Introduction: Trauma of the mid-face frequently results in injuries of soft tissue, teeth, and bony structures of the skull incorporating maxilla, zygomatic bone, naso-orbito-ethmoidal complex as well as supraorbital region and also occurs in combination with injuries of other parts of the body.

Objective:  The objective was to determine the severity of injury using Maxillofacial Injury Severity Score (MFISS) and Facial Injury Severity Score (FISS) score system and compare it with the presentation and prognosis of the fracture, apportioning the effective management.

Materials and Method: A hospital-based retrospective chart review was conducted at Second Affiliated Hospital of Jiamusi University. A total of 214 cases that were diagnosed as mid-face fractures and treated for that cause from January 2011 to December 2015 were included in the study.

Result: The average FISS score was 2.73±1.613 and MFISS was 20.24±12.257. MFISS/FISS showed significant relationship with age-group, gender, etiology, fracture pattern, time interval between trauma and surgery, time taken for surgery, time period in ICU and duration of hospitalization.

Conclusion: The sample of north-eastern Chinese population revealed somewhat similar demographic and epidemiological pattern of mid-face fractures to other locations within the country and region. The MFISS and FISS can be a reliable indicator of maxillofacial injury severity for management and prognosis of mid-face fractures.
