Objectives: A pyriform sinus fistula (PSF) is a rare congenital anomaly due to failed obliteration of the third or fourth pharyngeal pouch. Diagnosis and management of PSF remains controversial. We present a case of PSF and discuss its diagnosis and management. Methods: Case report and literature review. Results: A 26-year-old female with a chronic left lateral neck abscess was diagnosed with a left PSF. She underwent surgery through a combined approach to close the openings of the PSF, internally and externally. We first placed a blunted ET tube into the internal opening of the PSF. We then performed an external transcervical approach to close the PSF at the cricothyroid membrane. Briefly, after a neck debridement and washout of the chronic neck infection, we identified the recurrent laryngeal nerve (RLN) in Lore's triangle. We performed left hemithyroidectomy to facilitate the dissection and protection of the RLN to its entrance into the larynx. A flexible laryngoscope was then inserted into the left piriform sinus through the ET tube to guide external dissection by transillumination. The scar tissue attached to the superior pole of the left thyroid lobe was then ligated and divided along the cricothyroid membrane. Lastly, we cauterized the internal opening of the PSF. The patient has remained recurrence-free for 1.5 years with normal vocal cord mobility. Histopathology revealed presence of a squamous-lined tract adjacent to the thyroid tissue. Conclusions: Surgical treatment for patients with PSF should be aimed at closing the internal and external openings of the PSF, debriding chronic neck infection, and protecting the laryngeal nerves, instead of removing the entire tract. A concurrent hemithyroidectomy facilitates the identification and protection of the RLN, as well as excision of the tract. Differentiation between third and fourth branchial cleft fistulae may not be clinically necessary, as it is unlikely to alter the therapeutic plan. [ABSTRACT FROM AUTHOR]

Branchiogenic fistulas are congenital alterations that affect the cervical compartments. Those of the fourth branchial cleft are rarest and can begin late with very serious complications. The suppurative thyroiditis can be a complication of these alterations. We describe a case of 3-year-old girl with high fever, left cervical swelling and increased inflammation indices. The neck ultrasound showed an abscess of the left thyroid lobe and a fluid mass with aerial content in laterocervical region. On MRI, the fluid mass extended from the left piriform sinus to the mediastinum. Fluoroscopy also highlighted a fistolose trait that extended from the left side wall of the esophagus, anteriorly towards the trachea. Treatment of these pathologies must be early and a late diagnosis can put patients' lives at risk.

Objective To explore the diagnosis and treatment of fourth branchial cleft deformity. Methods The clinical data of a patient with bilateral fourth branchial cleft deformity in the neck were summarized, and the literature was reviewed. Results The patient was a 17-year-old male who had a painless lump in his neck for 10 years. During specialized examination, a lump approximately 4.0 cm × 3.0 cm in size could be palpated subcutaneously on the right side of the neck, with clear boundaries, a regular shape, a soft texture, and a wave-like sensation without obvious tenderness. A fistula with a size of approximately 0.5 cm × 0.5 cm could be observed on the left side of the neck, and yellow clear liquid could be seen flowing out of the fistula. The surrounding skin was locally red and swollen, and the surface temperature of the skin was elevated. Computed tomography examination demonstrated a circular cystic low-density shadow approximately 4.4 cm × 3.4 cm in size in the right supraclavicular and anterior cervical regions. A flocculent isodense image could be observed in the middle; moreover, nodular calcification could be observed at the edge, and the surrounding fat spaces were blurred. The enhanced scan showed mild enhancement of the cyst wall but no obvious enhancement of the contents. On the left side, a circular nodular shadow with a diameter of approximately 1.4 cm could be seen, with enhanced scanning and circular enhancement. The surrounding skin was thickened, and the subcutaneous fat gap was blurred. Multiple small lymph nodes could be observed on both sides of the neck, with the larger nodes having a short diameter of approximately 0.8 cm. The size and morphology of the thyroid gland were not significantly abnormal, and there was no obvious abnormal density shadow inside of the gland. Upon admission, the diagnosis was a fourth gill fissure cyst in the right neck and a fourth gill fissure fistula in the left neck. Under general anesthesia and intravenous anesthesia, right branchial cleft cyst resection and left branchial cleft fistula resection were performed. Postoperative pathological examination demonstrated a left branchial cleft fistula and a right branchial cleft cyst. The wound healed by first intention, and there was no recurrence after 6 months of follow-up. According to the literature, fourth branchial cleft deformity is a congenital developmental abnormality of the branchial apparatus, the incidence of which accounts for only 1% of all branchial cleft deformities; moreover, it often occurs on the left side. The anatomical position is often located in the cervical root and supraclavicular region, thus demonstrating cysts or sinuses adjacent to the thyroid gland. The diagnosis should be confirmed by anatomical location, imaging examination or laryngoscopy combined with postoperative pathological results and should be differentiated from cervical masses such as thyroglossal duct cysts and lymph node metastasis. The main treatment methods include surgical procedures and endoscopic cauterization of the internal fistula. The prognosis is generally good, and there is a risk of recurrence; however, cancer rarely occurs. Conclusion Deformity of the fourth branchial fissure is very rare; thus, it should be identified early to avoid excessive and ineffective surgical drainage, reduce potential complications during resection and completely remove the lesion to prevent recurrence.

