• Environmental factors such as mouth breathing can significantly alter dentofacial and craniofacial development, including nasal morphology.
• Pediatric septorhinoplasty requires careful timing because surgery on the growing nose can affect subsequent development.
• Cleft lip and palate are strongly associated with abnormal nasal development, and comprehensive cleft rhinoplasty must account for ongoing growth.
• The nasal cavity is a primary site of Staphylococcus aureus carriage, linking nose development to infection risk and microbiome research.
• Single-cell atlases of the human airways provide a reference for understanding cellular diversity in the nasal and respiratory epithelium.
Description
Nose development (GO:0043584) is the biological process whose specific outcome is the progression of the nose over time, from its formation to the mature structure. The nose is the specialized structure of the face that serves as the organ of the sense of smell and as part of the respiratory system, and it includes both the nasi externus (external nose) and the cavitas nasi (nasal cavity). Understanding this process is fundamental for researchers in craniofacial biology, otolaryngology, and developmental genetics because the nose is a central component of facial identity and respiratory function. The nose undergoes significant growth and remodeling throughout childhood and adolescence, with distinct growth spurts that influence facial proportions. Three-dimensional studies have shown that nasal growth is not linear and that different nasal dimensions mature at different rates. Environmental factors, such as mouth breathing, can alter the trajectory of dentofacial and craniofacial development, highlighting the interplay between genetics and external stimuli. Clinically, disruptions in nose development are associated with congenital anomalies such as cleft lip and palate, and with acquired deformities that require surgical correction. Pediatric septorhinoplasty must be carefully timed to avoid interfering with ongoing growth. Additionally, the nasal cavity is a major reservoir for Staphylococcus aureus, and its anatomical development influences carriage patterns and infection risk. Recent single-cell atlases of the human airways have begun to define the cellular composition of the nasal epithelium, providing a foundation for studying nose development at unprecedented resolution.

What Is GO:0043584?
GO:0043584 (nose development) is defined as the process whose specific outcome is the progression of the nose over time, from its formation to the mature structure. The nose is the specialized structure of the face that serves as the organ of the sense of smell and as part of the respiratory system. This process includes the development of both the nasi externus (external nose) and the cavitas nasi (nasal cavity). The synonym nasus development is also used.
Why Is nose development Important in Cell Biology?
Nose development is critical because the nose is both a sensory organ and a respiratory passage, and its proper formation is essential for breathing, olfaction, and facial aesthetics. Disruptions in this process can lead to congenital anomalies such as cleft lip and palate, which require complex surgical management that must account for ongoing growth. Understanding the timeline of nasal growth is also essential for pediatric septorhinoplasty, as operating on a growing nose can have lasting consequences. Moreover, environmental factors like mouth breathing can alter craniofacial development, underscoring the need to study nose development in a broader physiological context. Finally, the nasal cavity is a primary site of Staphylococcus aureus colonization, and its developmental anatomy influences infection risk and microbiome composition.

What Happens During nose development?
Embryonic formation of the nasal placodes
In simple terms: The nose starts as two small patches of tissue on the face of the embryo.
During early embryogenesis, the nasal placodes form and invaginate to create the nasal pits, which will become the nasal cavities. This initial step is part of the broader process of nose development (GO:0043584) and sets the stage for subsequent growth and differentiation.
Growth of the external nose and nasal cavity
In simple terms: The nose grows in size and changes shape as a child gets older.
The external nose and nasal cavity undergo continuous growth from infancy through adolescence. Three-dimensional studies have shown that nasal dimensions increase at different rates, with some parameters reaching adult size earlier than others. This growth is influenced by genetic and environmental factors, including breathing patterns.
Influence of breathing mode on craniofacial development
In simple terms: How a child breathes can affect how their face and nose grow.
Mouth breathing, often due to nasal obstruction, can lead to altered dentofacial and craniofacial development compared to nasal breathing. Studies in orthodontic patients have demonstrated measurable differences in facial morphology, highlighting the importance of nasal airway function during growth.
Clinical considerations in pediatric septorhinoplasty
In simple terms: Surgeons must be careful when operating on a child's nose because it is still growing.
Pediatric septorhinoplasty is performed to correct nasal obstruction or deformity, but the timing must consider ongoing nasal growth. Surgical intervention can potentially disrupt growth centers, so careful assessment and delayed surgery are often recommended until growth is nearly complete.
Cleft rhinoplasty and long-term nasal development
In simple terms: Children born with a cleft lip or palate often need nose surgery that must adapt as they grow.
Cleft lip and palate are associated with nasal deformities that require comprehensive rhinoplasty. Because the nose continues to develop, surgical plans must account for future growth, often involving multiple stages from childhood to adulthood.

How Is nose development Regulated?
Nose development is regulated by a complex network of transcription factors, signaling pathways, and environmental influences. Key pathways include SHH, FGF, BMP, and WNT signaling, which pattern the facial primordia and control outgrowth of the nasal processes. Growth factors such as FGF8 and BMP4 regulate proliferation and differentiation of nasal mesenchymal cells. Hormonal factors during puberty also influence nasal growth, contributing to the adolescent growth spurt. Environmental factors, particularly mode of breathing, can modulate craniofacial growth trajectories. Additionally, surgical interventions must consider the regulatory role of growth centers in the nasal septum and synchondroses.
nose development and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| IRF6 | Van der Woude syndrome, cleft lip/palate | Knockout mouse, patient-derived iPSCs |
| MSX1 | Cleft lip/palate, tooth agenesis | Knockout mouse, zebrafish |
| TBX22 | X-linked cleft palate | Knockout mouse, cell models |
| CHD7 | CHARGE syndrome with choanal atresia | Knockout mouse, iPSC-derived nasal epithelium |
| FGFR2 | Craniosynostosis syndromes with nasal anomalies | Point-mutation knock-in mouse |
Cleft lip and palate
Cleft lip and palate are among the most common congenital craniofacial anomalies and frequently involve nasal deformities. The development of the nose is disrupted, leading to asymmetry, nasal tip deformities, and airway issues. Comprehensive cleft rhinoplasty is often required, with timing adjusted to the patient's growth.
Nasal obstruction and mouth breathing
Chronic nasal obstruction can lead to mouth breathing, which in turn affects dentofacial and craniofacial development. Studies have shown that mouth-breathing children may develop long-face syndrome, narrow maxilla, and altered nasal morphology compared to nasal breathers.
Pediatric septorhinoplasty complications
Surgery on the growing nose can potentially impair nasal development, leading to growth retardation or asymmetry. Therefore, pediatric septorhinoplasty is typically delayed until growth is nearly complete, except in cases of severe obstruction.
Staphylococcus aureus nasal carriage
The nasal cavity is a primary site of S. aureus colonization, and anatomical factors related to nose development may influence carriage. This has implications for infection control and vaccine development.
