Challenges and outcomes of cholesteatoma management in children with Down syndrome

Prevalence and surgical management of cholesteatoma in Down Syndrome children

OBJECTIVE

The objective was to report the outcomes of surgical management of cholesteatoma in Down Syndrome (DS) children and to determine the prevalence of cholesteatoma in DS children at three academic tertiary care centers.

METHODS

A retrospective chart review was performed of all DS children diagnosed with cholesteatoma from three tertiary care academic centers. Demographic data, comorbidities, imaging findings, surgical management, and pre- and postoperative pure tone averages were collected.

RESULTS

The prevalence of cholesteatoma in DS patients at these three institutions was calculated to be 8/802 (0.998%), 4/448 (0.893%), and 4/1016 (0.394%), with an average prevalence of 0.762%. Of the 16 patients with cholesteatoma identified, the average age of diagnosis was 10.8 years, and 5/16 (31%) had at least three sets of pressure equalizing tubes (PETs) placed. Of the 13 patients with preoperative CTs, 4/13 (30.8%) had blunting of the scutum, 4/13 (30.8%) had tegmen involvement, 1/13 (7.7%) had erosion of the semicircular canal, 2/13 had facial nerve dehiscence, and 7/13 (53.8%) had ossicular chain erosion. For surgical management, disease control was attained in 4/16 children with tympanoplasty only and canal wall up (CWU) tympanomastoidectomy in 11/16 patients. Available pre- and postoperative audiograms were evaluated; however, there was insufficient audiological data to contribute to outcomes.

CONCLUSION

Cholesteatoma occurs in nearly 1% of DS patients, and the disease tends to be advanced with tegmen involvement in nearly a third of patients, and ossicular erosion seen in more than half the patients. A CWU procedure can be successful in managing DS patients with cholesteatoma when consistent long term follow-up is planned. Close monitoring and a high index of suspicion for cholesteatoma are essential to prevent delays in diagnosis and treatment of DS patients with a history of multiple sets of PET placement.

Otolaryngologic Disease in Down syndrome

As the most common human chromosomal abnormality, Trisomy 21 is a condition that many otolaryngologists and likely all pediatric otolaryngologists will encounter during their careers. There are several considerations regarding airway obstruction, otologic conditions, anesthetic implications, and endocrine disorders that will impact the treatment of these patients. Further, there is increasing literature supporting the use of early instrumental assessment of swallowing, drug-induced sleep endoscopy at the time of first surgical intervention for sleep apnea, consideration of concurrent upper and lower airway evaluation, and early otologic management including potential surgical hearing rehabilitation.

Management of acquired cholesteatoma in patients with craniofacial anomalies: An institutional experience

PURPOSE

To analyze the surgical management of cholesteatoma in patients with craniofacial abnormalities, cleft lip/palate by reviewing the institutional experience. The secondary aim was to identify and describe the epidemiological profile of the collected data, and to relate the cleft palate and cholesteatoma.

DESIGN AND METHODS

This retrospective chart review includes 97 patients with craniofacial abnormalities and acquired cholesteatoma with anatomopathological proven in 118 ears. The following data were collected from the medical records between 1994 and 2018.

RESULTS

The first surgery performed on 76 of the 118 ears (64.4%) was the wall up mastoidectomy, while 42 of the 118 ears (35.5%) received the wall down technique. During the follow-up period of these patients, which ranged from 2 to 29 years, with an average of 13.4 years (±5.88), 77 wall up (40.3%) and 114 wall down (59.6%) mastoidectomies were performed. This brought the total to 191 mastoidectomy surgeries in 118 ears of 97 patients. Of the wall up mastoidectomies, 65 of the 77 (84.4%) presented with cholesteatoma recurrence. In the wall down mastoidectomies follow up, there were new surgical approaches in 15 of the 114 procedures (13.1%), with 6 patients (5.2%) having anatomopathologically proven cholesteatoma recurrences and 9 (7.8%) having clinical instability for cavity cleaning without identification of disease recurrence.

CONCLUSIONS

Early approach with wall down/modified techniques guided by specific indication criteria may be more resolute, prevent multiple procedures, and preserve the bone pathway to facilitate possible future hearing rehabilitation in these patients.

Endoscopic ear surgery in children with down syndrome

INTRODUCTION

Children with Down syndrome (DS) have a high incidence of chronic middle ear disease. Surgery to manage this disease is challenging due to the severity of illness and narrow ear canal dimensions. Endoscopic ear surgery is used to manage tympanic membrane and middle ear disease with the advantages of improved visualization and avoidance of post-auricular incisions. However, its application in children with DS has not been reported. We aim to compare the outcomes of endoscopic versus microscopic ear surgery in children with DS.

METHODS

All patients with DS who underwent tympanoplasty without mastoidectomy between 2012 and 2018 were identified, and their charts retrospectively reviewed. Rate of residual perforation, hearing, surgical time, and surgical details were recorded.

RESULTS

37 surgeries in 26 patients were identified that met inclusion criteria. Two subgroups were analyzed. The first included 14 cases that were done using traditional microscopic visualization (MV). The second included 17 cases that had substantial or exclusive use of endoscopic visualization (EES). Due to a learning curve, the number of cases done endoscopically increased over time. The average age in MV was 13.9 years vs 11.0 in EES. The MV cases included 2 with cholesteatoma vs 4 in EES. In cases with adequate follow up, residual perforations were found in 1/13 MV, and 4/17 EES. All of the residual perforation cases in EES used acellular porcine submucosa grafts. None of the cases in MV used this material. Average air bone gap reduction was seen in both groups; 4.2 dB in MV, 9.8 dB in EES. Average surgical time was similar between groups; 124 min in MV, 115 min in EES. All cases in MV required a post-auricular incision and approach to the middle ear. Only four cases in EES required this approach. Six cases in EES did not require any incision outside of the ear canal for either graft harvest or middle ear approach.

CONCLUSION

Endoscopic and microscopic ear surgery in children with DS have similar outcomes. There were no statistical differences in hearing results, surgical times, or residual tympanic membrane perforations, although the rate of perforations in the endoscopic group trended higher. Most endoscopic cases did not require conversion to a post-auricular approach. Endoscopic surgery allows some DS patients to avoid any incision outside of the ear canal.
