  • 13. SOME RELATIONS OF LATERAL PTERYGOID MUSCLE<br />
  • 14. DEEP DISSECTION OF TEMPORAL & INFRATEMPORAL REGION AFTER REMOVING A PART OF RAMUS OF MANDIBLE WITH MASSETER & INSERTION OF TEMPORALIS MUSCLE<br />ZYGOMATIC ARCH <br />HAS BEEN REMOVED<br />
  • 15. ORIGIN & COURSE OF MAXILLARY ARTERY<br />
  • 16. MAXILLARY ARTERY:-ORGIN COURSE & BRANCHES IN INFRATEMPORAL FOSSA <br />
  • 17. BRANCHES OF MAXILLARY ARTERY<br />A.First Part:-<br /> 1.Deep Auricular Artery 2.Anterior Tympanic <br /> 3.Middle Meningeal Artery 4.Accessory Meningeal Artery<br /> 5.Inferior Alveolar Artery<br />B.Second Part:-<br />1.Deep Temporal 2.Pterygoid<br /> 3.Masseteric 4.Buccal<br />C.Third Part:-<br />1.Posterior Superior Alveolar 2.Infraorbital<br /> 3.Greater Palatine 4.Pharyngeal<br /> 5.Artery Of Pterygoid Canal 6.Sphenopalatine Artery <br /> [Terminal part of maxillary artery]<br />

  • 21. PTERYGOID PLEXUS OF VEINS<br />1-SITUATED around the lateral Pterygoid Muscle<br />2-Tributaries are those veins which accompany <br /> branches of maxillary artery<br />3-Plexus is draind by maxillary vein <br />4-Maxillary vein is only accompany to first part of <br /> maxillary artery <br />5-Maxillary vein unite with superficial temporal <br /> vein to form retromandibular vein<br />COMMUNICATIONS:-<br />1.With inferior orbital vein through the inferior <br /> orbital fissure<br />2.With cavernous sinus through emissary vein <br /> passing through foramen lacerum & ovale<br />3.With facial vein through deep facial vein<br />
  • 22. MANDIBULAR NERVE & ITS BRANCHES SEEN IN INFRA TEMPORAL FOSSA AFTER REMOVING A PART OF MANDIBLE <br />
  • 23. MANDIBULAR NERVE & ITS BRANCHES SEEN IN INFRA TEMPORAL FOSSA AFTER REMOVING A PART OF MANDIBLE <br />
  • 24. Branches of Mandibular Nerve:-<br />1.From Main trunk:-<br />[a] Meningeal branch <br /> [b] Nerve to Medial Pterygoid muscle<br />2.From Anterior division of trunk :-<br /> [a] Sensory-Buccal nerve <br /> [b] Motor branches to <br />Masseter [Nerve to masseter],<br />Temporalis[Deep Temporal nerves],<br /> Lateral PterygoidMsucle<br />3.From Posterior division of trunk <br /> [a] Auriculotemporal nerve <br /> [b] Lingual nerve <br /> [c] Inferior alveolar nerve<br />
  • 25. MANDIBULAR NERVE,ITS COURSE & BRANCHES IN INFRATEMPORAL FOSSA<br />
  • 26. OTIC GANGLION:-ITS CONNECTIONS<br />
  • 27. OTIC GANGLION<br />Introduction:-<br /> A peripheral parasympathetic ganglion which supply secretomotor fibres to parotid gland<br />Topographically:-<br /> It is connected to Mandibular nerve but functionally to Glossopharyngeal Nerve<br />Size & Situation:-<br />2-3 mm in size & is situated in infratemporal fossa just below the foramen Ovale between Mandibular nerve [lateral side ]& Tensor Veli Palatini muscle [medial side]<br />
  • 28. Connections & Branches:-<br />1. Motor or Parasympathetic Root:- By lesser petrosal nerve <br /> The pre ganglionic fibres from inf.salivatory nucleus –IX Cn.-to-<br /> tympanic branch-to-the tympanic plexus-to-the lesser <br /> petrosal nerve to- otic ganglion<br /> The Post ganglionic fibres from otic ganglion-through- <br /> auriculotemporal nerve –to- Parotd Gland<br /> [SECRETOMOTOR TO PAROTID GLAND]<br />2. Sympathetic Root:- Nerve fibres from plexus on the middle <br /> meningeal artery [ These are post ganglionic fibres from sup.cervical sympathetic ganglion]-to otic ganglion-to auriculotemporal nerve –to parotd gland <br /> [VASOMOTOR IN FUNCTION] <br />3. Sensory Root:-Sensory fibres from parotid Gland Through <br /> auriculotemporal nerve<br />
  • 29. 4.Other Connections to otic ganglion:-<br />1. A branch from nerve to medial pterygoid which passes as <br /> such through otic ganglion to supply Tensor veli palatini & <br /> tensor Tympani<br /> 2. The Chorda tympanic nerve is connected to otic ganglion.<br /> this connection provide an alternate pathway of taste from <br /> ant.2/3 of the tongue.<br />
