RESUMEN
Congenital cholesteatoma is a rare, non-neoplastic lesion that causes conductive hearing loss in children. It is underrecognized and often diagnosed only when there is an established hearing deficit. In the pediatric population, hearing deficiency is particularly detrimental because it can impede speech and language development and, in turn, the social and academic well-being of affected children. Delayed diagnosis leads to advanced disease that requires more extensive surgery and a greater chance of recurrence. A need to promote awareness and recognition of this condition has been advocated by clinicians and surgeons, but no comprehensive imaging review dedicated to this entity has been performed. This review aims to discuss the diagnostic utility of high-resolution computed tomography and magnetic resonance imaging in preoperative and postoperative settings in congenital cholesteatoma. Detailed emphasis is placed on the essential preoperative computed tomography findings that facilitate individualized surgical management and prognosis in the pediatric population.

OBJECTIVE: The objective of this study was to evaluate the graft outcomes and iatrogenic cholesteatomas for 3 years following cartilage-perichondrium over-underlay technique with perichondrial graft covering the epithelium for large-sized tympanic membrane (TM) perforations. MATERIALS AND METHODS: This prospective case series enrolled patients with large-sized perforation who underwent endoscopic cartilage-perichondrium over-underlay technique. The graft success rate, hearing outcomes, and development of iatrogenic middle ear cholesteatomas and graft cholesteatomas were assessed at 3 years postoperatively. RESULTS: This study included 62 ears of 62 patients. The mean follow-up duration was 47.3 ± 10.8 (38-64) months. Neovascularization was observed in the lateral perichondrium graft in 55 (88.7 %) patients, which inosculated into the TM remnant at 4-5 weeks. However, graft neovascularization was not observed in the four patients with excessive perichondrium graft that migrated into the external auditory canal and the three patients with middle ear infections. The graft failure rate was 6.5 % at 6 months, 11.3 % at 12 months, 6.5 % at 24 months, and the overall graft success rate was 91.8 % at the last follow-up. Granular myringitis developed in 11.3 % (7/62) of the patients. High-resolution computed tomography revealed well-pneumatized mastoids and middle ear at the final follow-up. However, graft cholesteatomas were observed in 3 (4.8 %) patients at 7-24 months postoperatively. CONCLUSIONS: The cartilage-perichondrium over-underlay technique with perichondrial graft covering TM epithelium is safe and effective for the repair of large perforations, with good short- and long-term graft outcomes, minimal risk of graft cholesteatoma development, and no risk of iatrogenic middle ear cholesteatomas.

OBJECTIVES: To describe a rare complication of cholesteatoma. METHODS: Case report with literature review. RESULTS: We report a case of a 37-year-old male who presented for evaluation of otorrhea, headache, and progressive left sensorineural hearing loss. Clinical and radiologic evaluation demonstrated a large recurrent attic cholesteatoma with erosion into the lateral and superior semicircular canals, and diffuse enhancement of the internal auditory canal and cerebellopontine angle suggestive of hypertrophic pachymeningitis secondary to cholesteatoma. After treatment with a course of antibiotics and canal wall down mastoidectomy surgery for cholesteatoma exteriorization, he experienced improvement of his symptoms and resolution of hypertrophic pachymeningitis. CONCLUSION: Hypertrophic pachymeningitis is a rarely described complication of cholesteatoma. In the context of cholesteatoma, treatment with antibiotics and surgical removal or exteriorization of cholesteatoma are effective treatments for HP.

PURPOSE: To investigate the rate of residual disease in the Potsic staging system for congenital cholesteatomas. METHODS: A protocol registration was published on PROSPERO (CRD42022383932), describing residual disease as a primary outcome and hearing improvement as secondary. A systematic search was performed in four databases (PubMed, Embase, Cochrane Library, Web of Science) on December 14, 2022. Articles were included if cholesteatomas were staged according to the Potsic system and follow-up duration was documented. Risk of bias was evaluated using the Quality In Prognosis Studies (QUIPS) tool. In the statistical synthesis a random effects model was used. Between-study heterogeneity was assessed using I2. RESULTS: Thirteen articles were found to be eligible for systematic review and seven were included in the meta-analysis section. All records were retrospective cohort studies with high risk of bias. Regarding the proportions of residual disease, analysis using the χ2 test showed no statistically significant difference between Potsic stages after a follow-up of minimum one year (stage I 0.06 (confidence interval (CI) 0.01-0.33); stage II 0.20 (CI 0.09-0.38); stage III 0.06 (CI 0.00-0.61); stage IV: 0.17 (CI 0.01-0.81)). Postoperative and preoperative hearing outcomes could not be analyzed due to varied reporting. Results on cholesteatoma location and mean age at staging were consistent with those previously published. CONCLUSION: No statistically significant difference was found in the proportions of residual disease between Potsic stages, thus the staging system's applicability for outcome prediction could not be proven based on the available data. Targeted studies are needed for a higher level of evidence.

