Mucormycosis is caused by fungi of the order Mucorales and is one of the most rapidly fatal fungal infections known to man. Rhinocerebral mucormycosis is the most common type and its extension to the orbit and brain is quite usual. Location of mucormycosis on the palate is a rare and late occurrence. A case of deep hard palate ulcer due to sinonasal mucormycosis in a 79-year-old man is reported. He was successfully treated with a combination of surgical debridement and systemic liposomal amphotericin B administration for six weeks. By presenting this case report we would like to point out that mucormycosis should be included in the differential diagnosis of hard palate ulcers.

Transtympanic iontophoresis could be an effective method for the passage of pharmaceutical agents into the middle and inner ear for the treatment of middle and inner ear diseases.

With the solution of water and gadopentetate dimeglumine, the maximum SSNR and CSNR with both SE and GRE MR imaging sequences were achieved. The solution can be transferred to the middle and inner ear cavities across an intact tympanic membrane by using transtympanic iontophoresis.
