Background: Mucoceles of the maxillary sinus after Caldwell-Luc procedure develop by entrapment of mucosa. Specially mucoceles far laterally were being revised by a second transoral approach. This procedure carries the risk of damaging the infraorbital nerve. In addition the problem of scarring at the bottle neck between the lateral recessus and the nasal cavity with reclosure remains.
Methods and patients: In 3 patients with a mucocele of the maxillary sinus 4-25 years after Caldwell-Luc operation an endonasal endoscopic opening of the mucocele was performed. In addition a silicon spacer was placed for 6 months.
Results: Twelve to fifteen months postoperatively all 3 patients still had an uneventful maxillary sinus according to the data of endoscopy, computer-tomographic or MRI-examination.
Conclusions: The endoscopic approach and the long standing placement of a splint seems to be a valuable alternative to a renewed somewhat risky Caldwell-Luc approach.
