Abstract
Objective: This study analyzes the impact of fat grafting on pulp-sensitivity disorders in patients who experienced fingertip injuries and developed cold intolerance and hyperesthesia.Material/Method: Patients over 10 years old were evaluated using the two-point discriminant score ( 2PDS), the monofilament test, and the McCabe Cold Sensitivity Severity Scale ( CSS) before and after surgery at 3, 6, and 12 months. Other evaluations included the Quick Dash scale ( Q-dash), the aesthetics and pain improvement, and patient satisfaction.For children under 10 years old, a parent questionnaire was asked about pain reduction and the ability of parents to trim their children's nails.Result: Seven patients ( 2 < 10 years old and 5 > 10 years old) who all presented sensitivity disorders following a fingertip injury and were operated on for a pulp fat grafting were analyzed. No significant effects were found on the two-point discriminant score ( 2 PDS), the McCabe Cold Sensitivity Severity Scale (CSS scale), the monofilament test, as well as the quality of life. Four patients experienced less pain and aesthetic improvement. No outcome occurred. A small quantity of fat ( 0,97 ml) was injected and patient satisfaction was good at 6.4/10. For the two children, it was easier for parents to cut their children’s nails.Discussion /conclusion: While no statistically significant improvement in pulp sensitivity was observed, there were subjective improvements in pain relief and aesthetic outcomes, particularly in children. For children, positive effects were found on pain and the facility for parents to cut their children's nails. More studies are required for children. Pulp fat grafting may be a therapeutic option for patients who suffer from fingertip injury.
