[Unilateral polyp originated from nasal septum: a case report].

Most polyps were originated from the contact areas of uncinate process, the middle turbinate or the ethmoid infundibulum. Polyp originated from nasal septum is extremely rare. We report a rare case of a 44-year old woman with unilateral polyp of nasal septum.

[Research progress of transoral robotic surgery in oropharyngeal cancer].

When it comes to the treatment of oropharyngeal cancer, the recurrence rate is high after radiotherapy, chemotherapy or open surgery. Transoral robotic surgery is a relatively new surgical therapy in oropharyngeal cancer, which can promote the development of minimally invasive surgery of oropharyngeal cancer. In this study, we reviewed flap reconstruction techniques of transoral robotic surgery, outcomes, contraindications,advantages and disadvantages.

[The impact of laser treatment for postoperative different vocal functions in early laryngeal cancer: network Meta-analysis].

Objective:To evaluate the impact of postoperative vocal different functional characteristics with laser treatment for early laryngeal cancer.Method:Computer searching the major medical-related databases: PubMed, Web of Science and Embase, searching and screening by two staff members at the same time to read the relevant literatures, extraction of data and research related to the purpose from the selected literature. Using Stata 14.0 software analysis the extracted data with Bayesian network Metaanalysis, get the laser surgery of early laryngeal cancer effects of different voice characteristics of vocal cord.Result:A total of nine articles was included finally according through the necessary conditions, statistical analysis results showed that early laryngeal laser surgery can significantly reduce GRABS and VHI assessment score.Conclusion:Laser treatment of early laryngeal cancer could reduce VHI and the GRABS assessment score postoperatively, improve overall postoperative vocal cord function and the quality of life of patients after surgery, but not in the early post-operative function and physiology in vocal function.

[Double-way endoscopic surgery in a patient with cystic degeneration of maxillary sinus ossifying fibroma: a case report].

Ossifying fibroma is a rare benign osteogenic neoplasm arising from undifferentiated cells of the periodontal ligament and with a potential to form fibrous tissue, cementum and bone, which is usually in molar area of the mandible, predominantly seen in young girls. And ossifying fibroma poses diagnostic and therapeutic difficulties due to their clinical, radiological and histological variabilities. We report a rare case of an 18 year old girl with cystic degeneration of ossifying fibroma in maxilla which is an uncommon site of occurrence.

[Progress of surgical treatment for T1a glottic carcinoma].

T1a glottic laryngeal carcinoma is early laryngeal cancer,involving unilateral vocal cord. T he main surgical treatments are transoral laser surgery,open surgery,transoral robotic surgery and radiofrequency ablation technique. In this paper,progress of surgical treatment for T1a glottic carcinoma were reviewed.

[Exploration of transoral robotic surgery in the treatment of pediatric obstructive sleep apnea-hypopnea syndrome].

Transoral robotic surgery (TORS) is a relatively new technique in the treatment of pediatric obstructive sleep apnea-hypopnea syndrome, which has been shown to be safe and feasible. TORS provides a minimally invasive, visualization method, which brings an unprecedented breakthrough in the treatment of pediatric obstructive sleep apnea-hypopnea syndrome. In this paper, the application and development prospect of TORS in the treatment of pediatric obstructive sleep apnea-hypopnea syndrome will be reviewed.

[Advancement of salvage surgery for recurrent head andneck squamous cell carcinoma].

The treatment options and prognosis of recurrent head and neck squamous cell carcinoma are largely determined by site, extent of disease,and previous treatment. Salvage surgery represents the primary curative option when recurrent head and neck squamous cell carcinoma is resectable. The common factors that affect the prognosis of patients undergoing salvage surgery include surgical resection margin pathology, radiation therapy, advanced initial and recurrent tumor stage, and presence of concomitant neck disease. This paper reviewed the advancement of salvage surgery for recurrent head and neck squamous cell carcinoma.

[Application progress of transoral robotic surgery in treatment of laryngeal cancer].

Transoral robotic surgery(TORS) with the Da Vinci robot has been used for the removal of laryngeal cancer,which can improve functional and aesthetic outcomes without worsening survival. We reviews the composition of the robotic surgical system, unique advantages, potential applications and limitations of existing solutions and prospects in Surgery for laryngeal cancer.Major technical improvements are expected. Smaller, more ergonomic, new-generation robots adapted to the head and neck will probably be available in the near future.
