Evaluation of middle meatal stenting after minimally invasive sinus techniques (mist)

Abstract

Compared with Gelfilm, Merogel MM stents produced less synechia; Merogel retains its position in the MM longer than Gelfilm; and the incidence of postoperative MM synechia can be reduced when absorbable MM stents are used in conjunction with MIST.

Effects of Meropack in the middle meatus after functional endoscopic sinus surgery in children with chronic sinusitis

“…We found no statistically significant difference in infection score at any postoperative visit. This result was similar to the results reported by others [11,20]. The difference in infection rate between the Meropack-dressed and unpacked sinuses was not statistically significant, which could have been due to the bacteriostatic effect of Meropack [21].…”

“…Catalano and Roffman reported the infection rate was 6.4% (6/94) among both Merogel and Gilfilm groups at the first postoperative visit, and that both groups had 0% infection rates at later visits [11]. Miller et al found no statistically significant difference in infection between hyaluronic acid and non-absorbable packing at any follow-up visit [17].…”

“…Intranasal packing with a variety of materials is often applied to prevent postoperative hemorrhage and synechiae between the middle turbinate and lateral nasal wall [7][8][9][10][11]. Biodegradable nasal dressings that obviate the need for removal of nasal dressings are preferable for effective reduction of patient discomfort during postoperative care.…”

Randomized Controlled Trial of Hyaluronic Acid/Carboxymethylcellulose Dressing after Endoscopic Sinus Surgery

“…In a nonrandomized, uncontrolled study, Catalano and Roffman [10] reported that 86% of the sides that had a different HA gel packing (Merogel; Medtronic Xomed, Jacksonville, Fla., USA) placed with a Gelfilm stent did not develop synechiae. In a series of 10 patients, Kimmelman et al [11] demonstrated that a different HA gel sinus dressing (Sepragel; Genzyme) was effective at decreasing synechiae and middle meatal stenosis while improving pain in the early postoperative period.…”

Nasal and sinus endoscopy for medical management of resistant rhinosinusitis, including postsurgical patients

“…46 Discussion of the reasons for different surgical techniques is beyond the scope of this review; however, it is important to examine the surgical ostium for postoperative narrowing as a result of synechiae, edema, thickened mucus, fungus balls, or polyps. [47][48][49] The thickness of the lateral nasal wall at the margin of the surgical ostium should also be noted. This wall is usually a thin structure.…”
