Polyethylene implants in nasal septal restoration.

IMPORTANCE Numerous techniques have been described to repair nasal septal perforations (SPs). However, many are technically challenging, with varying degrees of success. OBJECTIVE To evaluate the use of polyethylene (Medpor; Porex Technologies) implants in the closure of nasal SPs. DESIGN AND SETTING Prospective cohort study in an academic research setting. PARTICIPANTS Fourteen patients with a nasal SP were identified between March 1, 2008, and February 1, 2011. INTERVENTION Each patient underwent repair of the nasal SP with a polyethylene orbital sheet implant. After measuring the size of the SP, the implant was trimmed and shaped to fit appropriately. The implant was then placed between bilateral mucoperichondrial flaps using an endonasal approach. MAIN OUTCOME AND MEASURE Successful closure of the nasal SP with an intact polyethylene graft and complete remucosalization by the 1-year follow-up visit. RESULTS The most common initial symptoms of SPs were nasal obstruction, crusting, and epistaxis. The SPs ranged from 0.5 to 4.0 cm in diameter. Thirteen of 14 patients (93%) who underwent repair of their nasal SPs with a polyethylene implant had successful closure. CONCLUSION AND RELEVANCE The use of polyethylene implants is effective and technically easy and is associated with low patient morbidity because it does not require the harvesting of tissue from other donor sites.
