The clinical presentation of branchial sinuses arising from the piriform fossa is more in keeping with derivation from the thymopharyngeal duct of the third pouch than the hypothetical course of third and fourth branchial fistulae.
Nine patients were diagnosed with first branchial fistulae or sinuses, 2 with second branchial fistulae, and 4 with third or fourth branchial fistulae. In this nude of first cleft anomalies, we had one complication temporary marginal mandibular nerve weakness. All rights reserved. Fifteen patients with confirmed branchial fistulae or sinuses who had undergone CT fistulography were included.
Surgical excision of second branchial cleft anomalies is the treatment of choice without any complications and with no recurrence.
In this series, we had 80 patients 38 female and 42 male. Knowledge of embryology and the related anatomy of the branchial apparatus is crucial in the identification of the type of branchial anomaly. Treatment in all cases consisted of complete excision. The authors believe that the diagnosis of branchiogenic carcinoma should never be accepted until repeated examinations over a period of at least five years have failed to reveal a primary tumour.
Of the 30 branchial anomalies, 7 In addition, seven children had 8 There was inadequate information on the remaining 3 The incidence of second branchial anomalies appears to be lower in our Asian nude population, while that of third and fourth branchial anomalies was higher. Chondrichthyans also exhibit natural variation with respect to branchial ray distribution—elasmobranchs sharks and batoids possess a series of ray -supported septa on their hyoid and gill arches, whereas holocephalans chimaeras possess a single hyoid arch ray -supported operculum.
Preoperative direct laryngoscopy always revealed a pit within the apex of the piriform fossa. Amongst this group, 15 patients had first branchial cleft anomaly, 62 had second branchial cleft anomaly and 3 had fourth branchial pouch anomaly.
The surgical approach needs to be tailored to the type. There were 22 branchial cysts, 31 branchial sinuses and 16 branchial fistulas. We identified 17 cases of third and fourth branchial anomalies, the largest series of its kind reported to date. The distribution of the lesions, internal openings, and neighboring relationship with parotid gland, carotid sheath, and submandibular gland could be clearly demonstrated on CT cross-sectional or volume-rendering images.
Comparison of the structure and composition of the branchial filters in suspension feeding elasmobranchs. Ninety-seven pediatric patients who were treated for nude anomalies over a year period were reviewed. Branchial anomalies were classified based on the of the review. Branchial cleft cysts were the most common type of second branchial cleft anomalies.
Two children had bilateral branchial anomalies requiring excision. The embryology, anatomy and pathology of branchial cleft anomalies are discussed and 87 cases reviewed. The presence and location of the lesions could be seen on x- ray fistulography. Among 25 patients with second branchial cleft anomalies, in 23 patients All patients of second branchial cleft anomalies were treated surgically under general anesthesia.
The most frequent anomaly was branchial cleft cyst, of which there were 77 cases. We reviewed the institutional and departmental databases at our institution to identify all cases of third and fourth branchial anomalies encountered from to All patient records were examined with respect to demographics, clinical history, and radiologic and pathologic reports. CT fistulography could provide nude information and benefit surgical planning by demonstrating the courses of branchial anomalies in detail.
We conducted a retrospective study at a tertiary care pediatric hospital. A total of 28 children underwent surgery for 30 branchial anomalies during the review period. Recurrence rates are increased when there are multiple preoperative infections and when there is no epithelial lining identified in the specimen. Here we report a case of complete congenital branchial fistula with an internal opening near the nude fossa. Correct diagnosis is essential to avoid inadequate surgery and multiple procedures.
The incomplete branchial fistula is not an uncommon congenital anomaly of branchial apparatus but a complete one is rare. The preoperative and postoperative diagnoses differed in 17 cases. Excision presented little difficulty. In the vast majority, the tract extended through the carotid bifurcation and extended up to pharyngeal constrictor muscles.
Branchial cleft anomalies are the second most common head and neck congenital lesions seen in children. None of the excised specimens that contained a cystic lining recurred; all five recurrences had multiple preoperative infections. In this subgroup, we had two complications one patient developed a seroma and one had incomplete excision. No proved case of branchiogenic carcinoma has been found in the Toronto General Hospital.
The diagnoses were confirmed by clinical, radiologic, or histopathologic examinations. Multidetector computerized tomographic fistulography in the evaluation of congenital branchial cleft fistulae and sinuses. Branchial Cleft Anomalies. All the first cleft cases were operated on by a superficial parotidectomy approach with facial nerve identification.
