Unsatisfactory scarring stood out in about 2.4% of patients. This occurred in 31.0% after a pre-auricular incision, in 28.6% after a retromandibular incision, in 4.8% after a submandibular incision, and in 0.0% after a peri-angular incision. In 35.7% the skin incision was not clearly described.
A sialocele was seen in 2.3% of all operations sides, of which all occurred after a transparotid approach, and a salivary fistula in about 4.3%, of which 93.7% were after a transparotid approach. Sialoceles and salivary fistulae occurred mostly after retromandibular skin incisions (61.1% and 46.0% respectively).
Frey syndrome was present in 0.7% of the sides, 33.3% of which were transparotid, and 50.0% non-transparotid; 16.7% were unknown. The skin incision used in most cases was the retromandibular incision (66.7%), after which came pre-auricular (16.7%), and the submandibular (16.7%).
An infection of the wound occurred in about 2.7% of the operations sides, in 39% of these cases a transparotid approach was used. Retromandibular skin incision resulted in the highest rate of wound infections (44.1%), followed by pre-auricular (10.2%), submandibular (6.8%) and peri-angular (6.8%).
A hematoma occurred in 1.3% of the operations sides. In 66,7% of these cases a transparotid approach was used, in 11.1% a non-transparotid approach, and in 22.2% the subcutaneous approach was not described. A retromandibular skin incision was used in 22.2%, in 11,1% a periangular incision, and in 66,7% the incision was not specified.
Sensory disturbance of the great auricular nerve occurred in 6.7%, in the majority of the cases after a transparotid approach (79.2%).
