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.

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.

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.

The developmental and subsequent addition of laser technology to existing surgical techniques offered new and exciting Possibilities for improving traditional endoscopic operations and expanding the scope of the specialty of otolaryngology-head and neck surgery. Lasers were found to be Precise, but potentially dangerous, surgical instruments whose use was associated with certain distinct and unprecedented advantages, but also with many unique and potentially serious, and sometimes catastrophic complications. The Purpose of this study was to evaluate the of elation technique of $CO_2$laser, kinds of anesthesia, equipments of operating room, and education of medical staff. Four hundreds 4 cases of $CO_2$laser laryngeal microsurgery were reviewed for the safety of $CO_2$laser in laryngeal microsurgery. Vocal polyp (46,3%) was the most common pathology in our cases. The others were vocal nodule, Reinke`s edema, epiglottic cyst, laryngeal granuloma, laryngeal papilloma, intracordal cysts, laryngeal tuberculosis, laryngeal web, laryngotracheal stenosis, and laryngeal cancer. Following complete equipment controls, treatment area controls, maintenance, service and procedural controls, personel protective equipment, and warning signs, no complications were found in our cases. In conclusion, laryngeal microsurgery with $CO_2$laser could be done safely without complication if complete preoperative preparation and education of medical staff preceded.

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.

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.

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.

The microsurgery of the laryngeal lesions was introduced by Kleinsasser in 1965. This has been utilized for diagnosis, surgical management and education of the laryngeal lesions. The laryngomic-roscopic technique appear to be useful in the evaluation of the lesions which may be precancerous, since minor degrees of epithelial thickening and alterations in the pattern of fine vessels beneath the epithelium may be observed with greater clarity. With suspension laryngoscopy, the authors experienced 11 cases of the laryngeal lesions: polyp (4 cases), web formation between false cords and true cords (1), papilloma (4), laryngeal trauma (1), and squamous cell carcinoma (1).
