Subglottic Plasmacytoma: The Use of Jet Ventilation and Contact Nd:YAG Laser for Tissue Diagnosis

Abstract

Extramedullary plasmacytomas (EMP) constitute only 1% of all head and neck malignancies, with the vast majority occurring in the upper respiratory tract. The diagnosis of laryngeal EMP can be difficult since the symptoms are non-specific and the tumor usually mucosally covered. This paper discusses the successful combination of jet Venturi ventilation technique with suspension microlaryngoscopy and contact Nd:YAG laser for tissue diagnosis in a patient presenting with a large subglottic mass. Previous attempts using standard endotracheal intubation and forceps technique for biopsy failed to reach the diagnosis and resulted in significant bleeding from the biopsy site. A review of the disease and technique is presented.
