INTRODUCTION: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy in the literature on this subject. MATERIALS AND METHODS: A cross-sectional study was performed in patients who presented to Qaem Medical Center with parotid masses and who were candidates for parotidectomy between June 2013 and January 2015...

Ultrasonography is the first imaging method applied in the case of diseases of the salivary glands. The article discusses basic mistakes that can be made during an ultrasound examination of these structures. The reasons for these mistakes may be examiner-dependent or may be beyond their control. The latter may include, inter alia, difficult conditions during examination (technical or patient-related), similarity of ultrasound images in different diseases, the lack of clinical and laboratory data as well as the lack of results of other examinations, their insufficient number or incorrectness...

Major salivary gland (SG) ultrasonography (US) represents a noninvasive, nonirradiating imaging modality for evaluation of the major SGs in the diagnosis and follow-up of primary and secondary Sjögren syndrome. Structural changes can be visualized as hyperechogenic and hypoechogenic areas, inhomogeneity, and altered echogenicity in general. The reliability of SG-US is poorly investigated, and the definition of US abnormalities varies in previously published studies. Recent studies have shown correlations between SG-US findings and focus score in the minor SGs; however further studies are needed to validate a US criterion in updated classification/diagnostic criteria...

Diagnosis of midline neck swellings may give a myriad of options, ranging from ranula, thyroglossal duct cyst, cystic hygroma, cystic lymphangioma, epidermoid, dermoid and teratoid cysts to benign or malignant neoplasms of the mucosa or salivary glands and also rare skin appendage tumours like pilomatricoma or pilomatrix carcinoma. Various pitfalls are encountered in diagnosing these midline swellings as most of the features are overlapping. Careful history and examination have to be complemented with other diagnostic aids such as conventional radiography, ultrasonography, aspiration cytology and computed tomography to arrive at a correct diagnosis...

INTRODUCTION: Pleomorphic adenoma is a rare benign salivary gland neoplasm in children, which can be treated by simple excision. This tumor is rarely included in the differential diagnosis of solid submandibular masses in children. In the neonates, congenital pleomorphic adenoma usually presents in the nasopharynx. Surgical excision is the treatment of choice and recurrence is not expected. We report what appears to be the first case of congenital pleomorphic adenoma in the submandibular region in a one-day-old newborn...

In recent years, salivary gland ultrasonography (SGUS) has emerged as a promising tool for the diagnosis and prognostic stratification of patients with primary and secondary Sjögren's syndrome. Several studies have emphasized that salivary ultrasonography could be a highly specific tool for the diagnosis of the disease. However, before it can be used in daily clinical practice the SGUS procedure needs standardization and validation in larger disease-control groups. In this review we provide an update on the role of SGUS in the diagnostic algorithm of primary Sjögren's syndrome...

OBJECTIVES: Botulinum neurotoxin type A (BNT-A) intrasalivary gland injections in patients with neurological disorders have been known to effectively treat hypersalivation. However, oral health can be compromised with increasing the dose. The aim of this study was to find out the therapeutic effect of low-dose, ultrasonography-controlled BNT-A injections into the bilateral parotid and submandibular glands on oral health in the treatment of sialorrhea. MATERIAL AND METHODS: Twenty patients diagnosed with Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and other neurological disorders, including stroke or birth trauma, received BNT-A injections with salivary tests before and 1 month after the injections...

Salivary neoplasms are relatively infrequent entities that account for only 4% of tumors of the head and neck. Although slow-growing lesions of the preauricular area and submandibular space are often confused with sebaceous cysts, lymph nodes, or lipomas by the non-otolaryngologist, otolaryngologists-head and neck surgeons recognize that all preauricular and submandibular masses should be considered a salivary neoplasm until proven otherwise. Surgery remains the treatment of choice for benign salivary gland neoplasms; however, techniques continue to evolve in order to preserve salivary function and reduce surgical morbidity...

The trend in modern salivary calculi surgery is toward minimally invasive procedures because these benign conditions do not warrant open salivary gland surgery. Since ultrasonography is readily available, highly specific, noninvasive, and cost-effective, we have used an ultrasonography-guided technique for patients with parotid gland calculi, as both a diagnostic and a therapeutic tool for calculi removal, thus avoiding the morbidity of open surgery. We describe a case in which we used this novel technique for the peroral removal of multiple parotid calculi in a 29-year-old man...

BACKGROUND: Congenital cystic lesions of the oral cavity are an extremely rare occurrence. Their prenatal diagnosis is essential since they can impede respiratory and swallowing functions. We describe a case that was detected prenatally and discuss its management. CASE REPORT: A 21-year-old primigravida patient who was 23 weeks pregnant was referred to our obstetrics and gynecology center after fetal ultrasonography showed a cystic lesion of the oral cavity. She had no family history of any congenital anomalies...

Use of ultrasonography (US) in dentomaxillofacial region became popular in recent years owing to increasing radiation dose concerns and economic limitations. It helps to visualize fine detail of the surface structure of the oral and maxillofacial tissues without ionizing radiation. In diagnostic ultrasound, high frequency sound waves are transmitted into the body by a transducer and echoes from tissue interface are detected and displayed on a screen. Sound waves are emitted via piezoelectric crystals from the ultrasound transducer...

BACKGROUND: Renal cell carcinoma (RCC) - also known as hypernephroma or grawitz tumor - accounts for 3% of the adulthood malignancies. Approximately 30-40% of the patients have metastasis at the time of the diagnosis and most common sites for metastasis are lung, regional lymph nodes, bone and liver. A total of 8-14% of the patients with RCC has head and neck metastasis. However, metastasis to major salivary glands is rarely seen. In this paper, we aimed to report a RCC case with metastasis to parotid and submandibular glands that has the same sonographic and sonoelastographic findings with the primary tumor...

OBJECTIVES: The diagnosis of primary Sjögren's syndrome (pSS) rests on a converging set of clinical and laboratory findings. Salivary-gland ultrasonography (SGUS) was recently shown to assist in the diagnosis and therapeutic monitoring of pSS. Our objective here was to measure salivary-gland elasticity using Acoustic Radiation Force Impulse (ARFI) ultrasonography in patients with pSS and to compare the results to those obtained in healthy controls. METHODS: SGUS with ARFI elastometry was performed in 10 patients with pSS and 15 healthy controls...
