's edema, leukoplakia. To research the features of each disease in acoustics, they are measured 34 parameters by using MDVP. Results:It is clear that in order to see a meaning result when distinguishing laryngeal diseases, $F_0$, $MF_0$, $T_0$, Fhi, Flo, PER variables are significant (p<.05). It means that variables related to fundamental frequency are important to anticipate which group will be diagnosed with Reinke's edema and leukoplakia. vAm had an effect on getting a significant result in terms of amplitude perturbation parameters, which is useful to distinguish between laryngeal polyp/cyst and other laryngeal disease (p<.05). ATRI made a significant result in related to tremor parameters, which is useful to distinguish between laryngeal polyp and other laryngeal disease (p<.05). Conclusion:$F_0$, $MF_0$, $T_0$, Fhi, Flo, PER, vAm, ATRI might be meaningful parameters distinguishing pathologic from benign laryngeal diseases. Especially, the vAm and ATRI are an important factor when forecasting which group would be diagnosed with vocal polyp.

  • Indications of fiberoptic laryngeal laser surgery (FLS) procedure have broadened by the development of flexible fiberoptic endoscopes and flexible laser systems. FLS procedure performed under local anesthesia and it is the unique value of FLS. The surgery can be performed on patients who are impossible to undergo general anesthesia and difficult to be exposed by laryngeal microsurgery. Main indication of FLS procedure was small to moderate sized hemorrhagic vocal polyp, but we experienced a case of huge vocal polyp with difficult laryngeal exposure treated by FLS procedure under local anesthesia. The vocal polyp was removed successfully without vocal fold scar through fiberoptic laryngeal laser surgery under local anesthesia.

  • Background and Objectives : Vocal polyps are caused by inflammation induced by stress or irritation. Many patients with vocal polyps complain voice discomfort. For vocal polyps, surgery such as laryngeal microsurgery has been the mainstay of management. We analyzed the clinical features of vocal polyps, and how the size and location of vocal polyps affect the outcomes of surgery. Methods : We retrospectively reviewed 42 patients from March 2014 to December 2015, who were diagnosed as unilateral single vocal polyp. When we operated on a vocal polyp with laryngeal microscopy, we measured their size and location. The quality of voice was evaluated by GRABS scale, jitter, shimmer, NHR (noise to harmonic ratio), MPT (maximum phonation time), and VHI (voice handicap index) before operation and 4 weeks after operation. Results : When we divided the patients into large-sized vocal polyp group (the longest length >3 mm) and small-sized vocal polyp group (the longest length ${\leq}3mm$), all parameter differences tend to be greater at large sized vocal polyp. However, these differences were not statistically significant (p>0.05). When we divided into two groups depending on the volume of vocal polyp, no distinct tendency was found. When we compared the location (anterior, mid and posterior) of vocal polyp with the improvement of voice quality, more change was found at mid portion vocal polyp, except the difference of VHI. However, these differences were also not statistically significant (p>0.05). Conclusion : All parameter differences tend to be greater at large vocal polyp and polyp of the mid location.

  • An electroglottography (EGG) was used to investigate the function of the vocal folds during their vibration. In this study, four Korean native speakers and 10 vocal polyp patients were selected. To investigate the dynamic change of EGG waveforms for the three-way distinction of Korean stops, a DSP-Sona graph model 5500, a Rino- Laryngeal stroboscope, a CSL model 4300B and a Laryngograph were used. An EGG Model 4338 was used to exam the vocal polyp of patients' voices during high, low, comfortable pitch production. The purpose of this study is to investigate the characteristics of Korean stop consonants in relation to pitch and to observe laryngeal movement during vocal fold vibration and speech production. The basic data accumulated during this research can be applied in clinical treatment. The results are as follows: on the Korean stop consonants, the aspirated stop is the highest in the GOT and PC1. On the angle of vowel contour, the angle of lenis is smaller than the angle of heavily aspirated and glottalized stops. The fundamental frequency is lowest at the lenis stop, In vocal polyp patients', the low pitch range is smaller than in normal speakers'. The pitch break and the vocal fry were observed. The jitter and OQ value are higher in vocal polyp patients than in those of normal speakers'.

  • 후두의 Microsurgery는 육안으로 관찰할 수 없는 작은 병변을 그 초기에 발견하고 치료하는데 유익하며 이는 근년에 와서 Scale(1960), Kleinsasser(1964) 등에 의해 개발되었고 Saito 및 많은 임상가들에 의해 추시된 바 있으며, 노도 그의 경험 20여례에 대하여 상세한 보고를 하였다. 귀수술에 사용되는 zeiss 수술현미경의 대물 lens 위에 보조 lens를 장치하여 충분한 작동거리를 확보할 수 있으며, 나아가 fiber optics에 의한 suspeasion laryngoscope로써 시야를 밝게 할 수 있으며, 따라서 정확한 진단 및 세밀한 수술을 할 수 있다. 즉 점막상피내암, 후두점막질환, 성대 polyp, nodule및 cyst 등에 대한 현대적 진단과 치료법이기도 하다. 저자 등은 전남의대 부속병원 이비인후과를 내원한 후두질환 환자중 선택적으로 suspension laryngomicr-oscopy를 이용하여 진단 및 외과적 적출을 시행한 11례(성대 polyp; 4례, 유두종; 4례, 진성대 및 가성대의 web형성; 1례, 후두외상; 1례, 후두상피세포암: 1례)를 경험하였기에 우선 예보를 하는 바이며, 앞으로 지속해서 많은 경험증례를 분석검시하여 보고하겠다.
