Conference paper (other academic/artistic)abstract
- Introduction: The objective of the present investigation was to compare two techniques for pediatric tonsil surgery with respect to postoperative pain and morbidity and changes in sleep behavior, health related quality of life (HRQL) and benefit due to surgery. Methods: 67 children (4,5-5,5 years) with tonsillar hypertrophy and obstructive sleep related distress with or without recurrent tonsillitis were randomized to either regular tonsillectomy (TE)(n=32) or intracapsular tonsillectomy/tonsillotomy (TT) (n=35) with Radiofrequency surgical technique (Ellman Int) Before TT/TE, the parents completed a validated Quality of Life survey of pediatric obstructive sleep apnea, the OSA18 (Obstructive Sleep Apnea-18) and a standardized assessment of their children-s behavior with the Child Behavior Checklist (CBCL). Six months after surgery, the parents repeated these measurements, and assessed the health related benefits of the surgery using the Glasgow Children´s Benefit Inventory (GCBI). Results: In the TT group, the children recorded less pain from the first day after surgery onwards, used fewer doses of painkillers and were pain-free 3 days earlier than the children in the TE group. Six months after surgery, there was no significant difference between TT and TE with regard to snoring and ENT-infections. The differences were all significant in the total scores and in all the individual domains between the initial OSA-18 and post-surgery scores (p<0.0001). The improvement in the total problem score measured with CBCL was also significant (p<0.01) and there were no differences between the TT and TE children. The improvements in all sub scores of the GCBI indicated a significant health benefit of both TT and TE. Conclusions: TT with RF-surgery is a safe method, which causes less pain and postoperative morbidity than regular TE and has a similar effect on snoring and recurrent infections. Young children with tonsillar hypertrophy and different degrees of obstructive sleep related distress all show an impact on HRQL and behavior. All improve dramatically after a tonsillar operation-improving just as much after TT as after TE. Based on these results, TT should be the first choice for treatment of these small children.

Tonsillotomi på förskolebarn-räcker det?

Conference paper (peer-reviewed)abstract
- Under förskoleålder sker en fysiologisk ökning av den sk Waldeyerska ringen med tillväxt av tonsiller och adenoid som del i utvecklingen av barnets immunförsvar Många barn kan under denna tid debutera med obstruktionsbesvär(snarkning och sömnapné). Traditionellt har tonsillerna och adenoiden genom tonsillektomi och abrasio helt avlägsnats för att komma till rätta med dessa symptom, kirurgi förenad med hög postoperativ smärtnivå. På senare tid har tonsillotomi, dvs partiellt borttagande av tonsillerna, återinförts som en något mer skonsam operationsmetod. Immunsystemetpåverkas möjligtvis inte heller i lika stor omfattning. Frågan är om detta ingrepp är tillfyllest på barn som är i den ålder då tonsillerna fortfarande växer? Syftet med föreliggande studie var att jämföra tonsillotomi med radiofrekvenskirurgi med fullständig tonsillektomi på förskolebarn vad beträffar postoperativ morbiditet och långtidseffekt på snarkning och infektionsnbenägenhet upp till två år efter operation med tonsillektomi. 67 förskolebarn(4-5 år)med symtomgivade tonsillhypertrofi randomiserades till reguljär tonsillektomi(TE) eller tonsillotomi(TT) med radiofrekvensteknik. I de flesta fall utfördes samtidigt abrasio. 6 månader efter operationen svarade alla på frågeformulär och 2 år efter operationen bedömdes de åter av ÖNH-läkare. Snarkningen före, direkt efter operationen och vid tiden för läkarbesöket utvärderades då med VAS TT barnen registrerade lägre smärta från första dagen efter operation och var helt smärtfria 3 dagar tidigare än TE-barnen. Sex månader efter operationen förelåg ingen skillnad på grupperna vad gäller snarkning och infektionsbenägehet. Efter två år hade två av de 34 TT-barnen och ett av de 33 TE-barnen blivit re-opererade pga recidiv av obstruktionsbesvär, TE-barnet med reabrasio. Övriga barn i båda grupperna var i stort sett besvärsfria vad gäller snarkning och ingen ökad infektionsbenägehet noterades hos något barn. VAS före/ två år efter operationen var 8,4/1,3 för TE och 8,5/1,6 för TT. Tre av TT barnen hade tonsillvävnad något utanför tonsillogen och hälften av TE barnen hade små tonsillrester i logerna. Cirka 6 % risk föreligger att ett yngre barn som opereras med tonsillotomi för obstruktionsbesvär behöver göra om operationen inom 2 år. Denna risk bör vägas mot den betydligt lägre postoperativa morbiditeten för tonsillotomi jämfört med tonsillektomi.

