성대낭종은 후두미세수술의 발달로 보다 정확한 진단 및 치료가 가능하므로서 관심도가 증가하고 있다. 성대 낭종은 낭종의 내용물 및 점막상태에 따라 저류성 낭종과 유표피성 낭종으로 분류하고 있는데, 저류성 낭종은 점액 분비선의 폐쇄로 점액이 저류되어 발생하며 유표피 낭종은 선천성으로 상피하층에 파묻힌 상피세포의 잔여물이거나 혹은 파묻힌 상피세포 위에 외상(음성남용)으로 손상된 점막이 재생하는 과정에서 발생한다는 설이 있다. (중략)

Mucocele is a clinical term of the localized superficial mucosal swelling caused by salivary retention after the obstruction or the rupture of minor salivary ducts. Various treatment methods have been suggested to lower its recurrence rate, including complete excision of lesion Biopsy punch can be used easily and simply for complete excision of mucocele. It has several advantages, such as convenience in use, low bleeding tendency, and nearly no requirements for post-operative management. In this case, biopsy punch was used for the removal of mucocele in an uncooperative child, which enable fast, simple and safe procedure, with a good result.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Mucoceles are categorized into two subgroups, extravasation type and retention cyst type. The etiology of extravasation type mucocele is related to mechanical trauma to the minor salivary gland excretory duct, resulting in extravasation of mucus into the fibrous connective tissue so that a cyst-like cavity is produced, but the epithelial lining is absent. Retention cyst type mucocele results from obstruction of minor salivary gland excretory duct, and cystic cavity is lined by epithelial cells. This case report presents a mucocele occurred on the lower lip, and caused by suture silk unremoved for 3 years. Suture silk penetrated and tore the minor salivary gland duct on the lower lip with subsequent extravasation of mucus into the fibrous connective tissue.

Mucoceles and Ranulas are mucous retention phenomena, ie, they develop from the extravasation or retention of mucous after trauma to the sublingual gland or one of the minor salivary glands. Mucoceles are chronic in nature, and local surgical excision is necessary. To minimize the chance for recurrence, the underlying feeder glands should be removed in continuity with the mucocele. Ranula is a term used for mucoceles that occur in the floor of the mouth Treatment consists of marsupialization and/or removal of the feeding sublingual gland. Marsupialization entails removal of the roof of the intraoral lesion. However this procedure is often unsuccessful. Some prefer initially to excise the entire sublingual gland. This case report presents two cases. one case was developed on lower lip and treated by marsupialization. There was no recurrence during follow up period.

Background and Objectives : Intracordal cysts may occur secondary to voice abuse and overuse or may be secondary to a remnant of epithelium trapped within the lamina propria. They nay occur spontaneously or may be associated with poor vocal hygiene. As the cyst enlarges it can start to significantly affect the vibratory region of the vocal fold. Recently, with the advancement of the microsurgical technique and the laryngeal stroboscopy, correct diagnosis of intracordal cyst have been increased. The aims of this study is to review the important clinical characteristics of the intracordal cyst. Materials and Method : In the present study, 121 cases of the intracordal cyst were treated by the microsurgical technique. These lesions were diagnosed before the operation with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with the findings observed during operations and the results of the biopsies. Results : The intracordal cysts were 121 cases in the 2595 patients who underwent laryngeal micorosurgery(4.7%). Ductal cyst were 88 cases and epidermoid cyst were 33 cases. The lesions are more frequent in women and anterior third of true vocal cord is more frequently involved site. With the indirect laryngoscopic examination, the ductal cysts are more frequently misdiagnosed as other diseases of the vocal cord such as vocal polyps or nodules. The degree of postoperative voice satisfaction is similar to that of vocal polyps. Conclusion : Intracordal cysts are very similar to the other mucosal disorders of the vocal cord and it may be misdiagnosed as vocal polyps or nodules, frequently. Therefore careful preoperative examinations for the vocal cord lesions with stroboscopy and other endoscopic instruments are important part of the correct diagnosis. An ideal treatment is enucleation of the cysts without upture of the cystic wall or injury of the lamina propria.

