Retropharyngeal schwannoma is rare. To the best of our knowledge, only 18 cases have been published in the English literature. Complete surgical excision is the treatment of choice for schwannomas. Transoral approaches have been applied for smaller lesions, and external cervical approaches are preferred for larger and more complex lesions. In this report, we present a case of large retropharyngeal schwannoma that was excised using an endoscopic-assisted transoral approach with palatal splitting. Postoperative functional and oncologic outcomes were satisfactory with no reported intraoperative/postoperative complications.

Odontogenic infections are a normally locally confined, self-limiting process that is easily treated by antibiotic therapy and local surgical treatment. However, it may spread into the surrounding tissues through a perforation of the bone, and into contiguous fascial spaces or planes like the primary or secondary fascial spaces. If the infection extends widely, it may spread into the lateral pharyngeal and retropharyngeal space. The retropharyngeal space is located posterior to the pharynx. If an odontogenic infection spreads into this space, severe life-threatening complications will occur, such as airway obstruction, mediastinitis, pericarditis, pleurisy, pulmonary abscess, aspiration pneumonia and hematogenous dissemination to the distant organs. The mortality rate of mediastinitis ranges from 35% to 50%. Therefore, a rapid evaluation and treatment are essential for treating retropharyngeal space abscesses and preventing severe complications. Recently, we encountered two cases of a retropharyngeal space abscess due to the spread of an odontogenic infection. In all patients, early diagnosis was performed by computed tomography scanning and a physical examination. All patients were treated successfully by extensive surgical and antibiotic therapy.

Whiplash injury commonly seen in automobile accident. This type of acceleration-deceleration injury may rarely lead to unfavorable outcomes as in the case of retropharyngeal hematoma. Because this lesion has the possibility of compressing the potential airway acutely or gradually, not only the rapid assessment and treatment but also closed observation are needed. We report a case of a 20-year-old man, who sustained a whiplash injury from contact with the headrest of his seat after his car was involved in a rollover. He had no symptom except posterior neck pain initially, but complained odynophagia and acute dyspnea after 10 hours of admission. The diagnostic work-up comprising lateral radiograph, CT imaging disclosed the rare constellation of a retropharyngeal hematoma with cervical spine fractures. Medical treatment and close observation were sufficient for the patient because he had no progressive dyspnea or major dysphagia.

의학적 처치에 의한 기구 삽입과 관계없이 우연히 구인두부의 천공이나 외상을 겪은 후 발생한 후측인두부농양 및 종격동염의 소아에서 보고는 드물다. 이 질환들은 조기에 의심하고 진단과 처치를 하는 것이 중요한데 나이 어린 소아에서는 증상 및 징후가 비특이적일 수 있으므로 진단을 위해 각별한 주의가 요구된다. 또한, 구강내 외상의 병력이 있는 소아에서는 당시에 별다른 증상이 없다하더라도 잠재적으로 심각한 합병증이 발생할 수 있음을 항상 숙지해야 한다. 저자들은 감염의 시발점이 된 경부 심부감염의 증상과 징후는 뚜렷하지 않고 이로 인한 이차적인 흉강 합병증을 주소로 내원한 소아에서 농기흉이 먼저 발견된 후 외상에 의한 후측인두부농양과 급성하행성 괴사성종격동염이 진단되어 항생제 및 광범위한 수술적 치료로 치유된 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

가와사끼병은 급성 전신적 염증성 질환으로, 그 원인은 아직 밝혀지지 않았고, 임상양상은 비특이적으로 많은 소아의 감염성 질환이나 면역학적 질환에서도 볼 수 있다. 저자들은 발열과 경부 임파선병증을 보인 두 증례에서 경부 전산화단층촬영상 인두후부의 농양과 유사한 소견을 보였으나 항생제 치료에 반응하지 않으며 인두 후부의 흡인술에서도 농양이 없던 경우로, 시간이 지나면서 전형적인 가와사끼 증상의 출현과 함께 심초음파에서 방실 판막의 역류를 보여 늦게 진단할 수 있었다. 본 증례에서처럼 발열과 경부임파선병증으로 나타나는 경우에도 가와사끼병을 의심해야 하며, 이 경우 전산화단층촬영에서 인두후부의 농양 유사 병변은 위양성 소견으로 볼 수 있다. 경부임파선병증이 적절한 항생제치료에도 불구하고 발열 등의 증상이 지속되는 경우에는, 심초음파를 포함한 검사를 조기에 시행하여 불필요한 내과적, 외과적 치료를 줄여야 할 필요가 있겠다.

A 73-year-old man with sudden sensory neural hearing loss received a stellate ganglion block. Two hours after the block, the patient complained of newly developed neck discomfort. After an additional two hours, the neck swelled up gradually and neck pain and dyspnea developed. A plain radiograph of neck revealed narrowing of the upper airway; a tracheostomy was performed and the dyspnea was improved. On the next day, the pain site extended to the right scapula and a CT image revealed a huge retropharyngeal hematoma. Hematoma evacuation and bleeder ligation were then performed and the patient was discharged on the fourth day after admission without any complications. A practitioner should always remember to educate the patients about possible complications and undertake intensive observation when performing procedures, even in patients who do not initially present with a compromised airway.

Foreign bodies in upper aerodigestive tract migrating into retropharyngeal space are rarely encountered emergent cases in otolaryngologic fields. A 60-years-old female presented throat pain and lump sense after a meal. Computer tomography showed metallic foreign body impacted in the retropharyngeal space. A hypopharyngeal perforation was suspected by through flexible laryngoscopy and gastrointestinal endoscopy. It was successfully removed by external cervical approach, and we report this case with a review of the related literatures.

Esophageal foreign body are not uncommon problems in the otolaryngologic field. Esophageal foreign body may cause severe complications such as esophageal ulceration, esophageal perforation, periesophagitis, tracheo-esophageal fistula, mediastinitis, pneumothorax pyothorax according to the kinds, shape, size, duration of lodgement of foreign body. The majority of esophageal foreign U which lodge in the esophagus can be removed endoscopically, but the following type of foreign body may require removal by external route. 1. an impacted foreign body 2. a foreign body producing esophagitis after unsuccessful attempts at removal through the esopahgoscope 3. a periesophageal abscess with a foreign body lodging in the abscess itself. Recently, we experienced a case of esophageal foreign body (fish bone) which penetrate the cervical esophageal wall and formed retropharyngeal abscess in 54-year old female. The foreign body are successfully removed and abscess was drained by external route through the lat neck.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, and potentially fatal due to the risk of atlantoaxial dislocation. The disease usually accompanies a retropharyngeal cold abscess, which can cause subsequential otolaryngologic symptoms such asdysphagia, odynophagia, or airway obstruction. Such a patient must be handled with great care to avoid a disaster. The disease is diagnosed with microbiological or other laboratory tests on the pus collected through puncture and aspiration, which will need otolaryngologic skills. For treatment, otolaryngologists play an important role by doing incision and drainage of the retropharyngeal abscess, or by attending the transoral vertebra surgery as partners with spine surgeons who will manage the CVJ lesions and ensure the craniocervical stability.

Extra-articular tenosynovial giant cell tumor (TS-GCT) in retropharyngeal space is a rare case. We found only two case reports in the literature, in which one was located in retropharynx or prevertebral space of the cervical spine. We describe a rare case of TS-GCT in the retropharynx, which was initially misdiagnosed as oropharyngeal cancer. Furthermore, we want to assure that extraarticular diffuse type TS-GCT should be considered in the differential diagnosis of lesions showing low signal intensity in MRI scan.
