Endoscopic transcanal transtympanic myringoplasty (ETTM) is a relatively easier technique than endoscopic transcanal tympanoplasty (ETT) for repairing tympanic membrane perforations. No studies have compared the outcomes of these two procedures with tragal perichondrium after 1-year. Furthermore, there is no evidence-based stratification according to variations in perforation size in endoscopic ear surgery. Therefore, we compared the 1-year outcomes of ETTM and ETT stratified according to perforation size. ⋯ ETTM is suitable for repairing small perforations, whereas ETT is preferred for large perforations. Both methods, and particularly ETTM, should be employed cautiously for medium perforations.

ENDOSCOPIC EAR SURGERY IN CROATIA - INITIAL RESULTS OF TOTAL ENDOSCOPIC TRANSCANAL MYRINGOPLASTY.
The aim of this study was to show clinical outcome in 56 patients with tympanic membrane perforation operated on by total endoscopic transcanal myringoplasty. Out of the total of 74 patients operated on exclusively endoscopically, we identified 56 patients in whom tympanoplasty type I (myringoplasty) was performed. In 43 patients (45 ears), myringoplasty was performed in a standard transcanal fashion with lifting of the tympanomeatal flap, and in 13 patient butterfly myringoplasty was performed. ⋯ No major complications were recorded. Our results of graft success rate and hearing outcomes are comparable with those of microscopic myringoplasties but without the need for external incisions and with reduced surgical morbidity. Hence, we recommend total endoscopic transcanal myringoplasty as the method of choice for tympanic membrane perforation regardless of its size and location.

Myringoplasty is a surgical procedure to reconstruct tympanic perforation. However, repair of anterior perforations is still challenging. To analyze the anatomical and hearing outcomes of myringoplasty with a new technique of chondroperichondrial graft via endoscopy, 23 adult patients were retrospectively analyzed. ⋯ The mean ABG improvement in our cohort was 9.83 ± 5.00 dB. The functional graft success rate was 95.65% (22/23). The convenience, reliability, time, and labor savings accrued from the approach described here make it a good choice for repair of anterior perforation of tympanic membrane.

ReviewIntratympanic corticosteroids for sudden sensorineural hearing loss.
Idiopathic sudden sensorineural hearing loss (ISSNHL) is common, and defined as a sudden decrease in sensorineural hearing sensitivity of unknown aetiology. Systemic corticosteroids are widely used, however their value remains unclear. Intratympanic injections of corticosteroids have become increasingly common in the treatment of ISSNHL. ⋯ Most of the evidence in this review is low- or very low-certainty, therefore it is likely that further studies may change our conclusions. For primary therapy, intratympanic corticosteroids may have little or no effect compared with systemic corticosteroids. There may be a slight benefit from combined treatment when compared with systemic treatment alone, but the evidence is uncertain. For secondary therapy, there is low-certainty evidence that intratympanic corticosteroids, when compared to no treatment or placebo, may result in a much higher proportion of participants whose hearing is improved, but may only have a small effect on the change in hearing threshold. It is very uncertain whether there is additional benefit from combined treatment over systemic steroids alone. Although adverse effects were poorly reported, the different risk profiles of intratympanic treatment (including tympanic membrane perforation, pain and dizziness/vertigo) and systemic treatment (for example, blood glucose problems) should be considered when selecting appropriate treatment.

Correlation of blast-induced tympanic membrane perforation with peripheral cochlear synaptopathy.
The auditory organs, including the tympanic membrane, cochlea, and central auditory pathway, are the most fragile components of the human body when exposed to blast overpressure. Tympanic membrane perforation (TMP) is the most frequent symptom in blast-exposed patients. The impact of TMP on the inner ear and central auditory system, however, is not fully understood. ⋯ A decrease in the number of excitatory central synapses labeled by VGLUT-1 in the cochlear nucleus was observed, however, regardless of the absence or presence of TMP. Our findings suggest that blast-induced TMP mitigates peripheral cochlear synaptic disruption but leaves the central auditory synapses unaffected, indicating that central synaptic disruption is independent of TMP and peripheral cochlear synaptic disruption. Synaptic deterioration in the peripheral and central auditory systems can contribute to the promotion of blast-induced hearing impairment, including abnormal auditory perception.
