Otitis media with effusion (OME) is the most common cause of hearing loss in children and ventilation tubes (VT) is accepted as a standard surgical treatment, which is the most common operation in young children requiring multiple general anesthesia (GA). Laser myringotomy (LM) was introduced as an option for office-based ventilation under topical anaesthesia (TA) to avoid the concerns of families who refuse VT and GA. The efficacy of LM without VT was reported to be 40% resulting in frequent failures, which is roughly between that of knife myringotomy (KM) and VT insertion. LM-assisted VT insertion overcame the frequent LM failure and reduced GA, but the limited feasibility of LM-assisted VT in young children requires the integration of two procedures. In our clinic, these children have been allocated to ¡°flexible integration of laser tympanostomy and ventilation tube insertion under topical anaesthesia¡± (FITT) procedure. FITT is 1) To stop antibiotic overuse 2) To restore normal hearing promptly with VT insertion 3) To assess the outcome of VT: duration until extrusion, otorrhea and 4) To decide the need for long-term treatment such as adenoidectomy or long-term tube. We have reported that LM-assisted VT insertion was feasible in 73% for one VT, and 45% for both VT, which could reduce 80% of required GA. Tympanostomy tube otorrhea (TTO) may occur immediately after tube insertion from an existing infection in the middle ear or later, with subsequent middle-ear infections or infectious processes in the ear canal. Treatment of TTO has favored the topical therapy in the form of eardrops with or without systemic antibiotic therapy.
