The clinical study of 183 cases of laryngeal mass was observed and 88 cases of vocal nodule and polyp which is confirmed histopathologically, were clinically classified into 30 cases of vocal nodule, 48 cases of localized vocal polyp, 10 cases of diffuse vocal polyp, and the following results of microscopic examination were obtained. I. The clinical study of laryngeal mass 1. Among total cases of 183, vocal nodule is 82(45%) vocal polyp 53(29%) postintubation granuloma 3(1%) laryngeal papilloma 18(10%) tuberculosis 2(1%) cancer 25(14%). 2.

In the past history, certain relationship with smoking is noted in cancer (40%) and tuberculosis(50%) and the history of frequent attack of URI is in papilloma(33%). 10. In occupation, certain statistical significance was not noted. II. The histopathological study of vocal nodule and polyp. 1. Most polyps and nodules were covered with stratified squamous epithelium, but focal hyperkeratosis, parakeratosis, acanthosis and atrophy were rather frequently observed. Hyperkeratosis and acanthosis was most frequently seen.

성대내전이 불완전하거나 양측 성대간의 간격이 넓은 경우 애성이나 흡인의 문제를 해결하기 위하여 과거에는 paraffin, teflon, bovine collagen 등을 성대에 주입하여 왔으나 이물반응이나 육아종의 형성 둥이 문제가 되고 있어, 최근에는 자신의 지방이나 피부에서 추출한 교원질을 이용한 연구 및 사례가 보고되고 있다. 그 중 자가지방은 시술이 간편하고, 비용이 적게 드는 장점이 있으나, 흡수율이 높다는 문제점이 지적되고 있다. (중략)

The etiology of vocal fold granuloma was identified : post-endotracheal intubation, vocal abuse, acid reflux and idiopathic. The identification of the cause or causal factor is important, since the treatment must be fundamental directed at them. Treatment have included voice therapy and antireflux measures. Surgical excision is considered in patients who do not respond to medical management. In this study, a case of vocal fold granuloma resolved who underwent injection of the affected vocal fold. Botulinum toxin type A is probably successful by decreasing the strength during adduction in the arytenoid region which, when very intense, would perpetuate the granuloma. Localized injection of this neurotoxin is promising both as an initial treatment and as an alternative treatment in patients who do not respond to standard therapy.

Endotracheal intubation is common practice for either general anesthesia or keeping artificial airway in various conditions. Despite of its great usefulness, however, laryngeal edema, ulceration, and granuloma are occasionally developed following endotracheal intubation as posttraumatic complications. Vocal cord paralysis is also rarely developed. Recently we experienced a case of left vocal cord paralysis with accompanying hoarseness following endotracheal general anesthesia for appendectomy. The symptoms of hoarseness and sore throat developed immediately after the general anesthesia. Periodic check revealed gradual return to normal function of the paralyzed cord with the complete function about 3 months after the anesthesia.

성대결절, 폴립, 부종 등은 성대의 남용이나 과용등의 성대손상이 그 공통된 주된 원인으로 거론되고 있다. 하지만 음성치료를 비롯한 보존적 치료에 대한 반응이 서로 상이하며, H＆E 염색을 이용한 병리조직학적인 감별이 곤란하여 진단에 혼돈이 있으며, 치료의 방침을 결정하거나 예후를 예측함에 있어서도 어려움이 있다. 양성성대질환은 기저막부 위와 세포외 간질에 주된 변화가 발생함이 알려져 있고, collagen type IV의 발현양상이 성대결절과 폴립에서 서로 다름에 대하여는 보고된 바 있으나 기타 점막하층의 골격유지를 주기능으로 하는 대표적 세포외간질인 collagen subtype에 대하여는 아직 보고된 바가 없는 실정이다. Collagen 발현의 차이를 연구하는 것은 상기질환의 병인을 이해하고 질환분류의 guideline을 제시하며 나아가 적절한 치료방범을 제시하는 데에 큰 의미가 있을 것으로 기대된다. Paraffin에 고정되어 있는 5례 이상씩의 성대결절과 성대폴립, 육아 종 및 라인케씨 부종 조직을 collagen type I부터 VII에 대하여 peroxidase kit를 사용하여 염색한 후 각 군간에 collagen 분포양상과 발현정도에 차이가 있는가 비교하였다.

