Thanks for writing to H.C.M. for your query regarding sinus problem and thining and loss of hairs.
I would like to clear you that sinusitis
is not related with hair problem. For your hair problems you can consult skin specialist.
Your sinus disease is demanding investigations and detaled examination of nose and paranasal sinuses
to find out the extent of disease and is there any nasal septal defect or associated inferir turbinate hypertrophy. If any of these found that should be corrected along with sinus surgery
to get exillent result.
