Auditory Tube Dysfunction Occurring after Jaw Surgery

Abstract Background Orthognathic surgery is widely used in treating functional and skeletal problems. Any surgical procedure could cause side effects. Objectives This study aimed to evaluate the potential changes in orthognathic surgery on the hearing function of patients. Materials and methods Thirty-one orthognathic surgery candidates were recruited in this study. Patients underwent either single or double jaw surgery. Pure tone audiometry (PTA), tympanometry, and Eustachian Tube Dysfunction Test (ETFT) were performed postoperatively at 24 h, 6 weeks, and 6 months after surgery. Patients were tabulated based on the type of maxilla and mandibular surgical movements (vertical and horizontal). Results PTA evaluation, based on horizontal or vertical movements, did not show significant differences, although vertical movements resulted in less change in hearing threshold. In other words, no significant changes occurred in patients’ hearing threshold after surgery. No significant difference was also observed between horizontal and vertical movements in the results of tympanometry. Negative changes were found in the results of ETFT in vertical movements, which returned to pre-surgery values in the final test. Conclusions The risk of minor changes in hearing function is probable during the first week after orthognathic surgery, but these negative changes will either totally fade or remain negligible. Patients gave informed consent preoperatively, and reassurance postoperatively is prudent.

Tube Dysfunction

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.
