What's the difference between dissection and myotomy?

Dissection


Definition:

  • (n.) Fig.: The act of separating or dividing for the purpose of critical examination.

Myotomy


Definition:

  • (n.) The dissection, or that part of anatomy which treats of the dissection, of muscles.

Example Sentences:

  • (5) Although the operative technique for longitudinal ileal myotomy has the benefit of simplicity compared with construction of an ileal reservoir, the latter techniques, which have been used clinically on an extensive basis, are more likely to produce a consistent distension that is suitable for fecal storage.
  • (6) This finding is of relevance to the controversy surrounding cricopharyngeal myotomy in combination with pouch excision.
  • (7) Nineteen cases with major resections of the head and neck were treated with laryngeal suspension and cricopharyngeal myotomy in an attempt to allow swallowing function postoperatively and avoid a total laryngectomy.
