    Head and Neck Institute, Department of Otolaryngology - Head and Neck Surgery, 9500 Euclid Avenue, Cleveland Clinic, Cleveland, OH, USA. Electronic address:
    Introduction: Preauricular lesions, including tags, pits, sinuses, and cysts are commonly seen. Some studies have shown increased incidence of hearing loss in these patients but other studies have failed to corroborate this finding. The purpose of this study is to evaluate the incidence of hearing loss in patients with isolated preauricular lesions. Read More

    Reconstruction techniques for tissue defects formed after preauricular sinus excision.
    Arch Plast Surg 2014 Jan 13;41(1):45-9. Epub 2014 Jan 13.
    Department of Plastic and Reconstructive Surgery, Eulji University Hospital, Eulji University School of Medicine, Daejeon, Korea.
    Background: Preauricular sinuses are congenital abnormalities caused by a failure of fusion of the primitive tubercles from which the pinna is formed. When persistent or recurring inflammation occurs, surgical excision of the infected tissue should be considered. Preauricular defects inevitably occur as a result of excisions and are often difficult to resolve with a simple suture; a more effective reconstruction technique is required for treating these defects.

The patient was a 6-year-old girl who presented with bilaterally draining anterior neck puncta, a preauricular sinus, and moderately severe bilateral hearing loss. She had no family history of branchial anomalies. Read More

    A simple and reproducible surgical technique for the management of preauricular sinuses.
    Otolaryngol Head Neck Surg 2013 Sep 15;149(3):399-401. Epub 2013 Jul 15.
    Department of Plastic and Reconstructive Surgery, Uijeongbu St Mary's Hospital, The Catholic University of Korea, Uijeongbu, Korea.
    Preauricular sinus is a relatively common congenital anomaly that mainly exists on the anterior aspect of the anterior limb of the ascending helix. Although many surgical techniques have been developed, extirpation of the sinus is not easy because of the ramifications of the sinus, remnants of the sinus wall, and infection with or without formation of abscesses, which can all lead to disease recurrence. In our institution, we have surgically treated a total of 141 cases of congenital preauricular sinuses. Read More

    Department of Otorhinolaryngology, Yonsei University College of Medicine, Seoul, Korea.
    Preauricular sinuses are common congenital malformations that usually occur at the anterior margin of the ascending limb of the helix. There are rare cases in which the location of the preauricular sinus is posterior to the tragus, and the direction of the sinus tract is toward the posterior. This variant type of preauricular sinus is called, 'postauricular sinus'. Read More

    HPPD: A newly recognized autosomal dominant disorder involving hypertelorism, preauricular sinus, punctal pits, and deafness mapping to chromosome 14q31.
    Am J Med Genet A 2011 May 7;155A(5):976-85. Epub 2011 Apr 7.
    Department of Genetics, LSU Health Sciences Center, New Orleans, Louisiana, USA.
    We report on a novel autosomal dominant disorder with variable phenotypic expression in a three-generation family; the major features include hypertelorism, preauricular sinus, deafness, and punctal pits with lacrimal-duct obstruction. We ruled out the involvement of EYA1, SIX1, and SIX5 as candidate genes by direct sequencing of their exons and by SNP-based linkage analysis. Subsequent SNP-based whole-genome genotyping and parametric multipoint linkage analysis gave lod scores >1 at 14q31 (LOD = 3. Read More

    Homo 2009 11;60(5):461-72. Epub 2009 Sep 11.
    Department of Anthropology, Saugor University, Saugor, M.P., India.
    Somatoscopy of the external ear provides a general idea of the shape of an ear, form of the helix, presence (or absence) of Darwin's tubercle and of the attachment of an ear lobe to a cheek, etc. It is of great importance not only to physical anthropologists but also to plastic surgeons, physicians and forensic scientists. There is no detailed somatoscopic study of the ear morphology concerning the entire Indian subcontinent. Read More

    Department of Otolaryngology, Hospital Universitario Central de Asturias, Instituto Universitario de Oncología del Principado de Asturias, Oviedo, Spain.
    An extremely rare case that has not been reported before is described in which metastasis of a follicular carcinoma of the thyroid is resected from the infratemporal fossa. The patient had not been diagnosed of this thyroid pathology. She underwent a left subtemporal preauricular approach, but after this, she had another subtemporal preauricular approach with total thyroidectomy, a facial translocation by degloving, and an endoscopic surgery, because of a local recurrence, and a sella turcica and sphenoidal sinus metastasis.

    The variant type of preauricular sinus: postauricular sinus.
    Laryngoscope 2007 Oct;117(10):1798-802
    Department of Otolaryngology, Ajou University School of Medicine, Suwon, South Korea.
    Objective: Preauricular sinuses (PAS) are common congenital malformations that usually occur at the anterior margin of the ascending limb of the helix, but the positions of PAS and directions on the fistular tracts are rarely posterior to the external auditory canal (EAC), which presents as a postauricular swelling. We named these cases as the variant type of PAS ('postauricular sinuses'), and compared their clinical manifestations with those of the classical type.

    Syndromic ear anomalies and renal ultrasounds.
    Pediatrics 2001 Aug;108(2):E32
    University of California-Los Angeles, School of Medicine, USA.
    Objective: Although many pediatricians pursue renal ultrasonography when patients are noted to have external ear malformations, there is much confusion over which specific ear malformations do and do not require imaging. The objective of this study was to delineate characteristics of a child with external ear malformations that suggest a greater risk of renal anomalies. We highlight several multiple congenital anomaly (MCA) syndromes that should be considered in a patient who has both ear and renal anomalies. Read More

    Department of Pedodontics, A.B. Shetty Dental College, Mangalore, India.
    Branchio-oto-renal syndrome, first defined in 1976, is an autosomal dominant disorder characterized by anomalies of the external, middle, and inner ear in association with preauricular sinuses, branchial cleft anomalies, and varying degrees of renal dysplasia, including aplasia. Less frequently expressed phenotypic abnormalities include lacrimal duct aplasia and stigmata of renal dysgenesis known as Potter facies. Although the precise incidence of the disorder is unknown, it may be more common than is generally appreciated, and it appears to be distinct from other autosomal dominant otobranchial syndromes.

    Identification of three novel mutations in human EYA1 protein associated with branchio-oto-renal syndrome.
    Hum Mutat 1998 ;11(6):443-9
    Department of Genetics, Center for Hereditary and Communication Disorders, Boys Town National Research Hospital, Omaha, Nebraska 68131, USA.
    The Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by branchial clefts, preauricular sinuses, hearing loss, and renal anomalies. Recent studies have shown that mutations in EYA1 are associated with BOR. However, the underlying molecular mechanisms by which mutations in the EYA1 gene cause BOR syndrome are unknown. Read More
