Abstract

PEREIRA, Suelen Cristina da Costa; BELTRAO, Rejane Targino Soares; JANSON, Guilherme  and  GARIB, Daniela Gamba. Lateral cephalometric radiograph versus lateral nasopharyngeal radiograph for quantitative evaluation of nasopharyngeal airway space. Dental Press J. Orthod. [online]. 2014, vol.19, n.4, pp.89-93. ISSN 2176-9451.  http://dx.doi.org/10.1590/2176-9451.19.4.089-093.oar.

OBJECTIVE:

This study compared lateral radiographs of the nasopharynx (LN) and lateral cephalometric radiographs (LC) used to assess nasopharyngeal airway space in children.

MATERIAL AND METHODS:

One examiner measured the nasopharyngeal space of 15 oral breathing patients aged between 5 and 11 years old by using LN and LC. Both assessments were made twice with a 15-day interval in between. Intergroup comparison was performed with t-tests (P < 0.05).

RESULTS:

Comparison between LN and LC measurements showed no significant differences.

CONCLUSION:

Lateral cephalometric radiograph is an acceptable method used to assess nasopharyngeal airway space.
