RESUMEN
Introduction: The temporomandibular joint is a complex synovial joint in the body. It is the area in which the mandible articulates with the cranium. The temporomandibular joint space is located between the articular eminence and the glenoid fossa of the temporal bone at the base of the skull and the condylar process of the mandible. This interarticular space is divided into superior joint space (1.2 ml) and inferior joint space (0.9 ml) by the articular disc. The purpose of this study is to detect and evaluate the variations in the temporomandibular joint space among patients having temporomandibular joint disorders. Materials and Methods: In this retrospective study, 60 magnetic resonance imaging scans were evaluated at King Faisal Specialist Hospital in Riyadh, Saudi Arabia, between the years 2006 and 2016. Measurements were done in sagittal view in three areas: anterior, central, and posterior areas. However, coronal view readings were recorded in two different areas: medial and lateral joint spaces. All measurements were recorded at the highest point of the condyle that is perpendicular to the opposing bone. The SPSS program was used for statistical analysis. Results: The central joint space values were higher than the anterior and posterior joint spaces in both coronal and sagittal views. We also found that joint spaces among male patients were higher than female patients (right side P=0.015 and left side P=0.006). It is worth mentioning that the number of temporomandibular joint disorder female patients was more than the number of male temporomandibular joint disorder patients (52 females versus 24 males). Additionally, patients who were older than 55 years old had wider joint spaces than patients who were younger than 25 years old. Conclusion: The central joint space value was the highest among the other joint spaces on both views of magnetic resonance imaging, and the values of joint spaces among males were larger than those of females on sagittal magnetic resonance imaging. Patients with elderly temporomandibular joint disorders showed larger joint spaces than young patients. This study spotlights the importance of magnetic resonance imaging evaluation in temporomandibular joint disorder patients for a better understanding of the clinical evolution of temporomandibular disorders.

OBJECTIVE: To evaluate the barriers faced by patients with nonsyndromic orofacial clefts (NSOFC) throughout their treatment course in Saudi Arabia. DESIGN: A cross-sectional study. SETTING: Eleven different governmental health care centers across Saudi Arabia. Patients: Records of pediatric patients with NSOFC. INTERVENTIONS: A questionnaire with multiple validation stages was designed to assess the barriers in care of these patients through telephonic interviews with the parents or guardians of patients with NSOFC. MAIN OUTCOME MEASURES: We identified 3 care-barrier-related factors: (1) geographic accessibility, (2) appointment availability and accessibility, and (3) scheduling-related barriers. RESULTS: Overall, 240 participants of both sexes, with orofacial cleft of various types and with various demographic characteristics (residence, family monthly income, and caregiver level of education) were included. The highest mean score of care barriers was reported for scheduling-related barriers. Overall, 186 individuals reported sometimes/often not receiving the required medical care for the following reasons: scheduling difficulties (89%; 37.1%), prolonged waiting room time (40%; 16.7%), and transportation difficulties (36%; 15.0%). A linear regression showed that parents cited late appointments as the main reason for patients with NSOFC not receiving adequate medical care. Care-barrier factors were significantly related to gender (P = .035), patient age (P < .001), place of residency (P < .001), and caregiver's level of education (P = .015). CONCLUSIONS: Gaps in the health care system directly related to common care barriers need to be addressed to ensure adequate care for patients with NSOFC.

PURPOSE: Approximately 35% to 60% of all patients with head and neck cancer are malnourished at the time of their diagnosis because of tumor burden and obstruction of intake or the anorexia and cachexia associated with their cancer. The purpose of this article is to provide a contemporary review of the nutritional aspects of care for patients with head and neck cancer. MATERIALS AND METHODS: A literature search was performed in Medline, Cochrane, and other available databases from 1990 through 2012 for the clinical effectiveness of nutritional support, treatment modalities, and methods of delivery in relation to patients with head and neck malignancies. Human studies published in English and having nutritional status and head and neck cancer as a predictor variable were included. Randomized controlled trials, meta-analyses, prospective clinical studies, and systemic reviews were selected based on their relevance to the abovementioned subtitles. The resultant articles were analyzed and summarized into the definition, impact, assessment, treatment, and modes of administration of nutrition on the outcome of patients with head and neck cancer. RESULTS: Articles were reviewed that focused on the etiology and assessment of malnutrition and current nutritional treatments for cancer-induced anorexia and cachexia. Two hundred forty-eight articles were found: 2 clinical trials, 10 meta-analyses, 210 review studies, and 26 systematic reviews. Because of the lack of prospective data, a summative review of the conclusions of the studies is presented. CONCLUSION: Nutritional interventions should be initiated before cancer treatment begins and these interventions need to be ongoing after completion of treatment to ensure optimal outcomes for patients. A nutritional assessment must be part of all comprehensive treatment plans for patients with head and neck cancer. Alternative medical interventions, such as immune-enhancing nutrients or anticytokine pharmaceutical agents, also may be effective as adjuvant therapies, but more research is needed to quantify their clinical effect.

