External Nose: Start

PDF page 4, heading: External Nose (printed page 79)

1. External nose kis cheez se bana hota hai?

PDF ke according external nose ka framework osteocartilaginous hota hai.

Osteo = bone wala part
Cartilaginous = cartilage wala part

Iska matlab: naak ka external shape sirf bone se nahi banta, bone aur cartilage dono milkar bante hain.

2. Upper one-third of external nose

External nose ka upper 1/3rd part do nasal bones se bana hota hai:

2 nasal bones

Yani naak ke upper portion mein right aur left side ki nasal bones hoti hain.

3. Lower two-thirds of external nose

External nose ka lower 2/3rd part various cartilages se bana hota hai. PDF mein ye cartilages di hui hain:

Upper lateral cartilage
Lower lateral cartilage / alar cartilage
Lesser alar cartilage / sesamoid cartilage
Septal cartilage

Ab ek-ek ko simple way mein samjho:

A. Upper lateral cartilage

Yeh upper part ke cartilage framework ka hissa hai.
Bone ke neeche wale area mein aata hai.
External nose ke lower two-thirds ke support mein contribute karta hai.

B. Lower lateral cartilage / Alar cartilage

Isse alar cartilage bhi bolte hain.
Naak ke ala, yani nostril ke side wale fleshy wings, ke framework se related cartilage hai.
Isliye iska naam alar cartilage hai.

C. Lesser alar cartilage / Sesamoid cartilage

Isko PDF mein do names diye hain:
- Lesser alar cartilage
- Sesamoid cartilage
Yeh bhi lower two-thirds ke cartilaginous framework ka part hai.

D. Septal cartilage

Yeh nasal septum se related cartilage hai.
External nose ke cartilaginous framework mein include hota hai.

Diagram 1 ka main point

Diagram 1 ko dekhte waqt yaad rakhna:

Upper 1/3 = 2 nasal bones
Lower 2/3 = cartilages
- upper lateral
- lower lateral/alar
- lesser alar/sesamoid
- septal cartilage

Short recall line

“Upper one-third bony, lower two-thirds cartilaginous.”

4. Musculature

Isi page par next heading Musculature di hui hai aur Figure 2 diya hai.

PDF text mein is page par muscles ke individual names written form mein nahi diye gaye hain, sirf musculature ka diagram diya hai. Isliye diagram ko dekhkar muscle locations identify karni hain, lekin PDF ke bahar se names ya extra details add nahi kar raha hoon.

Page 4 ka final revision

External nose = osteocartilaginous
Upper 1/3 = 2 nasal bones
Lower 2/3 = cartilages:
1. Upper lateral cartilage
2. Lower lateral/alar cartilage
3. Lesser alar/sesamoid cartilage
4. Septal cartilage
Iske baad musculature diagram diya hai.

Next sequence: PDF page 5, printed page 80: skin covering, rhinophyma, basal cell carcinoma, parts of external nose, vestibule, aur nasal valve.

External Nose

PDF page 5, printed page 80

1. Skin covering of external nose

PDF ke according skin har jagah same thickness ki nahi hoti:

Nasal bones aur upper lateral cartilages ko cover karne wali skin thin hoti hai.
Alar cartilages ko cover karne wali skin thick hoti hai.
Alar cartilage wali thick skin mein sebaceous glands present hote hain.

Sebaceous glands kya hoti hain?

Yeh skin ke glands hote hain. PDF ke context mein important point yeh hai ki alar cartilage ke upar wali thick skin mein ye glands hote hain.

2. Rhinophyma / Potato tumor

Kya hota hai?

Sebaceous glands ki hypertrophy, yani unka size badh jana, ko rhinophyma kehte hain.
Isko potato tumor bhi kaha gaya hai.

Kab dekha jata hai?

Yeh generally long-standing acne rosacea ke cases mein dekha jata hai.

Treatment

PDF mein do treatment options diye gaye hain:

Laser
Cold steel excision followed by skin grafting

Yani enlarged tissue ko laser ya surgical excision se remove kiya ja sakta hai; excision ke baad skin grafting ki ja sakti hai.

Figure 3 aur Figure 4 rhinophyma se related images hain.

3. Basal cell carcinoma

Kya hai?

Basal cell carcinoma nose ki skin ko involve karne wala most common malignant tumor hai.
Isko rodent ulcer bhi kaha jata hai.

Nose mein common sites

Tip of nose
Ala

Kaise appear kar sakta hai?

PDF ke according basal cell carcinoma present ho sakta hai as:

Cyst
Papule
Pearly nodule
Ulcer with rolled edges

Treatment

Excision with 3-5 mm margins
Cryotherapy
Radiotherapy

4. Various parts of external nose and their nomenclature

Figure 5

Is point par PDF ne external nose ke different parts ka nomenclature diagram diya hai. Is diagram ko label-based revise karna hai. Diagram ke baad next section Internal Nose start hota hai.

Internal Nose

5. Vestibule

Kya hota hai?

Nasal cavity ke entrance par jo skin-lined part hota hai, use vestibule kehte hain.

Isme kya present hota hai?

Sebaceous glands
Hair, jise vibrissae kaha gaya hai
Vibrissae ke hair follicles

Clinical point

Hair follicles mein Staphylococcus infection hone par vestibule area mein furuncles ho sakte hain.

Nerve supply

Vestibule ko infraorbital nerve ki branches supply karti hain.

6. Nasal valve

Is page par heading nasal valve se start hoti hai, lekin uske detail points next PDF page par continue hote hain.

External Nose

PDF page 6 | Printed page 81

Is page par pehle nasal valve complete hota hai, phir lateral nasal wall, aur phir inferior turbinate explain kiya gaya hai.

1. Nasal valve

Figure 6

Kya hai?

