Nasal septal hematoma should also be actively assessed. It should be noted that cartilaginous injuries cannot be detected radiologically and that imaging of simple nasal bone fractures often adds little to patient management.

However, imaging can be useful in the documentation, assessing the extent and associated facial fractures and/or complications 5. Plain radiograph CT Treatment depends on the degree of displacement.

If the displacement is significant then if untreated they may result both in an unfavorable cosmetic result and in impaired function (i.e. difficulty in breathing through one or both nasal passages). Untreated nasal fractures account for a high percentage of rhinoplasty and septoplasty procedures.

A new approach to the treatment of nasal bone fracture : radiologic classification of nasal bone fractures and its clinical application. Back HE, Kim DW, BYU JR et-al.

The CT scan clearly showed nasal bone fracture with displacement of the nose. In addition to the obvious cosmetic deformity of the nose, untreated nasal fractures can also lead to functional issues.

However, if diagnosed early and treated within the first 2 weeks of injury, it is highly possible to avoid extensive surgery, functional changes, and disfigurement. One of the best methods to diagnose a broken nose is to obtain radiographic imaging.

A CT scan can also aid in surgical planning of both early treatment and, if necessary, more extensive surgery. The recovery time from a closed nasal reduction is only a few days and most patient’s can go back to full activity within a week.

After this procedure it is important to not put any pressure on the nose for 2 months while the bones heal in place. Normal sport activity can be resumed within a week with the aid of a specialized mask that protects the nose and keeps the bones in place.

To further complicate the matter, edema can mask underlying nasal deformity, crepitation, and instability; thus, many physicians and patients fail to pursue further diagnosis and appropriate treatment. If radiographic evaluation is warranted, it is best used when other facial fractures are suspected in combination with a nasal fracture, because isolated nasal fractures are treated on the basis of the physical examination alone.

The fact that patients may have displaced nasal fractures and normal-appearing plain radiographic findings should be emphasized. It should be noted that plain radiographs only serve to confuse the clinical picture in most cases.

Plain radiographs do not allow identification of cartilaginous disruptions, fractures, shearing, and injury in general. Plain radiographs also do not provide sufficient information to assess injury severity and displacement, 2 important aspects essential to emergent and delayed management and surgical planning.

A good physical examination of the internal and external nose is still the method of choice for detecting and assessing nasal fractures. Modern multi detector CT scanners have revolutionized trauma imaging and provide a fast, safe, cost-effective, and sensitive means for assessing trauma of the bone and soft tissues.

Three-dimensional reconstructions are easily derived from these scanners and readily show the degree of displacement if substantial trauma exists. Ultrasonography may be able to detect local and superficial fractures, but it can be difficult to see the entire nasal bane and neighboring bones with ultrasound.

If untreated, nasal fractures can result in unfavorable appearance and function, especially when the underlying structural integrity of bone and cartilage is lost. Untreated nasal fractures account for the high percentage of rhinoplasty and septoplasty procedures performed months to years after the initial trauma occurs.

Thus, appropriate treatment is best rendered in a timely manner, before scarring and soft tissue changes occur. As always, thorough history taking and physical examination should precede radiographic evaluation.

Nasal fracture and displacement without septal fracture usually occur with weaker applied forces; however, with increased force, displacement of the bilateral nasal bones may be noted, and the septum is usually dislocated and fractured as well. Approximately 80% of fractures occur at the lower one third to one half of the nasal bones.

This area represents a transition zone between the thicker proximal and thinner distal segments. In the US, approximately 50,000 people experience nasal fractures each year.

Nasal fractures account for approximately 40% of all bone injuries. Fights and sports injuries are the most common causes of nasal fractures in adults, followed by falls and vehicle crashes.

Play and sports account for the majority of nasal fractures in children. Physical abuse should be considered when evaluating children and women with nasal fractures.

The nose is the most prominent and anterior facial feature; as such, it is also the most readily exposed to trauma. The nose is supported by cartilage on the dorsum and caudal aspects and by bone posteriorly and superiorly.

Overlying the framework of the nose are soft tissues, including muscles, nerves, and mucous glands. The lower two thirds of the nose houses 2 upper lateral cartilages, which originate from underneath the inferior aspect of the nasal bones and project into the scroll region of the nose just superior to the nasal tip.

The paired upper lateral cartilages are continuous with the dorsal nasal septum. The septum has a dorsal, caudal, posterior, and maxillary attachment as its components and is often referred to as the quadrangular cartilage.

The medial court attach to the septum with adhesive ligaments at the caudal septum, giving structural support to the nasal tip, which is composed of the transition between the intermediate and lateral court. The use of plain images and computed tomography (CT) scans for the diagnosis and management of nasal fractures has been controversial.

Several small studies have shown that use of these modalities is neither cost-effective nor beneficial to the patient or physician. Nasal fractures are usually evident and can be elicited by means of careful history taking and physical examination.

However, some clinicians still use plain images and CT scans, and the radiologist must understand some diagnostic pitfalls to reduce the rate of erroneous readings. The practice of ordering unnecessary radiographs encourages poor patient care and devalues the importance of thorough history taking and physical examination.

This practice also leads to needless irradiation, expense, and wasted time. The accuracy rates for HORUS, CT, and conventional radiography were 100%, 92.1%, and 78.6%, respectively.

