Eagle syndrome, also known as elongated styloid process, is a condition first described by Watt Eagle in 1937. It occurs when an elongated styloid process or calcified stylohyoid ligament causes recurrent throat pain or foreign body sensation, dysphagia, or facial pain. ⋯ It is usually hard to diagnose because the symptoms related to this condition can be confused with those attributed to a wide variety of facial neuralgias. In this article, a case of Eagle syndrome exhibiting unilateral symptoms with bilateral elongation of styloid process is reported.

Growth factors contained in platelet-rich plasma (PRP) can induce osteoblast differentiation in certain studies, whereas in others, osteogenesis of PRP on mandible bone defects has not been proved clinically. The aim of the study was to investigate the effect of autologous PRP on the osteogenic potential of combining bovine porous bone mineral (BPBM) and bio-guide membrane (BGM) in promoting mandible bicortical bony defects in rabbits. ⋯ The study suggested that PRP combination of BPBM and BGM had significant therapeutic effects on mandible bicortical bony defects of rabbits. The effects are associated with the high concentration of platelet in PRP and the porous configuration of BPBM. Although we cannot reveal the detailed statistical relationship of PRP on promoting BPBM/GBM osteoinductive effects, PRP demonstrated superior results of bone regeneration.

Polyetheretherketone (PEEK) has emerged as one of the most promising alloplastic materials for calvarial reconstruction because of a number of desirable qualities including resistance to heat and ionizing radiation, biocompatibility, biomechanically similar to native bone, and being nonferromagnetic for postoperative monitoring. We aimed to evaluate and compare the outcomes of alloplastic cranioplasty performed with PEEK, titanium mesh only (Ti-only), and titanium mesh with acrylic cement (Ti-AC); titanium mesh has previously recorded many successes with low complication rates. ⋯ Early results suggest that PEEK may be superior to Ti-only or Ti-AC as an alloplastic cranioplasty choice. Further research should include randomized trials between computer-aided, prefabricated titanium and PEEK cranioplasties with larger sample sizes and longer follow-up.

Remote epidural hematoma (REDH) is an uncommon complication of decompressive craniectomy. Remote epidural hematomas of the parietal occiput region have been reported only rarely. ⋯ Postoperatively, serial computed tomographic scans performed 3 days later showed that the REDH had been completely evacuated. Two months later, the patient regained full consciousness and obtained a near-complete recovery except for right facial paralysis.

A novel application of computer-aided design and manufacturing for reduction cranioplasty.
Macrocephaly is a rare presentation of untreated hydrocephalus. In cases where medical management has failed, macrocephaly can be managed with reduction cranioplasty. Traditionally, reduction cranioplasty is highly dependent on intraoperative tailoring of bone segments to obtain the best possible result and involves high risks of associated severe blood loss and mortality. ⋯ We also utilized computer-aided manufacturing to produce cutting guides, positioning guides, and models to increase precision and improve the final positioning of the cranium. Computer-aided design and manufacturing technology has enabled a shift of the planning burden of complicated craniofacial reconstructions from the intraoperative to the preoperative phase. With a completed plan and premade guides and models, it is possible to minimize the risks, improve efficiency, and obtain a precise, aesthetic result.
