Objective: Branchial apparatus anomalies of the fourth cleft are the rarest subtype of anomaly and occasionally present with suppurative thyroiditis or thyroid abscess due to their relationship with the thyroid gland. Surgical approaches vary and some surgeons favor cauterization of associated pyriform sinus tracts alone versus complete surgical excision. Currently, the literature is scarce and there is limited data on surgical outcomes and procedural steps. Here we describe a combination surgical technique for fourth branchial anomalies including: (1) surgical excision of the cyst and any external pit, (2) hemithyroidectomy, and (3) direct laryngoscopy with cauterization of pyriform apex tract, if present. Methods: A retrospective review was performed on all patients who underwent surgical excision of fourth branchial apparatus lesions (including fistulae, cysts, and sinus tracts) at an urban pediatric university hospital from 2000 to 2019. Data regarding demographics, medical history, surgical methods, complications, and surgical cure rates were collected. Results: A total of 16 patients (9 female, 7 male) underwent a combination surgical procedure for fourth branchial apparatus lesions. Success rate after primary surgery was 94%. One patient had residual disease requiring re-operation. Two patients had post-operative complications: 1 transient vocal fold paresis and 1 seroma, both managed conservatively. A consensus surgical algorithm was created based on operative steps present in the majority of cases. Conclusion: A combination approach to fourth branchial apparatus lesions—including endoscopic cauterization, external excision, and hemithyroidectomy—is safe and provides a high rate of primary cure. Although less invasive options exist, remnants of the branchial lesion, especially in the thyroid, may remain and cause recurrent issues. Therefore, we advocate for complete surgical excision of this rare developmental anomaly, especially when obvious thyroid involvement exists.

Recurrent neck abscess is a typical feature of branchial anomaly. Open surgical excision has been the primary treatment modality for past decades however several alternative treatment modalities such as endoscopic electrocauterization has recently gained popularity and acceptance universally. This series aims to introduce endoscopic assessment as the first line diagnostic and therapeutic management for branchial fistula. 5 patients underwent examination under general anesthesia via direct laryngoscopy, endoscopic assessment and cauterization in our centre from 2016 to 2019. They were then followed up at our clinic to assess disease progression. Comparison between open neck surgery and endoscopic cauterization of internal sinus tract opening as the primary treatment has reported similar recurrence rate. Proposal of endoscopic assessment as the first line investigation and diagnostic tool with the aim of therapeutic cauterization at the same setting. MRI may be needed in scenarios such as failed endoscopic treatment or when open surgery is required.

Purpose The purpose of this work was to determine the epidemiology and the predictive factors of success of the surgical management of fourth branchial anomalies. Methods This is a multicentric retrospective review from 1998 to 2016 of patients who presented with an endoscopically-confirmed fourth branchial pouch anomaly. Data were analyzed according to sex, age, clinical features, number of recurrences, treatment modalities (endoscopic and/or cervicotomy), post-operative complications and follow-up. Results Fifty-two children have been included. The average age at diagnosis was 4.5 years. Among them, 73.1% were female, 11.4% were neonatal forms; 94.2% of lesions were left-sided; 75% of patients presented a cervical abscess as first symptom, and 7.7% of children presented with dyspnea. Average time between first symptoms and management was 9.5 months. Management was endoscopic in 73.1% of patients (laser in 84.2%, coagulation in 15.8%) with about a third of recurrence after one procedure. Overall success of endoscopic procedures reached 84.2%. A cervical open surgery was performed in 26.9% as first line treatment. Overall success of cervicotomy reached 85.7%. No complications of endoscopic surgery have been identified. There were 35.7% complications of cervicotomy (2 recurrent nerve palsy, 2 keloid scars, 1 pharyngostoma). An association was proved between recurrences and initial abscess (OR = 2.44), and with age between 3 and 5 (OR = 4). Conclusion Endoscopic treatments appear to be effective in first line approach in the management of fourth branchial anomalies, offering an excellent efficiency with rare complications. We identified two risk factors of recurrence: age between 3 and 5 years old and history of cervical abscesses. Level of evidence IV.

