BACKGROUND Unwanted submental fat (SMF) may result in an unattractive chin profile and dissatisfaction with appearance. An approved and rigorously tested non-surgical method for SMF reduction is lacking. OBJECTIVE To evaluate the efficacy and safety of ATX-101 for the pharmacological reduction of unwanted SMF in a phase III randomized, double-blind, placebo-controlled study. METHODS Patient...

We report a case of predominantly cystic synovial sarcoma partly adherent to the hyoid bone in the submental area. The mass demonstrated posterior acoustic enhancement at sonography and a complex cystic mass with mural nodules and solid septa at CT.

BACKGROUND Liposuction of the neck is currently one of the most common cosmetic surgical procedures. In the present study, the author describes his experience with neck and jowl laser-assisted liposuction. STUDY DESIGN/MATERIALS AND METHODS In this procedure, submental lipodystrophy is treated with an Nd:YAG laser, at a 1,064 nm wavelength. Over a 5-year-period, 82 subjects were treated using...

Submental intubation is an effective alternative technique for airway management in patients with maxillofacial trauma. Compared tracheostomy, it less invasive, but has risks associated potential compromise such as hypoxia due to tube obstruction, collapse, and kinking. To shorten procedure time ensure a reinforced lumen, we used laparoscopic trocar new device submental intubation. A 54-year-ol...

BACKGROUND As experience with vascularized lymph node (VLN) transfer has grown, new VLN sources have become apparent. Descriptive studies have elucidated variable lymph node presence in these donor basins. Yet, no study has evaluated preoperative imaging evaluation between donor sites in patients undergoing VLN transfer. This study was to compare the findings on duplex ultrasonography of the su...

BACKGROUND Inter-foraminal implant placement poses a risk to the sublingual artery as it enters the mandibular midline lingual foramen. Lack of consensus on the source of this artery poses a dilemma to surgeons during management of haemorrhagic episodes. Determination of the exact source of this artery is therefore pivotal. METHODS This was a cross-sectional descriptive study involving 34 adu...

Epidermoid and dermoid cysts represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are found, and teratoid cysts when other tissue such as muscle, cartilage, and bone are present.In this article, we present the case of an epidermoid cyst, with an oral as well as a submental component, i...

The activity of the hypoglossal nerve was recorded during pharyngeal loading in sleeping dogs with chronically implanted cuff electrodes. Three self-coiling spiral-cuff electrodes were implanted in two beagles for durations of 17, 7, and 6 mo. During quiet wakefulness and sleep, phasic hypoglossal activity was either very small or not observable above the baseline noise. Applying a perpendicula...
