Due to the mental and physical impairments in family and neonates born with cleft lip and palate, basic understandings of pre, intra and post- operative measures in such patients are considered to be highly crucial. In post- operative period, patients as well as their relatives, need to be informed about the scope and the different dimentions of the problem. A thorough evaluation within a specialised team is necessary. The specialised team is consisted of speech pathologist, reconstructive surgeon, dentist, craniofacial surgeon, pediatrist, and etc. In addition, basic health check and speech rehabilitation must be conducted, as soon as possible. Furthermore, velopharyngeal movements, tonsils, uvula, palatopharyngeal walls with relation to the nasopharynx area also need to be assessed. A precise therapeutic program is essential in this matter. Evaluation of both clinical and paraclinical as well as speech therapy within six weeks, six month and twelve months post- surgery is needed. Any success or failure should be identified and discussed within the specilised team for further different speech therapy actions. Either prosthesis or re- operation might be recommended if the team reaches to an agreement after the proper assessment.

Objective: Research is designed to determine speech respiratory measures in spastic cerebral palsied children versus normal ones, to be used as an applicable tool in speech therapy plans. 

Materials & Methods: Via a comparative cross-sectional study (case–control), and through a directive goal oriented sampling in case and convenience approach for controls twenty spastic cerebral palsied and twenty control ones with age (5-12 years old) and sex (F=20, M=20) were matched and identified. All possible inclusion and exclusion criteria were considered by thorough past medical, clinical and para clinical such as chest X-ray and Complete Blood Counts reviews to rule out any possible pulmonary and/or systemic disorders. Their speech respiratory indices were determined by Respirometer (ST 1-dysphonia), made and normalized by Glasgow University. Obtained data were analyzed by independent T test.

Results: There were significant differences between cases and control groups for "mean tidal volume", "phonatory volume" and "vital capacity" at a=0/05 values and these values in patients were less (34%) than normal children (P<0/001).

Conclusion: Measures obtained are highly crucial for speech therapist in any speech therapy primary rehabilitative plans for spactic cerebral palsied children.

Objective: The respiration role is not limited to vital function but it also important in speech process. The present research is aimed to measure different parameters of speech breathing values in patients suffering Mustard Gas injuries versus normal individual.

Materials & Methods: Research was applied as case-control, cross – sectional and analytical method. The sampling pattern was convenience. Among patients, 19 were selected within injured patients from Baghiatallah hospital and 20 from those of normal individuals from welfare and rehabilitation sciences university stuffs. Normal people were matched based on their age, gender and other criterias within 30-50 years of age. ST1 Dysphonia manufactured by G.M. Instruments Ltd.) was used to measure parameters of speech breathing, that include “Vital capacity”, “Phonation time”,” Phonation volume”,” Mean flow rate”,” Total expired volume”. And also,” Vocal velocity index” and “Phonation Quotient” were calculated. The independent T-test was used for data analysis. 

Results: Research findings shown statistically significant difference between two groups in Vital capacity (P<0/001), Phonation time (P<0/001), Phonation volume (P<0/001), Vocal velocity index (P=0/004), Total expired volume (P<0/001) and Phonation Quotient (P=0/046), but there was no significant difference in Mean flow rate between case and control group (P=0/615). 

Conclusion: present research has indicated, chemical war substance, not only has rendering effects upon vital respiration, but also has alternate patient’s speech breathing capabilities greatly. Such finding can be measured and evaluated the disturbed phonatory criteria in such patients and be a valued guide for speech & language phatologists, during treating such patients.
