RESUMO
Evaluation of Physiologic Frequency Range (PFR) and Musical Frequency Range (MRP) of Phonation was performed on 56 adults (singers and nonsingers) presenting with superior laryngeal nerve (SLN) paresis or paralysis confirmed by laryngeal electromyography. The most common etiology was neuritis (69.7%), followed by iatrogenic and unknown causes,each accounting for 10.2% of cases, and finally trauma (8.9%). Both female and male singers with SLN paresis or paralysis had significantly higher PFR and MPR than nonsingers. Female classical singers presented PFR and MPR of up to 10 semitones (ST) higher than nonclassical singers and nonsingers. The lowest PFR and musical ranges were found in patients with SLN paresis associated with recurrent laryngeal nerve paresis or paralysis. The authors suggest that voice range measurement is a useful parameter for analyzing the effects of SLN paresis or paralysis on voice and that it may also assist in measuring outcome following voice therapy.

Cornelia de Lange syndrome (CDLS) is characterized by multiple congenital malformations and mental retardation. New studies have documented otolaryngologic abnormalities. We examined 45 patients with CDLS. Virtually all had hearing loss, and most had impaired language development. Other otolaryngologic abnormalities, including external auditory canal stenosis and cleft palate, were also common. Because of the high incidence of otolaryngologic abnormalities, and the need for early intervention, it is important for otolaryngologists to recognize CDLS manifestations in the head and neck.
