[Cervical cysts of second branchial arch. Retrospective study of 14 cases].

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%.

[Bilateral recurrent nerve paralysis secondary to Ludwig's angina].

Although the incidence of Ludwig's angina has diminished, it still occurs. This disease can have life-threatening complications, including deep neck infection and mediastinitis. We report a case of Ludwig's angina with bilateral vocal cord paralysis secondary to cervical spread of infection.

[Postoperative complication in stapedectomy: excessive introduction of the prothesis in the oval window].

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.

[Nasal septum cyst of odontogenic origin].

Cysts in the nasal septum are unusual, and the presence of a dental cyst is even rarer. A cyst of dental origin was produced by dental root fracture in the nasal septum. The differential diagnosis and management are discussed.

[Retroauricular approach to complete obliteration of the external ear canal caused by osteoid osteoma].

Osteoid osteoma of the temporal bone is an infrequent benign bone tumor. The suspected diagnosis is based on clinical findings (occasionally pain, cosmetic deformities, repeated external otitis and conductive hearing loss), otoscopy, the radionuclide bone scan, and computerized tomography. Histopathology confirms the diagnosis of osteoma. Pain responds to acetylsalicyclic acid. Treatment is surgical excision by curettage and eburnation of the bone margins using an endaurul approach. We report a complete obliteration of the outer ear canal by an osteoid osteoma in a 32-year-old patient. A postauricular approach was required because of the large size of the tumor.

[Subcutaneous cervical emphysema secondary to tooth extraction].

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.
