Transpalpebral Frontal Sinus Septectomy: Feasibility and Results.

Background Transpalpebral frontal septectomy (TFS) can be performed for unilateral frontal sinusitis drainage (into the contralateral healthy frontal sinus) or to provide access to the lateral extent of the contralateral frontal sinus. This procedure has demonstrated its usefulness in several problematic situations for the endoscopic surgeon. Objective The main objective of our study was to evaluate the feasibility of TFS. Secondary objectives were to define outcomes, early and late complications, contraindications, and failure rates of the TFS. Methods We reviewed patient demographics including age and gender, indication for frontal septectomy, prior surgeries, failure rates and necessity of revision surgery, early and late complications, and the side of the approach (ipsi- or contralateral to the frontal sinus pathology). Twenty patients who had undergone TFS were included. Patients were classified into 2 groups according to the surgical indication: group 1-TFS performed for unilateral frontal sinusitis to drain a frontal sinus in the contralateral frontal sinus; and group 2-TFS performed to provide access to the lateral extent of the contralateral frontal sinus. Scarring was assessed using the SCAR-Q questionnaire. Results TFS was performed on all patients in Groups 1 and 2 (success rate = 100%). No patients had recurrence of the pathology 6 months after surgery (0%). No patient needed revision surgery (0%). One complication (frontal hypoesthesia) was reported 6 months after surgery. Mean SCAR-Q score was 99.3 +/- 2.5 (min = 91/100, max = 100/100). Conclusion TFS was feasible for all patients in this study. This procedure permits drainage of the frontal sinus and gives access to the lateral extent of the contralateral frontal sinus, without visible scarring, and with few lasting complications. Authorization to conduct this study was obtained from the Ethical Committee of our institution (APHM, n degrees 2019_65).
