Table 3 Relation of MMN with facial vessels

Batra

Embalmed cadavers, 50 facial hemi-halves

MMN superficial to FA and FV in 100% cases

Kim

Cadaver dissection 85 facial halves

Relation to FA:

Superficial—42%

Deep—4%

On both sides—54%

Relation of cervico-facial div to retromandibular vein:

Lies in lateral aspect of vein in 83% specimens

Karapinar

Cadaver dissection of 44 facial halves

Relation to FA:

97.7%—MMN lies laterally

1 specimen—MMN lies between the FA and FV

S Toure

Cadaver dissection study on 54 cadavers

Crossed the facial vessels 24 mm posteroinferior from the angle of mandible

Lateral to facial vessel bundle—51 cases

Medial to FA and lateral to FV—2 cases

Medial to FV and lateral to FA—1 case

Potgieter

Embalmed cadaver dissection of 36 facial halves

MMN lies 2.4 mm superior to a point just anterior to FA (point B)

Lies 10.7 mm superior to a point 2 cm anterior to point B

Ziarah

110 cadaveric cervico-facial halves

MMN branches invariably passed superficial to anterior FV

Relation to FA variable

Dingman

100 embalmed cadaveric dissections

Posterior to FA—81% lies above LBM

Anterior to FA—19% lies below LBM

Wang

120 cadaveric facial halves

Anterior to FA—90% above LBM, 10% below LBM

Posterior to FA—67% above LBM, 33% passed in an arc of 0.95 cm below LBM

Relation to FA:

Superficial to FA—83%

Both superficial and deep to FA—15%

Deep to FA—2%

Superficial to retromandibular vein in 100% cases

G Toure

Cadaver dissection on 62 half heads

MMN lies lateral to FV in 95% cases and hence considered a more reliable landmark.

Huu-Mu Yang

Cadaver dissection of 12 embalmed and 4 fresh cadavers

MMN located ≤ 10 mm from intersection of FA and mandible in 89.7% cases.

MMN found below intersection of FA and mandible in 44.8% cases.
