“…The posterior region or the nasal airway showed greater dimensional changes than the anterior or soft tissue part of the nose. Similar findings have been previously reported , and were attributed to the nasal anatomy; because of the greater dimensions of the posterior region of the nasal cavity, the smallest amount of transverse expansion leads to a more pronounced change in the volume.…”

This study aimed to assess the effects of bone-borne and tooth-borne surgically assisted rapid maxillary expansion on the volumes of the nose and nasal airway 2 yr after maxillary expansion. This prospective cohort study included 32 patients with transverse maxillary hypoplasia. Expansion was performed with a tooth-borne distractor (Hyrax) in 19 patients and with a bone-borne distractor [transpalatal distractor (TPD)] in the remaining 13. Cone beam computed tomography scans and three-dimensional (3D) photographs of the face were acquired before treatment and 22 ± 7 months later, and were used to evaluate the volumes of the nose and nasal airway. Nasal volume increased by 1.01 ± 1.6% in the Hyrax group and by 2.39 ± 2.4% in the TPD group. Nasal airway volume increased by 9.7 ± 5.6% in the Hyrax group and by 12.9 ± 12.7% in the TPD group. Changes in the nasal volume and in the nasal airway volume between the pre- and post-treatment measurements were statistically significant, whereas differences between the treatment groups were not; 22 months after surgically assisted rapid maxillary expansion, the increases in the nasal volume and in the nasal airway volume were comparable between tooth-borne and bone-borne devices.

“…Due to its specific structure, any increase in the nasal cavity dimensions improves its patency. 35 Changes in a transverse dimension between 6-6 teeth and reduction in the angle 6-6_ang are interesting. These data indicate effective expansion of bone fragments, and changes in the angles are correlated with the nasal base expansion and the 6-6 dimension.…”

Available online xxx Keywords:Maxillary hypoplasia SARME Transversal hypoplasia Distraction osteogensis Transpalatal distraction (TPD) a b s t r a c t Introduction: A transverse maxillary hypoplasia is a deformation often observed in orthodontic patients. Various techniques are used to treat this problem. Aim: The aim is to present results of transversal maxillary hypoplasia treatment with a bone-borne device. Material and methods: A retrospective analysis included 27 patients, age 17-26 years (17 AE 2.6). Dental casts and X-ray were made before operation period (T1), and post distraction (T2). On the casts were determined points: on cusps of maxillary canines (3-3), first maxillary premolars (4-4) and first maxillary molars (6-6). Angles and distances were measured on standard posterior-anterior (PA) images. Results and discussion: At the 3-3 level, the average expansion was 5.8 mm, at the 4-4 level the average expansion was 7.3 mm, at the level of 6-6 palatial cusps the average expansion was 6.11 mm. Measurements in the PA X-ray were performed at the nasal cavity, with the average dimensions being 29.03 mm before treatment, and 31.95 mm post-treatment. The angle was measured between first molars (6-6_ang) and the anterior nasal spine before and after treatment, with a significant change in that angle from 98.938 on average to 102.898 after distraction. Conclusions: Use of maxillary distraction osteogenesis with bone-borne device in maxillary expansion is an effective treatment method. Maxillary expansion results in increase of the nasal cavity. Used distractor is easy to operate for the patient.# 2015 Warmińsko-Mazurska Izba Lekarska w Olsztynie.

“…The introduction of rapid prototyping technologies into rhinology allows us to base and predict the functional result of the operation, not only according to mathematical modelling of the process of air flow through the nasal cavity during breathing, but also taking into account the analysis of full-scale aerodynamic models of the studied area. The introduction of such simulation technologies takes the planning process of surgical operations to a qualitatively new level and improves the reliability of the results of procedures associated with predicting the functional results of surgical interventions [3,4,13,15].…”

The project "Implementation of rapid prototyping for modelling the upper respiratory tract in normal and typical pathologies" investigates the urgent problem of improving the reliability of diagnosis and effectiveness of treatment of disorders of the nasal breathing. Possibilities of modern 3D-printing technology for creation of individual natural anatomical models of the upper respiratory tract and determination of their aerodynamic characteristics are considered. The characteristics of the laminar boundary layer of the air flow in the parietal region of the nasal cavity are investigated under different modes of breathing in normal and with typical disorders of the nasal breathing. The concept of investigation of the aerodynamic indices of the anatomical structures of the respiratory system by the results of test tests of individual full-scale 3D models, obtained by the data of spiral computed tomography, is being developed. Theoretical bases of the method of computer planning of restorative rhinosurgical interventions in patients with chronic diseases of the nasal cavity are grounded, based on the change of the configuration of the anatomical structures of the nasal cavity taking into account the aerodynamic parameters of respiration. Modern distance learning and testing tools are being created to demonstrate the technology developed, to provide theoretical knowledge, practical skills and to solve situational tasks for a wide range of specialists. Development and research of natural patterns of the upper respiratory tract allows for supplementing and expanding the knowledge about the aerodynamic characteristics of the nasal cavity, to make decisions about therapy in a short period of time. Experience of the Laboratory of the Institute for Multiphase Processes (IMP) of the Leibniz Universität Hannover (LUH) in the development and use of rapid prototyping capabilities in biotechnology will provide technical support to the project.
