Infraorbital nerve transpositioning into orbital floor: a modified technique to minimize nerve injury following zygomaticomaxillary complex fractures
OBJECTIVES Transpositioning of the inferior alveolar nerve to prevent injury in lower jaw has been advocated for orthognathic, pre-prosthetic and for implant placement procedures. However, the concept of infra-orbital nerve repositioning in cases of mid-face fractures remains unexplored. The infraorbital nerve may be involved in trauma to the zygomatic complex which often results in sensory dis...
متن کاملNeurosensory changes in the infraorbital nerve following zygomatic fractures.
OBJECTIVE To document the neurosensory changes in the infraorbital nerve following zygomatic fractures managed in various ways. STUDY DESIGN Twenty-five patients were included in the study. Neurosensory function was assessed with calibrated nylon monofilaments, electrical stimulation, heat detection thresholds and response to pin prick in the infraorbital, supraorbital, and mental nerve regio...
متن کاملObjective evaluation of infraorbital nerve involvement in maxillary lesions by means of the blink reflex.
OBJECTIVE To objectively evaluate the effects of maxillary lesions on the infraorbital nerve (ION). METHODS We investigated the latencies (R1, R2) of the blink reflex, stimulating the infraorbital foramen electrically (18 mA, 0.2 millisecond). Twenty-two patients with unilateral maxillary lesions were enrolled. RESULTS Ten patients showed delayed or absent R1 on the lesion side. Four of 20 ...
متن کاملCoronal approach to zygomaticomaxillary complex fractures.
OBJECTIVE Trauma of the zygomaticomaxillary complex constitutes 45% of all midface fractures. In the author's medical unit, the proportion is 40% of all fractures of the facial skeleton. Most zygomaticomaxillary complex fractures can be treated via local incisions, however; multiple, comminuted and late fractures require wide exposure of the fragments in order to adequately reposition them and ...
متن کاملSensory modulation of the blink reflex in patients with blepharospasm.
OBJECTIVE To measure the effects of a prepulse stimulus on the blink reflex responses elicited by an electrical stimulation of the supraorbital nerve in patients with blepharospasm with and without an effective sensory trick. DESIGN Blink reflexes to supraorbital nerve stimulation were preceded in test trials by a prepulse electrical stimulus to the third finger at various leading intervals. ...
