A laryngocele is relatively uncommon disease, and it has abnormal dilatation of the laryngeal saccule or appendix of laryngeal ventricle. Etiology and pathogenesis of laryngocele has still dabated, but laryngocele has high relationship with glass blower, wind instrument player, chronic cough, laryngeal cancer, etc. We have experienced an unusual case of laryngocele combined with laryngeal carcinoma. We discuss the relationship of laryngocele and laryngeal carcinoma, and the current literature is reviewed.

Cervicothoracic thymic cysts are rare and difficult to diagnose preoperatively. We report a case of a cervicothoracic thymic cyst presenting as a lateral neck mass and mimicking a laryngocele in a 3-year-old boy and its definitive management.

Tracheal diverticulum is very rare, that is usually an incidental finding at routine chest computed tomography scan. Differential diagnosis of tracheal diverticulum includes pharyngocele, laryngocele, Zenker diverticulum, apical lung hernia, blebs and bulla, and pneumomediastinum. Treatment options can be devided into medical and surgical. The majority of patients is asymptomatic and requires no specific intervention. We experienced one case of tracheal diverticulum in patient with tongue cancer and report it with reviews of literature.

Recently, conservative and bloodless operative procedures have been focused, so that endoscopic laser have been used. However application of endoscopic laser surgery for laryngeal lesion is capable for followings: (1)capability of delivery through an operating microscope, (2) vaporization of ultraspot. $CO_2$ laser which has been used, has limitations for voice improvement because of 700 micron beam spot. KTP-532 laser which is capable of delivery through an operating microscope vapore 200 micron ultraspot has developed and applied to microlaryngeal surgery. We have experienced 60 cases who were contracted with hoarseness(53 cases of benign lesions vocal nodule 13, vocal polyp 13, bilateral diffuse polyposis of vocal cords 11, intracordal cyst 8, vocal papilloma 5, laryngocele 1, laryngeal stenosis 2 and 7 cases of malignant lesions : laryngeal carcinoma stage I and II) since 1991. We operated them with KTP-532 Laserscope(3 Watt/0.05 sec., pulsed or continuous. San Jose, Calif, USA). Forty eigh cases(90.6%) of 53 bengin laryngeal lesions and 4 cases(57.1%) of malignant lesions were significantly improved in their voices. There were a few complications and technical problems, but laser surgery alone had a limitation to eradicate the disease.

The plunging ranula or cervical ranula is amucous extravasation cyst of the sublingual gland. It is slightly common in females, shows no side preference, and is more prevalent in the second and third decades of life. It typically manifests as a painless, nonmobile swelling in the neck. The pathogenesis of plunging ranula is the discontinuities of the mylohyoid muscle in a position that would allow extravasation of sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid of epithelium or endothelium, with a vascular fibro-connective tissue wall containing some chronic inflammatory cells and macrophages stuffed with mucin. The correct diagnosis is essential for the most effective treatment, which is exicision of the sublingual gland. The plunging ranula must be differentiated clinically and histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst, lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor. We report a case and review the literatures, in our case, 23-year old man were diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent surgery via a cervical approach. The ranula reached the anterior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although total sublingual gland excision was not performed, no recurrence was observed during 6 months follow-up periods.

Background and Objectives : Benign neoplasms of the larynx are rare, and papillomas account for approximately 90% of these neoplasms. Other benign neoplasms of the larynx are very rare and form a hetergenous group. We present clinical manifestations of unusual benign neoplasms based on our experiences and review of literatures. Materials and Method : We reviewed retrospectively the clinical records of 14 patients with benign neoplasms of the larynx, excluding papillomas, that were examined in our department during 11-year period from 1995 to 2006. Results : The presenting symptom was most commonly progressive dysphonia. Pathologic diagnosis revealed 5 cases of hemangioma, 3 granular cell tumor, 2 amyloidosis, 2 laryngocele, 1 schwannoma, 1 chondroma. Subsites of the neoplasms were 5 in true vocal cord, 3 in arytenoids, 2 in false vocal cord, 2 in supraglottis, and others were subglottis ; aryepiglottic fold. Treatment was surgical, by a external approach in 1 case of chondroma, and by laryngoscopic approach in other cases. In laryngoscopic approach, carbon dioxide laser was used in 10 cases. Postoperative course was satisfactory. Recurrence was encountered in I case of amyloidosis and revision operation was done 3 times. No recurrence was encountered in other cases. Conclusion : Uncommon benign neoplasms of the larynx require high index of suspicion and histological confirmation. Complete excision with an attempt to maintain normal structures generally results in cure.

False vocal fold hypertrophy caused by diverse pathologic lesion, such as laryngeal amyloidosis, laryngeal lipidosis, laryngocele, saccular cyst and sulcus vocalis. False vocal fold hypertrophy, however, is also caused laryngeal structure deformity, irrespective of pathologic lesions. In this article, we report some cases of false vocal fold hypertrophy caused by inward bowing of thyroid cartilage. At the clinic of the department of otorhinolaryngology in Gangnam Severance Hospital, with 3 male complained of hoarseness as subjects, and comfirmed of false vocal fold hypertrophy using the stroboscopy and larynx CT we checked vocal fold and laryngeal structure. Three patients with apparent hypertrophy of false vocal fold were investigated with computerized tomography (CT). In all patients, marked concavity of thyroid cartilage was revealed in CT scan at the level of the false vocal fold, and this deformity of the thyroid cartilage seemed to cause a protrusion of false vocal fold which taken as hypertrophy in stroboscopy. Careful palpation of the larynx and a CT scan taken at the level of the false vocal fold should be useful in determining whether hypertrophy of the false vocal fold is pathologic. For the next articles, It is necessary to discuss for the cause, diagnosis, treatment and prevention of inward bowing of thyroid cartilage.
