“…However, if a rigid unified scheme had been used, a higher volume would have unnecessarily been applied. Although 0.8 ml is among the lowest of the volumes reported in existing studies, [5][6][7][8][9][10] it was sufficient in our patient.…”

“…4 Most recently, the injection of autologous fat, cartilage or hydroxylapatite has been described for cases of Eustachian tube occlusion, with promising results. [5][6][7][8][9][10] This experimental procedure is relatively minimally invasive compared to other surgical methods. However, results vary among case studies and there is not always complete resolution of symptoms.…”

ObjectiveThere is currently no general consensus on patulous Eustachian tube management. Injection of autologous fat, cartilage or hydroxylapatite has been described for Eustachian tube occlusion, with promising results. However, complete resolution of symptoms is not achieved in all cases. This could be connected to the amount of material injected into the surroundings of the Eustachian tube, as this greatly differs among existing studies. Identifying the appropriate volume of injected material could be challenging because anatomical conditions vary among patients, and there is always a risk of chronic Eustachian tube obstruction and its related complications when too much long-standing material is injected.Case reportA case is presented wherein saline was injected under local anaesthesia to determine the volume required and to predict the success of patulous Eustachian tube augmentation with long-standing material.ConclusionThis approach could allow more personalised treatment and help identify patients likely to benefit from the procedure.

“…Injection material included: Teflon, silicone, cartilage, gelatin sponge, calcium hydroxylapatite, and a polytef paste (33)(34)(35)(36)(37)(38)(39)(40)(41)(42). The manufacturer of polytef paste has since advised against these injections because of a report of cerebral thrombosis and death resulting from injection into the internal carotid artery.…”

“…Bleeding from the septal graft harvest site and other technical challenges prompted the authors to switch to alloderm. Injection of Radiesse by Wolraich was confounded by patient comorbid conditions such as recent weight loss, previous surgeries, and botulinum toxin injection for palatal myoclonus (38).…”

“…It was successfully managed by the endoscopic transoral injection of calcium hydroxylapitite. 103 Another strategy for treating the symptoms of a patulous ET, without manipulating the ET, was a simple mass loading of the TM with Blu Tack, a claylike, nontoxic substance. This technique successfully improved the symptoms of 14 patients.…”

In the future, imaging technologies should be developed to noninvasively assess ME/ET structure and physiology with respect to their role in OM pathogenesis. The new data derived from form/function experiments should be integrated into the finite element models and used to develop specific hypotheses concerning OM pathogenesis and persistence. Finally, rigorous studies of treatments, medical or surgical, of ET dysfunction should be undertaken.
