Anatomy And Physiology Of The Nose External nose: Pyramid in shape Consist Of osteocartilaginous framework Bony part:( upper 1/3) - 2 nasal bones -frontal process of maxilla 2. Cartilginous part :( 2/3 lower) -lateral cartilage - alar cartilage -lesser alar cartilage

Anatomy And Physiology Of The Nose B. Internal nose : Divided Into Right &left nasal cavity by nasal septum Each nasal cavity communicate with the exterier through naris or nostril and with nasopharynx through choana Each nasal cavity consist of :a skin-lined portion –the vestibule and a mucosa- lined portion ,the nasal cavity proper

Naris Nasal septum
Slide 6-

Anatomy And Physiology Of The Nose Lateral wall: - 3 turbinates - 3meatus : Inf meatus :nasolacrimal duct open in the anterior part middle meatus : opening of anterior sinus group (frontal sinus – maxillary sinus – anterior ethmoid cells) Superior meatus :opening of post ethmoidal cells

Anatomy And Physiology Of The Nose Function of the nose : Respiration Air conditioning of inspired air Filtration &Purification Temperature control Humidification Protection of lower airway Mucocilliary mechanism Enzymes and immunoglobulins Sneezing Vocal Resonance Olfaction
Slide 9-

Disease of the nasal septum 1-Deviated nasal septum Aetiology : occur following previous nasal trauma Result from asymmetric septal development possibly following birth trauma Clinical features : Present as unilateral nasal obstruction and less commonly epistaxis The inf and middle turbinates on the side opposite the septal deflection often undergo compensatory hypertrophy Management: If the symptom warrant, the septum can be positioned in the midline in the operation of septoplasty and submucosal resection
Slide 10-

Deviated
Slide 11-

Disease of the nasal septum 2- septal haematoma :( a collection of the blood beneath the mucoperichondrium and posteriorly the mucoperiosteum of the nasal septum ) Aetiology : Usually complication of nasal trauma (accidental or iatrogenic) Rarely a spontaneous haematoma can occur in a bleeding diathesis Clinical features : Nasal obstruction with widening of the septum on inspection Management : In the acute stage treat by incision and drainage After 48 h ; organization of haematoma occurs and evacuation of the clot is difficult Antibiotics are given to prevent secondary infection

ACUTE &Chronic RHINITIS Treatment: 1)medical Nasal irrigation &removal of crust: Warm nasal saline Alkaline solution: -1teaspoon of soda bicarbonate -1teaspoon of sodium biborate -2 part Nacl/280ml water 25%glucose in glycerin :painting the nose after crust removal local ATB
Slide 34-

ACUTE &Chronic RHINITIS 2)surgical: Young operation: close both nostrils for 6 month. nnarrowing the nasal cavities: sub mucosal injection of Teflon. insertion of fat ,cartilage under the mucoperiosteum medial displacement of lateral wall of the nose

Allergic Rhinitis Exanimation Post nasal drip Pale , oedematous mucosa Turbinate swollen with thin watery or muciod discharge
Slide 41-

Allergic Rhinitis Investigation : ↑ Eosinophils ( WBC) Nasal smear: eosinophils+++ Skin test: identify the specific allergen RAST (Radioallergosorbent test ): - measure the specific IgE concentration

Non – Allergic Rhinitis Vasomotor Rhinitis (VMR) : same symptoms as seen in All rhinitis with predominance of nasal obstruction which is alternate from side to side Skin test (-) Same treatment, as in nasal allergy
Slide 45-

Non – Allergic Rhinitis Other Form of Non- allergic Rhinitis : Drug-induced rhinitis: Anti- hypertensive drug ( propranolol , methyl dopa,reserpine) Neostigmine Contraceptive Rhinitis medicamentosa Excessive use of topical decongestant ++++ Rhinitis of pregnancy : Hormonal factors Care should be taken while prescribing drugs :oral antihistamine must be avoided
Slide 46-

Non – Allergic Rhinitis 4. Emotional rhinitis Anxiety, Tension , hostility , humiliation Psychological treatment Imipramine (antidepressant and anticholinergic ) found useful 5. Rhinitis due to hypothyroidism : ↓Sympathetic system → ↑ parasympathetic system → nasal obstruction Treatment: thyroid hormone 6. Non air –flow rhinitis : Seen in Patients of laryngectomy and tracheostomy ,choanal atresia

