Objective: To systematically identify the complications associated with balloon Eustachian tuboplasty and their frequency of occurrence. This study will also highlight the measures that can be employed to avoid these complications and perform this procedure more safely. Methods: Systematically reviewed relevant papers published until January 2023. Each reference was checked and evaluated for any potential manuscripts. There was no registered protocol; the Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used. Results: Sixty-nine publications were found, from which 14 publications met our inclusion criteria: 2 randomised clinical trials, 5 retrospective studies, 2 systematic reviews, 2 case series and 3 case reports. Studies with balloon Eustachian tuboplasty procedure only were included, regardless of ethnicity, gender and age. All studies were excluded in which more than one procedure was performed. Conclusion: Balloon Eustachian tuboplasty is a relatively safe procedure with an overall complication risk of 1.66 per cent. Major complication rate was 0.43 per cent. Surgical emphysema was the most common, around 0.40 per cent. [ABSTRACT FROM AUTHOR]

A transsphenoidal surgical (TSS) approach is used for pituitary gland surgery involving pituitary adenomas, as well as for the biopsy of various neurosurgical tumors. TSS, although a relatively safe procedure, can lead to complications like hypopituitarism, visual impairment, nasal septal perforation, diabetes insipidus, carotid artery injury, and cerebrospinal fluid (CSF) leaks. Aseptic meningitis is also one of the complications of this procedure with an incidence of 1-2%, presenting with symptoms similar to bacterial meningitis, but with a low-grade fever of <102 F or even apyrexia. Here, we present a rare case of aseptic meningitis due to CSF leakage, presenting after 20 years of endoscopic surgery. A ventriculoperitoneal shunt was placed to stem the leak after two unsuccessful attempts of endonasal repair. [ABSTRACT FROM AUTHOR]

Background: Otosclerosis is an osteodystrophy of the otic capsule and presents with progressive conductive hearing loss. Imaging studies, especially computed tomography (CT) and cone-beam CT, have gained increased relevance in the diagnosis of otosclerosis., Objective: This study investigated whether there is a correlation between the extent of otosclerosis in high-resolution or cone-beam CT and hearing loss in pure-tone audiometry., Materials and Methods: Based on an existing classification of otosclerotic foci, a classification was established. Preoperative CT scans of patients undergoing stapedotomy between 2015 and 2019 were evaluated and classified by two independent otorhinolaryngologists. The preoperative pure-tone audiograms were analysed and compared to the results of CT., Results: A total of 168 CT studies (i.e., 168 ears) in 156 patients with intraoperatively confirmed otosclerosis were included in our study. A correlation between the extent of the otosclerotic focus or the calculated scores and hearing loss in pure-tone audiometry (air conduction, bone conduction and air-bone-gap) could not be proven., Conclusion: Preoperative CT is not obligatory. However, preoperative imaging using CT or cone-beam CT can be helpful to confirm the diagnosis and exclude other middle or inner ear pathologies as well as in planning of the surgical procedure in the overall context of otoscopy and audiometry. A correlation with the degree of hearing impairment could not be demonstrated and remains unclear., (© 2022. The Author(s).)
