Endoscopic Middle Ear Cholesteatoma Surgery with Combined Alternating Continuous Irrigation and Non-Irrigating Modes

Objective The purpose of this paper is to determine optimal use of continuous irrigation in endoscopic ear surgery and establish a.surgical protocol with combined alternating continuous irrigation and non-irrigating mode for endoscopic resection of middle ear cholesteatoma.Methods Data from 73 patients(34 females and 39 males,aged 10-68 years)with unilateral upper/upper and middle tympanic middle ear cholesteatoma admitted between January 2019 and December 2020 were retrospectively analyzed.Combined alternating continuous irrigation/non-irrigating mode was used during endoscopic middle ear surgery in 33 patients,and conventional non-irrigating mode was used in 40 patients.All the operations were performed by the same surgeon.In the combined continuous irrigation/non-irrigating technique,continuous irrigation was used from skin incision,unless bleeding from medial wall of the tympanum affected vision,and throughout exposure,exploration,bone and lesion removal,while tympanoplasty including ossicular chain reconstruction and reconstruction of epitympanum wall were performed in a non-irrigating mode.Results There was no significant difference in average age,preoperative hearing levels and the scope and severity of lesions between the two groups.All eligible medical records were included in retrospective analysis,with no selection bias.The average operation time was 86.52±7.30 min in the 33 patients in whom combined continuous irrigation and non-irrigating modes were used,and 117.15±9.34 min in the 40 patients in whom the conventional non-irrigating mode was used.In one patient,the floating ear canal flap affected visualization under continuous irrigation and was removed together with the tympanic membrane to complete the surgery.The ear canal flap was kept in place in the 32 cases.Conclusion To a certain extent,continuous irrigation operation helps incision hemostasis during endoscopic ear surgery,and more importantly facilitates bone removal.When adequately planned and employed,continuous irrigation and non-irrigating mode can be combined and conveniently alternated when needed,which can greatly simplify the operation process and shorten operation time.The technique may be worth adopting in clinical practice.
