Introduction: Zygomaticomaxillary complex fractures are second most common facial injuries. These fracture are managed either by open reduction with rigid fixation or conservatively. Objective: To compare infra orbital nerve outcome in zygomaticomaxillary complex fractures treated surgically and conservatively. Methodology: The current randomized controlled trial study was carried out at Oral and Maxillofacial Surgery Department, Sandeman Provincial Hospital/Bolan Medical College Quetta from 23/04/2018 to 22/10/2018 after the synopsis approval. Total sample size calculated was 100. 50 patients in Group-A were treated by open reduction and internal fixation technique and 50 patients in Group-B were managed conservatively without any intervention. All the data was recorded in a specialized proforma for this study. Data analysis was done by SPSS. Results: The overall mean age (SD) of the patient’s was 36.2±7.1 years. Most of the patients (n=64, 64.0%) were 31-45 years old. The male patients in our study were 65 (65.0%) whereas female participants were 35 (35.0%). For detection of mechanical threshold, the patients proportion with sensations at 3cm filament length was significantly lower in patients who underwent surgical treatment (78.0% vs. 100.0%; p-value<0.001) as compared to the participants managed conservatively. It was also lower significantly at 5cm and 7cm for Group-A in comparison to Group-B (p-value≤0.05). For detection of heat threshold, the patients proportion with sensation at 32°C was no different between Group-A and Group-B (p-value=0.529). However, proportion of patients with sensations at 35oC (64.0% vs. 100.0%; p-value<0.001) and 37oc (90.0% vs. 100.0%; p-value=0.022) was lower significantly in surgically treated patients. Pain threshold detection was significantly lower in patients who underwent surgical treatment (1.26±0.44 vs. 1.58±0.49; p-value<0.001) in comparison to conservative treatment. Conclusion: In patients with zygomaticomaxillary complex fractures, infra orbital nerve outcome was superior in patients managed conservatively than those treated with open reduction and internal fixation which advocates evading unnecessary intervention in such cases in future practice.

“…This study also supports other study conducted in gender based population showing male being more affected. 7,20 This may be because of male involved in physical activities, traveling and also practice drink and drive.

“…Previous studies show left side is predominantly affected in facial trauma which also favours our study. 19,20 This predominance of the side might be because most people are right hand and try to protect themselves from injury using their dominant hand. Also in the physical assault there will be more blows in the same direction of the opponent strong arm.…”

Background Zygomatic complex fracture is one of the commonest fractures of face leading to facial asymmetry. Various classification systems describing the pattern have been reported. The aim of this study was to determine the prevalence and pattern of Zygomatic maxillary complex fracture in tertiary centre hospital of Nepal based on two different classifications. MethodsA prospective observational study was conducted on College of Medical Sciences, Teaching Hospital, Chitwan from September 2021 to August 2023 with all cases of facial injuries. Computed Tomography scan of the cases were considered and 371 cases with Zygomatic maxillary complex fracture were studied. Apart from the demographic data, Knight and North classification and Zing Classification of the fractures were recorded. The data was tabulated and analysed using SPSS 20.ResultsZygomatic maxillary complex fracture was prevalent in third decayed of life with mean age of 28.45 years. Male (286) were more affected. Road traffic accident is primary cause of the fracture in our study. 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.

“…2 The zygomatic bone fractures are the one of the most common mid-facial bone fracture. 3 The commonest causes of ZMC fractures are RTAs, falls, violence, work and sports accidents, gunshot wound/blast injuries. Incidence of these fractures is more common among males than females with a 3-5:1 whereas in underdeveloped countries the ratio is as high as 10-40:12.…”

INTRODUCTIONhe facial skeletal serves a key importance in human body. 1 Apart from aesthetics, it gives sense of organ for smell, sight and taste. It also facilitates eating, chewing, breathing and speech .The facial bones share frontal bone, nasal bones, maxillae, zygoma and mandible. And the two maxillae form the middle third of facial skeleton and attached laterally with the two zygomatic bones at zygomaticomaxillary sutures. 2 Zygomaticomaxillary complex (ZMC) is the skeletal unit of middle third of face. The boundary of the cheek is defined by zygoma and it separates orbit from maxillary antrum and infratemporal fossa.The zygomatic bone is a quadrangular-shaped bone . It articulates with the four bones at four sutures i.e frontal, temporal, maxillary and sphenoid bones. These sutures are usual weakness areas for fractures. 2 The zygomatic bone fractures are the one of the most common mid-facial bone fracture. 3 The commonest causes of ZMC fractures are RTAs, falls, violence, work and sports accidents, gunshot wound/blast injuries. Incidence of these fractures is more common among males than females with a 3-5:1 whereas in underdeveloped countries the ratio is as high as 10-40:12. These are most frequent among people who are aged 20-30 years. 5 These fractures are diagnosed usually clinically, and
