With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons prefer transnasal endoscopic management of sinus mucoceles. The aim of this study is to describe the clinical presentation of maxillary sinus mucoceles and to establish the efficacy of endoscopic management of sinus mucoceles. Methods: Between 2003 and 2005, 14 patients underwent endoscopic sinus surgery for maxillary sinus mucocele. The presenting sign and symptoms, radiological findings, surgical management and need for revision surgery were reviewed. Results: There were eight males and six females with an age range of 14 to 65. Ten patients complained of nasal obstruction, five of nasal drainage, five of cheek pressure or pain and one of proptosis of the eye and cheek swelling. The maxillary sinus and ipsilateral ethmoid sinus involvement on computed tomographic studies was seen in 4 patients. Four patients had history of endoscopic ethmoidectomy surgery for ethmoid sinusitis and one had Caldwell-Luc operation in the past. Ethmoidectomy with middle meatal antrostomy and marsupialization of the mucocele was performed in all patients. Postoperative follow-up ranged between 8 to 48 months. All patients had a patent middle meatal antrostomy and healthy maxillary sinus mucosa. No patients need revision surgery. Conclusion: The most common causes of mucoceles are chronic infection, allergic sinonasal disease, trauma and previous surgery. In 64% of the patients of our study cause remains uncertain. Endoscopic sinus surgery is an effective treatment for maxillary sinus mucoceles with a favorable long-term outcome. http://www.head-face-med.com/content/2/1/29 Fatma Caylakli Haluk Yavuz Alper Can Cagici Levent Naci Ozluoglu Head & Face Medicine 2006, null:29 2006-09-06T00:00:00Z doi:10.1186/1746-160X-2-29 /content/figures/1746-160X-2-29-toc.gif Head & Face Medicine 1746-160X ${item.volume} 29 2006-09-06T00:00:00Z XML Skin diseases on the nose are seen in a variety of medical disciplines. Dermatologists, otorhinolaryngologists, general practitioners and general plastic and dermatologic surgeons are regularly consulted regarding cutaneous lesions on the nose. This article is the second part of a review series dealing with cutaneous lesions on the head and face, which are frequently seen in daily practice by a dermatologic surgeon. In this review, we focus on those skin diseases on the nose where surgery or laser therapy is considered a possible treatment option or that can be surgically evaluated. http://www.head-face-med.com/content/6/1/7 Michael Sand Daniel Sand Christina Thrandorf Volker Paech Peter Altmeyer Falk Bechara Head & Face Medicine 2010, null:7 2010-06-04T00:00:00Z doi:10.1186/1746-160X-6-7 /content/figures/1746-160X-6-7-toc.gif Head & Face Medicine 1746-160X ${item.volume} 7 2010-06-04T00:00:00Z XML Background: Spindle cell carcinoma (SpCC) is a rare, high malignant variant of squamous cell carcinoma (SCC), which shows biphasic proliferation of conventional SCC component and malignant spindle shape cells with sarcomatous appearance. Methods: A case of Spindle cell carcinoma with bone-like calcified materials, occurring at the mandibular molar region of 71-years-old Japanese male patient was presented with gross finding, histological findings and MRI image. To identify the characteristics of the bone-like materials, immunohistochemistry were performed. Results: Histologically, the cancer cells were composed of spindle cells and epithelial cells which form nests with prominent keratinization. Histological findings showed typical histology of the SpCC, however, as an uncommon finding, spatters of calcified, bone-like materials were observed in between the cancer cells. Immunohistochemistry revealed that cancer cells were positive for cytokeratins and vimentin to a varying degree and negative for Desmin, S-100, Osteopontin, BMP-2 or BMP-4. These findings implied that the calcified materials were formed by metaplasia of the stromal cells.DiscussionBone-like materials formation by osseous and/or cartilaginous metaplasia of the stroma in the carcinoma has been reported. However, the detailed mechanism of these metaplasia and affection on the