Hi all... I am a diver based in from UK, based in Bali. I come home once a year. I have had chronic problems with equalizing my upper left frontal sinus for years now. I am researching to find out if anyone knows of the best ENT Dr (Ear/Nose/Throat) specialist. I am looking into some form of surgery, perhaps "balloon sinuplasty". Please keep in mind that I have tried everything else and this is my last resort. I simply want to know about anyone who has had sinus surgery and where/who did it for them? Are there any specialist Doctors in the UK who understand diving sinus issues? Thanks.
