A novel surgical approach for hypopharyngeal carcinoma resection via the paraglottic space

Abstract

Abstract Background Conservative surgery has proven advantageous in controlling hypopharyngeal squamous cell carcinoma (HSCC) and preserving speech and swallowing function in carefully selected patients, typically with early T-stages diseases. A variety of modified surgical procedures or techniques have been proposed. Methods In this study, we present a novel surgical approach for hypopharyngeal carcinoma resection utilizing the paraglottic space. Results The paraglottic space approach can help expose neoplasms under direct vision and save mucosa during surgery while sufficiently preserving laryngeal function, thus benefiting postoperative swallowing and reducing complications. A large cohort of 426 patients with HSCC underwent surgical treatment at our institution using this approach, demonstrating an overall survival (OS) rate of 52.3% and low incidences of postoperative complications. Conclusions This surgical approach can be applied in patients with the lesions that do not involve the paraglottic space.
