The lateral nasal cartilage (upper lateral cartilage, lateral process of septal nasal cartilage) is situated below the inferior margin of the nasal bone, and is flattened, and triangular in shape.
The lateral nasal cartilage is a wing-like expansion extending out from the septal nasal cartilage. [5] The lateral nasal cartilage lies inferiorly to the nasal bones while sitting superiorly to the major alar cartilage, separated by a narrow fissure. The lateral nasal cartilage and major alar cartilage curl up upon interaction with one another ...
Lateral nasal defects are usually closed with an ipsilateral paramedian forehead flap. Central nasal defects can be reconstructed using either a right- or left-sided forehead flap. The ipsilateral pedicle is closer to the defect than the contralateral pedicle, therefore the flap can be made shorter when using the ipsilateral side.
Nasal defects involving either the bone or the cartilage of the lateral nose are best managed with free grafts of flat septal bone and of cartilage. Small defects of the nasal dorsum can be covered with cartilage grafts harvested from either the septum or the concha of the ear. The correction of large-area defects of the nasal dorsum requires ...
Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
The ala of the nose (ala nasi, "wing of the nose"; plural alae) is the lower lateral surface of the external nose, shaped by the alar cartilage and covered in dense connective tissue. [1] The alae flare out to form a rounded eminence around the nostril. [17] Sexual dimorphism is evident in the larger nose of the male.
The major alar cartilage (greater alar cartilage) (lower lateral cartilage) is a thin, flexible plate, situated immediately below the lateral nasal cartilage, and bent upon itself in such a manner as to form the medial wall and lateral wall of the nostril of its own side.
Nasal septum perforation due to the bilateral trauma of the mucoperichondrial flaps opposite each other. Septal hematoma and septal abscess. Adhesions and synechiae between septal mucosa and lateral nasal wall. Saddle nose due to over-resection of the dorsal wall of the septal cartilage. Dropped nasal tip due to resection of the caudal margin.
