3 main causes of bulbous nose | Treatment approach varies by cartilage, skin, and fat
Generally, among those seeking nose surgery, concerns about "bulbous nose" are very common. This article divides the causes of bulbous nose into 3 main types for ease of understanding, but in reality, most cases are a "mixed type" involving a combination of these factors. Rather than making hasty self-diagnoses through self-checks, please use this as knowledge to help you make appropriate treatment choices.
- 3 major causes that form a bulbous nose (Cartilage, skin, fat)
- Simple ways to identify your type
- Nose tip refinement and other "treatments expected to improve" depending on the cause
Many people worry, "Even though I've tried massage, my nose tip isn't getting narrower at all." The structure of the nose is complex, and self-care that doesn't match the cause cannot be expected to be effective. It is important to anatomically understand the condition of your own nose and consider appropriate treatment options.
Is "pinching makes it narrower" really true? Why bulbous nose causes are complicated
You may have heard the rumor that if you pinch and massage your nose tip with your fingers, a bulbous nose will be corrected. However, from a medical standpoint, it is difficult to fundamentally change the structure of the nose tip through external pressure alone.
An ideal nose tip has a general guideline where the distance between the left and right domes (the apex of the nose tip) is 2–3 mm, and the overall width (tip-defining points) is 5–9 mm.
Deviation from this narrow range of just a few millimeters makes it easy to visually perceive the nose tip as "round" or "bulbous." According to research by Chauhan et al., 41% of patients seeking initial nose surgery have "bulbous tip" as their chief complaint, indicating it is a very common concern[1].
A bulbous nose is not merely a "lump of flesh" – it is formed by the complex intertwining of cartilage, skin, and fat underneath. Therefore, appropriate treatment planning cannot be established without accurate cause analysis.
Which are you? "3 causes" that create a bulbous nose and how to tell them apart
Understanding which type your nose is closest to can be helpful in comprehending treatment options, but self-assessment is merely reference information. In many cases, the causes are complex, and the tactile sensation changes depending on past surgical history, scarring, and sebum levels, making self-diagnosis risky. For accurate diagnosis, comprehensive evaluation of cartilage strength, skin thickness, and elasticity through visual and tactile examination by a physician is essential.
Cause 1: Spreading and development of the alar cartilage (alae cartilage)
This is a type caused by the left and right cartilages called "alar cartilage" that form the shape of the nasal tip. As an example of specialized diagnostic criteria, factors such as the width between cartilage domes and the angle of divergence of the cartilage are evaluated. When these exceed certain thresholds, the nasal tip tends to become box-shaped or rounded (bulbous nose). However, since there is individual variation, detailed diagnosis requires evaluation by a specialist.
Additionally, there are reports suggesting that when the nose has such a bulbous shape, the alar cartilage tends to be positioned higher (toward the head) than where it should naturally be. When you gently pinch the nasal tip with your fingers and can relatively clearly feel the spreading of the hard cartilage itself rather than the subcutaneous soft tissue, this type is a possibility. However, this is an extremely subjective sensation, and the feeling varies greatly depending on skin thickness and fat volume, so accurate evaluation requires tactile examination by a specialist.
Cause 2: Skin thickness
Skin thickness at the nasal tip (Skin thickness) is also a major factor in bulbous nose. There is individual variation in nasal skin—thin or thick—and in the number of sebaceous glands.
When the skin itself is thick and firm, the shape of the internal cartilage does not stand out on the surface, giving an overall round and flat impression. If pinching produces the sensation of pinching a thick blanket, skin thickness may be a contributing factor.
Cause 3: Volume of subcutaneous fat and soft tissue
This type has excessive subcutaneous fat and connective tissue and other soft tissues overlying the cartilage. There are reports suggesting that Japanese people tend to have more subcutaneous fat at the nasal tip compared to Westerners, but individual variation is significant, and this abundance of fat can be a factor emphasizing roundness.
