[Cervical cysts of second branchial arch. Retrospective study of 14 cases]. / Quistes cervicales de segundo arco branquial: estudio retrospectivo de 14 casos.

Fourteen patients with lateral neck branchial cysts treated over an 18 year term were reviewed to analyze the authors' method of diagnosis and management. The possibility of an embryologic rest in the neck should therefore be kept in mind with all clinically evident neck masses. Histopathological examination revealed that cysts were lined with a stratified squamous epithelium. Computed tomography and fine-needle-aspiration currently are essential diagnostic methods in the study protocol of these lesions. Traditional surgical techniques for the management of branchial remnants rely on simple excision of the structures associated with the sinus tract, with dissection carried out in the plane between the branchial remnant and the normal anatomic structures of the neck. Initial surgery is crucial since the recurrence rate after incomplete surgery can be as high as 22%.

[Granular cell tumor. A lingual case report]. / Tumor de células granulares. A propósito de un caso lingual.

Although the origin of granular cell tumor (GCT) is no totally clarified, a neurogenic source is generally accepted. Some think its forerunners are the Schwann cells. Despite the tongue's localisation is frequently seen, few are the papers dealing with this topic. We report the case of a patient suffering a granular cell tumor of the tongue and profit the opportunity to reconsider the followings items: clinical findings, examination, diagnosis, histology and management and course of these growths. Literature's review of the theme.

[Evaluation of informed consent in ear, nose, and throat practice]. / Valoración del consentimiento informado en ORL.

[Protruding jugular bulb. A review of 7 cases]. / Golfo yugular procidente. Revisión de siete casos.

The position of the jugular bulb varies greatly. A high jugular bulb procident from the temporal bone is not uncommon. Most people with this anatomic variation remain asymptomatic. We report seven cases of high jugular bulb with clinical manifestations. The anatomy, clinical manifestations, diagnosis, and management are reviewed.
