“…Bony compression, haematoma, or neurogenic inflammation in the IOC can lead to Wallerian degeneration which, in turn, can result in ION hypoaesthesia. 15,18 In the current study, fracture line involvement of the IOC was inherently associated with type B and C fractures, and was significantly associated with ION hypoaesthesia. In the literature, up to 95% of type B and type C fractures involve the IOC.…”

Study Design: Retrospective study. Objective: Zygomaticomaxillary complex (ZMC) fractures are common facial injuries with heterogeneity regarding aetiologies, fracture types, infraorbital nerve (ION) involvement, and treatment methods. The aim of this study was to identify associations between aetiologies, fracture types, and neurological complications. Additionally, treatment methods and recovery time were investigated. Methods: Medical files of 272 patients with unilateral and bilateral ZMC fractures were reviewed, whose cases were managed from January 2014 to January 2019 at the Department of Oral and Maxillofacial Surgery, University hospitals Leuven, Belgium. History of ION sensory dysfunction and facial nerve motoric dysfunction were noted during follow-up. Results: ION hypoaesthesia incidence was 37.3%, with the main causes being fall accidents, road traffic accidents, and interpersonal violence. Significant predictors of ION hypoaesthesia were Zingg type B fractures ( P = 0.003), fracture line course through the infraorbital canal ( P < .001), orbital floor fracture ( P < 0.001), and ZMC dislocation or mobility ( P = 0.001). Conclusion: Of all ZMC fractures, 37.3% exhibited ION hypoaesthesia. Only ZMC Zingg type B fractures (74.0%) were significantly more associated with ION hypoaesthesia. ION hypoesthesia was more likely (OR = 2.707) when the fracture line course ran through the infraorbital canal, and was less dependent on the degree of displacement. Neuropathic pain symptoms developed after ZMC fractures in 2.2% patients, posing a treatment challenge. Neuropathic pain symptoms were slightly more common among women, and were associated only with type B or C fractures. No other parameters were found to predict the outcome of this post-traumatic neuropathic pain condition.

“…In spite of disruption of the ZMC bones by its fractures, infraorbital foramen lies just lateral to a line between the anterior nasal spine and Whitnall's tubercle (clinically nasal tiplateral canthal ligament line) and lateral to the root of maxillary canine. These fixed reliable landmarks help to avoid mental nerve injury during OR/IF of ZMC fractures [9].…”

Infraorbital foramen localization in orbitozygomatic fractures: a CT study with intraoperative finding

Abstract: Even though ZMC fractures disturb the anatomical location of the ZMC bones, there are still preserved reliable fixed landmarks maxillofacial surgeons can depend on to identify and preserve ION.
