Alkaline pH in middle meatus in cases of chronic rhinosinusitis

Study type

Prospective and observational study.

Methods

The study group was divided in two groups consisted of 50 normal subjects (100 meati) and 50 patients (100 meati) of chronic rhinosinusitis (CRS). All subjects underwent nasal endoscopy along with measurement of the pH of the middle meatus using a portable pH monitoring device. Statistical analysis was done to compare mean pH of normal middle meatus with the diseased one.

Results

The mean pH of normal 100 middle meati was measured to be 7.35(± 0.82). The mean pH of 100 middle meatii in CRS patients was higher 7.81(± 0.83) and was found to be statistically significant (p = 0.00011).

Conclusion

Alkaline pH (7.81) was observed in the middle meatus of CRS patients.
