Laryngeal cysts: Clinical relevance of a modified working classification
University of Dundee, Dundee, Scotland, United KingdomThe Journal of Laryngology & Otology (Impact Factor: 0.67). 11/1988; 102(10):923-5. DOI: 10.1017/S0022215100106814
Laryngeal cysts from 72 patients were examined and reclassified according to a modified working classification. In this series, 47 patients (66 per cent) had epithelial cysts, 11 patients (15 per cent) oncocytic cysts and 14 patients (19 per cent) tonsillar cysts. Epithelial cysts were commonest in the region of the epiglottis (20/47) and laryngeal ventricle (24/47). Oncocytic cysts tended to lie in the region of the ventricle whereas tonsillar cysts occurred almost exclusively in the valleculae, epiglottis and pyriform region (13/14). The authors conclude that the modified working classification of laryngeal cysts is easy to apply, of clinical relevance, and allows classification of cysts where operative trauma to the specimen obscures the relationship of the cyst to the surface epithelium. The origin and significance of tonsillar cysts are discussed and a relationship to the lympho-epithelial cyst of the oral cavity is suggested.

ABSTRACT: To evaluate the sonographic appearance of laryngeal cysts, ultrasound examinations of 7 patients were evaluated retrospectively. The ultrasound studies were correlated with endoscopic findings. In two cases, the diagnosis was confirmed histologically, and in 4 patients, a CT examination was additionally performed. The endolaryngeal space could be well seen if the thyroid cartilage was not calcified (n = 6), whereas in one patient, the endolaryngeal part of the cyst could not be seen because of complete calcification of the thyroid cartilage. The laryngeal cysts presented as unechoic (n = 4) or hypoechoic (n = 3) masses, which demonstrated smooth margins in all cases and ranged in size from 6 to 38 mm. In three cases, the cyst was located in the endolaryngeal space, and in 4 cases, it extended cranial of the thyroid cartilage into the pre-epiglottic space. All cysts were closely related to the inner surface of the thyroid cartilage, from which they were delineated by a thin hyperechoic band in all cases.RöFo - Fortschritte auf dem Gebiet der R 08/1993; 159(1):38-42.

ABSTRACT: To our knowledge only a few defined studies have been carried out on laryngeal cysts. These cysts represent a mixed group of benign laryngeal lesions that can cause diagnostic and therapeutic difficulties. The aim of this study was to characterize their histological structure and localizations in the larynx as well as to discuss theories about their genesis. Between 1973 and 1996, 342 laryngeal cysts were treated at Phillips University of Marburg, while from 1990 to 1996, 74 were treated at Justus Liebig University of Giessen. In all, 416 laryngeal cysts were treated by endolaryngeal microsurgery. All clinical charts were reviewed retrospectively and surgical specimens examined histomorphologically. Findings showed that 58.2% of the laryngeal cysts were located in the glottic area and 18.3% in the ventricular folds. The remainder were located on the aryepiglottic fold (2.2%) and interarythenoid region (0.7%). Two congenital cysts were also treated. Approximately 56% of the laryngeal cysts were lined by squamous cell epithelium, 37% by respiratory epithelium and 7% by oncocytic epithelium. In general, the laryngeal cysts were found to be a collection of inhomogenous lesions from different histogenetic origins with diverse symptoms related to their site and size. On the basis of our investigations, a new classification was established concerning the genesis and development of laryngeal cysts by subdividing cysts into congenital cysts, retention cysts, and inclusion cysts.Archiv für Klinische und Experimentelle Ohren- Nasen- und Kehlkopfheilkunde 02/1997; 254(9-10):430-6.

ABSTRACT: Cysts of the true vocal cords are less common than other laryngeal cysts. They are usually easily recognized and managed. Patients present with complaints of hoarseness and/or dyspnea. We report our experience with 41 cases of cysts located in the true vocal cords. Clinical and histological aspects are reviewed and discussed. A new histological classification is proposed: A: cysts lined by columnar epithelium with mucous content; B: lined by columnar epithelium with cilia; C: lined b squamous epithelium without keratinization; D: lined by squamous epithelium with keratinization.Pathology - Research and Practice 02/2000; 196(2):95-8.
