Effects of Tranexamic Acid on Intraoperative Bleeding and Surgical Field Visualization During Middle Ear Surgery: A Narrative Review.

Tranexamic acid is an antifibrinolytic agent widely used in several surgical procedures to reduce intraoperative bleeding. Intraoperative bleeding is a crucial problem for the ear surgeon, as it prevents good visualization of the surgical field. The aim of this work was to analyze the relevant literature about the use of tranexamic acid in ear surgery. A literature search was conducted in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement, across 3 databases (Medline, Cochrane, and Google Scholar), with the terms "tranexamic acid," and "ear," and "surgery." Three prospective, randomized, and double-blind clinical trials met the inclusion criteria. Studies were not able to be pooled because of heterogeneity in material, methods of delivery and evaluation, and procedures used. Despite these limitations, all 3 papers found a significant reduction in intraoperative bleeding, allowing a better visualization of the operating field. Despite the scarcity of published trials, tranexamic acid is safe and seems to be useful in reducing intraoperative bleeding in ear surgery, thus improving operative field visualization.

Otosclerosis online: a critical analysis of quality, reliability, readability and content of otosclerosis information.

PURPOSE: Several therapeutic options are usually discussed for otosclerosis management. Patients seek medical advice from an ENT specialist but are also increasingly using the internet for medical issues. This study intends to assess readability and quality of websites with information on otosclerosis. MATERIALS AND METHODS: This is a cross-sectional study performed in a tertiary care centre. The results of the first two pages of a Google search with the keyword "otosclerosis" were reviewed by two independent investigators. Readability was assessed with the Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease Score (FRES) and Gunning Fog Index. For quality and reliability assessment, the 16-item DISCERN instrument was used. Spearman's coefficient was used for correlations, and multivariate analyses of variance were used to assess differences. Inter-rater agreement was evaluated with concordance correlation coefficient. RESULTS: 18 websites were included. Two websites (11.0%) were authored by academic institutions, 5/18 (28%) by government agencies, 6/18 (33%) by professional organisations and 5/18 (28%) were medical information websites. The mean DISCERN score of the 18 websites was 40.8 ± 6.7/80 (range 28.7-51.7), corresponding to "fair" quality. The mean FRES score was 43.27 ± 10.6, and the mean FKGL was 11.43 ± 2.30, corresponding to "difficult to read". The mean Gunning Fog index was 12.90 ± 2.19 (range 9.81-18.20), corresponding to a "college freshman" level. CONCLUSIONS: This study shows that internet information on otosclerosis has an overall low readability, while the quality is heterogeneous and varies from "poor" to "good". Efforts should be made to improve the readability of otosclerosis websites.

Comparison of dislocation rates of Teflon and Titanium stapes prostheses: a retrospective survival analysis on 855 patients.

BACKGROUND: Stapes prosthesis dislocation is the first cause of revision stapes surgery. To our knowledge, there is no data about stability of the incus attachment of manual crimped prosthesis of different materials. This study aimed to compare the dislocation incidence between titanium and fluoroplastic stapes prostheses. METHOD: A monocentric retrospective cohort study was conducted between January 2013 and June 2022 in a tertiary-care center. All patients that underwent a primary stapes surgery with manually crimped fluoroplastic or titanium prostheses were included. Prosthesis dislocation from the incus was identified intraoperatively or with CT scan. The incidence of stapedial prosthesis dislocation over time was estimated using the Kalbfleisch and Prentice survival analysis method. Other indications for revision surgery prior to prosthesis dislocation were considered as competing events. Differences in the cumulative incidence functions between the fluoroplastic group and the titanium group was assessed using the Gray's test. RESULTS: Eight hundred and fifty-five patients underwent primary stapes surgery during the study period. Fluoroplastic prosthesis was used in 758 (88.7%) cases and titanium prosthesis in 97 (11.3%) cases. Median follow-up was 51.7 months (28.4-80.1). Dislocation was observed in 23 (3.0%) patients with fluoroplastic prosthesis and none (0.0%) in the titanium group. The probability of prosthesis dislocation at two years after surgery was 3.5% in the Teflon group and 0.0% in the Titanium group. No significant difference was found in the cumulative incidence of prosthesis dislocation between the fluoroplastic group and the titanium group (p = 0.12). CONCLUSIONS: Despite lack of statistical power, our results suggest a trend in a more stable incus attachment of manually crimped titanium stapes prosthesis compared to fluoroplastic over time. Further prospective randomized studies could be valuable to assess our findings.

French adaptation and validation of the Chronic Otitis Media Questionnaire-12 (COMQ-12).

