RESUMO
To compare surgical outcomes with different meatoplasty techniques without removal of a cartilage piece in canal wall down mastoidectomy. Total 61 patients of canal wall down mastoidectomy included in the study where either inferior based flap technique or division in middle technique meatoplasty performed and 2 groups formed. Group A consisted of 33 patients and the inferior based flap technique of meatoplasty used in these patients. Group B consisted of 28 patients and the division in middle technique of meatoplasty used in these patients. Granulations, discharge or stenosis of canal were observed in less than 8% of cases in both the groups. Meatoplasty done without incision or excision of a piece of cartilage from pinna can be achieved with good success rates with either inferiorly based flap technique or division in middle technique.
RESUMO
The purpose of the study is to investigate how Collagen sheet used as graft material in Myringoplasty improves hearing and tympanic membrane tissue repair in patients with tympanic membrane perforation (TMP) in an office based procedure. Total 50 cases included in the study where Collagen sheet used as graft material for myringoplasty in small to moderate size tympanic membrane perforations(TMP) and procedure performed in an office based set up with the help of a High definition endoscope and camera. Cases followed up regularly and results observed in terms of graft uptake and complete closure of TMP and hearing improvement. Out of 50, complete closure of TMP observed in 39 cases and an average hearing gain of 9.9 db noted in these cases. Success rate of 78% achieved and failed cases were subjected to traditional post auricular method of myringoplasty under microscopic guidance. Myringoplasty with the help of collagen sheet material in an office based set up is an easy, minimally invasive and effective technique and it avoids need for major invasive intervention in a significant number of patients.
