Changes in health-related quality of life of oral cancer patients treated with curative intent: experience of a developing country

This study aimed to assess changes in oral cancer patients' health-related quality of life (HRQOL) and the impact of disease stage on HRQOL scores. HRQOL data were collected from seven hospital-based centres using the Functional Assessment of Cancer Therapy–Head and Neck (FACT-H&N) version 4.0 instrument. The independent samples t-test, χ2 test, and paired samples t-test were used to analyse the data. A total of 300 patients were recruited. The most common oral cancer sub-site was tongue and floor of mouth (42.6%).

Anterior open bite correction by Le Fort I osteotomy with or without anterior segmentation: which is more stable?

A retrospective cohort study was conducted to analyze the relapse rate of anterior open bite (AOB) correction comparing Le Fort I osteotomy with and without anterior segmentation. The risk factors that might contribute to relapse were also assessed. Lateral cephalograms obtained at six different times were analyzed. A total of 81 patients with AOB were recruited. Thirty-five patients underwent Le Fort I osteotomy without anterior segmentation and 46 patients underwent anterior segmentation. Le Fort I osteotomy with anterior segmentation resulted in significantly more AOB relapse when compared to that without anterior segmentation at 7 weeks postoperative (15.2% vs.

Dexamethasone injection into the pterygomandibular space in lower third molar surgery

The objective of this study was to evaluate the effects of 8mg dexamethasone injection into the pterygomandibular space on the postoperative sequelae of lower third molar surgery. A prospective, randomized, controlled, split-mouth study was designed involving 62 lower third molar extractions (31 patients). Prior to surgery, the study group received 2ml of 4mg/ml (8mg) dexamethasone injection through the pterygomandibular space following local anaesthesia; the control group received 2ml normal saline injection.

Emerging Roles of Coblation in Rhinology and Skull Base Surgery

Coblation is a technology that incorporates bipolar radiofrequency energy to ablate tissue at relatively low temperatures. Its use for sinonasal surgery is actively being investigated, including applications for turbinate reduction, sinus surgery, skull base surgery, and adenoidectomy. Potential benefits include reduction in blood loss, improved endoscopic surgical visualization, and reduction in postoperative pain. The main drawbacks are its relatively high cost, potential adverse effects on functional epithelium, and relative paucity of long-term outcomes.

Organism and Microbiome Analysis

Modern advances in DNA sequencing have allowed for the development of culture-independent techniques with application to infectious and inflammatory conditions, such as rhinosinusitis. Although paradigm-changing discoveries have resulted from molecular microbiologic methods for a number of diseases, insights provided into the role of bacteria in chronic rhinosinusitis have yet to be fully understood to the point of impacting clinical diagnosis and management. As culture-independent techniques continue to evolve and become more refined, it is likely that a better understanding will emerge of how the microbiome influences chronic rhinosinusitis pathogenesis and response to therapy.

Trends in the Use of Stents and Drug-Eluting Stents in Sinus Surgery

Stenting has long been used in the paranasal sinuses with the goals of maintaining a patent sinus cavity during the postoperative healing process and preventing restenosis from inflammation or scarring. More recently, drug-eluting stents have been introduced. Steroid-impregnated dressings and implants appear to be safe, although likely have increased systemic absorption compared with topical nasal steroid sprays and rinses. There is evidence to support the use of steroid-releasing implants in the ethmoid cavity in the postoperative period; however, more study is needed to truly define the role of these implants.
