Purpose: Various attempts of reconstruction for pharyngoesophageal defects after ablative surgery have been made to restore the function of the pharyngoesophagus. A fabricated tubed radial forearm free flap or free jejunal free flap was used when the width of remnant pharyngeal wall was less than 50% of the normal width. However there are many disadvantages such as stricture, saliva leakage and fistula formation on tubed radial forearm free flap. The jejunal free flap has the problem such as short pedicle, poor tolerance of ischemic time, wet voice and delayed transit of swallowed food due to the uncoordinated contraction. The authors studied the utility of patch-type radial forearm free flap using the remnant posterior pharyngeal wall of the hypopharynx. Methods: Retrospective reviews in Severance Hospital were made on 25 patients who underwent reconstruction surgery with patched radial forearm free flap because of the hypopharyngeal cancer between 1996 and 2005. The patients of Group I had the narrow posterior pharyngeal wall and its width was less than 3centimeters after the tumor was resected. Those of Group II had the partial pharyngectomy and the width of the remnant pharynx was larger than 3 centimeters. Results: Seven patients belonged to the group I and the flap of this group had 100% survival rate. One case of fistula and no swallowing discomfort due to stricture was reported. The Group II including 18 patients also had the 100% flap survival rate. Neither fistula nor stricture was seen but the lower diet grade was checked. Conclusion: The patch type radial forearm free flap using the remnant pharyngeal wall have the advantage of the radial forearm free flap, and furthermore this flap is the safe reconstructive method even if the width of the remnant pharyngeal wall is less than 30% of that of normal pharynx.

Background: This study aimed to investigate the relationship between pharyngeal morphology and the success or failure of blind nasotracheal intubation using standard lateral cephalometric radiography and to analyze the measurement items affecting the difficulty of blind nasotracheal intubation. Methods: Assuming a line perpendicular to the Frankfort horizontal (FH) plane, the reference point (O) was selected 1 cm above the posterior-most end of the hard palate. A line passing through the reference point and parallel to the FH plane is defined as the X-axis, and a line passing through the reference point and perpendicular to the X-axis is defined as the Y-axis. The shortest length between the tip of the uvula and posterior pharyngeal wall (AW), shortest length between the base of the tongue and posterior pharyngeal wall (BW), and width of the glottis (CW) were measured. The midpoints of the lines representing each width are defined as points A, B, and C, and the X and Y coordinates of each point are obtained (AX, BX, CX, AY, BY, and CY). For each measurement, a t-test was performed to compare the tracheal intubation success and failure groups. A binomial logistic regression analysis was performed using clinically relevant items. Results: The items significantly affecting the success rate of blind nasotracheal intubation included the difference in X coordinates at points A and C (Odds ratio, 0.714; P-value, 0.024) and the ∠ABC (Odds ratio, 1.178; P-value, 0.016). Conclusion: Using binomial logistic regression analysis, we observed statistically significant differences in AX-CX and ∠ABC between the success group and the failure group.

Background/Aims: The necessity for pharyngeal anesthesia during upper gastrointestinal endoscopy is controversial. This study aimed to compare the observation ability with and without pharyngeal anesthesia under midazolam sedation. Methods: This prospective, single-blinded, randomized study included 500 patients who underwent transoral upper gastrointestinal endoscopy under intravenous midazolam sedation. Patients were randomly allocated to pharyngeal anesthesia: PA+ or PA- groups (250 patients/group). The endoscopists obtained 10 images of the oropharynx and hypopharynx. The primary outcome was the non-inferiority of the PA- group in terms of the pharyngeal observation success rate. Results: The pharyngeal observation success rates in the pharyngeal anesthesia with and without (PA+ and PA-) groups were 84.0% and 72.0%, respectively. The PA- group was inferior (p=0.707, non-inferiority) to the PA+ group in terms of observable parts (8.33 vs. 8.86, p=0.006), time (67.2 vs. 58.2 seconds, p=0.001), and pain (1.21±2.37 vs. 0.68±1.78, p=0.004, 0-10 point visual analog scale). Suitable quality images of the posterior wall of the oropharynx, vocal fold, and pyriform sinus were inferior in the PA- group. Subgroup analysis showed a higher sedation level (Ramsay score ≥5) with almost no differences in the pharyngeal observation success rate between the groups. Conclusions: Non-pharyngeal anesthesia showed no non-inferiority in pharyngeal observation ability. Pharyngeal anesthesia may improve pharyngeal observation ability in the hypopharynx and reduce pain. However, deeper anesthesia may reduce this difference.