First branchial cleft anomalies are rare. Its estimated incidence is one in 100,000. Clinically, patients present with recurrent otorrhea, periauricular swelling, and/or flowing fistula in the neck. Surgical removal of the tract is considered the best treatment option for the first branchial cleft fistula. Due to the close relationship between the fistula tract and the facial nerve branches, facial nerve injury is one of the not uncommon complications of this surgery. Different variations in the relationship between the fistula tract and the facial nerve trunk and its branches have been mentioned in the literature. In this study, we presented the case of an atypical course of the facial nerve in a nine-year-old pediatric patient who underwent first branchial cleft fistula surgery, and discussed the importance of anatomic variations and measures to be taken to prevent facial nerve injury.

Background: The pulse granuloma (PG) is believed to represent a distinctive foreign body reaction to ingested particles of legumes. Its presentation in the neck is entirely unexpected. Methods: A woman presented with a mass of the lower neck that recurred following incision and drainage. The recurrent mass was found to be associated with an open sinus tract at the apex of the left pyriform sinus. The opening of the sinus tract was closed and the cyst was removed. Results: Histologic examination of the neck mass showed vegetable material with an associated granulomatous reaction known as PG. Conclusions: The documentation of a PG arising in the neck would seemingly discredit the legume theory, but it only further supports it. Its association with a fourth branchial cleft cyst provides evidence for the existence of the complete fourth branchial cleft fistula with seeding of ingested material through sinus tract opening.

A complete second branchial fistula is very rare and has an internal opening at the tonsillar fossa and an external opening at the lower third of the sternocleidomastoid (SCM). Patients commonly present with persistent or intermittent mucoid or mucopurulent discharge from an external opening. The diagnosis is most often clinical and radiological investigations are rarely needed. Treatment of choice is complete surgical excision. The aim of this article is to aware young ENT surgeons of the various clinical and intraoperative surgical findings that can be encountered while dealing with these cases. This observational study was done for a period of 10 years. A total of 20 cases of fistula were included which intraoperatively had a complete track from tonsillar fossa to neck. Excision of the tract was carried out via combined transcervical and transoral approach under general anaesthesia using two incisions in stepladder pattern. Each patient was seen after one year of surgery to assess for any recurrence. Different findings of patients including age/sex at surgery, initial presentation, family history, laterality of the fistula tract, Intraoperative surgical findings, complications, and recurrences. were noted. Of the 20 patients, 13 (65%) were females and 7 (35%) were Females. Most common complaint was fistulous opening with intermittent discharge(15patients; 75%).Branchial cleft fistulae more commonly affected the right neck (14 patients, 78%) among unilateral cases and 2 patients (10%) had bilateral fistulae. No patient had associated congenital anomaly/syndrome, family history or and visible opening in tonsillar area. Glossopharyngeal nerve was identified in 12 cases and track was seen passing lateral to it except in one case. The internal opening of track was seen over posterior tonsillar pillar in 15 cases (75%) while in 5 patient the track was seen entering tonsillar tissue or bed. Tonsillectomy was done in 5 cases while not done in 15 cases where track was seen entering posterior pillar. All patients were seen at one year follow up. No recurrence was seen at one year of follow up. Complete second branchial cleft fistulae are rare. They are usually right sided and unilateral. The track passes between carotid bifurcation and invariably passes lateral to both glossopharyngeal and hypoglossal nerves. Track usually ends at the posterior tonsillar pillar. Tonsillectomy is not routinely indicated. Recurrences are not typically seen. [ABSTRACT FROM AUTHOR]

In the head and neck area, a large proportion of clinically relevant fistulas occur in childhood. The present case describes the use of contrast enhanced ultrasound with intraductal administration of the contrast medium for preoperative visualization of the fistula duct in the case of a second brachial cleft fistula. This provided the surgeon with important additional information, such as the detailed course of the fistula and its relation to the large vessels of the neck. The method can help to improve surgical planning, reduce radiation exposure and to avoid imaging under general anesthesia, especially in children. [ABSTRACT FROM AUTHOR]

Abstract Background Second branchial cleft fistulae are rare pediatric anomalies managed with surgical excision and, in certain cases, ipsilateral tonsillectomy to prevent postoperative recurrence or wound infection. Limited information is available in the published literature regarding surgical techniques to maximize patient outcomes and minimize recurrence. Our objective was to describe outcomes for the largest series of branchial cleft fistulae excised using a uniform technique based on embryologic principles. Methods We conducted a retrospective analysis of pediatric patients who underwent surgery for second branchial cleft fistula using a uniform technique developed by the senior surgeon between 2006 and 2018 at a tertiary care pediatric hospital. The technique involves dissection to the level of the greater cornu of the hyoid bone as the point of transection, which is the landmark for the base of the tonsillar fossa. Data collected included age at surgery, initial presentation, laterality of fistula tract, final pathology, and follow up data. Measured outcomes included fistula recurrence, wound infection, and other complications. Results Of 67 patients, 28 (42%) were male and 10 (15%) had bilateral fistulae, for a total of 77 tracts excised. After a median follow up of 31 months, there were no recurrences and one wound infection that was treated successfully with oral antibiotic therapy. No patients underwent tonsillectomy. Conclusion Effective management of second branchial cleft fistulae can be challenging. We present the largest cohort of results using a uniform surgical technique performed at a single center that obviates the need for tonsillectomy, and thus represents a less morbid and effective approach with no evidence of recurrence.

