ABSTRACT
Objective@#To assess the efficacy of supraclavicular artery island flap (SCAIF) for the reconstruction of hypopharynx and upper esophagus.@*Methods@#The SCAIF procedure on was used in 10 patients, including 8 with hypopharygeal carcinomas, 1 with esophageal carcinoma and neck skin invasion and 1 with hypopharyngeal leiomyosarcoma, at the Otorhinolaryngology Hospital, the First Affiliated Hospital, Sun Yatsen University between December 2015 and June 2017. The sizes of the flaps were measured in (4-8) cm×(5-12) cm. Clinical indexes such as harvesting time and survival were recorded.@*Results@#Harvesting time for SCAIF ranged from 20 to 30 minutes, averaging 26 minutes. Nine flaps survived, one flap had partially necrosis. Functional outcomes were excellent and the donor sites were direct closed without complications.@*Conclusions@#SCAIF is a versatile, reliable, and easily harvested flap, with good cosmetic and functional outcomes for reconstructing the defects of hypopharynx and upper esophagus.
ABSTRACT
OBJECTIVE@#To investigate the features and diagnosis way of small round cell tumor of nasal sinus and bases of skull.@*METHOD@#A retrospective analysis of 123 case with small round cell tumor of nasal sinus and bases of skull were carried out in our hospital in past ten year. Clinical, histological, radiological and immunohistochemical characters of these cases were studied.@*RESULT@#All cases usually complained of nasal obstruction, headache, diplopia, nasal mucus with bleeding, vision or weight loss. Expansible or infiltrative lumps were found in nasal sinus or bases of skull in radiological examination. A lot of small round cells were found in these tumors in histological pathology. At least 5-6 cell, tissue or tumor markers were examined immunohistochemically in most of cases before the final diagnosis were made. In some cases over 20 markers were examined. Five cases were carried out transmission electron microscope examination, special features such as desmosome and myofilament were found.@*CONCLUSION@#Clinical symptom, physical signs and radiological finding can supply malignant evidences of these tumors. Histological examination can make certain that they are small round cell tumors, but final diagnosis is still hard to make only by these. Immunohistochemical examination of various markers can tell the original characters of the specimen tissues, it is the key for final diagnosis. Transmission electron microscope examination is another helpful way for diagnosis.

OBJECTIVE@#To analyze the conservative management and outcomes of pharyngocutaneous fistula after total laryngectomy.@*METHOD@#Twenty-one patients with postoperative fistulas were identified and treated by conservative therapy.@*RESULT@#Different treatment were given basing on the three stages of pharyngocutaneous fistula: drainage and cleaning stage, pressure bandaging stage and healing stage. Fourteen patients (66.7%) with the conservative therapy resumed oral feeding after closure of fistula, the other 7 patients had to be cured by further operation.@*CONCLUSION@#Management basing on the stages of pharyngocutaneous fistula can achieve satisfied outcome. It can provide important information for pharyngocutaneous fistula's treatment.