Journal article (peer-reviewed)abstract
- Objective: To evaluate outcome of two types of tonsil surgery (tonsillectomy [TE] + adenoidectomy or tonsillotomy [TT] + adenoidectomy) on vocal function perceptually and acoustically.Study Design: Sixty-seven children, aged 50–65 months, on waiting list for tonsil surgery were randomized to TE (n = 33) or TT (n = 34). Fifty-seven age- and gender-matched healthy preschool children were controls. Twenty-eight of them, aged 48–59 months, served as control group before surgery, and 29, aged 60–71 months, served as control group after surgery.Methods: Before surgery and 6 months postoperatively, the children were recorded producing three sustained vowels (/ɑ/, /u/, and /i/) and 14 words. The control groups were recorded only once. Three trained speech and language pathologists performed the perceptual analysis using visual analog scale for eight voice quality parameters. Acoustic analysis from sustained vowels included average fundamental frequency, jitter percent, shimmer percent, noise-to-harmonic ratio, and the center frequencies of formants 1–3.Results: Before surgery, the children were rated to have more hyponasality and compressed/throaty voice (P < 0.05) and lower mean pitch (P < 0.01) in comparison to the control group. They also had higher perturbation measures and lower frequencies of the second and third formants. After surgery, there were no differences perceptually. Perturbation measures decreased but were still higher compared with those of control group (P < 0.05). Differences in formant frequencies for /i/ and /u/ remained. No differences were found between the two surgical methods.Conclusion: Voice quality is affected perceptually and acoustically by adenotonsillar hypertrophy. After surgery, the voice is perceptually normalized but acoustic differences remain. Outcome was equal for both surgical methods.

Effects of tonsil surgery on speech and oral motor function
- 2008
-
In: The 12th Congress of the International Clinical Phonetics and Linguistics association. ; , s. 119-119
-
Conference paper (peer-reviewed)abstract
- Large tonsils decrease the upper airways and cause oral breathing in children. If oral breathing persists, it leads to muscular and postural alterations, which, in turn cause dentoskeletal changes. In Sweden 6% of all children, have tonsil surgery performed. The indications are usually recurrent tonsillitis or severe snoring and/or sleep apneoa. Oral motor dysfunction including swallowing problems , disordered speech and aberrant dentofacial growth are less recognized problems as indications for treatment. We report results from a project aiming at comparing oral motor function and speech in children trated with two different surgical methods, tonsillectomy (TE) and partial tonsil resection, tonsillotomy (TT). 67 children aged 4-5 years old on ordinary waiting list for tonsil surgery were randomized to either TE or TT. They were assessed with the Swedish version of Nordic Orofacial Test (NOT-S) and a Swedish phonological test. A voice recording was also made. The assessment was repeated 6 months after surgery. The results were compared to a control group without tonsil problems. No significant differences were found between the children operated with TE or TT. Both groups performed significantly better on the oral motor test at the postoperative assessment, and voice quality had improved. However, compared to the control group, the children with enlarged tonsils had a delay in phonological development, preoperatively that remained at the 6-month postoperative control

Journal article (peer-reviewed)abstract
- Tonsillar hypertrophy is common in young children and affects several aspects of the speech such as distortions of the dento-alveolar consonants. The study objective was to assess s-articulation, perceptually and acoustically in children with tonsillar hypertrophy and compare effects of two types of surgery, total tonsillectomy and tonsillotomy. Sixty-seven children, 50-65 months, on waiting list for surgery, were randomized to tonsillectomy or tonsillotomy. The speech material was collected pre-operatively and six months post-operatively. Two groups of age-matched children were controls. /S/-articulation was affected acoustically with lower spectral peak locations and perceptually with less distinct /s/-production before surgery, in comparison to controls. After surgery /s/-articulation was normalized perceptually, but acoustic differences remained. No significant differences between surgical methods were found.

