Background: Voice prosthesis is the current standard for post laryngectomy rehabilitation. Several clinical factors can affect the functional outcomes of voice prosthesis. Various complications are recorded with voice prosthesis. Objective: This study aimed to compare the results of primary and secondary provox insertion in patients with advanced laryngeal carcinoma undergoing total laryngectomy. Patients and Methods: Randomized-controlled clinical study included 24 patients with provox voice prosthesis rehabilitation 12 had primary tracheoesophageal puncture and 12 had secondary tracheoesophageal puncture. All patients were evaluated for successful voice restoration and complications rates. Results: Short-term success rate was 92% in the primary group and 83% in the secondary group. Long-term success rate was 83% in the primary group and 75% in the secondary group. Success rates were higher in the primary group but without statistically significant difference. Complications rate in the primary group was 58.3% and in the secondary group 66.6%. Complications rate was higher in the secondary group but without statistically significant difference. Conclusion: Provox voice prosthesis provides consistent and good voice results, which improve with time. Primary provox insertion had better success rates and fewer complications. Periprosthetic leak is the most common complication.
