The aim of the present study was to establish whether the early signs of various orofacial dysfunctions, malocclusions, or occlusal interferences can predict the development of temporomandibular dysfunction (TMD) in young adults. Forty-eight subjects referred for speech therapy and 49 controls participated in all four stages of this longitudinal study. The subjects were examined at the ages of 7, 10, 15, and 19 years. The phoniatrician diagnosed errors in place of articulation and problems in the movement and co-ordination of the speech articulators. Occlusion, TMD signs (palpatory tenderness of the masticatory muscles, and of temporomandibular joints (TMJ), jaw deviation on opening, and clicking), mandibular movement capacity and occlusal interferences were registered by the orthodontist. Multiple logistic regression models were applied in order to evaluate whether single signs of TMD at the age of 19 years were related to previous/present malocclusions or interferences, to misarticulations of speech, problems in oral motor skills, or other signs of TMD. The effect of gender was also considered. The results showed that excessive overjet was the only variable which seemed to consistently increase the risk of TMD. In addition, girls seemed to be more prone to the development of TMD than boys. Although, during growth, there were both local and central factors associated occasionally with TMD development, the predictive value of those variables in the estimation of the individual risk of TMD was rather small.

Background The aim of this study was to determine the incidence, risk factors, and spontaneous recovery rate of vocal fold paresis (VFP) with routine laryngoscopy before and after thyroid surgery. Methods All consecutive patients undergoing primary or redo thyroid surgery between years 2011-2016 were prospectively registered in an electronic database, and scheduled for pre-and postoperative laryngoscopic vocal fold inspection by otolaryngologists independently of the surgical team. Results A total of 920 thyroid operations with 1296 nerves at risk were performed in 866 patients. Pre-and postoperative laryngoscopy was done in 95% and 98%, respectively. Preoperative VFP was detected in 24 (2.8%) patients. New postoperative VFP was found in 53 of 920 operations (5.8%) and in 55 of 1296 nerves at risk (4.2%). After 12 months, 14 had recovered full vocal fold function and eight had near-complete recovery. VFP was permanent after 29 operations (3.2%); two patients were lost to follow-up with uncertain outcome. Of the 1296 nerves at risk, injury was permanent in 30 (2.3%). In multivariate analysis, patients operated for recurrent goiter had nearly nine times higher risk of new VFP (23% rate), whereas patients with malignant histology had three times higher risk of postoperative VFP (up to 22% rate). Conclusion VFP continues to be a serious complication of thyroid surgery, especially in operations for redo goiter and thyroid malignancy. The incidence of VFP may be underestimated unless laryngoscopic examinations are performed routinely.

Associations between different types of misarticulations and morphology as well as function of the speech articulators were assessed in 287 first-grade children. Sounds produced too far anteriorly evidently were due to immaturity of the articulatory speech movements, which showed a tendency to improve spontaneously with age. Sounds produced too far posteriorly correlated positively with problems in coordinating the movements of different muscles of the tongue, indicating a possible dyspractic origin. Children who had problems with lip tonus were prone to have laterally produced misarticulations.
