Foreign body aspiration (FBA) into the tracheobronchial tree could be life threatening requiringprompt intervention. Any objects placed in the oral cavity put patients at a risk of aspirating or swallowing the objects slipped or broken by physical injuries. Here, we report a case of 30 yr old patient with FBA during gold crown replacement was successfully treated with the use of the flexible bronchoscope. Case: A 30 yr old woman was admitted to Seoul National Dental Hospitalfor an amalgam restoration. She was scheduled to gold crown restoration for replacement of the damaged amalgam at #37 site. After performing crown lengthening procedure, the aspiration of gold crown occurred during the cementation of the crown. After aspiration, the patients complained of the subjective distress of respiration. Chest radiograph revealed that gold crown was enlodged to the left bronchus. Flexible fiberoptics was inserted to the bronchus to remove the aspirated crown. Fiberoptic assisted removal of the aspiratedcrown was successfully performed. After removal, there was no radiopaque material in the left bronchus on follow-up chest radiograph. Discussion: When aspiration of dental materials occurs, flexible fiberoptic can be used in the treatment of FBA. It is also very useful to take preventive management such as rubber dam, application of dental floss in dental procedure where there is high likelihood of FBA.

Patients with cleft lip and palate (CLP) must undergo corrective surgeries during infancy and early childhood. Many patients with CLP undergo orthognathic surgery during their childhood for correction of skeletal asymmetries or pharyngoplasty with a pharyngeal flap to improve the quality of speech and velopharyngeal function. During orthognathic surgeries, nasotracheal intubation is performed under general anesthesia. In our case report, the patient had undergone palatoplasty and pharygoplasty previously. During the orthognathic surgery, a flexible fiberoptic bronchoscope-guided nasotracheal tube was inserted through the pharyngeal flap ostium; however, active bleeding occurred in the nasopharynx. Bleeding occurred because the flap was torn. After achieving hemostasis, the surgery was completed successfully. Thus, if a patient may show the potential for velopharyngeal port obstruction, nasotracheal intubation should be performed with utmost care.

A 47-year-old woman was referred for surgical treatment of osteomyelitis of the mandible. She had already undergone three previous surgeries. Pre-anesthetic airway evaluation predicted a difficult airway, due to the thin, retro-positioned mandible, tongue, and atrophic changes in the lips and soft tissue. We inserted packing gauzes in the buccal mucosa for easier mask fitting and ventilation. During direct laryngoscopic intubation with a nasotracheal tube (NTT), fracture of a thin mandible can easily occur. Therefore, we used a fiberoptic bronchoscope to insert the NTT. After surgery, we performed a tongue-tie to protect against airway obstruction caused by the backward movement of the tongue during recovery. The patient recovered without any complications. We determined the status of the patient precisely and consequently performed thorough preparations for the surgery, allowing the patient to be anesthetized safely and recover after surgery. Careful assessment of the patient and airway prior to surgery is necessary.

Intraoperative airway obstruction is perplexing to anesthesiologists because the patient may fall into danger rapidly. A 74-year-old woman underwent an emergency incision and drainage for a deep neck infection of dental origin. She was orally intubated with a 6. 0 mm internal diameter reinforced endotracheal tube by video laryngoscope using volatile induction and maintenance anesthesia (VIMA) with sevoflurane, fentanyl ($100{\mu}g$), and succinylcholine (75 mg). During surgery, peak inspiratory pressure increased from 22 to $38cmH_2O$ and plateau pressure increased from 20 to $28cmH_2O$. We maintained anesthesia because we were unable to access the airway, which was covered with surgical drapes, and tidal volume was delivered. At the end of surgery, we found a longitudinal fold inside the tube with a fiberoptic bronchoscope. The patient was reintubated with another tube and ventilation immediately improved. We recognized that the tube was obstructed due to dissection of the inner layer.

Oronasal fistulae (ONF) could remain after surgery in some patients with cleft palate. ONF ultimately requires intraoral surgery, which may lead to perioperative airway obstruction. Tongue flap surgery is a technique used to repair ONF. During the second surgery for performing tongue flap division, the flap transplanted from the tongue dorsum to the palate of the patient acts as an obstacle to airway management, which poses a great challenge for anesthesiologists. In particular, anesthesiologists may face difficulty in airway evaluation and patient cooperation during general anesthesia for tongue flap division surgery in pediatric patients. The authors report a case of airway management using a flexible fiberoptic bronchoscope during general anesthesia for tongue flap division surgery in a 6-year-old child.

