INTRODUCTION: First case of radiation-induced parotid leiomyosarcoma. ANATOMO-CLINICAL OBSERVATION: A 50-year-old woman with a history of cervical irradiation for Hodgkin's lymphoma presented with a right parotid tumefaction. Examination noted a deep adherent pretragal mass with peripheral facial palsy. A total parotidectomy with intra-operative examination and cervical curage was performed. Histopathological analysis concluded to a grade 3 parotid leiomyosarcoma according to the National Federation of Cancer Centers...

INTRODUCTION: The anatomical complexity of the temporal region makes it so treatments with fill-ins are challenging due to high vascular risk. Techniques which provide safer procedures must be encouraged. GOAL: Suggest access to the temple through the inferolateral orbital region as a means for safer temporal fill-ins. METHODS: The fanning technique was plotted out not only via the conventional access (pretragal) but via the proposed one as well...

Objective: To assess the influence of benign mass lesions in the superficial lobe of parotid on the known anatomic landmarks for identifying the facial nerve trunk. Method: Patients with unilateral biopsy-proven benign mass lesions in the superficial parotid were selected for this observational study. During superficial/partial superficial parotidectomy, distance of the facial nerve trunk from each landmark was assessed using spring calliper and correlated with the lesion's volume (measured from the pre-operative imaging)...

OBJECTIVE: To compare outcomes of transcanal endoscopic tympanoplasty reconstructed using pretragal superficial musculoaponeurotic system (SMAS) fascia versus temporalis fascia. STUDY DESIGN: Retrospective patient review and posttreatment questionnaire survey. SETTING: Tertiary referral center. PATIENTS: Sixty adult patients with chronic dry tympanic membrane perforation. INTERVENTIONS: Patients underwent transcanal endoscopic type I tympanoplasty reconstructed using the SMAS fascia between September 2017 and May 2018; outcomes were compared with a matched cohort of patients where the temporalis fascia was used...

Due to the variety in the shape of dysmorphic cartilage, tragus reconstruction is one of the most challenging goals in otoplasty. The authors describe a method to reconstruct a prominent tragus in a simple way suitable for accounting for the size, shape, and location of the remaining ear. We present a case of tragus deformity in an 11-year-old female patient after a previous excision of pretragal skin tags. There was a small remnant of the deeply located dystopic cartilage in a horizontal orientation. The dystopic cartilage was used to reconstruct the tragus using a chondrocutaneous transposition flap...

BACKGROUND: Accessory auricles (AAs) are common congenital anomalies. We present a new classification according to location and shape, and propose a system for coding the classifications. METHODS: This study was conducted by reviewing the records of 502 patients who underwent surgery for AA. AAs were classified into three anatomical types: intraauricular, preauricular, and buccal. Intraauricular AAs were divided into three subtypes: intracrural, intratragal, and intralobal...

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...

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...

The present work report cases of auricular burns after routine otologic surgery possibly induced by the operating microscope. Single-center retrospective study. April 2013 to January 2014, eight children presented with auricular burns after otologic surgery. Median age was 10.1 years. Cheloid scar occurred in six cases. A small scar was present for the other two patients without any other sequelae. No patient had chondritis nor cartilage loss. There was no possibility of physical or electrical trauma in the pretragal or retroauricular cutaneous area during the operations...

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. (Aesthetic Surg J 2001;21:564-568.).

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...
