Proliferative verrucous leukoplakia is a rare form of leukoplakia with a high rate of malignant transformation. It necessitates high clinical suspicion, to include a lifetime of close follow-up and repeat biopsies by a health care provider well versed in oral carcinoma.

Delivery of irrigant to maximally operated sinus cavities is variable and highly dependent on the method of nasal delivery. Use of these systems should be tailored appropriately for the desired effect.

Guidewire insertion in this study was noted to frequently create a false passage during maxillary sinus ostial dilation. After balloon dilation, irrigant penetration was increased into the sphenoid sinus for heavy and mist irrigators whereas the maxillary sinus had diminished irrigant penetration for heavy and NetiPot irrigators.

The addition of surfactant to saline irrigation improves ostial penetration in undissected and undiseased cadavers. This has practical implications for unoperated patients seeking care for sinus-related symptoms in that we have now described a method for improving topical treatment of target sinus mucosa prior to surgical intervention.

POSTERSsuturing the tracheal cartilage to sternoclavicular joint. The complication rate and PCF rate were analyzed.Results: Salvage surgeries were undergone in 36 patients between 2001 and 2008. The wound complication rate was 30.5%. The incidence of PCF was 22.2%. In the chemoradiation group, 3 out of the 5 PCF cases suffered severe bleeding. Since 2008 salvage surgery was performed in 18 patients. The wound complication rate was 28% and PCF rate was 5.5%. We had no lethal complication, such as carotid rupture. Conclusion:We could not reduce the complication rate because the complications of flap were increased. However, we could reduce the PCF rate and lethal complications using additional surgical techniques. We must improve the surgical techniques to reduce the risk of complications in salvage pharyngolaryngeal surgery in the era of organ preservation therapy.Objective: Understand local, nodal, and distant cure rates and the prognostic value of [18F]Fluorodeoxyglucose positron emission tomography (PET-CT) after chemoradiation (CRT) for advanced oropharyngeal squamous cell carcinoma (OPSCC). Propose a potential algorithm for surveillance PET-CT based on patient history.
