A tragic accident occurred in a day care center when a 5 year old child fell face down with a plastic toy asparagus spear in his mouth, puncturing the soft palate and dissecting the internal carotid artery. Approaches utilized in the risk analysis include: literature review, safety standards research, accident statistics survey, biomechanical testing, and evaluation of alternative toy asparagus designs. The goal of this investigation is to make toy designers and users more aware of the puncture/impaling hazard and to identify design alternatives to prevent similar injuries from occurring.

Recurrent Nasopharyngeal Carcinoma

Objective Salvage endoscopic nasopharyngectomy (ENPG) is a reasonable choice for resectable recurrent nasopharyngeal carcinoma (rNPC). However, in past decades, complete removal of the tumor was not feasible when the recurrent lesion was adjacent to the internal carotid artery (ICA). The present article introduces innovative strategies to ensure sufficient surgical margins while avoiding accidental injury to the ICA. Study Design Retrospective study. Setting Tertiary care center. Methods We retrospectively reviewed rT2-3 rNPC patients with tumor lesions adjacent to the ICA (<5 mm) who underwent ENPG at the Sun Yat-sen University Cancer Center between January 2015 and June 2020. Thirty-seven patients were selected for this study. Seventeen patients underwent ENPG using direct dissection, 10 patients underwent endoscopic-assisted transcervical protection of the parapharyngeal ICA combined with ENPG, and 10 patients underwent ICA embolization followed by ENPG. Results With a median follow-up duration of 31 months (range, 5 to 53 months), the 2-year overall survival, progression-free survival, locoregional recurrence-free survival, and distant metastasis-free survival rates of salvage ENPG for rNPC adjacent to the ICA were 88.7%, 72.0%, 72.0%, and 97.3%, respectively. The incidences of grade 1-2 and grade 3-5 postoperative complications were 16.2% and 13.5%, respectively. Two patients experienced ICA rupture during direct dissection but were out of danger after vascular embolization therapy. One patient had a positive margin. Two patients had severe nasopharyngeal wound infections with mucosal flap necrosis. Conclusion ENPG combined with ICA pretreatment allows the feasible and effective resection of rNPC lesions adjacent to the ICA.

A three year old boy died when a dining room chair he was sitting on fell backward, triggering bleeding along his spinal cord. Approaches utilized in the danger analysis include: accident reconstruction, safety literature review, safety standards research and testing, accident statistics survey, and evaluation of alternative dinette chair designs. The primary goal of this investigation is to make dinette chair designers, retailers, and users more aware of the tip over danger and to identify design alternatives to help reduce the number of these types of injuries.

First Case

Objective To review the literature concerning the management of dental needles broken off into the deep spaces of the neck, to report what we believe is the first case of a fractured dental needle migrating into the jugular foramen, and the unconventional use of endovascular intervention to retrieve the needle fragment. Design Case report with review of literature. Setting Academic tertiary care center. Participants Intervention was performed by the otolaryngology–head and neck surgery, vascular surgery, and neurovascular interventional radiology teams. Results Transoral exploration, including palatal split and exposure of the poststyloid parapharyngeal space with C-arm image guidance, was unable to retrieve the broken needle, which traversed the internal carotid lumen with the distal end entering the jugular foramen. Through endovascular intervention, the neurovascular interventional radiology team captured the proximal end of the needle and retrieved it through the femoral artery. The patient recovered uneventfully. Conclusion Fracture and loss of oral injection needles remain a persistent and preventable problem. This case demonstrates a novel, minimally invasive, well-tolerated, and successful method to extract a fractured needle that migrated into the lumen of the internal carotid artery at the level of the skull base.

Deep Neck Infections

Internal carotid artery pseudoaneurysm is a rare complication of deep neck infections. The authors report the case of a 17-year-old male who presented to the Department of Otorhinolaryngology with an acute tonsillitis requiring tonsillectomy. Four weeks after the surgery the patient was readmitted because of progressive swallowing, trismus, and worsening headache. Computed tomography revealed a pseudoaneurysm of the left internal carotid artery in the extracranial segment. A bare Wallstent was implanted primarily and a complete occlusion of the pseudoaneurysm was achieved. The endovascular approach is a quick and safe method for the treatment of a pseudoaneurysm of the internal carotid artery.
