Mucosal Cysts of the Maxillary Sinus in Solid Organ Transplant Population: Computerised Tomography Follow-Up Results

Abstract

Background: The clinical significance of maxillary sinus mucosal cysts in liver and kidney transplant recipients remains unclear.Aim: To investigate the course of maxillary mucosal cysts in liver and kidney transplantation patients. Study Design: Retrospective clinical studyMethods: Paranasal sinus computed tomography scans of 169 renal and 43 hepatic transplant recipients were reviewed. The incidence, size and growth characteristics of maxillary mucosal cysts in the renal and hepatic transplant population were noted.Results: Overall incidence of maxillary sinus mucosal cyst in transplantation patients was found to be 24.5%, with a male to female ratio of 2:1 (p<0.05). Follow-up views of 26 patients showed that the size of the cysts increased in 19, decreased in 4, and remained the same in 3 patients. Mean growth rate of the cysts was calculated to be 6.30 ± 7.02 mm 2 per month. Most of the cysts were located on the inferior wall of the maxillary sinus. Conclusion:Incidence of the maxillary mucosal cysts in renal and hepatic transplant recipients does not differ from general population, but these cysts have a greater tendency to grow. Specific measures are not needed for isolated, asymptomatic maxillary mucosal cysts in transplant populations.

Otorhinolaryngological dysfunctions induced by chronic kidney disease in pre- and post-transplant stages

“…According to Aydin et al, the incidence of MSMC did not differ between the cohort of organ recipients and general population [46]. Nevertheless, the authors found higher tendency of MSMC enlargement in RTRs than in healthy population [46].…”

“…Nevertheless, the authors found higher tendency of MSMC enlargement in RTRs than in healthy population [46]. They concluded that it could have been a result of immunosuppressive therapy and higher frequency of upper respiratory tract infections in organ recipients [46]. This observation should be analyzed with caution because of the lack of other studies on this subject.…”

“…Maxillary sinus mucosal cyst (MSMC) is a benign and usually asymptomatic condition caused the obstruction of the duct of a seromucinous gland at sinus mucosa that leads to mucus collection and cystic dilatation of the affected gland [46]. It has not been established yet whether MSMCs are only a completely incidental finding, or whether they are an indicator of underlying sinus pathology [46].…”

The Trend of Changes in Paranasal CT Scan in Patients with Hematologic Malignancy Under Chemotherapy

“…Routine paranasal sinus CT scans are not feasible in patients scheduled for organ transplant according to the high rate of false-positive results; therefore, we did not perform radiological imaging methods in every transplant candidate. This means that our patients might already have maxillary mucosal cysts before transplantation (10).…”
