Summary
Maxillary sinus floor elevation surgery using autogenous bone grafts appears safe for patients without pre-existing sinusitis. Post-operative evaluations showed no significant long-term clinical consequences on sinus physiology.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Sinus Anatomy and Physiology
Background:
- Maxillary sinus floor elevation is a common procedure for dental implant placement.
- Understanding the impact of this surgery on sinus physiology is crucial for patient outcomes.
Purpose of the Study:
- To prospectively assess the effects of maxillary sinus floor elevation surgery on maxillary sinus physiology.
- To evaluate changes in mucosal pathology, microbiology, and histology following the procedure.
Main Methods:
- Prospective study involving 17 patients undergoing sinus floor elevation with iliac crest bone grafts.
- Unilateral endoscopic examination, mucosal biopsy, and sinus lavage performed preoperatively and at 3 and 9 months postoperatively.
- Microbiological and morphological analyses of collected samples.
Main Results:
- A transient increase in bacterial cultures was observed at 3 months, returning to baseline by 9 months.
- No significant postoperative morphological changes like fibrosis or altered inflammation were noted.
- An increase in goblet cells was observed, but without apparent clinical consequences.
Conclusions:
- Maxillary sinus floor elevation with autogenous bone grafts does not appear to cause significant clinical issues in patients without prior sinusitis.
- The procedure demonstrates a favorable safety profile regarding maxillary sinus physiology in the evaluated timeframe.
