Introduction: 585 nm Pulsed dye laser (PDL) laryngeal surgery is based on the photodynamic characteristics of selective photothermolysis and photoangiolysis and recently considered to be the treatment for a variety of benign laryngeal disease. Objective: To review the indications and outcome of office-based 585nm PDL surgery and summarize new developments. Method: Retrospective study involving 402 patients was performed, The PDL surgery could be applied to various laryngeal diseases such as laryngeal papilloma, vocal fold dysplasia, laryngeal granuloma, vocal polyp, capillarectasia, scarred vocal fold and sulcus vocalis. Results : The physiologic properties of the vascular specificity of PDL provide many advantages and appear to be effective for laryngeal treatment. The PDL resulted in precise, selective coagulation of the microvasculature without damage to the surrounding tissue. Therefore PDL surgery is safe and effective for office-based treatment of benign laryngeal disease and for all patients regardless of their overall medical condition. Conclusion: PDL surgery provides potential benefits and advantage for treating common benign laryngeal disease.

Laryngomalacia is the most common congenital anomaly that causes inspiratory stridor and airway obstruction in the newborn. Symptoms begin to appear after weeks of age, become worse at 4-8 months, improve between 8-12 months, and usually heal naturally at 12-18 months. Despite these common natural processes, the symptoms of the disease can be very diverse and, in severe cases, require surgical treatment. The diagnosis can be made by suspicion of clinical symptoms and direct observation of the larynx with the spontaneous breathing of the child. Typical laryngeal features include omega-shaped epiglottis, retroflexed epiglottis, short aryepiglottic fold, poor visualization of the vocal folds, and edema of the posterior glottis, including inspiratory supra-arytenoid tissue prolapse. In this review, we discuss the classification and treatment based on symptoms and laryngoscopic findings in patients with laryngomalacia.

성문과 성문하부의 기도 폐쇄는 위치 정도 원인 기간 등은 환자에 따라 다르고 그 치료방법 역시 다양하다. 주 원인으로는 기관내 삽관, 각종 외상 및 화상 등 을 들 수 있다. 이러한 질환의 치료 목적은, 기관내 튜브나 기관 캐뉼러 를 통하지 않고 비강을 통하여 자연스럽게 호흡할 수 있도록 기도를 유지 하면서 발성이 가능하고 기고 흡인 없이 연하가 가능하도록 하며 기침 반사가 원활하게 되도록 하는데 있다. 치료목적의 달성을 위하여 협착의 경우, 단계 즉 초기 단계 또는 성숙단계 여부, 위치, 정도, 범위 환자의 연령 전신상태 등을 술전에 잘 평가하고 수술도중의 소견과 술자의 경험이나 기호에 따라 적절한 치료법을 선택하여 치료해야 한다. 후두 외상에 의한 기도 문제는 다른 외상에 비해 흔하지 않은데 이는 연골의 유연성과 후두의 가동성 그리고 후두가 하악과 흉골사이에 위치하여 외상시 보호받게 되는 해부학적 특성에 기인한다. 여러 요인으로 인하여 진단이 늦어질 수도 있는데 이러한 경우 심각한 증상이 초래 되거나 치료가 의 시기가 지나 후두 또는 기관 협착, 발성장애등의 후유증이 유발 될 수 있다.

Transoral $CO_2$ laser microsurgery has been widely used for various laryngeal diseases. Laser cordectomy for the management of early laryngeal carcinoma has advantages with regards to oncologic results, preservation of laryngeal functions, morbidity and cost in comparison to those of open surgery or radiation therapy. $CO_2$ laser is also applicable to benign vocal fold lesions such as nodules, polyps, cysts, reinke's edema, granulomas, papillomas, hemangiomas and glottis webs. $CO_2$ laser is suitable for microsurgery because it has small focus size and hemostatic effect. We should also recognize the risks of $CO_2$ laser for safe use.

An anterior glottic web can be congenital or develop as a result of trauma. The congenital webs indicate failure of normal separation of the two vocal cord primordia and the cicatrical membrane caused by accidental and operative trauma. When the web is small it rarely produces significant sympto-matology but larger webs may produce stridor as well as hoaresness in various degrees. Achievement of epithelialization of the anterior commisure after excision of a web, thus preventing adhesions from forming between the denuded vocal cords, is the principle underlying the surgical treatment of anterior glottic webs. Recently the authors experienced a case of anterior glottic web which occured in a 23 year old man after repeat removal of a papilloma several times in child-hood. The patient received treatment of a web excision followed by placement of a gold keel between the cords in the anterior glottis.

Background and Objectives : Vocal abuse and misuse and muscle tension dysphonia that have various movements of false vocal folds may be related to the development of benign vocal folds lesions, such as vocal nodules, polyps, and cysts. This study was designed to determine whether benign vocal folds lesions were related with movements of false vocal folds on phonation. Material and Methods : One Hundred and seventy eight subjects were studied. All subjects received otolaryngological evaluation including videostroboscopy, objective voice measures. Patients were diagnosed as normal shape of vocal folds (group a), approximation of bilateral false vocal folds (group b), approximation of unilateral false vocal folds (group c), lateralized extension of false vocal folds (group d), and medialized approximation of posterior false vocal folds (group e). We analyzed the results of benign vocal folds lesions in each group. Results : Differences were found between the normal shaped group and the abnormal shaped group. No differences were found between each abnormal groups except group d and e. Conclusion : The shape of false vocal folds was related to the benign vocal folds lesions.

It is well known that laryngeal papilloma is histopathological benign, but clinically one of the most troublesome disease in otolaryngologic department, usually seen in child age. Since Cleesmann reported papilloma of the vocal cord, 1817 first, the etiology had not been known exactly. The symptoms in children are dyspnea, dysphonia due to recurrence, and papilloma in adult can change into neoplasm. The papilloma is thought as real neoplastic lesion and there is not effective treatment, using now repeated removal and combined therapy. This report is based on the typical findings and progress of one case of laryngeal papilloma observed for the past 13 years with repeated removal and topical application of 5-FU at our department. Authors have experienced this subject is interesting that the change of the tumor region during the course than to any new therapeutic methods employed, and so report with some reviews of the literatures.
