Abstract :

The objectives were 1) to study the factors affecting excessive bleeding in maxillofacial
region and 2) to give a suggestion to observe the excessive bleeding in maxillofacial region. Patients
with midfacial bone fractures from road traffic accidents were divided into 2 groups; 1) there were
64 patients with excessive bleeding and received nasal packing and 2) there were 902 patients with
no need for nasal packing. Data were statistically analyzed with chi-square test and binary logistic
regression to compare and determine impact of the factors affecting the excessive bleeding in
maxillofacial region. For the results, factors such as GCS score, skull base fracture, cranial vault
fracture, head injury and patterns of midfacial bone fracture were related to excessive bleeding
significantly (p < 0.001). For conclusion, those five factors were related to excessive bleeding signifi
cantly and had to be observed closely in severe maxillofacial injured patients and to treat promptly
and can decrease mortality rate.