Congenital anomalies of the head and neck manifest from errors in its complex embryology developing into mature structures. These abnormalities may herald at birth or become evident later in life, even to the tenth decade. The results of aberrant development may be difficult to diagnose, but knowledge of the relevant embryological pathways is key to identification and successful treatment. This chapter reviews the anomalies of the embryonic neck tissues: the branchial apparatus, skin and adnexal tissues, mesoderm, and skeleton.

The presence of a neck mass in newborn, infant, and children is most frequently benign (90%). In order of frequency, the origin can be congenital, inflammatory, or a benign neoplasm. A small minority of cases (3%) correspond to a malignant neoplasm.

Branchial arch and cleft anomalies are congenital malformation of the first, second, third and fourth branchial arch and most frequently present as cysts, sinuses or fistulae in the auricular, mandibular or cervical areas. Good knowledge of embryological development helps to understand the anatomy and relationships of branchial anomalies with surrounding structures, especially the laryngeal nerves (superior and recurrent) and vascular structures. Diagnostic work up includes a good physical exam, ultrasonographical evaluation as well as MRI for cross-sectional imaging in more complicated cases. Fistulogram and endoscopy can also be helpful, especially in third and fourth branchial cleft anomalies. Surgical excision is usually the treatment of choice, on an elective basis. If the cervical cyst, sinus or fistula are infected, incision and drainage and antibiotic treatment are recommended, followed by elective excision when the inflammation has resolved.

We report a case of the first branchial cleft anomaly, clinically typical but occult in images and pathology. An 8-year-old female who had an induration below her right mandibular angle was referred to our department with a diagnosis of an infectious epidermal cyst. CT and MRI had shown no evidence of fistula or cyst. At the initial operation, a string structure was observed, but pathologically no epithelial structure was observed. However, the infection at the same site repeated and the symptoms became more severe than before. Considering a high probability of the first branchial anomaly, partial parotidectomy was performed as radical surgery. A cord structure attached to subcutaneous tissue at the intertragal notch was found. Although no epithelial component in the pathology was detected, this string structure was clinically considered as the rudimentary form of the first branchial anomaly.

Deletions and pathogenic sequence variants in Myeloid Ecotropic Insertion Site 2 (MEIS2) gene have been reported to cause a recognizable triad of intellectual disability, congenital heart malformations, and palatal defects. To date, 18 individuals with de novo pathogenic sequence variants in MEIS2 have been reported in the literature, most with all three cardinal features. We recently saw a young boy, almost 3 years of age, who was known to have mosaic XYY syndrome (47,XYY [23]/46,XY[7]). He presented with atrial and ventricular septal defects, developmental delay, facial dysmorphism, gastroesophageal reflux, undescended testicle, a buried penis with penoscrotal transposition, primary neutropenia, and a branchial cleft sinus. Whole-exome sequencing identified a previously reported in-frame pathogenic deletion (c.998_1000delGAA; p.R333del; NM_170674.4) in MEIS2. His unaffected father was confirmed to have low-level mosaicism for the same MEIS2 variant. The proband represents the 19th reported individual with a pathogenic sequence variant in MEIS2 and expands the phenotypic spectrum to include primary neutropenia, branchial anomalies, and complex genital anomalies. Furthermore, to our knowledge this is the first reported case of mosaicism for a variant in this gene in an apparently unaffected parent. This finding would have implications for recurrence risk counseling for families.

Purpose: To report an unusual occurrence of HPV infection manifesting as a squamous papilloma within a branchial cleft cyst. Study design/Methods: Case report and review of literature. Results: A 64-year-old male presented with a history of recurrent oropharyngeal papillomas concurrent with a cystic neck lesion. Initial FNA biopsy was suspicious for a cystic nodal metastasis of squamous cell carcinoma. Upon excision of the neck mass, histopathologic analysis revealed a squamous papilloma arising from within a branchial cleft cyst. HPV positivity was confirmed with in-situ hybridization. The patient remains disease free after 75 months of follow-up. Conclusions: HPV infections of the upper respiratory tract are potentially transmissible into the neck via a branchial anomaly. Oncologic considerations are discussed. Keywords: Human papilloma virus, Papilloma, Branchial cleft anomaly, Branchial cleft cyst

Type 2 branchial cleft anomalies are the most common cause of lateral neck swelling. We report two cases of type 2 branchial cleft anomalies. The first case is branchial cleft cyst and the second one is branchial fistula. Both cases were managed surgically. The post operative outcomes were uneventful. Second branchial cleft anomalies are the most common branchial anomalies. Branchial cysts are more common than sinuses and branchial fistulae are extremely rare. There is no gender predilection. The location, clinical symptoms and imaging findings aid in the diagnosis of this condition. Surgical excision is the mainstay of treatment.Keywords: branchial cleft; branchial cyst; branchial fistula.

