Sinusitis Otitis Media Suggested Reading

SUMMARY

Sinusitis occurs in both acute and chronic forms. The acute form is usually a result of bacterial complications secondary to a viral upper respiratory tract event. Approximately 1 in 200 viral upper respiratory tract events results in a secondary bacterial infection of the sinuses, with the ethmoids and maxillary deemed the most frequently involved. Chronic sinusitis may be a complication of repeated bacterial infections but more often than not appears to be a disease de novo characterized by an as yet undefined abnormality of the sinus mucosa. This predisposes to chronic infections.

Acute otitis media (AOM) is analogous to acute sinusitis in that it is a result of obstruction at the osteum of the eustachian tube. The bacteria responsible for AOM are similar to that responsible for acute sinusitis.

Allergic rhinitis is certainly a predisposing factor for AOM and probably a predisposing factor for sinusitis as well.

Key Words: Sinus ostia; eustachian tube; allergic rhinitis; nasal polyps; Streptococcus pneumoniae; Haemophilus influenzae; Moraxella catarrhalis.
