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.

And Function

The structure and function of the ear are documented, along with congenital abnormalities. The function of the Eustachian tube and symptoms caused by a blocked or patulous tube are discussed, along with possible treatments. Acute otitis media and its complications and management are explored. Strategies for managing glue ear and chronic suppurative otitis media with and without cholesteatoma are investigated. Surgical intervention is highlighted. The condition of otosclerosis and its diagnosis and management options are listed.

<p class="abstract"><strong>Background:</strong> The study was undertaken to find out Eustachian tube function in safe type of chronic suppurative otitis media and to study the comparison of graft uptake in normal, partially impaired and grossly impaired Eustachian tube function in safe type of chronic suppurative otitis media.</p><p class="abstract"><strong>Methods:</strong> The present prospective study was conducted in the Department of Otorhinolaryngology and Head and Neck surgery, Sri Maharaja Gulab Singh Hospital, Jammu during the period from November 2016 to October 2017. Patients were diagnosed clinically and also audiometrically by pure tone audiometry and impedance audiometry. Eustachian tube function test- Toynbee test was done in all the patients.  </p><p class="abstract"><strong>Results:</strong> Out of 20 patients with normal Eustachian tube function, 19(95%) showed graft uptake. Out of 20 patients with partially impaired Eustachian tube function, 18 (90%) showed graft uptake. Out of 20 patients with grossly impaired Eustachian tube functions 13 (65%) showed graft uptake. Comparison of mean values of pre and post- operative air-bone (AB) gap with respect to normal, partially impaired and grossly impaired Eustachian tube functions is highly significant statistically with (p&lt;0.001).</p><p class="abstract"><strong>Conclusions:</strong> As seen in our study, functioning Eustachian tube is an important requirement for optimum outcome of myringoplasty. Testing the functions of Eustachian tube before surgery provides a possibility of predicting the possible outcome of myringoplasty or tymapanoplasty. This is also concluded that a partially functioning Eustachian tube should not be considered to be a contraindication to these surgeries as in many of these cases graft uptake and AB gap closure was good (90%).</p>