Bulbous nose caused by cartilage: Improvement approach through nasal tip plasty
This is the most common question in consultations. "Doctor, is cutting away cartilage the only way to make my nose tip slimmer?"
In fact, in modern rhinoplasty, reversible and tissue-friendly approaches such as suturing (binding with thread) and cartilage grafting are preferred over destructive approaches that excessively remove cartilage.
When the cause is due to the widening of the alar cartilage, "Nasal tip refinement (nasal tip plasty)" is one of the treatment options. Specifically, the procedure involves bringing the widened cartilage toward the center and suturing it together. According to research by Boustany et al., suture techniques that control cartilage shape are considered effective when cartilage is sutured using appropriate suture material.[2].
However, it is not simply a matter of suturing the cartilage; rather, implementing measures to ensure long-term stability is important.
If cartilage is merely brought together, forces will cause it to revert to its original shape over time. Therefore, it is important to combine multiple suturing techniques, such as suturing between the left and right domes (suturing cartilage to cartilage), to construct a beautiful diamond-shaped nasal tip that remains stable over the long term.
Bulbous nose caused by "fat and skin": Treatment options using excision and grafting
Online summary sites often say "fat removal (subcutaneous tissue excision) is effective for bulbous noses," but actual research presents different perspectives.
Especially in patients with thick skin and poor elasticity,excessive fat removal may not be recommended. For thick-skin types, an approach that not only removes fat but also provides height and strength to the tip with cartilage grafting (Tip augmentation), pushing up the thick skin from inside like a tent, can be effective. Often, combining nasal tip refinement through cartilage suturing, soft tissue adjustment, and cartilage grafting can produce more effective results.
Past research has pointed out cases where simply placing cartilage grafts beneath the skin in patients with thick skin showed no improvement in shape. In other words, creating a "robust foundation" that can withstand the pressure of thick skin is absolutely essential.
An important factor determining the result at 6 months post-procedure — it is "post-operative compression fixation." According to research by Ozucer et al., by securing the skin firmly to the internal framework through tape fixation, post-operative swelling (edema) can be reduced, and in patients with particularly thick skin, the potential to contribute to favorable results is suggested[3].
Why is "just tying with thread for now" dangerous? Important points to note in bulbous nose surgery
You may encounter advertisements claiming to "easily eliminate bulbous noses with thread tying, no downtime," but simple treatments that ignore anatomical structure carry risks.
The nasal support structure (Tip support: the support mechanism of the nasal tip) is extremely delicate. Clinical experience shows that even a simple incision between the nasal septum and columella can lower the height of the nasal tip (projection). In this way, nasal procedures can have unexpected effects on other areas from a single operation.
If a widened bulbous nose is forcibly tied up with thread alone, there is a risk of creating an unnaturally pinched nose (pinch nose), or the cartilage may buckle, making breathing difficult. For this reason, depending on the nasal structure, methods such as columellar strut (cartilage support pillar) or septal extension grafting (cartilage grafting to extend the nasal septum) may be selected to establish a cartilage support pillar and reinforce from the foundation. This allows for aesthetically stable results.

Summary of this article
- Bulbous noses are broadly divided into three types: "cartilage widening," "skin thickness," and "excess fat"
- When cartilage is the cause, "nasal tip refinement" (suturing the cartilage together) is one treatment option
- In cases of thick skin, an approach of adding height through cartilage grafting rather than just fat removal and stretching the skin can be effective
- "Simply tying with thread for now" — simple procedures carry risks of unnatural deformity or relapse, requiring caution
Treatment of bulbous noses requires accurate evaluation of anatomical features including not only the causes explained in this article but also individual cartilage strength, skin thickness, and the condition of the support mechanism, and then combining appropriate surgical techniques — this is extremely important. When considering treatment, please receive sufficient consultation at a specialized medical facility and discuss the optimal method for your condition carefully with your physician.
