Two groups created, Group 1(75) outpatients and control Group 2(70) hospital patients. Prevertebral soft tissue swelling(PVSTS) was measured anterior to C2 and C6 on plain lateral cervical radiographs preoperatively and one week postoperatively and fusion assessed at two years. RESULTS There was no intergroup significance between preoperative and postoperative visual analogue scales(VAS)and neck disability index(NDI) scores between Group 1 and 2. Mean preoperative PVSTS in Group 1 was 4.7 ± 0.2 mm at C2 level and 11.1 ± 0.5 at C6 level compared to Group 2 mean PVSTS of 4.5 ± 0.5 mm and 12.8 ± 0.5, P = 0.172 and 0.127 respectively. There was no radiographic or clinical evidence of adverse reaction noted. In Group 1 mean postoperative PVSTS was 5.5 ± 0.4 mm at C2 and 14.9 ± 0.6 mm at C6 compared Group 2 mean PVSTS was 4.9 ± 0.3 mm at C2 and 14.8 ± 0.5 mm at C6, P = 0.212 and 0.946 respectively. No significant increase in prevertebral soft tissue space at C2 and C6 level demonstrated.CONCLUSION ACDF with adjunct DBM packed PEEK cages showed a statistical significant intragroup improvement in VAS neck pain scores and NDI scores(P = 0.001). There were no reported serious patient complications; post-operative radiographs demonstrated no significant difference in prevertebral space. We conclude that ACDF with DBMpacked PEEK cages can be safely done in an ASC with satisfactory outcomes.展开更多

The diagnosis is most often considered and made based on a characteristic vesicular rash that presents in a unilateral dermatomal distribution and is usually accompanied by a painful neuritis. Not uncommonly, the pain presents a few days before the rash becomes evident and may even occur without the rash appearing. When this happens patients may be subject to further diagnostic testing seeking alternative diagnoses, as herpes zoster is known to mimic a variety of other non-cutaneous organ system entities. Although the thoracic and lumbar dermatomes are the affected most frequently, in approximately one-fifth of cases the cranial nerves are involved either singularly or in combination. Trigeminal nerve zoster is of particular concern as it poses a risk of developing into zoster ophthalmicus with subsequent keratitis and uveitis resulting in permanent vision impairment. Involvement of the second (maxillary) and third (mandibular) branches of this 5th cranial nerve are less common and may present with signs and symptoms of a primary dental process. The infrequency and unfamiliarity of herpes zoster odontogenic manifestations can lead to unnecessary investigation and treatment. Apropos such a case we review the epidemiology, pathophysiology, signs, and symptoms of odontogenic herpes zoster.展开更多
