Air Conduction

A comparison has been made of air conduction threshold changes up to 1 year after myringotomy, aspiration of middle ear fluid, and insertion of ventilation tubes in ten patients with bilateral and 12 with unilateral secretory otitis media (SOM). Pure tone air conduction thresholds have been analyzed in three frequency groups: Low frequency (LF; 0.25, 0.5, and 1 kHz), high frequency (HF; 2,4, and 8 kHz), and extra-high frequency (EHF; 10, 12, 14, and 16 kHz). In the LF and HF ranges, significant improvement came during the first 24 hours after intubation, while in the EHF range, threshold lowering occurred gradually over the following 2 months. Possible explanations for these findings are discussed.

Purulent Fluid

Most pediatricians recognize and treat acute otitis media several times each day. Yet there is wide disagreement about certain aspects of its diagnosis and treatment, despite a large and growing literature on the subject. This review attempts to summarize what is known about acute otitis media in children. DEFINITION Acute suppurative otitis media is distinguished from secretory (serous) otitis media by the presence of purulent fluid in the middle ear. Pathogenic bacteria may be cultured from the majority of needle aspirates of this purulent fluid. In secretory otitis media, relatively few polymorphonuclear cells are present in the middle ear fluid, which is either thin and straw-colored (serous) or thick and translucent grey (mucoid). The fluid has the chemical characteristics either of a transudate of plasma or of a mucoid secretion, presumably produced by goblet cells and mucous glands which are greatly increased in the middle ear mucosa of patients with secretory otitis media. Cultures of this middle ear fluid are usually negative for pathogenic bacteria and viruses. Suppurative otitis media can be diagnosed positively only by aspiration of purulent fluid from the middle ear, but this procedure is rarely necessary for initial diagnosis and management. Clinical findings helpful in distinguishing suppurative from secretory otitis media are discussed below. INCIDENCE In a study of 847 British children during the first five years of life, 19% had at least one episode of otitis media; one third of these had more than one episode. This was considered to be a minimal estimate in these children, since otorrhea was the chief criterion for diagnosis.

Middle Ear Pressure

Secretory otitis media, middle ear atelectasis, and retraction type cholesteatomas are the most frequently occurring chronic middle ear diseases; and eustachian tube obstruction and the generation of negative or less than atmospheric middle ear pressure is said to be an essential factor in the pathogenesis of these diseases. It has been found that habitual sniffing causes high degrees of negative middle ear pressure in diseased ears; this finding demonstrates eustachian tube patency rather than obstruction. Ears intubated for chronic secretory otitis media, middle ear atelectasis, and cholesteatoma were examined to identify patent eustachian tubes. More than one third of the patients aspirated a solution into the middle ear with one or more sniffs by aspirating air from their middle ears, demonstrating eustachian tube patency rather than obstruction.

Middle Ear Fluid

Data on 87 patients (113 ears) with chronic secretory otitis media (SOM) are reported. The bacteriological analysis of the middle ear fluid (MEF) revealed Streptococcus pneumoniae in 7% of ears, Hemophilus influenzae in 9%, opportunistic bacteria in 20%, while 64% of the samples showed no growth. Free capsular polysaccharide pneumococcal antigens were found in 5 % of the MEF samples using counterimmunoelectrophoresis (CIEP) with Omniserum containing 83 different pneumococcal polysaccharide types. Heating of the samples to disrupt the immune complexes increased the frequency of positive samples to 27%. These findings, together with the frequent occurrence of S pneumoniae and H influenzae in the nasopharynx, strongly support the opinion that chronic SOM in a considerable number of cases is an immune complex disease.
