Operative technique in laryngeal paraganglioma: A case series and literature review

Abstract

Background: Laryngeal paragangliomas (LP) comprise a rare subset of head and neck neoplasms and are an important differential in the patient with a submucosal laryngeal mass. Methods: We discuss an operative technique using coblation assisted excision via laryngofissure in the cases of four confirmed LPs and discuss the current literature with respect to diagnosis and management of these patients. Results: Our case series of four patients demonstrate the laryngofissure approach for LP is safe, provides oncological cure and preserves laryngeal function. This technique with coblation has not been previously discussed in the surgical management of LPs. Patient-reported postoperative voice and swallowing outcomes were excellent in all patients. Whole body imaging techniques were utilized in all patients, with octreotide scintigraphy demonstrating synchronous lesions in two of the four patients—one had a retroperitoneal lesion, whilst another patient had multiple lesions in the skull base, paravertebral region, liver, and adrenal gland. Conclusions: Our cases also highlight the changing clinical paradigms in the diagnostic approach of LPs and an emerging role for octreotide scintigraphy in the workup of these patients. Coblation assisted excision via laryngofissure is efficient and effective in the surgical resection of LP. In patients with multicentric forms of LP, the size, side, and anatomic location of synchronous lesions should be considered in surgical planning to determine feasibility and safety of operative management. Level of Evidence: IV.
