Purpose: To report surgical outcome in three patients with abnormal head tilting position induced by nystagmus.
Case summary: (Case 1) A 7-year-old female patient diagnosed with Down's syndrome visited our clinic for right head tilting, chin up and nystagmus. Abnormal ocular deviation was not found. Bilateral inferior rectus recession and superior rectus resection, right superior oblique anterior half tenectomy, left inferior oblique recession were performed. Abnormal head position was improved after surgery. (Case 2) A 7-year-old female patient presenting nystagmus with left head tilting, esotropia and right hypertropia visited our clinic. Right medial rectus recession and right inferior oblique recession, left superior oblique muscle anterior half tenotomy were performed. While head tilting was improved immediately after surgery, right head tilt and left hypertropia were observed after 2 years. Left superior rectus central mini-tenotomy and superior oblique re-attachment of primarily cut-out fiber were performed. After surgery, right head tilting and left hypertropia has decreased. (Case 3) A 3-year-old boy was presented with right face turn and left head tilting with nystagmus. Right medial rectus recession and inferior oblique recession, left lateral rectus recession and superior oblique anterior partial tenectomy were performed. Postoperative head position was improved and strabismus was not found.
Conclusions: Abnormal head position was improved after surgery in three patients who have nystagmus causing abnormal head tilting. Oblique muscle surgery for nystagmus may have good result for correcting abnormal head position.