Branchial cleft fistulae are benign congenital tracts in the neck that connect the pharynx to the skin resulting from improper involution of the branchial apparatus. Surgical excision is the most common treatment. While alternative treatments exist, there is a paucity of literature detailing nonsurgical managements. We describe a branchial cleft fistula successfully treated with sclerotherapy to suggest this alternative management. A seven-week-old boy presented to our hospital with daily fluid drainage from a punctate skin opening at the anterior base of his neck. At one year of age, this was confirmed to be a second branchial cleft fistula and treated with sclerotherapy in Interventional Radiology (IR). The entire tract was catheterized from the skin opening to the pharynx and then sclerosed with doxycycline in an outpatient procedure under general anesthesia. There were no complications and his clinical symptoms resolved completely post-procedure suffering no recurrence as of his last follow-up 26 months later. This case demonstrates branchial cleft fistulae can be eradicated with sclerotherapy making it a clinically feasible minimally invasive alternative to surgical excision.

Branchiogenic carcinoma (BC) is an extremely rare and still controversial clinic entity with few cases reported in literature. This malignant squamous epithelial wall degeneration of a pre-existing second branchial cleft cyst (SBCC) was first described by Von Volkmann in 1882. Here we present a case of cervical cystic mass that was histologically diagnosed as a primary branchial cleft cyst carcinoma. This is the first documented cases of primary BC presenting with skin involvement on initial examination. [ABSTRACT FROM AUTHOR]

Objective: To provide the experience of diagnosis and treatment of second branchial cleft fistula in children. Methods: The clinical data of 76 children with second branchial cleft fistulas admitted to Beijing Children's Hospital affiliated with Capital Medical University from January 2016 to December 2020 were retrospectively analyzed. All patients underwent cervical ultrasonography and resection of the second branchial cleft fistula, and their clinical manifestations, surgical methods, complications, recurrence condition, and lesion appearance of the patients were analyzed. Results: Among the 76 cases, the lesions of 43 cases were on the right side, 20 were on the left side, and 13 were bilateral, for a total of 89 lesions. There were 49 type I lesions, 28 type II lesions, 8 type III lesions, and 4 type IV lesions. Type I and type II cases underwent complete excision of the fistula through a small incision in the neck; 2 cases of type III branchial cleft fistulas were treated with trapezoidal incision; 2 cases of type III branchial cleft fistulas underwent single transverse incisions; single small incision-assisted endoscopic resection was adopted in 4 cases of type III and 4 cases of type IV branchial cleft fistulas. During the follow-up period of 6 to 60 months, only 3 cases developed postoperative infection, the others had no postoperative complications, and no cases had recurrence during postoperative follow-up. Conclusion: The incision of the second branchial fistula should be selected according to imaging examination to achieve removal of the fistula while maintaining esthetics., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

We report a case of 32 year old male who presented to us with first branchial cleft anomalies on both sides with discharging cutaneous openings on the right side; and cystic swelling on the left side. High index of suspicion is required in such congenital cysts. Surgical exploration and excision is the definitive treatment of a collaural fistula. [ABSTRACT FROM AUTHOR]

The first branchial cleft (FBC) is an extremely rare occurrence, manifesting as cysts, sinuses or fistula. Among all branchial anomalies, FBC represents 8–10 % of branchial clefts. It accounts for about 17 % of all cervical masses in childhood. FBC can be caused by inadequate removal or closure of the ectoderm. The location of the fistula can be adequately determined by magnetic resonance imaging (MRI). We report three cases from the first branchial cleft fistula (FBCF) in our ENT Department with a good response to surgical treatment. Patients had an average of 24 months of follow-up. The aim of our study is to study the clinical manifestations, the diagnosis and the surgical management of the FBCF. An in-depth knowledge of the embryology of the neck and face will ensure early diagnosis and complete surgical resection of FBCFs, which will minimize the risk of severe complications including facial paralysis. FBC is rare and may present as a cyst or fistula. It is managed by surgical excision, leaving the tract cyst of the fistula intact with preservation of the facial nerve. • First branchial cleft is rare and may present as a cyst or fistula. • Diagnosis is confirmed by anatomopathological examination. • Treatment is surgical, and complete excision is necessary to prevent recurrence. • Identifying and protecting the facial nerve is essential.