Branchial cyst is a rare developmental disorder which is diagnosed rarely. Remnants of Branchial are present at birth but may become clinically significant later in life. We report a case of 14-year-old male patient with an asymptomatic branchial cyst over lateral side of neck. These cyst originate from remnants of branchial arches or branchial pouches. The definitive treatment of is complete surgical excision of the cyst. Complete surgical excision prevents recurrence or other complications.

Background Branchial anomalies (BAs) account for 20% of all congenital masses in children. We sought to review the incidence of involvement of individual anomalies, diagnostic methods, surgical treatment, and complications of BAs in children. In addition, we also classified our study and analyzed a congenital lower neck cutaneous fistula near the sternoclavicular joint that was thought to be the skin-side remnant of the fourth BAs. Methods We conducted a retrospective analysis of 105 children who were referred to our hospital from June 2009 to December 2016 for the treatment of BAs. Results In this series, there were 51 males and 54 females. The age at the time of operation varied from 19 days to 13 years, and the mean age was 4.5 years. A total of 33 (31.4%) cases presented with first BAs, 13 (12.4%) presented with second BAs, and 59 (56.2%) presented with third and fourth BAs, including 6 cases of congenital lower neck cutaneous fistula. Fistulectomy under general anesthesia was performed on all of them. For postoperative complications, 2 cases had temporary facial paralysis, 1 case had permanent facial paralysis, 4 cases had temporary recurrent laryngeal nerve injury. Recurrence occurred in 2 patients with first BAs after medium follow-up time of 3.6 years (6 months–8 years). Conclusions BAs are common congenital head and neck lesions in children, and there are four distinct types (first, second, third and fourth anomalies). The incidence of third and fourth BAs in Asia maybe higher when compared with literature reports, second BAs seem rare in this population, but more research is needed to confirm this perspective. Diagnosis is not difficult with a proper knowledge of the anatomy of the BAs. The surgical procedures should be tailored depending on the various types, and complete excision of the fistula is the key to prevent recurrence.

Ninety-four patients with second branchial anomalies were retrospectively analysed at a tertiary care centre from January 2006 to September 2016 to determine the demographical data and management. Branchial sinus and fistula presented earlier as compared to branchial cyst. The mean age at presentation in case of branchial sinuses, fistulae and cysts was 5.07, 5.79 and 7.31 years respectively. There was preponderance in males as compared to females, more so in bilateral cases. Male to female sex ratio was 2.91:1. The branchial fistulae were the most common type of lesions, followed by the branchial sinuses. The branchial anomalies were more on the right side (65.96%) probably due to right handedness of the population. Only eight patients (8.51%) had bilateral anomalies. Four patients had familial association, it was seen in bilateral cases and they presented earlier than unilateral cases. Early and complete surgical excision is the treatment of choice. Preoperative sinogram/fistulogram and intraoperative methylene blue dye injection is not mandatory for excision of a branchial sinus/fistula. Post-operative wound infection was the most common complication (4.25%).

Second branchial anomalies represent the most common type of branchial anomalies. Their anatomical course is well understood based on knowledge of the embryologic branchial apparatus. These anomalies tend to present in children, though slow-growing cysts may first be noted well into adulthood. The most common presenting sign is a slowly growing lateral neck mass. Surgical excision remains the mainstay of therapy.

