Case Facts & Court Holding
Key Facts & Case Background
Plaintiff Ilene Perin underwent an anterior approach cervical fusion performed by defendant Dr. Robert Hayne to treat protruded cervical discs. The surgery successfully alleviated her pain but resulted in paralysis of a vocal cord, impairing her voice. Plaintiff alleged this was due to injury to the right recurrent laryngeal nerve during surgery. The procedure involved retracting the visceral column, which contains the esophagus, trachea, and the recurrent laryngeal nerve. Defendant denied severing the nerve, stating the visceral fascia was not entered. Expert testimony, including from plaintiff’s expert Dr. Eidbo and defendant, indicated that such nerve injury, while rare (0.2-0.3% of cases), could occur from contusion during retraction of the visceral column despite the exercise of all proper skill and care. Defendant had performed 462 such operations without this complication prior to plaintiff’s surgery. Plaintiff asserted claims of specific negligence, res ipsa loquitur, breach of express warranty (based on alleged assurances of a normal life), and battery (alleging consent was vitiated by lack of warning about specific hazards and that she consented to only one fusion when two were performed).
