Introduction: Subglottic cysts (SGCs) are a rare cause of laryngeal stenosis that mainly seem to affect preterm infants with an intubation history., Purpose: To review the related literature and compare different management protocols for patients presenting SGCs, as well as briefly report our clinical case treated at Verona University Hospital by Pediatric Airways Team., Methods: The articles resulting from a PubMed and MEDLINE search were analysed and selected using previously established criteria. A systematic review of the selected papers was conducted following PRISMA guidelines., Results: The search yielded 571 related articles; cross-checking of articles led to the identification and exclusion of 239 duplicates. The remaining 332 papers were screened according to previously established eligibility criteria. The final number of selected articles was 13., Conclusions: Well-planned teamwork, with active collaboration between the ENT specialists, pediatricians and anesthesiologists, is the key to achieve multidisciplinary management of patients diagnosed with SGCs. Long-term follow-up is crucial considering the high recurrence rate of this disease., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Objectives: The aim of the present study is to describe our experience in the management of tympanic cavity cholesteatoma in pediatric patients, treated with endoscopic exclusive transcanal approach., Methods: A chart review of clinical data and videos from the operations of 54 pediatric patients, undergoing surgery between January 2007 and December 2013, was made. Patients presenting with cholesteatoma involving the tympanic cavity (mesotympanum, epitympanum, protympanum and/or hypotympanum), with no mastoid involvement, were included in the first group and underwent an exclusive transcanalar endoscopic approach (TEA). In case of mastoid extension of the pathology, patients were included in the control group and underwent a canal wall up microscopic technique (CWU)., Results: In this study, 34 males and 20 females, including 5 bilateral cases, giving a total of 59 ears, were reviewed. Median age was 9.6 years (range 4-16 years). 31 cholesteatomas underwent a TEA approach, while 28 underwent a CWU approach, based on inclusion criteria. No differences from congenital vs acquired form was made, due to the difficult to correctly distinguish always the two forms. The ossicular chain was preserved in 26.6% of patients (16 ears): 42% of patients (13 ears) undergoing a transcanal endoscopic approach and 10% of patients undergoing a canal wall up microscopic approach (3 ears) (P=0.006). Second look surgery was executed in 41.6% of patients (25 ears). In partial ossicular prosthesis reconstructions, the mean preoperative pure-tone average was 29.4dB, while the mean postoperative pure-tone average was 27.1dB, with a mean increase of 2.3dB. In total ossicular prosthesis reconstructions, the mean preoperative pure-tone average was 47.8dB, while the mean postoperative pure-tone average was 26.5dB, with a mean increase of 21.3dB. Recurrence rate was 12.9% (4 ears) for the transcanal endoscopic approach group and 17.2% (5 ears) for the canal wall up microscopic approach. Residual disease was present in 26.6%: 19.3% (6 ears) for the transcanal endoscopic approach group and 34.4% (10 ears) for the canal wall up microscopic approach. The mean follow up was 36 months (range 8-88). Kaplan-Meier analysis at 36 months showed a lower recurrence risk for the transcanal endoscopic approach compared with the canal wall up microscopic approach, but this data was not statistically significant (P=0.58)., Conclusion: The transcanal endoscopic approach represents a feasible, minimally invasive and conservative technique for the management of pediatric middle ear cholesteatoma., (Copyright © 2014 Elsevier Ireland Ltd.
