White-Eyed Orbital Blowout Fracture With Oculocardiac Reflex Secondary to Extraocular Entrapment in a Pediatric Patient.

White-eyed orbital blowout fractures in the pediatric population can present with acute onset diplopia, ophthalmalgia, and abnormal duction. These findings are attributed to the tendency of younger bone to break and reapproximate owing to greater elasticity. This phenomenon, commonly referred to as the greenstick fracture, increases the risk of entrapment of surrounding soft tissue structures in orbital floor fractures. Further concern arises in the presence of an oculocardiac reflex, which requires urgent intervention to prevent serious bradycardia. Prolonged entrapment can go unnoticed and result in irreversible ischemic damage to entrapped tissues. This case discusses the presentation 16-year-old female who sustained a left sided, white-eyed blowout fracture from a face-first ground level fall. On admission, she displayed restrictive strabismus and mild periorbital edema around the left eye. Vertical gaze was restricted when looking inferiorly on the affected side. With sustained upward gaze, her heart rate decreased from 99 to 81 beats per minute. High-resolution non-contrast computed tomography scans of the head showed entrapment of the inferior rectus muscle and periorbital fat. Liberation of entrapped tissues with reduction of bony segments was performed urgently, utilizing a MEDPOR® Titan 3D orbital floor plate and secured with two screws. The patient had an uneventful postoperative period and showed considerable improvements in periorbital edema, duction, and ophthalmalgia on the affected side. In addition, the oculocardiac reflex could no longer be elicited on prolonged upward gaze. Mild and improving paresthesia was noted in the maxillary distribution of the left trigeminal nerve. Sensory deficits like this are the result of fracture communication with the infraorbital canal, which may cause irritation of the infraorbital nerve responsible for sensation by the maxillary division. By postoperative week 7, she had complete resolution of periorbital edema, indiscernible duction abnormalities, and complete healing of surgical incision sites, and an oculocardiac reflex could not be elicited.

Remote monitoring of head and neck free flaps using near infrared spectroscopic tissue oximetry.

PURPOSE: Near infrared spectroscopy (NIRS) measures tissue oximetry and perfusion of free tissue transfer with the advantage of remote wireless monitoring for free tissue transfer. It has been widely used in breast and extremity reconstruction but has had limited adoption in the head and neck. MATERIALS AND METHODS: A retrospective review of head and neck microvascular reconstruction by three different surgical services over 15 months at one tertiary care hospital was performed. Demographics, flap type, monitoring technique, complications, and flap outcomes were recorded. Monitoring techniques were (1) implantable/handheld Doppler or (2) NIRS. Flap monitoring outcomes were evaluated using multivariate analysis. RESULTS: 119 flaps were performed by four surgeons with a success rate of 92% (109/119). Flaps were monitored with Doppler (40%) or NIRS (60%). There was no difference in flap success based on monitoring technique. An ROC analysis identified that the optimal cutoff in immediate StO2 for classifying flap success at discharge was 68%. CONCLUSIONS: NIRS was successfully implemented in a high-volume head and neck reconstructive practice. NIRS remote monitoring allowed for flap surveillance without requiring in-hospital presence and was able to identify both arterial and venous compromise.

Assessment and Treatment of Behavioral Disorders in Children with Hearing Loss: A Systematic Review.

OBJECTIVE: There is evidence that children who are deaf and hard of hearing (DHH) have a higher incidence of behavioral disorders. Assessment of behavioral health in this population is often complicated by language developmental delays, which may result in unrecognized and untreated behavioral problems. The purpose of this study is to assess the association of behavioral disorders among children who are DHH and to explore behavioral interventions for children in this population. DATA SOURCES: PubMed, CINALH, PsychINFO, and Web of Science. REVIEW METHODS: Search terms included the following: problem behavior, child behavior disorders/diagnosis, child behavior disorders/psychology coupled with hearing loss, cochlear implants, hearing aids, or deafness. Studies from the last 30 years (1985-2016) were included. The articles were reviewed independently by 3 reviewers. RESULTS: Thirty-six articles met criteria. There was an association between internalizing behaviors and hearing loss among children, which may persist after cochlear implantation. These problems may be more pronounced for children with additional disabilities. Conduct and hyperactivity disorders as well as emotional and executive function problems among children who are DHH may be related to poor language development. There was limited evidence regarding interventions to address the behavioral disorders of DHH children. CONCLUSIONS: There is a significant body of evidence demonstrating behavioral problems among DHH children but a lack of clear understanding of the mechanisms involved. There is limited evidence on interventions to address the behavioral problems of DHH children. Future research is warranted to mitigate the long-term effects of disruptive behavior among these children.
