Management Of Middle Ear Cholesteatoma Research Articles

Surgical management of middle ear cholesteatoma in children with Turner syndrome: a multicenter experience.

Background and aim: As in other syndromes characterized by craniofacial anomalies, middle ear cholesteatoma is known to have a high prevalence in Turner syndrome. The aim of this study was to review a multicenter experience with the surgical management of middle ear cholesteatoma in children with Turner syndrome. Methods: We retrospectively analyzed sixteen girls with Turner syndrome who underwent otologic surgery for middle ear cholesteatoma between January 2000 and December 2012. Surgery was performed in 3 tertiary care otologic centers. Four patients had bilateral disease, resulting in a total of 20 ears treated. The following data were recorded: age, history of ventilation tube insertion, status of the controlateral ear, cholesteatoma location and extension, and surgical technique involved. Cholesteatoma recidivism, stable mastoid cavity and hearing levels were the main outcomes measured. Results: Follow-up ranged from 3 to 15 years (mean 7 years). Fourteen ears underwent canal wall down mastoidectomy: no cases of recurrent cholesteatoma were observed in these cases; revision mastoidectomy with cavity obliteration was needed in 2 ears (14.3%) for recurrent otorrhea. In the remaining 6 ears a staged canal wall up mastoidectomy was performed: 1 child showed a recurrent cholesteatoma and required conversion to canal wall down mastoidectomy. A postoperative air-bone gap result of 0 to 20 dB was achieved in 6 ears (30%); in 9 ears (45%) postoperative air-bone gap was between 21 and 30 dB, while in 5 (25%) was >30 dB. Bone conduction thresholds remained unaffected in all cases. Conclusions: Cholesteatoma in children with Turner syndrome is a challenging entity for the otologic surgeon. Although not mandatory, canal wall down mastoidectomy should be regarded as the technique of choice to achieve a safe and dry ear in TS children with middle ear cholesteatoma. Intact canal wall mastoidectomy should be adopted only in appropriately selected patients such as those with limited attic cholesteatoma that can be regularly followed-up. (www.actabiomedica.it)

Cholesteatoma Definition and Classification: A Literature Review.

Cholesteatoma is a serious otolaryngologic condition that to date remains an important problem and poses a challenge to otolaryngologists around the world. To improve the approach pertaining to the diagnosis and management of middle ear cholesteatoma, clear, clinically applicable, and useful definition and classification of cholesteatoma are required. This review aimed to evaluate the current and most accepted descriptions and opinions concerning cholesteatoma. A review of the literature concerning different definitions and classifications of cholesteatoma was used in the preparation of the Cholesteatoma Guidelines, a project implemented by the European Academy of Otology - Neuro-otology.

Does Checking the Placement of Ossicular Prostheses via the Posterior Tympanotomy Improve Hearing Results After Cholesteatoma Surgery?

Posterior tympanotomy (PT) is often performed during the surgical management of middle ear cholesteatoma with extension in the retrotympanum area. This PT can also be used to control the right position of the ossicular prosthesis masked by the tympanic membrane reconstruction. To compare audiologic results after ossiculoplasty performed via the outer ear canal and via the PT for patients with cholesteatoma. Retrospective chart reviews were performed for 68 patients (68 ears) with cholesteatoma who underwent titanium ossicular prosthesis surgery between January 2007 and January 2011. We compared audiologic results between two groups: the WPT group (the group without checking the prosthesis via the PT) and the PT group (the group with placing and/or checking the prosthesis via the PT). A postoperative pure-tone average air-bone gap of 20 dB or less was considered a successful hearing result. Of the patients who underwent canal wall-up mastoidectomy for cholesteatoma with ossicular chain reconstruction by titanium prosthesis, 36 patients (20 total ossicular replacement prosthesis [TORP], 16 partial ossicular replacement prosthesis [PORP]) were in the PT group and 32 patients (16 TORP, 16 PORP) were in the WPT group. The global success rate (defined as a mean residual air-bone gap < 20 dB) was 50% in the WPT group (56% in the subgroup PORP, 44% in the subgroup TORP) and 42% in the PT group (62% in PORP, 25% in TORP). There was no case with extrusion of the prosthesis in either group. No facial palsy occurred during the postoperative period for either group. Control of ossicular prosthesis positioning via the PT does not improve hearing results after ossicular chain reconstruction in cholesteatoma surgery. However, this approach can be used during a second-stage procedure that avoids incisions within the external ear canal.

