Suggest Treatment For Otalgia

My wife 66, was having tinnitus in left ear since last few months. Later it subsided but occasional otalgia developed. At the same time, a problem in fixed denture on left lower premolar/molar put a confusing picture about the cause. However, denture removed but the otalgia remained as it is. Consulted an MS (ENT). who after PTA, Tympanometry & radiological exploration decided that it is probably due to some elongation in the left styloid process. Advised to take a) Choriminic tab morning/afternoon, Dompra in mornig empty stomach & Otrinoz in both nostrils in head tilted condition so that medicine moves through the eustachian tube . Situation improved a bit with occasional pain at a lesser degree. Is operation the only solution? How risky it is ?
