Late recovery from foreign body sinusitis after maxillary sinus floor augmentation

Area of Science:

• Otolaryngology
• Oral and Maxillofacial Surgery
• Infectious Diseases

Background:

• Maxillary sinus floor augmentation is a common procedure for dental implants.
• Complications can include graft infection and displacement, leading to sinusitis.
• Antibiotic resistance poses a challenge in treating sinonasal infections.

Observation:

• A 55-year-old male presented with recurrent sinusitis post-maxillary augmentation.
• Infection of a xenograft led to ethmoidomaxillary sinusitis and graft displacement.
• Initial surgical intervention and antibiotics failed to resolve the persistent sinusitis.

Findings:

• Computed tomography revealed retained graft fragments in the maxillary sinus.
• A subsequent endoscopic treatment facilitated spontaneous expulsion of the fragments.
• The patient experienced rapid recovery after fragment expulsion.

Implications:

• This case highlights the importance of thorough graft removal in managing post-augmentation sinusitis.
• Targeted endoscopic medication can be effective in resolving complex sinonasal infections.
• Successful revision sinus augmentation is possible after resolving graft-related complications.