Branchial cleft cysts present at varying ages; sometimes excision is delayed because of concern about operating in small children. Our goal was to determine if outcomes and complications differed among pediatric age groups. Retrospective, cross-sectional. American College of Surgeons' National Surgical Quality Improvement Pediatric database. Patients who underwent a branchial cleft cyst excision between 2016 and 2020 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Pediatric database. Patients with CPT code 42,815: 'excision branchial cleft cyst, vestige, or fistula, extending beneath subcutaneous tissues and/or into the pharynx' as their primary procedure were included. Variables of interest included patient demographics, comorbidities, pre-operative risk factors and complications. 2267 patients with median age of 3.9 (IQR: 7.4, range: 0.04–17.9) years were included. The most common pre-operative risk factors were 149 (7 %) patients with prematurity, 136 (6 %) with developmental delay, 135 (6 %) with congenital malformation, and 128 (6 %) with open wound or wound infection. 68 (3 %) patients experienced at least one post-operative complication, with 73 post-operative complications documented in total. Surgical site infections were the most common complications with 49 (67.1 %) superficial infections, 11 (15.1 %) deep infections, and 4 (5.5 %) organ/space infections. Surgical site infections were the most common reason for related readmission. Duration of anesthesia and operative time increased significantly as patient age increased (p <.001 for both). There was no significant correlation between age and complication incidence. Branchial cleft cyst excision is a relatively safe operation with a low complication rate, even in young pediatric populations. [ABSTRACT FROM AUTHOR]

In branchial lymphoepithelial cyst (BLEC), which is also known as branchial cleft cyst, the remnants of a branchial arch develop into a cyst, causing swelling. The first case of BLEC in the parotid gland was reported by Hildebrant in 1895. Since then, BLEC in the parotid gland has continued to be reported, but in rare cases. A 45-year-old man presented to our hospital with a swelling of the left cheek of approximately 6 months' duration. The patient underwent a superficial parotidectomy and was pathologically diagnosed with BLEC. Of note, this was the first case of non-human immunodeficiency virus (HIV)-related BLEC of the parotid gland in South Korea. BLEC is a benign condition, but its treatment depends on the presence of HIV infection. In HIV-negative patients, BLEC does not require a further work-up to evaluate metastasis. Our case report describes the diagnosis and treatment of BLEC in a patient without HIV. [ABSTRACT FROM AUTHOR]

• First branchial cleft fistula are rare and can be in form of cyst or fistula. • Clinically, they may masquerade as parotid tumours or as otitis with ear drainage. • Its management is surgical excision keeping the tract cyst of the fistula intact. • Superficial parotidectomy with facial nerve dissection is the key to complete excision of the cleft fistula with preservation of the facial nerve. First branchial cleft anomalies (FBCA) are rare. They have an estimated incidence of 1 in 100,000. Type I are those that embryologically duplicate the membrane (cutaneous) external auditory canal. The aim of this case is to describe an unusual path of a type II first branchial cleft fistula tract in a 3 years old child and its surgical management in the academic hospital of Casablanca. This case is about a 3 year old girl who presented to the Ear Nose Throat (ENT) consultation for recurrent right lateral cervical infection. Clinical examination found an unsightly scar attached to an orifice giving pus located near the right mandibular angle suggesting type II first branchial cleft anomaly. Surgical excision was performed under general anesthesia by the superficial parotidectomy approach, the facial nerve was identified and preserved. The fistula cord was dissected and followed, it went under the facial nerve and the parorid gland to end under the digastric muscle where we tied it up. The postoperative check-up did not show any complications. The follow-up period was 12 months; the clinical examination did not find any sign of recurrence. First branchial cleft fistula are rare and can be in form of cyst or fistula. Its management is surgical excision keeping the tract cyst of the fistula intact with facial nerve preservation.

Branchial cleft anomalies are the second most common head and neck congenital lesions in children. It may sometimes be a part of branchio-oto-renal (BOR) syndrome, so in patients with branchial cleft anomalies associated with a complaint of auricular deformity or a similar history and findings in other family members, we should take an additional examination to find the possibility of BOR syndrome. Complete excision is essential for good prognosis. For the management of branchial cleft anomalies, various methods have been reported. Endoscopically assisted dissection technique and transoral robot-assisted surgery were used in the management of fistula and allowed excellent visualization of the pharyngeal component of the lesion and a minimally invasive approach. It is essential for the surgeon to fully comprehend the congenital lesions to attain the correct preoperative diagnosis and plan for an appropriate surgical approach to prevent the most common complication and recurrence in these lesions. The following sections discuss the anatomy, common presentation, auxiliary examination, differential diagnosis, the current principles of surgical treatment and prognosis for second branchial cleft anomalies in children, and discussed the branchio-oto-renal syndrome.

Abstract Background Large-scale assessments of outcomes in thoracic endovascular repair (TEVAR) for thoracic aortic emergencies are lacking. We evaluated perioperative outcomes of TEVAR compared with open surgery among trauma patients in a large statewide database. Materials and methods We evaluated the California Office of Statewide Health Planning and Development 2007-2014 patient discharge database. Blunt-injured trauma patients with thoracic aortic emergencies were identified by International Classification for Diseases, Ninth Revision, Clinical Modification diagnosis codes and external cause-of-injury codes. Procedure codes were evaluated for TEVAR or open repair. Outcomes included mortality or complications during the index admission and readmission within 30 d. The association between both operative methods and each outcome was evaluated by two-level logistic regression adjusting for age, length of stay, admission year, trauma-related mortality probability, and comorbidity status. Results Among over 31 million hospitalizations, we identified 48,357 cases (0.2%) of thoracic aortic disease. Of these, 2159 (4.5%) were unique blunt-injured trauma patients of whom 336 (15.6%) underwent operative repair: 256 TEVAR (76.2%) and 80 (23.8%) open repair. Patients with open repair were older than TEVAR patients (mean age 52.0 versus 46.8, P = 0.038). There were no significant differences in race, sex, injury mechanism, mortality, or 30-d readmission by operative method. However, open repair was associated with greater odds for cardiac, spinal cord, and neurological complications. Conclusions Although mortality in trauma patients who underwent TEVAR was similar to that in patients with open repair, TEVAR was associated with fewer complications. This suggests that TEVAR offers clinical benefit over open repair in treating trauma patients with aortic disease. [ABSTRACT FROM AUTHOR]

