Laryngopharyngeal sensory deficits and impaired pharyngeal motor function predict aspiration in patients irradiated for nasopharyngeal carcinoma.

Objectives/hypothesis: To assess the contribution of laryngopharyngeal sensory deficits and impaired pharyngeal motor function to aspiration in patients irradiated for nasopharyngeal carcinoma.

Study Design: A retrospective study at a tertiary referral university teaching hospital.

Methods: One hundred consecutive patients who underwent radiotherapy for nasopharyngeal carcinoma referred to a dysphagia clinic underwent sensory testing of their laryngopharynx and endoscopic evaluation of their swallowing.

Age and outcome of cochlear implantation for patients with bilateral congenital deafness in a Cantonese-speaking population.

Objective: To evaluate the effect of age at implantation by assessment of speech perception in cochlear implant users with bilateral congenital deafness.

Design: A retrospective cohort analysis of 60 cochlear implant users (age at implantation, 1.01 to 22.

Early swallowing problems in a cohort of patients with nasopharyngeal carcinoma: Symptomatology and videofluoroscopic findings.

Objective: To study the incidence and the degree of swallowing dysfunction in patients with nasopharyngeal carcinoma (NPC) who underwent radiation therapy treatment.

Institution: The study was conducted in the Prince of Wales Hospital, a tertiary teaching hospital of the Chinese University of Hong Kong.

Materials And Methods: From October 1999 to July 2001, a cohort of 20 consecutive patients with newly diagnosed NPC was prospectively studied.

Cantonese tone perception ability of cochlear implant children in comparison with normal-hearing children.

Background And Objective: Cantonese is a tone language. A change in the fundamental frequency pattern within the same phonemic segment causes a change in the lexical meaning. The present study examined the Cantonese tone perception ability of cochlear implant children in comparison with normal-hearing children.
