Thanks for using Health Care Magic Forum,
Your son is most likely to suffer from Atrophic Rhinitis
in which the nasal cavities become roomy and are filled with foul smelling crusts which are black or dark green and dry, making expiration painful and difficult.
Microorganisms are known to multiply and produce a foul smell from the nose, though your son may not be aware of this, because their elements (responsible for the perception of smell) have become atrophied.
Your Son usually complain of nasal obstruction
despite the roomy nasal cavity
, which can be caused either by the obstruction produced by the discharge in the nose, or as a result of sensory loss due to atrophy
of nerves in the nose
Bleeding from the nose, may occur when the dried discharge (crusts) are removed.
One of the most widely used treatments is NASAL IRRIGATION
1) Irrigations are used to prevent the formation of the hallmark extensive crusting. To achieve this result, irrigations must often be done multiple times in a daY
2) 25% glucose
in glycerine can be applied to the nasal mucosa to inhibit the growth of foul-smelling proteolytic organisms.
