Type III fracture (31.35%) on Knights classification is commonest pattern followed by type VI (18.65%), type V (13.99%) and type II (14.77%). On Zing classification type B (53.89%) of Zing classifications is more prevalent followed by type C (19.69%) and type A2 (17.36%).Conclusions The study describes the demographic distribution, aetiology and pattern of Zygomatic complex fracture in a tertiary hospital.