OBJECTIVE: Chronic otitis media (COM) can seriously impact quality of life (QOL). Disease-specific questionnaires are essential for an accurate assessment of this impact. There is no questionnaire available for French-speaking patients with COM. This study aims to adapt and validate the French version of the COMQ-12 questionnaire. DESIGN: This is a controlled, prospective study, conducted between May 2020 and December 2021. Translation was performed using a forward-backward technique, and statistical validation was performed with a COM patients and a controls adult cohorts. STUDY SAMPLE: 100 patients (mean age 48 ± 16), and 50 controls (mean age 41 ± 16; p = 0.02) completed the test. RESULTS: Internal consistency, assessed by Cronbach's alpha, was 0.870 for the cases group. The mean COMQ-12 total score was 23.92 ± 11.3 for cases versus 3.70 ± 6.15 for controls (p < 0.0001). Individual items all had high discriminatory performances. The three items concerning ear discharge (Q1, Q2, Q9) had weaker correlation with the other items and the global score, but did not have a negative impact on internal consistency. CONCLUSION: The French version of the COMQ-12 is a short and easy-to-use test, with robust statistical properties, for assessing QOL in patients with COM.

MRI characteristics of intralabyrinthine schwannoma on post-contrast 4 h-delayed 3D-FLAIR imaging.

PURPOSE: The purpose of this study was to describe the MRI characteristics of intralabyrinthine schwannoma (ILS) on post contrast three-dimensional (3D) fluid-attenuation-inversion-recovery (FLAIR) images obtained four hours after intravenous administration of a gadolinium-based contrast agent (4h-3D-FLAIR). MATERIALS AND METHODS: This IRB-approved retrospective multi-center study included patients presenting with typical ILS from January 2016 to October 2020. All medical charts were systematically collected. All MRI examinations, including 4h-3D-FLAIR images, were reviewed by two board-certified neuroradiologists. Main outcome measures were location, signal intensity and associated anomalies of ILS. RESULTS: Twenty-seven out of 8730 patients (0.31%) referred for the investigation of a cochleovestibular disorder had a final diagnosis of ILS. There were 13 men and 14 women with a mean age of 52 ± 17 (SD) years (age range: 20-86 years). The most common clinical presentation was unilateral progressive sensorineural hearing loss (16/27; 59%). All ILS were unilateral and 15 (15/27; 55%) were intracochlear. All ILS presented as a hypointense filling defect within the labyrinth on T2-weighted images that enhanced on post-contrast T1-weighted images. On 4h-3D-FLAIR images, all ILS presented as a hypointense filling defect, associated with diffuse perilymphatic hyperintensity. Two patients (2/27; 7%) presented with ipsilateral endolymphatic hydrops. CONCLUSION: ILS displays consistent features on post-contrast 4h-3D-FLAIR images. ILS should not be confused with endolymphatic hydrops and requires a systematic analysis of the corresponding T2-weighted images.

IgG4-related pachymeningitis and mastoiditis, associated with cerebral venous thrombosis: A case report.

IgG4-related disease (IgG4-RD) is a multisystem fibroinflammatory condition; this can be a challenging diagnosis that requires clinico-pathologic correlation. We report a young woman, presenting with cranial nerve palsy. The work-up revealed pachymeningitis, cerebral venous thrombosis (CVT), and a destructive lesion in the mastoid. We diagnosed IgG4-RD through mastoidectomy. Thus, a biopsy of asymptomatic, infrequently affected organs, like the mastoid, can meet all histopathological criteria. In neuro-meningeal presentations, CVT may be secondary to the local inflammatory environment of pachymeningitis. Since our patient had a deep vein thrombosis one year prior, we discuss a possible higher risk of thrombosis in IgG4-RD patients.

Malleostapedotomy for otosclerosis, our experience of nitinol piston on twelve patients.

OBJECTIVE: Malleostapedotomy allows to completely by-pass the incus in otosclerosis surgery. Recently its use has been rivaled by hydroxyapatite cement for cases of mild and moderate necrosis of the incus. However, it remains gold standard for cases of extensive necrosis, incus dislocation, or epitympanic fixation. Modern heat-crimping pistons make surgery easier and safer. This study focuses on our experience with this technique. METHODS: Retrospective analysis of patient's files and pre- and post-operative audiograms, for cases of surgically treated otosclerosis with malleostapedotomy. RESULTS: Twelve patients underwent malleostapedotomy for otosclerosis between 2011 and 2019. Amongst them there were 10 revision surgeries and 2 primary cases. 75% had incus long-process necrosis, 17% had epitympanic fixation and one had a history of incus transposition. Nine patients (75%) had closure of air-bone gap (ABG) of <10 dB (p < 0.001) and 11 (92%) had a threshold of 20 dB (p < 0.001). Mean pre-operative ABG was 31 dB (15 dB-55 dB), and mean post-operative ABG was 7 dB (0 dB-21 dB; p < 0.001). There was no sensorineural hearing loss nor any other post-operative complication. CONCLUSIONS: Malleostapedotomy is a safe and reliable technique, allowing an ABG closure comparable to conventional incus to vestibule prosthesis. It remains the preferred technique whenever the incus cannot be used.