A 11-month-old infancy was referred for treatment of cleft palate. The patient's congenital deformities had included oronasal fistula on the soft palate and bifid uvula. Furrow double-opposing Z-plasty was performed under general anesthesia. However, postoperative bleeding developed at ward. Despite the pressure of operative wound, venous oozing continued and hemoglobin concentration and RBC were decreased (Hb: 5.5g/dL, RBC: $1.98{\times}10^6/mm^3$). The patient was pale and confused and transferred to Surgical Intensive Care Unit(SICU) We could not keep the peripheral venous line and there was a high risk of hypovolemic shock. Emergency transfusion was performed through the central femoral venous line and emergency operation for bleeding control was carried out. We explored the operation site and found bleeding point from the posterior pharyngeal wall. Electrocoagulation and surgicel packing were carried out and bleeding was stopped.

The anterior approach to the cervical spine surgery is associated with possible complications such as dysphagia, hoarseness and granuloma formation etc. Because of orthopedic metallic plates, the increasing or focal uptake pattern may be demonstrated in $^{18}F$-FDG PET/CT scan. A 67-year-old-man came to our department, complained of dysphagia during the 4 months. He underwent cervical spine surgery three years ago. The CT and MRI findings mimicked typical posterior pharyngeal wall cancer with cervical metastasis. Furthermore, the SUV in $^{18}F$-FDG PET/CT was 10.3. But he was finally diagnosed as a granuloma resulting from the metallic cervical implants. The clinical correlation and medical history should be taken into account to avoid false-positive findings in PET/CT and to avoid many erroneous diagnostic pathways.

Velopharyngeal Insufficiency(VPI); the failure of velum, the lateral wall and the posterior pharyngeal wall to separate the nasal cavity from pharyngeal cavity during speech, can be caused by congenital conditions include cleft palate, submucous cleft palate and congenital palatal insufficiency. Speech problems of VPI are characterized by hypernasality, nasal air emission, increased nasal air flow and decreased intelligibility. These speech problems of VPI can be treated with the surgical procedure, the application of temporary prosthesis and speech therapy. Biofeedback technique with Nasometer is a speech treatment method of VPI that commonly used as one component of a comprehensive procedure for improvement of speech in patients with VPI. In this article describes a case of VPI treated by biofeedback technique with Nasometer; which showed satisfactory result in nasalance and formant analysis after the speech therapy during 9 months.

Reconstruction for hypopharynx and cervical esophagus after wide resection of extensive hypopharynx and larynx cancers have been used various methods including myocutaneous flaps, gastric pull up, md jejunal or large bowel free graft. Recently, the authors had experienced hypopharynx and larynx cancers with extension to the posterior hypopharyngeal wall and thoracic esophagus. Of course, these reconstructive methods should be selected in accordance with the patient's age, physical status, extend of prim.:W lesion, and defect after on block resection, however, gastric pull up was performed in hypopharynx cancer which had skipped lesion in the thoracic esophagus and jejunal free grafts were performed in case 2, 3 which had a extended lesions to the posterior pharyngeal wall. Some complications were noted, which were successfully stabilized by conservative managements. The gastric pull up and jejunal free graft were considered suitable methods for reconstrunction of hypopharynx and cervical esophagus, however, further studies are necessary about it.

새인두흡충에 의한 인체감염 제1례를 보고한다. 환자는 56세 된 남자로서 3-4일간의 인후부 이 물감과 염증성 증상으로 이비인후과의원을 방문하여 오른쪽 인두 후벽에 흡착한 충체를 제거하였다. 충체는 Clnostoumum complanatum으로 동정되었다. 환자는 평소 담수어의 생식을 즐겼으며 의원 방문 4일전에도 낚시로 포획한 담수어를 생식한 적이 있었다. 우리 나라에서도 이 흡충에 의한 인두염의 예방을 위해 담수어의 생식에 더 깊은 주의가 요망된다고 생각된다. Clinostomum complanatum의 우리 말 이름을 새인두흡충으로 제안한다.
