Beckwith-Wiedemann syndrome (BWS) is characterized by exomphalos, macroglossia, and gigantism. Macroglossia is observed in 97.5% of BWS cases. Here we report the case of a patient with BWS who needed respiratory management following tongue reduction. An 18-year-old man with macroglossia was referred to our department due to concerns of relapse after orthodontic treatment. He had a history of tongue reduction in infancy, and recurrent macroglossia was observed with growth. The patient underwent a tongue reduction following diagnosis of macroglossia. However, immediately after surgery, obstruction of the upper airway due to swelling of the tongue was noted and it was decided to re-intubate the patient. As swelling improved on the second day of surgery, extubation was performed and a nasal airway was inserted. The nasal airway was extubated on the third day of surgery. No particular respiratory problems were observed. Oral ingestion was initiated on the fourth day. In cases of tongue reduction, perioperative management is important considering the possibility of re-intubation for upper airway obstruction.

Purpose:The purpose of this study was to consider the tongue pressure production during swallowing in patients with mandibular prognathism after orthognathic surgery. Methods:The subjects were 10 female patients with mandibular prognathism after orthognathic surgery(age range, 18y6m–25y10m; mean age : 22.6 years ; after surgery), 10 female volunteers with normal occlusion (age range, 20y0m–24y2m; mean age : 21.7 years ; normal occlusion), and 10 female patients with mandibular prognathism(age range, 16y3m–22y7m; mean age : 20.2 years ; mandibular prognathism patients). The tongue pressure in five parts at the time of swallowing 4 ml of tasteless and odorless jelly was measured after attaching sensor sheets on the palate of each subject. Features of tongue pressure waveforms, the time series of tongue pressure production, the duration of tongue pressure, and the maximum tongue pressure value were evaluated. Results:The tongue pressure waveforms showed a similar tendency between the after-surgery patients and the normal-occlusion patients. The tongue pressure waveform rose at each measurement location and peaked at 200–400ms. It then gradually declined and disappeared. The incidence of a double-peak tongue pressure waveform was more frequent in the mandibularprognathism patients. Although the time series of tongue pressure production was the same for the three groups, the maximum tongue pressure value at all channels was lower in the after-surgery group and the mandibular-prognathism patients than in the normal-occlusion patients. Conclusions:The tongue pressure waveform was due to changes of their morphological characteristics after orthognathic surgery. But the maximum tongue pressure value at each location was lower compared with patients with normal occlusion. These results suggest that, in patients with mandibular prognathism after surgery, the tongue as a whole may remain in a lower position during swallowing.

In Japan, the aging rate exceeds 25％ and a super-aging society has developed; the situation is expected to continue in the future. Not only adolescents but also middle-aged and/or elderly patients undergoing orthognathic surgery are gradually increasing. There are reports on orthognathic surgery for jaw deformity patients with multiple teeth defects, but no reports on two-jaw surgery in maxillomandibular edentulous patients in Japan. Although the present maxillomandibular edentulous patient was in their 30s, two-jaw surgery was performed to acquire stable occlusion, enable the use of stable dentures, and improve esthetics. A denture fitting the current alveolar ridge was created for surgical planning, then a duplicate denture in which the crown of the denture had been replaced with a contrast-enhanced resin was used. The patient wore the denture and an X-ray photograph was taken. This method made it possible to plan the amount of movement and intermaxillary fixation during surgery. In addition, the patient had a risk of dialysis, but there were no problems during the perioperative period. The patient was postoperatively very satisfied with the treatment outcome. It is the number of maxillomandibular edentulous cases in whom orthognathic surgery is applied will increase in the future.