Background: Branchial cleft cyst is rare congenital anomaly and most common cause of head and neck pathology in children. Second branchial cyst accounts 95 % of the all brnchial anomalies. It mostly manifest in 2nd and 3rd decade of life. Early diagnosis, controlling the infection status and complete excision without nerve injury is mainstay of treatment. Recurrence rates is very low after complete surgical excision. Study Design: Retrospective study. Setting: Department of Otolaryngology, Head and Neck Surgery, Benazir Bhutto Hospital Rawalpindi. Period: 02 year from August 2016 to July 2018. Methods: 04 cases of branchial anomalies. Age, sex, and duration of symptoms were noted from the case records. The side and site of the lesion and the site of opening of sinuses and fistula were noted. The cystic lesions were investigated with ultrasound and CT scan. Surgical excision of cyst and sinus done. Results: The structure of the studied group was as follows: the ratio men/women was of approximately 3/1; the ratio branchial cysts/branchial sinuses/branchial fistulae = 2/2/0. Age ranged from 16 to 27 years. Two patients presented with left neck swelling and one patient presented with right neck swelling and one with right sided discharging sinus. Complete surgical excision was done in all cases and no complication occured. Conclusion: Branchial cysts are commonly misdiagnosed and rarely included in the differential diagnosis. Physician should suspect in any patient with a swelling in the lateral part of the neck.

A bilobed tongue base was identified in an infant with multiple other head, neck and cardiac congenital anomalies. This anatomical variation of the posterior tongue is rare, with only two other cases identified in the literature. We report a case of a 5-month-old boy with a bilobed posterior tongue incidentally identified during workup for cardiac surgery.

Objectives/Hypothesis We present a new method of optimizing the results of surgery for branchial cleft anomalies based on the intraoperative injection of fibrin glue combined with methylene blue dye. Study Design Retrospective single-center cohort study. Methods The method was applied in 17 patients suffering from branchial anomalies. Six (35.29%) had a preauricular lesion; three (17.65%) had lesions derived from the first arch/pouch/groove (type I), four (23.53%) had lesions derived from the first (type II), one (5.88%) had lesions derived from the second, one (5.88%) had lesions derived from the third, and two (11.76%) had lesions derived from the fourth. The median and mean age at surgery were 10 and 10.6 years, respectively. All patients were followed by periodic clinical and ultrasonographic examination. Results The combination of fibrin glue with methylene blue facilitated the correct assessment of the extension of the lesions and their intraoperative manipulation. After a mean follow-up of 47.8 months, all patients were free of disease. Conclusions Intraoperative injection of branchial fistulae and cysts by a mixture of fibrin glue and methylene blue is an effective, easy, and safe tool to track lesions and achieve radical resection. The technique requires a definitive validation on a large cohort with adequate stratification of patients. Level of Evidence 4 Laryngoscope, 2015

First branchial cleft anomalies are an uncommon group of congenital malformations. Anatomically complex in origin, they present with an impressive array of signs and symptoms. There are several classification systems available, rendering them challenging in terms of preoperative assessment and surgical planning. The objective of this report is to describe the presentation, surgical treatment, and outcome of a child presenting with a complex cerumen containing duplication of the external ear canal running medial to the facial nerve. Diagnostic and management pitfalls in the approach to pediatric patients with first branchial anomalies are outlined. A review of the literature is presented.

First branchial cleft anomalies constitute a rare entity with variable clinical presentations and anatomic findings. We describe a 14-month-old girl with a congenital cutaneous fistula running from a cutaneous opening in the left submandibular triangle through the submandibular gland and ending in the pharyngeal cavity. These features suggested type II first branchial cleft fistula with an extremely unusual path. Complete excision resulted in successful treatment without recurrence. Since the first branchial cleft fistula can originate anywhere along the salivary gland and can extend from this area, surgeons should maintain a high index of suspicion for anatomic variants of this rare condition.

Branchial anomalies (BA) are developmental lesions that are believed to be either vestigial remnants resulting from incomplete obliteration of the branchial apparatus or the result of buried epithelial cell rests.

