Description
Technical Field
The invention relates to an aerodynamic device, in particular to an aerodynamic device suitable for analyzing causes of parapalatopharyngeal dysfunction, and belongs to the technical field of aerodynamic devices.
Background
Speech language rehabilitation is one of the core contents of the whole rehabilitation of cleft palate patients, speech language pathology specialties are established only in 2015 in China, about 2 thousands of people are optimistically estimated by national practitioners, the number of the people is extremely mismatched with the total number of the population in China, and the distance between the number of the people and 20 thousands of the people in the United states is also a huge distance. Cleft palate speech therapy is used as 'cleft palate speech language rehabilitation of the most mysterious part in communication disorder', and in the current development stage, cleft palate speech therapy not only has the technical introduction problem, but also relates to the difference of the Chinese and English systems. Therefore, the development of clinical scientific research activities of any Mandarin Chinese cleft palate speech language pathology can fill in international and domestic blank researches.
Cleft lip and palate is a common congenital malformation, the global average incidence rate is 0.17%, and China is a high-incidence country of cleft lip and palate, and the incidence rate is 0.182%. Cleft lip and palate or cleft palate alone can negatively impact effective communication among patients, thereby causing significant social, emotional, and educational problems.
Rehabilitation of speech function in patients with cleft palate is a complex multifactorial problem based on knowledge of the fundamental laws of speech language development and knowledge of anatomical abnormalities in cleft palate. Palatopharyngeal function and verbal language development are key contributing factors in achieving "normal speech language and communication".
1. Limitations of current clinical assessment of palatopharyngeal closure function in treatment decisions
Palatopharyngeal closure is a spontaneous, central nervous system regulated movement that is achieved by gradually coordinating muscle movements during early learning of speech by individuals. Palatopharyngeal dysfunction can be divided into three major categories: structural abnormalities, neurogenic/myogenic abnormalities, and functional coordination abnormalities. Common malatopharyngeal insufficiency is usually caused by abnormalities in the palatal anatomy. The evaluation of palatopharyngeal function is used to determine whether the palatopharyngeal function is disordered and the palatopharyngeal function is not completely closed due to anatomical or physiological defects, or the individual lacks good muscular coordination and adaptability. However, the types are not completely independent, and the main cause of dysfunction is only one, but the patient may have two or three factors which act simultaneously. Patients after cleft palate present with hypopituitarism, although with definite structural deficits and history of treatment, these three factors are also differentiated, especially if there is a dysfunction in functional coordination. However, the current clinical examination means cannot make such distinction, which brings great challenges to treatment decision.
in a classical mode of evaluating the palatopharyngeal closing function after clinical cleft palate operation, a nasopharynx fiberscope can directly view a palatopharyngeal closing area, and particularly can provide anatomical physiological information for the formulation of an operation scheme, such as the severity degree, the closing form, the position of incomplete closing, the motion conditions of the pharyngeal side and the back wall, the symmetry degree of a soft palate in voice, and the motion capability including the speed and the duration in motion.
Especially when the closure rate is judged to be 0.8-0.9, the diagnostic decision is increasingly difficult, is it speech or surgery first, or is it waiting for observation? Under ideal procedures, diagnostic treatment is needed to distinguish whether there is a problem with the ability of the muscles to coordinate and adapt, and then make treatment decisions. However, on one hand, the method is a resource-consuming process, needs to invest in language therapy resources and is very dependent on the experience and the therapy level of a speech language therapist; on the other hand, in cross-discipline team collaboration, surgeons encounter decisions that are considered highly subjective because of the lack of objective evidence.
