Case in brief
Three patients developed persistent subclinical graft-related infections following lateral sinus floor elevation (SFE) and implant placement. Initial pharmacologic treatment and debridement provided partial relief, but subtle sinonasal symptoms persisted. Six months later, imaging revealed sinus opacification and ostial blockage. Surgical intervention involved partial graft removal and drainage, leading to successful implant retention in two patients, while one implant was removed due to infection-related complications.
Diagnostic / clinical pearl
Clinicians should be aware that persistent subtle sinonasal symptoms may indicate unresolved subclinical infections following sinus floor elevation, necessitating thorough reassessment.
Why it matters
Recognizing and addressing lingering symptoms postoperatively can prevent complications and improve patient outcomes in sinus floor elevation procedures.