Abstract Preoperative discrimination of solitary cervical branchial cleft cysts from cystic lymph node metastasis often is challenging. Surgical excision of the cystic formation and consecutive histopathological examination of tissue specimens are the only means resulting in the correct diagnosis. However, in case of malignancies surgery on the lateral neck prior to the definitive treatment is considered to negatively influence the patients' outcome. The rate of cystic lymph node metastasis in patients presenting with a lateral branchial cleft cyst, localization of the primary tumour and oncological outcome were investigated. Retrospective chart review of 131 patients presenting clinically with solitary lateral cervical cysts between. A malignant tumour was detected in 12 patients (9.2%). Malignant tumours were significantly more frequent in patients older than 40 years of age (22.0%; p = 0.0001). In patients older than 40 years of age with solitary lateral cervical cysts a malignancy should be presumed. [ABSTRACT FROM AUTHOR]

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.

An aortic aneurysm (AA) is a focal dilatation of the aortic wall. Occurrence of AA rupture is an all too common event that is associated with high levels of patient morbidity and mortality. The decision to surgically intervene prior to AA rupture is made with recognition of significant procedural risks, and is primarily based on the maximal diameter and/or growth rate of the AA. Despite established thresholds for intervention, rupture occurs in a notable subset of patients exhibiting sub-critical maximal diameters and/or growth rates. Therefore, a pressing need remains to identify better predictors of rupture risk and ultimately integrate their measurement into clinical decision making. In this study, we use a series of finite element-based computational models that represent a range of plausible AA scenarios, and evaluate the relative sensitivity of wall stress to geometrical and mechanical properties of the aneurysmal tissue. Taken together, our findings encourage an expansion of geometrical parameters considered for rupture risk assessment, and provide perspective on the degree to which tissue mechanical properties may modulate peak stress values within aneurysmal tissue.

Objective: Although second branchial cleft fistula (BCF) can be well treated with surgical excision, neck scarring is unavoidable. We previously reported chemocauterization with trichloroacetic acid (TCA) to close various fistulas. Here, we report chemocauterization of a second BCF without a consequent incision scar.Methods: This procedure was applied in four pediatric patients whose parents were reluctant to undergo surgical excision for a second BCF. Under general anesthesia, a thin metal suction tip or cut down tube was inserted through the skin opening. Normal saline with or without dye was injected to identify the pharyngeal opening around the palatine tonsil, and 75% TCA solution mixed with dye was injected. Leaked TCA at the pharynx was sucked out meticulously to avoid extensive and unexpected injury to the mucosa, and the external opening was sealed with a thin adhesive film.Results: There were no immediate complications and recurrence of a second BCF in all patients during the median follow-up of 23 months (range, 18-88 months) with minimal neck scarring.Conclusion: TCA chemocauterization of second BCF could be a simple, less invasive, and feasible treatment option in pediatric patients.

The objective of this study is to make a clinical analysis for first branchial cleft anomalies (FBCAs), especially introduce the relationship between the Type I/II FBCA with the facial nerve and to demonstrate the importance of using intraoperative microscope and facial nerve monitoring. This is a retrospective review of patients with FBCAs treated in Beijing Children's Hospital, from Jan 2013 to Dec 2015. Clinical data of patients, including sex, age, chief complains, history of surgery, incision and drainage, the relationship with the facial nerve, pre and post-operative facial paralysis, recurrent rate and complications were recorded. FBCAs were divided into two subtypes according to Work's Classification. All patients had an MRI examination for diagnosis and to locate the lesions before surgery. Both microscope and facial nerve monitors were routinely used for detecting and protecting the facial nerve. The study cohort included 42 patients with ages ranging from 10 months to 14 years. The chief complaint was recurrent swelling or abscess near the ear or angle of mandibular. 76.2% of them (32/42) had incision and drainage histories. Two of them had suffered from facial palsy during the infectious period. Seven patients had undergone surgeries once or twice in other hospitals. Four patients with Type II FBCAs developed temporary facial palsy. We had follow-ups for each patient from 3 months to 3 years. 4 (9.5%) patients with Type I FBCA had got postoperative external auditory canal (EAC) stenosis. There were no cases of recurrence. Type II FBCAs has closer relationship with facial nerve than Type I FBCAs. The facial nerve of Type II FBCAs may lie more superficially and ascending to the fistula. Intraoperative microscope and facial nerve monitoring were necessary for protecting the facial nerve and decreasing the recurrent rate. [ABSTRACT FROM AUTHOR]

Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by the coexistence of branchial cysts or fistulae, external ear malformation with pre-auricular pits or tags, hearing impairment and renal malformations. However, the presence of the main features varies in affected families. Here, we present a 16-yearold boy admitted to the Department of Nephrology at the Pediatric Clinic, University Clinical Center of Kosovo, Pristina, Republic of Kosovo because of severe renal insufficiency diagnosed 6 years ago, which progressed to end-stage renal failure. Clinical examination on readmission showed a pale, lethargic and edematous child, with auricular deformity, pre-auricular tags and pits as well as bilateral branchial fistulae. Laboratory tests revealed high blood urea nitrogen (BUN) 15.96 mmol/L and serum creatinine 633.0 μmol/L; low glomerular filtration rate (GFR) 12 mL/min./ 1.73 m2 and massive proteinuria 4+. Abdominal ultrasound showed bilateral kidney hypoplasia. A novel mutation of the EYA1 gene was confirmed. Daily hemodialysis is continuing until renal transplantation is done. This case is presented to increase awareness among general practitioners to consider BOR syndrome or other renal abnormalities in patients with branchial fistula and/ or external ear anomalies or similar findings in other family members.

Background: Branchial cleft anomalies constitute a frequently encountered and commonly non-lethal disease in otolaryngology, and result from aberrant embryonic development. The third branchial cleft fistula is one of the four known specific types of branchial cleft anomalies, and always presents as recurrent neck abscess and suppurative thyroiditis. Here, we report an unexpected death due to severe neck infection following a third branchial cleft fistula. Case presentation: A 19-year-old man was sent to the hospital with a 1-week history of recurrent left-sided neck abscess, and was scheduled for incision and drainage of the abscess. However, before the surgery was performed, the man's condition deteriorated and he died. A review of his medical history showed that he had undergone a previous incision and drainage for a neck abscess 2 years ago. Postmortem examination revealed that the fatal neck abscess was induced by a third branchial cleft fistula. Conclusions: We conclude that a histopathological examination of neck tissue combined with a detailed review of medical history and examination of ultrasonographic and CT images can provide a rapid and accurate diagnosis of third branchial cleft fistula. This common, non-lethal disease can potentially lead to death if the neck infection is not properly diagnosed and treated. In medico-legal practice, medical examiners should be aware of this condition, as this knowledge would be important in the diagnosis of the cause of death. [ABSTRACT FROM AUTHOR]

Summary A 7-year-old warmblood mare showed sudden onset of mild intermittent haemoptysis. Clinical examination revealed no significant abnormalities. Haematological examination showed mild anaemia, hypoalbuminaemia and neutrophilia. Coagulation tests were normal. Endoscopic examination revealed unilateral pulmonary haemorrhage with blood clots in the bronchi and trachea. Treatment with antibiotics was started and the horse was given stable rest. Two weeks later, the horse was found dead with blood and frothy sputum leaking from the nostrils. Post-mortem examination revealed a large thoracic aortic aneurysm communicating with a pseudoaneurysm that had formed a fistula into a right bronchial branch. Microscopical examination of the aneurysm showed extensive medial fibrosis with prominent degeneration, fragmentation and mineralization of the elastic fibres and deposition of mucoid material in the tunica media. The pseudoaneurysm was lined by collagen bundles admixed with fibroblasts and a small amount of adipose tissue. Aortobronchial fistula is a rare condition in man that is usually associated with primary aortic pathology, most often aneurysms. To the authors' knowledge this is the first case of a fatal aortobronchial fistula in a horse or any other animal species. [ABSTRACT FROM AUTHOR]

Background Congenital cervical salivary duct fistulae are rare entities and can mimic branchial cleft fistulae. Ectopic salivary tissue associated with these pharyngocervical tracts may have malignant potential. Methods and Results We present a case report of a novel surgical approach and review of the literature. A 27-year-old man presented with complaint of drainage from the right side of his neck since early childhood. A tract was found from the posterior tonsillar pillar into the neck and ectopic salivary tissue was found along the tract. A congenital hearing loss was also present. Transoral robotic (TORS)-assisted surgery was used in the management of this patient and allowed excellent visualization of the pharyngeal component of the lesion and a minimally invasive approach. The patient did well with no recurrence. Conclusion TORS was helpful for management of a congenital salivary fistula and may be helpful for branchial cleft fistulae. These lesions may be associated with the branchio-oto-renal (BOR) syndrome. © 2015 Wiley Periodicals, Inc. Head Neck 38: E49-E53, 2016 [ABSTRACT FROM AUTHOR]

Pyriform sinus fistula (PSF) is an anomaly that can arise due to failure of involution of the third or fourth branchial cleft during embryogenesis. It can manifest clinically as sinuses, cysts, or abscesses in the neck and is common in childhood. Herein, we describe a neonate who presented with neck swelling and respiratory distress, which was secondary to a fourth branchial pouch sinus. Physical examination revealed swollen areas in the posterolateral pharyngeal wall and on the external left side of the neck. Computed tomography imaging showed a left-sided mass that was filled with air and fluid. Eventually, the pyriform sinus cyst and the entire fistulous tract were excised. The postoperative course was uneventful. Follow-up after 18 months showed no recurrence. [ABSTRACT FROM AUTHOR]

