Late-onset inflammation (L.O.I.) after alloplastic implant use is a distinct condition separate from acute infections, emerging months or years after surgery. In Asian rhinoplasty, L.O.I. often presents as fluctuating swelling due to trauma, foreign body reactions, or low-grade infections and may progress to capsular contracture. Advanced cases can develop cystic lesions with mucoid content, sometimes leading to skin puncture and pus drainage, requiring surgical intervention. Accurate pathological classification demands full specimen analysis to identify features like synovial metaplasia and avascular scar tissue. Managing L.O.I. involves careful surgical planning, with total capsulectomy and the use of autogenous grafts essential for restoring tissue integrity and achieving favorable outcomes.

摘要

Late-onset inflammation (L.O.I.) after alloplastic implant use is a distinct condition separate from acute infections, emerging months or years after surgery. In Asian rhinoplasty, L.O.I. often presents as fluctuating swelling due to trauma, foreign body reactions, or low-grade infections and may progress to capsular contracture. Advanced cases can develop cystic lesions with mucoid content, sometimes leading to skin puncture and pus drainage, requiring surgical intervention. Accurate pathological classification demands full specimen analysis to identify features like synovial metaplasia and avascular scar tissue. Managing L.O.I. involves careful surgical planning, with total capsulectomy and the use of autogenous grafts essential for restoring tissue integrity and achieving favorable outcomes.
