[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%.

[Postoperative complication in stapedectomy: excessive introduction of the prothesis in the oval window]. / Complicación postoperatoria en la estapedectomía: excesiva introducción de la prótesis en la ventana oval.

Postoperative failures and complications detected in patients who undergo surgery for otosclerotic disease are not uncommon in stapes surgery. Prosthesis displacement and incus necrosis are the most common findings in review stapedectomy. We report the case of a patient who had tinnitus, vertigo, and non-recovery of air conduction thresholds without neurosensorial lesions after stapes surgery. The suspected diagnosis of excessive introduction of the prosthesis in the oval window was confirmed by computed tomography, which showed the radio-opaque image of the McGee metal prosthesis. The prosthesis replacement and literature review are discussed.

[Subcutaneous cervical emphysema secondary to tooth extraction]. / Enfisema cervical subcutáneo secundario a extracción dental.

Cervical emphysema is rare and its diagnosis involves the ENT specialist. A case of cervical subcutaneous emphysema secondary to lower molar extraction is reported. The patient had no signs or symptoms other than cervical emphysema. Simple radiography and CT are recommended for early diagnosis. The etiopathogenic mechanisms of subcutaneous cervical emphysema are reviewed. Recent literature contains few cases of dental origin.

[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.
