Purpose: Branchial cleft anomalies (BCAs) are developmental malformations of the head and neck region. Their histogenesis has been the subject of controversy and is not fully understood. This study aimed to test all present developmental theories ("branchial apparatus," "precervical sinus," "thymopharyngeal," and "inclusion" theories) on a sample of 48 BCAs from a single institution.

Neonates often have congenital lumps or sinuses. It is expected that pediatricians will distinguish those with important physiologic implications from those without. Accurate understanding of these lesions is important for the practitioner to avoid unnecessary tests and anxiety and to ensure that seemingly benign lesions with important implications are addressed in a timely manner.

A dermal sinus/fistula is a common condition; the relevant department should be consulted for appropriate treatment. It is important for radiologists to have adequate knowledge of these conditions to provide the correct diagnosis and recommend subsequent management. This review describes the following lesions: preauricular sinus, midline sinus of the upper lip, nasal dermoid sinus cyst, cheek fistula, first branchial cleft anomaly/sublingual branchial cleft anomaly, thyroglossal duct cyst/fistula, lateral cervical sinus/fistula, congenital dermal sinus/fistula of the anterior chest region, congenital skin sinus/fistula with a sternal cleft, and congenital prepubic sinus.

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

Objective: Although most preauricular sinuses are located near the anterior limb of the ascending helix, some are located in unusual areas around the auricle, as shown previously in limited reports. This study analyzed the clinical manifestations of congenital periauricular fistulas with unusual fistula locations and the possible relationship with the classical preauricular sinus.

Methods: We reviewed the medical records of patients who underwent congenital periauricular sinus excision by three surgeons and followed them for more than 6 months. Read More

The association of branchial arch anomalies (branchial cysts, branchial fistulas), hearing loss and renal anomalies constitutes the branchio-oto-renal (BOR) syndrome also known as Melnick Fraser syndrome. We present a case of this rare disorder in a girl child who presented with profound deafness, preauricular pits, branchial sinuses and renal hypoplasia. Read More

Steatocystoma multiplex is characterized by the development of numerous steatocystomas. The condition has occasionally been related to congenital bilateral preauricular sinuses. Herein, we present the third case of such an association, a 34-year-old male who was born with bilateral preauricular sinuses that were surgically repaired. Read More

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.

We describe what we believe is only the third reported case of coexisting first and bilateral second branchial fistulas associated with nonfamilial branchio-otic syndrome. 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

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

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

Branchiootoic syndrome is part of the spectrum of brachiootorenal disorders. Brachiootorenal disorder is a rare autosomal dominant condition, characterized by malformations of the outer, middle, and inner ear, which are associated with branchial and renal anomalies. We describe a case of bilateral branchiootoic syndrome and discuss the anatomy of second branchial cleft fistulae and the surgical management of this uncommon condition. Read More

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
