Auditory tube dysfunction in children (literature review, part 1)

AbstractObjective:We report three cases of recurrent, unilateral facial palsy associated with air travel.Method:The three cases are presented, along with a brief literature review concerning barotrauma and its association with air travel and facial palsy.Results:All three patients experienced unilateral facial paralysis during air travel, accompanied by additional symptoms which varied between cases. Symptoms resolved spontaneously in all cases. Two patients received ventilation tube insertion to prevent further recurrence. Computed tomography scanning revealed no bony defect in two patients, while the third exhibited dehiscence of the facial canal which may have contributed to the condition.Conclusion:Available evidence suggests that eustachian tube dysfunction can contribute to increased pressure within the middle ear, leading to neuropraxia of the facial nerve. Cases of facial paralysis associated with air travel are under-reported. Since there is no evidence-based management protocol for this condition, further investigation of its pathology is encouraged in order to improve our understanding.

In this study it has been studied the functional status of the middle ear, depending on the pathology of the tonsils of the pharynx. There has been discovered the dependence of the auditory tube dysfunction, the presence of the nosological form of the disease and age of the children. The highest risk of severe obstruction of the auditory tube exudate with persistent tympanic cavity is installed in infants with associated hypertrophy of the tonsils of the pharynx.

Tube Function

Background: Auditory tube dysfunction is suspected as primary cause of chronic otitis media and leads to surgical related complications in otitis media with tympanic membrane perforation. The diagnosis of eustachian tube malfunction is essential to know the pathogenesis of chronic otitis media.Methods: A total 150 cases and 75 age, sex matched control subjects between age group 20-50 years were selected. Pre and post-surgical history was noted and detailed ear examination, tympanometry was done. Auditory tube function was evaluated through Valsalva test, nasopharyngoscopy, pneumatic otoscopy. Intact tympanic membrane was assessed by Williams test, perforated tympanic membrane by Toynbee’s test. Results: Postoperative assessment of eustachian tube function by Toynbee’s test for 19 cases with failed tympanoplasty showed normal ET function in 5 cases, 8 cases had partial and 6 cases had gross ET dysfunction. Postoperative assessment ET function by William’s test showed 4 cases among 19 cases had partial ET dysfunction and 01 cases had gross ET dysfunction.Conclusions: Efficient surgical outcome of middle ear complications always depends on eustachian tube function. Most of the cases with residual CP showed partial or gross ET dysfunction. Patients with tubal dysfunction should be evaluated for underlying cause and treatable causes should addressed before proceeding for surgery as it increases the success rate of tympanoplasty.
