title: Laser surgical treatment of laryngeal paraganglioma.
abstract: Paragangliomas are rare benign neoplasms arising from the neural crest-derived paraganglia of the autonomic nervous system. In the larynx three different localizations of paraganglia are known. Most laryngeal paragangliomas arise from the supraglottic paraganglia. A review of the literature shows that the treatment of choice for laryngeal paragangliomas is surgical excision. Since the implementation of CO(2) laser surgery into laryngology in 1972, no reports of endoscopic laser surgical excisions of laryngeal paragangliomas have been published so far. We present the case of a 66-year-old female patient who suffered from a large (4 x 4 x 3 cm) left supraglottic paraganglioma. The tumour was completely excised utilizing the CO(2) laser. Histopathology and immunohistochemistry of the tissue presented the typical findings of a laryngeal paraganglioma. The pre- and post-operative management as well as the treatment strategies are discussed. To our knowledge the present case demonstrates for the first time a complete transoral CO(2) laser surgical resection of an advanced laryngeal paraganglioma.
