“…1 They occur principally in the third or fourth decades of life with a male predilection. 1 Mucoceles result from the blockage of the sinus drainage secondary to inflammation, trauma, anatomical aberrations, tumours. chronic rhinosinusitis, allergic disease and craniofacial disease are the most common cause of mucocele formation.…”

Introduction: Mucoceles are cystic masses developing after obstruction of the sinus ostium. The symptoms are not specific. Computed Tomography scan (CT scan) and Magnetic Resonance Imaging (MRI) confirm the diagnosis. Objectives: We herein review the radiologic characteristics of mucoceles in CT scan and MRI. Materials and Methods: We report a retrospective study of 43 patients diagnosed with paranasal sinuses mucoceles. CT scans were performed for all patients, but MRI was carried out only in selected cases. Results: Our study was constituted of 27 males and 16 females with a mean age of 47 years. The CT scan appearence of mucoceles were in all cases as a well circumscribed expansile sinus mass with an effect on the neighbor bone structure. This mass was hypodense in 26 cases, isodense in 14 cases and hyperdense in 3 patients. The paranasal sinuses most frequently affected in our series were the fronto-ethmoidal sinuses. The most affected bone eroded was the lamina papiracea. Intracranial extension was seen in four cases. CT scan allowed to predict the cause of mucoceles in some cases and to provide information about anatomic variants. MRI was realized for 15 patients in addition to the CT scan. It allowed to study the extension of mucoceles to the neighboring organs especially orbital and endocranial ones. Conclusion: The presentations of mucoceles on imaging are quite variable. CT scan provides precious information about the location, bone erosion and extension of the mucoceles. MRI is indicated in some cases especially in cases of orbital or cranial extension.

“…However, patients as young as 4 have been reported [1]. There is a slight male predilection [7]. Clinical symptoms may include headache, diplopia, visual impairment, nasal obstruction, and a variety of other symptoms related to involvement of the various cranial nerves and the pituitary gland, depending upon the location of the individual mucocele.…”

“…Squamous metaplasia and reactive bone formation can appear in areas adjacent to cystic epithelium. Occasionally, there is activation of T h2 lymphocytes due to increased expression of IL-12 and IL-2 which can lead to an increased inflammatory response [7].…”

“…Conservative surgical care involves marsupialization of the mucocele with maintenance of adequate sinus drainage, which relieves the symptoms and prevents recurrence. This is now done most often by endoscopy using medial maxillectomy with mucosal flap [7,10,11]. With Endonasal sinus surgery, Bockmuhl and colleagues [5] reported that 98.4% of 185 patients were long-term disease free.…”

Journal of Surgery IntroductionSinus mucoceles are true cysts lined by pseudostratified respiratory epithelium and have a mucous or mucopurulent content [1]. They are produced by the accumulation of mucous secretions within tissue or the sinus cavity, secondary to obstruction of the sinus ostea (obstructive type). By definition, if there is partial obstruction of ducts of seromucous glands within the sinus wall, such true cysts are called retention cysts of the maxillary sinus. While retention cysts are typically asymptomatic and incidental findings, the obstructive type sinus mucocele is capable of significant expansion and destruction [2]. Chemical mediators, such as prostaglandin E2 and collagenase, are released at the capsule of the mucocele, possibly causing bony destruction and allowing the mucocele to expand into adjacent structures [3]. They can lead to exophthalmos, limited eye movement and headaches in patients. Rarely, ethmoid sinus involvement may induce oculomotor nerve paralysis. The frontal sinus is most commonly affected, whereas involvement of sphenoid, ethmoid, and maxillary sinuses are unusual sites of involvement [4]. We present a case of obstructive type sinus mucocele of the left maxillary sinus in an 18 year old female. Case ReportAn 18 year old Cambodian female presented to Children's Surgical Center at the National Rehabilitation Center in Phnom Penh, Cambodia for evaluation of left maxillary sinus swelling and discomfort (Figure 1). In addition to notable facial asymmetry, the enlargement was associated with elevation of the left orbit. No visual disturbances, however, were noted. A computerized tomography (CT) scan without contrast was ordered and showed a cystic process of the left maxillary sinus ( Figure 2) and treatment was planned for February 2014. An 18-guage needle was chosen for aspiration through an existing bony defect apical to teeth 12-14, returning a mucoid material. Subsequent surgical access was gained in the same area and, upon entry into the sinus, the membrane appeared normal. The lumen of the sinus was entirely filled with a gray, viscous, mucoid material. This, along with a portion of the sinus lining, was removed and submitted for histopathologic examination. An antrostomy of the sinus was completed prior to closure. Recovery and healing were uneventful. AbstractObjective: Sinus mucoceles are true cysts that develop secondary to obstruction of sinus ostea and can be associated with significant morbidity. Study Design. We present a case of obstructive-type sinus mucocele of the maxillary sinus, including clinical, radiographic, histologic findings, as well as treatment.Results: An 18 year old female presented for evaluation and management of maxillary sinus swelling. A diagnosis of sinus mucocele was rendered after clinical, radiographic, surgical and histopathologic examinations. Recurrence developed within four months of the initial surgical intervention. Conclusions:Sinus mucoceles may be associated with significant morbidity and are currently managed most oft...

“…Although many cases of idiopathic and/or postoperative PSMs have been reported [2,3,5,6,7,8,9], few case reports have described posttraumatic PSM [10,11,12]. When we previously studied PSMs, we had to exclude posttraumatic PSM because the diagnosis was definitively achieved in only 1 patient at that time (1995-2008) [13].…”

Aim: The purpose of this study was to analyze the clinical features of patients with posttraumatic paranasal sinus mucocele (PSM). Subjects and Methods: Between 2009 and 2013, we performed endoscopic sinus surgery (ESS) on 68 patients with PSM at the Department of Otolaryngology - Head and Neck Surgery at Hyogo College of Medicine. Five male patients (age range, 45-76 years) with posttraumatic PSM were analyzed retrospectively. Diagnosis was based on the history of injury and radiological findings. Results: Posttraumatic PSM was found in 7% (5/68) of patients. The mean interval from injury to diagnosis was 28.4 years. All patients had frontal sinus mucocele. Four patients had symptoms of headache, diplopia, visual field defect, and forehead swelling, and 1 patient was asymptomatic. ESS was performed under general anesthesia in all cases, and the symptoms improved postoperatively. Reoperation was required in 1 patient (20%) because headache developed with obstruction of the frontal drainage route 7 months after ESS. Conclusions: Posttraumatic PSM was the least frequent form of PSM and was located predominantly in the frontal sinus, causing symptoms long after the forehead injury. The important lessons to be learned for treating posttraumatic PSM are to obtain a detailed history and to enlarge the route to the cyst to avoid its recurrence.
