Caldwell-Luc operation: long-term results and sequelaes.

Out of 65 patients with sinusitis, treated with Caldwell-Luc operation 58 (43%) had more or less pronounced postoperative complaints at the follow-up 4-7 years postoperatively. The patients could be divided into group A 47/65 where all were satisfied with the result of the operation and group B 18/65 with more pronounced complaints, such as facial and dental par/hyperesthesia or neuralgia of nervus infraorbitalis. Persisting antrostomy was found in 82% in group A and in 37% in group B indicating that an open antrostomy is of importance for the long time result.
