What Is the Nasal Vestibule?

The nasal vestibule is a relatively large part of the anterior lower part of the nasal cavity, which is mainly located on the inner side of the nose wings and nose. The inner surface of the nasal vestibule is lined with skin and has rough nose hair, which has the function of filtering dust and purifying the inhaled air. On the upper and rear sides, there is an arc-shaped bulge, that is, the nasal threshold, which is the interface between the skin and the mucous membrane, and also the boundary with the inherent nasal cavity. The structure of the vestibule of the nose is similar to that of the nasal skin and subcutaneous tissue, so it is also a bloated area, and the pain is also severe when bloated occurs.

Enlargement of anterior and inferior nasal cavity. The upper part is delimited by the nasal threshold and the inherent nasal cavity; the inner part is covered with skin and has rich nose hairs, which functions to filter the dust in the air. Here the skin is tightly connected to the perichondrium, and pain is more severe when bloating occurs.

The wider part of the inner surface of the wing before and below the nasal cavity starts at the nostril and ends at the nasal area. The nasal vestibule is covered with skin and has nasal hairs to filter and purify the air. The nasal vestibule is rich in sebaceous glands and sweat glands, and is one of the bulging areas. Because the skin here is directly connected to the perichondrium, bloating occurs, which is more painful.

Nasal vestibular nasal vestibitis

Nasal vestibitis refers to diffuse inflammation of the skin of the nasal vestibule.

[Diagnosis points]

(1) Inflammation of the skin of the vestibular part of the nose, which often occurs simultaneously on both sides. Mostly caused by nasal secretions.

(2) Dryness, itching, burning, and headache in the vestibular part of the nose, which may be accompanied by bleeding, and the symptoms worsen when secondary infections occur.

(3) The skin of the nasal vestibule is red and swollen, often with superficial erosion, cleft palate, nasal hair loss, and dryness. In severe cases, the anterior nostril can block the breathing and can invade the nose and upper lip.

treatment

(1) For patients with acute nasal vestibular inflammation, apply local compresses or infrared therapy, and apply erythromycin, chlortetracycline, or neomycin ointment to promote inflammation subsidence.

(2) Those with chronic inflammation can be scrubbed with 3% hydrogen peroxide to remove dryness.

(3) Apply 5% to 10% silver nitrate solution to the skin erosion and clefts, and apply nasal ointment or 5% Bai Jiangmei ointment or other antibiotic ointment.

prevention

Do a good job of health promotion work, actively treat sinus disease, thoroughly remove irritating secretions, and avoid digging your own nose to prevent the disease.

Nasal vestibular cyst

[Overview]

Nasal vestibular cysts occur subcutaneously at the base of the nasal vestibule, outside the piriform foramen, and in the soft tissues of the alveolar process of the maxilla. Middle-aged women are more susceptible, and the age of onset is mostly 30-50 years.

[Clinical manifestations]

(1) Those with enlarged cysts may have blocked nasal breathing on the same side, swelling in the nose or upper lip, and those with larger cysts may make the nasolabial folds disappear.

(2) One side of the nose attachment or the front of the pear-shaped hole bulges, touching an elastic and soft mass.

(3) Complicated infections cause a rapid increase in cysts, radiation pain in the maxilla, forehead, and orbit, and may be accompanied by a blocked nasal side.

[Physical examination]

Put one finger on the vestibule of the mouth and the other on the vestibule of the nose. You can feel the soft, elastic, wavy, removable, painless hemispherical cystic mass, and tenderness if there is infection .

[Auxiliary inspection]

1. The puncture can extract transparent, translucent or turbid honey-like liquid, most of which have no cholesterol crystals.

2. On the plain film of X-ray film, there is a light and even localized shadow at the bottom of the pear-shaped hole, without bone and lesions. Intracystic imaging can show the size, shape, and location of the cyst.

diagnosis

(A) diagnosis points

(1) One side of nasal congestion, local swelling.

(2) The semicircular bulge at the base of the nasal vestibule or the attachment of the wing, the elasticity and fluctuation of the touch.

(3) A pale yellow transparent liquid was punctured locally, and became purulent when infected.

(4) X-ray film shows uniform circular shadows at the bottom and bottom of the pear-shaped hole.

(Two) differential diagnosis

The odontogenic cysts of the nose must be identified. The cysts are usually caused by malformations or deep caries. They occur in the maxillary bone or the maxillary sinus, or the roots of the maxillary teeth. Examination shows cheek bulges, missing teeth or caries The sac fluid is ginger, sauce-colored, black or tan, and contains cholesterol crystals. The X-ray film shows that the bottom wall of the maxillary sinus can be moved, the bone is absorbed and destroyed, and the sac can contain teeth.

treatment

The cyst was completely removed by surgery.

1. Do an X-ray of the sinuses before the operation to understand the relationship between the cyst and surrounding tissues in order to determine the surgical plan. If it is a dental cyst, it is advisable to consult a dental department.

2. Surgical methods

(1) Incision: Make a horizontal incision about 1 cm near the nasal vestibule in the sulcus of the lip and gum, and its length depends on the size of the cyst.

(2) Peeling the cyst: After the mucosa is cut, the cyst is separated layer by layer along the cyst wall, and it is completely removed after being fully exposed.

(3) Treatment of the surgical cavity: After the cyst is removed, the mucosa of the nasal floor can be cut open to communicate with the surgical cavity to facilitate drainage and wound healing. If the surgical cavity is large and communicates with the maxillary sinus, a pair of holes can be formed outside the lower nasal passage to communicate with the nasal cavity as appropriate.

(4) After the hemostasis is blocked, the wound on the lips and gums is sutured.

(5) The intranasal obstruction was withdrawn 1 to 2 days after surgery; the suture was removed after 5 to 7 days.
