HI I have gone through your mail as you said you are interested in knowing about the eustachian tube dysfunction due to follicular pharyngitis leading to hearing loss and it s management. In this connection I would like to tell you that infective conditions of pharynx (may be associated with adenoiditis and tonsillitis )causes inflammatory swelling of pharyngeal opening of eustachian tube leading to blocking of tube thus transport of air to middle ear suffers which results negative pressure of air in middle ear which causes retraction of ear drum and decreases movements of ear drum and patient feels heard of hearing.To treat this first of all I would try to find out infective organism by culture and sensitivity of throat swab which also tells us about correct antibiotic to be chosen. Along with antibiotic we should also advice anti-inflammatory, antihitaminics and steam inhalation. By this conservative treatment usually patient gets improve but if this conservative treatment fails than we look for enlarge tonsils, adenoides and sinusitis .if any of these found that should be treated If still tube is not found patent than we put grommet in ear drum which will solve the problem. Thanks
