In the human larynx, implants a primarily used for the correction of glottis insufficiency. In a broader sense laryngeal stents may be considered as implants as well. Laryngeal implants can be differentiated into injectable and solid. The most important representatives of both groups are discussed in detail along with the respective technique of application. Laryngeal stents are primarily used ...

This paper discusses a rare case of small cell neuroendocrine carcinoma of the larynx. The diagnosis was based on histological investigation expanded with immunohistochemical tests of a fragment of a tissue taken through laryngofissure. The treatment in case of small cell carcinoma diagnosis differs from the treatment in case of other neuroendocrine carcinomas and squamous cell carcinomas of th...

Leiomyosarcoma involving the larynx is extremely rare and may be difficult to diagnose. Likewise, because of the rarity of this lesion, little information exists with regard to long-term follow-up or optimal management. Reported here is a review of the literature and a case report of a patient with leiomyosarcoma of the larynx treated by surgery alone with 5 years of follow-up.

Laryngeal squamous cell carcinoma is very common in head and neck cancer, with high mortality rates and poor prognosis. In this study, we compared expression profiles of clinical samples from 13 larynx tumors and 10 non-neoplastic larynx tissues using a custom-built cDNA microarray containing 331 probes for 284 genes previously identified by informatics analysis of EST databases as markers of h...

The physiological aim of vocal exercises is mostly understood in intuitive terms only. This article presents an attempt to document the phonatory behavior induced by a vocal exercise. An elevated vertical position of the larynx is frequently associated with hyperfunctional phonatory habits, presumably because it induces an exaggerated vocal fold adduction. Using the multichannel electroglottogr...

BACKGROUND Non-invasive ventilation is sometimes unable to provide the respiratory needs of very premature infants in the delivery room. While airway obstruction is thought to be the main problem, the site of obstruction is unknown. We investigated whether closure of the larynx and epiglottis is a major site of airway obstruction. METHODS We used phase contrast X-ray imaging to visualise lary...

PURPOSE In the present study, the authors investigated the association between wet vocal quality (WVQ) and prandial material in the larynx during phonation. The presence of such material is indicative of oropharyngeal dysphagia and results from entry of material into the laryngeal vestibule during swallowing. The primary aim of the study was to determine whether clinicians reliably perceive WVQ...

Changes in vertical larynx position during singing were studied in professional singer subjects using the two-channel electroglottograph recently presented by Rothenberg (1992). The evaluation of the method and the examination of the laryngeal behaviors of professionnl singers were the main aims of the study. The significance of pitch, vocal loudness and lung volume to vertical larynx position ...
