When the laryngeal web is small it rarely produces significant symptomatology. Large webs may produce stridor on both inspration and expiration, as well as hoarseness in various degrees. We have recently experienced with three cases of post-operative anterior glottic web after removal of the papilloma suffering from dyspnea and hoarseness. Layngeal webs with a definite voice problem or stridor should be managed surgically. And so, thyrotomy and a stainless steel keel insertion at the glottic level for repair of laryngeal web was performed. This technique has produced satisfactory result in all cases.

Anterior glottic webs shorten the free margins of the vocal cords and prevent air flow at their locations, thereby changing the potential vibratory characteristics of the vocal system. They are now more often iatrogenic from endolaryngeal surgical procedures, complications of intubation, chronic inflammation or due to penetrating and blunt trauma to the larynx. A wide range of treatment procedures are now available but the solution to acquiring a "normal" voice has remained elusive due to reflectory stenosis and scar formation. We present our recent experiences with glottic web in nine cases using KTP-532 laser vaporization and endolaryngeal silastic keel insertion technique. Postoperative speech assessment in our cases showed significant improvement in voice quality of 7 of 9 cases studied(77.8%), and no specific problems were not seen.

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.

Thyrotomy is very useful surgical procedure for laryngeal lesions; however, the web-formation at the anterior part of vocal cords is a frequent troublesome sequel of this procedure. Since the anterior commissure is not injured in Hayashi's hemithyrotomy, a web never results from this procedure. But the intralaryngeal exposure is too small to perform the surgery in this method. Partial thyrotomy was deviced as a new surgical technique to the glottic subglottic lesion. In partial thyrotomy, surgical procedure can be easily carried out under local anesthesia, in a wide field. This procedure has no side effects such as the web-formation at the anterior commissure, nor dyspnea after the surgery.

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)

후두격막은 1822년 Fleichman이 호흡곤란과 발성장애를 야기한 례를 최초로 보고하였으며 선천성으로나 후천성으로 발생할 수 있다. 선천성후두격막은 태생 10주경의 후두발생장애로 발생한다고 알려져 있으며 성문부위에서 가장 많이 발견되며 후천성후두격막은 감염, 외상, 수술 및 방사선조사 후 발생한다. 저자들은 최근 1례의 선천성후두격막과 4례의 후천성후두격막환자를 치험하였기에 문헌고찰과 함께 보고하는 바이다.

A laryngeal web is connective tissue covered with epithelium stretching between both sides of the true vocal cords. Laryngeal webs were first reported by Fleischmann in 1882, and they cause upper airway obstruction and abnormalities of phonation. Congenital webs result from an arrest of reabsorption of the epithelium of the larynx at the tenth week of the fetus. The most common site of webbing is the anterior commissural glottic area, followed by other glottic areas and rarely subglottic or supraglottic areas. We have experienced two cases of congenital laryngeal webs. The webs were operated in two different methods. The first was excised under magnified vision through a laryngoscope, with a silastic keel secured between the raw surfaces of the separated mucosa. In the second case, the deepithelialized surfaces were exposed for a certain time length to mitomycin C to prevent postoperative webbing. We, hereby, report our experience of the diagnosis and management of two cases of a rare entity known as the congenital laryngeal web, and discuss the results with relevant studies.

Background and Objectives: Topical administration of mitomycin-C (MMC) has been reported to reduce or delay scar formation in airway surgery. However, it is not infrequent to experience recurrent stenosis or adhesion of operative wound even after a meticulous MMC application during the laryngeal surgery. Therefore we aimed to evaluate the effectiveness of repeated postoperative MMC applications and the technical feasibility of MMC applications to the laryngeal wound at an outpatient clinic. Methods: We reviewed medical records of 13 consecutive patients who received office-based MMC applications after laryngeal airway surgery at Samsung Medical Center, Seoul, Korea. The patients were grouped into 3 categories according to the site of surgical wound and the purpose of MMC application; group I : supraglottic stenosis (n=5), group II : cordectomy and arytenoidectomy site granulation prevention (n=3), Group III : laryngeal web prevention (n=5). Outcomes in each group and adverse effects of repeated MMC applications were evaluated. Results: Office-based MMC application was successfully performed one to four times with a week interval for each patient. No significant complications were observed except slightly decreased mucosal wave in one female patient who received 4 times of MMC application at the anterior commissure of vocal fold. Repeated MMC applications at the outpatient clinic resulted in wide or acceptable supraglottic airway in group I, clean wound healing without granulation formation in group II, and negligible or no web formation at the anterior commissure in group III. Conclusion : Office-based topical administration of MMC to the larynx was technically feasible. Postoperative repeated MMC applications were effective to reduce recurrent stenosis or adhesion of supraglottic structures, to prevent granuloma formation after laser arytenoidectomy and glottic web formation after anterior commissure resection.
