i ntroduction:   the  trigeminocardiac  reflex  (tcr)  refers  to  the  sudden development of bradycardia as well as asystole along with arterial hypotension associated with any manipulation of sensory branches of the trigeminal nerve. clinically, the tcr has been reported to occur during craniofacial surgery. it is crucial to learn about this sudden physiological response during maxillofacial ...

In 1993, I retrospectively reviewed Le Fort III osteotomies performed at Children’s Hospital Oakland. The cases had been performed without distraction and employed internal bone plate fixation. It was disappointing to discover the amount of midface protraction achieved, when measured on lateral cephalograms, was typically 0 to 25% of the magnitude required for reconstruction to facial norms. To...

BACKGROUND Functional rehabilitation of patients afflicted with severe mandibular and maxillary alveolar atrophy might be challenging especially in malformed patients. METHODS Treatment planning using sinus lifting and implant placement before Le Fort I maxillary osteotomy in a patient with severe mandibular and posterior maxillary alveolar atrophy and skeletal class-III conditions due to cle...

AIM The aim of this study was to assess the vitality of maxillary anterior teeth following Le Fort I osteotomy. MATERIALS AND METHODS A total of 245 maxillary anterior teeth in 42 patients were examined by several pulp vitality tests before surgery and 1 to 5 years postoperatively. Data were recorded in SPSS and were statistically analyzed by using Pearson, chi(2), and Fisher exact tests. R...

AIM This study assessed the causes and incidence of miniplate removal during a 5-year period after Le Fort I osteotomy. PATIENTS AND METHODS One hundred forty-two patients had plates inserted for fixation of the maxilla after Le Fort I osteotomy between 2001 and 2004. The Le Fort I segment was rigidly fixed with four 2-mm titanium miniplates and 16 screws. They were followed 1 to 5 years for ...

BACKGROUND The Le Fort I maxillary osteotomy approach for skull base tumor removal in the pediatric age group has not been widely discussed in the literature except for sporadic case reports and limited case series. OBJECTIVES To review our experience with the Le Fort I osteotomy and to propose that it be used as an alternative approach because of its many advantages for the removal of tumors...

PURPOSE It is unclear whether surgical factors can affect the upper lip sensitivity. The aim of this study was to assess the factors that can affect the recovery period of hypoaesthesia of the upper lip after Le Fort I osteotomy, using trigeminal somatosensory evoked potential (TSEP) objectively. PATIENTS AND METHODS Twenty-nine patients with mandibular prognathism underwent Le Fort I osteoto...

OBJECTIVE To analyze the long-term effects of the Le Fort I osteotomy approach for the resection of juvenile nasopharyngeal angiofibroma (JNA) on maxillary growth and dental sensation. DESIGN Prospective collection of structured data. SETTING Tertiary care academic teaching hospital. PATIENTS Between 1993 and 1998, 5 adolescents (aged 10-14 years) constituted the evaluable cohort among 14...

OBJECTIVE To examine the effect of trauma velocity on the pattern of Le Fort I facial fractures. METHOD A retrospective medical record review was conducted on a consecutive cohort of craniofacial traumas surgically treated by a single surgeon between 2007 and 2011 (n=150). Of these cases, 39 Le Fort fractures were identified. Patient demographic information, method of trauma and velocity of i...
