抄録

今回われわれは, 生下時から顎関節雑音を認めた3症例を経験したので報告する。<BR>症例1: 生後5日, 女児。出生後より哺乳時に顎関節雑音があることに母親が気づき当科初診。哺乳時両側顎関節にクリッキングを認めたが哺乳障害は認めず。経過観察を行い, 約40日後の再診時にはクリッキングは消失していた。症例2: 生後23日, 男児。生後3日目, 授乳開始した際右側顎関節の雑音に気づく。当初母乳の哺乳困難であったため当科初診。開閉口時右側顎関節にクリッキングを認めたが哺乳困難はなく, 他の異常も認めないため経過観察とした。症例3: 生後3か月, 女児。出生直後より下顎を前方へ動かした際の顎関節雑音に母親が気づき, 症状続くため当科初診。症状はクリッキングのみであったため観察とした。<BR>乳児における顎関節雑音は, ほとんどの場合疼痛などを伴わず経過観察のみ行われていたが, 原因, 病態, 経過等不明な点が多く今後も長期にわたり経過観察が必要であると思われた。

We report on three newborn babies with temporomandibular joint (TMJ) clicking.<BR>Case 1: A 5-day-old girl was referred to our clinic for examination of TMJ clicking. Her mother noticed bilateral TMJ clicking during nursing. The infant could open her mouth normally and did not seem distressed by the clicking or by palpation. Radiographs were normal. No treatment was performed. The TMJ clicking disappeared within 40 days.<BR>Case 2: A 23-day-old boy with right TMJ clicking, that was noticed by his mother after the beginning of nursing, was referred to our clinic. The clicking occurred during mouth opening and closing. There was no other abnormality. He had no difficulty nursing and had grown well, so no treatment was performed.<BR>Case 3: We examined a three-month old girl with bilateral TMJ clicking. Soon after her birth, she was noticed to have TMJ clicking when her mandible protruded, and the sound had continued for three months. The clicking was also detected during mouth opening by palpation. She seemed to have no limitation of mouth opening, TMJ pain, or abnormal development. She was treated by observation only.<BR>Little is known about TMJ clicking of newborns at present, and further reports and examinations will be needed.
