  • Background and Objectives : Esophageal voice, Silicone voice Prosthesis with tracheo-esophageal (T-E) puncture have been used as vocal rehabilitation methods for postlaryngectomy. However, long-term follow-up in the voice rehabilitation in the total laryngectomees has not been reported. The purpose of this study is to analyze practice of postlaryngectomy voice rehabilitation and to find the effective voice rehabilitation. Materials and Methods : From Jan 1992 until June 2002, 75 patients underwent a total laryngectomy at Yongdong Severance Hospital. We retrospectively studied voice rehabilitation methods commonly used, acquisition levels of esophageal speech, patients satisfaction scale (5 rating scale) according to the methods in 33 of them (40 died, 2 unavailable) by using charts review, telephone interview. Results : T-E speech is most commonly used by 14 patients (42.4%) : A tracheo-esophageal procedure (primary or secondary puncture) by 21 : and 8 patients removed Provox. 1 patient had no voice rehabilitation. 7 patients (21.2%) have used esophageal speech : 4 patients of them have used it after removing Provox. Electrolarynx has been used with other voice rehabilitation methods : 4 patients have only used this method and 3 patients with T-E speech, 1 patient with esophageal speech. However, 6 patients (18%) remained without a substitute voice rehabilitation. In the satisfaction with speech and management of voice rehabilitation methods, patients using esophageal speech were most satisfied (4.1), patients with T-E speech were unsatisfied (2.3). Regarding with the acquisition level of esophageal speech in 33 patients, 22 patients (66.6%) failed without functional speech. Conclusion : To increase patients satisfaction and to achieve successful voice rehabilitation after total laryngectomy, preoperative counseling, pretesting, appropriate patient selection of each method and team decision-making and postoperative voice therapy must be considered.

  • Cerebral palsy is one of the most serious forms of disorders of the psychophysical development of children, which manifests itself in disturbances of motor functions, which are often combined with speech disorders, other complications of the formation of higher mental functions, and often with a decrease in intelligence. The article will discuss the speech disorder in children with cerebral palsy. Emphasis is placed on some important aspects, which should bear in mind, investigating the problem of specifics of speech development of children with cerebral palsy. In particular at the heart of speech disorders in the cerebral palsy is not only damage to certain structures of the brain, but also the later formation or underdevelopment of those parts of the cerebral cortex, which are of major importance in linguistic and mental activity. This is an ontogenetically young region of the cerebral cortex, which is most rapidly developing after birth (premotor, frontal, temmono-temporal). It is important to take into account, that children with cerebral palsy have disturbances of phonemic perception. Often, children do not distinguish between hearing sounds, cannot repeat component rows, allocate sounds in words. At dysarthria, there are violations of pronunciation of vowel and consonant sounds, tempo of speech, modulation of voice, breathing, phonation, as well as asynchronous breathing, alignment and articulation. As a result, we identified the main features and specifics of the speech development of children with cerebral palsy and described the conditions necessary for the full development of language. Language disturbances in children's cerebral palsy depend on the localization and severity of brain damage. Great importance in the mechanism of speech disorders has a pathology that limits the ability of movement and knowledge of the world.

  • Background and Objectives We aimed to develop a Korean version of the velopharyngeal insufficiency (VPI) speech corpus system. Subjects and Method After developing a 3-channel simultaneous speech recording device capable of recording nasal/oral and normal compound speech separately, voice data were collected from VPI patients aged more than 10 years with/without the history of operation or prior speech therapy. This was compared to a control group for which VPI was simulated by using a french-3 nelaton tube inserted via both nostril through nasopharynx and pulling the soft palate anteriorly in varying degrees. The study consisted of three transcriptors: a speech therapist transcribed the voice file into text, a second transcriptor graded speech intelligibility and severity and the third tagged the types and onset times of misarticulation. The database were composed of three main tables regarding (1) speaker's demographics, (2) condition of the recording system and (3) transcripts. All of these were interfaced with the Praat voice analysis program, which enables the user to extract exact transcribed phrases for analysis. Results In the simulated VPI group, the higher the severity of VPI, the higher the nasalance score was obtained. In addition, we could verify the vocal energy that characterizes hypernasality and compensation in nasal/oral and compound sounds spoken by VPI patients as opposed to that characgerizes the normal control group. Conclusion With the Korean version of VPI speech corpus system, patients' common difficulties and speech tendencies in articulation can be objectively evaluated. Comparing these data with those of the normal voice, mispronunciation and dysarticulation of patients with VPI can be corrected.

  • Background: The submucous cleft palate (SMCP) is a type of cleft palate that may result in velopharyngeal insufficiency (VPI). Palate muscles completely separate oral and nasal cavities by closing off the velopharynx during functional processes such as speech or swallow. Also, hypernasality may arise from anatomical or neurological abnormalities in these functions. Treatments of this issue involve a combination of surgical intervention, speech aid, and speech therapy. This case report demonstrates successfully treated VPI resulted from SMCP without any surgical intervention but solely with speech aid appliance and speech therapy. Case presentation: A 13-year-old female patient with a speech disorder from velopharyngeal insufficiency that was caused by a submucous cleft palate visited to our OMFS clinic. In the intraoral examination, the patient had a short soft palate and bifid uvula. And the muscles in the palate did not contract properly during oral speech. She had no surgical history such as primary palatoplasty or pharyngoplasty except for tonsillectomy. And there were no other medical histories. Objective speech assessment using nasometer was performed. We diagnosed that the patient had a SMCP. The patient has shown a decrease in speech intelligibility, which resulted from hypernasality. We decided to treat the patient with speech aid (palatal lift) along with speech therapy. During the 7-month treatment, hypernasality measured by a nasometer decreased and speech intelligibility became normal. Conclusions: Surgery remains the first treatment option for patients with velopharyngeal insufficiencies from submucous cleft palates. However, there were few reports about objective speech evaluation pre- or post-operation. Moreover, there has been no report of non-surgical treatment in the recent studies. From this perspective, this report of objective improvement of speech intelligibility of VPI patient with SMCP by non-surgical treatment has a significant meaning. Speech aid can be considered as one of treatment options for management of SMCP.

  • Total laryngectomy remains as an important treatment option in selected patients with laryngopharyngeal cancers, which inevitably sacrifices naturally produced voice. Much effort has been devoted to voice restoration for these laryngectomized patients. Several ways of voice rehabilitation after total laryngectomy have been developed and utilized thus far, including tracheoesophageal shunt speech, esophageal speech, pneumatic speech aid, and electrolarynx. Of these, tracheoesophageal shunt speech appears to be the most effective voice restoration method, while other trials might also be useful in special situations. Nevertheless, each method has its own unique mechanisms of voice production, thus has its advantages and drawbacks in clinical setting. In this review, we discuss the currently available management options for the rehabilitation of laryngectomized voice.
