Combined endoscopic and intra-oral approach for chronic maxillary sinusitis of dental origin—a prospective clinical study
Aims and objectives
The traditional Caldwell-Luc approach for maxillary diseases has been criticized for its shortcomings such as removal of a large amount of bone, numbness of the teeth, flap dehiscence, and recurrent sinusitis. On account of its minimal invasiveness and physiological approach, functional endoscopic sinus surgery (FESS) has come to replace the Caldwell-Luc approach for the treatment of chronic rhinosinusitis. Chronic maxillary sinusitis of dental origin (CMSDO) is a less common variant on the chronic rhinosinusitis spectrum whose treatment involves simultaneous management of both the diseased maxillary sinus and the dental source of infection. Thus, this study was undertaken to assess the efficacy of FESS when combined with an intra-oral approach for the treatment of CMSDO.
Material and methods
Eighteen patients with CMSDO in the age group of 18–50 years were treated with a combined endoscopic and intra-oral approach (buccal advancement flap with/without buccal fat pad) in this study. The patients were followed up for a total duration of 18 months. The primary outcome measurements were the SNOT-22 Quality of Life questionnaire and the Lund and Mackay CT Scan Scoring Criteria. The Friedman test was used to assess improvement in the above variables and the level of significance was set at 0.05.
Observations and results
There was a statistically significant reduction (p < 0.05) in both the above parameters at all post-operative intervals. Two patients presented with epistaxis (immediate post-operative phase) and synechiae (second week follow-up interval). Both complications were successfully resolved. Two patients showed recurrence at the 6th-month interval for which they underwent revision surgery successfully. Overall, results were maintained even at the 18th month follow-up interval.
The endoscopic approach appears to be a reliable, minimally invasive technique associated with less morbidity and stable long-term results. Thus, a multi-disciplinary approach between maxillofacial surgeons and otolaryngologists is essential in the treatment of CMSDO.
