Injuries sports to the nose are relatively common; in cases of facial trauma, nasal fractures account for approximately 40 percent of bone injuries. (1) Fights and injuries account for greatest in quantity nasal fractures in adults, followed from falls and vehicle crashes. Play and sports account for greatest in number nasal fractures in children. Physical abuse should be considered in children and women and should be appropriately rul public (2)

Nasal fractures may be found in isolation or in association with other facial injuries. Furthermore, many nasal fractures advance undiagnosed and untreated because one patients do not seek medical care. (3) granting seen occasionally in family practice, patients with nasal fractures are more likely to at hand to emergency departments or pressing care settings. Fractures that are more than couple days old will have substantial edema and should be referr pressingly for subspecialty evaluation.

Anatomy

The nose is easily expos to trauma because it is the mostly prominent and anterior feature of the face. The nose is supported at cartilage anteriorly and inferiorly, and by way of bone posteriorly and superiorly (Figure 1) The paired nasal bone the nasal proces of the frontal bone and the maxilla form a framework to support the cartilaginous skeleton. Although chiefly of the nasal structures are cartilaginous, the nasal bone usually are fractured in an injury.

[FIGURE 1 OMITTED]

Overlying this framework are easily moulded tissues, mucous glands, muscles, and hardihoods responsible for sensation and function of the nose. on virtue of its natural taper, the supporting nasal septum becomes increasingly thin and is therefore make liable to fracture toward the tip of the nose.

The relative ease by means of which epistaxis can occur with minor trauma is explained by the agency of the dense and redundant vascular network that supplies the nose. This plexus, known as Kiesselbach's area, is responsible for the vast majority of normal epistaxis. (4) However, bleeding as a be derived of nasal fracture usually originates from other locations within the nose. For example, profuse anterior bleeding may originate from the anterior ethmoid artery (a branch of the ophthalmic artery), while posterior bleeding is more likely to arise from a branch of the sphenopalatine artery. Arterial ligation may be necessary if packing fails to regulate bleeding. In such cases, early consultation with an otolaryngologist is indicated. (56)

Assessment

HISTORY

Understanding the mechanism of trauma is helpful to the physician in determining the stretch of the injury. It is useful to know the responsible final cause the direction from which it came, and the impregnability of force sustained by the nose. For example, a direct frontal disaster can depress the dorsum of the nose, causing the fractured bone to spyglass posteriorly. Likewise, a laterally directed injury can cause a depression forward the side of the impact, many times with a corresponding outward displacement in succession the opposite side of the nose. Traction and torsion injuries, however rare, also can cause cartilaginous disruption. (7)

The patient should be asked about the timing and volume of any bleeding associated with the injury. The history also should include information regarding previous surgeries, injuries, and a subjective assessment of baseline nasal function and appearance. Finally, because alcohol use commonly is associated with such trauma, physicians may wish to determine whether the patient had been drinking before the injury. This point may have implications for selection of pain medications, potential for repeat injury, and the ability to assess for mental status changes associated with head injury.

PHYSICAL EXAMINATION

greatest in quantity nasal fractures are the inference of minor trauma such as being punched or elbowed. However, when assessing a patient with an acute nasal injury, the physician should avoid focusing solely upon the obviously traumatized nose. This is particularly important if the patient has experienced a violent traumatic fact such as a motor vehicle crash or an assault. A substantial direct bloom to the mid-face area can eventuate in cervical spine injury, and the physician must therefore exercise clinical decision in using appropriate precautions until a cervical spine injury is rul public During the initial assessment, the physician should be certain that the patient has an adequate airway and is ventilating appropriately.

A nasal injury may be associated with other head and neck trauma that could compromise the patency of the trachea. Furthermore, given the choke proximity of the nose to other facial arrangements the physician must consider the possibility of an associated facial or mandibular fracture. (3) Therefore, all bony formations of the face, including the malar eminences, orbital rims, zygomatic arches, mandible, and teeth should be carefully inspected and palpated for irregularity or tendernes All facial lacerations, swellings, and deformities should be noted, and the organ of sights should be examined for regular arrangement and mobility of gaze. (8) If a facial or mandibular fracture is suspected, radio-logic assessment with comput tomography (CT) is indicated. (9)
