Craniofacial Microsomia (CFM) also known as Oculo-auriculo-vertebral Spectrum (OAVS) or Goldenhar Syndrome, presents wide phenotypic and etiological heterogeneity. It affects mainly the structures originated from the first and second pharyngeal arches. In addition, other major anomalies may also be found, including congenital heart diseases. In this study, we report a patient with distal deletion in the 22q11.2 region and a phenotype which resembles CFM. The proband is a girl, who presented bilateral preauricular tags, left auditory canal stenosis, - malar hypoplasia, cleft lip and palate, mild asymmetry of soft tissue in face, congenital heart disease, intestinal atresia, annular pancreas and hydronephrosis...

OBJECTIVES: Although the presence of a preauricular sulcus is often cited as an indicator of female sex, very little research has been conducted to substantiate this claim. This article examines both the relationship between the incidence and morphology of the preauricular sulcus and sex. MATERIALS AND METHODS: A total of 500 left ossa coxae from the Hamann-Todd Human Osteological Collection belonging to 261 males and 239 females were examined to investigate the relationship between the preauricular sulcus and sex...

BACKGROUND: Arteriovenous fistula (AVF) is defined as an abnormal communication between the high flow arterial system and the low flow venous network, which directly connects the arterial feeding vessels and the near draining veins without normal intervening capillary bed. Arteriovenous fistula incurs in preauricular region is exceeding rare. Most of these fistulae occur as a result of an iatrogenic injury, the volume is small, feeding and draining vessels of feeding and draining are simple, and can be cured easily...

Tenosynovial giant cell tumor of diffuse type (TGCT-d) or pigmented villonodular synovitis (PVNS) is a locally aggressive lesion that mostly affects the joints of long bones. Chondroid tenosynovial giant cell tumor (CTGCT) or PVNS with chondroid metaplasia is a rare distinct subset of synovial tumors that has a predilection for the TMJ. We report a rare case of CTGCT in the TMJ, initially misdiagnosed as temporomandibular disorder (TMD). A 51-year-old woman was referred to the surgeon with the chief complaint of TMJ pain for 5 years and a past history of an unsuccessful TMD treatment...

Wolf-Hirschhorn Syndrome (WHS) is a rare genetic disease caused by deletion in the short arm of chromosome 4. It is characterized by typical fascial features and a varying degree of intellectual disabilities and multiple systemic involvement. Epidemiological studies confirmed the association of acute pancreatitis with the development of diabetes. However, this association has not been reported in WHS. We report an 18-year-old girl with WHS who presented acutely with nonketotic Hyperglycemic Hyperosmolar Status (HHS) in association with severe acute pancreatitis...

Lipomas of the parotid gland are benign tumors developing from the fatty tissue in the gland. They are rare, accounting for 0.6-4.4% of all benign tumors. Those located in the deep lobe of the gland are uncommon. Clinically, they are very difficult to diagnose. CT scan and especially MRI can support the diagnosis. Surgery is the treatment of choice but its modalities remain controversial. We report the case of a 52-year old female patient, with no particular past medical history, presenting with asymptomatic left preauricular mass evolving over 1 year and gradually increasing in volume...

Background: Osteochondroma is a benign tumor that tends to develop in mandibular condyle and coronoid process in the craniofacial region. If tumor mass has grown from condyle into the infratemporal space with zygomatic arch obstructing the access, there are risks associated with surgical exposure and local resection of these masses. Case presentation: This study reports on a case of osteochondroma on mandibular condylar head where we treated with surgical excision via preauricular approach with 3D analysis...

Branchio-oto-renal syndrome (BOR) is a rare autosomal dominant disorder. The features include branchial cysts, hearing loss, ear malformation, preauricular pits, retrognathia, congenital heart disease, and renal abnormalities. However, anesthetic management of these patients has seldom been reported. We report a case in which general anesthesia was performed for dental treatment in a patient with BOR. Airway management, renal function, and hemodynamic changes can be of critical concern during anesthetic management...

The somatotopy of the trigeminocervical complex of the rat was defined as a basis for describing circuitry for reflex behaviors directed through the facial motor nucleus. Thus, transganglionic transport of horseradish peroxidase conjugates applied to individual nerves/peripheral receptive fields showed that nerves innervating oropharyngeal structures projected most rostrally, followed by nerves innervating snout, periocular, and then periauricular receptive fields most caudally. Nerves innervating mucosae or glabrous receptive fields terminated densely in laminae I, II, and V of the trigeminocervical complex, while those innervating hairy skin terminated in laminae I-V...

A 60-year-old woman presented with a painless swelling in the right preauricular region. Physical examination revealed a soft, nontender, oval-shaped lump in this location. Computed tomography indicated an anterolateral cystic lesion that was attached to the condyle of the mandible and to the accessory parotid gland. Differential diagnoses included ganglion cyst, synovial cyst of the temporomandibular joint, and accessory parotid gland cyst. Surgical removal of the cyst was performed with the patient under general anesthesia...

BACKGROUND: Mechanical properties of tissue-engineered cartilage and a variety of endogenous cartilage were measured. The main goal was to evaluate if the tissue-engineered cartilage have similar mechanical characteristics to be replaced with rib cartilage in microtia reconstruction. Such study lays the foundation for future human clinical trials for microtia reconstruction. METHOD: Atomic force microscopy and compression testing were used to measure the viscoelasticity of tissue-engineered cartilage (stem cell seeded on Poly lactic co-glycolytic acid nanofibers and Pellet) and endogenous cartilage: conchal bowl, microtic ears, preauricular remnants, and rib...

Tuberculosis (TB) is a very common health problem in developing nations such as India. It can present as its primary form or as secondary forms (extrapulmonary TB). Maxillofacial manifestations of TB compose nearly 10% of all extrapulmonary manifestations of the disease. Extrapulmonary TB involving the maxillofacial region is very rare and can present in any tissues in this region. These infections generally involve the head and neck through hematogenous or lymphatic routes. Very few cases of primary TB of the temporomandibular joint (TMJ) have been reported in the literature...

The ectopic accessory parotid system (EAPS) connotes an extra parotid tissue with its ductal outlet that is morphologically distinct from the main parotid gland and its drainage system. Clinically presenting as a saliva-draining cheek fistula near the oral commissure, this rare congenital anomaly is almost always associated with ipsilateral preauricular appendages and occasional mandibular hypoplasia, and is considered a variant of the oculo-auriculo-vertebral spectrum. This report discusses the embryology, clinical details, and management aspects in a new patient, highlighting the role of magnetic resonance imaging in, for the first time, tracking the ectopic salivary system, and establishing its independent existence...

Erythromelanosis follicularis faciei et colli (EFFC) is a distinct, rare, and underdiagnosed condition of unknown etiology that is characterized by well-demarcated erythema, hyperpigmentation, and follicular papules. The pigmentation is usually on both maxillary, preauricular regions, and the cheeks. We report a case of a 12-year-old boy with EFFC that was associated with reticulated pigmentation of the extremities.

REVIEW
Maurício de Maio, Koen DeBoulle, André Braz, Rod J Rohrich
This second article of a three-part series addresses techniques and recommendations for aesthetic treatment of the midface. Injectable fillers are important for rejuvenation of the midface by replacing lost volume and providing structural support; neuromodulators play a smaller role in this facial region. Fillers are used for volumization and contouring of the midface regions, including the upper cheek and lid-cheek junction and the submalar and preauricular areas. Also, treatment of the frontonasal angle, the dorsum, the nasolabial angle, and the columella may be used to shape and contour the nose...
