Isolated vagus nerve paralysis associated with internal carotid artery dissection.

Dysphagia and hoarseness caused by laryngopharyngeal paralysis associated with internal carotid artery (ICA) dissection is rare. We reported a case which recovered spontaneously. A 57-year old man visited our hospital complaining of dysphagia and hoarseness lasting for two weeks.

Resolution of vocal fold polyps with conservative treatment.

Objectives: Vocal fold polyp is generally thought to require surgical removal. However, a certain proportion of polyps resolve with conservative treatment. This study was performed to clarify the frequency of spontaneous resolution of vocal fold polyp and identify features associated with polyps that are likely to resolve without surgery.

[Use of the buccal fat pad for vocal fold injection].

In recent years, autologous fat has been increasingly used for intracordal injection as a means of vocal rehabilitation in patients with deficient glottal closure, and the dipose tissue used has for the most part been harvested from the lower abdomen. However, patients differ considerably in the amount of fat available in the lower abdomen, and obtaining sufficient fat is often difficult in patents with a low body mass index (BMI). To overcome this problem we tried adopting a method that uses the buccal fat pad, as practiced in plastic surgery.

Laryngeal carcinoma presenting as a large anterior neck abscess.

Laryngeal carcinoma presenting as a cervical abscess is rare, so that its diagnosis is not easy. We described a case of laryngeal squamous cell carcinoma presenting as a prelaryngeal large abscess. Markedly swollen false vocal fold inhibited fiberscopic examination of the vocal folds.

Cervical emphysema secondary to pneumomediastinum as a complication of childbirth.

Pneumomediastinum and cervical emphysema usually occur following esophageal or chest trauma. Rarely do they occur as a complication of childbirth, and only approximately 200 such cases have been reported in the literature worldwide. We describe a new case, and we review the clinical picture, pathophysiology, and management of these conditions.
