Aim And Method: We developed a method to measure the forces occurring during rapid maxillary expansion and carried out the University of Ulm rapid maxillary expansion method, similar to that of Chatellier and Chateau, in ten patients.
Results: The forces occurring on the maxilla increased up to 120 N. There was considerable variation in force level from patient to patient. After "rupture" of the midpalatal suture, the forces decreased. The remaining forces seemed to be the result from stress on soft tissue and bone.

Objectives: To evaluate nasal septum changes after rapid maxillary expansion (RME) during the mixed dentition and to verify the association between quantitative and qualitative assessments of nasal septum deviation (NSD) by ear, nose, and throat (ENT) specialists.
Materials And Methods: The sample comprised 24 patients (11 male, 13 female) with a mean age of 7.62 ± 0.
A combination of low-temperature radiofrequency thermocoagulation and pulsed radiofrequency of the bilateral Gasserian ganglion for bilateral trigeminal neuralgia due to multiple sclerosis: a case report.

Background: Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related complications.
Case Presentation: A 49-year-old male with multiple sclerosis exhibited persistent dull pain and paroxysmal electric shock-like pain in his bilateral maxillary molars and mandible.
Objectives: To evaluate the treatment effects of the modified miniscrew-assisted rapid palatal expander (MARPE) and rapid palatal expander (RPE) with distalizers in patients with Class II malocclusion and maxillary crowding.
Materials And Methods: The sample comprised 28 skeletal Class I adolescents with dental Class II malocclusion and maxillary crowding of >4 mm who received nonextraction treatment. Fourteen patients were treated with a modified MARPE with distalizer (MMD), while another 14 patients were treated with a modified RPE with distalizer (MRD).
The Role of Rapid Maxillary Expansion in the Management of Obstructive Sleep Apnoea: Monitoring Respiratory Parameters-A Systematic Review and Meta-Analysis.

Department of Orthodontics, Faculty of Medicine and Health Science, Catholic University of Valencia, 46001 Valencia, Spain.
Obstructive sleep apnoea (OSA) is a sleep-related breathing condition that involves the presence of episodic disruptions to the sleeping pattern due to partial or complete airway obstruction. There are a range of treatment options that exist to alleviate the symptoms of this condition including CPAP, mandibular advancement, and maxillary expansion techniques. This systematic review and meta-analysis of published articles aims to determine if rapid maxillary expansion ("RME") is an effective treatment option in the management of OSA, using quantitative parameters of AHI and SpO.

This case report presents the multidisciplinary treatment of a male patient with a complex form of frontonasal dysplasia who presented with a 0 to 14 facial cleft, mild hypertelorism, absence of the nasal medial process of the nose, and frontonasal encephalocele. Cranial and plastic surgeries were performed to correct hypertelorism and improve the esthetic appearance of the frontonasal region. In the permanent dentition, the patient presented a Class II, division 1 malocclusion with severe maxillary constriction and bilateral posterior crossbite.
