Surgical site infection
Due to their inevitable contamination, infection of trephine repulsion sites is common but usually self-limiting. Prolonged non-healing of cutaneous repulsion tracts should prompt an examination for the presence of intra-alveolar dental or bone fragments, or of saliva or food from oral leakage. Local infection and delayed healing can occur at standard buccotomy wounds (O’Neill et al. 2011) but rarely at MITT sites.
