we describe a rare case of laryngeal fasciitis ossificans. a 58-year-old man presented with hoarseness and a nodule was found in the larynx. excisional biopsy was performed, and follow-up laryngoscopy showed complete resolution of this reactive lesion, and normal laryngeal function. the 0.6 cm diameter nodule was well circumscribed and histologically, the lesion was composed of uniform woven bo...

Pacienti s operabilním karcinomem hrtanu mohou být léčeni larynx-záchovnými postupy nebo totální laryngektomií. Larynx záchovné jsou standardem v časných stadiích a zahrnují larynx-šetřící chirurgický výkon (endoskopický zevní parciální laryngektomii), který je preferován, radioterapii. U lokoregionálně pokročilých stadií obvykle zvažován nechirurgický postup,...

Larynx is part of the upper respiratory tract composed of cartilaginous skeleton, muscles and mucus lining inside. This structure keeps larynx open for air passage and is one of the important factors in producing voice. A good knowledge of larynx dimensions is neccessary to obtain better results in the treatment of laryngeal disorders. The size of larynx and its dimensions are subject to sex, r...

The vertical position of the larynx seems to be relevant to voice function. As a high vertical larynx position is often seen in hyperfunctional and strained voices, a lowering of a habitually elevated larynx is sometimes a specific goal in clinical voice therapy and different larynx-lowering exercises are used to achieve this goal. Earlier investigations have shown that pitch and to some extent...

background: actinomycosis is an indolent, slowly progressive infection caused by non acid fast, gram positive, anaerobic or microaerophilic bacteria. the most common site of actinomycosis infection is cervicofacial region. bacteriologic identification from infected site or detection of sulfur granules confirms the diagnosis. we report a rare case of simultaneous infection of larynx and lungs ac...

laryngeal leiomysarcoma is an extremely rare malignancy originating from smooth muscle cells. its rarity is due to the fact that only less than 50 cases of pure laryngeal leiomyosarcoma and less than 10 cases of hypopharyngeal leiomyosarcaoma have been reported in modern medical literature.  even though the clinical presentation mimics that of a laryngeal carcinoma forming the major bulk of the...

Introduction: Due to the effect of radiation on both the tumor and the surrounding normal tissues, the side effects of radiation in normal tissues are expected. One of the important complications in the head and neck radiotherapy is the doses reached to the larynx and spinal cord of patients with non-laryngeal head and neck tumors.   Materials and Methods: ...
