Presentation on theme: "The Face and Facial Expression"— Presentation transcript:
1 The Face and Facial Expression 235 Human AnatomyDr Stuart BuntUse video Face and faces, shows a variety of facial types, Rembrandt, Fergie, Aborigines etc.Slides:RC2 Buccinator and orbicularis orisRC3 facial muscles, cartoon from frontRM3 Embryo showing pharyngeal arches from the sideRC11 facial muscles from side like GrantsNOTE: for next year get slides from Clinical Anatomy, case studies..nice pictures for slides (scan?)
11 Problems with eye closure 7th nerve paralysisGeneral paralysis
12 Lymphatic Drainage Maxillary and anterior mandibular region Ant. Middle and Post. submandibular nodesvery tip to submental nodesAnterior Temporal, zygomatic and posterior manidibular regionsParotid nodesEarretroauricular and subauricular nodesAll drain into the cervical lymph nodes around the jugular
14 Nerve Supply Entirely by 7th Nerve Entirely motor except taste from ant 2/3 of tongueAlso supplies tensor tympani of same sideNOT upper eyelid3rd Nerve
15 The Facial NerveAuditory and facial nerve enter internal auditory canalFibres leave for Pterygo-palatine ganglion/otic ganglionExternal petrosal nerveChorda tympani to tongueThrough facial canal in mastoid
16 Clinical Evaluation “Upper Motor Neuron” “Lower Motor Neuron” cortex controls lower opposite faceforehead and eye closure dual consensual reflexes“Lower Motor Neuron”all muscles on oneside affectedtaste affected
17 7th nerve damage Bell’s palsy pain around ear no sensory impairment complete palsyrapid recovery(2-8wks)Entrapment in facial canal after infection?steroids in severe cases where taste affected
18 Other 7th nerve lesions Ramsay-Hunt syndrome Hemifacial spasm Herpes Zoster of 7th nervevery severe pain in earvesciclespoor recoveryHemifacial spasmirritation of nerve by blood vessel?