The value of otoendoscopy in the management of middle ear cholesteatoma.

Background:The surgical management of cholesteatoma is a controversial issue, particularly regarding intact-canal-wall mastoidectomy (ICWM) versus canal-wall-down mastoidectomy (CWDM). The current experiment compared the quality of visualization in different middle ear structures using ICWM with otoendoscopy with findings of CWDM by microscopy.Materials and Methods:The patients diagnosed with cholesteatoma underwent tympanomastoidectomy, and then the patients selected for CWDM were included in the study (25 patients: 11 females and 14 males). After removing the cholesteatoma from the involved areas, otoendoscopic examination was done with a 4 mm, 0° endoscope by a neurootologist. All five middle ear structures (lateral epitympanum, sinus tympani, posterior crus of the stapes, round window niche, and Eustachian tube orifice) suspected of occult cholesteatoma were evaluated in terms of having or lacking the pathology. Then, CWDM was performed and all of the mentioned sites were reevaluated for diagnosing occult cholesteatoma.Results:The symmetric measures were 73%, 92%, 63%, 81%, and 100% for lateral epitympanum, sinus tympani, posterior crus of the stapes, round window niche, and Eustachian tube orifice, respectively.Conclusion:Otoendoscopy was confirmed to have a great potential to be adopted by surgeons as a less invasive procedure in the surgical management of middle ear cholesteatoma.

Surgical management of middle ear cholesteatoma and reconstruction at the same time

Introduction. The surgical management of cholesteatoma. You can opt for a closed technique (mastoidectomy simple) or open surgery (radical mastoidectomy). The open mastoidectomy with reconstruction of the posterior wall of the middle ear reconstruction in one surgery combines the advantages of both techniques as adequate surgical exposure, eradication of cholesteatoma and anatomical reconstruction of the middle ear structures. Objective. To evaluate the surgical results in the management of cholesteatoma with the technique of open mastoidectomy with reconstruction of the posterior wall and the middle ear in one surgery. Methods. Prospective analytical observational study conducted between 2009-2012 with patients undergoing this surgical technique in the Hospital Universitario del Valle, performing preoperative clinical monitoring and quarterly postoperative tomography and previous assessments of hearing and pre -and postoperative audiometry. Results. 45 patients were studied. Mean Postoperative follow-up was 28 months. Surgical success was achieved in 93.3% of patients as measured by clinical and radiological follow. Hearing preservation was found after reconstruction of the hearing mechanism, based on measured audiometry auditory tone average (PTA) by the statistical test for paired samples between preoperative and postoperative PTA. (95% CI -1.47 to 12.15). Residual cholesteatoma was presented in 6.6%, three to four times lower than that reported in the literature. Conclusions. This type of surgery can be considered a successful technique in the treatment of cholesteatoma in selected cases.

Acquired middle ear cholesteatoma in children with cleft palate: Experience from 18 surgical cases

