ABSTRACT

A device for objective assessment of hypernasality index (percent rate of nasal acoustic energy to the whole energy produced during phonation or speech) of own construction is presented. The possibilities of clinical aplicability are discussed.

    ABSTRACT: The term insuffisance velopalatine was first used by Larmoyez in 1892 r. Nowadays the term is used to denote the failure of the palate to produce velopharyngeal closure that would completely block the nasopharynx from the lower pharynx during physiological processes of swallowing, blowing, speaking, breathing and ventilation of the internal auditory canal. Numerous surgical techniques used in the treatment of VPI were described in the past 100 years. Several techniques have been used to decrease the velopharyngeal space, like operations aiming at bulging of the posterior pharyngeal wall and alternating "Z-plasty" of the soft palate aiming at prolongation and improvement of the mobile function of the palate. The prospective studies were carried on from May 2003 to October 2004. Patients with severe forms of VPI were qualified for surgical treatment by a phoniatrist, speech therapist and plastic surgeon. All the surgical procedures were performed by the same surgeon. Bulging of the posterior pharyngeal wall by means of corionic graft was performed in 8 patients as the first stage treatment followed by prolongation of the palate by means of Furlow's technique 6 months later. The anatomical conditions as well as speech quality prior to, after the first and the second procedure were evaluated on the basis of direct examination, speech assessment, nasofibroscopic examinations and nasometric measurements. Examinations performed 6 months after termination of surgical treatment revealed improvement or significant improvement in speech quality, especially concerning reduced nasality, speech intelligibility and decreased nasal airflow (on an average from 48% to 33%). Five patients rated in questionnaires the outcome of treatment as "significant improvement". Complex staged management consisting in bulging of the posterior pharyngeal wall and Furlow's operation appeared to be a successful modality of treatment in patients with severe forms of velo-pharyngeal insufficiency in about 75% of cases.

    ABSTRACT: The aim of the study was the assessment of the late speech results the cleft palate patients. MATERIAL AND METHODIC. From January 1987 to December 1996 the first author performed 268 cleft palate surgeries. Of this number, 190 were complete unilateral and bilateral clefts, while 78 were operations of isolated soft palate. All the patients were consulted by a phoniatrist and a plastic surgeon. Among others, articulation, nasality, speech intelligibility were evaluated and nasometirc investigations were performed. The follow up examination involved 133 patients, 56 females and 77 males aged from 9 to 19 years (mean at the age of 13)--61 patients with unilateral cleft lip, alveolar process and palate (UCLP), 30 with bilateral clefts (BCLP) and 42 with isolated soft palate clefts (ICP). All the patients were operated on between 20 and 36 months of age (mean at 28 months). Two patients (1.5%) developed dehiscence of the wound on the palate and further two (1.5%) developed fistulae localized behind the alveolar process at a later time. All children with clefts were operated on by classical methods with the use of mucoperiosteal flaps for complete clefts according to Veauís method and soft palate clefts--Kilner-Wardill's method. Very good and good results of treatment were observed in 92% of cases. Poor outcome of treatment--excessive nasality or poor speech quality was observed in 11 patients (8%). A similar evaluation of the outcome of treatment was obtained on the basis of questionnaires sent to patients. It seems that good speech quality can be achieved despite relatively late palate repair using Veau and Kilner-Wardill methods.