PURPOSE: In primary cholesteatoma patients, incus destruction with an intact and mobile stapes is a frequent finding. Different techniques have been described to restore the ossicular chain, including incus interposition, stapes augmentation and type III tympanoplasty. Controversy about postoperative hearing results in open versus closed surgical techniques exist. METHODS: We performed a retrospective analysis of clinical, surgical and audiometric data of patients with primary cholesteatoma surgery operated between 2010 and 2020, and a mobile stapes and one-stage ossicular reconstruction. Pre- and post-operative audiograms were compared for the different surgical groups, mainly focusing on postoperative air-bone gap. Mastoid pneumatization and ventilation was also considered. RESULTS: The mean postoperative air-bone gap (0.5-4 kHz) of the 126 included patients was 20 dB. Hearing after type III tympanoplasty (26 dB) was worse than incus interposition (19 dB) and stapes augmentation (20 dB). Hearing after an open (23 dB) versus closed (19 dB) surgical technique was significantly different. No improvement in air-bone gap was observed for the higher frequencies. CONCLUSION: A residual postoperative air-bone gap should be considered after primary cholesteatoma surgery with intact and mobile stapes. Incus interposition in closed cavity operation is the optimal situation, but open cavity surgery should not be avoided because of hearing. Extent of the disease is prioritized and poorer ventilation before and after surgery may affect postoperative hearing.

PURPOSE: Exploring a possible link between upper airway inflammation and the development of cholesteatoma by studying the association between mucosa-affecting diseases of the upper airways and cholesteatoma surgery. METHODS: This is a nationwide case-control study of 10,618 patients who underwent surgery for cholesteatoma in Sweden between 1987 and 2018. The cases were identified in the National Patient Register and 21,235 controls matched by age, sex and place of residency were included from national population registers. Odds ratios (OR) and corresponding 95% confidence intervals were used to assess the association between six types of mucosa-affecting diseases of the upper airways and cholesteatoma surgery. RESULTS: Chronic rhinitis, chronic sinusitis and nasal polyposis were more common in cholesteatoma patients than in controls (OR 1.5 to 2.5) as were both adenoid and tonsil surgery (OR > 4) where the strongest association was seen for adenoid surgery. No association was seen between allergic rhinitis and cholesteatoma. CONCLUSION: This study supports an association between mucosa-affecting diseases of the upper airways and cholesteatoma. Future studies should aim to investigate the mechanisms connecting mucosa-affecting diseases of the upper airways and cholesteatoma formation regarding genetic, anatomical, inflammatory and mucosa properties.

A cholesteatoma is an expansion of keratinizing squamous epithelium that enters the middle ear cleft from the outer layer of the tympanic membrane or ear canal. Choleatomas are always treated surgically. Recurrence of the illness presents another challenge for the patient and the surgeon, though. There have been reports of recurrence rates as high as 30% in adults and as high as 70% in children. Here, we describe a case of persistent recurrent otorrhea following revision surgery, along with acquired recurrent cholesteatoma following canal wall down surgery. A 38-year -male with underlying Diabetes Mellitus and Hypertension presented with left scanty and foul-smelling ear discharge for 2 years and left reduced hearing. He was diagnosed with left chronic active otitis media with cholesteatoma for which he underwent left modified radical mastoidectomy, meatoplasty and tympanoplasty in 2017. Five months post operatively, he presented with left otorrhea. However, he defaulted followed up and presented in April 2018 for similar complaints. Otoscopy examination revealed left tympanic membrane perforation at poster superior quadrant of pars tensa and bluish discoloration behind pars flacida. He was diagnosed as recurrent left cholesteatoma and subsequently he underwent left mastoid exploration under general anesthesia in June 2018. Postsurgery, he developed recurrent ear discharge which was treated with topical antibiotics and ear toileting. We report a case of recurrent Cholesteatoma despite canal wall down procedure requiring a second redo procedure and with persistent recurrent otorrhea after the redo procedure.However, this case demonstrates the need for regular follow ups even after a canal wall down procedure for detecting recurrence of disease. Moreover, this case denotes some of the patient factors and surgeon factors involved in disease recurrence. Furthermore, importance of opting for an imaging study in case of high suspicion of the disease.