연구배경: 국내에서 굴곡성 기관지경에 의해 기도 내 이물이 확인된 성인 환자에서 흡인의 위험도에 따른 임상적 특징 및 이물 제거 방법 및 결과에 대한 보고가 없어 본 연구를 계획하였다. 방법: 1994년 12월부터 2004년 12월까지 경희대학교 부속병원에서 굴곡성 기관지경을 시행하여 기도 내 이물이 확인되었던 29명의 성인 환자를 대상으로 면밀한 의무 기록을 바탕으로 후향적 분석을 시행하였다. 결과: 14명은 흡인의 위험인자가 없었던 반면 15명은 흡인의 위험도가 높은 중추신경계 질환을 가지고 있었다. 전체 환자 중, 7명(24.1%)은 흡인에 대한 과거력이 없었다. 22명의 환자가 호흡기 증상이 확인되었는데, 기침(62.0%), 호흡곤란(44.8%), 발열(20.7%), 천명(13.8%), 흉통(10.3%) 및 객혈(0.4%) 순이었다. 흡인의 위험인자가 없는 환자의 92.8%가 증상이 발생한 반면 흡인 위험도가 높은 환자에서는 60%에서만 증상이 발생하였다(p=0.005). 또한 진단이 되기까지 증상 발생 기간이 각각 4일과 2일로 흡인 위험도가 높은 환자들에서 더 길었고(p=0.007), 3일 이내의 급성 호흡기 증상이 발생한 경우가 더 적었다(p=0.048). 6명(20.9%)의 환자가 단순 흉부 방사선에서 이상 소견이 없었던 반면 23명에서는 이물의 음영(11명), 폐렴(8명), air trapping(5명) 및 무기폐(3명) 등의 소견이 관찰되었다. 흡인의 위험도에 따른 기도 내 이물에 의한 방사선학적 특징에는 차이가 없었다. 흡인 위치로는 우측 기관지가 16예로 가장 많은 빈도를 보였고 우측 하엽 기관지가 가장 흔한 위치였다. 흡인 이물의 종류로는 치아가 11예로 가장 많은 빈도를 보였다. 흡인의 위험도가 높은 환자들에서 의학적 처기가 기도 내 이물 흡인이 발생하는 가장 흔한 경우였다. 모든 대상 환자의 기도 내 이물은 큰 부작용 없이 성공적으로 모두 제거되었으며 alligator jaw biopsy forceps이 이물 제거를 위해 가장 많이 사용되었다. 결론: 본 연구는 흡인의 위험도가 높은 환자에서는 이물 흡인의 과거력이 명확하지 않고 비전형적인 호흡기 증상을 보이는 경우가 많아 진단이 지연되거나 간과될 가능성이 높고 특히 의학적 처치 시 가장 많이 발생한다는 것을 보여주었다. 따라서 흡인의 위험성이 높은 환자에서 이물 흡인에 대한 적극적인 검사와 주의가 필요할 것으로 사료된다.

Background and Objectives: Foreign bodies of upper aerodigestive tract are common problem for primary care physicians. Delayed diagnosis or failure of removal might cause fatal problemsand complications. Therefore proper diagnosis and management is imperative. In this study, we described clinical features of upper aerodigestive tract foreign body, and analyzed efficacy of different management modality. Materials and Methods: 250 cases of foreign bodies in the esophagus and trachea, between Jan. 1998 through Jan. 2009 has been retrospectively analyzed. A total of 24 cases and 226 cases had been found each as airway foreign bodies and esophageal foreign bodies. The clinical features are described and treatment outcomes, prognosis, and rate of complications of each management modality have been compared. Results: In airway foreign bodies, ventilating bronchoscopy yielded better results, 19 success out of 19 trials than fiberoptic bronchoscopy, 3 success out of 5 trials. Hospitalization days after removal of foreign body didn't show difference between two treatment modalities, although patients who had ventilating bronchoscopy had gone through general anesthesia. And there was no complication after removal of foreign body. In esophageal foreign bodies, rigid esophagoscope yielded better results, 99% of successful removal rate, compared to the EGD, only 78% of successful removal rate. There was no difference of hospitalization days between two modalities. And complication rate was even low in patients who had done rigid esophagoscopic foreign body removal. Conclusion: In upper aerodigestivetract foreign body. Rapid diagnosis and successful foreign body removal is important. Removal by rigid scope(ventilating bronchoscope, rigid esophagoscope) revealed less failure in both airway and esophageal foreign bodies.