Background. First branchial cleft anomalies (FBCA) are rare clinical entities of the head and neck. Typically, the tract of the FBCA begins in the external auditory canal and ends in the postauricular or submandibular region. Case Presentation. We present a case of a 23-year-old man who had a first branchial cleft fistula with atypical opening on the root of the helical crus. Complete excision of the tract, including the cuff of surrounding cartilage, was performed. Histopathology revealed a fistular tract lined with squamous epithelium. To our knowledge, this is the first case to be reported of type I FBCA with an opening on the root of the helical crus. The low incidence and varied presentation often result in misdiagnosis and inappropriate treatment. Conclusions. In the patients with FBCA, careful recognition of atypical variants is essential for complete excision. [ABSTRACT FROM AUTHOR]

Objectives A fourth branchial pouch remnant is well known as a pyriform sinus fistula. However, there has been no report of a fistula composed of the complete remnant of the fourth branchial apparatus. We experienced patients with a congenital lower neck cutaneous fistula which was thought to be the skin-side remnant of the fourth branchial cleft. Materials and methods Seven children were referred to our hospital from 2009 to 2015 for the treatment of a cutaneous fistula situated near the sternoclavicular joint. All of them were surgically resected and their pathological characteristics were examined. Clinical charts were retrospectively reviewed. Results In six cases, the left side was affected. All cutaneous fistulas had a small skin orifice near the sternoclavicular joint and they were situated at the anterior edge of the sternocleidomastoid muscle. Abscess formation was seen in four cases. Surgical resection was performed at the age of 6 months to 9 years. These fistulas ran deep into the subcutaneous tissue and had a blind end. Pathological examination showed that the epithelial layer was mainly composed of a stratified squamous epithelium. In two cases the epithelium was composed of ciliated columnar epithelium. Recurrence has not been observed in any of the cases. Conclusion The seven cases had a common clinical feature and were a definite clinical entity. Judging from the characteristics of our cases and the previous literature, we concluded that this lower neck cutaneous fistula was most likely a congenital skin-side remnant of the fourth branchial cleft.

Objective To share our experience involving seven patients with type II first branchial cleft anomalies (hereafter, type II anomalies), to determine whether the location of the external fistula openings of the anomalies are associated with the location of the facial nerve tract, and elucidate the relationship between the location of the fistula opening and the facial nerve. Methods The medical records of seven patients who underwent surgery from 2005 to 2013 for type II anomalies were retrospectively examined. The relationship between the fistula opening and the facial nerve was evaluated in each patient with respect to whether the fistula opening was superior or inferior to the mandibular angle. All patients underwent partial parotidectomy, facial nerve exposure, and total excision of the mass together with connection of a small cuff of the external auditory canal skin to the fistula tract. Results The fistula tracts were located medially to the facial nerve in two patients, and both fistulae had openings inferior to the mandibular angle. The fistula tracts were located laterally to the facial nerve in the remaining five patients: one patient had no external opening, one had an opening inferior to the mandibular angle, and the remaining three had openings superior to the mandibular angle. Conclusion Because type II anomalies are rare, their diagnosis is difficult. Surgery of such lesions is challenging and associated with a high risk due to their proximity to the facial nerve. We believe that the location of the fistula opening may help to identify the relationship between the anomalous lesion and facial nerve. Studies involving larger series of cases are needed to confirm our hypothesis; however, because of the rarity of this specific anomaly, it will not be easy to compile a large number of cases. We believe that our study will encourage further investigation on this subject. [ABSTRACT FROM AUTHOR]

INTRODUCTION 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. METHODS 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. RESULTS 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. CONCLUSION 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. [ABSTRACT FROM AUTHOR]

The goal of this case report is to describe an unusual case of recurrent first branchial cleft fistula with cysts and the effective surgical approach of complete removal with preservation of the facial nerve. A 27-year-old woman presented to our clinic after unsuccessful removal twice during the last 20 years. We have achieved satisfactory outcomes by using an approach to identify the facial nerve at the stylomastoid foramen with canal wall up mastoidectomy under a microscope. No sign of facial palsy, hearing loss, or recurrence were noted in postoperative follow-up. This approach might facilitate the complete dissection of scar and lesions of recurrent first branchial cleft anomalies around the main trunk of the facial nerve in the parotid gland.

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.

