The nose's prominent, central position, combined with the delicate nature of its underlying structures, renders it uniquely vulnerable to trauma. Your management begins not in the operating room, but with a meticulous patient evaluation, as the ultimate goal extends beyond simple fracture reduction to the dual restoration of the nose’s premorbid aesthetic form and its critical respiratory function. This guide provides a rigorous framework for the evaluation and management of nasal fractures, focusing on the critical decision-making between closed and open reduction. ### 1.1 Definition and Pathogenesis A nasal bone fracture is a break in the bony pyramid of the nose, accounting for up to 50% of all facial fractures. This high incidence is a direct result of the nose's anterior projection and the relative thinness of the paired nasal bones. The most common mechanism of injury is blunt force trauma, typically resulting from: - Physical altercations - Motor vehicle accidents - Sports-related injuries - Falls ### 1.2 Essential Clinical Anatomy A fundamental understanding of nasal anatomy is critical for your diagnosis and operative plan. The nose is a complex three-dimensional structure of bone and cartilage. - **Bony Pyramid:** The upper third of the nose comprises the paired, wedge-shaped nasal bones. These articulate superiorly with the nasal process of the frontal bone, laterally with the frontal process of the maxilla, and centrally with the ethmoid and vomer. - **Cartilaginous Vault:** The lower two-thirds are supported by a cartilaginous framework, including the paired upper and lower lateral cartilages and the quadrangular cartilage of the nasal septum. - **Keystone Area:** This is a structurally critical junction where the caudal edge of the nasal bones meets the cranial aspect of the upper lateral cartilages, the perpendicular plate of the ethmoid, and the cartilaginous septum. This area provides essential support to the nasal dorsum. - **Vascular Supply:** The nose receives a rich, dual blood supply from branches of both the internal and external carotid arteries. This robust vascularity explains why epistaxis, often from the Kiesselbach plexus, is an almost universal finding in nasal fractures. A thorough patient evaluation is essential to determine the extent of this anatomical disruption and to formulate an appropriate plan for reconstruction. ## 2.0 Foundational Patient Evaluation Your management of a nasal fracture begins with a comprehensive patient evaluation, combining a detailed history with a meticulous physical examination. This clinical assessment is paramount; it forms the basis of your diagnosis and frequently obviates the need for radiographic imaging. ### 2.1 Patient History When evaluating a patient with a suspected nasal fracture, gathering a precise history is the first critical step. Key points to elicit include: - The mechanism, vector, and timing of the injury. - Any pre-existing nasal deformity or history of previous nasal surgery. - A prior history of nasal breathing difficulty, obstruction, or sleep apnea to establish a functional baseline. - A premorbid photograph, such as a driver's license, which is invaluable for determining the patient's baseline nasal appearance. ### 2.2 Physical Examination The physical exam must be systematic and thorough, encompassing both external and internal assessments. - **External Examination:** You must assess for obvious deformity, lacerations, epistaxis, and any clear rhinorrhea that might suggest a cerebrospinal fluid (CSF) leak. Palpate the nasal bones gently to identify pain, step-offs, instability, or crepitus. Note the presence of periorbital ecchymoses. Remember, significant soft tissue edema can develop rapidly and mask the true extent of the underlying skeletal deformity. - **Internal Examination:** An intranasal examination is mandatory. Use a nasal speculum, an adequate light source, and a topical anesthetic with a vasoconstrictive agent to facilitate a clear view. You must carefully inspect for mucosal lacerations, septal deviation, and, most critically, the presence of a **septal hematoma**. A septal hematoma appears as a purplish, bulging mass on the septum and represents a surgical emergency that, if left untreated, can lead to cartilage necrosis and a permanent saddle nose deformity. ### 2.3 The Role of Imaging Nasal fractures are a clinical diagnosis. Treatment is based on the physical exam, not radiographs. - **Plain Films:** Standard X-rays have minimal utility. They frequently fail to identify bony injury and cannot visualize cartilaginous structures. - **Computed Tomography (CT):** A CT scan of the facial bones (with axial, coronal, and sagittal views) provides superior detail but is reserved for cases of significant maxillofacial trauma where you suspect more complex injuries, such as naso-orbital-ethmoid (NOE), orbital, or frontal bone fractures. This comprehensive diagnostic evaluation forms the basis for formulating a patient-specific treatment plan. ## 3.0 Treatment Modalities for Nasal Fractures The management of nasal fractures encompasses a spectrum of options, from nonoperative measures to surgical intervention. Your decision to operate, and the choice between a closed or open technique, is dictated entirely by the specific fracture pattern, the degree of displacement, and the overall clinical presentation. ### 3.1 Nonoperative Management Conservative management is indicated for patients with nondisplaced or minimally displaced fractures who have patent nasal airways. It is also the appropriate choice for patients who desire