case_images: Figures 1C, D ). Fiber optic laryngoscopy showed an extrinsic 1-cm mass pushing against the posterior wall of the left pyriform sinus ( Figure 2A ). Utilizing the da Vinci SI robotic system outfitted with a 5-mm Maryland Dissector and a 5-mm flat-tipped monopolar cautery instrument, a hypopharyngeal incision measuring 1 cm was created utilizing electrocautery, followed by the careful dissection of the mass from the adjacent tissues employing a combination of blunt dissection and electrocautery techniques ( Figure 2B ).