Background and Objectives: Vocal cord granuloma is a exophytic inflammatory mass and caused by gastroesophageal reflux, voice abuse, endotracheal intubation. There has been a controversy in the treatment of vocal cord granuloma. Our aim of study is to know the clinical characteristics and the results of surgical management for vocal cord granuloma. Materials and Methods: We have reviewed and analyzed medical records of 55 patients who were diagnosed and surgically treated as vocal cord granuloma in Asan medical center from 1997 to 2005 retrospectively. Results: 25 cases were intubation granuloma and 30 cases were contact granuloma. In intubation granuloma, the clinical manifestation was hoarseness(70%), foreign body sensation(44%), chronic cough(21%). In contact granuloma, the clinical manifestation was hoarseness(67%), foreign body sensation(60%), throat clearing(21%). The recurrence rate after surgery was 8% in intubation granuloma and 33% in contact granuloma. Mean recurrence time was 4.1months in intubation granuloma and 3.2months in contact granuloma. Conclusion: Although there is no significant difference, recurrence rate after surgery was high in contact granuloma compared to intubation granuloma(p=0.125). Although this study is retrospective, surgical management must be considered in resolving diagnostic doubt, treating airway obstruction, and failure in conservative treatments.

In the field of otolaryngology-head and neck surgery, botulinum toxins are widely used for the treatment of spasmodic dysphonia and vocal tremors. Recently, the applications of botulinum toxin have gradually expanded with time, to include vocal fold granuloma, mutational falsetto, bilateral vocal cord paralysis, and chemical reduction for arytenoid dislocation as an adjunctive modality. According to a nation-wide multicenter study conducted by the Korean Society of Laryngology, Phoniatrics and Logopedics for treatment modality of contact granuloma, among the various treatment modalities, botulinum toxin injection showed the highest response rate and lowest recurrence rate in both primary and refractory cases. Therefore, botulinum toxin could be reserved as a second-line treatment for contact granuloma in which the first treatment was not effective, but also could be used as a first-line treatment depending on the patient's and institution's situation. For recalcitrant nodules, injection of botulinum toxin into the bilateral thyroarytenoid muscle will reduce glottal contact force and result in a forceful chemical voice rest. In special situations, botulinum toxin injection could be one of the alternative treatment options for recalcitrant vocal nodules.

Sarcoidosis, a multisystemic granulomatous disorder of unknown causes, which presents with bilateral hilar adenopathy, pulmonary infiltration, and cutaneous, ocular, bones, and nervous and reticuloendothelial systems involvement, commonly involves young adults of both sexes. Herein, the case of a 70-year-old male, with progressive hoarseness of two weeks' duration and mild dyspnea, is reported. A fiberoptic bronchoscopy, performed to investigate the hoarseness, revealed paralysis of the left vocal cord, but with no other local abnormality. Two nodules, as pathologic findings, showed noncaseating epithelioid cell granulomas. We note a rare case of sarcoidosis, with vocal cord palsy, in Korea.

Pyogenic granuloma is very uncommon disease. It is a benign, elevated, and capillary-rich lesion occupying on the skin and mucous membranes, and is a reactive lesion, an overgrowth of granulation tissue. And this lesion may grow rapidly and can recur frequently. Pyogenic granuloma usually occurs on the lip, tongue, oral mucosa, and nasal mucosa. But, pyogenic granuloma of vocal cords is very rare. Recently, we experienced a case of pyogenic granuloma of a 48-year-old man who had been presented with hoarseness for 3 months. He was diagnosed pyogenic granuloma after laryngeal microscopic surgery. So we report this rare case with review of literatures.

Background and Objectives : This study evaluated the efficacy of combination therapy of proton pump inhibitor (PPI) and steroid inhaler (SI), with or without botulinum toxin injection (BTX) for contact granuloma. Subjects and Methods : Fourteen contact granuloma patients were enrolled in this study. Combination therapy of PPI and SI were used for the first line treatment. When combination therapy was not effective, BTX was performed as the second method. Treatment results were recorded as responsible or non-responsible. Farwell grade, size, history of voice abuse, gender, and reflux finding score (RFS) were compared between responsible group and non-responsible group. Results : Initial response rate was 28.6% after treatment of PPI and SI. BTX was performed on three un-responsible patients. After BTX injection, three patients had complete remission of granuloma. Final response rate was 50.0%. Un-responsible group had significantly higher RFS than responsible group. Conclusion : The efficacy of PPI and SI was limited for contact granuloma in this study. Botulium toxin injection was recommended in early phase when PPI and SI did not effective for contact granuloma. Prospective studies evaluating the effects of PPI and SI are warranted.
