“…than one-third to one-half of the total length of the nose, predisposing to middle nasal vault collapse. 14,15 In our cohort, the nasal bone-to-length ratio was 0.45, which can be regarded as short. Further studies on this aspect should be conducted in other ethnic groups to investigate the effect of nasal bone-to-length ratio on nasal valve obstruction after N95 respirator fitting.…”

Objectives To determine whether: the N95 respirator affects nasal valve patency; placement on the bony vault improves patency; and external nasal anatomy affects the outcome. Methods A prospective study with 50 participants was conducted. Nasal patency was measured by the minimal cross-sectional area via acoustic rhinometry, and using the Nasal Obstruction Symptom Evaluation survey, before and after wearing the N95 respirator and after adjustment. Results The minimal cross-sectional area was narrowed by 27 per cent when wearing the N95 respirator (p < 0.001), and improved by 9.2 per cent after adjustment (p = 0.003). The total Nasal Obstruction Symptom Evaluation score increased from 10.2 to 25.4 after donning the N95 respirator (p < 0.001), and decreased from 25.4 to 15.6 after adjustment (p < 0.001). There was no correlation with external nasal anatomy parameters. Conclusion Wearing the N95 respirator causes narrowing of the nasal valve, and adjustment onto the bony vault improves symptoms. The findings were not affected by external nasal anatomy.

“…They are joined in the midline and are connected by fibrous attachments to the upper lateral cartilages inferiorly. Measurements of average nasal bone length are around 24 mm 11,12 but vary in patients based on age and race. The thickness of the nasal bones is thickest superiorly, thinning inferiorly.…”

Corrective rhinoplasty after significant nasal trauma is a much different entity than elective rhinoplasty or rhinoplasty after minor trauma. The more significant the degree of trauma the patient is subjected to, the greater the deleterious effects will be on the soft tissue and skeletal elements of the patient's nose. With this disruption of the anatomic integrity and dynamics of the nose, the patient experiences deformity and dysfunction of the nose. This may be minor and transient or may be lifelong and disabling. In this article, the authors review some of the more long-term aspects of nasal trauma and provide the reader with insights to the use of cartilage grafting techniques that are useful in the management of posttraumatic nasal deformity and airway obstruction.

“…Anatomically, the average length of the nasal bones in adult Caucasian patients is 24.5 mm, comprising 67% of the nasal sidewall. 15 Patients with a lateral nasal sidewall comprised of a larger proportion of cartilage and shorter nasal bones appear to have a greater tendency toward collapse. 7,8 Functionally, the upper lateral cartilages contribute to the lateral portion of the internal nasal valve area of the nose that is important in the maintenance of nasal patency and serves as a modulator of nasal resistance during respiration.…”

The management of the middle vault has become a crucial consideration in esthetic and functional rhinoplasty. Central to this management is an acknowledgment of the importance of the anatomic features and functional integrity of this nasal region. The diagnosis of middle vault insufficiency and techniques to prevent and repair such collapse have been widely reported. Many of these descriptions are based on the management of the middle vault using an open rhinoplasty approach. The purpose of this article is to describe various options for the management of the middle vault using an endonasal approach that have been used by a single surgeon in a university hospital-based setting.
