Abstract [sv]

Läpp-, käk och gomspalt (LKG) kan medföra svårigheter med tal, artikulation och röst. Enligt tidigare forskning har vuxna individer behandlade för LKG liknande förekomst av röstavvikelser som kontrollpersoner utan spalt. Syftet med denna studie var att undersöka grad av röstavvikelser hos vuxna patienter behandlade för enkelsidig LKG och kartlägga eventuella samband mellan röstavvikelser och kirurgiska metoder för gomslutning, kön och operation med eller utan svalglambå samt jämföra röstresultat med data från individer utan LKG. Sjuttio patienter behandlade för enkelsidig genomgående LKG deltog i studien, varav 45 patienter hade opererats med gomslutning i en seans och 25 patienter hade opererats i två seanser. Elva av patienterna i patientgruppen hade genomgått svalglambåoperation. I studien ingick även en åldersmatchad kontrollgrupp med 63 individer utan LKG. Röstinspelningar utvärderades med perceptuell röstbedömning med Stockholm Voice Evaluation Approach (SVEA) av två erfarna logopeder. Skattning skedde individuellt av randomiserade och blindade inspelningar. Inter- och intrabedömarreliabilitet beräknades. Grad av avvikelse i röstkvalité var ca. 5/100 i patientgrupp och kontrollgrupp vilket är lägre jämfört med tidigare studier. “Knarr” fanns lägre i patientgruppen i jämförelse med kontrollgrupp. Skattningar av övriga röstparametrar skiljde sig inte mellan patientgrupp och kontrollgrupp. Patienter opererade med gomslutning i en eller två seanser hade inga skillnader i röstparametrar. Enstaka små skillnader fanns mellan könen. Ingen skillnad fanns mellan patienter som genomgått svalglambåoperation och de som inte gjort det.

Abstract [en]

Cleft lip and palate (CLP) may cause impairments in speech, articulation and voice. Treatment of patients with CLP include different types of palatoplasty. Recent studies have found a comparable prevalence rate of dysphonia in adult patients treated for CLP and controls without cleft. The purpose of this study was to investigate the rate of dysphonic deviation in adult patients treated for unilateral CLP and determine, if any, the relationship between voice quality outcome and differences in surgical procedures, gender, palatoplasty with or without pharyngeal flap surgery and compare the voice characteristics with age related normative data. Seventy patients treated for unilateral CLP with one- or two-stage palatoplasty participated in this study, of which 45 patientshad undergone one-stage palatoplasty and 25 patients two-stage palatoplasty. Eleven ofthe patients had also undergone pharyngeal flap surgery. Data from an age matched non-cleft group consisted of 63 participants. Sound recordings of participants' voices were perceptually assessed by two speech-language pathologists. Individual ratings of randomized and blinded sound recordings were performed. Inter- and intra-raterreliability was calculated. The study showed a lower degree of dysphonia in patients treated for unilateral CLP than earlier studies. Among patients treated for unilateral CLP and the non-cleft group, a degree of approximately 5/100 voice quality deviation was found. ”Vocal fry” was found significantly lower in patients treated for CLP than the non-cleft group. Measures of voice parameters did not differ significantly between patients and non-cleft groups. Patients that had undergone palatoplasty in one or two stages showed no significant differences in voice parameters. Minor statistical significance was found in a few of the measured voice parameters as related to gender. Between patients that had undergone pharyngeal flap surgery and those that had not no differences were found.
