LATERAL VIEW OF NOSE AND PHARYNX

hello everyone in this presentation we'll learn important things regarding lateral wall of nose and pharynx starting with the lateral wall of nose the important things that you have to keep in mind regarding lateral wall of nose is the turbinates or the conquer so they're superior conquer middle conquer and inferior conquer the superior conquer is smallest whereas the infidel conquer is the largest out of all the three conquer are turbinates these conquer overlies the Miatas so the space beneath this conquer is called as me artists their superior middle and inferior me artists out of all the inferior me artists is the largest so the structures that drains into these me artists is very important so here you can see starting with spin or delayed sinus so spin oval sinus drains into spino with model rhesus so spinodal sinus drains into spino a the model rhesus whereas the posterior is the modulated sinuses so ether model sinus is divided into anterior middle and posterior portion with model air sinus drains into superior me artists there as anterior middle maxillary sinus and frontal sinus drains into meeting me artists here you need to understand an important thing middle meatus is divided in divided into 2 that is the structures that drains into bulla its modulus and the structures that drain into I add a semi linens so bullet models is a rounded elevation on which only middle is model a sinus drains into there as hiatus a millionairess is a semilunar sulcus into which maxillary sense anterior it model sinus and frontal sinus train into whereas the structure that drains into inferior Miatas is nasolacrimal duct so naso like lemon drains into inferior mirrors so this nasolacrimal duct is guarded by valve wash has not so it is called guarded by value of fastener edie inferior meters so there is something called as Cecil backs plexus also called as epistaxis area so it is the area where it is a common set of bleeding in the lateral wall of nose so it is this area is located at anterior inferior part of the nasal septum and the arteries that are associated with Kissel backs plexus are Pinot Palatine artery anterior it small artery greater Palatine artery and Sceptile branch of superior level artery so these are the arteries that are associated with epistaxis area are also called as Kissel bags area or Kissel bags triangle moving on to Friday s so firings is divided into three parts the nasal part that is nasopharynx also called as AP pharynx which extends from the base of the skull to soft palate as you can see in the diagram the oral part that is oropharynx which extends from hard palate to hyoid bone the laryngeal part also called as laryngeal pharynx or hypopharynx which extends from upper border of epiglottis to lower border of cricoid cartilage so the PI reformed fossa which is also called a Smuggler's pouch or Smuggler's fossa is located in the laryngeal fairings this slide shows you the weak spot between the muzzles of fairings the main one is Kilian stations so Kilian stations is the weakest area of pharynx which is located between public thoroughfare injures and longitudinal crike of ranges so the Killians day cells is present between pyro fairness and Clicquot fairness whereas there is another weak spot that is lamers divisions which is located between cricopharyngeal and longitudinal muzzle of esophagus so what is the clinical significance of these vague spots so if the muscles that is cricopharyngeal and thyra fringes doesn't relax what happens is the food that we eat escapes through this area to form an pharyngeal pouch so Killians Dyson's is important clinically because it is a weakest area which leads to the formation of pharyngeal pouch also called as zingers diverticulum and the muscles involved are once again it is Theroux fairness and Clicquot fairness the structures passing between the constructors of fairings is also important here you can see the gaps the numbers are denoted with the gaps one two three and four so the first gap is between the base of the skull and superior constrictor also called as sinus of more gagney and these are the structures passing through this gap one whereas the gap two is between superior constrictor and middle constrictor the gap 3 is between middle and inferior constrictor whereas the last gap is between inferior constrictor and esophagus these are the structures that are passing between the Constructors remember middle constrictor is considered to be a fan-shaped in muzzles of fairings there is one more term called passive enriched so passive enriched is important clinically because the synergistic effect of passive and still along with the soft palate makes the food enter into oropharynx instead of nasopharynx so passive enriched is formed with the help of palatov arrangers so the muscle responsible or the muscle which forms most of the part of passive and is palliative arranges there is some lymphatic chain in the pharynx which is important that is denoted as walnuts lymphatic ring so all days lymphatic ring consists of four types of tonsils that is fair angel downs and also called as arena transom tubal towns in Palatine tonsils and lingual tonsils so this is the varlets chain of lymphatic chain which consists of or tonsils pharyngeal tubule palate and and lingual tonsil thank you all that's all with