no surgical intervention. Treatment options include: - External splinting for protection - Elevation of the head to decrease edema - Ice application - Nasal saline irrigation ### 3.2 Closed Nasal Fracture Reduction Closed reduction is the least invasive surgical approach, involving manipulation of the fractured bones back into position without external skin incisions. Its primary goal is to restore nasal symmetry and airway patency for appropriately selected injuries. #### 3.2.1 Indications and Timing The primary indication for a closed reduction is a **simple, unilateral or bilateral, non-comminuted fracture**. The timing of your intervention is a critical factor for success: - **Immediate Reduction:** If a patient presents within the first few hours of injury, before significant edema has developed, an immediate reduction can be performed. - **Delayed Reduction:** If the patient presents more than 3-4 hours after injury, swelling will obscure the deformity. In these cases, you must defer the intervention for approximately **7–10 days** to allow the edema to resolve, enabling a more accurate reduction. #### 3.2.2 Anatomy of the Technique A closed nasal reduction follows a well-defined sequence of steps. 1. **Anesthesia:** Achieve anesthesia with a two-part technique. First, place cotton pledgets soaked in a topical anesthetic (e.g., 4% lidocaine) and a vasoconstrictor (e.g., oxymetazoline) intranasally. Second, inject a local anesthetic (e.g., 1% lidocaine with epinephrine). 2. **Bony Reduction:** Before inserting any instrument, place a Boies or Goldman elevator externally to measure the distance from the alar rim to the nasion of the medial canthus. This critical safety maneuver prevents inadvertent advancement into the cranial base. Then, insert the elevator intranasally to the predetermined depth and apply firm upward and outward pressure to the undersurface of the depressed nasal bone, using your other hand for external digital manipulation. 3. **Septal Realignment:** Reduce the nasal septum using direct, blunt pressure to the displaced portion. Alternatively, Asch or Walsham forceps may be used by placing the blades on either side of the septum to gently manipulate it back into its proper alignment in the groove of the vomer. 4. **Splinting:** After confirming a satisfactory reduction, apply an external thermoplastic splint (e.g., Denver splint) to the nasal dorsum to support and protect the fracture. #### 3.2.3 Postoperative Management - Maintain head elevation for the first 48-72 hours. - Apply ice for the first 24 hours to minimize swelling. - The external splint should remain in place for approximately 1 week, but may be left for up to 2 weeks depending on fracture severity and stability. - If internal splints are used, they are typically removed in 3-4 days. #### 3.2.4 Outcomes and Complications The goal of a closed reduction is to minimize deformity in the least invasive way. While most patients experience significant improvement, **complete correction of the deformity is unlikely** with this indirect approach. Potential complications include persistent deformity, obstructed breathing, and infection. Counseling the patient on these realities, particularly the high likelihood of a minor residual deformity, is a critical part of the informed consent process. #### 3.2.5 Clinical Pearls & Q&A for Learners ##### Key Clinical Pearls - You must always perform a thorough internal exam to identify and immediately evacuate any **septal hematoma** to prevent subsequent cartilage necrosis and saddle nose deformity. - If delaying surgery for edema, wait the full 7-10 days for optimal visualization of the deformity. - **Always measure the elevator length externally** before intranasal insertion to avoid advancing it too far and risking injury to the cribriform plate. - Allow adequate time (7-10 minutes) for topical anesthetics to take full effect to minimize bleeding. ##### Surgeon's Questions for the Learner | | | |---|---| |Question|Answer| |**Why is it critical to measure the elevator on the outside of the nose before inserting it to reduce a fracture?**|This maneuver prevents advancing the elevator too far into the nasal vault in the event of an injury to the cribriform plate, which could have severe intracranial consequences.| |**A patient presents 2 days after an assault with a nasal fracture and significant swelling. What is the optimal timing for a closed reduction?**|The operative intervention should be deferred until the edema has fully resolved, which is generally 7-10 days after the injury. This allows for full visualization of the deformity and facilitates a more accurate reduction.| |**What is the primary goal of a closed reduction, and what expectation must be set with the patient beforehand?**|The goal is to minimize the nasal deformity in the least invasive manner possible. It is important to establish the realistic expectation that a residual minor deformity is not uncommon and that a future open reduction or rhinoplasty may be an option if the outcome is unsatisfactory.