Study summary

This is a prospective, randomized trial to evaluate canal wall down mastoidectomy (CWDM) healing outcomes using Biodesign® small intestine submucosa graft compared to autologous temporalis fascia graft.

Read the detailed description

Patients 18 or older will undergo primary canal wall down mastoidectomy. Patients with known biologic sensitivity or cultural objection to use of porcine materials will be excluded.

Data will be derived from the medical record and surgeon reports as detailed on pre-op and follow-up forms. Variables collected include age, gender, medical co-morbidities, body mass index, pre-operative audiometric values (including word recognition score, pure tone average, and air bone gap), side of surgery, size of operative cavity, infectious state (draining versus dry), exact surgical procedure, presence of cholesteatoma, time to dry cavity, time to complete epithelialization (as observed directly by the surgeon), and post-operative complications (such as persistent perforation, drainage, granulation tissue formation, and facial nerve outcomes). Dates and patient number will be recorded. Patients will be randomly assigned using randomization software, whereby patients will be assigned a sequential research number that is pre-randomized to one research arm. The study cannot be blinded, as the surgeon will be able to identify which graft will be used. De-identified photographs of the post-operative outcomes at each time point will be recorded photographically. Three physicians will review these photographs without prior knowledge of the treatment arm.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 19, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
