Abstract

A 33-year-old male with left paranasal sinusitis was treated by antral puncture at another clinic. The puncture needle broke, and part of it remained in the left maxillary sinus. On the same day we removed the broken needle from the antrum by C aldwell-Luc antrotomy. We examined the broken needle by X-ray and electron microscopy and found that the break was due to metal corrosion.