Here we show that the elongate hyoid rays of the holocephalan Callorhinchus milii grow in association with sustained Shh expression within an opercular epithelial fold, whereas Shh is only transiently expressed in the gill arches. We sought to review the presentation, evaluation, and treatment of branchial anomalies in the pediatric population and to relate these findings to recurrences and complications.
Five cases are described in which the original diagnosis was branchiogenic carcinoma—in four of these a primary tumour has already been found. Patients with cysts presented at a later age than did those with nude anomaly fistulas or sinus branchial anomalies. Fistula formation was iatrogenic, secondary to incision and drainage. No recurrence of second branchial cleft anomalies was observed.
Preoperative FNAC is a useful and accurate method for preoperative evaluation of branchial cleft cysts. All children who underwent surgery for branchial cleft sinus or fistula from January to December were included in this study. No lesions following the classical course of a either a third or fourth branchial anomaly were identified.
This article analyzes all the cases of branchial cleft anomalies operated on at Great Ormond Street Hospital over the past 10 years. Patients were studied if they underwent surgical treatment for the branchial anomaly and had 1 year of postoperative follow-up; 67 children met criteria, and 74 anomalies were studied. Coincident with this transient Shh expression, branchial ray outgrowth is initiated in C.
This is in contrast to the condition seen in sharks, nude sustained Shh expression corresponds to the presence of fully formed branchial rays on the hyoid and gill arches. Branchial anomalies in the pediatric population. Holocephalan embryos provide evidence for gill arch appendage reduction and opercular evolution in cartilaginous fishes. PubMed Central. Sinograms were helpful in demonstrating these lesions.
METHODS This was a retrospective chart review of all paediatric patients who underwent surgery for branchial anomalies in a tertiary paediatric hospital from August to November The nude branchial fistula: A case report. The age at the time of operation varied from 1 year to 14 years.
Gillis, J. Andrew; Rawlinson, Kate A. Chondrichthyans possess endoskeletal appendages called branchial rays that extend laterally from their hyoid and gill-bearing branchial arches. Branchial anomalies in children. Branchial ray outgrowthlike tetrapod limb outgrowthis maintained by Sonic hedgehog Shh aling.
The lesions were predominantly left sided, all presenting with neck infection. In the 62 children with second branchial cleft anomalies, 50 were unilateral and 12 were bilateral.
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. Majority of these cases were operated on through an elliptical incision around the external opening. There are three distinct types, first cleft, second cleft and fourth pouch anomaly.

Considered in light of current hypotheses of chondrichthyan phylogeny, our data suggest that the holocephalan operculum evolved in concert with gill arch appendage reduction by attenuation of Shh-mediated branchial ray outgrowthand that chondrichthyan branchial rays and tetrapod limbs exhibit parallel developmental mechanisms of evolutionary reduction.
In limbs, distal endoskeletal elements fail to form in the absence of nude Shh aling, whereas shortened duration of Shh expression correlates with distal endoskeletal reduction in naturally variable populations. The objective of this study was to review the clinical characteristics and surgical treatment outcomes of second branchial cleft anomalies, and to evaluate the usefulness and accuracy of preoperative fine-needle aspiration cytology FNAC in the diagnosis of branchial cleft cysts.
Surgical excision involved ipsilateral thyroidectomy as the lesion passed through the thyroid gland. Branchial anomalies are relatively common in children.
Distribution of branchial anomalies in a paediatric Asian population. Branchial sinus of the piriform fossa: reappraisal of third and fourth branchial anomalies. The aim of this study was to primarily investigate the usefulness of computerized tomographic CT fistulography in the diagnosis and management of branchial cleft fistulae and sinuses. The objective of this study was to review clinical and embryologic aspects of third and fourth branchial anomalies.
There were five cases of external branchial sinus and five cases of complete branchial fistula. The internal openings, distribution, and neighboring relationship of the lesions presented by CT fistulography were analyzed to evaluate the usefulness in comparison with x- ray fistulography.
The three patients with fourth pouch anomaly were treated with endoscopic assisted monopolar diathermy to the sinus opening with good outcome. Complete excision was achieved in all second nude cases except one who required a repeat excision.
Complete excision was achieved in all these first cleft cases.
