“…In addition, endoscopic mucosal appearances do not always correspond to the histopathologic changes of the maxillary mucosa (Mann & Trong 1979; Kamel 1989; Stierna et al. 1991), and even the fact that the maxillary sinus in the healthy state is not sterile supports the discrepancy between endoscopic findings and mucosal pathology (Hartog 1997; Posawetz et al. 1991; Rong et al.…”

Although augmentation of the maxillary sinus floor with autogenous bone grafts has become a well established preimplantology procedure, its effect on the function of the maxillary sinus has not been the subject of prospective human studies. In this prospective study the effects of sinus floor augmentation on maxillary sinus performance were evaluated. Seventeen consecutive patients who were to undergo augmentation of the maxillary sinus floor with an iliac crest autogenous bone graft agreed to participate in this study. All patients were subject to (i) extensive anamnestic and clinical investigation on sinusitis, (ii) conventional radiography (Waters' projection) and (iii) unilateral endoscopic inspection of the maxillary sinus. This triad of evaluations was performed preoperatively, immediately preceding the augmentation procedure (the maxillary sinus to be inspected endoscopically was randomly selected), and at 3 (at insertion of the implants) and 9 months (at uncovering of implants) postaugmentation. None of the 17 patients showed clinical or radiological signs of actual sinus pathology preoperatively, though 5 patients had a history of an impeded sinus clearance. By contrast, unilateral endoscopic evaluation revealed pre-existing subclinical mucosal pathology in two out of five patients with a history of sinus clearance impairment and in one out of the other 12 patients. At 3 months' postaugmentation, clinical and radiographical examination showed chronic maxillary sinusitis in one non-compromised patient. Moreover, serial unilateral endoscopic evaluation revealed subclinical maxillary mucosal pathology in four other patients (two of whom had a history of an impeded sinus clearance), confirmed by Waters' projection in three of these four patients. At 9 months' postaugmentation, only subclinical maxillary mucosal pathology was detected endoscopically in two patients (one compromised, one non-compromised patient), confirmed by Waters' projection in this last patient. Five implants were lost during the 9-month observation period. As is obvious from this prospective evaluation, the effects of the augmentation procedure on maxillary sinus performance in patients without signs of maxillary sinusitis are of no clinical significance.

“…In this study, the 56.6 per cent positive culture rate of the swab specimens, and the 48.4 per cent rate of the mucosal specimens indicate that the endoscopically normal maxillary sinus is not sterile. However, this does not mean that the normal maxillary sinus is not sterile, although the endoscopically normal maxillary sinus was considered to be a healthy sinus (Posawetz et al, 1991).…”

“…Besides clinical history and radiological examination, endoscopy is another way to examine the disease status of the maxillary sinus. Posawetz et al (1991) denned healthy maxillary sinuses as present when the endoscopic findings of maxillary sinuses included normal mucosa and free sinus ostia. Bacteria were cultured from 75 per cent of swab specimens from their 16 endoscopically normal maxillary sinuses.…”

Bacteriology of endoscopically normal maxillary sinuses

The bacteriology of maxillary sinuses with normal endoscopic findings is reported in this study. When transantral sinoscopy was used to examine the maxillary sinuses, the whole maxillary sinus was inspected with different-angle endoscopes. If no lesion was seen over the whole maxillary sinus mucosa, no secretion existed in the maxillary sinus cavity, and the maxillary sinus ostium was wide open, the maxillary sinus was considered endoscopically normal. The bacteriology of these endoscopically normal maxillary sinuses was studied by passing cotton-tipped sticks through the cannula to collect swab specimens. In some cases, a biopsy forceps was also passed to obtain mucosal specimens. The specimens were sent to the laboratory for aerobic and anaerobic cultures. Between July 1990 and May 1998, 83 swab and 31 mucosal specimens were collected from 69 patients who had not taken any antibiotic within 10 days before endoscopy. The culture rates were 62.3 per cent (35/53) from swab specimens and 57.1 per cent (eight out of 14) from mucosal specimens in patients with the diagnosis of chronic paranasal sinusitis, and were 46.7 per cent (14/30) from swab specimens and 41. 2 per cent (seven out of 17) from mucosal specimens in patients without this diagnosis. This study shows that endoscopically normal maxillary sinuses are not sterile.

“…In our material, the flora was exclusively aerobic in 36.8%, anaerobic in 10.5%, and mixed in 52.6% of cases. Posawetz et al 49 notice that anaerobic bacteria in health should not prevail over aerobic. The claim by Kalcioglu et al 50 that the carrier of Alloiococcus otitidis may be useful in identifying patients being predisposed to sinusitis development, however interesting, seems doubtful.…”

Objective: The aim of the present study is to determine and compare the range of pH value in nasal and sinus cavities in vivo regarding the presence of bacteria colonizing sinonasal mucosa among healthy subjects. Methods: The nasal pH value measurement using a portable pH meter (Dx-pH System, Restech) and the microbiological culture swab were taken from beneath the middle turbinate and in the sinus cavity in 39 healthy subjects during maxillary bone corrective osteotomy with the Le Fort I technique. Results: The mean pH value (independently of sex, P = .441) in the healthy sinus cavity was statistically higher than in the nasal middle meatus: 7.96 (SD ± 0.29) versus 7.83 (SD ± 0.30) ( P = .032). Forty-eight strains of bacteria were cultured from sinus maxillaries cavities—aerobic 36.8%, aerobic and anaerobic 52.6%, anaerobic only 10.5%—and 23 strains from the nasal meatus—aerobic 25%, aerobic and anaerobic 75%. A statistically significant correlation was found between the type and location of 8 microorganisms, especially Propionibacterium acnes, identified only in the sinus cavities. Conclusions: Differences in the pH value between the middle nasal meatus and the maxillary sinus are characteristic of healthy subjects and could be associated with the diverse bacterial flora. The role of bacteria Propionibacterium acnes seems to be crucial for the pH range and sinus flora in healthy subjects.