Type II branchial cleft anomalies are the most frequent branchial anomaly (90%). Type I, III and IV branchial cleft anomalies are much rarer. We report the case of a young woman who underwent 12 operations before the correct diagnosis of a type IV branchial arch anomaly was made. Direct laryngoscopy and computed tomography after barium swallow confirmed the sinus tract. Branchial cysts, fistulas, and sinuses are anomalies of the branchial apparatus occurring after failure of a branchial cleft to involute. Branchial anomalies may be diagnosed at any age but present most commonly in infancy and childhood.1 Derivates from the fourth pharyngeal arch are the superior parathyroid glands, various muscles, the thyroid and epiglottic cartilage, and the vagal nerve.2 Fourth branchial anomalies begin in the apex of the piriform fossa, pierce the larynx near the cricothyroid ligament, and then pass between the superior and recurrent laryngeal nerves (Figure ​(Figure1).1). Left‐sided anomalies descend in the tracheoesophageal groove and loops around the aorta, ascending posteriorly to the common carotid before passing over the hypoglossal nerve. On the right side, the fistulas loop around the subclavian artery.3 Open in a separate window Figure 1 Anatomic course of type IV fistulas, SLN superior laryngeal nerve, CN cranial nerve, RLN recurrent laryngeal nerve, JV jugular vein

Observation of a sinus tract during a barium swallow examination is important for the diagnosis of pyriform sinus fistula; however, to our knowledge, no reports have existed regarding the optimal timing of the examination in relation to the onset of symptoms. The purpose of this study was to compare the timing of the examination, patient age, the number of inflammatory episodes that occurred before the examination, and the barium concentration used for examinations with true-positive results versus those with false-negative results for the diagnosis of pyriform sinus fistula.Twenty-three children with pyriform sinus fistula were included. The timing of the examination, patient age, the number of the inflammatory episodes that occurred before examination, and the barium concentration used were compared between examinations with true-positive results and examinations with false-negative results, by use of the Mann-Whitney U test.The examination had true-positive results for 60.9% (14/23) of patients and false-negative results for 39.1% (9/23) of patients. The mean (± SD) interval since the onset of symptoms was significantly shorter for patients with false-negative examination results than for those with true-positive examination results (26.33 ± 21.17 days vs 48.57 ± 17.67 days; p = 0.020). By 6 weeks after the onset of symptoms, more than half of the examinations had false-negative results. No significant difference in patient age (p = 0.238) or number of previous inflammatory episodes (p = 0.431) existed between examinations with true-positive and false-negative results; however, a significant difference was noted in the mean barium concentration used (88.57% ± 31.53% vs 52.86% ± 18.68% weight/volume, respectively; p = 0.014).Barium swallow examinations with false-negative results were significantly more likely when the examination was performed soon after the onset of symptoms. Therefore, early first examinations would not be recommended for the diagnosis of pyriform sinus fistula, especially in terms of radiation exposure. A higher barium concentration may be useful.

Branchial cleft cysts (BCC) are benign lesions caused by anomalous development of the branchial apparatus. This case report describes a 63-year-old woman with a 12 cm×12cm sized cystic mass located anterior to the manubrium sternum and sternum. MRI revealed a cystic lesion with a sinus tracking to the piriform sinus. Postoperative histopathological examination confirmed the diagnosis of branchial cleft cyst. Because of the course of the sinus track, it is believed that this was a fourth branchial cleft cyst. These are the rarest of the branchial anomalies, and extension below the peri-thyroid region is very infrequently described. When this extension occurs, it is always post-sternal into the mediastinum, and the pre-sternal presentation here appears to be unique. A review of the relevant literature was performed to summarize the clinical features of fourth branchial cleft cyst and to identify the best options for diagnosis and treatment.

Objective To review our experience treating hypopharyngeal branchial anomalies utilizing an open transcervical approach that: (1) includes recurrent laryngeal nerve (RLN) monitoring and identification if needed; (2) resection of tract if present; and (3) a superiorly based sternothyroid muscle flap for closure. Methods A retrospective chart review was performed to identify all patients at a tertiary level children's hospital with branchial anomalies from 2005 to 2014. The clinical presentation, evaluation, treatment and outcome were analyzed for those patients with hypopharyngeal branchial anomalies. Results Forty-seven patients who underwent excision of branchial anomalies with a known origin were identified. Thirteen patients had hypopharyngeal branchial anomalies. Six of these patients were treated by the authors of this study and are the focus of this analysis. All six underwent an open transcervical procedure with a sternothyroid muscle flap closure of a piriform sinus opening over a nine year period. Definitive surgery included a microlaryngoscopy and an open transcervical approach to close a fistula between the piriform sinus and neck with recurrent laryngeal nerve monitoring or dissection. A superiorly based sternothyroid muscle flap was used to close the sinus opening. There were no recurrences, recurrent laryngeal nerve injuries or other complications from these procedures. Conclusions This study supports complete surgical extirpation of the fistula tract using an open cervical approach, recurrent laryngeal nerve monitoring or identification, and rotational muscle flap closure to treat patients with hypopharyngeal branchial anomalies.