Manual till LINUS 2.0 : LINköpingsUnderSökningen 2.0: Ett fonologiskt bedömningsmaterial för barn från 3 år
- 2019
-
Reports (other academic/artistic)abstract
- När ett barn med misstänkta tal- och språkavvikelser kommer till logoped för bedömning är det viktigt att samtliga aspekter av tal och språk beaktas. Under de år som svensk logopedi har vuxit fram, har ett flertal instrument för bedömning av barns tal- och språk tagits fram. Ett av dessa, Stora fonemtestet, som skapades i mitten av 1980-talet, har länge varit det enda vitt spridda testet av barns fonologi i landet. Testet fanns under flera år inte att beställa på förlag, vilket var ett av motiven till arbetet med att ta fram ett nytt fonologiskt bedömningsmaterial. Ett annat var att Enheten för logopedi vid Linköpings universitet sedan 2010 ingår i en större multicenterstudie med syftet att jämföra fonologiska avvikelser hos barn i olika länder. Inom ramen för detta projekt och genom några magisterarbeten i logopedi färdigställdes LINUS 2014. Som en direkt följd av det fortsatta internationella forskningssamarbetet och av feed-back från kollegor som använt materialet i sin kliniska vardag, kommer nu en ny version av materialet, LINUS 2.0. och finns för gratis nedladdning på http://phonodevelopment.sites.olt.ubc.ca/practice-units/swedish/. Vi hoppas att det även fortsatt skall komma till användning vid utredning av tal- och språkförmåga hos barn.Linköpings universitet, 2019Inger Lundeborg Hammarström

Oral Motor Function, Voice, Speech and Language in Children with Tonsillar Hypertrophy in Relation to Surgical Outcome
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- The aim of this thesis was two-fold: first, to evaluate four different functional aspects of the speech and language spectrum; oral-motor function, voice, /s/-articulation and phonology in preschool children with tonsillar hypertrophy before and after surgical treatment. The second aim was to investigate weather the outcome of surgery was equal for two surgical techniques; tonsillectomy or tonsillotomy combined with adenoidectomy when necessary. In all included publications (I-IV), 67 children on waiting list for tonsil surgery and randomized to either tonsillectomy (33) or tonsillotomy (34) participated. The children were assessed and audio-recorded within a month before surgery and six months postoperatively. Results were compared to age-matched control groups.In the first study, oral motor function was assessed using the Nordic Orofacial Test-Screening, NOT-S, consisting of a structured interview and a clinical examination. Before surgery, the children in the study group differed in all domains of the structured interview in comparison to age-matched controls and in the clinical examination regarding the parameters deviant lip position and trouble nose-breathing. Postoperatively oral motor functions were normalized in both surgical groups and no differences to age matched controls were observed. In study two, recordings of three sustained vowels (/α , u, i/) and 14 words elicited by picture naming were analysed both perceptually and acoustically. Compared to the controls, significant differences were found in the study group preoperatively with higher ratings on Visual Analogue Scales (VAS) for the voice quality parameters “hyponasality” and “compressed/throaty” and also lower for pitch. Significantly higher values on all studied perturbation measures (jitter, shimmer and Noise to Harmonics Ratio) were found. Regarding center frequencies of formants, the study groups had lower F3 values for /u / and also lower F2 and F3 for / i / compared to age-matched controls. After surgery there were no significant differences between the perceptual ratings of voice quality of the two surgical groups and there were no significant differences between the children in the surgical groups and the corresponding controls. The acoustic analyses showed a decrease in all the measures of perturbation for the study group after surgery with a slight difference between the two surgical groups. The children in the tonsillotomy group had higher shimmer value for /u/ and higher NHR for /α/. In comparison to the older controls significantly higher values were found an all perturbation measures and the difference seen regarding formant frequencies for the /i/-sound in comparison to controls still remained. The significantly lower third formant (F3) of the /u/-sound also remained. When comparing pre- versus postoperative results for the surgical group as a whole, a decrease was found on all perturbation measures postoperatively, however the differences were not statistically significant. A significant increase was found in formant 3 for /α/ and /u/ was found.The material used in the third study were speech samples containing the /s/-sound and elicited by picture naming and sentence repetition. Before surgery the study group was rated to have more indistinct /s/-sounds than agematched controls. The acoustic analyses showed that the study group had lower spectral peak values for the /s/-sound than controls. After surgery the operated children’s /s/-production did not differ perceptually from the older controls, neither as a whole group nor when divided according to surgical methods. Regarding the acoustic analyses however, the study groups differed from the age-matched control group showing that noise duration was longer and the peak location higher in the study groups.In study four, a Swedish phonology test was performed and transcribed phonetically. The transcription of each child was analyzed in terms of phonological processes and categorized into one of six developmental stages according to the model developed by Nettelbladt (1983) and adapted by Sahlén, Reuterskiold-Wagner, Nettelbladt & Radeborg (1999). A majority of the children in the study group (62.7 %) showed a slowed phonological development preoperatively (developmental stages 0-4), compared to the age-matched control group. Postoperatively the children in both surgical groups had improved their phonological skills. However, they were still behind in comparison to age-matched controls and the difference was even larger than before surgery.The results of this thesis project have clinical relevance for both speech and language pathologists (SLP’s) and ear-nose and throat-surgeons (ENT-surgeons). SLP’s must be aware of the potential impact of tonsillar hypertrophy on oral-motor function and the speech and language spectrum to be able to help affected children adequately and ENT- surgeons should include oral motor and speech and language problems as additional indications for tonsillar surgery.

