1. Objective To explore the possibility of partial laryngectomy for T3 glottic carcinoma and selection of reconstruction methods.

2. Objective:To study the reconstruction methods after vertical partial laryngectomy for glottic carcinoma of the larynx.

3. Objective To observe the appliance of different partial laryngectomy in the treatment of laryngeal cancer.

4. Conclusion Subtotal laryngectomy with preservation of arytenoid cartilage is recommended for T 3 laryngeal cancer.

5. It was concluded that partial laryngectomy is preferable choice for the treatment of glottic carcinoma.

6. Objective Supraglottic laryngectomy with or without one arytenoid is a functional laryngectomy suitable for treatment of epiglottic squamous carcinoma.

7. Conclusion The partial laryngectomy was safe and beneficial to some patients with laryngeal cancers.

8. Objective : To study the methods of vertical laryngectomy and laryngeal function reconstruction.

9. Methods The whole organ serial section of 68 total or partial laryngectomy and hypopharyngectomy specimen of pyriform sinus carcinoma were histopathologically studied.

10. Methods: Reconstruction of larynx by the epiglottis cartilage was performed in 32 patients after partial laryngectomy.

11. To investigate the incidence[http://Sentencedict.com], treatment and relative factors of pharyngocutaneous fistula ( PCF ) after total laryngectomy ( TL ) .

12. Conclusion: Epiglottis is one of the ideal material in laryngoplasty after the partial laryngectomy.

13. Objective To evaluate the long term therapeutic effect of vertical partial laryngectomy using reconstruction of modified sternohyoid muscle flap.

14. Objective To investigate the clinical relevant factors causing laryngeal stenosis scar after vertical partical laryngectomy.

15. Objective To analyze the application effects of pectoralis major myocutarleous flap (PMMW) to the repair of stomal recurrence after laryngectomy (SRAL).

16. Objective:To observe the appliance value of uni-pedicled sternohyoid myofascial flap in the reconstruction of vocal cord after partial laryngectomy .

17. To observe the voice rehabilitation of the patients received extended partial laryngectomy door muscle skin flap.

18. Objective: To study the influence of amputating cricopharyngeal muscle and unilateral pharyngeal constrictor after total laryngectomy on vocal restoration.

19. Objective To explore the related factors to pharyngocutaneous fistula after total laryngectomy.

20. Methods Included in this study were 21 cases glottic carcinoma and received vertical vertical partial laryngectomy.

21. Methods A questionnaire survey was conducted in 69 patients with laryngeal cancer after total laryngectomy.

22. Objective:To study the effect of anterior commissure reconstruction following partial vertical laryngectomy in case of postoperative laryngeal stricture.

23. To explore a new technique to prevent and treat tracheostomal stenosis ( TSS ) after total laryngectomy.

24. Conclusion: The technique of brim shape epiglottis plasty had avoid aspiration of food and also improved function of speech and swallowing for total laryngectomy patients.

25. Objective To study laryngopharyngeal anastomosis and fixing methods of supracricoid laryngectomy with reconstruction of functions in lightening aspiration and increasing decannulation rate.

26. Objective : To study the application and clinical significance of autotransfusion hemodilution in laryngectomy.

27. Objective:To reconstruct the laryngeal phonatory function under secondary total laryngectomy.

28. Methods:Among them, 19 cases were given laryngiofission combined with cordectomy(sentencedict.com), 37 for vertical partial laryngectomy and 7 for horizontal partial laryngectomy.

29. Methods : Tracheostomy with and without nickel titanium shape memory alloy stent was performed following total laryngectomy.

30. To investigate the factors affecting the incidence of positive surgical margin in partial laryngectomy.
