Nasal airway obstruction (external and internal nasal valve collapse)
Loss of oral competence
Facial paralysis management needs to be considered based on location and degree of functional loss. Facial paralysis may involve the entire face, a portion, or any combination (e.g. brow, upper eyelid, lower eyelid, midface, lower lip). Paralysis can be either complete or partial loss of function and it can be reversible or irreversible based on the cause of nerve/muscle injury.
No proximal or distal ending of facial nerve available
Imaging such as CT or MRI may be necessary in situations where the diagnosis or anatomy is uncertain. More details can be found in additional material, under the patient evaluation and management section.
