Non-visualization of larynx is one of the reasons for failure of vocal fold surgery. Many otorhinolaryngologists may have a trouble in choice of alternative treatment if they experience this situation. The laryngeal mask airway could be alternative approach for this situation. We report a glottal papillomatous patient who was treated by pulsed dye laser via laryngeal mask airway after failure of vocal fold surgery via endotracheal intubation. The patient was a 73-year-old man. Laryngoscopy revealed a severe diffuse papillomatous lesion on right true vocal cord, anterior commissure, and partial left true vocal cord. The patient was refered for difficult laryngeal exposure during laryngomicrosurgey under general endotracheal anesthesia.

Background and Objectives : Dysphonia may be secondary to many different type of benign vocal cord lesions such as vocal polyp, vocal nodule, Reinke's edema, and intracordal cyst. Diagnosis and treatment of intracordal cysts are more difficult than other benign vocal cord lesions. But postoperative voice analysis of intracordal cyst have rarely been reported in the literature. The purpose of this study is to analyze aerodynamic and acoustic results and videostroboscopic findings before and after laryngomicrosurgery. Materials and Methods : We reviewed the pre and post-operative voice analysis results and videostroboscopic findings of 15 surgically treated patients of intracordal cysts at Severance hospital from Jun. 1997 to Nov. 1999 retrospectively. They were diagnosed with videostroboscopic findings, surgical findings, and pathologic reports. Their pre and post-operative speech were analyzed with MDVP(Multi Dimension Voice Analysis Program) of CSL(Computerized Speech Lab) and Aerophone II. Their pre and post-operative mucosal wave of true vocal cord was analyzed with videostroboscopy. In order to compare this results with normal group, 10 of normal persons were evaluated with same methods. Results : After the operation, mucosal wave of true vocal cord was improved in all patients. Postoperative acoustic and aerodynamic results were improved in almost parameters, but they did not reach the normal value. Conclusions : Videostroboscopy was essential in diagnosing intracordal cysts. By comparing the acoustic and aerodynamic results and video-stroboscopic findings before and after the laryngomicrosurgery, postoperative vocal function was defined more accurately and objectively. Almost parameters may be useful in assessing the quantitative changes in vocal quality before and after the laryngomicrosurgery.

In thyroid and parathyroid surgery, damage to the recurrent laryngeal nerve(RLN) is the most common iatrogenic cause of vocal cord paralysis. Identification and preservation of the BLNs and meticulous technique can siginificantly decrease the incidence of this complication. We experienced one case of NRRLN in a patient with the parathyroid adenoma. During the dissection, there was no branch to be considered as RLN in tracheoesophageal groove. While searching for the RLN, We found a white structure coursing horizontally at the level of cricoid cartilage directly arising from the vagus nerve in the carotid sheath. That structure was nonrecurrent recurrent laryngeal nerve(NRRLN) and NRRLNs are exceedingly rare. Awareness of the possibility of NRRLN will prevent the surgeon from accidentally severing one if it is encountered during surgery.

본방사선 치료 후에 후두 절제술을 시행할 경우 인두피부누공, 감염, 출혈 등 상처부위 합병증의 가능성이 높다. 저자들은 최근에 항암치료와 방사선 치료 후에 재발한 성문상부암에 대해 후두 전적출술을 시행하였고, 수술 66일째 생명을 위협하는 인두의 동맥 출혈을 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Laser is a relatively recent addition to laryngeal surgery. Since their invention, laser use and applications have expanded rapidly. The use of lasers in surgery has offered a time- and cost-efficient alternative to cold surgical techniques and has been used in the treatment of numerous laryngeal pathologies, including stenoses, recurrent respiratory papillomatosis, leukoplakia, nodules, malignant laryngeal disease, and polypoid degeneration (Reinke's edema). Despite the notable benefits, laser surgery is not without disadvantages. Laser heat can increase scarring and cause damage to adjacent tissue. With laser laryngeal microsurgery, there is potential for airway fire, endolaryngeal bleeding, perichondritis, chondritis, granuloma, surgical emphysema, laryngeal stenosis and web formation, postoperative edema and swallowing problem. Surgeons should be known about these complications and could manage properly.

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.
