Severe maxillary deficiency is often seen in cleft lip and palate patients due to multiple factors such as congenital defect, traumatic effect of surgeries and constriction of scar tissue, which causes moderate to severe crowding and anterior and posterior crossbite. Orthodontic treatment is usually difficult and time consuming. Upper arch expansion and maxillary protraction are often carried out to release transverse and sagittal intermaxillary discrepancy. Orthodontic treatment for cleft patients is different from that of non-cleft patients...

Dentofacial disharmony in patients with cerebral palsy (CP) can lead to low self-esteem and functional limitations. However, medical and behavioral challenges in patients with developmental disorders often prevent dental practitioners from offering the necessary treatment. This report describes the clinical interdisciplinary management of a 20-year-old man with CP, including orthodontic, periodontal, and orthognathic surgery therapy. The patient presented with the chief complaint of having difficulty chewing, was wheelchair dependent, had poor orofacial muscle control, and exhibited a Class III malocclusion with a skeletal anterior open bite...

The aim of present case report is to discuss surgical lip repositioning technique for the management of excessive gingival display related with vertical maxillary excess and increase mobility of the upper lip. By restricting the muscle pull by elevator lip muscles, this procedure reduces excessive gingival display during smiling. For patient, this procedure is safe, less invasive with minimal side effects and an alternative to orthognathic surgery in the correction of gummy smile.

Obstructive sleep apnea syndrome (OSAS), commonly associated with mandibular micrognathia, is a serious condition that can lead to various devastating cardiovascular and neurocognitive consequences. Patients of OSAS with micrognathia present with many functional and esthetic problems. Therefore, comprehensive management of these patients requires multiple surgeries and frequent follow-up. Several surgical and non-surgical treatment options have been proposed for the treatment of OSAS. Distraction osteogenesis (DO) in maxillofacial region, although a newer treatment modality, is being increasingly favoured by many surgeons because of its many advantages over other treatment methods...
