Abstract
Introduction: Chronic traumatic Spinal Cord Injuries (SCI), leave a significant percentage of permanent motor and sensory disability. Transplantation of Olfactory Mucosa Autografts (OMA) at the lesion site is a hopeful procedure. We present a case-series of patients with SCI treated with OMA.
Material and methods: The AIS scale was utilized for neurologic evaluation. The features of the spinal cord lesion were determined by MRI. Neurophysiological studies were used in patients with clinical improvement. A program of rehabilitation after surgery was used at least for one year.
Results: Twenty patients underwent OMA (17 males, 3 females, age range: 22-40 years, mean age: 29.25±6.6 years).13 patients (13/20, 65%) had tetraplegia and 7 (7/20, 35%) paraplegia. Overall 80% of the patients were in ASIA score A and 30% score B. During the follow-up period, 9 patients presented improvement in ASIA scale estimation (9/20, 45%); 8 from A to B, and 1 from A to C. A complication rate of 25% was noted.All postoperative complications were minor and treated during in-hospital stay.
Conclusion: OMA in patients with SCI, offers minor clinical benefits in up to 45% of patients. Intensive rehabilitation is an important factor of maintenance and improvement of clinical and functional results obtained.
