Mean Time

Eustachian tube dysfunction is one of the well-known factors leading to development of chronic suppurative otitis media. Tube mucociliary transport is important for elimination of the inflammation products from the middle ear enabling recovery of the affected mucosa of the middle ear, local circulation and restoration of normal air pressure in the middle ear. The study was aimed at determining: 1. whether perforation site on the tympanic membrane influences tube mucociliary transport time in individuals with traumatic rupture of the eardrum; 2. possible time difference of tube mucociliary transport between group of patients with chronic suppurative otitis media and group of patients with traumatic rupture of the tympanic membrane; 3. possible time difference of tube mucociliary transport between chronic tubotympanic type of suppurative otitis media, so called tubotympanic otitis media and atticoantral type of chronic suppurative otitis media, the so called atticoantral otitis; 4. the association between the degree of defect of the tympanic membrane mucosa and time of tube mucociliary transport in each individual type of chronic suppurative inflammation of the middle ear. Eustachian tube mucociliary transport was studied in 16 patients with tubotympanic otitis, in 13 patients with atticoantral otitis and in 9 patients with traumatic rupture of the eardrum (control group of patients). All patients were treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia in Belgrade during 2002. Tube mucociliary transport was studied upon instillation of 10 ?l 5% sterile saccharine solution through the existing eardrum perforation in the course of preoperative preparation of the patient for surgical intervention. The time interval from the moment of sterile saccharine solution application till perception of the sweet taste in the mouth and pharynx was measured in studied patients. The obtained results were analyzed using the methods of descriptive and analytical statistics (t-test for small independent samples). The mean time of tube mucociliary transport in patients with traumatic rupture of the tympanic membrane was 7.6 minutes. The mean time of tube mucociliary transport in tubotympanic otitis with normal mucosa of the tympanic cavity promontorium was 15 minutes, while mean time of tube mucociliary transport in tubotympanic otitis with polypoid changes of the promontory mucosa was 24 minutes (t=5.218; p<0.01). Mean time of tube mucociliary transport in atticoantral otitis with normal promontory mucosa of the tympanic cavity was 35.5 minutes, while mean time of mucociliary tube transport in atticoantral otitis with polypoid changes of promontory mucosa was 48 minutes (t=6.99; p<0.01). In the irreversibly changed tympanic cavity mucosa, tube clearance saccharine test was negative even after one hour. The results of our study indicate the possibility that prolonged mucociliary tube transport has greater influence to development of atticoantral otitis rather than to development of tubotympanic otitis. The association between the degree of mucosal defect and time of mucociliary transport was evidenced in both types of chronic suppurative inflammation of the middle ear.

Direct Relation

This study was undertaken to clarify the relation between nasal allergy and otitis media with effusion and to observe histologically the allergic changes in the eustachian tube itself in animals. Allergic changes in the eustachian tube and tympanic cavity were clearly observed histologically when the antigen had been introduced into the tympanic cavity of sensitized guinea pigs. On the other hand, administration of the antigen into the nose produced marked allergic changes in the nose and pharynx but no change in the eustachian tube or tympanic cavity. In view of these findings, it is suggested that allergy of the nose bears little direct relation to that of the middle ear and the eustachian tube.

AbstractObjective:This study evaluated the relationship between radiation and Eustachian tube dysfunction, and examined the radiation dose required to induce otitis media with effusion.Methods:The function of 36 Eustachian tubes in 18 patients with head and neck cancer were examined sonotubometrically before, during, and 1, 2 and 3 months after, intensity-modulated radiotherapy. Patients with an increase of 5 dB or less in sound pressure level (dB) during swallowing were categorised as being in the dysfunction group. Additionally, radiation dose distributions were assessed in all Eustachian tubes using three dose–volume histogram parameters.Results:Twenty-two of 25 normally functioning Eustachian tubes before radiotherapy (88.0 per cent) shifted to the dysfunction group after therapy. All ears that developed otitis media with effusion belonged to the dysfunction group. The radiation dose threshold evaluation revealed that ears with otitis media with effusion received significantly higher doses to the Eustachian tubes.Conclusion:The results indicate a relationship between radiation dose and Eustachian tube dysfunction and otitis media with effusion.

The middle ear fluids of seven patients with bilateral, and five patients with unilateral serous otitis media (SOM), were demonstrated to be microbiologically sterile when assessed for the presence of bacteria, mycoplasma, viruses, and fungi. The concentrations of immunoglobulins G, M, A, D, and lysozyme (muramidase) were determined in the serum and middle ear fluids. Lysozyme levels of middle ear aspirates were found to be elevated in SOM patients. The elevated levels of lysozyme in combination with the antibody-containing classes of immunoglobulins may explain the microbiologically sterile condition of the middle ear fluids of SOM patients. Also, the elevated lysozyme concentrations in middle ear fluids may indicate the previous presence of neutrophils and hence a previous inflammatory insult. The increased levels of IgA demonstrated in middle ear fluids may indicate local synthesis of secretory IgA by secretory cells of Eustachian tube and middle ear. The closed Eustachian tube, partial vacuum conditions and absence of a portal of exit for accumulated serous fluids are offered as a possible explanation for SOM.
