Transmastoid middle fossa craniotomy repair of superior semicircular canal dehiscence using a soft tissue graft.

Objective: To describe the successful surgical treatment of 5 cases of superior semicircular canal dehiscence via a transmastoid middle fossa craniotomy using a soft tissue graft.

Design: Case report.

Setting: Private practice otologic referral center.

Orbital floor reconstruction using porcine small intestinal submucosa.

Background: We conducted a prospective, controlled, blinded pilot study to demonstrate that repair of induced rabbit orbital floor fractures with Surgisis ES (Cook Biotech Inc, West Lafayette, Ind) provides adequate orbital content support while promoting mucosal and bone regeneration of the fracture site.

Material/methods: Ten New Zealand white rabbits underwent induced bilateral controlled (5mm) orbital floor fractures under anesthesia. In each rabbit, Surgisis ES, an acellular, freeze-dried soft tissue matrix derived from porcine small intestinal submucosa, was implanted subperiosteally to repair one orbital floor fracture through a transconjuntival approach.

Lip augmentation with porcine small intestinal submucosa.

Objective: To relate our initial experience using an acellular, soft tissue matrix derived from porcine small intestinal submucosa (Surgisis; Cook Biotech Inc, West Lafayette, Indiana) for lip augmentation.

Design: A prospective, uncontrolled case series examining the results of lip augmentation using Surgisis in patients presenting to an academic otolaryngology/facial plastic surgery office.

Results: Nineteen Surgisis implants were placed in 8 patients.