| ### 3.3 Open Nasal Fracture Reduction Open reduction provides direct visualization of the fracture site through surgical incisions. This is the preferred approach for complex, severely displaced, comminuted, or delayed-presentation injuries to achieve a more precise anatomical reduction and internal fixation. #### 3.3.1 Indications The decision to proceed with an open reduction is based on the complexity and severity of the injury. Key indications include: - Severely displaced or dislocated fractures of the nasal bones or cartilaginous vault. - Comminuted (closed or open) fractures. - Fracture or dislocation of the caudal septum. - Open septal fractures. - Persistent deformity after an attempted closed reduction. - Delayed presentation (over 2 weeks since the injury). #### 3.3.2 Anatomy of the Technique: Approaches and Fixation All open approaches share common principles. You expose fractures in a subperiosteal plane, address septal deformities first (while preserving a 1-cm dorsal and caudal L strut for support), and stabilize the reduction with internal fixation using low-profile miniplates, wires, or thick absorbable sutures. - **Use of Existing Lacerations:** This opportunistic approach utilizes a pre-existing traumatic wound for access, avoiding additional incisions. - **Coronal Approach:** This approach uses an ear-to-ear incision within the hairline, providing wide exposure when other facial fractures (e.g., frontal bone) are present. - **"Open-Sky" or Glabellar Approach:** This technique uses a transverse glabellar incision and provides direct visualization of complex naso-orbital-ethmoid (NOE) fractures. - **Open Rhinoplasty Approach:** This utilizes a transcolumellar incision combined with marginal incisions. It offers maximal surgical exposure for precise work but results in an external scar and can cause prolonged nasal tip edema. #### 3.3.3 Postoperative Management - Elevate the head of the bed to minimize edema. - Apply cold compresses as tolerated for the first 24 hours. - There is a strict prohibition on **nose blowing for 4 weeks**. - Remove external splints and any permanent sutures at the 1-week visit. - Nasal saline or decongestants may be used as needed for congestion. #### 3.3.4 Outcomes and Complications Despite direct visualization, open reduction carries a surprisingly high incidence of persistent nasal deformity, with revision rates reported from **14% to 50%**. Failure to adequately address underlying septal injuries is a primary cause of long-term problems. Potential complications include persistent deformity, infection, unfavorable scarring, septal hematoma, and epistaxis. A thorough discussion of these risks is essential for informed consent. #### 3.3.5 Clinical Pearls & Q&A for Learners ##### Key Clinical Pearls - You must always address septal deformities first; consider the septum the keystone of your entire reconstruction. - When the nasal bones are mobile and displaced, use the patient's **incisors as a reliable midline reference**. - When using internal fixation, use low-profile plates. Avoid placing hardware where glasses rest on the nose to prevent potential plate exposure. - Do not strip the periosteum from small bony fragments, as this may devascularize them. ##### Surgeon's Questions for the Learner | | | |---|---| |Question|Answer| |**During an open reduction for a severely comminuted fracture, what anatomical structure serves as a stable anchor for plating?**|The intact frontal bone or maxilla should be used as a stable anchor point for plating severely comminuted and displaced nasal bone fractures.| |**What is the most critical component to address to prevent long-term deformity, and why?**|The septum is the keystone of the correction. Untreated or unrecognized septal deviation or injury is highly likely to require a future septorhinoplasty for both aesthetic and functional reasons.| |**What are the main advantages and disadvantages of using an open rhinoplasty approach for a nasal fracture?**|The main advantage is maximal surgical exposure, which allows for precise tissue handling, suturing, and grafting. The primary disadvantages are the need for a transcolumellar incision and the potential for wide dissection to cause loss of support and prolonged nasal tip edema.| ## 4.0 Comparative Summary: Closed vs. Open Reduction The choice between closed and open reduction is fundamental to your surgical management. This table provides an at-a-glance comparison to crystallize the key factors in clinical decision-making. | | | | |---|---|---| |Feature|Closed Reduction|Open Reduction| |**Key Indication**|Simple, non-comminuted, unilateral or bilateral fractures.|Complex, comminuted, severely displaced fractures; septal fractures; or failed closed reduction.| |**Primary Advantage**|Minimally invasive; no external incisions; can be performed under local anesthesia.|Direct visualization of fractures allows for precise anatomical reduction and internal fixation.| |**Primary Disadvantage**|Indirect reduction is less precise; complete correction is unlikely; not suitable for complex injuries.|More invasive; requires external incisions (except when using lacerations); risk of scarring; longer operating time.| |**Typical Outcome**|Significant improvement in symmetry, but residual minor deformity is common.|Higher potential for precise anatomical correction, but revision rates for persistent deformity remain high (14-50%).| ## 5.0 Conclusion: Key Principles in Nasal Fracture Management Successful management of nasal fractures is a cornerstone of facial trauma care. Your treatment plan must be built upon a meticulous clinical evaluation, where a detailed history and a thorough physical examination guide the selection of the most appropriate technique. While methods range from observation to complex open reduction, the ultimate objectives are constant: restore the patient's premorbid nasal aesthetics and preserve or improve nasal airway function. A clear understanding of the indications, techniques, and limitations of both closed and open reduction is essential to achieving these goals and optimizing patient outcomes.
