Abstract:Objective To explore the standardized diagnosis and treatment for pharyngeal occult foreign body under laryngoscope.Methods Analyze and summarize the clinical data, diagnosis and treatment path and treatment effects of 74 cases of pharyngeal occult foreign body diagnosed and treated by the endoscopy center of foreign body from May 2021 to May 2022.Results 74 cases of occult pharyngeal foreign body were treated well. Among them, 36 cases were removed after careful laryngeal endoscopy. 32 cases of pharyngeal foreign body could be accurately located by thin-slice CT of the neck, of which 26 cases were then successfully removed with the assistance of laryngoscopy, 5 cases were successfully removed through small incisions with the assistance of general anesthesia laryngoscope, and 1 case was removed through cervical incision under general anesthesia. Another 6 cases of neck thin-slice CT failed to find obvious high-density foreign body shadows. After CT examination, repeated laryngoscopy was performed according to the patient's pain location. Finally, foreign body was successfully removed after local anesthesia through the pharynx.Conclusion CT examination of the neck is helpful for the detection and localization of occult foreign bodies in the pharynx, but small and low-density foreign bodies are easily missed. Therefore, according to the patient's pain location and degree of pain, repeated microscopic examinations with a focus on examining the occult area of the pharynx is the routine diagnosis and treatment path for pharyngeal occult foreign body.
