OBJECTIVES: To present and characterize CT and MR imaging findings of metastases to the parotid nodes. METHODS: CT (n = 10) and MR (n = 11) images from 14 patients with metastases to the parotid nodes were reviewed. The primary tumour sites were the ocular adnexa in five patients, facial skin in four patients, upper aerodigestive tract in four patients and thyroid gland in one patient. CT and MR images were evaluated with emphasis on the size and number of parotid tumours, their location in the parotid gland, the presence of associated clinically pathological cervical nodes or previous history of cervical node metastasis, margin characteristics and the presence of central necrosis...

BACKGROUND: Non-thrombotic pulmonary embolism has recently been reported as a remote complication of filler injections to correct hollowing in the temporal region. The middle temporal vein (MTV) has been identified as being highly susceptible to accidental injection. METHODS: The anatomy and tributaries of the MTV were investigated in six soft embalmed cadavers. The MTV was cannulated and injected in both anterograde and retrograde directions in ten additional cadavers using saline and black filler, respectively...

COMPARATIVE STUDY
Chul Park
BACKGROUND: Patients with solitary-type congenital tragal malformations accompanied by dystopic cartilage growth (accessory tragus) show not only a disfigured or absent tragus but also unnecessary tragal or pretragal lumps. Furthermore, an absent tragus causes a wholly exposed external auditory canal. MATERIALS: Sixty-five ears (54 patients) showing congenital tragal malformations accompanied by dystopic cartilage growth were reconstructed from March of 1991 to February of 2014...

BACKGROUND: The aim of this study was to create a new flap based method for zygomatic cheek defect reconstruction using the pretragal perforator from the superficial temporal artery. METHODS: Ten fresh cadavers were dissected after vascular injection to study pretragal perforator distribution, length, and diameter. Twelve clinical cases of zygomatic cheek defects were reconstructed using pretragal perforator flaps. According to the location of the perforator that was preoperatively probed using an ultrasound Doppler blood flow detector and the zygomatic cheek defect condition, size, and distance from the distal border to the tragus and the flabby surrounding skin, we designed a spindle-shaped longitudinal flap in the preauricular region based on the pretragus...

INTRODUCTION: Depending upon the type of communication between the internal carotid artery and the cavernous sinus, two types of carotid-cavernous fistulae can be distinguished: direct carotid-cavernous fistula (DCCF), for which diagnosis is usually easy because of the obvious signs of orbital congestion, and indirect carotid-cavernous fistula (ICCF) or dural fistula, with few symptoms, associated with a delay in diagnosis which can alter prognosis for function and even life. PURPOSE: The purpose of this study is to determine characteristic signs of both types of CCF and to study their correlation with the anatomical type of vessels involved on the angiogram...

Six lop rabbits were presented with clinical signs of otitis media or externa. The presence of disease was confirmed by computerized tomography examination, with two rabbits suffering from bilateral disease. The rabbits were anaesthetized and underwent surgery of the affected bulla. Rabbits with bilateral disease had a minimum of 2 weeks between procedures. A single vertical incision was made over the base of the vertical canal, which was bluntly dissected free from surrounding tissue. The ventral portion of the vertical canal was removed and a lateral bulla osteotomy was performed...

Goldenhar syndrome is well known for its classical triad of epibulbar dermoids or lipodermoids, auricular appendages and pretragal fistulas. Here we report a case of Goldenhar syndrome with an unusual association of a fibroepithelial polyp attached to a limbal dermoid. A case of Goldenhar syndrome in a 5-month-old male infant presented with the features of a fibroepithelial polyp attached to a limbal dermoid, right-sided polydactylia with hypoplastic thumb, and accessory preauricular appendages on the left side...

BACKGROUND: Arteriovenous malformation (AVM) in the extracranial region is uncommon. The most common sites are cheek, ear, nose, and forehead in order of frequency in the extracranial region. Although the external ear is the second most common site for the extracranial AVM, AVM in the pretragal region has not been reported until now. METHODS AND RESULTS: We reported a case of AVM in the pretragal region, which was successfully removed by complete excision after preoperative selective embolization in a 32-year-old man...

Although an endotragal incision is used in rhytidectomy to avoid a visible pretragal scar, patients may not understand that the superior and inferior portions of the preauricular scar cannot be hidden inside the ear. The endotragal incision is also more likely to distort normal external ear anatomy. The author explains his preference for the pretragal incision and presents his face lift technique.

Facial paralysis associated with benign diseases of the parotid gland is very rare. It has been reported in approximately 16 cases of acute suppurative parotitis or parotid abscess. We presented a 45-year-old woman who developed facial paralysis secondary to an occult parotid abscess. Initially, there was no facial paralysis and the signs and symptoms were suggestive of acute parotitis, for which medical treatment was initiated. Three days later, left-sided facial palsy of HB (House-Brackmann) grade 5 developed...

In most of its anatomical constituents, e.g. in the Helix, etc., the external human ear is homologous to that of all Primates and Scandentia (tree shrews). Thus, its genetic basis is largely older than 60 Mio yrs. Based upon the observation of lifelong growth of the ear (e.g. Montacer-Kuhssary 1959), we aimed to elucidate the growth of the human ear in a more detailed way throughout life and in both sexes. On standardized photographical material collected randomly in Berlin (Germany), we measured N = 1448 ears from neonate children to volunteers of 92 yrs in age...

In this paper introduces a rare case of chondrocalcinosis of the temporomandibular joint secondary to hyperparathyroidism, diagnosed in a 64-year-old man. The patient complained of symptoms characterized by the presence of a swelling in the left pretragic preauricular region, accompanied by a limitation of the mandibular movements. Radiographic examinations suggested a diagnosis of synovial chondromatosis. Subsequently definitive histological analysis removed mass stated for a chondrocalcinosis of the left temporomandibular joint...

BACKGROUND: The delicate shape of the tragus and the pretragal depression are fine landmarks on the face that are usually lost during conventional rhytidectomy. A relatively simple technique to preserve the natural pretragal depression after face lift has been implemented in the authors' practice. It provides an almost invisible incisional scar and avoids tragal distortion. METHODS: Incision starts around the sideburn in a curvilinear fashion toward the helix and continues vertically down into the tragal margin and around the earlobe retroauricularly...

Goldenhar syndrome is well known for its classical triad of epibulbar dermoids or lipodermoids, auricular appendages and pretragal fistulas. The syndrome was later included under the broader classification of oculoauriculovertebral spectrum to cover a wide range of associated anomalies. Here, a case is presented of Goldenhar syndrome in a child from Papua New Guinea. The patient had large epibulbar lipodermoids requiring surgical debulking primarily for mechanical lagophthalmos and secondarily for cosmesis...

Goldenhar syndrome (GS) is a congenital disorder believed to be caused by the defective development of the first and second brachial arches and the first brachial clefts during the fourth through eighth weeks of embryologic development. It is characterized by epibulbar dermoids and/or lipodermoids, preauricular tags, pretragal fistulas, hemifacial microsomia, and vertebral anomalies. Other ocular and nonocular symptoms have also been described. To our knowledge there are only three previous reports of abnormal caruncles in GS...