A Rare Cause of Stapedotomy Failure: When the Depth Marker Becomes a Locking Device: A Report on 2 Cases.

We report 2 cases of stapes surgery failure due to the depth marker groove of the piston of a Big Easy titanium prosthesis getting caught at the edge of the stapedotomy hole. In the first case, the stapedotomy failure, detected peroperatively, was corrected by modifying the angulation of the shaft of the prosthesis. In the second case, the failure occurred after a delay during which scar tissue developed around the depth marker groove, hampering the movement of the prosthesis. The usual postoperative imaging did not detect this complication. The diagnosis was made during revision surgery and the condition was treated by enlarging the hole in the footplate. Alternatively, the use of a piston without a depth marker groove would have resolved the problem. Although a rare event, the possibility of stapes surgery failure due to the depth marker groove should not be overlooked.

Transcutaneous Baha Attract system: Long-term outcomes of the French multicenter study.

BACKGROUND: Bone conduction implants based on abutment-driven acoustic transmission result in good hearing outcomes; however, skin complications impact the quality of life (QOL) and possibly the viability of the device for many patients. The transcutaneous magnetic Baha® Attract technology was developed with the goal of minimising skin complications. OBJECTIVES: To analyse surgical, auditory and QOL outcomes for patients implanted with the Baha® Attract. DESIGN: Prospective multicentre cohort study. SETTING: Four French tertiary referral centres. PARTICIPANTS: Thirty-two patients implanted with the Baha® Attract, including 25 with conductive and mixed hearing loss and 7 with single-sided deafness. MAIN OUTCOME MEASURES: Postoperative follow-up involved the visual analysis of soft tissue adaptation and sound processor magnet strength measurement. The audiometric outcomes were evaluated in quiet and noise, and the QOL was assessed using three different questionnaires. RESULTS: After 12 months of use, soft tissue was thinner, and mean magnet strength was significantly decreased (3.7-3.1, P < 0.05) relative to measures during surgery. The speech recognition threshold in quiet significantly improved compared to unaided situation (73-44 dB HL respectively, P < 0.001) as did functional gain in noise (+2.8). All QOL scores improved, and the APHAB questionnaire score correlated with the audiometric outcomes. CONCLUSIONS: The Baha® Attract technology results in significant hearing gain and improves QOL. Skin complications were not observed, although surgeons, audiologists and patients should be aware of soft tissue evolution during the first postoperative year. The reversibility of this implant is a major advantage that allows switching to another system if hearing degrades.

Chronic otitis media with effusion in chronic sinusitis with polyps.

The relationship between otitis media with effusion (OME) and chronic rhinosinusitis with nasal polyposis (CRSwNP) remains unclear. We conducted a cross-sectional study of 80 consecutively presenting patients-42 males and 38 females, aged 15 to 76 years (median: 48)-who were diagnosed with CRSwNP. Our aim was to ascertain the prevalence of OME in CRSwNP patients, to determine whether the severity of CRSwNP affected OME, and to identify risk factors for OME in CRSwNP patients. The severity of CRSwNP was assessed on the basis of nasal symptoms, endoscopic nasal examinations, and Lund-Mackay staging scores. In addition to demographic data, we obtained information on each patient's history of otitis, otoscopic findings, and the results of pure-tone audiometry and tympanometry. We then compared the data between CRSwNP patients with OME (n = 20) and those without (n = 60). In the OME group, a conductive hearing loss was present in 16 patients (80.0%); all patients in the control group had normal hearing. With regard to symptoms, only rhinorrhea appeared to be more common in patients with OME than in those without, although the difference was not statistically significant. We found no significant difference in nasal polyposis grades between the two groups. Also, we found no correlations between the risk of OME and previous surgical treatment, asthma, allergy, aspirin intolerance, aspirin and/or NSAID intolerance, aspirin and/or sulfite intolerance, and aspirin-exacerbated respiratory disease. Based on our findings, we conclude that OME occurs frequently during the evolution of CRSwNP, even when the nasal disease is well controlled. This finding suggests the possible presence, in OME and/or CRSwNP, of a global inflammatory process that involves the epithelium in both the middle ear and upper airway.

Otitis Media with Effusion Revealing Underlying Meningioma.

Otitis media with effusion (OME) is a very common condition in the current clinical practice. Usually idiopathic, it may sometimes be the consequence of primary diseases. Extracranial meningioma is rare, and even more when involving the ear and temporal bone. We report a case of temporal meningioma spreading to the middle ear and mastoid presenting as an OME. The diagnosis relies on a thorough imaging evaluation with computed tomography and magnetic resonance imaging. This short report aims to warn the otolaryngologist of this rare situation to prevent any delay in diagnosing and managing such a condition.

