Objective: The loss of a scalpel or a needle during surgery can threaten the health of the patient and lead to additional costs, and radiographical assistance during surgery has been the only recovery method. This study evaluates the efficacy of a metal detector compared with conventional radiology for recovering a needle lost in the oropharynx during surgery.
Method: Different fragment sizes of needles normally used in pharyngoplasty were embedded at different locations and depths in a lamb's head. Three experienced and three junior otolaryngologists searched for the needle fragments using a metal detector and conventional radiology.
Results: All fragments were found with each method, but the mean searching time was 90 per cent shorter with the metal detector.
Conclusion: A metal detector can be a useful tool for locating needles that break during ENT surgery, as it requires less time than conventional radiology and avoids exposing patients to radiation.
