The pre-treatment neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and red cell distribution width predict prognosis in patients with laryngeal carcinoma.
The aim of this study was to identify the potential prognostic roles of the preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) in patients with laryngeal squamous cell carcinoma (LSCC). 81 patients who underwent surgery for the larynx carcinoma were enrolled in the study. NLR, PLR and RDW were used as outcome measures. Local recurrence was detected in 30 (37.0 %) patients and neck lymph node metastasis was detected 6 (7.4 %) patients during follow-up period. ⋯ According to Cox regression analysis, a high PLR increases mortality 4.2 times and a high RDW 4.6 times. Although in univariate analysis MCV, RDW and tumor grade were predictors of mortality, RDW and tumor grade independent predictors were found. Further studies involving large patient groups are required.

Incidence of intraglandular lymph nodes within submandibular gland, and involvement by floor of mouth cancer.
Resection of the submandibular gland is generally undertaken as an integral component of level I neck dissection for oral cancer. However, it is unclear whether lymph nodes are present within the submandibular gland which may form the basis of lymphatic spread. Our purpose was to investigate the frequency of lymph nodes within the submandibular gland, and the incidence and mechanism of submandibular gland involvement in floor of mouth cancer. ⋯ Mechanisms of involvement were direct extension, and by an apparent novel mechanism of carcinoma growing along bilateral Wharton's ducts. Despite the high incidence of level I metastasis in floor of mouth, lymphatic metastases to submandibular gland are unlikely based on absence of intraglandular lymph nodes. We describe a previously unreported mechanism of submandibular gland involvement.

Total analysis of clinical factors for surgical success of adenotonsillectomy in pediatric OSAS.
The objective of this study is the total evaluation of most common clinical factors influencing the successful rate of adenotonsillectomy for pediatric obstructive sleep apnea syndrome (OSAS). Retrospectively, 63 pediatric patients ranged from 2 to 16 years old were included. Syndromics and patients who had received orthodontic treatment or orthognathic surgery were excluded. ⋯ Pre-operative cephalometry parameters, BMI and age did not show significant correlation with surgical success, however, pre-op AHI and tonsil size correlated with surgical success. Higher pre-op AHI value and higher tonsil grade showed higher rate of surgical success. Based on the total evaluation of clinical data, surgical success after adenotonsillectomy might be predicted by pre-op AHI severity and tonsil grade.

The effect of preoperative neutrophil, platelet and lymphocyte counts on local recurrence and survival in early-stage tongue cancer.
The aim of this study was to investigate the predictive value of preoperative neutrophil, platelet and lymphocyte counts in local recurrence and survival in the patients operated for early-stage squamous cell carcinoma (SCC) of the tongue. 57 patients who underwent surgery for early-stage (stage 1-2) SCC of the tongue were enrolled in the study. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and neutrophil × PLR value (N × PLR) were used as outcome measures. Local recurrence was detected in 11 (19.3 %) patients during follow-up period. ⋯ The relationship between NLR, PLR, N × PLR and local recurrence was statistically significant according to these cutoff values (p values 0.021, 0.020, 0.017, respectively). We suggest that NLR, PLR and N × PLR may be used to predict local recurrence, while their use in overall and disease-free survival is limited. Further studies involving large patient groups are required.

Application of xenogenic acellular dermal matrix in reconstruction of oncological hypopharyngeal defects.
Acellular dermal matrix (ADM) can be used as a new membrane substitute for repairing mucosal defects. The objective of this study is to explore the effectiveness of xenogenic acellular dermal matrix (xeno-ADM) in hypopharynx reconstruction. A total of 40 patients were treated with this surgical method to reconstruct hypopharynx in our department between February 2011 and October 2012. ⋯ All patients were successfully decannulated. The overall 3-year survival rate is 67.5 %; the 3-year disease-free rate is 47.5 %. Reconstruction of hypopharynx by xeno-ADM is proved to be a simple, safe and effective method with fewer complications.
