Mucosa lines the frontal sinus outflow tract (FSOT) from the frontal sinus to the nasal cavity and any obstruction to the flow of mucus can lead to complications such as mucocele formation or chronic frontal sinusitis. If the FSOT or posterior cranial vault is not damaged, reestablishment of the aesthetic contour of the frontal bandeau becomes the primary concern. There are several materials that have been proposed for treatment of frontal bone defects. Technological advances such as computed tomography (CT) scan, computer assisted design (CAD), and computer assisted manufacturing (CAM), have led to the development of three-dimensionally printed patient-specific implants. Poly-Ether-Ketone-Ketone (PEKK) is a biocompatible material from the same polyaromatic semicrystalline polymer family as Poly-Ether-Ether-Ketone (PEEK). Patient specific implants have given way to smaller surgical incisions that enable the implant to be slipped into the bony defect to reestablish contour of the frontal bandeau and secured with lag screws. The aim of this study is to describe a case of frontal bone defect reconstruction with PEKK implant via a lateral nasal/Lynch incision.</p></div>","PeriodicalId":38030,"journal":{"name":"Oral and Maxillofacial Surgery Cases","volume":"9 2","pages":"Article 100293"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45946305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But, in recent years, research suggests that a minimum of at least 2mm of keratinized mucosa is recommended for the maintenance of peri-implant health. The latest systematic reviews on this topic are largely in favor of keratinized mucosa, as are the recommendations of some expert panels. The present paper presents a novel technique for peri-implant flap suturing that can be used in combination with soft tissue augmentation procedures, such as laterally positioned flaps, roll-flaps, and decellularized dermal matrix xenografts. The technique stabilizes the flap on the buccal surface of the healing screw or the emergence profile of the tissue-level implant with a circumferential continuous mattress design that is anchored on the buccal margins and/or periosteum with a final knot. The technique is carried out with a sterile 6/0 synthetic absorbable glyconate monofilament surgical suture (Monosyn, Bbraun, B. Braun Milano S. p.A., Via Vincenzo da Seregno, 14, 20,161 Milan, Italy). This type of suture is ideal, as it slides smoothly through the tissues and allows for the ideal adjustment of the tension and the position of the flap margins until the final knot is positioned. Furthermore, these augmentative procedures make use of second-intention healing and mattress sutures are always ideal to stabilize flap margins without excess tension in such cases. This case series involves patients with a reduced band of keratinized mucosa and, as such, in need of augmentative flap procedures.</p></div>","PeriodicalId":38030,"journal":{"name":"Oral and Maxillofacial Surgery Cases","volume":"9 2","pages":"Article 100311"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47943570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SCC of the head and neck show cervical lymphatic metastasis, which is the most important prognostic factor for the long-term outcome of these patients.
