“…Adenoidian facies was already well described in the 19th century, and between 1960 and 1980, Swedish and UK orthodontists emphasized the role of mouth breathing and enlarged tonsils and adenoid in cranial facial changes [16,17,18,19,20,21,22,23,24,25,26]. …”

In children adenotonsillectomy (AT)\ud is the recommended treatment in the\ud presence of obstructive sleep apnea\ud (OSA) [1]. It should be performed, if\ud needed, in association with nasal inferior\ud turbinate reduction usually\ud with radiofrequency [2]. But as shown\ud in previous reports, upper airway soft\ud tissues treatment is not always successful\ud in completely controlling abnormal\ud breathing during sleep in children,\ud despite the fact that subjective\ud improvement is often reported [3, 4,\ud 5, 6]

“…The expansion facilitates posterior crossbite correction, relief of crowding, increase in airway dimensions and has been used in conjunction with facemask therapy to facilitate maxillary advancement. [1][2][3] The dental and skeletal effects of RME are well documented in the literature. The main skeletal effects produce separation of the mid-palatal suture, more anteriorly then posteriorly, with vertical expansion extending to varying levels.…”

“…[2][3][4][5][6][7][8][9] RME is usually used to correct crossbite and to eliminate crowding by increasing the maxillary arch circumference, and it may improve nasal respiration. 2,[10][11][12] However, problems such as dental and/or alveolar tipping, periodontal (gingival) recession, dental extrusion, and anterior open-bite are common concerns. [13][14][15] Traditionally, the effects of RME are evaluated using casts and/or two-dimensional (2D) radiographs, but reproducibility of 2D radiographs is problematic, and overlapping images are difficult to assess.…”

Objective: To assess the three-dimensional (3D) skeletal response to a standardized 5 mm of rapid maxillary expansion (RME) in growing children (6-15 years) with maxillary width deficiency and crowding. Materials and Methods: A bonded appliance was used prior to the eruption of the maxillary first premolars (Mx4s), and a banded appliance was used thereafter. A consecutive sample of 89 patients (29 boys and 60 girls) from a large pediatric dentistry and orthodontics practice was divided into four groups: 1) 6-8 years old (n 5 26), 2) 9-11 years old with unerupted Mx4s (n 5 21), 3) 9-11 years with erupted Mx4s (n 5 23), and 4) 12-15 years (n 5 19). For all patients, the 3D evaluation of dental and skeletal effects was performed with cone-beam computed tomography (CBCT). Results: For both appliances in all patients, CBCT confirmed a triangular pattern of expansion in both the frontal and sagittal planes. Overall, both appliances produced significant maxillary expansion (.80% of the 5-mm activation), but older children showed a progressively more dental (less skeletal) response. Comparison of the two types of expanders in the crossover sample, children aged 9-11 years, showed that the bonded RME produced the most efficient skeletal expansion in the preadolescent sample. Increased maxillary width at the level of the zygomaticomaxillary suture was the best indicator for development of maxillary arch circumference. Conclusion: Development-dependent appliances (bonded RPE before Mx4s erupt, and a banded device thereafter) provided optimal RME treatment for all children from age 6-15 years.
