Bone regeneration after sinonasal mucocele marsupialization: What really happens over time?
The Laryngoscope, 2015Co-Authors: Paola Terranova, Apostolos Karligkiotis, E. Digilio, Francesca Basilico, Elena Bernardini, Andrea Pistochini, Maurizio Bignami, Paolo CastelnuovoAbstract:Objective To evaluate the necessity of reconstructing the eroded bony boundaries after mucocele marsupialization when the Mucoperiosteum has been spared. Study Design Retrospective review of 308 patients treated for a sinonasal mucocele. Of these, 116 showed areas of bone reabsorption in their preoperative computed tomography (CT) scan. Methods Of 116 patients showing one or more areas of bone reabsorption who underwent marsupialization of the mucocele, whether using a purely endonasal endoscopic approach or a combined approach, the common factor was that the Mucoperiosteum of the paranasal sinus had always been spared and the eroded bone had never been reconstructed. After rigorous selection, 12 adult patients were enrolled to undergo a postoperative CT scan in order to verify what had happened to the eroded bone at least 3 years following the surgical marsupialization of the mucocele. Results In 66,6% of patients, the postoperative CT scan showed complete self-reconstruction of bone that had previously been eroded by the mucocele. No enophthalmus, meningocele, or other facial deformities were noted in our selection group, despite not having undergone surgical reconstruction of the bone. Conclusions Even taking into account the small number of patients enrolled in the present study, indications are that there is no need to reconstruct the eroded bone, as would appear from our results that sparing the Mucoperiosteum is enough to enable the bone to regenerate. Nevertheless, larger scale studies of the subject are merited. Level of Evidence 4. Laryngoscope, 125:1568–1572, 2015

endoscopically controlled sinus floor augmentation a preliminary report
Clinical Oral Implants Research, 1997Co-Authors: Wilfried Engelke, Isabell I S DeckweAbstract:: Sinus augmentation has been advocated to be a surgical technique with predictable results in peri-implant surgery. Endoscopic surgery of the maxillary sinus so far has been used as diagnostic procedure. In this paper, the use of endoscopy is described as a low invasive adjunctive technique in sinus floor augmentation. After preparation of the Mucoperiosteum, bone grafts can be placed under endoscopic control between sinus floor and Mucoperiosteum. A laterobasal approach via a small osteotomy and a transalveolar approach are possible for mucosal elevation and graft placement. First clinical results are reported. Endoscopic sinus lift may contribute to a reduction of perioperative morbidity, reduction of oroantral fistulae and control of graft position. The less invasive technique may allow to extend the indication for sinus augmentation.

Surgical repair of hard palate cleft with absorbable membrane: the new surgical technique and its clinical application.
Swiss medical weekly, 2006Co-Authors: En Luo, Shi-cheng WeiAbstract:This study evaluated a new surgical technique with absorbable membrane to repair hard palate cleft without extensive mobilisation of the Mucoperiosteum. From 2001 to 2002, 32 selected patients with complete unilateral clefts underwent this surgical operation. The traditional flap surgical operation was performed at the soft palate, uvula and anterior alveolar cleft. The absorbable membrane was implanted to the hard palate cleft gap to guide the regeneration of the Mucoperiosteum. The patients were followed up for 1-6 months after the operation. The speech assessment was carried out 12 months after the operation. Of 32 patients, 30 were successfully operated by this method and no obvious complications occurred. Primary healing on tissue defect of hard palate was obtained in 27 patients and secondary healing in 3 patients. Eighty percent of the 30 patients had good or excellent speech 12 months after the operation. The operation failed in 2 patients. The surgical technique with absorbable membrane to repair hard palate appears to have several valuable advantages including the decreased area of the hard palate involved and favourable outcome for speech in the majority of cases.
