Key points:
- MMN palsy and it’s pseudo-palsy have similar presentations
- These conditions have markedly different prognoses for the patient and
clinician.
- Both of the MMN and platysmal function are inherently at risk during
neck dissection
- The differentiation is a challenge to clinicians, this is evidenced in
the literature.
- The authors present a simple, robust method of differentiation between
the two palsies, along with the anatomical relevance. Allowing
appropriate reassurance, therapy and management can be undertaken