Nasal valve nasal cavity ka narrowest part hota hai.

Yani naak ke andar ka sabse tang area nasal valve hai. Air ko nasal cavity mein enter karte waqt isi narrow region se pass hona padta hai.

Boundaries

PDF ke according nasal valve ki boundaries:

Medially: Nasal septum
Inferiorly: Floor of nose
Laterally: Upper lateral cartilage ka lower border

Simple orientation

Direction	Structure
Medial side	Nasal septum
Inferior side	Floor of nose
Lateral side	Lower border of upper lateral cartilage

Angle

Nasal septum aur upper lateral cartilage ke superior part ke beech jo angle banta hai, woh 30° hota hai.

Yaad rakhne ka point

Nasal valve = narrowest part of nasal cavity + angle = 30°.

2. Lateral nasal wall

Figure 7

Nasal cavity ki lateral wall par 3 turbinates, ya conchae, hote hain:

Inferior turbinate
Middle turbinate
Superior turbinate

Meati kya hote hain?

Har turbinate ke neeche ek space hota hai, jise meatus kehte hain.

Isliye 3 turbinates ke corresponding 3 meati hote hain:

Turbinate	Neeche ka meatus
Inferior turbinate	Inferior meatus
Middle turbinate	Middle meatus
Superior turbinate	Superior meatus

Important point

All paranasal sinuses in meati mein open hote hain.
Middle aur superior turbinates ethmoid bone ke parts hote hain.

Yani:

Inferior turbinate alag bone hai, jiska detail isi page par next diya hai.
Middle aur superior turbinate ethmoid bone se related hain.

3. Inferior turbinate

Kya hai?

Inferior turbinate ek separate bone hai.
Yeh longitudinally arranged hota hai, yani length mein aage se peeche ki direction mein placed hota hai.

Attachments

Anterior attachment

Maxilla ke saath attach hota hai.

Posterior attachment

Palatine bone ke saath attach hota hai.

Beech ke attachments

Inferior turbinate in structures se bhi attached hota hai:

Lacrimal bone
Uncinate process of ethmoid

PDF ke words mein: lacrimal bone aur uncinate process of ethmoid ke beech bhi attachment hota hai.

4. Inferior turbinate ki mucosa aur humidification

Inferior turbinate ki bone ke upar:

Thick vascular mucosal tissue hota hai.

Yani inferior turbinate sirf bone nahi hai. Iske upar thick mucosal covering hoti hai jisme blood vessels ki vascular channels hoti hain.

Vascular channels ka direction

Vascular channels turbinate mucosa ke andar posterior se anterior travel karte hain.

Iska role kya hai?

Jab inspired air nasal cavity mein aati hai, toh us air ka vascular channels ke saath long duration tak contact hota hai.

Is prolonged exchange ka result:

Inspired air ki humidification hoti hai.

Simple understanding

Posterior-to-anterior vascular channels ki wajah se inspired air aur vascular mucosa ke beech moisture exchange ka time milta hai. Isliye incoming air humidify hoti hai.

Page 6: Quick revision

Topic	PDF point
Nasal valve	Nasal cavity ka narrowest part
Nasal valve medial boundary	Nasal septum
Nasal valve inferior boundary	Floor of nose
Nasal valve lateral boundary	Lower border of upper lateral cartilage
Nasal valve angle	30°
Turbinates	Inferior, middle, superior
Meati	Har turbinate ke neeche corresponding meatus
Middle and superior turbinates	Ethmoid bone ke parts
Inferior turbinate	Separate bone
Anterior attachment	Maxilla
Posterior attachment	Palatine bone
Other attachments	Lacrimal bone and uncinate process of ethmoid
Thick vascular mucosa ka role	Inspired air ki humidification
Vascular channels direction	Posterior to anterior

Next PDF page 7 mein inferior meatus, nasolacrimal duct, Hasner valve, lacrimal pump mechanism, aur middle turbinate ke 3 parts hain.

Yani naak ke andar airflow ke liye yeh sabse tang jagah hai.

Nasal valve ki boundaries

Side	Boundary
Medially	Nasal septum
Inferiorly	Floor of nose
Laterally	Upper lateral cartilage ka lower border

2. Inferior turbinate

Figure 7

Figure mein inferior turbinate dikhaya gaya hai.

3. Lateral nasal wall

Lateral nasal wall mein:

3 turbinates / conchae hote hain:
1. Inferior turbinate
2. Middle turbinate
3. Superior turbinate
Har turbinate ke neeche ek meatus hota hai. Isliye:
1. Inferior turbinate ke neeche = inferior meatus
2. Middle turbinate ke neeche = middle meatus
3. Superior turbinate ke neeche = superior meatus

Important point

All paranasal sinuses inhi meati mein open hote hain.
Middle aur superior turbinate ethmoid bone ke parts hote hain.

4. Inferior turbinate

Kya hai?

Inferior turbinate ek separate bone hoti hai.
Yeh longitudinally arranged hoti hai, yani aage se peeche ki taraf length mein placed hoti hai.

Attachments

Anteriorly

Maxilla se attached hoti hai.

Posteriorly

Palatine bone se attached hoti hai.

In between

Lacrimal bone
Uncinate process of ethmoid

se bhi attached hoti hai.

5. Inferior turbinate ki mucosa aur function

Inferior turbinate ki bone ko thick vascular mucosal tissue cover karta hai.
Is mucosa ke andar vascular channels posterior se anterior direction mein travel karte hain.

Iska result kya hota hai?

Inspired air ka in vascular channels ke saath long duration tak moisture exchange hota hai.
Isse inspired air ki humidification hoti hai.

Simple line

Inferior turbinate ki thick vascular mucosa inspired air ko humidify karti hai.
