Abstract

Objective:

To compare anatomical and audiological outcomes of ring versus ‘Mercedes-Benz’ cartilage-perichondrium graft tympanoplasty in patients with pars tensa cholesteatoma.

Study design:

Prospective clinical study.

Setting:

Otolaryngology department, Tanta University Hospital, Egypt.

Patients and methods: Over three years, 60 ears in 60 patients underwent surgery for either sinus or tensa retraction cholesteatoma, reconstructed using either a ring-shaped (30 ears) or Mercedes-Benz symbol shaped (30 ears) cartilage-perichondrium graft, with at least two years' follow up. Post-operative drum perforation and retraction, cholesteatoma residue and recurrence, middle-ear effusion, and hearing acuity were monitored.

Results:

Anatomical outcomes were equivalent in both groups, but slightly better in the Mercedes group. Hearing improved significantly in both groups (pre- vs post-operative results), but significantly more so in the ring group. Within-group hearing outcomes were unaffected by cholesteatoma type or tympanoplasty type.

Conclusion:

The Mercedes-Benz technique may be superior to the ring technique in preventing neodrum retraction. However, the ring graft technique had better hearing outcomes, perhaps due to its more physiological design.