Oral sensorimotor function in typically developing children 3 to 8 years old as assessed by the Nordic orofacial test, NOT-S
- 2014
-
In: Journal of medical speech-language pathology. - 1065-1438. ; 21:1, s. 51-59
-
Journal article (peer-reviewed)abstract
- Background: Oral senorimotor development is the basis for several vital functions for the child, hence orofacial dysfunction may be severely disabling. Recently, a comprehensive screening instrument assessing different aspects of orofacial function in adults and children age three and up was developed, the Nordic Orofacial Test-Screening (NOT-S). The aim of the present study was to establish developmental profiles of orofacial function for children 3 to 7:11 years old using NOT-S methods: A total of 231 typically developing children 3:0 to 7:11 years old were included. Data were compiled from previous investigations. Comparisons across ages and gender were made.Results: The total NOT-S score was below two for 58% (133) of all children in the study.There was a clear trend of lower total NOT-S score with increased age according to a best linear fit regression, R2= .81, p = .014. The number of children without any score on NOT-S increases dramatically for the seven-year-old children, 44% compared to 20% or lower for the other age groups. Boys had statistically significant higher scores than girls on the total NOT-S score and also for the clinical examination according to a Mann-Whitney U-test, p<.000 for both cases.

Scandcleft Project Trial 2—Comparison of Speech Outcome in 1- and 2-Stage Palatal Closure in 5-Year-Olds With UCLP
- 2020
-
In: Cleft Palate-Craniofacial Journal. - : SAGE Publications. - 1055-6656 .- 1545-1569. ; 57:4, s. 458-469

Journal article (peer-reviewed)abstract
- Objective: To investigate in-depth speech results in the Scandcleft Trial 2 with comparisons between surgical protocols and centers and with benchmarks from peers without cleft palate. Design: A prospective randomized clinical trial. Setting: Two Swedish and one Finnish Cleft Palate center. Participants: One hundred twelve participants were 5-years-old born with unilateral cleft lip and palate randomized to either lip repair and soft palate closure at 4 months and hard palate closure at 12 months or lip repair at 3 to 4 months (Arm A), or a closure of both the soft and hard palate at 12 months (Arm C). Main Outcome Measures: A composite measure dichotomized into velopharyngeal competency (VPC) or velopharyngeal incompetency (VPI), overall assessment of velopharyngeal function (VPC-Rate), percentage of consonants correct (PCC score), and consonant errors. In addition, number of speech therapy visits, average hearing thresholds, and secondary surgeries were documented to assess burden of treatment. Results: Across the trial, 53.5% demonstrated VPC and 46.5% VPI with no significant differences between arms or centers. In total, 27% reached age-appropriate PCC scores with no statistically significant difference between the arms. The Finnish center had significantly higher PCC scores, the Swedish centers had higher percentages of oral consonant errors. Number of speech therapy visits was significantly higher in the Finnish center. Conclusion: At age 5, poor speech outcomes with some differences between participating centers were seen but could not be attributed to surgical protocol. As one center had very few participants, the results from that center should be interpreted with caution. © 2019, American Cleft Palate-Craniofacial Association.
