Comparative study of endoscopic and microscopic tympanoplasty performed by a single experienced surgeon.

PURPOSE: The use of endoscopes in otologic procedures has been increasing worldwide. This study aimed to compare the efficacy of microscopic tympanoplasty (MT) and endoscopic tympanoplasty (ET) for tympanic membrane and middle ear surgery. MATERIALS AND METHODS: We retrospectively analyzed 81 patients who underwent MT (n = 44) and ET (n = 37) for chronic otitis media with tympanic membrane perforation performed by a single surgeon between January 2013 and September 2019. The hearing outcomes, graft success rate, complications, operation time and hospital stay, and cost-effectiveness were recorded and compared between groups. Hearing outcomes were determined by pure tone audiometry. Cost-effectiveness was determined by the operation cost and total cost. RESULTS: There was no significant difference between the MT and ET groups regarding demographic characteristics, with the exception of the male:female ratio. There was no significant difference in the pre- and postoperative air conduction, bone conduction thresholds, and air-bone gap values between the two groups, but a significant audiologic improvement was observed in both groups (p < 0.05). In terms of recurrence of tympanic membrane perforation, postoperative otorrhea, and discomfort symptoms, there was no significant difference between groups (p > 0.05). The operation time and hospital stay were shorter in the ET group than in the MT group (p < 0.05). There were no significant differences in operation cost between the two groups (p > 0.05), but the total cost was significantly lower in the ET group than the MT group (p < 0.05). CONCLUSION: ET is as safe and medically efficacious as conventional MT, shortens the operation time and hospital stay, and is cost-effective.

Comparison of the medical costs and effects of large traumatic eardrum perforations treatment.

OBJECTIVE: We investigated the medical costs and effects of ofloxacin drops (OFLX), gelatin sponge patches, spontaneous healing, and endoscopic myringoplasty on healing in large tympanic membrane perforations (TMPs). METHODS: In total, 100 patients with large traumatic TMPs involving >50% of the eardrum were randomly assigned to OFLX, gelatin sponge, spontaneous healing, or endoscopic myringoplasty treatment groups. Medical costs, closure times, and closure rates were compared among groups at 6 months. RESULTS: The closure rates in the OFLX, gelatin sponge, spontaneous healing, and endoscopic myringoplasty groups were 95.7%, 82.6%, 58.3%, and 91.7%, respectively (P = 0.05). The mean closure time was 13.73 ±â€¯6.14 days in the OFLX group, 15.89 ±â€¯4.95 days in the gelatin sponge group, 48.36 ±â€¯10.37 days in the spontaneous healing group, and 12 days in the endoscopic myringoplasty group (P < 0.001). The mean medical costs in US dollars were $15.53 ±â€¯3.15, $103.64 ±â€¯111.58, $11.17 ±â€¯1.33, and $715.90 in the OFLX, gelatin sponge, spontaneous healing, and endoscopic myringoplasty groups, respectively (P < 0.001). CONCLUSION: Although the gelatin sponge and myringoplasty treatments significantly shortened the closure time compared with spontaneous healing, the gelatin sponge patch did not significantly improve the closure rate, and the medical cost of myringoplasty was significantly higher than that of the other treatments. In contrast, OFLX significantly shortened closure time and had a higher closure rate than spontaneous healing, and the medical costs were lower than those of the gelatin sponge and myringoplasty procedures.

A willingness-to-pay assessment of parents' preference for shorter duration treatment of acute otitis media in children.

OBJECTIVE: To assess parental willingness to pay (WTP) for a shorter course of antibacterial treatment versus conventional antibacterial therapy for acute otitis media (AOM). METHODS: The study population consisted of 562 parents of children who had been seen and treated by a paediatrician for an episode of AOM between February and November 2002 in Montreal, Quebec, Canada. At the end of the AOM treatment, a questionnaire that included demographic information about the parents and child, details of the child's AOM history, a global wellbeing (i.e. quality of life) assessment, an evaluation of treatment compliance and a scripted WTP question was administered over the telephone. Descriptive analyses were performed in addition to a multivariate analysis to estimate possible predictors of parental WTP. RESULTS: The children with AOM were representative of the AOM patient population, with 46% being <2 years of age and the majority attending day-care or school. Parents were willing to pay a median of 31.66 Can dollars (2002 values) for a mono-dose (one dose, on 1 day) and 26.63 Can dollars for a tri-dose (one dose daily, for 3 days) antibacterial treatment. Regression analyses demonstrated that the amount parents were willing to pay was positively associated with increasing household income, increasing number of AOM episodes during the previous year and experiencing adverse effects of treatment. CONCLUSION: Parents of children with AOM were willing to pay more for their child to benefit from a shorter duration of antibacterial treatment than for a standard course. Short duration of treatment appears to be associated with better compliance and parents' perception of better general wellbeing for their child.
