• A first branchial cleft anomaly is an unusual clinical condition and the clinical picture is similar to that seen in other much more common diseases. This combination may result in a diagnostic delay and insufficient and dangerous primary surgery, resulting in facial nerve damage

• These anomalies form because of abnormal development of the first branchial cleft, found between the first and second branchial arches during the fourth and fifth weeks of gestation. First branchial cleft lesions arise specifically from the ventral portion of the first cleft 5, which like the other branchial clefts generally obliterates by week 8

Embryological anomalies of the first branchial cleft are uncommonly encountered. They usually present as cysts, swellings, or fistulas in the pre-auricular or post-auricular area or high in the neck, which may become infected. Failure to recognise these unusual cases may result in misdiagnosis, inadequate treatment, and subsequent recurrence First branchial cleft anomalies accountfor only 1-8% ofall branchialanomalies.Several classificationsystems have been proposed to aid in the diagnosis ofthese defects. We present a series of 12 patients with first branchial cleft anomalies classified according to ana­ tomic criteria.

First branchial cleft anomalies are a special group of congenital head and neck malformations First branchial cleft anomalies (BCAs) constitute a rare entity with variable clinical presentations and anatomic findings. Given the high rate of recurrence with incomplete excision, identification of the entire tract during surgical treatment is of paramount importance

First branchial cleft anomalies

First branchial cleft anomalies (FBCAs) are the most infrequent malformations that occur during the development of the branchial apparatus, appearing in less than 8% of all branchial anomalies. Traditionally, they are classified into Work type I and II, depending on their origin Surgical exploration revealed a first branchial cleft anomaly, splaying the superior and inferior branches of the facial nerve. The sinus tract in the neck turned out to be a second branchial cleft anomaly that was unrelated to the first branchial cleft. Figure 5 A first branchial cleft anomaly forms from the incomplete closure of the ventral portion of the first branchial cleft. These anomalies may present as cysts, sinuses, or fistulas, depending on the degree of cleft closure. A cyst is an encapsulated, epithelium-lined sac without any connections to the external environment

In particular, emphasis has been placed on the very close yet variable relationship.
3. First branchial cleft anomalies arise due to incomplete closure of the ectodermal portion of the first branchial cleft. Whether the defect is a fistula, sinus, or cyst depends on the degree of the closure. The most common head and neck manifestation is swelling in the periauricular (24%), parotid (35%),.
4. The first branchial cleft anomaly, caused by the unusual residue of the cleft epithelium, is relatively uncommon and accounts for less than 1 to 10% of all branchial anomalies .

5. Among the first branchial anomalies, seven (20.59%) cases belonged to Work II, while six (17.65%) cases belonged to Work I (according to the Work classification). Second branchial arch anomalies were seen in 17 cases (50%). Of these, branchial cyst constituted eight (26.53%) cases while branchial fistula constituted nine (26.47%) cases
6. First branchial cleft anomalies (FBCA) are rare in the clinical setting, as they account for 1 to 8% of all branchial abnormalities.

This retrospective study included 30 cases of FBCA in children managed from 2009 to 2016
7. Introduction. First branchial cleft anomalies are considered to be rare and make up about 10% of the branchial cleft anomalies encountered 1,2.They can present in variable locations, from the retroauricular and parotid region to below the mandible and above the hyoid bone 3.In view of their rarity, the physician needs to have a high index of clinical suspicion when dealing with cysts around.

2. During 4th week of embryonic development, five branchial arches grow into distinct parts of head and neck. All consist of arteries, nerves, muscle, skeletal tissue. If arches fail to fuse--> soft tissue anomaly on lateral neck may form, called branchial cleft anomaly. Anomalies include cysts (most common), fistulas, sinus tracts
3. 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.
4. First branchial cleft anomalies usually come to the clinician's attention because of an external opening or recurrent infections. For the safe and complete resection, a thorough understanding of the interrelationship of the anomaly to the facial nerve and identification of the facial nerve at the operative field is required

1. INTRODUCTION. The branchial cleft's embryological journey begins between the first 3-8 weeks of intrauterine life. Five mesodermal arches form by the inpouching of ectodermal clefts and endodermal pouches; however, incomplete obliteration of these clefts result in anomalies such as cervical lymphoepithelial cysts, branchial cysts, sinus tracts, or fistulae. 1,2 The occurrence of branchial.

4. Branchial cleft cysts, also known as branchial cleft anomalies, are congenital anomalies arising from the first through fourth pharyngeal pouches. These anomalies can exist as true fistulae, cysts, or sinus tracts, depending on the degree of incomplete obliteration during embryogenesis
5. Branchial cleft cysts and sinus tracts are congenital anomalies, meaning they result from an unexpected change in the womb before birth. Although most commonly unilateral (occurring on one side of the neck), they can be bilateral (both sides of the neck). When bilateral, they can be associated with other congenital anomalies

A branchial cleft abnormality is a cluster of abnormally formed tissue in the neck. A branchial cleft abnormality is a birth defect. It happens when the area doesn't form as it should during the early stages of an embryo's development HFM: OMIM 164210. HFM is a common facial birth defect involving the first and second BA structures and ranks second in prevalence only behind facial clefting. 11 Males are affected more frequently than females. About 45% of patients have affected relatives, and 5%-10% have affected siblings. 12 The phenotype is highly variable. There may be cardiac, vertebral, and central nervous system. An unusual cause of parotid tumors is the embryologic remnant of first branchial cleft cysts. Though all these anomalies fall in the domain of the surgeon, the presentation may be cutaneous.

First branchial cleft anomalies (FBCAs) are rare congenital defects that account for less than 8-10% of all branchial cleft anomalies and arise due to incomplete closure of the ventral portion of the first and second branchial arches [1, 2].A number of classification systems have been developed in an attempt to assist preoperative assessment and surgical planning for FBCAs A branchial cleft cyst is a cyst as a swelling in the upper part of neck anterior to sternocleidomastoid.It can, but does not necessarily, have an opening to the skin surface, called a fistula.The cause is usually a developmental abnormality arising in the early prenatal period, typically failure of obliteration of the second, third, and fourth branchial cleft, i.e. failure of fusion of the.
