Resistance To Penicillin

A total of 204 chronic middle ear effusions from 122 children have been studied. Bacteria were isolated from 30 effusions. The commonest species found were Strep. pneumoniae and H. influenzae. These are also the commonest organisms causing acute otitis media (AOM). A similar pattern of serotypes was also demonstrated. In vitro sensitivity testing showed that most of the organisms isolated were sensitive to most commonly-used antibiotics. The main exception was resistance to penicillin amongst strains of H. influenzae and Staph. aureus. It is suggested that some cases of chronic secretory otitis media (SOM) may arise as a result of incomplete resolution of AOM and that the use of penicillin to treat AOM may be one factor in this process.

Poor eustachian tube function plays a major role in the pathogenesis of chronic secretory otitis media. This is illustrated by epidemiologic studies of secretory otitis media and long-term studies of treated secretory otitis. Evaluation of hearing results demonstrate that effective preoperative and postoperative tubal function is highly important for good surgical outcome in cases of chronic otitis and cholesteatoma.

Gas Balance

The sequelae of secretory otitis media (SOM) were monitored in 72 adult patients with SOM who were followed up for an average of 33 months. It was found that SOM became chronic and retraction of the tympanic membrane appeared as a function of the pneumatization of the mastoid. Ears with poor pneumatization (less than 6 cm2) developed chronic SOM in 52.2% of cases, as compared with 20% in cases with well-pneumatized ears (6 cm2 and above). Atelectasis developed in 37.3% of poorly pneumatized ears, and in only 5.7% of well-pneumatized ears. These sequelae may therefore be linked pathogenetically to the extent of pneumatization, as both the SOM and the sequelae appeared many years after formation and maturation of the pneumatic system. This study supports other studies that view the mastoid pneumatic system as an organ, as a middle ear pressure buffer. Well-pneumatized ears rarely develop a negative pressure and are seldom associated with chronic sequelae. Ears with poorly pneumatized mastoids lack the physiological function of such a pressure buffer. Ears with a tendency to develop a negative gas balance, whether as a result of deficient ventilation or excessive diffusion, will therefore develop a negative pressure more readily when their pneumatic system is underdeveloped, and consequently will be more prone to develop chronic sequelae.

Serous Otitis Media

Serous otitis media is the most common cause of hearing impairment. The role of lymphatic obstruction in the pathogenesis of serous otitis media is significant. A method for removal of the human Eustachian tube specimen and two techniques for identification of Eustachian tube lymphatic capillaries are described. One involves the antemortem intratympanic installation of Berlin blue. The other utilizes electron microscopy. Lymphatic capillaries cannot be reliably differentiated from blood capillaries with the light microscope. With electron microscopy, lymphatic capillaries can be differentiated from blood capillaries by differences in the basement membrane. The lymphatic capillary has gaps in the basement membrane with large nuclei in the wall. A blood capillary has a continuous basement membrane and sometimes red blood cells can be identified in the lumen. Using these methods, Eustachian tube lymphatic capillaries in the human are described for the first time in this report.

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.
