Simple underlay myringoplasty is a simple and minimally invasive procedure employing fibrin glue and has led to a high closure rate of the eardrum.

The mean of the postoperative hearing gain was 10.3 dB and no cases of postoperative hearing loss were observed. Although postoperative re-perforation was found in 18 cases (24.0%), the re-perforation was closed in 16 of these cases in the outpatient department by the same procedure using frozen autologous tissue that had been harvested previously in surgery. Including these cases, the total success rate was 97.3%.

Confirmation of the conditions of the ossicles is essential for tympanoplasty. However, at present, ossicular mobility is experimentally estimated with palpation by a surgeon, and the results depend on the surgeon's skill. In this study, a new apparatus for quantitatively measuring ossicular mobility was developed. With this apparatus, the ossicles were displaced and the reaction force from the ossicles, (i.e. the load applied to the ossicles) was simultaneously detected. Ossicular mobility of three patients with otosclerosis or chronic otitis media was measured to evaluate the usability of the apparatus. The apparatus can distinguish the differences in ossicular mobility between normal and fixed ossicles, and it makes estimating the change of mobility between pre- and posttreatments for ossicular fixation possible. Positive correlation was seen between ossicular mobility and hearing level.

The postoperative configuration of the posterior meatal wall showed severe retraction in 7 of 8 patients with habitual sniffing, but only 22 of 47 without habitual sniffing. Habitual sniffing was significantly associated with postoperative severe retraction (Fisher's exact test, p<0.05).

Objectives/Hypothesis Congenital middle ear anomalies represent a relatively rare condition. This study aimed to describe the characteristics and the surgical outcomes for patients with middle ear anomalies. Methods A multicenter study was conducted of consecutive patients with congenital middle ear anomalies who underwent primary surgical treatment between January 2008 and December 2017. Demographics, surgical procedures, and audiometric data were registered into the institutional database. Hearing changes and postoperative air‐bone gap (ABG) were evaluated 1 year after surgery. Results A total of 246 patients (246 ears) (median age: 14 years, range: 4–75 years old) were included in this study. Anomalies were subdivided using the Teunissen and Cremers classification: 53 ears (22%) were categorized as class I, comprising only stapes ankylosis; 35 ears (14%) as class II, having ossicular chain anomalies with stapes ankylosis; 139 ears (57%) as class III, having ossicular chain anomalies with a mobile stapes‐footplate; and 19 ears (8%) as class IV, with aplasia of the oval window. Evaluation of hearing outcomes for 198 ears with more than 1 year of follow‐up revealed that good postoperative ABG (≤20 dB) was achieved in 82% of class I, 68% of class II, 74% of class III, and 23% of class IV anomalies. The postoperative ABG in class IV was significantly worse than in class I (P < .001) or class III (P < .01). Conclusions This study demonstrated that class III anomalies comprised the majority of middle ear anomalies and surgical outcomes for class IV anomalies are unfavorable.
