The existence of acquired cholesteatoma has been recognized for more than three centuries; however, the nature of the disorder has yet to be determined. Without timely detection and intervention, cholesteatomas can become dangerously large and invade intratemporal structures, resulting in numerous intra- and extracranial complications. Due to its aggressive growth, invasive nature, and the potentially fatal consequences of intracranial complications, acquired cholesteatoma remains a cause of morbidity and death for those who lack access to advanced medical care. Currently, no viable nonsurgical therapies are available. Developing an effective management strategy for this disorder will require a comprehensive understanding of past progress and recent advances. This paper presents a brief review of background issues related to acquired middle ear cholesteatoma and deals with practical considerations regarding the history and etymology of the disorder. We also consider issues related to the classification, epidemiology, histopathology, clinical presentation, and complications of acquired cholesteatoma and examine current diagnosis and management strategies in detail.
This article summarizes the existing theories and provides conceptual insights into the etiopathogenesis of acquired cholesteatoma, with the aim of stimulating continued efforts to develop a nonsurgical means of treating the disorder.
Identification of the CTS correlates in younger group would be of greater value in timely detection and treatment for these diseases. Correcting these disorders may aid in removing possible causes of CTS. This is the first report on the effect of aging on probable CTS risk factors. How factors associated with aging contribute to the development of CTS remains to be determined.
The aim of this study was to review recent advances in the management of acquired cholesteatoma. All papers referring to acquired cholesteatoma management were identified in Medline via OVID (1948 to December 2013), PubMed (to December 2013), and Cochrane Library (to December 2013). A total of 86 papers were included in the review. Cholesteatoma surgery can be approached using either a canal wall up (CWU) or canal wall down (CWD) mastoidectomy with or without reconstruction of the middle ear cleft. In recent decades, a variety of surgical modifications have been developed including various "synthesis" techniques that combine the merits of CWU and CWD. The application of transcanal endoscopy has also recently gained popularity; however, difficulties associated with this approach remain, such as the need for one-handed surgery, the inability to provide continuous irrigation/suction, and limitations regarding endoscopic accessibility to the mastoid cavity. Additionally, several recent studies have reported successes in the application of laser-assisted cholesteatoma surgery, which overcomes the conflicting goals of eradicating disease and the preservation of hearing. Nevertheless, the risk of residual disease remains a challenge. Each of the techniques examined in this study presents pros and cons regarding final outcomes, such that any pronouncements regarding the superiority of one technique over another cannot yet be made. Flexibility in the selection of surgical methods according to the context of individual cases is essential in optimizing the outcomes.
Simple sinusectomy is an adequate surgical technique for preauricular sinuses with a mild inflammatory condition. For more severe cases, the figure 8 incision with extended fistulectomy can achieve adequate wound exposure for radical excision of the inflamed tissue and a satisfactory surgical outcome.
BackgroundThis study compares endoscopic and microscopic tympanoplasty for the treatment of chronic otitis media (COM) without cholesteatoma.MethodsThis retrospective study included 153 ears (139 patients) treated surgically (endoscopic or microscopic tympanoplasty) for COM in the absence of cholesteatoma at our hospital between January 2008 and October 2015. The adoption of transcanal endoscopic ear surgery (TEES) or microscopic ear surgery (MES) was divided temporally (before and since 2014). Comparisons between these groups focused on the following: (I) surgical outcomes, including successful tympanic membrane healing and post-operative complications; (II) restoration of hearing; and (III) consumption of medical resources, including the duration of surgery and anesthesia. All patients had a follow-up period of at least 3 months after surgery.ResultsNo statistically significant differences were observed between the two groups regarding surgical outcome or hearing restoration. TEES resulted in the successful healing of 96.2% of ear drums, whereas MES led to successful healing in 92% (p = 0.2826) of cases. The average hearing gains following surgery were 10.27 ± 6.4 and 12.43 ± 7.46 dB in TEES and MES, respectively. The consumption of medical resources in the TEES group was lower than that of the MES group (TEES versus MES) regarding the average operating time (87.8 ± 19.01 min (mins) versus 110.2 ± 17.0 (mins) (p < 0.0001)) and the mean duration of anesthesia ((for general anesthesia patients) (122.1 ± 21.25 mins versus 145.8 ± 16.88 mins) (p ≤ 0.0001)).ConclusionsThe results indicate that TEES can achieve surgical outcomes and hearing restoration comparable to those of MES. In addition, TEES appears to be associated with shorter surgical and anesthesia time, which makes it an ideal alternative for the management of COM without cholesteatoma.Trial registrationThis study was approved by the Institutional Review Board of the Cathay General Hospital.

Objective: To analyze the long-term safety of mastoid obliteration with cartilage in children with suppurative cholesteatomatous ears. Methods: The medical records of children (≤18 years) with cholesteatomas after primary tympanomastoidectomies were performed with cartilage obliteration over a 30-year period (1982-2012) were analyzed. The recidivism rate was calculated using the Kaplan-Meier survival analysis. Potentially confounding factors of recidivism were entered into a Cox regression model as covariates for multivariate analysis. Results: Of the 150 cholesteatomatous ears in 146 children, there were 95 discharging ears (63%) in 94 children. Among the 95 discharging ears, tympanomastoidectomy was performed with cartilage obliteration (CO group) in 77 ears (81%) and without cartilage obliteration (WO group) in 18 ears (19%). The mean follow-up period was 12 years. Recidivism was observed in 16 ears in the CO group and 4 ears in the WO group. The 10-year cumulative recidivism rates were comparable between the CO and WO groups (19 vs. 25%, p = 0.762). Multivariate analysis confirmed that mastoid obliteration was not a negative predictor of recidivism (p = 0.760). Recidivism of cholesteatoma was detected within 6.5 years after surgery in the WO group and was found as late as 16.1 years after surgery in the CO group. Cartilage could be maintained in the cavity with limited resorption, preventing reretraction pockets and subsequent recidivism. Conclusion: This study provides evidence supporting the long-term safety, feasibility and effectiveness of mastoid cartilage obliteration for children with suppurative cholesteatomatous ears. Despite comparable recidivism rates between the groups, the potential for the delayed detection of recidivism with cavity obliteration may warrant long-term follow-up, with careful attention paid to the potential for recidivism during postoperative care in children. i 2014 S.
