Nasal Fossae Dimensions in the Neonate and Young Infant

Abstract

This study defined the normal range of variation for the main dimensions of the nasal fossae in the horizontal plane. These can be used as a basis for determining nasal stenosis in cases of neonatal obstruction.

Nasal Region Dimensions in Children: A CT Study and Clinical Implications

“…Also in other studies, similar results have been obtained for that part of the nasal cavity [1]. For the RMMW and LMMW dimensions, we obtained higher values, in comparison with the values obtained by other authors [1, 4]. …”

“…In the age group of 3 to 6 months, the result was 15.600 ± 1.57 mm, and in the age group between 6 and 12 months of age was 17.110 ± 1.275 mm. Contencin et al analyzed 62 head CT images, obtained in children under 1 year of age [4]. The bone-to-bone dimensions of the pyriform aperture amounted to 13.24 ± 1.88 mm, and their value was also below the value obtained in our study, for the parameter described.…”

“…The bone-to-bone dimensions of the pyriform aperture amounted to 13.24 ± 1.88 mm, and their value was also below the value obtained in our study, for the parameter described. Both Aslan et al and Contencin et al took measurements of distances between mucous membranes in the anterior part of the nasal cavity [1, 4]. The distance measured between lateral wall mucosa, corresponding to the AMW dimension in our study, amounted, in case of the authors quoted, to 8.73 mm and 0.94 ± 0.14 cm in children under one year of age, respectively.…”

“…The research work carried out so far, devoted to the measurement of morphometric parameters of nasal cavity, and determination of reference values for that area of the facial skeleton has been carried out on groups of children and youngsters, often comprising wide age ranges. They are often wider than the age ranges applied in our study: under 6 months of age [4], under one year of age [7], or under two years of age, as in the study by Belden et al [18]. Such a manner of selecting the age group for the study, bearing in mind the size of the group, results in analyses being carried out often on small subgroups of children.…”

Midfacial growth patterns in males from newborn to 5 years old based on computed tomography

“…Pool et al () report the interorbital distance at 0–3 months to be intermediate between the values in newborns and at 1–2 months of the present study. Contencin et al () found very similar nasal and choanal breadths in newborns (0.75 mm more and 0.22 mm less than in our study, respectively). Escaravage and Dutton () provide values for the anterior medial interorbital length (≈interorbital breadth of our study) and anterior vertical orbital length (≈orbital height) expressed as a percentage of adult size attained at 0–1, 10–12, and 25–35 months of age.…”