The objective of the present study was to review the distribution and incidence of branchial anomalies in an Asian paediatric population and highlight the challenges involved in the diagnosis of branchial anomalies.This was a retrospective chart review of all paediatric patients who underwent surgery for branchial anomalies in a tertiary paediatric hospital from August 2007 to November 2012. The clinical notes were correlated with preoperative radiological investigations, intraoperative findings and histology results. Branchial anomalies were classified based on the results of the review.A total of 28 children underwent surgery for 30 branchial anomalies during the review period. Two children had bilateral branchial anomalies requiring excision. Of the 30 branchial anomalies, 7 (23.3%) were first branchial anomalies, 5 (16.7%) were second branchial anomalies, 3 (10.0%) were third branchial anomalies, and 4 (13.3%) were fourth branchial anomalies (one of the four patients with fourth branchial anomalies had bilateral branchial anomalies). In addition, seven children had 8 (26.7%) branchial anomalies that were thought to originate from the pyriform sinus; however, we were unable to determine if these anomalies were from the third or fourth branchial arches. There was inadequate information on the remaining 3 (10.0%) branchial anomalies for classification.The incidence of second branchial anomalies appears to be lower in our Asian paediatric population, while that of third and fourth branchial anomalies was higher. Knowledge of embryology and the related anatomy of the branchial apparatus is crucial in the identification of the type of branchial anomaly.

Pyriform sinus malformations represent rare third and fourth branchial anomalies. Fistulae at the latter site were initially described and make up less than 1 % of all brachial anomalies. They may be discovered incidentally, or may present as a neck mass with recurrent infection, dysphagia, or airway compromise, and can be an unusual cause of dysphonia in infant and children. Here, we present a case of third branchial cyst located in pharyngeal wall of the left pyriform sinus which presented with dysphonia since birth in a 6-year-old girl. Transoral CO2 laser excision was carried out successfully with no communicating tract. The patient's dysphonia showed progressive regression at 1-year follow-up. Third branchial cyst in the left pyriform sinus (Bailey's type IV) is an unusual cause of dysphonia in pediatric. Our present case report is the first brachial cyst to be reported in the pyriform fossa and the second branchial anomalies to be excised transorally with CO2 laser.

Pyriform sinus fistula is a rare congenital anomaly affecting the third or fourth branchial arches. It is often overlooked, and poses a diagnostic and management challenge. We report the case of an infant with recurrent neck infections despite appropriate treatment that was finally diagnosed as pyriform sinus fistula.

Cystic masses of the neck may represent a wide variety of pathological conditions. Among these, branchial anomalies are the commonest paediatric congenital lesions of the head and neck. This article intends to review this condition under the same headings, as well as facilitate their diagnosis with the help of appropriate radiological findings of patients diagnosed with these anomalies. In order to make an accurate diagnosis, it is imperative to have an idea about the possible differentials, and the normal embryological development of the branchial arches, as well as their anomalies, in the form of sinuses, fistulae, and cysts, with their features and subtypes. The medical history of the patient and clinical manifestations helps in suspecting branchial cleft cysts; confirmatory imaging modalities include computed tomography, magnetic resonance imaging, ultrasonography, and fine-needle aspiration. The mainstay of management is usually by surgical excision. The location, clinical picture, and radiological correlation, along with a strong degree of suspicion for the condition, facilitates the diagnosis of this relatively common embryological anomaly.

Neck lesions in children can be congenital or acquired in origin. Accurate diagnosis aids in the management of these lesions. Thyroglossal cyst and sinuses are the most common congenital neck lesion followed by branchial anomalies.

