Abstract:Objective To investigate the clinical manifestations and surgical methods of laryngopharyngeal masses in the neonatal population.Methods By retrospectively analyzing three cases of the laryngopharyngeal masses in neonates treated in the Second Hospital of Lanzhou University from 2020 to 2022, their clinical manifestations and treatment methods were summarized and analyzed. The three patients included one case of laryngeal cyst, one case of pharyngeal hairy polyp and one case of pharyngeal teratoma.Results All three cases presented with difficulty in breathing or sucking. And all of them underwent the surgical treatment of laryngopharyngeal masses under nasal endoscopy-assisted support laryngoscope. Follow-up for more than 10 months, all of them showed no recurrence.Conclusions The application of nasal endoscopy can help to clarify the relationship between the base of the masses and its surrounding tissues, determine the scope of surgical resection. The surgical treatment of laryngopharyngeal masses under nasal endoscopy-assisted support laryngoscope can completely remove the masses, adequately stop the bleeding, and avoid complications. It has certain advantages when applied to neonate patients.
