Conditions involving external nose
Dr T Balasubramanian
Importance of nose



Nose is the most
prominent portion of
face
More prone for injuries
Disorders of external
nose could be a
indicator of a systemic
disorder
Introduction

Disorders of external nose commonly involves skin

Whole of dorsum of nose is skin lined

The vestibule of the nose is skin lined

Since the common problems involve the skin in this
area a recap of dermatological terms is a must
Dermatological terms




Macule – This is a flat lesion within the skin
Papule – Circumscribed raised lesion of dermis /
epidermis less than 1 cm in diameter
Nodule – This is a papule greater than 1cm in
diameter
Plaque – Is a large superficial lesion whose surface
area is greater than that of its height and its margins
are irregular
Acute nasal infections


Bacterial – Vestibulitis, Erysepelas, and impetigo
Viral – Herpes, Warts, Molluscum contagiosum,
Measles
Acute vestibulitis




Infection of nasal
vestibular skin
Commonly arises from
hair bearing region of
vestibule
Staph aureus is the
commonly involved
organism
Common in children
due to nose picking
Acute vestibulitis symptoms

Severe pain

Fever

Swelling

Tenderness

In recurrent vestibulitis diabetes to be ruled out
Vestibulitis treatment

Broad spectrum antibiotics

Antiinflammatory drugs

Local application of antibiotic cream

Squeezing to be avoided – could cause cavernous
sinus thrombosis
Dangerous area of face


Infection can traverse
via the valveless facial
vein
Via its supraorbital and
superior ophthalmic
branches spread to
cavernous sinus
Impetigo

Superficial contageous infection involving the skin
of the vestibule

Group A streptococcus is involved

Two forms bullous and non bullous forms

Staphylococcal infection leads to widespread
shedding of epidermis (scalded skin syndrome /
Lyell's disease)
Erysipelas

Acute infection of skin lined vestibule

Streptococcus implicated

It enters via fissures in the skin

Pain, heat, swelling and vesiculation

Peau d ' orange appearance
Herpes simplex lesions

Type I Herpes virus is involved

Lips, perioral region and cheek involved


Infections from this area spreads to involve the
vestibule of the nose
Antibiotics help in preventing secondary infections
Herpes zoster lesions



This virus is responsible for chicken pox lesion
Involvement of maxillary division of V nerve causes
vesicles over cheek and nasal vestibule areas
Infection gets transmitted via fluid present in the
vesicles
HPV infections

Warts

Localised neoplastic growth of epidermis

Self limiting

Cryotherapy / cauterization
Lesions formed by HPV

Warts

Three types of lesions are possible

Hyperkeratotic lesions, verruca vulgaris, common
wart

All these lesions appear raised

Usually self limiting
Wart
Verruca vulgaris
Molluscum contagiosum


DNA virus of Pox group is involved
Appears as small papules white and waxy with a
dome

Not contagious

Self limiting

Can be cauerized
Chronic infections

Vestibulitis

Lupus vulgaris

Syphilis

Lupus erythematosis

Acne rosacea
Chronic vestibulitis

Repeated fissuring of vestibule

Crust formation

Epistaxis is possible when the pt rubs the nose

Diabetes to be excluded
Lupus vulgaris

This is a type of cutaneous tuberculosis involving
the skin of the vestibule

Direct inoculation of skin causes scrofuloderma

Post primary tuberculosis



Initially lesions are nodular resembling apple jelly
hence the term apple jelly nodules
Extensive tissue destruction is seen causing nasal
deformities.
Nasal cartilages are predominantly destroyed
Syphilis

Primary syphilis involving the vestibule is common

Firm painless nodule

Rubbery cervical adenopathy

Rhinitis ”syphlitic snuffles”

Secondary syphilis causes vestibular skin fissuring


Tertiary syphilis in the form of gumma is common in
the nose. There is extensive bony destruction.
Tenderness over bridge of nose & nocturnal pain
Congenital syphilis

Presents within few weeks after birth

Purulent rhinorrhoea ”Snuffles”

Fissuring around vestibule

Saddling of nose is seen at the age of 3-4
Yaws

Extragenital infection of T Pertenue

Common in children of Africa

Extensive disease can lead to midfacial destruction

Gondou type of yaws causing bilateral rounded
swelling of nasal process of maxilla
Lupus erythematosis

Autoimmune disorder

Multi organ disorder

Involves skin in the vestibule

Photosensitivity
Acne rosacea

Involves the skin over the face

Skin lining of the nasal vestibule is also involved

Skin shows reddish patches with ruptured
subcutaneous blood vessels

Nose becomes red and bulbous

Burning / stinging sensation over face +

Avoid exposure to sun
Neoplasms

Benign – Papilloma, Kerata acanthoma

Malignant – Rodent ulcer, sq cell carcinoma
Keratoacanthoma





Benign tumor arising from hair follicles of skin over
the nose
Skin exposed to sun causes more problems
Presents are firm, round, reddish / flesh colored
lesion
Lesion may turn globular and may present with a
horny central keratotic plug
Shedding of this plug signals recovery
Traumatic conditions

Fracture nose

Septal hematoma

Saddle nose
Fracture nose

May be with or without displacement

Deformity of dorsum of nose

Tenderness / Swelling over nasal bone area / crepitus

X-ray nasal bones may reveal #

Closed reduction is preferred
Septal hematoma / abscess

May be caused by injuries / surgery in the nasal
septal area

Bilateral swelling of nasal septum with nasal block

Perichondrium stripped away from the cartilage


Cartilage necrosis occur within 36 hours if not
drained
Hematoma may give rise to septal abscess
Saddle nose



Occurs due to destruction of the bridge of nose
Destruction of osseous / cartilagenous portion of the
bridge of nose
Septal abscess / syphilis involving the nose may
cause this problem
Foreign bodies

Inanimate

Animate

Rhinolith
Conditions involving nasal septum

Deviated nasal septum

Dislocation of anterior portion of nasal septum

Septal perforatrion
Congenital conditions

Nasal dermoid

Gliomas

Choanal atresia
