Boxing involves a high risk of dental trauma due to the impact of enormous external forces against the head. Wearing a mouthguard is, therefore, mandatory. The aim of this study was to evaluate the prevalence of dental trauma as well as the utilization and quality of mouthguards in Swiss boxing clubs. In order to achieve this, data on the mouthguards of 217 boxers in total were collected using questionnaires and examination forms, which were statistically evaluated. Out of the 217 boxers, 75 (34.6%) had already experienced a dental accident, but only 8 (10.7%) of them while practicing their sport. Professional boxers were most frequently affected by dental trauma (p = 0.001). Crown fractures were most often observed, followed by tooth dislocations. All interviewed athletes owned a mouthguard, which they used much more consistently during full-contact sparring (practice fighting) than during regular partner exercises. Most of the boxers used prefabricated mouthguards, which could be individually adapted using the “boil and bite” system. The majority of the athletes received their mouthguards from the boxing club. Impaired speaking when wearing a mouthguard was, by far, the problem most frequently mentioned by the athletes. In terms of these bothering factors, custom-made mouthguards from dentists received the best rating (p = 0.002). The quality of the mouthguard was assessed by evaluating the following criteria: coverage of the buccolabial surface, occlusal support of the opposing dentition, thickness of the occlusal layer, and rounded edges. Of the 215 mouthguards examined, 193 (89.8%) were insufficient (p = 0.002). Despite the observed deficiencies, only a few dental injuries occurred during boxing. This study shows that although basic preventive measures do exist in Swiss boxing, they should be improved substantially by providing better instruction and more information.

Nasopharyngeal angiofibroma (NA) primarily affects adolescent males. The incidence of NA in the elderly, however, is extremely low. The present study describes a 72-year-old male with NA that presented with typical symptoms and radiological findings. The location and extension of the tumor was too lateral and inferior to be effectively resected by an endoscopic approach. Therefore, a combination of endoscopic and open approaches was considered. The tumor was completely resected using an image-guided endoscopic-assisted sublabial and buccolabial incision approach. The post-operative histopathological and immunohistochemical analysis confirmed the diagnosis of NA. The present study demonstrated the occurrence of NA in the elderly, and highlighted the potential of an image-guided endoscopic-assisted sublabial and buccolabial incision approach for the treatment of NA in the elderly.

- CONCLUSIONS: Endoscopic assisted sublabial and buccolabial incision is an optional approach to remove JNA with extensive ITF extension.

Horizontal alveolar augmentation by distraction osteogenesis is an alternative method for reconstructing atrophic alveolar bone. A 65-year-old woman with atrophy of the alveolar rim in the anterior lower jaw, which had inadequate width for implant placement, was presented. Under general anesthesia, vertical and horizontal osteotomies of the buccolabial cortical bone were performed in the canine regions bilaterally. Modified horizontal distraction devices were stabilized to the mandible. Distraction proceeded from the seventh postoperative day at a rate of 0.450 mm twice a day for 6 days. After 3 months, distraction osteogenesis occurred and increased the alveolar width from 2 to 7 mm. Two implants were placed in the distracted areas. Marginal bone resorbtion around the implants was not observed 12 months after implant placement.
- [Functional recovery in hemifacial transplants in rats]. [Journal Article]
- RNRev Neurol 2007 Oct 1-15; 45(7):389-92
- CONCLUSIONS: The hemifacial flap can be transplanted. By repairing the nerves of the allograft, it is possible to achieve its functional recovery, as can be confirmed clinically, electrophysiologically and histopathologically. To date, this is the first evidence of functional recovery following a hemifacial transplant in rats.

- CONCLUSIONS: Garcin's syndrome is a very rare neurosurgical entity. The course of the condition depends on the nature of underlying pathology.

Functional roles of the perioral anatomical structures involved in breastfeeding were examined in newborn rat pups in which the hypoglossal (XII) and facial (VII) nerves had been resected at the neonatal stage. The XII nerve controls tongue movement and is comprised of two functionally distinct branches: the medial branch related to protrusion of the tongue and the lateral branch related to its retraction. Newborn rat pups with bilateral resection of either of the XII nerve components (main trunk: XII-trunk; medial branch: XII-med; lateral branch: XII-lat) failed to suckle milk and did not survive. Unilateral XII nerve-resected neonates showed different milk-suckling capabilities, which thus resulted in differences in survival rate (XII-trunk: 38%; XII-med: 24%; XII-lat: 92%) and postnatal growth during the postnatal 3 weeks until P21. Unilateral and bilateral resections of the VII nerve innervating the buccolabial musculature produced lowered suckling capabilities and retarded postnatal growth, although all pups showed 100% survival. The results indicate a crucial role of the tongue, especially of protruding muscular elements innervated by the XII-med nerve, in breastfeeding. The results also indicate differential effects of the VII and XII nerve components on suckling capability, survival, and postnatal growth of newborn rat pups.
- Three-dimensional structure of the modiolus. A computerized reconstruction study. [Journal Article]
- SMSaudi Med J 2003; 24(8):846-9
- CONCLUSIONS: As the structure has great clinical importance, and satisfactory complete 3-D analysis of the subject is not yet available; we believe that our study presenting the histological and 3-D description of the modiolus will be of great help to surgeons for satisfactory esthetic and functional results during surgical operations related to the oral commissure.

This study evaluated the effects of using a titanium mesh for localized alveolar ridge augmentation. Seven consecutively treated human subjects participated in the study. Clinical, radiographic, laboratory, and histologic/histomorphometric analysis revealed the efficacy of using the titanium mesh in conjunction with intraorally harvested autogenous bone graft and inorganic bovine bone mineral (Bio-Oss). Radiographic measurements detected that a 2.86-mm vertical and 3.71-mm buccolabial ridge augmentation was achieved, while histomorphometry demonstrated that 36.4% of the grafted area consisted of bone. Laboratory measurements revealed 15.08% resorption of the graft for the first 6 months, which appeared to consolidate after placement of the implants. Exposure of the mesh did not appear to compromise the result.

- Endoscopic laser-assisted excision of juvenile nasopharyngeal angiofibromas. [Case Reports]
- AOArch Otolaryngol Head Neck Surg 2003; 129(4):454-9
- CONCLUSIONS: Traditional external surgical approaches to large JNAs may result in significant morbidity. Laser-assisted image-guided endoscopic excision of JNAs is a safe and effective minimally invasive surgical treatment. Its distinct advantages include (1) diminished blood loss, (2) superior cosmesis without observed altered facial growth, (3) direct access of skull base with minimal morbidity, and (4) ease of endoscopic follow-up.
