RESUMEN
BACKGROUND: The purpose of this study was to evaluate the efficacy of cloth stoma covers (bibs) to compensate for breathing unconditioned air after laryngectomy and loss of heat-moisture-exchange (HME) functions of the upper airways, which, to the best of our knowledge, has never been reported. In addition, we compared the efficacy of inexpensive, simple, locally made, noncommercial fabric bibs with commercial bibs and stick-over-the-stoma HME devices and to determine whether wetting the bib improves the tracheal climate. METHODS: Tracheal temperature and humidity were studied in 25 patients who underwent a laryngectomy with a purpose-built sampling device. RESULTS: Noncommercial and commercial bibs effectively heat and humidify inspired air (p < .05). Both bibs compare favorably with commercial HME devices. There is no benefit in using a commercially produced Buchanan Bib over an inexpensive noncommercial bib. Wetting a bib proved to be counterproductive. CONCLUSION: Inexpensive, noncommercial bibs are effective and improve tracheal climate and benefit patients with laryngectomies. © 2015 Wiley Periodicals, Inc. Head Neck 38: E480-E487, 2016.

We report three cases of hydatid disease of the skull base and the treatment thereof. The first involved the anterior cranial fossa and paranasal sinuses. The second was located in the infratemporal fossa. The last involved the temporal bone and posterior cranial fossa. Hydatid disease is endemic in many parts of the world where livestock farming is practiced and is highly endemic in sub-Saharan Africa. Although hydatid disease of the head and neck is rare, it should be considered in the differential diagnosis of cystic disease in the head and neck region. Of the three forms of hydatid disease, Echinococcus granulosis is most common and gives rise to cystic hydatid disease. Most hydatid cysts are "silent," but become clinically apparent because of their mass effects, when they rupture, or if they become superinfected. Computed tomography scanning and magnetic resonance imaging are the best diagnostic tools. Hydatid disease can be successfully treated by a combination of surgery and chemotherapy.
