'Y' Modification of the cutaneous incision of the preseptal transconjunctival approach for the management of zygomatico-maxillary complex fractures: A prospective clinical study.

Aim: The purpose of this clinical study was to evaluate the efficacy of the preseptal transconjunctival approach with Y modification of the cutaneous extension for the management of zygomaticomaxillary complex (ZMC) fractures.
Methods: This prospective interventional study was conducted at our institute from 2012 to 2020. The study included patients aged 15-65 years with displaced ZMC fractures. Patients with uncontrolled systemic conditions, infected and/or comminuted fractures were excluded. The variables evaluated were age, gender, mechanism of injury, fracture side, clinical features, surgical exposure time, adequacy of exposure, complications, scar evaluation scores and cosmetic outcomes. The parameters for comparison were operated versus non operated side Eye Fissure Index (EFI) and surgical exposure time was compared with respect to the types of scars.
Results: A total of 49 patients were included in this study. The average exposure time was 18.87 ± 1.92 min. The exposure of fracture site was excellent in 73.5 % and satisfactory in 26.5 %. The mean EFI of operated side was 34.2 ± 5.04 mm while that of non-operated side was 34.22 ± 5 mm. On comparison of the same there was no significant difference. Invisible scars were noted in 71.4 % and barely visible scars in 22.4 %. The comparison of exposure time with type of scars showed a significant association (p = 0.02). The complications noted were chemosis, lower eyelid edema, conjunctival granuloma and entropion. Cosmetic outcomes were fairly satisfactory.
Conclusion: The Y modification of the transconjunctival approach can provide excellent surgical exposure without the need for a second incision. Although this approach is technique sensitive and requires experience, the advantages outweigh the learning curve. Since this approach has been widely studied, a systematized review is recommended to further substantiate its reliability and advantages.
