INTRODUCTION. The nasal vestibular body is a recently reported dynamic elevation in the vicinity of the inferolateral internal nasal valve. The contribution of this anatomical zone in persistent nasal obstruction is not yet defined.
OBJECTIVE. To assess the correlation between the tomographic size of the nasal vestibular body and the presence of na...

Context 1
... NVB arises from the infero-lateral edge of the nose, between the vestibule and the region of the internal nasal valve, and it is adjacent to the anterior part of the inferior turbinate ( Figure 1). Therefore, it is reasonable that the nasal vestibular body may be a component in the nasal obstruction experienced by some patients 1 . ...
Context 2
... the implication of this anatomical area in a decrease in nasal airflow is not recognized, it may compromise the results of standard surgical interventions for nasal obstruction. It is very important not to confuse the NVB with the nasal septal body which is a different structure, located in the anterior part of the nasal septum, adjacent to the anterior part of the middle turbinate and to the upper part of the lower turbinate 10,11 (Figure 1). ...

... In 2020, Ibrahim et al. described the participation of the NVB in nasal obstruction by comparing 18 patients with surgical reduction of the NVB against 10 patients with other nasal surgical interventions without reduction of the NVB, with improvement in the "SNOT 22" and "nasal breathing" scores in the first group [1]. In 2022, it was published by Vargas-Cárdenas et al. that computed axial tomography measurement of the NVB could correlate with symptoms of nasal obstruction [10]. ...
... With computed axial tomography, it is possible to demonstrate NVB (Figure 3). Its measurement by this imaging method may be possible, in addition to finding a relationship with the size and symptoms of nasal obstruction [10]. In this study, we did not measure the NVB by this imaging method. ...
... With this background, it will be possible to carry out intervention studies with larger populations than existing studies. Some techniques include tissue reduction [6], which can be achieved by radiofrequency ablation [10]. ...
Background and aim
Nasal obstruction is one of the most common reasons for consultation addressed by otolaryngologists. There are anatomical, physiological, and pathological etiologies. Sometimes the treatment can become a challenge for the specialist, so a detailed evaluation of the etiologies must be carried out.
The involvement of the nasal vestibular body (NVB) in obstructive symptoms has been described. Therefore, we must be familiar with its anatomy, presentation, and contribution to this symptomatology. This study aimed to highlight the importance of NVB in the role of nasal obstruction and know the impact that it adds to the symptoms of patients through a validated instrument on their quality of life.
Material and methods
A retrospective, descriptive, and analytical study was conducted on 113 patients with nasal obstruction who attended the outpatient clinic of the Otolaryngology and Head and Neck Surgery Service in a tertiary-level hospital in Monterrey, Mexico from January 2021 to January 2023. The Nasal Obstruction Symptom Evaluation (NOSE) scale was applied to assess the impact of this symptom on the quality of life of the subjects.
The causes involved in the obstructive symptoms were identified by physical examination, including NVB. Two groups were made as follows: with the presence of the NVB and with the absence of the NVB, and the means of the NOSE scale were compared.
Results
A total of 113 patients were included, 59 male patients (52.20%) and 54 female patients (47.80%). The presence of NBV was found in 72 patients (63.70%). Other causes of nasal obstruction were found in 35 patients (31%), with chronic rhinitis being the most frequent in 27 subjects (23.90%). The mean NOSE scale score was higher in the group with the presence of the NVB than in the group with the absence of the NVB (p<0.05). The primary outcome of this study was to know the prevalence of NVB in the Hispanic population with nasal obstruction who attends the otolaryngology clinic. The secondary outcome was to know the relationship between the presence of NVB and the NOSE scores.
Conclusion
In this study, we observed that NVB is frequently present in patients with nasal obstruction in northeastern Mexico. There is an association between the presence of NVB and higher scores on the NOSE scale. New research will be needed to assess the effectiveness of NVB surgery in improving nasal obstruction and to determine the impact of NVB on nasal obstruction in isolation.
