“…Emmett and Shea 15 reported that diatrizoate meglumine enhanced complete return of hearing (38%) and partial return (50%) in sudden hearing loss. Torihara et al 6 thought that contrast media affected the stria vascularis parallel with osmolality. The contrast media are osmotic ionic agents.…”

The radiopaque contrast medium diatrizoate, has a vasodilator effect so that it is used in sudden-deafness secondary ischemic injury. However, ischemic problems are encountered, especially when longer flaps are elevated. A longer flap also has ischemic and relatively ischemic tissue, and may obtain some benefit from contrast media. Forty male Sprague-Dawley rats, weighing about 350-400 g, were used, and randomly divided into four groups (n = 10 rats each group): group 1 was the control, group 2 the diatrizoate, group 3 the iopamidol, and group 4 the iothalamate group. A rectangular 3 x 10 cm caudally based dorsal skin flap was elevated, and sutured back to its original place. In the control group, no pharmacologic agent was administered. Sodium-meglumine-diatrizoate 10 mg/kg/day was administered parenterally in the first experimental group (diatrizoate group); iopamidol 10 mg/kg/day in the second experimental group (iopamidol group); and iothalamate sodium 10 mg/kg/day in the third experimental group (iothalamate group) for 7 postoperative days. On postoperative day 7, all flaps were photographed, and the area of flap survival was measured by using a polar planimeter. The results were statistically evaluated with the Kruskal-Wallis test and Mann-Whitney U-test (P = 0.05). The mean flap survival ranged from 79% in the iopamidol group to 83% in the diatrizoate group, and was significantly greater in all experimental groups (P < 0.05) compared to the control group (59%). There was no significant difference between experimental groups (P < 0.05). We believe that radiopaque contrast media have a beneficial effect in improving skin flap viability when distal flap necrosis is a potential complication of longer flaps.

“…4 A limited number of studies have examined the relationship between contrast agent and hearing impairment. [5][6][7][8] Therefore, due to the high prevalence of injection of contrast agent in the clinic and also develop strategies to prevent undesired side effects of contrast agent injection, the present study was carried out to investigate the effect of contrast agent on SNHL in patients undergoing angiography of coronary artery disease in Valiasr Hospital of Birjand city of Iran.…”

Objective: This study was conducted to investigate the effect of contrast agent used in angiography on sensorineural hearing loss. Methodology: This Quasi experimental study was conducted at Valiasr hospital, Birjand, Iran on 157 coronary artery disease patients hospitalized for angiography. The hearing level of the right and left ears was measured individually before and after the angiography. Then, to calculate the mean auditory threshold of the patients, the hearing level was averaged at three different frequencies of 500, 1000, and 2000 Hz. After data collection and introducing them into SPSS 22, descriptive statistics (frequency percentage distribution, mean and standard deviation) were used along with Mann-Whitney and Kruskal-Wallis tests at the significance level of 0.05. Results: Out of the 157 patients studied, 79 (50.3%) were male. The mean age of the subjects was 57.62±10.17 years (29-85 years), which was 57.67±9.31 in women and 56.85±11 in men. The hearing level of the right ear before and after injection of the radiocontrast agent was 23.69±13.18 and 23.33±13.30 db, respectively, while in the left ear, the values were 25.14±15.01 and 25.02±15.16, respectively, where this difference was not significant (p>0.05). Conclusion: There is no appreciable effect of radiocontrast agent on neurosensory auditory disorder of patients undergoing angiography of coronary artery disease Keywords: Contrast agent, hearing loss, Angiography.
