Repairing Maxillary Sinus Membrane Perforations, Iatrogenic or Intentional: Two Case Reports

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Periodontology

Background:

• Maxillary sinus augmentation is crucial for dental implant placement in deficient posterior maxilla.
• Common complications include Schneiderian membrane perforation, bleeding, and implant loss into the sinus cavity.

Observation:

• Two unique cases of maxillary sinus augmentation complications are presented.
• Case 1: Large membrane perforation managed by graft removal and repair with a resorbable membrane.
• Case 2: Implant migration into the sinus successfully treated by retrieval, repair, and re-implantation with grafting.

Findings:

• Prompt and thoughtful management of sinus membrane perforations leads to predictable procedures with favorable outcomes.
• Addressing complications during the initial surgery prevents the need for more complex secondary procedures.

Implications:

• Effective techniques for managing iatrogenic or intentional sinus membrane perforations are vital.
• Successful treatment of complications enhances the predictability and success rates of dental implant procedures in the posterior maxilla.
