Objectives: Postoperative cheek cyst (POCC) is a late postoperative complication of radical maxillary sinus surgery including the Caldwell-Luc (C-L) operation. The present study aimed to evaluate the therapeutic outcomes of surgical treatment for POCC and to assess the clinical factors correlated to these outcomes.
Methods: This study included 57 patients (67 nostrils) diagnosed with POCC who underwent surgical drainage. The medical records of the patients were retrospectively reviewed for radiological findings, treatment modalities, residual symptoms, and recurrences.
Results: In total, 30 patients were male and 27 patients were female with a mean age of 55 years, and the patients were usually diagnosed with POCC 28.2 years after radical surgery. Endonasal endoscopic marsupialization was performed via inferior meatal antrostomy, and if possible, middle meatal antrostomy was performed at the same time. In patients with cysts that were difficult to reach using an endonasal endoscopic approach, additional open C-L approaches were performed. The median follow-up period was 19.4 months. Overall, adequate drainage and symptomatic relief were achieved in 91% (61/67) of the patients. The recurrence rate was significantly higher in patients who had anterolateral POCC. Failure to achieve symptomatic relief was correlated to a smaller cyst and the use of the open C-L approach for drainage.
Conclusion: The location and size of the cyst as well as the use of the open surgical approach were important factors in predicting the therapeutic outcome of POCC. The time point of treatment and surgical approaches should be based on the above-mentioned findings.
