Laryngeal paraganglioma: an endoscopic diode-laser-assisted surgical approach: a case report.

Laryngeal paraganglioma is a rare vascular neuroendocrine benign tumour. Surgery is the standard treatment. The pre-operative gold standard is Magnetic Resonance Imaging with Gadolinum contrast. Computed tomography scans and angiography are also useful in making the diagnosis of paraganglioma before surgical intervention. A case of a large supraglottic paraganglioma is described. Complete excision of the tumour was achieved using microlaryngoscopical-laser surgical resection. No severe complications were observed. The patient was discharged from hospital without any complaints on the fourth post-operative day and she was disease-free 36 months after surgery. The effectiveness of this conservative endoscopic surgical procedure compared to the external approaches is discussed and it can be concluded that the endoscopic diode-laser resection of even extended laryngeal paraganglioma provides a good operative field and is a safe and effective technique.
