ABSTRACT

OBJECTIVE: This study aimed to evaluate the long-term stability of surgical maxillary expansion using patient-specific fixation implants (PSFIs) without intraoral retention. MATERIALS AND METHODS: Fifteen patients who had undergone segmented Le Fort I osteotomy and PSFIs with available preoperative (t0) early (t1) and 1-year follow-up computed tomography (CT) scans (t2) were evaluated. The early and 1-year 3D models were superimposed to transfer the bony landmarks; the distances between each pair of landmarks at the different time points were then measured. The distances between the canines and second molars were also measured directly on the CT scans. RESULTS: The achieved maxillary expansions ranged from a median of 4.39 (2.00-6.27) mm at the greater palatine foramina to a median of 2.14 (1.56-2 > 83) mm at the canine level of the palatal bone. One year postoperatively, the changes in skeletal diameters ranged from a median of - 0.53 (- 1.65 to 0.41) mm at the greater palatine foramina (p = 0.12) to 0.17 (- 0.09 to 0.32) mm at the canine level of the palatal bone (p = 0.56). Changes in dental arch diameters ranged from a median of - 0.6 (- 2 to 0.00) mm between the second molars to - 1.3 (- 1.8 to - 0.25) mm between the canines (P < 0.05). CONCLUSION: This study showed the stability of maxillary expansion osteotomy using PSFIs, even without postoperative intraoral retention. CLINICAL RELEVANCE: PSFIs are a reliable method for the surgical treatment of transverse maxillary discrepancy. PFSIs are easy-to-use and improve surgical accuracy.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the recurrence rate of lithiasis following minimally invasive surgery to identify risk factors and mechanisms for recurrence of salivary gland lithiasis. STUDY DESIGN: Retrospective case series. METHODS: A retrospective study was conducted including all patients treated for salivary gland lithiasis by minimally invasive surgery, such as sialendoscopy, intracorporeal lithotripsy, extracorporeal lithotripsy, transoral approach, and combined approach in our Department. We analyzed the recurrence rate of salivary lithiasis, their topography and timeline. RESULT: Three hundred four patients were included in this study, the mean age was 49 years (range 12-90 years), and the mean duration of follow-up was 19.8 months (range 0-66 months). Fifteen patients (5%) presented secondary lithiasis. In all but one case, recurrences involved the same gland as primary lithiasis, and most frequently the submandibular gland. Recurrences occurred from 3 to 46 months postoperatively. Fourteen patients, who presented recurrence, had been initially treated by transoral approach. Recurrent lithiasis were treated by transoral approach or submandibulectomy. CONCLUSION: Salivary gland lithiasis recurrence was rare after minimally invasive salivary gland surgery. This study reinforced the concept that salivary gland lithiasis should be considered as a duct pathology. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:794-799, 2021.

ABSTRACT

BACKGROUND: Although many studies focus on short-term side effects of radioiodine therapy, almost none studied long-term side effects. We assessed radioiodine long-term salivary side effects after radioiodine treatment for differentiated papillary thyroid carcinoma and compared it to short-term morbidity within the same population. METHODS: A standardized self-administrated questionnaire was submitted in 2019 by patients treated with radioiodine between January 2011 and December 2012. These patients had already answered the same questionnaire 6 years before. RESULTS: Our study showed a significant reduction for salivary side effects: discomfort in submandibular or parotid area, swelling, pain, a bad or salty taste in the mouth, allowing to get back to a "normal" diet. CONCLUSIONS: Our study suggests that a significant rate of patients will recover from I131 therapy salivary side effects. As almost 30% of these remissions happened during our late stage follow-up, we highlight the necessity of a long-term follow-up in these patients.
