ABSTRACT

<p><b>OBJECTIVE</b>The aim of this study was to describe a new technique of combined hyoid bone and thyrohyoid membrane flap in laryngeal reconstruction after tumor resection, and to evaluate outcome.</p><p><b>METHODS</b>Six patients requiring an frontal partial laryngectomy for cancer were enrolled between September 2008 and August 2012.</p><p><b>RESULTS</b>Nasogastric feeding was initiated within 24 hours. The mean times to swallow batter, ability to drink water and removal of the nasogastric tube were 2.6, 5.5 and 6.3 days. All patients had good respiratory function. There were no deaths, and no reports of postoperative dyspnea or dysphagia. The vocal quality was satisfactory, slightly deeper and raspy, and the volume was weak when calling. The final follow-up assessment was in August 2012, and the overall mean follow-up period was 29.5months, range 14 to 47 months. Case two subsequently underwent total laryngectomy for recurrence in the paraglottic space, but there was no evidence of further tumor recurrence at the final assessment.</p><p><b>CONCLUSIONS</b>The combined muscle-pedicle hyoid bone and thyrohyoid membrane flap is a reliable graft for one-stage repair of laryngotracheal defects, providing effective repair of the mucosa and cartilage support. Vocal quality, swallowing function and ventilation after the procedure were favorable.</p>

ABSTRACT

ObjectiveTo evaluate the clinical value of infrahyoid myocutaneous flap in the reconstruction of mouth floor tissue defects. MethodsInfrahyoid myocutaneous flap was made including stenohyoid,thyrohyoid,omohyoid and the affiliated skin based on the axis of superior thyroid artery,vein and ansa cervicalis. The clinical data of 11 patients with reconstruction of mouth floor tissue defects using infrahyoid myocutaneous flap (maximum area was 8 cm × 3 cm) from Match 1993 to June 2009 were retrospectively reviewed.ResultsSeven infrahyoid myocutaneous flaps which reserved platysma branch of superior thyroid artery were all alive, while 2 patients presented epidermal necrosis of 4 un-protected patients. The follow-up period was range from 24 months to 195 months, one patient received salvage surgery for local regional lymphatic recurrence in level Ⅰ,which survived without diseases until now.The rest cases had turned out a success.No dysphagia,dysphonia,and tongue extension difficulty was reported in any patient.ConclusionInfrahyoid myocutaneous flap is one of the valuable donor sites for the reconstruction of mouth floor tissue defects after radical oncologic operations,especially for those with early stage carcinoma of the mouth floor.

ABSTRACT

OBJECTIVE@#The current study was designed to examine the expression of Skp2 gene in laryngeal squamous cell carcinoma (LSCC) and to investigate the role of Skp2 gene in tumorigenesis and progression of LSCC.@*METHOD@#FQ-PCR method was used to examined the expression of Skp2 gene in 40 LSCC and 10 normal laryngeal mucosa tissues, and relationship between its expression and clinical biological factors of patients with LSCC was analyzed.@*RESULT@#The median copy number of Skp2 mRNA expression in LSCC was 6622.54 copy/microg RNA, the median copy number of Skp2 mRNA expression in normal laryngeal mucosa tissues was 0 copy/microg RNA, there was a very significant difference between them (P < 0.01); The positive rate of Skp2 mRNA expression in LSCC and adjacent normal laryngeal tissue were 50%, 0, respectively (P < 0.01). The median copy number of Skp2 RNA expression in LSCC with cervical lymph node metastasis was 617138.4 copy/microg RNA, the median copy number of Skp2 mRNA expression in LSCC without cervical lymph node metastasis was 0 copy/microg RNA, there was a very significant difference between them (P < 0.05); The positive rate of Skp2 mRNA expression in LSCC with and without cervical lymph node metastasis were 100.00%, 35.48%, respectively (P < 0.01).@*CONCLUSION@#Skp2 gene might have relation with the cervical lymph node metastasis of LSCC. FQ-PCR is an accurate assay to detecting expression of Skp2 mRNA in patient with LSCC. The level of Skp2 mRNA expression might be a new and more accurate marker, and it can be used to predict cervical lymph node metastasis of LSCC.

ABSTRACT

OBJECTIVE The purpose of this studywas to investigate the correlation of E-cadherin(E-cad) and ?-catenin(?-cat) expression with clinical factors and prognosis in laryngeal squamous cell carcinoma (LSCC) patients. METHODS The expression of E-cad and ?-cat in 79 cases of LSCC and 10 cases of adjacent normal laryngeal mucosal tissues were evaluated by SP immunohistochemical methods. RESULTS All 10 normal samples were positive for expression of E-cad and ?-cat , The positive expression of E-cad and ?-cat in LSCC were 34.18 % and 40.51 % respectively. There was a statistically significant difference in the positive expression of E-cad and ?-cat between normal samples and LSCC (P

ABSTRACT

OBJECTIVE To investigate the correlation of S-phase kinase associated protein 2 (Skp2) and p27 expression with the clinical factors and prognosis of patients with laryngeal squamou cell carcinoma (LSCC). METHODS The expressio of Skp2 and p27 in 79 specimens of LSCC and 1 specimens of adjacent normal laryngeal mucos tissues were evaluated by SP immunohistochemist methods. RESULTS The overexpression rate Skp2 was significantly higher in LSCC(53.16 %) tha in adjacent normal laryngeal mucosa tissue (0 % (P