OBJECTIVE: The objective of the study is to determine the role of Lateral Pterygoid Muscle LPM in the articular disc displacement ADD, which is considered controversial due to the variations in the pattern of insertion of the Superior Lateral Pterygoid Muscle SPLM. BACKGROUND: It is well understood that the superior head of the lateral pterygoid muscle has only a single insertion pattern among individuals, in which the muscle is attached to the articular disc and capsule. However, recent findings in many studies have shown a noticeable variation in the insertion pattern of the upper LPM. METHODS: MRI examinations were collected at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia. Scans of 61 patients (41 females, 20 males; mean age 33 years old) with symptoms of temporomandibular dysfunction were reviewed retrospectively. The direction of their articular disc displacement was evaluated through sagittal and coronal views in both open and closed mouth positions. RESULTS: There was no statistical significance found between the LPM attachment types and TMJ disc position. The chi-square test also showed no significant difference between the type of LPM attachment and the condylar location. Forty-five percent of the articular discs were located between the articular eminence and the glenoid fossa. The majority of the disc displacement was in the anterior direction. CONCLUSION: There was no statistically significant association found between the type of LPM attachments and the direction of disc displacement.

OBJECTIVE: The aim of this article is to review the mechanism of action, physiological effects, and therapeutic applications of botulinum neurotoxins in the head and neck area. STUDY DESIGN: An extensive literature search was performed using keywords. The resulting articles were analyzed for relevance in four areas: overview on botulinum neurotoxins, the role of botulinum neurotoxins in the management of salivary secretory disorders, the role of botulinum neurotoxins in the management of facial pain, and the role of botulinum neurotoxins in head and neck movement disorders. Institutional review board approval was not needed due the nature of the study. RESULTS: Botulinum neurotoxin therapy was demonstrated to be a valuable alternative to conventional medical therapy for many conditions affecting the head and neck area in terms of morbidly, mortality, and patient satisfaction with treatment outcomes. CONCLUSION: Botulinum neurotoxin therapy provides viable alternatives to traditional treatment modalities for some conditions affecting the head and neck region that have neurological components. This therapy can overcome some of the morbidities associated with conventional therapy. More research is needed to determine the ideal doses of botulinum neurotoxin to treat different diseases affecting the head and neck regions.
RESUMEN
Oral submucous fibrosis is a chronic debilitating disease characterized by gradually increasing fibrosis of the oral cavity and pharynx, mainly the buccal mucosa, resulting in trismus. The highest incidence of oral submucous fibrosis is seen in South India due to various deleterious habits. In spite of the numerous medical modalities employed in the management of oral submucous fibrosis, occasionally surgical intervention becomes inevitable. Various surgical approaches have been used to reconstruct the surgical defects following excision of fibrous bands. Full thickness skin grafts have been described in the literature with variable outcomes. In the present study a 38-year-old male presented with severe oral submucous fibrosis of the buccal mucosa, which was successfully treated and reconstructed using full thickness skin graft with stable functional result after one year of treatment. An integrated review of the literature regarding etiology, histopathology, diagnostic, and treatment modalities of the disease follows.
RESUMEN
Pilomatrixoma, also known as pilomatricoma, is a benign tumor that originates from the matrix of the hair root. It usually presents as a single, slow-growing subcutaneous or intradermal firm nodule with a general size of less than 3 centimeters (cm) in diameter. However, giant pilomatrixomas (more than 5 cm) have been reported infrequently. It is more common in females and usually presents during the first two decades of life (60%) as an asymptomatic, mobile, hard, elastic mass. Most of the cases are benign and affect the face. The authors report a rare case of a giant pilomatricoma of the cheek and discuss the surgical management of these lesions, histopathological findings, and review of the literature.
