Changes in nasal structures following orthopaedic and surgically assisted rapid maxillary expansion

Surgically assisted rapid maxillary expansion: Cone-beam computed tomography evaluation of different surgical techniques and their effects on the maxillary dentoskeletal complex

“…This can be attributed to our definition of J point following the floor of the nose; we know from several studies that the floor of the nose moves occlusally after maxillary expansion, thus carrying the J point to a more constricted area of the maxilla.

The shortest distance between the canine furcation point and the edge of the alveolar bone at the same axial slice (Fig 3, A).…”

Three-dimensional nasal septum and maxillary changes following rapid maxillary expansion in patients with cleft lip and palate:

“…22 The literature is controversial regarding the effects of RME on NS deviation, which occurs more frequently in patients with clefts than in patients without clefts. 23 It was reported that NS deviation tended to straighten, 10,24 remained unaltered, 11,12 interfered with the expansion of the maxilla, or moved along with it during expansion in patients without clefts. 25 In addition, the osteotomy of the NS is generally defended to prevent deviation of the septum during the separation of the maxillary bones, 25 although no significant differences were found between cases with and without osteotomy.…”

“…10 Others have reported that there was no alteration in the NS after RME. 11,12 In addition, although the effects of RME on the upper airways 13 and on the UCLP 8,14 are well documented, there is a lack of studies in the literature that analyzed its effects on the nasal septum in UCLP patients, especially using cone-beam computed tomography (CBCT).…”

Three-dimensional evaluation of upper airway following rapid maxillary expansion: A CBCT study

“…5,6 Furthermore, RME is known to affect the position of the mandible, which may also change the size and volume of the oropharyngeal (OP) airway. 7 The effects of RME over nasal size and volume have been researched with various procedures such as lateral and anteroposterior radiographs, [8][9][10][11][12] acoustic rhinometric methods [13][14][15][16] and multislice computed tomography. [17][18][19][20] Recent advances in cone beam computed tomography (CBCT) and related software have made it possible to visualize and measure the upper airway as a solid structure.…”
