The results of this study suggest that adding intratympanic methylprednisolone to systemic therapy increases the probability of hearing recovery in ISSHL patients.
To evaluate the effect of septal pathology and surgery on nasal mucociliary clearance. A radioisotope method was used to measure the velocity of nasal mucociliary transport. Nasal mucociliary clearance was measured before and after septal surgery using technetium-99m macroaggregated albumin. Fifteen patients (mean age: 20 +/- 8 years; 11 males, four females) were studied pre-operatively, but scintigraphy could be repeated only in 10 patients, 2 months after surgery. A group of 10 healthy volunteers were also studied. The clearance values obtained from the preoperative period (26.25 +/- 9.45 min) were significantly higher than those of the post-operative period (15.05 +/- 6.35 min). The values obtained of control group (13.30 +/- 3.15 min) were not significantly different from the post-operative values of the patient group. Septal deviation affects the mucociliary activity. It is improved by surgery. This study showed that nasal septal deviation reduced the nasal mucociliary activity, and this can easily evaluated with scintigraphy.
We conclude that IT methylprednisolone injection provides more significant hearing improvement for patients that failed with previous high-dose systemic corticosteroid administration than systemic corticosteroid treatment alone. So it may be the first-step medical treatment of idiopathic SSHL alone or at least may be combined with the systemic corticosteroid administration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
