A foreign body lodged in the sub-mental space through to the retro-pharyngeal area: a review of anatomical risks and surgical approaches

Background Foreign body inclusions are rare in head and neck. They are challenging in regard to anatomical risks and surgical approaches. This is the case of a particular foreign body with a curious trajectory, associated with a brief review of anatomical risks and surgical approaches. Case presentation This is the case of a 25-year-old male who has been attacked with a sharp object, which caused an inclusion of a part of the foreign body in the sub-mental and pharyngeal areas. The clinical exam showed a painful bulging in the sub-mental area, with moderately hemorrhagic sputum and difficulty while swallowing. The intra-oral exam showed a foreign body that was located at the right side of the base of the tongue, and which goes backwards and outwards to penetrate retro-pharyngeal mucosa. The patients underwent an angio-CT scan, which showed a curious fine and sharp metallic object, without direct signs of lesions to the jugular vein or carotid artery or any collateral branches. The patient underwent extraction through cervical approach, with satisfying bleeding control. Intra-oral exploration showed a retro-pharyngeal lesion of 2 cm, without particular bleeding. The cervical lesion and retro-pharyngeal lesions were closed. The lesion at the base of the tongue was of 1 cm, palpable but not accessible to sutures, and a naso-pharyngeal tube was inserted. The patient presented very satisfying post-operative outcome, without any complications. Conclusion When dealing with foreign bodies of head and neck, physicians must be precocious and prepared for the risk of bleeding after extraction. Thorough radiological exploration is necessary as long as the patient is stable. Direct and indirect radiological signs allow the clinician to understand the nature and the trajectory of the object, as well as the damage to collateral structures.

Case Report: Bow Hunter's Syndrome Caused by Compression of Extracranially Originated Posterior Inferior Cerebellar Artery

Bow hunter's syndrome (BHS) is most commonly caused by compression of the vertebral artery (VA). It has not been known to occur due to an extracranially originated posterior inferior cerebellar artery (PICA), the first case of which we present herein. A 71-year-old man presented with reproducible dizziness on leftward head rotation, indicative of BHS. On radiographic examination, the bilateral VAs merged into the basilar artery, and the left VA was predominant. The right PICA originated extracranially from the right VA at the atlas–axis level and ran vertically into the spinal canal. During the head rotation that induced dizziness, the right PICA was occluded, and a VA stenosis was revealed. Occlusion of the PICA was considered to be the primary cause of the dizziness. The patient underwent surgery to decompress the right PICA and VA via a posterior cervical approach. Following surgery, the patient's dizziness disappeared, and the stenotic change at the right VA and PICA improved. The PICA could be a causative artery for BHS when it originates extracranially at the atlas–axis level, and posterior decompression is an effective way to treat it.

Efficacy of the Suboccipital Paracondylar-Lateral Cervical Approach: The Series of 64 Jugular Foramen Tumors Along With Follow-Up Data

ObjectiveComplete resection of jugular foramen tumors with minimal cranial nerve complications remains challenging even for skilled neurosurgeons. Here, we introduce a modified paracondylar approach, named the suboccipital paracondylar-lateral cervical (SPCLC) approach for this purpose. We also share the follow-up data of our series and discuss the advantages and limitations of this modified paracondylar approach.MethodsWe included 64 patients with jugular foramen tumors who underwent surgery by the same senior neurosurgeon between November 2011 and August 2020. All patients were treated with the SPCLC approach, which aimed for gross total tumor removal in a single-stage operation. The clinical characteristics, including preoperative and postoperative neurological status, the extent of surgical resection, and follow-up data were retrospectively acquired and evaluated.ResultsThere were 48 schwannomas, nine meningiomas, three paragangliomas, one hemangiopericytoma, one chordoma, one endolymphatic sac tumor, and one Langerhans’ cell histiocytosis. The median age of our patients was 43 years (range: 21–77 years). Dysphagia, hoarseness, and tongue deviation were observed in 36, 26, and 28 patients, respectively. Thirty-two patients had hearing function impairments, including hearing loss or tinnitus. Gross total resection was achieved in 59 patients (59/64, 92.2%). Gamma Knife treatment was used to manage residual tumors in five patients. Postoperatively, new-onset or aggravative dysphagia and hoarseness occurred in 26 and 18 cases, respectively. Nine patients developed new-onset facial palsy, and one patient developed new-onset hearing loss. There were no cases of intracranial hematoma, re-operation, tracheostomy, or death. At the latest follow-up, hearing loss and tinnitus had improved in 20 cases (20/32, 62.5%), dysphagia alleviated in 20 cases (20/36, 55.6%), and hoarseness improved in 14 cases (14/26, 53.8%). Over a mean follow-up period of 27.8 ± 19.5 months (range: 3–68 months), tumor recurrence was observed in one patient.ConclusionThe SPCLC approach, modified from the paracondylar approach, and was less invasive, safe, and efficient for certain jugular foramen tumors. Taking advantage of the anatomic understanding, clear operational vision, and appropriate surgical skills, it is possible to achieve gross total tumor removal and the preservation of neurological function.