2. General description of other techniques
summary of the testing technique of nasal sound meter
The nasal sound meter is a computer-aided device invented by Kay electromrics (Pinebrook, New Jersey), and mainly measures the relative ratio of the nasal cavity sound wave intensity and the oral cavity sound wave intensity of a subject during continuous pronunciation (Dalston et al 1981). The device places a sound blocker on the patient's upper lip. Microphones are arranged on two sides of the barrier device to collect the sound wave intensity of the oral cavity and the nasal cavity when a patient pronounces, and collected sound can be filtered and digitalized by the individualized electronic module. Kayeeletrics software (version 1.7) processes the information and gives a "nasal resonance score" (nasalance score) which is the ratio of the intensity of the sound waves in the nasal and oral cavities multiplied by 100. In making the nasal flow assessment, the calculated nasal and oral sound wave intensities are the average intensities of the patient's vowels and consonants when pronouncing the test sentence. The standardized pronunciation material for scoring has a time period of about 100 seconds, and the device is improved based on the Tonar II device invented in Fletcher1976 (Fletcher and Bishop 1970). If the nasal resonance score is too high when the consonant without nasal cavity pronunciation is given out, the palate pharynx insufficiency and the nasal sound overweight are often prompted; conversely, if the nasal resonance score is too low during the onset of nasal consonants, a low nasal tone and/or nasal airway abnormality is indicated (Dalston et al 1981). Dalston et al (1981) after studying the sensitivity and specificity of nasal phonometers suggested that this device is a very good tool for validating a diagnosis if the examiner considers that the patient's nasal sounds are too heavy. Sensitivity and specificity studies of the nasal tonometer for patients without concomitant palatopharyngeal dysfunction confirm that its diagnostic ability for nasal tip is also within the clinician's expectations, but if patients have both nasal tip and nasal airway patency exacerbations, the diagnostic ability of the nasal tonometer for nasal tip is diminished. Therefore, the device may have poor diagnosis capability for patients with palatopharyngeal insufficiency accompanied by nasal airway abnormality (Dalston et al 1981), and the clinical application of the rhinophonometer cannot replace the doctor's hearing judgment on the excessive and weak nasal sounds, but the device can provide baseline data for the identification of palatopharyngeal insufficiency, the evaluation of treatment efficacy, the evaluation of palatal prosthesis adaptability and the visual biofeedback of voice treatment to promote the smooth progress of clinical process.
The nasal sound meter must be calibrated in use strictly according to the manufacturer's instructions. The head cap is then adjusted according to the patient's condition, and the patient reads a piece of standardized pronunciation material as requested by the doctor. This procedure is generally applicable to children patients 3 and over 3 years of age, and if the patient is below this age, the concentration is relatively weak and the pronunciation and language abilities are not well developed. After the patient's voice is entered into the computer, the starting and ending positions are marked by a cursor. Then the software 'calculating' function is started, and the average value and the standard deviation of the nasal resonance score are automatically calculated.
② Warren and DuBois detection technology (Warren and DuBois1964)
It is often clinically necessary to detect differences in nasal airflow and air pressure above and below the palatopharyngeal closure, from which the size of the palatopharyngeal opening and the resistance to airflow at that location can be assessed during a plosive attack. The detection of the gas pressure-flow can provide the information related to the mouth and the nasal cavity during pronunciation and the resistance condition of the system at the same time. However, this detection does not describe the movement of a particular structure, such as the palatine sail and lateral pharyngeal wall, or the location and structure of the associated opening.
③ PERCI technique
Warren (1979) invented an electronic scoring device for instantaneous Palatal Efficiency (PERCI), which is mainly used for assessing the function of the palatopharyngeal function during pronunciation, and the PERCI is capable of recording and assessing the difference in air pressure in the oral cavity and the nasal cavity. By studying 75 patients with cleft palate, Warren considered the pressure difference if the patients PERCI detected>3.0, the palatopharyngeal orifice has an area of generally 10mm2Or less; if PERCI reads<1.0, the palatopharyngeal orifice area is usually greater than 20mm2. Patients with PERCI readings between 1 and 2.9 are generally considered to have palatopharyngeal aperture areas between 10 and 20mm2In the meantime.
Fletcher and Bishop (1970) improve The method for detecting The sound intensity of The Oral cavity and The Nasal cavity of a patient with excessive Nasal sound, and invent an Oral-Nasal cavity sound intensity Ratio detection device (TONAR) which records The voltage number of Oral-Nasal cavity sound signals and depicts The Ratio of The voltage number of The Oral cavity sound signals to The voltage number of The Nasal cavity sound signals.
3. Disadvantages of the present general technical profiles and the present and disadvantages of use
Nasal tonometers require a natural norm and do not provide much information in subdividing the causes of palatopharyngeal closure dysfunction.
The two aerodynamic techniques are only limited to university laboratories, and have not yet been clinically popularized and used; on the other hand, the guiding significance for clinical treatment is not large, and in addition, the device is too complex and is not suitable for clinical use.
