instruction: hello doctor I have a metal taste in the mouth hoarse voice and scratchy throat I am not on any medicines or vitamin supplements I have not changed my diet in any way and my dental hygiene is very good I am allergic to aspirin and have no health issues at all I also have two inner ear conditions both are somewhat rare in the right semicircular canal dehiscence and in the left patulous eustachian tube dysfunction what I want to know is whether I can fly take an airplane without getting ill and sustain further inner ear damage
output: hello though the history you have given is insufficient to come to any conclusion about the possible causes I will give information about the common conditions which can have such symptoms the most common cause for scratchy throat with hoarse voice is routine throat infections such as acute pharyngotonsillitis or acute laryngitis which usually resolves with simple antibiotics and mouth gargles the next common cause which can present similarly is reflux laryngopharyngitis which is a type of acidity related disorder in this condition constant reflux of digestive acid into the throat causes injury to taste buds vocal cords and throat which leads to symptoms such as change of voice and change in taste in general people with reflux laryngopharyngitis will have symptoms such as burning sensation in chest repeated burping chest tightness dryness of throat etc regarding your inner ear conditions super semicircular canal dehiscence is a rare inner ear condition in this condition there will be giddiness and imbalance when exposed to loud noise and echoing of once own voice etc this condition usually does not get worsened by the change in environmental pressure so air travel would not be an issue in this condition in any case keep anti vertigo medications such as stemetil handy when you fly patulous eustachian tube is a condition involving the middle ear and nose my guess is because of the similarity in symptoms you have given in both the diagnoses I can say that if there is vertigo then it is superior canal dehiscence if there is no vertigo chances of patulous eustachian tube are high in any case people with patulous eustachian tube will have a certain degree of pressure symptoms in ear when they fly but most of the time it would not be very severe you can use simple saline nasal spray before boarding the flight and every two hours in the air to reduce symptoms
