Abstract :
To compare the graft uptake and
postoperative hearing between cartilage rim augmented
fascia and temporalis fascia type I tympanoplasty.
Materials and methods: This prospective, longitudinal,
comparative, randomized and interventional study was
conducted at Department of ENT, Tribhuvan
University Teaching Hospital, Institute of Medicine,
Maharajgunj, Kathmandu for a period of 16 months
amongst fifty two patients of age 15 years and above
with the diagnosis of chronic otitis media mucosal with
high risk perforation and cases of revision type I
tympanoplasty with pure conductive or mixed hearing
loss divided equally into cartilage rim augmented fascia
tympanoplasty group and temporalis fascia
tympanoplasty group. Graft uptake and hearing results
were assessed after three months of surgery and
compared. A postoperative residual air-bone gap of 20
dB or less was considered a successful hearing outcome.
Results: Graft uptake rate in cartilage rim augmented
fascia group was 91.67% (22/24) and in temporalis
fascia group was 96% (24/25) with no statistically
significant difference in the graft uptake rate (p=0.609)
between the two groups. The mean pre and
postoperative air-bone gaps in the cartilage rim
augmented fascia group were 29.68±9.66 dB and
12.56±5.10 dB and in the temporalis fascia group were
28.02±8.21 dB and 12.5±5.37 dB respectively. There was
no statistically significant difference in successful
hearing results between the two groups (p=1.00).
Conclusion: The graft uptake rate and hearing results
of cartilage rim augmented fascia tympanoplasty are
comparable to those of temporalis fascia tympanoplasty.
Hence, cartilage rim augmented fascia type I
tympanoplasty can be an alternative for the repair of
high-risk perforations.
