ABSTRACT

Mucous retention cyst of the maxillary sinus is a benign pathologic lesion. Most of the cases appeared asymptomatic and discovered accidentally during radiographic examinations. However, some cases present with symptoms such as; dizziness, headache, congestion, allergy, and paresthesia.

The aim of this report was to present successful conservative surgical management of a large maxillary mucous retention cyst associated with a deep pocket of a non-vital maxillary right second molar. Case report A 38-year-old male patient presented to the dental clinic with dull pain and suppuration around tooth #17. Clinical and radiographic examinations demonstrated generalized plaque and calculus deposits, BOP, gingival recession, and a large radiographic cystic area apical and lateral to tooth #17. A deep pocket, (PD) 15mm, was noted on #17 mesio-buccal, at this site there was suppuration, BOP, and grade II mobility. A vitality test indicated that the tooth was non-vital and symptomatic upon percussion. Following the extraction of the infected tooth, an excisional biopsy of the cystic lesion was performed. Histopathological examination confirmed the diagnosis of a mucous retention cyst. Case management involved extraction of the infected tooth, socket degranulation, and cyst enucleation. The sinus cavity was packed with gauze impregnated with bismuth subnitrate iodoform paraffin paste (BIPP). Uneventful rapid healing was observed. A cone-beam computed tomography (CBCT) scan obtained 1 year postoperatively demonstrated complete resolution of the cystic cavity. Clinically, complete soft tissue healing was evident. Conclusion This case highlights the successful management of a mucous retention cyst using a combination of extraction, cyst enucleation, and BIPP packing, with 12 months of follow-up showing stable results.
