Dog-bite injury of the oral and maxillofacial region is not common. We encountered a 45-year-old woman whose lips were injured by her pet dog on June 17, 1993. Her lower lip was partially bitten off, and we reconstructed it immediately. The postoperative course was uneventful.
A review of Japanese reports on dog-bite injuries of the oral and maxillofacial region over the past 20 years revealed that: 1) 14 cases were reported (male: female=5:9); 2), There were two peaks in the age distribution, one was the first decade and the other was the sixth decade; 3) The mean age was 33.5 years old; and 4) Differences were not seen between seasons, except that fewer cases occurred in winter.
