Pseudoptosis after Aberrant facial nerve regeneration (AFR): an under-recognized entity
Aberrant facial nerve regeneration (AFR) is not well recognized as a cause of pseudoptosis. Signs of AFR includes pseudoptosis, narrow palpebral aperture and prominent nasolabial fold on side of paralysis.
We present a series of six cases who had a significant pseudoptosis after facial nerve paralysis (FNP). All patients had a prominent nasolabial fold on the side of paralysis and a narrow palpebral aperture which further narrowed on the jaw movements. Margin Reflex distance (MRD)1 and MRD2 were reduced in all cases on the side of FNP. Levator palpebrae superioris (LPS) action and Bell’s phenomena were good in all the cases. All the cases were diagnosed as old lower motor neuron FNP with pseudoptosis due to AFR.
In conclusion, AFR as a cause of pseudoptosis is less well recognized. It is important to keep in mind this entity for proper management and to prevent the patient’s dissatisfaction.