OBJECTIVE: The aim of the study is to evaluate the application of high-resolution computed tomography (HRCT) and turbo spin-echo diffusion-weighted imaging (TSE-DWI) fusion imaging for localization of middle ear cholesteatomas. METHODS: Eighty-six patients with clinically suspected middle ear cholesteatomas were enrolled prospectively. Ear TSE-DWI and HRCT scans were performed using a postprocessing workstation to generate a TSE-DWI-CT fusion image. Subsequently, all the enrolled patients received surgical treatment. According to the STAM system (difficult access sites [S], the tympanic cavity [T], the attic [A], and the mastoid [M]), the agreement between the localization of lesions evaluated by HRCT, TSE-DWI, and TSE-DWI-CT fusion images and the intraoperatively recorded localization were computed using Cohen κ statistic. RESULTS: Based on the pathological results, the enrolled patients were divided into a cholesteatoma (n = 50) and a noncholesteatoma group (n = 36). The area under the receiver operator characteristic curve for diagnosis of cholesteatoma with TSE-DWI-CT fusion imaging was identical to that using the TSE-DWI images (0.924 vs 0.924, P > 0.05), but was significantly higher than that with HRCT imaging (0.924 vs 0.767, P = 0.0005). Furthermore, the diagnostic sensitivity and specificity of TSE-DWI-CT fusion imaging for cholesteatomas were 96.0% and 88.9%, respectively. Depending on whether the cholesteatoma extended to the mastoid, TSE-DWI-CT fusion imaging demonstrated good agreement with the intraoperative record for localization of lesions (κ = 0.808) and had a high accuracy of localization by the STAM system. CONCLUSIONS: Turbo spin-echo-DWI-CT fusion images have a very high diagnostic value for the preoperative localization of cholesteatomas.

BACKGROUND: There is ongoing debate over the optimal surgical approach for cholesteatoma treatment1-5. The aim of this review was to determine whether canal-wall down with mastoid obliteration is associated with favourable outcomes compared to either canal-wall down without obliteration or canal-wall up. The primary outcome was cholesteatoma reoccurrence with secondary outcomes including otorrhoea, reoperation and patient-reported outcome measures. METHODS: Medline, Embase, Cochrane databases and clinicaltrials.gov were searched for studies reporting outcomes of patients undergoing primary CWD-MO for cholesteatoma and directly compared with CWD and CWU mastoidectomies. Data were collated and meta-analysis performed. RESULTS: 2379 patients were included from 12 studies that met the inclusion criteria. CWD-MO was found to be associated with significantly less risk of recurrence when compared to CWU (OR = 0.330 (95 % CI 0.191-0.570, p < 0.001). When compared to CWD, CWD-MO was associate with significantly lower incidence of persistent otorrhoea (OR 0.405 (95 % CI 0.232-0.706, p < 0.001) while the rates of recurrence were comparable (OR: 1.231 [95 % CI: 0.550-2.757] p = 0.613). Otorrhoea rates between CWD-MO and CWU were equivalent as was reoperation. Quality of life and hearing outcomes were variably reported. CONCLUSIONS: This systematic review demonstrates that CWD-MO technique achieves lower recurrence rates comparable to CWD approaches and superior to CWU, while offering improved long-term control of otorrhoea. The final procedural choice should be decided based on surgeon experience, skill set and individual patient factors. To address the risk of selection bias, a randomised controlled trial is needed to answer this important research question.

PURPOSE: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model. MATERIALS AND METHODS: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups. RESULTS: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively. CONCLUSION: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas.

