Abstract
A study to compare tympanoplasty between endoscopic and microscopic approach was conducted at NMCTH. Patients diagnosed as chronic otitis media – mucosal type with age of 13 years and above were included in the study. Audiometric test was done before and 6 weeks after surgery. Seventy cases were included for the study with random allocation of cases each in endoscope group and microscopic group respectively. Graft uptake results were assessed after 6 weeks and postoperative hearing were evaluated and compared within and between the two groups. In endoscopic group and microscopic group, the graft uptake rate was 91.4% and 88.5% respectively with no significant difference (p = 0.71) in the graft uptake rate between the groups. The mean pre and post-operative air bone gap in endoscopic group and microscopic group were 34.59 dB±8.02, 21.97±8.60 dB and32.42±10.08 dB, 18.55±8.49 dB respectively. This showed a highly significant difference in both groups(p < 0.001), showing improvement in the hearing after surgery in both the groups. The mean air bone gain were 12.62 dB and 13.87 dB in endoscopic and microscopic group respectively, with no significant difference between the groups (p = 0.553). The graft uptake rate and hearing results with endoscopic technique is comparable to that of microscopic technique. However, the endoscopic technique requires shorter operative time than the microscopic technique. Therefore, we recommend the use of endoscope for tympanoplasty in hospital as well as in camps.
Highlights
Tympanoplasty is defined as an operation involving reconstruction of the tympanic membrane and/or the ossicular chain
This study included patients aged 13 years and above diagnosed with chronic otitis media mucosal type with large perforation and patients willing to undergo tympanoplasty in the hospital
Odd number were included in microscopic group whereas even number were included in endoscopic group
Summary
Tympanoplasty is defined as an operation involving reconstruction of the tympanic membrane and/or the ossicular chain. Myringoplasty is a tympanoplasty without ossicular reconstruction. Over the years many methods have been used for closing perforations. The most widely used and accepted method is underlay graft of temporalis fascia or sometimes perichondrium.[1]. Tympanoplasty was first described by Wullstein[2] and Zollner[3] in 1952 as the mainstay for tympanic membrane reconstruction. Different grafting materials that have been used for reconstruction are mesenchymal tissues, including vein, fascia, perichondrium and periosteum.[4,5,6,7,8,9,10] But the most widely used graft material is temporalis muscle fascia.[11]
