Summary

Maxillary sinus mucosa perforation during sinus lift surgery is common (56.16%) but does not lead to postoperative sinusitis or graft infection. Objective conditions and medical history showed no relation to perforation occurrence.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Periodontology
  • Dental Implantology

Background:

  • Maxillary sinus elevation is a common procedure in dental implantology.
  • Sinus membrane perforation is a known complication during this surgery.
  • Understanding perforation prevalence and outcomes is crucial for patient management.

Purpose of the Study:

  • To determine the prevalence of maxillary sinus mucosa perforation during sinus lift surgery.
  • To investigate the relationship between perforation and objective factors (septa, radiographic findings) and medical history (smoking, allergy).
  • To assess the influence of perforation on postoperative sinusitis and bone graft outcomes.

Main Methods:

  • Evaluation of 146 sinus lift procedures in 118 patients.

Related Experiment Videos

  • Classification of perforations based on size and treatment.
  • Statistical analysis to identify correlations between perforation and various factors.

    • Main Results:

    • The prevalence of sinus mucosa perforation was 56.16%.
    • No significant relationship was found between perforation and sinus septa, smoking, radiographic thickening, cystic lesions, or prior sinus allergy.
    • Despite the high perforation rate, no cases of bone graft infection or maxillary sinusitis were observed postoperatively.

    Conclusions:

    • Maxillary sinus mucosa perforation is a frequent occurrence during sinus lift procedures.
    • Perforation does not appear to increase the risk of postoperative sinusitis or graft complications.
    • Clinical monitoring is essential, but routine prophylactic measures for sinusitis may not be necessary solely due to perforation.
