BACKGROUND/AIMS: Open reduction and internal fixation (ORIF) is a standard surgical procedure in jaw trauma and in orthognathic surgery. Insertion of screws is a significant risk for accidental tooth root injury with varying outcomes. Contrary evidences are found in literature due to a variety of study designs. This study was undertaken to address the lacunae and possibly estimate the difference in occurrence of tooth damage during or after ORIF between trauma and planned osteotomies...

We introduce modified nasal to oral tube switch technique for modified alar cinching to prevent alar flare after orthognathic and nasal corrective surgeries. The technique is beneficial to prevent alar flare. Modified alar base cinching is effective in patients with modified tube switch technique. It increased positive results. The technique of tube switch is effective in prevention of alar flare. We suggest multi center randomized studies to know the technical difficulties of tube switch for cinching.

Pierre Robin sequence (PRS) is characterized by the triad micrognathia, glossoptosis, and airway obstruction, commonly associated with cleft palate. This study reports the case of a patient with characteristics consistent with the diagnosis of PRS in the 1(st) week of life. To stabilize the airway, oro-tracheal intubation was performed without success, followed by tracheostomy and glossopexy and after a small improvement in symptoms, it was decided to perform the mandibular distraction osteogenesis (MDO). At the age of 6, her maxillofacial development was within expectations, with patent airway, the presence of deciduous teeth, and without neurological impairment...

BACKGROUND: Soft tissue changes secondary to Maxillary orthognathic surgery are many fold. The alar flare is one among them, which affects the appearance of the patient. Cinch suture has been used to prevent alar flare; but the presence of anaesthetic tube hinders cinching. So, the study was aimed to assess an efficacy of modified nasal to oral tube switch technique for modified alar cinching to prevent alar flare after orthognathic and nasal corrective surgeries. MATERIALS AND METHODS: Patients were randomly allocated in each group, who underwent modified alar base cinching with and without nasal to oral tube switch...