PURPOSE: To describe the presentation, diagnosis, and management of chronic otitis media recidivism after subtotal petrosectomy and ear canal closure (STP). MATERIALS AND METHODS: Patients with temporal bone pathology detected during follow-up after STP were identified in the electronic medical record. Pertinent clinical details regarding surveillance plan, presentation, imaging findings, and revision surgery were collected and analyzed. RESULTS: A total of 10 patients were identified with recurrent or persistent pathology after STP. The median time to detection was 46 months (IQR 24-84). Five patients (50 %) had non-specific symptomatology, 4 patients (40 %) were completely asymptomatic, and 1 patient (10 %) was asymptomatic outside of two instances of mastoiditis with cochlear implant device infection treated with incision and drainage. One patient (10 %) was noted to have proptosis on examination, but no other patients had objective signs of disease at detection of disease recidivism. Nine (90 %) patients had pathology identified on preoperative imaging. All patients underwent revision surgery, with identification of cholesteatoma in 8 cases (80 %) and cholesterol granuloma in 2 cases (20 %). Extensive disease was noted in 6 patients (60 %), all of whom followed-up greater than 3 years from surgery. All patients tolerated revision surgery without complication. CONCLUSIONS: Recidivistic disease often remains clinically silent for extended periods of time after STP. Planned follow-up - with imaging or second look surgery - to facilitate early detection should be considered. Undetected disease recurrence or development may result in morbidity in a proportion of patients if surveillance is not performed.

PURPOSE: To evaluate the effectiveness and safety of surgery for chronic otitis media in elderly patients, compared to younger adults and children. METHODS: Patients with chronic otitis media with and without cholesteatoma formation were assessed. Patients aged 65 years and older were included and compared to adults aged 35-55 and to children. Effectiveness was evaluated by comparing postoperative dry and safe ears in ages groups, safety was assessed by comparing postoperative adverse events. RESULTS: Postoperative success and adverse events did not differ between age groups. Children had more recurrent cholesteatoma than adults. No difference in recurrent cholesteatoma between adults was observed. CONCLUSION: Surgical treatment for chronic otitis media with and without cholesteatoma in elderly patients is safe and effective. Age has no influence on postoperative adverse events and treatment outcomes in chronic otitis media. Cholesteatoma recurrence was not different between adult age groups.

OBJECTIVE: Investigation of ossicular chain (OC) status before surgery is important for preoperative patient consultation. This research aimed to investigate the relationship between pre-operative audiometric values and intra-operative OC condition in a relatively large population of chronic otitis media (COM) surgeries. METHODS: In this descriptive-analytic cross-sectional study, we evaluated 694 patients who underwent COM surgeries. We analyzed pre-operative audiometric data and intraoperative findings including ossicular anatomy, ossicular mobility, and the condition of middle ear mucosa. RESULTS: The optimal cut-off values of pre-operative speech reception threshold (SRT), mean air-conduction (AC), and mean air-bone gap (ABG) for predicting OC discontinuity were 37.5 dB, 37.2 dB, and 28.4 dB, respectively. For the prediction of OC fixation, the optimal cut-off points of SRT, mean AC, and mean ABG were 37.5 dB, 40.3 dB, and 32.8 dB, respectively. The computing of Cohen's d (95 % confidence interval) demonstrated the greater mean ABG in ears with OC discontinuity in comparison with ears with normal ossicles in all types of pathologies. There was a descending trend of Cohen's d from cholesteatoma to tympanosclerosis and then to granulation tissue and hypertrophic mucosa. There was a substantial relation between the type of pathology and OC status (P < 0.001). Ears with tympanosclerosis plaque had the most fixed OC among all types of pathologies (40 ears, 30.8 %), and ears with no pathology had the most normal OC (135 ears, 83.3 %). CONCLUSIONS: The results supported the view that pre-operative hearing is a key determining factor for the prediction of OC status.

PURPOSE: The European and Japanese system for cholesteatoma classification proposed an anatomical differentiation in five sites. In stage I disease, one site would be affected and in stage II, two to five. We tested the significance of this differentiation by analyzing the influence of the number of affected sites on residual disease, hearing ability and surgical complexity. METHODS: Cases of acquired cholesteatoma treated at a single tertiary referral center between 2010-01-01 and 2019-07-31 were retrospectively analyzed. Residual disease was determined according to the system. The air-bone gap mean of 0.5, 1, 2, 3 kHz (ABG) and its change with surgery served as hearing outcome. The surgical complexity was estimated regarding the Wullstein's tympanoplasty classification and the procedure approach (transcanal, canal up/down). RESULTS: 513 ears (431 patients) were followed-up during 21.6 ± 21.5 months. 107 (20.9%) ears had one site affected, 130 (25.3%) two, 157 (30.6%) three, 72 (14.0%) four and 47 (9.2%) five. An increasing number of affected sites resulted in higher residual rates (9.4-21.3%, p = 0.008) and surgical complexity, as well poorer ABG (preoperative 14.1 to 25.3 dB, postoperative 11.3-16.8 dB, p < 0.001). These differences existed between the means of cases of stage I and II, but also when only considering ears with stage II classification. CONCLUSION: The data showed statistically significant differences when comparing the averages of ears with two to five affected sites, questioning the pertinence of the differentiation between stages I and II.

