OBJECTIVETo evaluate the effect and feasibility of coblation treatment for laryngeal papilloma in adult.

METHODSA total of 18 patients with laryngeal papilloma treated by coblation from April 2008 to June 2010 was retrospectively analysed. There were 4 cases of multiple laryngeal papilloma and 14 cases of single laryngeal papilloma. All of these patients were treated with CoblatorTM Reflex #7070 under general anesthesia without tracheotomy.

RESULTSThe volumes of blood loss during surgery varied from 1 ml to 10 ml, 2 ml on average. There was no postoperative bleeding or other complications. Follow-ups ranged from 6 months to 33 months after surgery, median 18 months. Recurrence occurred 4 months and 8 months after surgery in two patients. They were treated with coblation for the second time and followed up for 4 months and 12 months respectively. Recurrence occurred again in one patient.

CONCLUSIONCoblation under suspension laryngoscope for laryngeal papilloma in adult was an ideal way due to less bleeding and less damage.

OBJECTIVETo evaluate the effect of endoscopic surgery using the low-temperature plasma radiofrequency for nasal inverted papilloma. Methods In a retrospective study, clinical data of 8 patients underwent endoscopic surgery were analyzed since July 2008. Tumor stage according to Krouse was T1:1, T2:6, T3:1, T4:0, respectively. T1 and T2 lesions were completed excised using the low-temperature plasma radiofrequency, T3 lesions were excised using microdebrider combined with plasma radiofrequency.

RESULTSThe average blood loss was about 20 ml, with the exception of one patients with recurrent nasal inverted papilloma about 200 ml. Shorter operative time, minimal postoperative pain, epithelization of nasal cavity was seen 2 months postoperatively. There were no complications. All patients were followed-up for 2-6 months, with no recurrence.

CONCLUSIONSSurgical treatment of nasal inverted papilloma using low-temperature plasma radiofrequency had following advantages: less blood loss, complete en bloc tumor resection, mild injury, short surgery time, mild postoperative pain. In summary, low-temperature plasma radiofrequency is a minimally invasive treatment for nasal inverted papilloma.

OBJECTIVETo establish whether Coblation is a suitable modality for removal of early glottic carcinoma.

METHODSFourteen patients with early glottic carcinoma (Tis-T2) without lymph node metastasis underwent resection of laryngeal cancer lesions using transoral endoscopic coblation (TEC), without pre- or post-operative radiotherapy and chemotherapy.

RESULTSNo severe complication such as bleeding and dyspnea occurred in the cases. Only mild postoperative pain happened to the patients. All patients could eat and pronounce on the surgery day. With following-up of 25 - 37 months, no recurrence was observed in 13 cases. One case, with poorly differentiated squamous cell lesion in the anterior commissure invading subglottic, recurred 3 months postoperatively. The patient received the re-resection of laryngeal lesion by coblation, but another recurrence happened to the patient 6 months postoperatively, and then was cured by partial laryngectomy, with recurrence-free survival 21 months postoperatively.

CONCLUSIONThe observation suggests that transoral endoscopic coblation is a reliable and safe modality for the resection of early glottic carcinoma.

To explore the new method of discriminating Astragali Radix and Hedysari Radix by using PCR amplification of specific alleles, 30 samples of the different Astragali Radix materials and 28 samples of Hedysari Radix were collected. The total DNA of all samples were extracted, trnL-trnF sequence from Astragali Radix and Hedysari Radix was amplified by PCR and sequenced unidirectionally. These sequences were aligned by using Clustul W. Primer was designed and the PCR reaction systems including annealing temperature, dNTP, etc were optimized. All samples were amplified by PCR with specific primer, DNA from Astragali Radix would be amplified 136 bp, whereas PCR products from all of Hedysari Radix were 323 bp. This method can detect 10% of intentional Hedysari Radix DNA into Astragali Radix. PCR amplification of alleles can be used to identify Astragali Radix and Hedysari Radix successfully and is an efficient molecular marker for authentication of Astragali Radix and Hedysari Radix.

OBJECTIVETo introduce a new surgical technique for the treatment of bilateral vocal cord paralysis.

METHODSTwenty-nine patients with bilateral vocal cord paralysis treated in Dalian Municipal Central Hospital between 2008 and 2012 were retrospectively studied. Coblation assisted arytenoidectomy was performed in all cases. The pre and postoperative glottic measurement and vocal acoustic parameters were analyzed.

RESULTSAll patients were decanulated 1 week after operation. Three months later, the mean glottic area increased from (21.9 +/- 4.7) to (40.3 +/- 5.2) mm2 (t = 5.74. P < 0.05); the width of maximal glottic chink increased from (1.47 +/- 0.37) to (4.82 +/- 0.54) mm (t = 6.24, P < 0.05). Twenty-six patients (89.7%) satisfied with the voice quality. Acoustic parameters (F0, jitter, shimmer) were no significant difference (P > 0. 05) , but there was a significant difference in maximum phonation time (P < 0.05). During three months to 3.5 years follow-up, the patients had a stable airway and effective phonation.

CONCLUSIONSEndoscopic coblation assisted arytenoidectomy is a new surgical method for the treatment of patients with bilateral vocal cord paralysis, which is efficient, minimally invasive and safe.

OBJECTIVETo evaluate the effect of endoscopic surgery using the low-temperature plasma radiofrequency for nasal hemangioma.

METHODSClinical data of 15 patients treated between October 2007 and October 2009 under endoscopic surgery using the low-temperature plasma radiofrequency were retrospectively studied.

RESULTSAll tumors in 15 patients were completely removed. The blood loss was 1 - 150 ml and the average blood loss was about 15 ml, only gelatin sponge was used to protect the wound after operation. There was no additional packing to stop bleeding. No complications were seen. The patients had mild postoperative pain. All patients were followed-up from 2 months to 2 years, no recurrence was found.

CONCLUSIONSEndoscopic surgery using low-temperature plasma radiofrequency for nasal hemangioma has following advantages such as simplicity, minimal invasion and so on. It is a viable surgical method for the treatment of nasal hemangioma.

OBJECTIVETo evaluate the relationship between the expression of monocyte chemotactic protein 1 (MCP-1) and vascular endothelial growth factor (VEGF) in nasal polyp (NP) tissues and the role of MCP-1 in the formation of nasal polyps.

METHODSForty nasal polyp tissues obtained from NP patients were used to detect the expression of MCP-1 and VEGF at the levels of protein and mRNA by immunohistochemical and in situ hybridization assay. Twenty-five inferior turbinate (IT) samples obtained from chronic rhinitis patients were used as control.

RESULTSThe expression of MCP-1 and VEGF was higher in NP tissue than in IT at protein and mRNA levels (P <0.01). The expression of these two cytokines was positively correlated(r = 0.871, P <0.05).

CONCLUSIONSMCP-1 and VEGF were involved in the formation of nasal polyps.
