Introduction

Nasal reconstruction is one of the most sophisticated and delicate plastic surgery aimed at improving respiratory function and nasal aesthetic function.. This procedure is usually in cases of congenital defects, trauma, complications of previous surgeries (Like unsuccessful rhinoplasty) Or destructive diseases (Like granulomatosis) Done. Since the nose has a complex and complex structural nose, its reconstruction requires the use of suitable transplanted materials to rebuild the skeletal framework.. In this article from the site of Dr. Behnam Khorrami (Isfahan nose surgeon _ Jaw surgeon of Isfahan), To check the use of cartilage (Of the nose blade, ear or ribs) And bone (Of the skull or pelvis) We discusrate in rebuilding nasal structure.

Anatomy of the nasal structure

The nose consists of three main parts:

• Bone section: Included.
• The cartilage section: Includes lateral cartilage, septum (Septum) And the cartilage of Alar (Nose wings).
• Softening: Includes skin and subcutaneous tissues that cover the entire nasal structure.

Nose regeneration usually on the skeletal framework (Cretishing and bone) Focuses because these sections are responsible for supporting the shape and function of the nose.

Reasons for the need for nose reconstruction

1. birth defect

Choanal atresia

Cleft lip and palate (Harelip)

Cretishing anomals

2. Trauma and damage

Nasal bone fracture

Damage to Septum And lateral cartilage

3. Previous surgery complications

Nasal deformity after rhinoplasty

Excessive rhinoplasty (Over-Resection)

4. Autoimmune infection

Granulomatosis

Syphilis

Emotion

5. Malignancy

Cobalt cell carcinoma

Melanom

Cartilage and bone sources for nose regeneration

1. Rather, it is enlarging the nose by creating a bridge over the nose

Cartilage due to high flexibility and resistance to re -absorption (Resorption) Used as the main substance in nose reconstruction. The main sources of cartilage bonding are:

(A)) Nasal blade cartilage (سپتوم)

The best option for regeneration, because of the proper strength and shape

Good molding capability

Limited risk for re -absorption

Limit: In the event of previous surgeries, there may not be sufficient tissue

(B)) Ear cartilage (Ear Conkai)

Because of high flexibility and easy access

Suitable for rebuilding nose and delicate structures

Limit: Has less strength than septum cartilage

ج) Gear cartilage

The most powerful and strongest option

Suitable for rebuilding a large framework or in case of severe destruction

Limitations:

Possibility of torsion (Warpage)

Surgical incision in the gear area may cause pain and discomfort

2. Bone grafting

Bone in cases where the need to rebuild the hard structure (Such as bone nose) There is, it is used. The main sources of bone transplantation are:

(A)) Skull bone (Caloria)

Flat and strong structure

High resistance to absorption

Limit: Need complex surgical technique to harvest

(B)) Pelvic bone (Elim)

Bone marrow

High strength and adaptation to the nasal structure

Limit: The possibility of pain and discomfort after harvest

Reconstruction surgery techniques

1. Reconstruction of nasal septum

Use of septum cartilage to repair deviation or defect

If septum cartilage is not available, ear or gear cartilage is used

2. Reconstruction of the Alar structure (Nose wings)

Ear or gear cartilage is commonly used to regenerate alarms

If needed to be more robust, Gear cartilage Used as a reinforcement

3. Reconstruction of the bone part of the nose

In severe fractures, the skull or pelvis is used

A combination of cartilage and bone is used to improve the shape and height of the nose bridge

4. Nasal regeneration

Ear cartilage is commonly used to regenerate the tip of the nose because of its high flexibility

In cases of further consistency, gear cartilage is selected

Challenges and problems of nose regeneration

✅ Religious cartilage torsion

The gear cartilage is prone to twist after transplantation

The use of stabilization techniques with suture or small plates is helpful

✅ Attraction (Resorption) Cartilage or bone

Nasal blade cartilage and skull bone have the least chance of absorbing

Ear cartilage and ribs are more prone to absorbing

✅ Not comparing

Need for accurate molding of bonds

Precision stabilization and symmetry techniques

Conclusion

Nasal reconstruction using cartilage and bone transplantation is an effective and advanced way to correct nasal structural defects.. The selection of transplantation depends on several factors, including defects, surgical history, and the need for strength or flexibility.. Septom cartilage is the first choice due to its high strength and compatibility. In the absence of septum cartilage, ear or rib cartilage, and in cases of larger defects, bone transplants from the skull or pelvis are good options..