Thyroglossal duct cysts followed by branchial cleft anomalies are the most common congenital neck masses encountered in practice, second branchial cleft cysts and sinuses are the most common type (LaRiviere and Waldhausen in Surg Clin North Am 92(3):583-597, 2012). Although both abnormalities are common individually, but rarely seen associated in same patient as described in our case. Congenitalcervical anomalies are important to consider in the differential of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies. A synchronous presentation of both type of cyst and fistula in a same child patient is very rare with no such cases reported in literature till date. [ABSTRACT FROM AUTHOR]

First branchial cleft anomalies are a special group of congenital malformations that represent <10% of all branchial cleft anomalies. They may present as cysts, swellings, or fistulas in the periauricular region or in the lateral aspect of the neck. Failure to identify these lesions can lead to delay in the diagnosis, often misdiagnosis, inadequate treatment, and subsequent recurrence. We report a case of 15-year-old girl who presented with recurrent postauricular cyst. Fine-needle aspiration biopsy was performed, and it was diagnosed as infected cystic lesion. On histopathological examination, the diagnosis was confirmed as first branchial cleft cyst. [ABSTRACT FROM AUTHOR]

Introduction: First branchial cleft anomalies manifest with duplication of the external auditory canal. Case Report: This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a sinus in the helical root, may explain this feature. A canal wall down mastoidectomy with canaloplasty and wide meatoplasty was performed. The branchial cleft was excised through parotidectomy and facial nerve dissection. Conclusion: It should be considered that canal stenosis in such cases can induce cholesteatoma formation in the auditory canal and middle ear. [ABSTRACT FROM AUTHOR]

Abstract: Anomalies of the first branchial cleft (FBC) are uncommon, and recognizing them can be difficult. Although present at birth, many cases do not become evident until later in childhood or adolescence, with an initial clinical presentation in adulthood being encountered only rarely. Typically, FBC anomalies present as a unilateral cyst, sinus, or fistula associated with the external auditory canal, or with swelling or an inflammatory opening in the peri-auricular/parotid area. They are commonly misdiagnosed and are often treated inadequately before being excised completely. A 40-year-old woman presented to the maxillofacial outpatient clinic with an episode of bilateral pre-auricular tumefaction, initially diagnosed as temporomandibular dysfunction syndrome. This was associated with bilateral pre-auricular pain that increased with mandibular movements. In relation to the patient's history, and given the bilateral presence of a pre-auricular pit, a diagnosis of FBC anomaly was made. Further investigation showed a related asymptomatic history in five other cases across four generations of the same family. The authors describe here the case, the diagnostic methodology, and the wide local excision technique used for removal of the branchial sinus. [Copyright &y& Elsevier]

The aim of the present study was to assess the atypical imaging manifestations of branchial cleft cysts (BCCs) confirmed by pathology. Computerized tomography (CT) or magnetic resonance imaging (MRI) of 17 BCC cases were reviewed. The imaging features, including laterality, location, border, attenuation and internal architecture, were evaluated. All 17 cases were second BCCs, including 5 cases of Bailey type I classification cysts and 12 cases of type II classification cysts. The atypical imaging features included signal and morphological abnormalities. The abnormal signal intensities were caused by intracapsular bleeding (n=2) or solidification of cystic fluid (n=2). Intracystic hemorrhaging revealed homogeneous hyperintensity on T1 -weighted image (T1WI) and T2-weighted image (T2WI). Solidification of cystic fluid revealed slightly homogeneous hyperintensity compared with muscle on T1WI and homogeneous hypointensity on T2WI without enhancement. The aberrant morphology mainly presented as thickening of the cystic wall (n=13). Thickened walls of BCCs with ill- (n=5) or well- (n=8) defined borders were observed in 13 patients. In 3 patients, significant enhancement was identified following intravenous gadolinium administration (n=4). When with atypical CT or MRI features are presented, the typical location of BCCs can help in the diagnosis, as it is located at the lateral portion of the neck adjacent to the anterior border of the mandibular angle or sternocleidomastoid muscle. The atypical observations, including variable signals, imply that the cystic content has changed. Thickened walls indicate inflammation or cancerous tendency and patients with ill-defined margins, vascular involvement or lymphadenopathy atelectasis indicate malignant conversion.

First branchial cleft (FBC) anomalies are uncommon. The aim of this retrospective clinical study is to describe our experience in dealing with these sporadically reported lesions. Eighteen cases presenting with various FBC anomalies managed surgically during an 8-year period at a tertiary referral medical institution were included. Ten were males (56 %) and eight females (44 %) with age range 3-18 years. Anomaly was right-sided in 12 cases (67 %). None were bilateral. Nine patients (50 %) had prior abscess incision and drainage procedures ranging from 1 to 9 times. Two also had previous unsuccessful surgical excisions. Clinical presentations included discharging tract openings in external auditory canal/conchal bowl ( n = 9), periauricular ( n = 6), or upper neck ( n = 4); cystic postauricular, parotid or upper neck swellings ( n = 5); and eczematous scars ( n = 9). Three distinct anatomical types were encountered: sinuses ( n = 7), fistulas ( n = 6), and cysts ( n = 5). Complete surgical excision required superficial parotidectomy in 11 patients (61 %). Anomaly was deep to facial nerve (FN) in three cases (17 %), in-between its branches in two (11 %) and superficial (but sometimes adherent to the nerve) in remaining cases (72 %). Continuous intraoperative electrophysiological FN monitoring was used in all cases. Two cases had postoperative temporary lower FN paresis that recovered within 2 months. No further anomaly manifestation was observed after 49.8 months' mean postoperative follow-up (range 10-107 months). This study has shown that awareness of different presentations and readiness to identify and protect FN during surgery is essential for successful management of FBC anomalies. Intraoperative electrophysiological FN monitoring can help in that respect. [ABSTRACT FROM AUTHOR]