clinical feature, prognosis and therapies are not well established. In summary, we presented an unique case of SpCC, which has not been described in the literature. http://www.head-face-med.com/content/4/1/28 Naoki Katase Ryo Tamamura Mehmet Gunduz Jun Murakami Jun-Ichi Asaumi Goichi Tsukamoto Akira Sasaki Hitoshi Nagatsuka Head & Face Medicine 2008, null:28 2008-12-01T00:00:00Z doi:10.1186/1746-160X-4-28 /content/figures/1746-160X-4-28-toc.gif Head & Face Medicine 1746-160X ${item.volume} 28 2008-12-01T00:00:00Z XML Injuries resulting from the use of angle grinders are numerous. The most common sites injured are the head and face. The high speed disc of angle grinders does not respect anatomical boundaries or structures and thus the injuries produced can be disfiguring, permanently disabling or even fatal. However, aesthetically pleasing results can be achieved with thorough debridement, resection of wound edges and careful layered functional closure after reduction and fixation of facial bone injuries. A series of penetrating facial wounds associated with angle grinder use are presented and the management and prevention of these injuries discussed. http://www.head-face-med.com/content/4/1/1 Lachlan Carter Craig Wales Iain Varley Martin Telfer Head & Face Medicine 2008, null:1 2008-01-23T00:00:00Z doi:10.1186/1746-160X-4-1 /content/figures/1746-160X-4-1-toc.gif Head & Face Medicine 1746-160X ${item.volume} 1 2008-01-23T00:00:00Z XML Sagittal split osteotomy (SSO) is a surgical technique largely employed for mandibular mobilizations in orthognatic procedures. However, the traditional design of buccal osteotomy, located at the junction of mandibular ramus and body, may prevent more extensive sliding between the bone segments, particularly on the advance, laterality and verticality of the mandibular body. The author proposes a new technical and conceptual solution, in which osteotomy is performed in a more distal region, next to the mental formamen. Technically, the area of contact between medullary-cancellous bone surfaces is increased, resulting in larger sliding rates among bone segments; it also facilitates the use of rigid fixation systems, with miniplates and monocortical screws. Conceptually, it interferes with the resistance arm of the mandible, seen as an interpotent lever of the third gender. http://www.head-face-med.com/content/3/1/15 Edela Puricelli Head & Face Medicine 2007, null:15 2007-03-13T00:00:00Z doi:10.1186/1746-160X-3-15 /content/figures/1746-160X-3-15-toc.gif Head & Face Medicine 1746-160X ${item.volume} 15 2007-03-13T00:00:00Z XML Background: Rhinoplasty "open" represents a surgical technique to access to the internal structures of the nose; it is an alternative to more traditional "closed" rhinoplasty. However, both these techniques have some advantages and some disadvantages. In this work the authors describe a case that shows the steps of a new surgical technique: the "semi-open" rhinoplasty. Methods: The "semi-open" technique is performed by making an incision to access on the mucosa of both the nostrils, and through this access we separate the cartilages of the columella from the alar cartilages, debriding them at the domus. With such access we can perform any type of rhinoplasty surgery with functional or aesthetic purposes.DiscussionsTraditional techniques have undoubtedly some advantages and some disadvantages. The "semi-open" technique has the several advantages of the open technique, and it does not involve the presence of post-surgical scars. Conclusions: This innovative technique provides great predictability and minimal postoperative discomfort, with no aesthetic damage. http://www.head-face-med.com/content/8/1/13 Francesco Inchingolo Marco Tatullo Massimo Marrelli Alessio Inchingolo Roberto Corelli Angelo Inchingolo Paolo Flace Raffaele Cagiano Gianna Dipalma Fabio Abenavoli Head & Face Medicine 2012, null:13 2012-04-30T00:00:00Z doi:10.1186/1746-160X-8-13 /content/figures/1746-160X-8-13-toc.gif Head & Face Medicine 1746-160X ${item.volume} 13 2012-04-30T00:00:00Z PDF The traumatic bone cyst (TBC) is an uncommon nonepithelial lined cavity of the jaws. The lesion is mainly diagnosed in young patients most frequently during the second decade of life. The majority of TBCs are located in the mandibular body between the canine and the third molar. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination usually as an unilocular radiolucent area with a "scalloping effect". The definite diagnosis of traumatic cyst is invariably achieved at surgery. Since material for histologic examination may be scant or non-existent, it is very often difficult for a definite histologic diagnosis to be achieved. We present a well documented radiographically and histopathologically atypical case of TBC involving the ramus of the mandible, which is also of possible iatrogenic origin. The literature is briefly reviewed. http://www.head-face-med.com/content/2/1/40 Arsinoi Xanthinaki Konstantinos Choupis Konstantinos Tosios Vasilios Pagkalos Stavros Papanikolaou Head & Face Medicine 2006, null:40 2006-11-12T00:00:00Z doi:10.1186/1746-160X-2-40 /content/figures/1746-160X-2-40-toc.gif Head & Face Medicine 1746-160X ${item.volume} 40 2006-11-12T00:00:00Z XML Background: Titanium and titanium alloys are widely used for fabrication of dental implants. Since the material composition and the surface topography of a biomaterial play a fundamental role in osseointegration, various chemical and physical surface modifications have been developed to improve osseous healing. Zirconia-based implants were introduced into dental implantology as an altenative to titanium implants. Zirconia seems to be a suitable implant material because of its tooth-like colour, its mechanical properties and its biocompatibility. As the osseointegration of zirconia implants has not been extensively investigated, the aim of this study was to compare the osseous healing of zirconia implants with titanium implants which have a roughened surface but otherwise similar implant geometries. Methods: Forty-eight zirconia and titanium implants were introduced into the tibia of 12 minipigs. After 1, 4 or 12 weeks, animals were sacrificed and specimens containing the implants were examined in terms of histological and ultrastructural techniques. Results: Histological results showed direct bone contact on the zirconia and titanium surfaces. Bone implant contact as measured by histomorphometry was slightly better on titanium than on zirconia surfaces. However, a statistically significant difference between the two groups was not observed. Conclusion: The results demonstrated that zirconia implants with modified surfaces result in an osseointegration which is comparable with that of titanium implants. http://www.head-face-med.com/content/4/1/30 Rita Depprich Holger Zipprich Michelle Ommerborn Christian Naujoks Hans-Peter Wiesmann Norbert Kubler Sirichai Kiattavorncharoen Lauer Hans-Christoph Ulrich Meyer Jorg Handschel Head & Face Medicine 2008, null:30 2008-12-11T00:00:00Z doi:10.1186/1746-160X-4-30 /content/figures/1746-160X-4-30-toc.gif Head & Face Medicine 1746-160X ${item.volume} 30 2008-12-11T00:00:00Z XML Background: True unilateral posterior crossbite in adults is a challenging malocclusion to treat. Conventional expansion methods are expected to have some shortcomings. The aim of this paper is to introduce a new technique for treating unilateral posterior crossbite in adults, namely, corticotomy-assisted expansion (CAE) applied on two adult patients: one with a true unilateral crossbite and the other with an asymmetrical bilateral crossbite, both treated via modified corticotomy techniques and fixed orthodontic appliances. Methods: Two cases with asymmetric maxillary constriction were treated using CAE. Results: In both cases, effective asymmetrical expansion was achieved using CAE, and functional occlusion was established as well. Conclusions: Unilateral CAE presents an effective and reliable technique to treat true unilateral crossbite. http://www.head-face-med.com/content/6/1/6 Ali Hassan Ali AlGhamdi Ahmad Al-Fraidi Aziza Al-Hubail Head & Face Medicine 2010, null:6 2010-05-19T00:00:00Z doi:10.1186/1746-160X-6-6 /content/figures/1746-160X-6-6-toc.gif Head & Face Medicine 1746-160X ${item.volume} 6 2010-05-19T00:00:00Z XML
