Conclusions: The efficacy of uvulopalatopharyngoplasty (UPPP) can be achieved without application of an apposition suture of the palatopharyngeal arch and the palatoglossal arch.
Objective: To compare the outcomes of two different methods of pharyngeal cavity reconstruction in UPPP.
Methods: Forty-eight patients with obstructive sleep apnoea syndrome (OSAS) underwent UPPP (uvula-preserving). A classical pharyngeal cavity reconstruction was performed in 24 patients in group one, with plastic suture of the inferior nasopharynx and exposure of the tonsillar fossa in 24 patients in group two. The parameters evaluated were the subjective symptom score, the Epworth Sleepiness Scale (ESS), and polysomnography result. The mean operating times and complications of the post-operative pharyngeal cavity were investigated.
Results: No significant difference was observed in surgical success (p = 0.54), subjective syndromes (snoring, sleep apnoea, morning headache, daytime sleepiness) (p = 0.16, 0.36, 0.79 and 0.52), ESS (p = 0.41), apnoea-hypopnoea index (AHI) (p = 0.32), and minimum SaO2 (p = 0.13) between the two groups. In group one, the mean operating time was 54.72 ± 6.52 min, 11 suture dehiscence (45.8%), and five scar hypertrophy of the pharyngeal wall (20.8%) were observed post-operatively; while in group two was 38.78 ± 5.75 min, no suture dehiscence resulting from suture cutting of tissue, three scar hypertrophy were observed (12.5%).

Purpose: The objective of this study was to explore the performance of a predictive model for swallowing-induced breakthrough pain established using a redefined delineation method based on the common occurrence sites of radiation-induced oral mucositis (RIOM) in locally advanced nasopharyngeal carcinoma (NPC).
Methods And Materials: A total of 208 patients with locally advanced NPC were included in the study cohort, and the test cohort consisted of 88 patients. The oral mucosa structure was contoured using oral cavity contour (OCC), mucosal surface contour (MSC), and oral-pharyngeal mucosa (OPM) methods, and relevant dosimetric parameters were collected.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.
Methods And Materials: A total of 209 patients participated in the study.

Objectives: The aim of this study is to estimate the economic burden of oral cancer in Australia from the societal perspective.
Methods: The population consisted of the prevalence of lip and oral cavity cancer, and other lip, oral cavity, and pharynx cancers for ages 40 years and older. Healthcare costs of oral cancer were estimated using 2019-2020 Australian Disease Expenditure Data.

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.
