I'm sorry to hear of this with Lucy. I'm not aware of the benefit of antihistamines for laryngeal paralysis and so I wonder if the Benadryl is addressing an allergy that exists concomitantly with her LP. Acute general treatment might involve supplemental oxygen, reducing laryngeal edema with a glucocorticoid such as prednisolone or dexamethasone or the diuretic furosemide. Sedation with acepromazine or butorphanol is valuable in stressed dogs. For chronic treatment, unfortunately nonsurgical approaches are rarely sufficient long term. These approaches involve weight loss, exercise restriction, stress reduction, and treatment of underlying disease (which the Benadryl, Deramaxx, and thyroid supplementation appears to be addressing).

Unilateral arytenoid lateralization is recommended because higher complication rates are seen with other surgical options but it's not without its possible complications:

Aspiration pneumonia is reported in 8-33% of dogs (depending upon which study you read) after unilateral arytenoid lateralization. Cough/gagging is seen in 10-16% of dogs. Respiratory distress requiring temporary tracheostomy and postoperative megaesophagus (a ballooning out of the normally rigid esophagus) have been seen as well.

Please clarify "doxwpen" and I'll adress it after I hear from you.