Compared with HORUS, CT revealed only 196 of 233 lateral nasal bone fractures. De Lacey et al. concluded in a study that a lateral plain radiographic view was unreliable for the evaluation of nasal fractures because of the high incidence of similar defects found in noses from control subjects and in patients with dry skulls, when evaluated using plain radiography.

In their study, the investigators evaluated 100 consecutive patients presenting to the emergency department with a history of trauma to the nose. Nasal radiographs were obtained in each patient, including the Waters and lateral views.

The authors then compared the lateral radiographs in 50 control subjects and 50 persons with dry skulls. After close inspection, the misreads were found to be the result of the midline nasal suture, the nasomaxillary suture (low defect), and thinning of the nasal wall (high defect).

The authors prospectively evaluated 54 patients clinically, radiologically, and under anesthesia within 19 days after nasal injury. External examination and nasal rhinos copy were performed to evaluate the patients clinically.

When evaluation of children is necessary and one wishes to limit exposure to radiation, ultrasonography has been helpful to some in evaluating nasal fractures, septal deviation, and level of combination. In the utilization of 3-dimensional (3D) CT scanning for facial and nasal fractures, better evaluation scores were achieved with surface rendering protocols than with volume rendering protocols.

Thus, the legal value is low because of the uncertain degree of confidence in the findings. Radiographic examinations of the nose have been known to fail in the assessment of nasal fractures.

Features of the Waters and lateral radiographic views of nasal fractures are discussed in this section. The radiograph is obtained in the posteroanterior position, with the canthomeatal line at an angle of approximately 37° relative to the surface of the film (see the image below).

The patient's dentures and oral prosthetic devices, if any, should be removed, because these structures may cause interference. Posteroanterior view shows displaced septum from the maxillary crest and a deviated nasal root to the patient's right.

The Waters view demonstrates the orbits, maxillae, zygotic arches, dorsal pyramid, lateral nasal walls, and septum (see the images below). The radiologist should look for abnormalities of the nasal septum and arch, keeping in mind the areas of relative weakness.

Marked deviation, displacement with sharp angulation, and soft-tissue swelling are signs of possible fracture. Other structures, such as the frontal, maxillary, and ethmoid sinuses, may also be involved.

Any such involvement should alert the physician to the possibility of concomitant fractures. Waters view (close-up view of the patient in the previous image) shows a deviated nasal septum, quadrangular cartilage displaced from the maxillary crest, and a nasal root deviated to the right.

This orientation provides a true lateral projection that is neither tilted nor rotated; therefore, paired structures are superimposed. Many prefer to include the full profile from the forehead to the chin with a technique that uses a Bucky grid (see the images below).

The lateral view obtained by using a soft-tissue technique is probably best for depicting old and new fractures of the nasal bones. The profilogram provides no information regarding a possible laterally displaced nasal bone.

Short, recent lines that reach the anterior cortex of the nasal bone, with or without displacement, should be regarded as a fracture. Alterations of air-zone shapes may indicate cartilage volume increases or septal hematoma.

However, a nasociliary groove should never cross the plane of the nasal bridge; if this is demonstrated, the line is a fracture. Fortunately, fractures usually demonstrate a sharpened delineation, with greater lucency than normal sutures and grooves.

The radiologist must look closely for marked deviation, displacement with sharp angulation, and soft-tissue swelling. Radiographic findings consistent with nasal fracture may be identified in 53-90% of patients with isolated nasal fractures.

Because of this and other concerns, Logan et al. questioned the reliability of nasal bone radiographs. Similarly, a study by Hwang et al. also suggested that plain radiography is unreliable in the diagnosis of nasal bone fractures and that CT should instead be used in such diagnoses.

The investigators examined the use of plain radiography in the evaluation of 503 nasal bone fractures, using the lateral and Waters views. Logan et al. believed that the high percentage of false-negative and false-positive results with nasal bone radiographs had a number of causes.

Old fractures, vascular markings, cartilage fractures, midline nasal sutures, nasomaxillary sutures, and thinning of the nasal wall represent a few of the many features that may mislead even an experienced radiologist. De Lacey et al. conducted a similar study, which showed that 66% of control subjects had a false-positive reading using Waters view radiographs.

Unfortunately, an accurate depiction of the rate of false-positive and false-negative results from injured patients cannot be obtained by using their data. CT's scans are usually obtained when another traumatic facial or skull fracture is suspected.

Many fractures are also demonstrated on routine head CT scans in patients with trauma. Although CT scans can be used to demonstrate the extent of nasal injury, they are rarely required.

These scans are helpful when associated injuries are suspected in combination with nasal fractures. Coronal CT scan demonstrates a nasal fracture with root deviation to the right.

CT scans depict important structures, such as the orbital walls, zygotic arches, frontozygomatic sutures, maxillary buttresses, ethmoid air cells, nasal bones, dorsal pyramid, and floor of the frontal sinuses with the associated nasofrontal ducts. In one study of axial and sagittal images for nasal bone fracture, sagittal multi planar reconstruction (MPR) images were found to be more sensitive than axial images, especially for type 1simple nasal bone fractures with no displacement or minimal displacement.

Computed tomography has a higher sensitivity than ultrasonography, but a study by Lee et al. found that ultrasonography may have good specificity, positive predictive value, and negative predictive value for midline nasal fractures. Ultrasonography may be able to detect local and superficial fractures, but it can be difficult to see the entire nasal bane and neighboring bones with ultrasound.