ObjectivesTo review an institutional experience with the surgical management of middle ear cholesteatoma in children with cleft palate. Materials and methodsWe analyzed retrospectively 18 children diagnosed with cleft palate who underwent surgery for acquired middle ear cholesteatoma between 2000 and 2007. The following data were recorded: age, sex, history of ventilation tube insertion, status of the contralateral ear, cholesteatoma location and extension, and surgical technique involved. Cholesteatoma recidivism, stable mastoid cavity and hearing levels were the main outcomes measured. ResultsFollow-up ranged from 5 to 12 years (mean 8 years). Twelve children underwent planned staged canal wall up mastoidectomy: a residual cholesteatoma was found and removed during the second-look procedure in 2 ears (16.6%); two children (16.6%) showed a recurrent cholesteatoma and required conversion to canal wall down mastoidectomy. A modified Bondy technique was chosen in two children with an epitympanic cholesteatoma with an intact tympano-ossicular system, while in the remaining four subjects a canal wall down mastoidectomy was performed because of an irreparable erosion of the postero-superior canal wall: no cases of recurrent cholesteatoma were observed in these 6 children; revision mastoidectomy was needed in one patient for cavity granulation. A postoperative air-bone gap result of 0–20dB was achieved in 11 children (61.1%); in 5 cases (27.7%) postoperative air-bone gap was between 21 and 30dB, while in 2 (11.1%) was >30dB. Bone conduction thresholds remained unaffected in all cases. ConclusionsOur results indicate that most cleft palate children with cholesteatoma can be managed with a canal wall up mastoidectomy with low complication rates. In extensive disease with large erosion of the canal wall as well in presence of a retraction pocket in the contralateral ear, a canal wall down mastoidectomy should be considered. In epitympanic cholesteatomas with an intact tympano-ossicular system and mesotympanum free of disease, the modified Bondy procedure is an effective surgical option. As in the general pediatric population, improvement or preservation of hearing can be obtained in most patients.

Endoscopic open technique in patients with middle ear cholesteatoma

The objective of this study was to describe an endoscopic open "centrifugal" technique used to treat middle ear cholesteatoma with antral and periantral extension, using a retrospective chart and video review of a case series performed in a university tertiary referral center. Charts and videos of patients who underwent middle ear endoscopic surgery from January 2007 to September 2009 were reviewed. Patients who were treated with endoscopic "centrifuge" open techniques were included in the study. Surgical indications were collected and the surgical technique described. The final study group consisted of 12/150 subjects (9 males and 3 females with a mean age of 40 years). All 12 patients who underwent endoscopic open tympanoplasty had antral, periantral or mastoid involvement of cholesteatoma with or without posterior canal wall erosion. They had sclerotic mastoids with the presence of the antrum and, in some cases, small periantral mastoid cells. In 9/12 patients, external auditory canal reconstruction was performed with a cartilage graft. In 3/12 patients, canal reconstruction was not performed. No subjects required a meatoplasty of the external auditory canal. Endoscopic "centrifugal" open techniques can be an option in the surgical management of middle ear cholesteatoma involving antral and periantral mastoid cells, in the case of sclerotic mastoids. Further study will be necessary to examine the long-term consequences of the endoscopic "centrifugal" open technique. 2C.

Transcanal atticoaditotomy and transcortical mastoidectomy for cholesteatoma: the Farrior-Olaizola technique revisited.

Conservative mastoid surgery in the management of middle ear cholesteatoma has been a subject of controversy for decades. Proponents of the combined-approach tympanoplasty for cholesteatoma do not entirely support the conservative approach in children, especially in the hands of an inexperienced surgeon. We describe here our experience with a modified technique of conservative mastoid surgery involving an atticoaditotomy and a separate simple mastoidectomy with lateral attic wall reconstruction (modified Farrior technique) that can be relatively safely used in the majority of cases of chronic squamous otitis media, even in children. This was a prospective analysis of the therapeutic effects and benefits of the technique used in 103 cases of cholesteatoma at Staffordshire General Hospital from 1991 to 1997. The follow-up was between 3 and 9 years. The study group consisted of 55 male patients and 48 female patients, including 28 children less than 16 years of age. The age ranges were 9 to 61 years in male patients and 10 to 48 years in female patients. After an audiological assessment, all patients underwent the described mastoid procedure, and some of them required revision surgery, mostly for a second look or for ossiculoplasty. The chief outcome measures used were complete eradication of disease, incidence of disease recurrence, and restoration of hearing. The steps of the procedure, its pros and cons, and the results of the series are presented. Also discussed is an overview of the literature pertaining to intact-canal wall mastoid surgery. Of the 103 patients, only 3 had a recurrence of disease, and 9 patients showed no hearing improvement. We conclude that this modified technique has several advantages over the previously described mastoidectomy procedures. It is a relatively simple and effective technique that can be performed even in children.