Introduction: Pyriform sinus fistula is a rare cervical branchial anomaly derived from the third and fourth branchial arch. Pyriform sinus fistula should be considered in children presenting enlarged neck mass, fistula, abscess, thyroid infection and/or dysphonia. Objective: We here report 4 cases treated in Hospital Clinico Universidad de Chile and review of the current literature on pyriform sinus fistula. Discussion: When clinical presentation is compatible with pyriform sinus fistula, endoscopic and imaging techniques are required. Surgical outcomes are better, although endoscopic therapies and combination of both surgery and endoscopy have also reported good outcomes. Conclusion: Diagnosis is made based on signs and symptoms and a high index of clinical suspicion. Open surgery is gold standard, however in pediatric population endoscopic resolution should be considered to reduce the high morbidity of traditional surgery.

Backgrounds Second branchial cleft anomalies predispose to recurrent infections, and surgical resection is recommended as the treatment of choice. There is no clear consensus regarding the timing or surgical technique in the operative treatment of these anomalies. Our aim was to compare the effect of age and operative techniques to patient characteristics and treatment outcome. Methods A retrospective study of pediatric patients treated for second branchial sinuses or fistulae during 1998–2012 at two departments in our academic tertiary care referral center. Comparison of patient characteristics, preoperative investigations, surgical techniques and postoperative sequelae. Results Our data is based on 68 patients, the largest series in the literature. One-fourth (24%) of patients had any infectious symptoms prior to operative treatment. Patient demographics, preoperative investigations, use of methylene blue, or tonsillectomy had no effect on the surgical outcome. There were no re-operations due to residual disease. Three complications were observed postoperatively. Conclusions Our patient series of second branchial cleft sinuses/fistulae is the largest so far and enables analyses of patient characteristics and surgical outcomes more reliably than previously. Preoperative symptoms are infrequent and mild. There was no difference in clinical outcome between the observed departments. Performing ipsilateral tonsillectomy gave no outcome benefits. The operation may be delayed to an age of approximately three years when anesthesiological risks are and possible harms are best avoided. Considering postoperative pain and risk of postoperative hemorrhage a routine tonsillectomy should not be included to the operative treatment of second branchial cleft fistulae.

Summary Introduction A retrospective clinical trial was conducted to evaluate the clinical features and treatment outcomes and to determine the incidence of complications in children with congenital neck lesions (CNLs) treated at our institution with a special emphasis on thyroglossal duct remnant (TGDR), branchial cleft anomaly (BCA), and dermoid cyst (DC). Materials and methods This series had 72 patients with CNL. The diagnosis of CNL was made by physical examination, ultrasound (US) in most, and for a potential extension of the mass computed tomography (CT) or magnetic resonance imaging (MRI) in a few patients and confirmed by histopathological examination in all of the children. Results Of the patients in this series, 39 (54.2%) children had thyroglossal duct remnant (TGDR). The most common surgical procedure ( n = 36) in these children was Sistrunk's procedure. Four children (10.3%) with TGDR had associated anomalies including Turner syndrome and Morgagni hernia. During the study period, 25 (34.7%) children with branchial cleft anomaly (BCA) were treated and most of these were second branchial anomalies. There were eight children (11.1%) with dermoid cyst (DC). Conclusion TGDR is the most common CNL and is presented clinically rather late with regard to BCA and DC in this series. Surgical resection is optimal choice of therapy in CNLs not only for aesthetic reasons but also for the recurrent infections and the potential danger of malignancy. Definitive surgery may be associated with high morbidity, especially recurrence. Associated anomalies may be observed, especially in children with TGDR. Although the Sistrunk's procedure is a safe and successful technique, life-threatening complications should also be kept in mind during the management of these lesions and early and adequate surgical treatment is suggested.

First branchial cleft anomalies are rare congenital malformations of the head and neck region. These anomalies account for less than 1% of all branchial anomalies. They are frequently misdiagnosed and hence mismanaged. The lesions are variable in presentation and course, making radiographic imaging techniques such as computed tomographic fistulography and magnetic resonance imaging the best first step in managing such cases. We present a 17-year-old Caucasian female who had a first branchial cleft fistula communicating between the right external auditory canal and the angle of the mandible. Surgical exploration revealed a completely subcutaneous tract not involving the parotid gland parenchyma, which makes this case even more significant.
