To explore the value of nasal endoscopy assisting combined with transoral approach in resection of the carcinoma of the palate with the nasal cavity and sinuses invaded. A retrospective analysis of 21 patients with a primary malignant tumors of the palate was performed. Preoperative nasal endoscopy and CT and MRI scan showed that the primary tumors invading the nasal cavity and sinuses in all patients or skull base with varying degrees. All patients were treated by nasal endoscopic assisting combined with transoral approach. Postoprational adjuvant radiotherapy or concurrent chemoradiotherapy was performed according to pathological types and clinical stage. Postoperative complications, all-tumor resection rate, local control rate and 5-year survival rate were analyzed statistically. The combined approach was successfully performed in all patients. En bloc resection was carried out in 18 patients by this combined approach and surgical margins were free of carcinoma. The median follow-up period was 60 months. All patients had good nasal ventilation function and no epiphora in postoperation, and the overall local control rate of primary site was 85.7%, overall 5-year survival rate was 76.2%. Nasal endoscopy assisting combined with transoral approach is an effective method for the resection of palate malignant tumors invading the nasal cavity and sinuses. It is convenient for en bloc resection and local control of primary lesions. It is beneficial to preserve the function of nasal cavity and sinuses, which is in line with the principle of functional surgery.

In this study, we examined the correlation between anatomical dimensions, spray administration parameters, pressure drop across 40 pediatric nasal cavities, and in vitro posterior drug delivery (PDD) using Nasacort ALLERGY 24HR and FLONASE SENSIMIST nasal suspensions sprays, with different nozzle and actuation designs. The importance of each parameter and their interaction in the outcome (PDD) was evaluated. To do so, initially we measured anatomical and administration-related parameters, and the pressure drop of each cavity.

Purpose: The greater palatine foramen (GPF) represents the inferior opening of the greater palatine canal and is located posterolaterally on both sides of the hard palate. The aim of this study is to morphometrically characterise the GPF and to determine its anatomical relationships in a Portuguese population.

Methods: A retrospective study was performed based on the clinical records which included all permanent teeth erupted and a cone beam computed tomography (CBCT) of the entire maxilla.

Role of nasal microbiota in regulating host anti-influenza immunity in dogs.

Microbiome

January 2025

Joint International Research Laboratory of Animal Health and Food Safety, College of Veterinary Medicine, Nanjing Agricultural University, Nanjing, China.

Background: Numerous studies have confirmed a close relationship between the pathogenicity of influenza and respiratory microbiota, but the mechanistic basis for this is poorly defined. Also, the majority of these studies have been conducted on murine models, and it remains unclear how far these findings can be extrapolated from murine models to other animals. Considering that influenza A virus is increasingly recognized as an important canine respiratory pathogen, this study investigated the cross-talk between nasal and lung tissues mediated by microbes and its association with influenza susceptibility in a beagle dog model.

Enhanced Nasal-to-Brain Drug Delivery by Multivalent Bioadhesive Nanoparticle Clusters for Cerebral Ischemic Reperfusion Injury Protection.

Acta Biomater

Following cerebral ischemia, reperfusion injury can worsen ischemia-induced functional, metabolic disturbances, and pathological damage upon blood flow restoration, potentially leading to irreversible harm. Yet, there's a dearth of advanced, localized drug delivery systems ensuring active pharmaceutical ingredient (API) efficacy in cerebral protection during ischemia-reperfusion. This study introduces a multivalent bioadhesive nanoparticle-cluster, merging bioadhesive nanoparticles (BNPs) with dendritic polyamidoamine (PAMAM), enhancing nose-to-brain delivery and brain protection efficacy against cerebral ischemia-reperfusion injuries (CIRI).

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.

Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.
