Relapsing paraganglioma of the inferior laryngeal paraganglion: Case report and review of the literature

Abstract

Thyroid paragangliomas and inferior laryngeal or subglottic paragangliomas should be included under the term "paragangliomas" of the inferior laryngeal paraganglion. These tumors are slow growing, benign, hypervascular, and much more common in middle-aged women. Immunohistochemistry is essential for its diagnosis. Open, conservative surgery is the treatment of choice.

Laryngeal Paraganglioma: A Rare Clinical Entity Managed by Supraselective Embolization and Lateral Pharygotomy

“…This is not a good approach for vascular tumors, because hemorrhage might obscure visualization of tissue planes [6]. The biological behaviour of the tumor is not extensively defined as the tumor is rare and the malignant potential hardly exist [37]. All these lesions are treated by surgical resection which includes supraglottic or total laryngectomy and endoscopic resection [18,37].…”

All these lesions are treated by surgical resection which includes supraglottic or total laryngectomy and endoscopic resection [18,37]. Inferior laryngeal paragangliomas present in the subglottis having dyspnea and shortness of breath and need careful consideration for airway management pre-operatively [18,37].…”

“…Inferior laryngeal paragangliomas present in the subglottis having dyspnea and shortness of breath and need careful consideration for airway management pre-operatively [18,37]. Most of them were managed by total laryngectomy as the primary treatment [18,37]. Lateral pharygotomy approach is described for removal of supraglottic submucosal tumors, including paraganglioma [17].…”

“…This approach can be performed without a tracheostomy for smaller lesions, but for resection of vascular masses, a tracheotomy should be performed [6]. Also conservation laryngeal approaches are not attempted when cartilage involvement is seen radiographically [18,37]. Submucosal resection with meticulous dissection results in no postoperative dysphagia and excellent voice preservation [6].…”
