... 2 In the present patients, perception on the resected side was improved at all measurement points in terms of tactile and cold sensation, although sensitivity on the resected side remained below the normal range. Results for the lower lip, tongue, and chin were broadly similar to those described by Mochizuki et al. 12 Bare bone graft avoids the need for secondary revision and involves epithelialization of the exposed iliac bone surface in the oral cavity. This method carries an expectation of improved gingival perception on 12 reported that recovery of warmth perception in the lower lip, tongue, and chin on the resected side was slower than that of cold or tactile perception. ...

... These observations suggest that CCND1 is a pivotal downstream target gene in EGFR-driven tumorigenesis. Therefore, the genetic statuses of not only EGFR but also CCND1 are needed to predict the therapeutic effects of EGFR inhibitors [19,41]. In our observations, OSCC patients with two concomitant events have the worst prognosis ( Figure 2B, Table 4). ...

... Apart from this, venous congestion, bleeding, partial flap necrosis, and orocutaneous fistula formation were more common in free fibula cases. Other authors reported a similar trend of higher complication rates between bone-containing free flaps compared with pure soft-tissue ones [29][30][31]. We used the fibula as a double paddle for lining and covering both based on different skin perforators. ...

... We summarized our case and 58 previously reported cases of facial palsy after orthognathic surgery [1][2][3][4][5]. The data consisted of 26 males and 33 females (average age was 23.4 years old). ...

... Despite the high incidence, studies indicate that dentists still have difficulties in diagnosing oral The diagnosis must be made based on a thorough anamnesis, identifying risk factors such as the presence or absence of symptoms, delayed healing of mucosal lesions, smoking, drinking, oral HPV infection, long-term exposure to sunlight, old age, genetic diseases and lack of oral hygiene. All of these aspects must be considered together with early diagnosis [24][25][26][27][28][29][30][31][32][33][34][35][36] . ...

... They are most often localized at the lower extremities, however the facial localization prevailed during the first part of the 20 th century [3,4]. Actually, erysipelas is among the rare infections causing acute inflammatory redness of the face [5,6]. Cellulitis and erysipelas are usually thought to be caused by group A streptococci, and other microorganisms such as Staphylococcus aureus may be less frequent causes [2]. ...

... Sleep apnea is a common disorder with significant adverse health consequences. 1 The narrowing of airway causes increase in negative intrathoracic pressure during sleep, which results in sleep fragmentation and excessive daytime somnolence. The prolonged consequences are obesity, glucose intolerance, hypertriglyceridemia, and hypertension, described as a deadly quartet. ...

... Most oral cancers are preceded by precursor conditions collectively identified as "oral potentially malignant disorders" (OPMD). This risk of malignancy in an OPMD can be present in a lesion during the initial diagnosis or can develop later [9]. Therefore, it is of paramount importance that patients diagnosed with OPMD are investigated with biopsy and followed up with adequate time intervals to prevent and or early detect malignant transformation. ...

... The participants comprised 296 men and 712 women, with a mean age of 28 years (13)(14)(15)(16)(17)(18)(19) years, n=144; 20-29 years, n=483; 30-39 years, n=236; 40-49 years, n=102; 50-59 years, n=39; ≥60 years, n=4). ...

... By contrast, for advanced (late stage T2 to T4) and posterior region cancers, multidisciplinary combination therapy with preoperative 5FU intra-arterial chemoradiotherapy (5FU 100 ~ 300 mg for 21 days) with cannulation from the super cial temporal artery followed by surgical treatment in the form of maxillary resection and neck dissection is preferred. [9] The radiation dose is 40 to 50 Gy for primary lesions and 30 to 40 Gy for cervical lymph node metastasis. The maxillary resection line is determined preoperatively according to the tumour extension. ...
