This study aims to identify all types of congenital neck deformities called " webbed neck ". Through a literature survey, the researcher selected 27 articles describing the surgical treatment of the webbed neck, but without considering the varieties of this deformity. For this reason, the researcher studied all the reported cases from which she developed a classification containing 4 types of webbed necks allowing the use of the most suitable technique to enhance the surgical outcomes.

Through a literature survey of 27 selected articles (from PubMed database and clarivate web of science). The publication years ranged from 1937 to 2020 and the number of patients reported to have undergone surgery was 78 patients.

The webbed neck is a noticeable congenital deformity mainly observed in Turner syndrome. It consists of a bilateral fold extending from the mastoid to the acromion with several distinctions as described in Mehri Turki's webbed neck classification as follows:

Type 1: The fold is maintained by a fibrotic band and the posterior skin is abnormally hairy with a low hairline placement.

Type 2: There is no fibrotic band and the hair abnormality exists as in Type 1

Type 3: There is a fibrotic band and a low posterior hairline but the posterior skin is hairless

Type 4: The fold is maintained by a fibrotic band without hair abnormality

It appears that according to the type of webbed neck, the surgical approach and surgical steps and technique will be adapted to what will be corrected. This classification is therefore crucial to guide surgeons towards the most suitable technique allowing the best results.

Inclusion Criteria:

• Articles with a detailed description of the surgical technique
• Articles reporting post-operative results
• Articles written in English or French

Exclusion Criteria:

• Articles with incomplete descriptions of the webbed neck
• Articles without iconography

The study is about 78 patients reported in the literature, aged between 2 and 30 years and born with a webbed neck (or pterygium colli)