Parapharyngeal Lymph Node Metastasis From Papillary Thyroid Carcinoma

Metastatic parapharyngeal lymph nodes (LNs) from papillary thyroid carcinomas (PTC) are uncommon and can easily remain undetected. We describe a case that involves a 62-year-old woman treated for a PTC, who presented a rise in serum thyroglobulin (TG) levels. A computed tomography scan was performed, and revealed metastatic nodes in the left parapharyngeal space (PPS). A surgical resection of the nodes was performed with external cervical approach. A histological exam confirmed the diagnosis of a metastatic LN of a PTC. The aim of this report is to emphasize on the possibility of parapharyngeal metastatic nodes in PTC and to describe the diagnosis methods, treatment options, and impact on the prognosis.

Preoperative Evaluation of Substernal Goiter by Computed Tomography in the Extended Neck Position

Sternotomy is indicated when a goiter cannot be resected via a cervical incision, such as in the case of a substernal goiter extending beyond the aortic arch. In this article, we report a case of a large substernal goiter that was successfully removed using the cervical approach only. This is a case of a 68-year-old woman, diagnosed with goiter 20 years ago, who complained of a neck mass enlargement with associated cough. Pathological examination revealed no malignancy. Computed tomography (CT) scan showed an 11-cm thyroid mass reaching the level of the aortic arch. Preoperatively, we evaluated the substernal extent of the goiter via CT in the extended neck position to decide whether sternotomy was necessary. With the patient’s neck extended, the goiter withdraws cranially above the aortic arch. The mass was then removed via the cervical approach without sternotomy. Preoperative CT in the extended neck position was thus deemed helpful in deciding whether or not sternotomy was required.

H-Type Tracheoesophageal Fistula Masquerading as Grade V Gastroesophageal Reflux in a Neonate

Tracheoesophageal fistula (TEF) without associated esophageal atresia is a rare congenital anomaly. Diagnosis in neonatal period is usually not made and most of the patients are treated as cases of pneumonia. We report a case of H-type TEF, which was initially diagnosed as grade V gastroesophageal reflux on contrast esophagogram and bronchoscopy done revealed H-type fistula. Through cervical approach, fistula was repaired and baby had uneventful postoperative outcome. High index of clinical suspicion and early diagnosis can provide a better prognosis.

152 SURGICAL PROCEDURE AND OUTCOME OF MEDIASTINOSCOPIC RADICAL ESOPHAGECTOMY FOR ESOPHAGOGASTRIC JUNCTION CANCER

We started performing mediastinal lymph node dissection by a laparoscopic transhiatal approach (LTHA) in 2009. To date, 371 patients had undergone our method during various esophageal surgical procedures, including esophagogastric junction cancer (EGJC). Furthermore, we started performing single-port mediastinoscopic cervical approach in 2014, and developed a simple technique for transmediastinal radical esophagectomy (TMr) without thoracic approach (258 cases). Forty patients with EGJC were also treated by TMr. Methods Left single-port mediastinoscopic cervical approach was performed with pneumomediastinum. Mainly for advanced SCC, upper mediastinal lymph node dissection including recurrent laryngeal nerve LNs was performed with intraoperative monitoring using NIM system. Next, LTHA was performed for en bloc mediastinal lymph node dissection. The esophageal hiatus was opened, and working space was secured by Long Retractors. The posterior plane of the pericardium was extended. The posterior side of LNs was then separated. Finally, while lifting LNs like a membrane, they were resected from bilateral mediastinal pleura. Reconstruction with narrow gastric conduit was performed through substernal tract. Results Patients with EGJC performed TMr were analyzed (n = 40, SCC/Adeno/Others = 21/17/2). Upper mediastinal lymph node metastasis was found in 6 cases (SCC/Adeno = 3/3), middle mediastinal lymph node metastasis was found in 2 cases (SCC/Adeno = 1/1), and all of them had advanced tumors. Their perioperative outcome were compared with those performed the right thoracotomy (n = 41). The operative time and bleeding were decreased by TMr. The number of resected mediastinal lymph nodes, pR0 rate, and mediastinal recurrence in the two groups were not different. In 95.0% of patients treated by TMr, extubation was performed at 0 POD. Postoperative respiratory complications was decreased by TMr (TMr:7.5%, thoracotomy:17.1%). Conclusion This procedure, TMr, resulted in a good surgical view, safe en-bloc mediastinal lymph node dissection, and the decrease of postoperative respiratory complications in patients with EGJC.
