Branches of the RLN and ITA

The relationship between the RLN and ITA is highly variable [105]. A particularly high-risk situation occurs when the ITA is divided into many ramifications close to the RLN and the branches of both structures intertwine [105]. Some nerve injuries can be caused by clamping or electrocauterization in an attempt to stop bleeding. Sometimes, the RLN can run parallel to a branch of the ITA, and visual misidentification can occur if the RLN is partially exposed (Fig. 14.5) [105].

A particularly high-risk situation is when the ITA is also divided into many ramifications close to the RLN, and the branches of both structures intertwine. We recommend that the RLN should be identified and followed through Berry’s ligament until the nerve enters the larynx
