We would like to report this rare case of supernumerary teeth in the zygomatic bone that we hardly are able to find. The right supernumerary canine tooth has shown to be impacted in the zygomatic bone and protruded into the maxillary antrum associated with maxillary sinusitis. The left supernumerary canine tooth was embeded in the lateral wall of maxillary body. A 21-year-old female has complained of headache, purulent rhinorrhea and nasal obstruction with no evidence of tooth trouble. We held Caldwell Luc's operation and extracted the supernumerary canine tooth in the right maxillary antrum. We extablished the diagnosis as ""supernumerary teeth in the maxillary corpus"", based upon otolaryngologic and dental examination.
