Primary Cartilage Tympanoplasty: Our Technique And Results.(dr Mubarak Khan,pune) Am J Otolaryngol. 2010 Sep 9. [epub Ahead Of Print]primary Cartilage Tympanoplasty: Our Technique And Results.khan Mm, Parab Sr.abstractcartilage Has Shown To Be A Promising Graft Material To Close Tympanic Membrane Perforations. However, Due To Its Rigid Quality, Doubts Are Raised Regarding Its Sound Conduction Properties. It Has Been Suggested That Acoustic Benefit May Be Obtained By Thinning The Cartilage. We Describe Our Innovative Method For Harvesting Tragal Cartilage From The Same Endaural Incision And Also Describe Preparation Of The Graft By Slicing It. We Present Our 3-year Experience Of Shield Cartilage Type 1 Tympanoplasty Using Sliced Tragal Cartilage-perichondrium Composite Graft.aim: The Aim Of This Study Was To Prove The Success Rate Of Our Technique Of Shield Cartilage Tympanoplasty Using Sliced Tragal Cartilage Graft In Terms Of Functional And Anatomic Results.study Design: Retrospective Analysis Of Type 1 Cartilage Tympanoplasties Using Sliced Tragal Cartilage Was Carried Out In Mimer Medical College And Sushrut Ent Hospital During May 2005 To January 2008 With A Minimum Follow-up Of 2 Years.method And Materials: A Total Of 223 Ears Were Operated By Our Technique.results: The Overall Success Rate Of Our Technique Was 98.20% In Terms Of Perforation Closure And Air Bone Gap Closure Within 7.06 ± 3.39 Db. The Success Rates In The Various Age Group Are As Follows: 11 To 20 Years, 97.67%; 21 To 40 Years, 99.12%; And 41 To 60 Years, 96.96%.conclusion: Our Technique Of Type 1 Cartilage Tympanoplasty Achieves Good Anatomic And Functional Results.

Color Blindness Is An Inherited Defect Of Vision, Resulting In A Person's Inability To Distinguish Between Specific Colors.partial Color Blindness Is More Common Than Total Color Blindness, In Which A Person Sees Everything As Shades Of Gray(grey). The Most Common Form Of Partialcolor Blindness Leads To Inability Todistinguish Between Red And Green And Rarely Between Blue And Yellow.color Blindness Is A Fairly Common Conditionwhich Occurs More In Men Than Women, But It Is Rarely A Serious Disadvantage To Those Affected.approximately One In 20 Men And One In 200 Women Are Affected .some Studies Suggest That About Eight Percent Of The World's Male Population And Less Than One Percent Of Female Population Are Affected .many People Are Unaware They Are Color Blind Until Their Eyes Have Been Tested .the Retina Compromises Two Types Of Photoreceptors , Rods And Cones. Although The Rods Are More Numerous, Some 120 Million, And Are More Sensitive Than The Cones, They Are Not How-ever, Sensitive To Color. Rods Are Responsible For Vision At Low Light Levels(scotopic Vision) And They Do Not Meditate Color Vision And Have A Low Spatial Acuity The Six Or Seven Million Cones That Provide The Eye's Color Sensitivity Are Much More Concentrated In The Central Yellow Spot Known As The Macula.being Active At Higher Light Levels (photopic Vision) Cones Are Capable Of Color Vision And Are Responsible For High Spatial Acuity. In Simple Terms It May Be Said That Cones Require Brighter Light To Function Than Rods.red ,green And Have Their Corresponding Wavelengths . Red Wavelengths Are Longest, Followed By Green Wavelengths (medium) And Blue Color Is Made Up Of Shorter Wavelengths .they Are Red , Blue And Green Cones Which Are Sensitive To Those Colors And Combinations Of Them. If The Cones Do Not Work Properly Or If There Is No Right Combination, The Brain Does Not Get The Right Message About The Colors You Are Seeing.the Visible Colors From Shortest To Longest Wavelength Are Violet, Blue , Green , Yellow , Orange And Red.the Visible Red Light Having A Wavelength Of About 650 Nanometers Is Responsible For The Presence Of Red Or Orange Color At Sunrise And Sunset, Because The Wavelengths Associated With These Colors Are Less Efficiently Scattered By The Atmosphere Than The Shorter Wavelength Colors Such As Blue Or Purple.the Visible Green Light Having A Wavelength Of About 510 Nm Makes The Grass Appear Green Because All The Colors In The Visible Part Of Spectrum Are Absorbed Into The Leaves Of The Grass Appears Greenthe Visible Blue Light Having A Wavelength Of About 475 Nm Are Scattered More Efficiently By The Molecules In The Atmosphere Which Cause The Sky To Appear Blue.people Who Are Born Blind Do Not See Images In Dreams, But Have Dreams Vivid Involving Their Other Senses Of Sound, Smell, Touch And Emotion.color Blindness Caused By A Disease Of The Retina Or Optic Nerve Is Progressive And Associated With A General Deterioration Of Vision, Unlike Inherited Variety Where The Ability To See Detail Is Unaffected And The Condition Never Worsen.it Is Tested With Ishihara Chart Normally Their Are Means Of Testing Colour Blindness.