They may occur spontaneously or may be associated with poor vocal hygiene. As the cyst enlarges it can start to significantly affect the vibratory region of the vocal fold. With the advancement of the microsurgical technique and the laryngeal stroboscopy, correct diagnosis of intracordal cyst have been increased. The aims of this study is to review the important clinical characteristics of the intracordal cyst. Materials and Methods: In the present study, 212 cases of the intracordal cysts were treated by the microsurgical technique. These lesions were diagnosed before the operation with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with the findings observed during operations and the results of the biopsies. Results : The intracordal cysts were 212 cases in the 4,20 I patients who underwent laryngeal microsurgery (5.04%). Ductal cysts were 156 cases and epidermoid cysts were 56 cases. The lesions are more frequent in women and anterior third of true vocal cord is more frequently involved site. With the preoperative laryngoscopic examination, the intracordal cysts were mostly misdiagnosed as other disease of the vocal cord such as vocal polyps or nodules. And main cause of intracordal cysts was thought of vocal abuse. From view of the surgical approach, Ductal cysts was difficult to remove completely than epidermoid cyst without cystic wall rupture. Conclusion : Intracordal cysts are very similar to the other mucosal disorders of the vocal cord and it may be misdiagnosed as vocal polyps or nodules, frequently. Therefore careful preoperative examinations for the vocal cord lesions with stroboscopy and other endoscopic instruments are important part of the correct diagnosis. An ideal treatment is enucleation of the cysts without rupture of the cystic wall or injury of the lamina propria. And marsupialization is meaningful to ductal cyst that cannot be enucleated completely.

A 66-year-old woman described a 6-month history of hoarseness after upper respiratory infection. She was a house wife and referred from an outside clinic under a diagnosis of vocal fold nodules. Strobovideolaryngoscopy revealed bilateral vocal fold lesions, and decreased mucosal wave of both vocal folds. She was brought to the operating room for microsuspension laryngoscopy. Under general anesthesia, dual intracordal cysts on left vocal fold were completely resected with microflap technique. The lesion on the right vocal fold turned out to be a reactive fibrous mass, which was also resected. Dual intracordal cysts were confirmed histopathologically. The one was an epidermoid cyst lined with squamous epithelium, and the other was a mucus retention cyst lined with cuboidal epithelium. Postoperative voice was acceptable by the patient and the mucosal vibration has much improved after the surgery.

Background and Objectives : The intracordal cysts are more increasingly diagnosed and treated due to advanced laryngeal stroboscopy and laryngeal microsurgical technique. The intracordal cysts are frequently misdiagnosed as vocal polyp or nodule The purpose of this study is to evaluate clinical features of intracordal cysts. Materials and Methods : In the present series, 83 cases of the intracordal cysts treated with laryngeal microsurgery are reported. The intracordal cysts are diagnosed preoperatively with indirect laryngoscopy, laryngeal endoscopy, laryngeal stroboscopy and confirmed with laryngeal microsurgical findings and biopsies. Results : Intracordal cysts are 83 of 1900 patients treated with laryngeal microsurgery(4.4%)-ductal cysts are 56 cases and epidermoid cysts are 27 cases. Intracordal cysts are more frequent in women, forties and the frequent site is an anterior third of the true vocal cord. With the indirect laryngoscopic examination, the ductal cysts are frequently misdiagnosed as vocal polyps or nodules but the epidermoid cysts are relatively easily diagnosed. The etiologic factors of the intracordal cysts are suspected as voice abuse and upper respiratory infection. The degree of postoperative voice satisfaction is similar to that of the vocal polyps. Conclusion : Intracordal cysts are frequently misdiagnosed as polyps or nodules, therefore preoperative stroboscopic findings and laryngeal microsurgical findings is important. An ideal treatment is to enucleate the cysts avoiding rupture of cyst and injury of lamina propria of the vocal cord.

Ranula is a mucosal cyst that occurs in the mouth floor. This is a pseudo cyst caused by mucous retention within the tissue due to the rupture of catheter in the salivary gland. Ranula occurs mainly in a unilateral form and is characterized by painless bluish transparent swelling, with a increasing mass size. If the size is large, it can cause discomfort during swallowing, pronounciation, and mastication, but external swelling and infection is rare. Treatments include observation for spontaneous resolution, simple incision and drainage, marsupialization and excision. Marsupialization done by removing parts of the cyst wall and connecting it to the oral mucosa. It is a conservative procedure and recommended for children. It has advantages such as maintaining outline of oral tissue and less risk of damaging anatomic structure. Recurrence is common, mostly occurring within 4 months after surgery. This case is about a eight-year-old girl with ranula on the right mouth floor. This patient was treated with marsupialization that is one of treatment for ranula, and recurrence was not observed.

Ranula is a mucocele which occurs at the mouth floor and is mostly related to sublingual gland. In other words ranula is definded as a pseudocyst which occurs as the secretion duct of sublingual gland is destructed there as the saliva from the secretion duct flows out and retention in the soft tissue. The cause of ranula is destruction or obstruction of the duct. The clinical findings of ranula is a painless, unilateral bluish transparent swelling around the frenum and shows fluctuation when palpated. Histological finding represent a formation of cavity inside the connective tissue, but a pseudo-cyst can be seen which the wall of the cyst is composed of granulation tissue rather than epithelial cells. The first treatment of ranula can be considered as marsupialization. which induces the inner wall of the Ranula to be a part of oral mucosa. This case report shows a treatment of marsupialization with gauze packing in a young patient representing a clinical finding of characteristic ranula.
