발성장애와 호흡곤란을 주소로 하는 성대 전연부 격막은 후두병변의 부적절한 치료, 만성염증 또는 외상 등의 후천적인 원인으로 발생하는 경우가 많다. 성문중 가장 협소한 부위인 전연부에 발생한 격막에 대하여는 여러 가지 다양한 치료방법이 보고되고 있지만, 재협착의 가능성이 높고, 치료후 반흔 조직에 의하여 음성의 질을 높이는데 한계점이 있다. (중략)

Laryngomicrosurgery is common procedure applying to benign laryngeal lesion. Suspension of the laryngoscope is a vital component of Laryngomicrosurgery. Suspension laryngoscopy allows for bimanual surgery and a stable operating platform. Little information is known about oropharyngeal & vocal fold complications of suspension laryngoscopy. Because laryngomicrosurgery is dependent upon suspension laryngoscopy, surgeons should fully understand the risks of suspension laryngoscopy to properly educate and care for patients undergoing suspension laryngoscopy. That is problem to allow otolaryngologist is embarrassing, for voice restoration surgery are not satisfied with the results. The authors reviewed mechanical and phonological complications after laryngomicrosurgery.

Vocal fold scarring is an intractable phonosurgical condition. The number of patients with vocal fold scars is increasing with the aging of society and with the increasing application of laryngeal microsurgery. Many methods are available to treat these, including voice therapy, stem cells, regenerative scaffolds, and growth factors. However, no standard treatment strategy has yet been established, and novel techniques are required. Basic fibroblast growth factor has been shown to be effective for the treatment of mild chronic vocal fold scarring. The combined use of basic fibroblast growth factor and regenerative scaffolds is currently under investigation. Here, we report a female patient in whom vocal fold scarring developed after two laryngeal microsurgeries. We performed laryngeal microsurgery to remove the scar tissue and used basic fibroblast growth factor and a collagen scaffold to promote healing. The patient's voice quality was greatly increased, and she was content with her voice after 2 years of follow-up. This is the first report of this methodology in Korea and is presented along with a review of the literature.

Background and Objectives : The clinical reports for the treatment of vocal fold scar and sulcus vocalis are limited, also there is no best one for the treatment of them. This study is to evaluate the effect of Injection laryngoplasty (IL) for the treatment of vocal fold scar and sulcus vocalis. Materials and Methods : from January 2013 to May 2015, the Nineteen patients who were diagnosed as vocal fold scar, sulcus and atrophy, and underwent IL, were engaged in this study. Clinical information and voice parameters were analyzed by retrospective chart review. Pre and post voice parameters were compared. Results : Subgroups of diagnosis were classified into sulcus vocalis for 12 patients, vocal fold scar for 5, and atrophy for 2. IL was performed under local anesthesia through cricothyroid membrane except one patient. Atesense$^{(R)}$, Radiessess$^{(R)}$, and Rofilan$^{(R)}$ were used as injected materials in 9, 9, and 1 patients respectively. Maximal phonation time (p=0.0124), dynamic range (p=0.0028), pitch range (p=0.0141), voice handicap index (p=0.028), glottal closure (p=0.0229), and mucosal wave (p=0.0132) had significant improvement for post-IL voice assessment than Pre-IL. While GRBAS, Mean flow rate, Jitter, Shimmer, Harmony to Noise ratio didn't have improvement. Conclusion : IL is a feasible option for the treatment of glottis incompetence with normally mobile vocal folds such as sulcus vocalis and vocal fold scar.

Laryngeal web was first reported by Fleischmann in 1822, and it causes upper airway obstruction and abnormalities of phonation. Congenital webs result from an arrest of development of the larynx around the tenth week of fetal life. Acquired webs may result from cicatrical strictures of infectious lesion, traumatic and postoperative wounds. The most common site of webbing is glottic, followed by subglottic and supraglottic. We have experienced a case of simultaneous glottic and supraglottic laryngeal webs probably due to tuberculous lesions in 28 aged male who was treated by endolaryngeal microsurgery.

Laryngeal web is formed from various causes, and it is a scar tissue covered with epithelium on both sides. The purpose of the laryngeal web surgery is to cover the vocal cords with healthy epithelium and to achieve the normal or near normal function of respiration and phonation. Until now, a lot of surgical procedures were introduced, but have some merits and disadvantages. Recently authors tried this new surgical technique on 6 patients using the suspension laryngomicroscope under the intubation general anesthesia, which was to suture the upper and lower edges of the severed web. This new approach has several advantages; 1) familiar instruments and visual field 2) no unnecessary surgical trauma beyond the operation field 3) one stage operation 4) shorter operation time 5) no serious complications 6) short hospitalization, etc.
