Facial Plastic and Reconstructive Surgery Practice Questions

Q: Reduction rhinoplasty is done for

Hump nose. ***Hump nose*** - **Reduction rhinoplasty** aims to decrease the size of specific nasal structures, making it the appropriate procedure for a **hump nose** where the dorsal hump needs to be reduced. - This involves removing excess bone and cartilage to achieve a smoother, straighter nasal profile. *Saddle nose* - **Saddle nose** is characterized by a depressed nasal dorsum and requires **augmentation rhinoplasty** to build up the bridge, often using grafts, rather than reduction. - The goal is to add tissue, not remove it, to correct the concavity. *Crooked nose* - A **crooked nose** involves deviation of the nasal pyramid and septum, requiring a septorhinoplasty or reconstructive techniques to straighten the nose, which is a complex reshaping process, not just reduction. - The focus is on realigning structures rather than simply making them smaller. *Narrow nose* - A **narrow nose** typically requires **augmentation or spreader grafts** to widen the nasal passages or define the dorsum, which would involve adding tissue, not removing it. - Reduction rhinoplasty would further narrow the nose, which is counterproductive for this condition.

Q: At what age, in years, is rhinoplasty usually done once the nose is fully grown?

16 years. ***16 years*** - Rhinoplasty is typically performed once the **nose is fully grown**, which generally occurs in the mid to late teen years, around **15-16 years old for girls** and slightly later for boys. - Performing the surgery earlier risks altering nasal structures that are still developing, potentially leading to undesired aesthetic and functional outcomes as the nose continues to grow. *6 years* - At this age, the nose is still in its **early developmental stages** and is far from being fully grown. - Performing rhinoplasty at this age would likely disrupt normal nasal growth and lead to **severe deformities** as the child matures. *12 years* - While closer to maturity than 6 years, the nose is still undergoing significant development, especially in **boys**. - Surgical intervention at this age could still interfere with the **natural growth trajectory** of the nose, leading to suboptimal results. *25 years* - By this age, the nose has been fully grown for several years, and while rhinoplasty can certainly be done, it is not the typical age limit for when the nose is "fully grown." - This age is well past the point where growth concerns dictate the timing of the surgery; rather, patient desire and cosmetic concerns would be the primary drivers.

Q: Normal nasofrontal angle is:

125. Normal nasofrontal angle is: ***125*** - The **nasofrontal angle** is a key anthropometric measurement in facial aesthetics, particularly important in **rhinoplasty** and craniofacial analysis. - The normal nasofrontal angle ranges from **115-130 degrees**, with **120-125 degrees** considered the average ideal. - An angle of **125 degrees** falls well within this normal range and represents a **harmonious transition** from the forehead to the nasal bridge. - This angle provides a natural-appearing nasofrontal depression (sellion) and is aesthetically balanced for most facial profiles. *105* - An angle of **105 degrees** is significantly **below the normal range** (115-130°) and would be considered acute. - This could indicate a **deep sellion** or overly projected brow, potentially creating a "ski-slope" appearance or **concave nasal profile**. - Such an acute angle may result in an aesthetically less favorable appearance with excessive nasofrontal depression. *134* - An angle of **134 degrees** is **above the normal range** and would be considered obtuse. - This would create a **flatter transition** from forehead to nose with minimal nasofrontal depression. - While not as extreme as 190°, this angle exceeds the typical ideal range and may appear as an overly straight or convex profile. *190* - An angle of **190 degrees** is anatomically extreme and represents a nearly **flat or obtuse transition** from forehead to nose. - This would indicate virtually **no nasofrontal depression**, which is aesthetically undesirable and not within normal anatomical variations. - Such an extreme angle is rarely seen and would represent significant deviation from normal facial proportions.

Q: Which of the following is not a clinical feature of a fracture of the zygomatic bone?

Cerebrospinal fluid (CSF) rhinorrhea. ***Cerebrospinal fluid (CSF) rhinorrhea*** - **CSF rhinorrhea** is strongly associated with fractures involving the **cribriform plate** or **anterior cranial fossa**, typically seen in more extensive craniofacial trauma. - While a zygomatic bone fracture can cause periorbital edema and ecchymosis, it does not directly involve structures that would lead to CSF leakage. *Diplopia* - Zygomatic bone fractures can displace the eye globe or entrap extraocular muscles, leading to **double vision** (diplopia). - This is a common finding, especially when the fracture extends into the orbit. *Trismus* - The zygoma forms part of the **zygomatic arch**, which is closely related to the temporomandibular joint (TMJ) and muscles of mastication. - Fractures in this area can cause pain and muscle spasm, limiting jaw movement and resulting in **trismus**. *Bleeding* - Any bone fracture, including that of the zygoma, involves disruption of blood vessels within the bone and surrounding soft tissues. - This typically results in **hematoma formation**, swelling, and bruising (ecchymosis) around the fracture site.

Q: Which of the following statements about maxillary fractures is false?

Pediatric maxillary fracture is more comminuted. **Pediatric maxillary fracture is more comminuted** - Pediatric bones, including the maxilla, are generally more *elastic* and less brittle than adult bones, leading to *greenstick fractures* or less comminution, rather than more. - The presence of *developing tooth buds* also influences fracture patterns, making them less prone to extensive fragmentation. *Geriatric maxillary fracture is difficult to treat* - *Osteoporosis* and reduced bone density in geriatric patients can make plate fixation challenging due to poor screw purchase. - Slower healing rates and increased comorbidities in older patients can complicate surgical management and recovery. *Midpalatal fracture has 8% incidence* - This statement refers to a specific incidence rate for midpalatal fractures, which is a *correct factual statement* in the context of patterns of maxillary trauma. - Identifying specific incidence rates helps in understanding the epidemiology and typical presentations of maxillary injuries. *All four maxillary buttresses are rarely fractured together* - The maxilla is supported by four pairs of buttresses (*nasomaxillary, zygomaticomaxillary, pterygomaxillary, and vertical*) that dissipate forces. - It is uncommon for all four buttresses to be simultaneously fractured in a single traumatic event, as specific impact forces usually target certain areas.
