In this report, we describe the incidental finding of an oropharyngeal mass in a patient who presented with a chief complaint of temporomandibular pain. The patient was initially evaluated by an otorhinolaryngologist for complaints of headaches, earache, and sinus congestion. Due to worsening headaches and trismus, he was further referred for the management of temporomandibular disorder. The clinical evaluation was uneventful except for limited mouth opening (trismus). An advanced radiological evaluation using magnetic resonance imaging revealed a mass in the nasopharyngeal/oropharyngeal region. The mass occupied the masticatory space and extended superioinferiorly from the skull base to the mandible. A diagnostic biopsy of the lesion revealed a long­standing human papilloma virus (HPV­16)­positive squamous cell carcinoma of the oropharynx. This case illustrates the need for the timely radiological evaluation of seemingly innocuous orofacial pain.

The role of transoral robotic surgery in the treatment of upper aerodigestive tract tumor has expanded in recent. Since the approval of the da Vinci system, the number of transoral robotic surgery has increased significantly. The main indications of transoral robotic surgery are tumors of oropharynx, hypopharynx, and larynxs. Transoral robotic surgery is a minimally invasive surgical approach that offers surgical access to the laryngopharynx without the morbidity of open surgeries while achieving excellent oncologic and functional outcomes. The appropriate application of transoral robotic surgery is still being investigated and previous studies supports transoral robotic surgery as a viable option in the management of upper aerodigestive tract tumor.

The styloid process is a slender, cylindrical bony outgrowth located immediately in front of the stylomastoid foramen and fused to the inferior aspect of the temporal bone. The elongated styloid process is not so frequent and the styloid syndrome is a dull, nagging pain in the oropharynx, often referred to the ear and the mastoid region. The symptoms are secondary stimulation of the nerves and vessels which pass close to the tip of the process. The clinical diagnosis is certain if the elongated styloid process is palpated through the tonsillar area. Radiologic investigation give information about the length of the styloid process and medial angulation. The treatment of choice is surgical shortening of the process. Recently, the authors experienced a case of elongated styloid syndrome misdiagnosed as pharyngeal neurosis in a 28 year-old male patient.

A pulmonary actinomycosis is a chronic suppurative disease which leads to abscess formation and fibrosis it was caused by aspiration of contaminated material from to mouth or oropharynx. Recently pulmonary actinomycosis is very rare by widespread use of antibiotics. Clinically, patients with pulmonary actinomycosis initially experience nonproductive coughing and low grade fever, but pulmonary complaints can be minimal. We report a case of pulmonary actinomycosis associated with hemoptysis which was confirmed by lobectomy with a review of literature.

Food intake and swallowing are complicated and intriguing series of movements involving voluntary and involuntary activities of cranial and spinal nerves and muscles. They have two most important functions, that is, food passage from the oral cavity to stomach and airway protection. Tongue, buccinators, and hyoid bone and its muscular attachments are anatomic structures for swallowing of special interests. The swallowing process of liquid is commonly divided into oral preparatory, oral propulsive, pharyngeal, and esophageal stages according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs between eating solid food and drinking liquid.

Velopharyngeal function refers to the combined activity of the soft palate and pharynx in closing and opening the velopharyngeal port to the required degree. In normal speech, various muscles of palate & pharynx function as sphincter and occlude the oropharynx from the nasopharynx during the production of oral consonant sounds. Inadequate velopharyngeal function caused by neurologic disorder - cerebral apoplexy, regressive diseases - disseminated sclerosis, Parkinson's disease, congenital deformity - cleft palate, cerebral palsy and etc. may result in abnormal speech characterized by hypernasality, nasal emission and decreased intelligibility of speech due to weak consonant production. In our study, we constructed speech aids prosthesis - Palatal lift in acquired idiophathic VPI patient and assessed velopharyngeal function with various diagnostic instruments which can evaluate the speech characteristics objectively.

A combination of positron emission tomography (PET) with $^{18}F$-labeled fluoro-2-deoxyglucose ($^{18}F$-FDG) and computed tomography ($^{18}F$-FDG-PET/CT) has increasingly become a widely used imaging modality for the diagnosis and management of head and neck cancer. On the basis of both recent literature and our professional experience, we present a set of principles with pictorial illustrations and clinical applications of FDG-PET/CT in the evaluation and management planning of squamous cell carcinoma of the oral cavity and oropharynx. We feel that this paper will be of interest and will aid the learning of oral and maxillofacial radiology trainees and practitioners.

Velopharyngeal function refers to the combined activity of the soft palate and pharynx in closing and opening the velopharyngeal port to the required degree. In normal speech, during the production of oral consonant sounds elevation of the soft palate, along with the superior constrictor muscle, occludes the oropharynx from the nasopharynx. Inadequate velopharyngeal function caused by congenital or acquired insufficiency or incompetency may result in abnormal speech characterized by hypernasality, nasal emission and decreased intelligibility of speech due to weak consonant production. The speech aid is often helpful in improving the speech of individuals with velopharyngeal incompetency. In this article, the pathogenesis and treatment of velopharyngeal incompetence are discussed and a speech aid appliance that was constructed for the patient is described.

One of the most lethal forms of mediastinitis is descending necrotizing mediastinitis, in which infection arising from the oropharynx spreads to the mediastinum. Despite the development of computed tomographic scanning to aid in the early diagnosis of mediastinitis, the past 30 years, in large part because of continued dependence on transcervical mediastinal drainage, Although transcervical drainage is usually effective in the treatment of acute mediastinitis due to a cervical esophageal perforation, these approach in the patient with descending necrotizing mediastinitis fails to provide adequate drainage and pre-disposes to sepsis and a poor outcome. In addition to cervical drainage, aggressive, early mediastinal exploration - debridement and drainage through a subxiphoid incision or thoracotomy - is advocated to salvage the patient with descending necrotizing mediastinitis.

Malignant lymphoma is the tumor of immune system which is known as the most common nonepitheloid tumor of head and neck region. It is mainly found in the cervical, axillary and inguinal lymph node, but gastrointestinal tract, palatine tonsil, nasopharynx, oropharynx, nasal cavity and salivary glands may be involved. Primary lymphoma of the thyroid gland is an uncommon condition, comprising approximately 2% of all malignant lymphoma and 5% of all thyroid malignant neoplasms. Recently, we experienced a case of malignant lymphoma of the thyroid gland, which was histopathologically proven. So we report our findings in this patient with review of literatures.