Cartilage Ossiculoplasty from Stapes to Tympanic Membrane in One-Stage Intact Canal Wall Tympanoplasty for Cholesteatoma.

OBJECTIVE: To report hearing results of cartilage interposition ossiculoplasty in one-stage intact canal wall (ICW) tympanoplasty for cholesteatoma with intact stapes. MATERIALS AND METHODS: A retrospective study of pre and postoperative hearing status was conducted at a tertiary referral otologic center in a series of 61 patients having undergone one-stage ICW tympanoplasty for cholesteatoma with intact stapes and cartilage ossiculoplasty during the same procedure. RESULTS: In the preoperative period, the mean air conduction thresholds (AC), air-bone gap (ABG), and speech reception thresholds (SRT) were 35.3, 20.14, and 35.6 dB, respectively. Postoperatively, with a mean follow-up of 29 months, AC, ABG, and SRT were 27.8, 13.34, and 28.8 dB, respectively. Mean hearing gain was 6.8 dB and mean SRT improvement was 6.8 dB. Mean bone conduction thresholds for 1, 2, and 4 kHz remained stable after surgery (17.6 dB preoperatively vs. 18 dB postoperatively). CONCLUSION: Cartilage ossiculoplasty from stapes to tympanic membrane in one-stage ICW tympanoplasty for cholesteatoma is a safe, reliable, easy, and effective procedure, with no additional cost.

Early Postoperative Imaging of the Labyrinth by Cone Beam CT After Stapes Surgery for Otosclerosis With Correlation to Audiovestibular Outcome.

BACKGROUND: Sensorineural complications of stapes surgery are rare but potentially serious. Imaging is usually performed to identify an underlying cause, such as excessive intravestibular penetration of the prosthesis or pneumolabyrinth suggesting perilymphatic fistula. Unfortunately, there is very little data in an unselected series of uneventful patients.The aim of this study was to analyze the depth of prosthesis penetration within the vestibule and the rate of pneumolabyrinth the day or the day after the procedure by performing a cone beam computed tomography of the temporal bone in a cohort of unselected patients, and to correlate imaging findings to clinical outcome. METHODS: A prospective monocentric study was conducted in a tertiary referral medical center. A cone beam computed tomography was performed in 80 consecutive patients having undergone stapes surgery for otosclerosis, the day or the day after the procedure. Penetration length and location of the prosthesis within the vestibule, as well as presence or absence of a pneumolabyrinth, were recorded, and compared with clinical data (vertigo, nystagmus, hearing measurement). RESULTS: Pneumolabyrinth was found in 15% of the patients. The mean penetration length of the prosthesis within the vestibule was 1 mm (0-1.9 mm). No serious complication occurred during the study period. No correlations were found when comparing imaging findings to clinical outcome. CONCLUSION: Our results do not support empirically insights into detrimental effects of postoperative pneumolabyrinth or too long prosthesis after stapes surgery. Further studies are needed to better understand the causes of postoperative complications of stapes surgery.

Stapedectomy in children: causes and surgical results in 35 cases.

OBJECTIVES: To study children who had undergone stapedectomy at an age younger than 16 years to determine the causes (particularly frequency of congenital anomalies vs otosclerosis) and to analyze the functional results over the short-term, 1-year, and long-term postsurgery time course. DESIGN: Ten-year retrospective study covering 1998 to 2008. SETTING: Pediatric tertiary care centers. PATIENTS: A total of 33 patients (35 ears) underwent stapes surgery from October 1998 to October 2008. MAIN OUTCOME MEASURE: Sex, age, preoperative and postoperative audiometric test results, associated anomalies, type of surgery (stapedotomy or partial stapedectomy), method of stapes surgery, and complications. RESULTS: The median age of patients at surgery was 13.4 years, ranging from 3.3 to 15.9 years. The major cause, which was found in 25 of 35 ears (71%), was nonprogressive conductive hearing loss due to congenital stapes fixation. The second most common cause, which was found in 6 of 35 ears (17%), was otosclerosis with progressive conductive or mixed hearing loss. Three ears presented posttraumatic stapes luxation (1 child aged 3.3 years at surgery). In 1 ear, the cause was osteogenesis imperfecta. Twenty-two ears were treated via the drill or laser-assisted small fenestra technique, and 13 ears were treated by a partial removal of the footplate covered by fascia. Early functional results were good, with a median postoperative air-bone gap of 9.8 dB, and 94% of the results were considered good or very good. There was no significant difference between early, 1-year, and longer-term audiometric results. CONCLUSIONS: Congenital fixation is the major indication for stapedectomy in children younger than 16 years. Functional results are good and remain stable over time.
