Laser microdissection (LMD) has been used to isolate groups of cells and single cells from numerous tissues. In this chapter, we describe a technique for isolating individual spiral ganglion cells from archival formalin-fixed, celloidin-embedded (FFCE) human temporal bone sections. The DNA isolated from these single cells is suitable for analysis with a duplex real-time polymerase chain reaction (PCR) methodology to quantify the mitochondrial DNA (mtDNA) deletion level present.