Slide 49-

Epistaxis Bleeding from inside the nose ENT emergency Epistaxis is a sign and not a disease Blood supply of nose Internal carotid system : Anterior ethmoidial artery Posterior ethmoidial artery Braches of opthalmic Artery
Slide 50-

Epistaxis Difference between anterior and posterior epistaxis Anterior epistaxis Posterior epistaxis Incidence More common Less common Site Mostly from little’s area or anterior part of lateral wall. Posterosuperior part of nasal cavity; often difficult to localise the bleeding point. Age Mostly occurs in children or young adults. after 40 years of age. Cause Mostly trauma Spontaneous; often due to hypertension or arteriosclerosis. Bleeding Usually mild, can be easily controlled by local pressure or anterior pack. Bleeding is severe, requires hospitalitisation ; postnasal pack often required.
Slide 51-

Epistaxis External carotid system: Sphenopalatine artery branch of maxillary artery . Branch of facial artery to nasal vestibule Little area Situated in the ant – inf part of nasal septum Most causes of epistaxis originate from this area There is rich vascular anastomosis In this area “kiesselbach’s plexus ”
Slide 52-

Epistaxis A) Causes of epistaxis : Traumas Infection F.B Tumor Benign Haemangiomas Papiloma Juvenile angiofibroma

Epistaxis Liver disease cirrhosis Kidney disease chronic nephritis Drugs anticoagulant therapy 6. Idiopathic : 90% causes B) Classification of epistaxis: 1.Antirior epistaxis 2.Post epistaxis
Slide 55-

Epistaxis Management: in any cause of epistaxis I is important to know 1)Mode of onset 2)Duration and frequency of bleeding 3)Amount of blood loss 4)Side of epistaxis 5)Whether Ant or post epistaxis 6)Any known bleeding tendency in the pt on his family 7)History of drugs intake (analgesics , anticoagulant etc.. ) 8)Medical illness history ( HTN, cirrhosis, leukemia )
Slide 56-

Epistaxis Intiales measure to stop bleeding consist of: pinching the nose with thumb& index for 5 minute If bleeding vessel seen : cautery AgNO3 ant nasal packing for ant epistaxis Removal after 2-3 days Systemic ATB to prevent infection Post nasal packing for post epistaxis

Epistaxis General Measures in Epistaxis: Make the Pt sit up with a back rest and record any blood loss taking place through spitting or vomiting Reassure the Pt .mild sedation should be given Keep check on pulse , BP and respiratory rate Maintain hemodynamic. Blood transfusion may be required Antibiotic may be given to prevent sinusitis , if pack is to be kept beyond 24 hours
Slide 63-

Epistaxis 6. Intermittent oxygen may be required in Pt with bilateral packs because of increased pulmonary resistance from nasopulmonary reflex 7. Investigate and treat the Pt for any underlying local or general cause

Miscellaneous Disorders of Nasal Cavity 1)Foreign bodies (FB) children+++ any child presents with unilateral foul smelling nasal discharge FB must be excluded X-rays is useful to confirm the diagnosis only in radio-opaque objects treatment :removal
Slide 65-

treatment :removal X-rays for F.B
Slide 66-

Miscellaneous Disorders of Nasal Cavity 2)Rhinolith: stone formation in the nasal cavity treatment: removal under GA 3)Nasal Myiasis (Maggots in Nose ): maggots are larval forms of flies They infest nose, nasopharynx and paranasal sinuses causing extensive destruction Clinical feature : First 3-4 days : nasal irritation , blood – stained discharge, ooze from the nose After 4 days : maggots crawl out of the nose , foul smell Maggot cause extensive destruction of the nose ,sinuses soft tissue of face

Nasal synaechia : Adhesion formation between the nasal septum and turbinates Causes : Nasal surgery Nasal trauma Rhinoscleroma Treatment : Removal of synaechia Placing thin silastic sheet to prevent recurrences

Choanal Atresia: Congenital anomalies due to persistence of bucconasal membrane Bony 90%+++++ Membranous 10% Unilateral : ++++++ may remain undiagnosed until adult life Bilateral :++ complete or incomplete Complete& bilateral ( emergency +++++++( life threatening ) Diagnosis Presence of mucoid discharge in the nose Absence of air bubbles in the nasal discharge Failure to pass catheter from nose to pharynx Putting a few drops of dye ( methylen – blue ) into the nose and seeing it is passage into the pharynx Installing radio opaque dye into the nose and taking lateral film CT
