LOCATING THE FACIAL NERVE

Postglenoid tubercleA modified pre-auricular approach to the TMJ and malar arch, BJOMS 17(1979), 91-103.

VARIOUS APPROACHES

• RETROMANDIBULAR• PREAURICULAR • RHYTIDECTOMY• ENDAURAL• SUBMANDIBULAR• INTRAORAL

RETROMANDIBULAR APPROACH

VESNAVER – PERIAURICULAR APPROACH 2005


RETROMANDIBULAR WITH MODIFIED TRANSPAROTID APPROACH


PREAURICULAR APPROACH

History –

• Early description by Blair – Inverted L incision

• Dingman and Grabb modified – Making the angle between vertical and superior portions of incision more obtuse and rounding the angle of intersection.

• Lempert and Shambaugh modified – Carrying the incision to varying degrees behind the tragus and into EAC , creating Endaural incision.

INTRAORAL APPROACH

• Steinhauser (1964) was the first to report a successful osteosynthesis following intraoral approach.

• Since then it has been used by Pape et al(1980), Horch et al (1983), Kitayama (1989)

• It requires an incision through the vestibular mucosa along the anterior edge of the ascending ramus and

the periosteum and masseter are reflected.• Miniplates are fixed by means of a transbuccal trocar or an

angled screwdriver.

Intraoral Incision

Endoscopic



ENDOSCOPIC APPROACH

Equipment – • 30° angle 4mm diameter endoscope ( Karl Storz , Tuttlingen , Germany ) • Xenon light source • Suction and Irrigation device• Contra-angled handpiece


COMPLICATIONS• Nerve injury -temporary -permanent• Sialocele• Infection• Hematoma• Bad scar.


POINTS TO REMEMBER

PREAURICULAR APPROACH :• High condylar fractures• Incision within 8mm• Temporal extension• Facial nerve identification

RETROMANDIBULAR APPROACH :• Subcondylar fractures• Modified transparotid dissection• Horizontal mattress suture.
