Post-trauma mucocele formation in the frontal sinus; a rationale of follow-up

Assessment of Mucocele Formation after Endoscopic Nasoseptal Flap Reconstruction of Skull Base Defects

“…30 Such patients typically present with headache, proptosis, diplopia, nasal congestion, and fluid leakage. [38][39][40] Although mucocele formation is considered a late complication, its timing may be variable depending on the underlying etiology. Postoperative mucocele formation after endoscopic sinus surgery has been reported with average time lapse between 2 and 6 years.…”

“…Postoperative mucocele formation after endoscopic sinus surgery has been reported with average time lapse between 2 and 6 years. 26,39,[41][42][43] Nonetheless, prior reports of mucocele formation after vascularized PNSF repair have been reported at 46 days 31 and at 4 months. 32 Different ideologies exist for the pathogenesis of mucocele formation, because there are a variety of etiologies that lead to sinus obstruction.…”

Clinical Features of Patients Treated with Endoscopic Sinus Surgery for Posttraumatic Paranasal Sinus Mucocele

“…In terms of pathogenesis, posttraumatic PSM is thought to be the least frequent type, whereas postoperative PSM is the most common [17]. Only a few cases of posttraumatic PSM have been reported previously [10,11,12]. In our previous retrospective study about 219 patients with PSM treated over 13 years, posttraumatic PSM was found in only 1 patient (0.5%), compared to postoperative PSM which was found in 79.0% (n = 173) and idiopathic PSM in 20.5% (n = 45) [13].…”

“…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].…”

Delayed development of frontal mucocele after fronto-orbital advancement in a child with craniosynostosis

“…One is that it develops because of progressive spread of the mucosa from the middle meatus or from ethmoid sinus, and the other is that it develops as a result of a certain stimulus in the frontal skull that also separates the inner and outer tables of the frontal bone [7,10]. However, in a study by Lykins et al [11], who performed unilateral frontal craniectomy including the frontal sinus and then filling with hydroxyapatite cement in 12-week-old cats, it was observed that the hydroxyapatite cement changed into bone, hence reforming the coronal suture, but there was no redevelopment of the frontal sinus.…”
