Nasopharyngeal carcinoma (NPC) is endemic in southern China, and its incidence in Hong Kong is relatively high. Radiotherapy is the mainstay treatment for NPC due to its relatively high radiosensitivity and deep-seated anatomical position, which is not readily accessible by surgery. Although the technique of radiotherapy in NPC has been advancing and offers promising treatment outcome, complica...

PURPOSE The aim of this study was to evaluate the effect of two different concentrations (4 and 8 mg) of dexamethasone to decrease the swelling and trismus after the surgical extraction of mandibular impacted third molars. METHODS This randomized clinical trial comprised thirty (30) adult patients of both genders with no local or systemic problems, with bilateral impacted lower third molars i...

by increasing number of vessels. Salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. Salivary gland hemangioma makes up 1 % of all salivary gland tumors. Trismus resulting from parotid hemangioma is so rare. The patient was a 6-month-old boy with a huge lesion in his right parotid who referred to Shahid sadoughi hospital of Yazd, Iran. The lesion appea...

Head and neck cancers (HNC) account for 10–15% of all globally. Curative radiation therapy (RT) concurrent chemoradiotherapy (CCRT) with or without surgery are widely accepted standard treatment modalities these patients. Radiation-induced fibrosis is one the side effects treatments, it causes degeneration, inflammation, pain, atrophy masticatory muscle fibers temporomandibular joint, resulting...

Bilateral parapharyngeal abscess is a very rare condition. Placing pressure on the airway both sides increases risk of respiratory arrest. Intubation cannot be performed due to trismus caused by infection in mastication muscles, and need create an emergency can only provided invasive means. The adjacency region major vessels their branches lead massive hemorrhages since erodes vascular wall. In...

Background: Surgical extraction of impacted mandibular third molar is one of the commonest oral surgical procedures. It is frequently associated with sequelae such as postoperative pain, swelling and trismus, which is known to have an impact on the quality of life of the patients. The aim of this study was to determine the effect of a single dose of pre-operative oral dexamethasone on postopera...

BACKGROUND Lower impacted third molar surgical extraction usually causes post-surgical sequelae like pain, trismus and swelling as a result of postoperative inflammatory response. OBJECTIVE The aim of this study was to evaluate and compare the efficacy of single dose 40-mg (1 cc) of methylprednisolone acetate, injected into the masseter muscle, preoperatively one hour before the surgery or po...
