Does Successful Myringoplasty Affect Eustachian Tube Function?

Eustachian tube (ET) is a tube connecting the middle ear cavity with the nasopharynx and has an important role in equalization of pressure around TM. Many studies investigated the role of ET function tests on the results of myringoplasty/tympanoplasty. Our aim is to assess the effect of successful myringoplasty on Eustachian tube function. A prospective study included 37 patients admitted to the E.N.T Department at Sohag University Hospital in the period between March 2018 and March 2019 suffering from dry central perforation necessitating myringoplasty. Pre-operative E.T function tests using tympanometry and methylene blue dye test were done. Post-operative follow-up tympanometry was done after 3 months for those with successful myringoplasty and compared to the preoperative assessment. Thirty-one (83%) patients had functioning ET, 6 (17%) had non-functioning ET and 32 patients (86.5%) had successful myringoplasty (taken healthy graft). According to the effect of myringoplasty on ET function test 3 months following surgery, (9%) were affected, either improved (3%) or worsen (6%), while (91%) were not affected by tympanometry in those with taken healthy graft cases. In our study, there was no significant effect of myringoplasty on E.T function. Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-021-02534-8.

Surgical complications of cochlear implantation in a tertiary university hospital.

INTRODUCTION: Cochlear implantation remains a popular and effective therapy for patients with sensorineural hearing loss that not get benefit from conventional hearing aids Objective: To analyze the surgical complications obtained in patients that underwent cochlear implantation in a tertiary university hospital. MATERIALS AND METHODS: Retrospective analysis of the medical files of cochlear implant patients who underwent surgery at our institution between October 2014 and July 2016. This population comprised 163 patients (52.7% males and 47.3% females). Complications were classified in to 'major' and 'minor' complications depending on degree of management. RESULTS: Overall, the mean age at the time of implantation was 7.44 years. The cause of deafness was congenital in 81.6% of patients and acquired in 18.4% of patients. The overall complication rate was 10.43%, 3.68% being major and 6.75% being minor complications. The most common minor complication in our series was wound complications, and the most common major complication was device failure. Excluding device failures, the major complication rate was 1.84%. CONCLUSION: Cochlear implantation is a safe surgical technique for rehabilitation of patients with severe to profound hearing loss, associated with a low surgical complications rate. The majority of surgical complications can be managed with conservative measures or minimal intervention.
