3.2 Complications
After the patients received different treatments, we counted the
incidence of complications in ITD group and ITL group. As showed in
table 3, compared with the ITL group, the incidences of external
auditory meatus mycosis (p = 0.029) and tympanic membrane thinning (p =
0.018)were significantly higher in the ITD group which had been further
elaborated in section 3.3 and 3.4.In addition, two patients in the ITD
group had perforation accompanied by external auditory meatus mycosis,
and one of them had recovered from the perforation after active
treatment which had been elaborated in section 3.4. .No tympanic
membrane perforation was observed in the ITL group. There was no
statistical difference in the incidence of vertigo, pain, tongue
numbness, tinnitus and other complications between the two groups.
