THE MERCK MANUAL, Sec. 7, Ch. 86, Nose And Paranasal Sinuses (Site not responding. Last check: 2007-10-07) |
 | | Acute sinusitis is caused by streptococci, pneumococci, Haemophilus influenzae, or staphylococci and is usually precipitated by an acute viral respiratory tract infection. |
 | | In acute sinusitis, penicillin V 250 mg po q 6 h is the initial antibiotic of choice, and erythromycin 250 mg po q 6 h is the second choice. |
 | | Sinusitis not responsive to antibiotic therapy may require an operation (maxillary sinusotomy, ethmoidectomy, or sphenoid sinusotomy) to improve ventilation and drainage and to remove inspissated mucopurulent material, epithelial debris, and hypertrophic mucous membrane. |
