Abstract

Purpose: This article outlines the management of a rare and severe nasoorbital injury resulting from a chainsaw kickback accident in a 60-year-old male. A meta-narrative review of English, French, and German literature indexed in PubMed, Embase, and the Cochrane Library up to January 8, 2024, accompanies the case report. Methods: This was a case report combined with a comprehensive review based on the 2011 Oxford Centre for Evidence-Based Medicine's highest and most recent level of evidence (LoE) and highest recommendation grade (RG). Rigorous selection criteria were applied. Results: The patient had an open nasal fracture, complex lacerations, and avulsion of the left eyelid, lateral orbital wall and lateral rectus muscle. Staged surgical interventions comprised repositioning and fixation of the fractured nose, buccal mucosal grafting for nasal mucosa and conjunctiva repair, titanium mesh and polydioxanone sheet for lateral orbital wall reconstruction, and subsequent muscle and eyelid repair. The second intervention 3 months postsurgery addressed lateral ectropion, nasal dorsal hump, and nasolacrimal system issues. Despite the rarity of such injuries, evidence-based discussions were conducted. Conclusions: Complex nasoorbital trauma resulting from chainsaw kickback necessitates a meticulous, staged surgical approach. The inside-out technique proved effective in addressing various challenges. This article concludes with evidence-based recommendations, highlighting the importance of adapting established principles to unique nature of these injuries.
