Here we describe the long-term outcomes of type I thyroplasty (TP-I) with silicone block implantation through histopathological assessments in a male patient who underwent pharyngolaryngectomy for secondary hypopharyngeal carcinoma 7 years after silicone implantation. A 66-year-old man presented with esophageal carcinoma and underwent subtotal esophagotomy. Subsequently, his left vocal fold exhibited fixation in a paramedian position, and he underwent TP-I with silicone block implantation 2 years after the primary esophageal surgery. His voice quality improved; however, he developed glottic carcinoma in the right vocal fold 6 months after TP-I and underwent laser cordectomy. Glottic carcinoma recurred 21 months later, and he underwent laser cordectomy again. Five years after the second laser surgery, he underwent pharyngolaryngectomy and neck dissection for hypopharyngeal carcinoma detected in the right pyriform sinus. We histopathologically examined a horizontal section of the resected larynx to assess silicone implant-related changes. Although migration of the silicone implant was not observed, a very mild foreign body reaction occurred around the implant. The patient is currently in remission. Our findings suggest that silicone implants are suitable for TP-I due to their remarkable affinity for human tissue and the low risk of a tissue reaction.
