Effects of maxillary sinus floor elevation surgery on maxillary sinus physiology

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 3 2003
Nicolaas M. Timmenga
In a prospective study, the effects of elevation surgery of the maxillary sinus floor on maxillary sinus physiology were assessed. Seventeen consecutive patients without preoperative anamnestic, clinical and radiological signs of maxillary sinusitis underwent sinus floor elevation surgery with iliac crest bone grafts. All patients were subjected to unilateral endoscopic examination of the maxillary sinus, taking of a biopsy specimen from the sinus floor mucosa, and collection of a sinus lavage-fluid aspirate. This triad of evaluations was performed immediately preceding the elevation procedure, and 3 months (at implant insertion) and 9 months (at uncovering of implants) postoperatively. All procedures were performed under general anesthesia. Preoperatively, three out of 17 patients showed pre-existing mucosal pathology endoscopically, while the 3- and 9-month results revealed the presence of mucosal pathology in four and two patients, respectively. The 3-month microbiological evaluation showed a significant increase in cultures with bacterial growth, while the 9-month culture results were comparable to the preoperative status of the maxillary sinus. Morphologically, neither fibrosis nor an altered inflammatory response or thickening of the epithelium and lamina propria was observed postoperatively. The number of goblet cells in the epithelial layer was increased. From this study it is concluded that the effect of maxillary sinus floor elevation surgery with autogenous bone grafts does not appear to have clinical consequences in patients without signs of pre-existing maxillary sinusitis.

Symptoms and signs in culture-proven acute maxillary sinusitis in a general practice population

APMIS, Issue 10 2009
JENS GEORG HANSEN
The objective of this study was to assess symptoms and signs in patients with maxillary sinusitis and a bacteriological diagnosis obtained by sinus aspiration or lavage. Designed as a prospective cohort study in general practice, the study included 174 patients, aged 18,65 years, suspected of having acute maxillary sinusitis by their general practitioner. The main outcome measures were the independent association of symptoms, signs, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) concentration and confirmed infection with the predominant bacterial pathogens Streptococcus pneumoniae and Haemophilus influenzae. The predominant organisms found in patients with acute maxillary sinusitis were S. pneumoniae and H. influenzae. Body temperature >38 °C and maxillary toothache were significantly associated with the presence of S. pneumoniae and H. influenzae. Positive bacteriological culture results were significantly associated with increasing ESR and CRP values. None of the symptoms and signs, with the exception of body temperature >38 °C and maxillary toothache, were particularly sensitive indicators of the specific aetiology in patients with acute maxillary sinusitis. Elevated ESR and CRP values were significantly associated with positive bacteriological culture results. On the other hand, absence of these symptoms and signs did not exclude the presence of acute maxillary sinusitis. [source]
