Material and Methods: Tissue sections were stained by the following stains to demonstrate different mucins: H&E, Periodic acid-Schiff's (PAS), PAS-D, PAS-Ph AB ph 2.5 and 1, AF, combined AB-PAS, and combined AB 2.5–AF. Results: In group 1 - Sulphomucins and neutral mucins concentration is more compared to sialomucins. In group 2 - Increase in sailo mucins concentration compared to sulpho mucins and neutral mucin. In group 3 - increase in sailomucins. In adults -more acidic mucin especially sulpho mucin compared to sialo and neutral mucin and in sinonasal carcinoma- increase in sialo mucins compared to neutral and sulpho mucins. Conclusions: Change in functional collaboration of the cell before change in structure and hence affect the formation of mucins. Hence early detection of mucinal changes may be the first step before structural changes occurring in many diseases.
