Study of Tympanoplasty in Vijaywada Population

33 males and 12 female patients were selected for tymponoplasty either righter left harvesting of the tragalcartilage graft with a thickness between 0.2 to 0.4 mm and techniques used were underlay techniques and lateral to the hand of malleus supported by gel foam on both sides. During the study mean value of diameters of external canal in 21 males (63.6%) was 1.2 mm, and 12 males (36.3%) it was 1-4mm. In females 7 females (58.3%) the diameters of external canal was 1.2mm and in 5 females (41.6%) it was 1.3mm. The size of perforating gap in tympanic membrane Air borne gap range and average range study. 20 males had 1-2 mm perforations, air borne range was 10-31 dB and average range was 22dB. In 10 males the perforation size was upto 1mm, air borne range was -0.25mm, the average range was 11dB.In 3 males air borne range 17-31dB and average range was 23 dB. In females study 7 females had 2-3mm perforation, air borne range was 14-36 and average was 24 dB, In 3 females perforation was upto 1mm, air borne range was 0-25 dB and average was 9 dB, In 2 females had 3-4mm perforation, air borne range was 17-31 dB and average range was 23 dB. This study of tympanoplasty by tragal cartilage will be certainly helpful to junior ENT surgeons and biotechnologist to invent such similar technique in future.
