Objective:
Nasal-breathing impairment has been described as a possible determinant of maxillofacial development in children with adenoids/tonsils hypertrophy. However little is known about the possible influence of nasal septum deviation on craniofacial growth in childhood. We conducted a multicenter cephalometric study to compare skeletal and dental features in children with chronic nasal-breathing obstruction secondary to nasal septum deviation and nose-breathing controls.
Methods:
Ninety-eight children (59M, 39F; mean age 8.8 years; age range 7-12 years) with obligate mouth-breathing secondary to nasal septum deviation (group 1) and 98 age- and sex-matched nasal-breathing controls (group 2) were evaluated. Nasal-breathing function was assessed in all patients with clinical history, ENT instrumental examination and anterior active rhinomanometry. Cephalometric parameters were recorded in all subjects.
Results:
Patients of group 1 showed a statistically significant increase of upper anterior facial height (N-palatal plane) and total anterior facial height (N-Me) with regards to group 2. The angular relationships of the sella-nasion, palatal, and occlusal planes to the mandibular plane were greater in group 1 in comparison to controls. The gonial angle (Ar-Go-Me), palatal height and overjet were significantly higher in the mouth-breathing group. A significantly retrognatic position of the maxilla and mandible was recorded in group 1 in comparison to group 2. Most mouth-breathing children showed class II malocclusion, while the majority of control subjects presented normal occlusion. The prevalence of cross-bite was higher in group 1 with respect to controls (p=0.02).
Conclusion:
Children with obligate mouth-breathing due to nasal septum deviations show facial and dental anomalies in comparison to nose-breathing controls. Possible physiologic explanations of our findings are reported.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
