Partial Resection of the Sternocleidomastoid Muscle for the Congenital Muscular Torticollis / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: This is a retrospective study determining the surgical result of the partial resection of the sternocleidomastoid (SCM) muscle for the congenital muscular torticollis. OBJECTIVES: To evaluate the efficacy of the partial resection of the sternocleidomastoid muscle for the correction of the congenital muscular torticollis. MATERIALS AND METHODS: We reviewed 19 patients who were treated by the partial resection of the sternocleidomastoid muscle from 1990 to 1997. The mean age at the time of the operation was 8 year 3 months. Each patient was examined the range of the motion of the neck for the functional results by the modified Ling's criteria, and the tilt of the head, facial asymmetry, presence of the lateral band, loss of the sternomastoid column and quality of the scar for the cosmetic results by the modified Ling's criteria. The over-all cosmetic and functional results were analyzed by the criteria similar to those described by Canale et al. RESULTS: Functionally, 5 patients (26.3%) were excellent, 10 (52.6%) good, 2 (10.5%) fair, and 2 (10.5%) poor. Cosmetically, 7 patients (30.8%) were excellent, 9 (47.4%) good, 1 (5.3%) fair, and 2 (10.5%) poor. The complication was one lymphatic leakage. Seven of 8 patients were good and one patient was fair under the age of 5. Six of 7 patients were good and one patient was poor between the age of 6 and 10. Two of 4 patients were good and two patients were poor over the age of 11. CONCLUSION: The partial resection of sternocleidomastoid muscle for the congenital muscular torticollis would be recommendable, because it is a simple, safe procedure and usually produces satisfactory results. All partial rescetion of the sternal and clavicular head of the sternocleidomastoid muscle may prevent the unsatisfactory cosmetic result which is lateral band due to the clavicular head of the sternocleidomastoid muscle. The good results were achieved in case of under the age 10 years.
