Acromegaly is caused by growth hormone excess owing to a pituitary adenoma after completion of growth and tends to lead to mandibular prognathism. In this paper, two patients with mandibular prognathism caused by acromegaly and treated by surgical-orthodontic treatment are reported. The first case was a 36-year-old male who was referred to our hospital to correct mandibular prognathism and malocclusion after resection of the tumor in the pituitary gland. The second case was a 26-year-old male who was referred from an orthodontic clinic for orthognathic surgery. He had not been diagnosed as acromegaly but a typical double-floor of the Turkish saddle was found in the lateral cephalogram. Blood tests revealed acromegaly. Surgical-orthodontic treatments were performed after resection of the pituitary adenoma and confirmation of normal level of blood growth hormone (GH) and somatomedin C. In both cases, multi-bracket appliances were worn and bimaxillary osteotomy (Le Fort I osteotomy for maxillary advancement and bilateral sagittal splitting ramus osteotomies for mandibular setback) was carried out to secure the intraoral space for the enlarged tongue. After post-surgical orthodontic treatment, the treatment results were good and stable in both cases. These cases showed that surgical-orthodontic treatment for patients with acromegaly after pituitary adenoma resection is reliable. The importance of careful examination of the craniofacial shape in patients with mandibular prognathism to detect acromegaly is emphasized.

The Japanese Society for Jaw Deformities performed a nationwide survey from 2006 to 2007 and the results were reported in 2008. In the last 10 years, new surgical procedures and medical devices have been developed and brought major changes to surgical orthodontic treatment. Accordingly, we need to assess the current status of surgical orthodontic treatment.A nationwide survey of surgical orthodontic treatment between April 2017 and March 2018 was carried out and 99 surgical facilities and 64 orthodontic facilities were enrolled in the survey. The number of patients who received orthognathic surgery was 3,405, about 69% of whom were diagnosed with mandibular protrusion. Before the surgery, 3D-simulation was performed for about 40% of patients at both surgical and orthodontic facilities. Computer-aided design and computer-aided manufacturing (CAD/CAM) wafers were used at 12.1% of surgical facilities and at 17.7% of orthodontic facilities. Sagittal split ramus osteotomy (SSRO) was performed in 2,768 patients (85.5%) and Le FortⅠosteotomy in 1,829 patients (56.5%). Blood loss during the surgery was reduced compared with that in the previous survey. Autologous blood transfusion tended to be performed in cases as necessary such as surgery for maxilla and anemia of the patient. Duration of intermaxillary fixation and hospital stay were also shortened. This survey revealed the current status of surgical orthodontic treatment in Japan in comparison with the previous survey.

現在,口蓋裂は手術法の進歩,言語管理の徹底により,その多くが鼻咽腔閉鎖機能を獲得し,正常な構音発達を遂げている.初回手術のみで鼻咽腔閉鎖機能を獲得するものは90%前後とする報告が本邦では多い.残りの数%は,初回手術後も十分な鼻咽腔閉鎖機能が獲得できず,その多くは二次手術が必要となる.その際われわれは,鼻咽腔閉鎖機能改善を目的として,咽頭弁手術を行ってきた.鼻咽膣閉鎖機能不全が疑われる症例には,4~5歳に発音時にセファログラムおよび鼻咽腔ファイバースコープ下の鼻咽膣運動の評価を行い,鼻咽腔閉鎖機能不全症を最終的に判定し,咽頭弁手術を施行している.今回われわれは,就学前に咽頭弁手術を施行し,5年以上経過観察を施行した37症例について,術後の合併症および言語成績に関し検討を加えた.その結果,1年後に全例に開鼻声の減少などの改善を認め,日常会話レベルでも鼻咽腔閉鎖機能に問題が無くなったのは,二次手術例で約83%,5年後では約92%と良好な結果を示した.咽頭弁術後も閉鎖機能不全を残した症例で,術式による差は特に認められなかった.むしろ,こうした症例の多くに精神発達遅滞や,心奇形など,他に奇形を伴っていることが特徴的であった.合併症として,鼻閉・口呼吸が術後1年目で7例に,5年目でも4例に認められた.術後,呼吸困難や睡眠時無呼吸症を呈した症例はなかった.また術後5年目までに鼻咽腔閉鎖機能不全を再発した症例はなかった.今回の調査では,重篤な合併症は認められなかったが,扁桃肥大や小顎症などに対しては術前に睡眠時ポリグラフ検査などが必要と考えられる.また術後の顎発育抑制についても,慎重な経過観察が今後とも必要と考えられる.

We describe a case of lacrimal sac fistulae with left cleft lip and palate. A congenital lacrimal sac fistula is a rare disorder in which a fistulous tract connects the skin to the common canaliculus or to the lacrimal sac, located just inferior to the medial canthal angle.A 12-year-old boy had 1) bilateral congenital lacrimal sac fistulae, 2) cleft lip and palate and 3) hypospadis. He had no paticular family history. With the patient under general anesthesia, a fusiform incision was performed, and the lacrimal sac fistulae were excised. Alveolar bone grafting was performed concurrently. Histologically, the lacrimal sac fistulae consisted of unkeratinized squamous epithelium and connective tissue with inflammatory lymphocytes. Patients with lacrimal sac fistulae, cleft lip and palate, and hypospadia have not been reported previously.These findings suggest that lacrimal sac fistulae may be related to congenital malfusions such as cleft lip and palate.