PURPOSE: Cholesteatoma is a rare middle ear pathology. It can be classified into acquired and congenital forms. Although benign, cholesteatomas can cause significant morbidity including hearing loss, infection, facial palsy and thrombosis. Congenital cholesteatomas are incredibly rare and bilateral disease has not commonly been published in the literature. METHOD: We describe the case of female identical (monozygotic, monochorionic, diamniotic) twins who both developed congenital cholesteatomas. In this report, we review the aetiology, treatment, embryology and pathology of cholesteatoma. RESULTS: The patients have been followed up 15 years after their initial surgery with promising results - pure-tone audiometry and repeat scans have not illustrated any disease recurrence. CONCLUSION: This paper presents one of the only cases of female monozygotic twins presenting with unilateral and bilateral cholesteatomas.

PURPOSE: Complete removal of the matrix over the existing fistula in the event of an extensive cholesteatoma with labyrinth invasion can result in total deafness. This study aimed to present a novel method of underwater endoscopic labyrinth dissection using continuous steroid irrigation (CSI) and systemic steroid administration for hearing preservation. METHODS: The endoscopic diving technique (EDT) was used to dissect semicircular canals, revealing the underwater anatomy of membranous labyrinth structures, in two cadaver temporal bones. EDT with CSI was used in three clinical cases with extensive cholesteatoma. RESULTS: On cadaver temporal bones, the anatomy of the lateral (LSC), superior (SSC), and posterior membranous semicircular canals with their respective ampullas and common crus was documented. In the first case managed with transcanal EDT, the LSC was eroded across almost its entire length. The fallopian canal was circumferentially eroded at the second genu and part of the mastoid segment. The cholesteatoma matrix was completely removed, and the membranous LSC was preserved. In the second and third cases, we were able to remove the cholesteatoma matrix along the eroded bony semicircular canals while keeping the membranes intact. No sensorineural hearing loss was detected in the postoperative masked pure-tone audiometry at a mean follow-up time of 12 months or cholesteatoma recurrence at the follow-up imaging. CONCLUSIONS: EDT with CSI can be safely utilized in the course of temporal bone labyrinth dissections and provides advantages during cholesteatoma removal over the eroded labyrinth on preservation of the membranous structures, and thus may help preserve cochlear function.

PURPOSE: To investigate the role of non-echo planar diffusion weighted imaging (DWI) using "periodically rotated overlapping parallel lines with enhanced reconstruction" (PROPELLER) sequence for the diagnosis of cholesteatoma compared to surgical and histopathological results in an attempt to determine the factors causing false negative and false positive diagnoses. METHODS: Patients who had PROPELLER DWI before ear surgery were retrospectively reviewed. The presence of a lesion with diffusion restriction on PROPELLER DWI was accepted as positive for cholesteatoma, and the results were compared to the intraoperative and histopathological findings. RESULTS: A total of 112 ears in 109 patients were reviewed. On PROPELLER DWI, a lesion with diffusion restriction was found in 101 (90.2%) ears, while in 11 (9.8%) of the patients, no diffusion restriction was found. Surgery and histopathological analysis revealed a cholesteatoma in 100 (89.3%) ears, while in 12 (10.7%) ears, no cholesteatoma was found surgically. There were 96 (85.7%) true positives, 7 (6.2%) true negatives, 5 (4.5%) false positives and 4 (3.6%) false negatives. The accuracy, sensitivity, specificity, positive predictive and negative predictive values of non-echo planar DWI were calculated to be 91.96%, 96%, 58.33%, 95.05%, and 63.64%, respectively. CONCLUSION: Non-echo planar DWI using PROPELLER sequence has high accuracy, sensitivity and positive predictive value and can be used for the detection of cholesteatoma. The external auditory canal, postoperative ears and small lesions should be evaluated with caution to avoid false results.

