Abstract Background The opioid epidemic is a significant public health crisis challenging the lives of North Americans. Interestingly, this problem does not exist to the same extent in Europe. Surgeons play a significant role in prescribing opioids, especially in the context of post-operative pain management. The aim of this study was to compare the post-surgical prescribing patterns of otologists comparing Canada and Austria. Methods An online questionnaire was sent to 33 Canadian and 32 Austrian surgeons, who perform otologic surgery on a regular basis. Surgeons were asked to answer some questions about their background as well as typical prescribing patterns for postoperative pain medication for different ear surgeries (cochlear implant, stapedotomy, tympanoplasty). In addition, surgeons were asked about the typical use of local anesthetics for pain control at the end of a procedure. Otologists gave an estimate how confident they were that their therapy and prescriptions provide sufficient pain control to their patients. Results Analysis of the returned questionnaires showed that opioids are more commonly prescribed in Canada than in Austria. Nonsteroidal anti-inflammatory drugs are used for postoperative pain more regularly after ear surgery in Austria, as opposed to Canada. Some of the prescribed drugs by European otologists are not available in North America. The use of local anesthetics at the end of surgery is not common in Austria. Surgeons´ confidence that the prescribed pain medication was sufficient to control postoperative symptoms was higher in the group not prescribing opioids than in the group that did routinely prescribe opioids. Conclusion Prescribing patterns differ substantially between the two evaluated countries. This data suggests an opportunity to reduce opioid prescriptions after otologic surgeries. Studies to evaluate pain after these operations as well as efficacy of analgesics following ear surgery are an important next step. Graphical abstract

Introduction. There are a few discussions regarding usefulness of an exoscope in otologic surgery compared to a traditional microscope. Objective. The pros and cons of using a newly developed exoscope (ORBEYE™) during microotologic surgery were evaluated. Methods. The usefulness of the ORBEYE™ exoscope was retrospectively assessed in 6 otologic surgeries by 8 surgeons postoperatively. A questionnaire comprising 20 questions was designed and used for evaluation. Results. All the otologic surgeons agreed that the exoscope is useful as an educational tool; the exoscope had the highest score in the questionnaire (average: 4.75). The question "Will the ORBEYE TM exoscope replace the conventional tympanoplasty or stapes surgery?" had the lowest score (average: 3.13). Conclusions. The quality of the images and movies in the exoscope was considered to be high and improved; therefore, the exoscope was considered as a useful educational tool in otologic surgery. Similar to otologic endoscopic surgery, all the members such as the operator and assistants could head up and share 1 image.

Objective: The main aim is to discuss the effect of nasal septal deviation on the postoperative hearing results of patients with tympanosclerosis., Material and Methods: We analyzed the hearing results of patients with tympanosclerosis who were operated on in a tertiary center. Pure tone audiometric results were compared according to the existence of nasal septal deviation., Results: This study included 48 patients with unilateral tympanosclerosis disease. Moderate or severe septal deviation had no significant effect on postoperative hearing results., Conclusion: The nasal septal deviation as the only pathologic factor in patients with tympanosclerosis did not have a deteriorating effect after surgery.

Background: Untreated traumatic tympanic membrane perforations (TMPs) may lead to permanent perforations and hearing loss. There are many materials that have been previously used for repairing the TMPs., Aims and Objectives: The purpose of this study is to evaluate the clinical and histological effects of Vivosorb (Vv) and Epifilm on healing of TMPs in a rat model., Material and Methods: The posterior-inferior quadrant of the tympanic membranes (TMs) in right ears of 14 rats was perforated using a 20-g needle and then the animals were randomly divided into 2 equal groups (n = 7). The perforated right TMs were treated with either Vv (Vv group) or Epifilm (Ep group). The left TMs of 7 rats were perforated in same way and allowed to close spontaneously without any topical material applications (spontaneous closure group as sham control, SC). The left tympanic membranes of the other 7 rats were not perforated and used as normal controls (NC group). On postoperative 15th day, tympanic bullas were extracted from killed rats and examined morphometrically and histopathologically., Results: Perforation closure rate was 85.7% (6/7) in both Vv and SC groups. Perforations of Ep group closed in 7/7 (100%) ears. The thicknesses of the perforated membranes were increased in SC and especially Vv groups. Also, connective tissue fibrosis, blood clots, and epithelial degenerations were detected in SC and Vv groups. The mean fibroblastic reaction scores of Vv, Ep, and SC groups were 2.14(+), 0.57(+), and 1.71(+) respectively, on comparison with NC group. The mean neovascularization score was 1.42(+) in Vv group, 0.14(+) in Ep group, and 0.57(+) in SC group., Conclusion and Significance: Vivosorb and especially Epifilm can improve the healing process in traumatic TMPs and additionally, Epifilm might be more preferred for the treatment of TMPs because of causing lesser fibrosis.
