  • Since Carrel in 1907 reported transfer of a free jejunal segment in dog, reconstruction of the cervical esophagus and hypopharynx has been accomplished successfully with free jejunal transplantation using microvascular technique. Free jejunal graft is useful in cases of failed colonic interpositions. Three patients with benign esophageal stricture had undergone reconstruction with right colon interposition. Because of necrosis and stricture of the interposed colon, in each case the defect was reconstructed with a free jejunal graft by using microvascular technique. The postoperative course in two patients was uncomplicated, and they were able to eat general diet. Graft necrosis occurred in one patient, but she is waiting for a reoperation.

  • Synovial sarcomas are rare soft tissue malignancies arising from tendons, tendon sheaths, and bursal structures. These tumors usually develop in the extremities of adolescents and young adults. Uncommonly, these tumors may arise in the head and neck approximately 9% of all synovial sarcomas. Most common sites of head and neck synovial sarcomas are hypopharynx and surrounding structures of paranasal sinuses. However, frontal bone without involving paranasal sinus is extremely rare. We report a case of biphasic synovial sarcoma of the frontal bone discuss the clinical and pathologic features of this case with the literature review.

  • Between October 1987 and October 1990, 6 patients underwent pharyngolaryngoesophagectomy with transhiatal gastric transposition and pharyngogastrostomy for hypopharyngeal and recurred laryngeal cancer. All patients had squamous cell carcinoma and were male, with age range from 54 to 67 years. Two patients had been treated initially by chemotherapy, but the tumor had persisted. One patient had been treated by radiotherapy and operation, but tumor had recurred in hypopharynx. There was no operative death. Major complications were anastomotic leakage in three cases, wound disruption in four cases and one postoperative bleeding. Anastomotic leakage was recovered in two cases with conservative management. The average hospital day was 33 days postoperatively. We conclude that reconstruction of the pharynx and cervical esophagus with gastric transposition is one of the recommendable procedures for extensive resection of pharynx or cervical esophagus with acceptable morbidity and functional recovery.

  • Tracheoesophageal fistulation following total laryngectomy has widely been used for voice restoration, This technique make exhaled air to divert to hypopharynx where phayngoesophageal segment forms the neoglottis. Even through layngectomized patients loss the normal laryngeal adjustment for speaking, it has been known that voiced and voiceless sounds are prodused in TE phonation. Nine TE speakeres were subjected to present study designed to clarity the mechanism of neoglottic adjustment in TE phonation, Fiberoptic examination and radiologic studies were performed at all patients and EMG study was performed at 3 patients during I phonation. Fiberoptic & radiologic studies revealed the location of neoglottis, so called pharyngoesophargeal segment which was vibrated well. EMG activity increased for sound production at retropharyngeal prominence. These results indicated that neoglottic adjustment in TE phonation.

  • We describe a case of venous malformation of pyriform sinus in 63 year-old patient, discovered incidentally. Venous malformation are the most common vascular malformations to arise in the head and neck. However venous malformation of the hypopharynx in the adult papulation are rare. The author performed successfully ethanol sclerotherapy for venous malformation of pyriform sinus, so we present the case with a review of the related literatures.

  • Hypopharyngeal cancer have shown poor prognosis though various treatment modalities were developed for several decades. Therefore current trend in managing hypopharyngeal cancer is organ preservation therapy to improve patient's quality of life. Recently, surgery via robotic surgical system in genitourinary surgery improved minimal invasive technique and reduced morbidity dramatically. Hypopharyngeal cancer treatment using Transoral robotic surgery (TORS) in treating lesions of hypopharynx could reduce the morbidity and achieve organ preservation.

  • The parathyroid glands are usually located in the posterolateral area of the thyroid gland. Due to their embryologic origin, they are sometimes found in an ectopic position from the angle of the jaw to the mediastinum. However, their incidental detection in the hypopharyngeal wall is rare. Herein, we report a case of an ectopic parathyroid gland found in the hypopharyngeal wall of a 39-year old woman with no known endocrine abnormality.

  • Intubation may lead to several dental complications. Furthermore, a tooth damaged during intubation may be subsequently dislocated. In the present case, the upper primary incisor was avulsed during intubation and, unbeknownst to the anesthesiologist, displaced to the larynx. We report here on the findings and indicate appropriate treatment. Intubation for general anesthesia in children can result in tooth damage and/or dislocation of primary teeth with subsequent root resorption. Prevention is key, and thus it is critical to evaluate the patient's dental status before and after intubation. Furthermore, anesthesiologists and dentists should pay close attention to this risk to prevent any avulsed, dislocated, or otherwise displaced teeth from remaining undetected and subsequently causing serious complications.

  • Liposarcoma is one of the most common malignancies originating from human soft tissue. Because most of liposarcoma occur in the lower extremities or retroperitoneum, there are few reports about liposarcoma of head and neck region, including larynx and pharynx. Histologically, there are four types of liposarcoma, and prognosis and recurrence rate are different according to histologic subtype. Wide excision is the treatment of choice and liposarcoma hardly respond to primary radiotherapy. A 56-year-old man presented with voice change and foreign body sensation in laryngopharynx. Hypopharyngeal liposarcoma was diagnosed by surgical biopsy and performed totallaryngopharyngoesophagectomy and gastric pull-up. Here we report our experience on this case with review of literature.

  • Objectives: To investigate the airway narrowing patterns by multi-level airway pressure(MAP) monitoring during sleep and to evaluate the value of CT scan taken during waking and sleep apneic periods to identify the level of airway narrowing(LAN) in patients with obstructive sleep apnea syndrome(OSAS). Methods: Eleven patients with OSAS underwent a night polysomnography with continuous MAP monitoring by 4-sensor(placed at nasopharynx, caudal-uvula, hypopharynx, esophagus) or 2-sensor(placed at caudal-uvula and esophagus) catheter. All patients had cine CT at five levels of high retro and alatal, low retropalatal, retroglossal, epiglottis and hypopharynx during awake and sleep periods. In each patient, LAN determined by CT scan($LAN_{CT}$) during sleep apnea was compared with LAN by MAP monitoring($LAN_{MAP}$). Results: MAP monitoring showed that four patients(36%) had a single pattern of LAN while the other seven patients(64%) showed two or more different LANs in different apneic episodes. Velopharynx was the most common level of frequently observed airway narrowing during sleep apnea(63.6%). However, a single pattern of airway narrowing was more frequent(72.7%) in airway CT during sleep apnea. Velopharynx was the most common narrowest level also in apneic CT(66%). In comparing $LAN_{CT}$ with $LAN_{MAP}$, the $LAN_{CT}$ of five patients(45.5%) were high-concordant, those of another five(45.5%) low-concordant, and that of one(9%) discordant with $LAN_{MAP}$. Conclusions: Cine CT scan during the awake state or sleep apnea may not reflect the LAN correctly in OSAS because most patients showed two or more different airway narrowing patterns during different episodes of sleep apnea in each patient.