PURPOSE: To evaluate the efficacy of ossicular chain reconstruction (OCR) in primary and revision surgeries, and to investigate the impact of the number of previous surgeries on hearing outcomes. METHODS: Retrospective analysis of cases with OCR due to chronic otitis in a tertiary center between January 2018 and September 2021. RESULTS: Altogether, 147 cases of ossicle involvement were assessed. In 91.83% (n = 135) OCR was performed, 96.26% of them with titanium TORP/PORP (n = 130), two cases with autologous prosthesis and three with piston. Mean follow-up was 8.8 months. The ABG significantly improved in the total group (TORP/PORP) from a mean (SD) of 30.94 (15.55) to 19.76 (13.36) dB (p < 0.0001) with 60.86% success. The best results were achieved in primary OCR with PORP implantation without cholesteatoma (89.47%). Primary cases have a significantly higher success rate in contrary to revision surgeries (72.27%, vs. 52.00%, p = 0.032). The only relevant predictive factor proved to be the fact of revision (p = 0.029). A statistically significant correlation between the number of previous surgeries and hearing results could not be proved. There was no difference in hearing outcomes between patients with only one or more than one previous surgeries in the revision groups. Neither the presence of cholesteatoma, nor the type of OCR (TOPR/PORP) and the indication of revision had an impact on postoperative ABG. CONCLUSIONS: Titanium prostheses are effective in OCR both in primary and revision cases. It is not the number of previous surgeries, but the fact of revision that influences postoperative hearing results.

PURPOSE: Few data are available regarding subjective complaints and quality of life (QoL) after subtotal petrosectomy (STP). The purpose of our study was to assess long-term surgical results after STP, and to evaluate disease-specific, patient-reported outcomes including QoL and subjective hearing. METHODS: A retrospective cohort study, including a postal survey, was performed in the Amsterdam University Medical Centers (Amsterdam UMC) location Academic Medical Centre (AMC). All patients who underwent a STP between 1990 and 2018 were included. Patient characteristics, indication for surgery, adverse events, disease recidivism, and patient-reported health outcomes were evaluated. RESULTS: 181 patients (183 ears) underwent a STP for several indications. The main indication was chronic otitis media (COM) with or without cholesteatoma (69%). In the total cohort, 8 residual cholesteatoma (5%) and 6 inclusion cholesteatoma 4% were detected. Postoperative (functional) health outcomes showed a significant negative impact on QoL in the STP cohort compared to normative data. Compared to patients without ear problems, the postoperative STP patients scored worse on almost all domains of the Chronic Ear Survey (CES) (p < 0.001). SF-36 scores of postoperative STP data showed negative Z-scores in almost all subscales, indicating lower levels of QoL compared to Dutch reference values. Most subscales of the Amsterdam Inventory for Auditory Disability and Handicap (AIADH) demonstrate a large-effect size in disadvantage of the STP cohort when compared to Dutch reference values. CONCLUSION: STP is a suitable technique to tackle severe ear disease. Despite its favourable surgical results, STP has a negative impact on several domains of patient's QoL.

PURPOSE: To map healthcare utilized by subjects with chronic otitis media, with or without cholesteatoma and perform a cost analysis to determine key drivers of healthcare expenditure. METHODS: A registry study of 656 adult subjects with chronic otitis media that underwent a middle ear surgery between 2014 and 2018. Healthcare contacts related to all publicly funded specialist ENT care, audiological care and primary care for a disease of the ear and mastoid process were extracted. The data are extracted from the Swedish National Patient Registry on subjects that reside in western Sweden. RESULTS: Subjects made 13,782 healthcare contacts at a total cost 61.1 million SEK (6.0 million EUR) between 2014 and 2018. The mean cost per subject was 93,075 SEK (9071 EUR) and ranged between 3971 SEK (387 EUR) and 468,711 SEK (45,683 EUR) per individual. In the most expensive quartile of subjects, mean cost was 192,353 SEK (18,747 EUR) over the 5-year period. These subjects made 3227 ENT contacts (roughly four each year) and 60% of total costs were associated with in-patient ENT care. CONCLUSION: Patients with chronic otitis media are associated with high ENT resource utilization that does not diminish after surgical intervention and the disease places a long-term burden on healthcare systems. Significant costs are attributed to revision surgeries, indicating that these patients could be managed more effectively. In many such cases, reoperation cannot be avoided, especially due to recurrence of cholesteatoma. However, in some patients, when the indication for subsequent surgery is only hearing improvement, alternative options, such as hearing aids or implants, should also be considered. This is especially true in difficult cases, where revision ossiculoplasty is likely.
