Mucosal maxillary cysts: long-term subjective outcomes after surgical treatment

Abstract

Mucosal maxillary cysts (MMCs) are usually asymptomatic and are often diagnosed as an incidental finding. The aim of this study is to assess clinical significance of MMCs and the long-term effect of surgical treatment on the symptoms initially addressed to MMCs. The study included a retrospective analysis of 64 patients who had undergone surgery for MMC using a questionnaire focused mainly on the effect surgery had on symptoms. Mean time of follow-up was 79 months. Patients were also divided and compared according to the presence of rhinitic symptoms. Twenty-six patients (63.4%) reported complete disappearance of symptoms, 8 (19.5%) reported improvement, 4 (9.7%) reported no change in symptoms following surgery and 3 (7.3%) reported that symptoms reappeared. Significantly (p = 0.0365) better results were achieved in patients without preexisting rhinitic symptoms. This study supports the opinion that in some cases, MMCs are involved in the development of sinonasal symptoms. Surgical treatment leads, in most patients, to disappearance or improvement of symptoms and the effect is better in patients without rhinitic symptoms.

Calcifying odontogenic cyst associated with an antral pseudocyst: treatment of an uncommon case report and update of main findings

“…APs are solitary, dome -shaped radiopaque masses located on the maxillary sinus floor that can further reduce the size of this anatomical structure. [11][12][13][25][26][27] This finding is consistent with the present case since a veiling of the maxillary sinus caused by the AP was observed, and the central radiopaque area in the maxillary sinus led us to hypothesize a diagnosis of COC for the lesion in the antrum (rather than the periapical one).…”

“…Surgical excision in these cases is unnecessary, as studies have shown no progression or even regression during follow -up. 11,12,25 When present, symptoms range from headaches to face pain and nasal obstruction and discharge. 12,25 In some cases, a positive aspiration mimicking a cystic lesion may be present.…”

“…11,12,25 When present, symptoms range from headaches to face pain and nasal obstruction and discharge. 12,25 In some cases, a positive aspiration mimicking a cystic lesion may be present. 13 Given these clinical and radiographic findings, the literature indicates mucocele of the sinus and odontogenic cysts as differential diagnoses.…”

“…The literature reports that COCs can present at this location and even mimic a sinus mucocele. 3,28 Although APs' etiology is not well understood, other studies report allergies, barotrauma, rhinitis, rhinosinusitis, 12,25 periapical infections, 10,11,25 periodontitis, 10,25 viral infections of the respiratory tract, and mucosal irritations caused by lack of air humidity 13 as possible factors. Since COCs are a noninflammatory odontogenic lesion, they are unlikely to cause APs' development.…”

Mucous retention cyst in maxillary sinus with expansion of maxillary tuberosity

“…The mucous retention cyst (mucocele) of the maxillary sinus is a phenomenon resulting from the retention of mucous present in the mucous glands of the maxillary sinus lining epithelium, being detected as a radiographic finding in the dental examinations by image [12][13][14] .…”
