Deafness in Children-Grommets (V tubes) - Dr.K.O.Paulose FRCS

Deafness is a partial or complete loss of hearing, also known as hearing impairment. The normal threshold range is 0-20 decibels (dB), where 0 dB is the threshold for the perception of sound at a given frequency for people with normal hearing.

There are 3 types of hearing loss:
Conductive hearing loss: affects 4% of all school children. Almost all cases are due to glue ear. Sensorineural hearing loss: affects 0.3% of all schoolchildren. Mixed hearing loss has components of both conductive and sensorineural hearing loss.

Myringotomy is a surgical procedure in which a tiny incision is created in the eardrum to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A Grommet tube is inserted into the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid. Without the insertion of a tube, the incision usually heals spontaneously in two to three weeks. Depending on the type, the tube is either naturally extruded in 6 to 12 months or removed during a minor procedure
