One of the most common signs of tiredness or fatigue is yawning. Naturally, identification of fatigued individuals would be helped if yawning is detected. Existing techniques for yawn detection are centred on measuring the mouth opening. This approach, however, may fail if the mouth is occluded by the hand, as it is frequently the case. The work presented in this paper focuses on a technique to...

Lip synchronization is the determination of the motion of the mouth and tongue during speech. It can be deduced from the speech signal without phonemic analysis, and irrespective of the content of the speech. Our method is based on the observation that the position of the mouth over a short interval of time can be correlated with the basic shape of the spectrum of the speech over that same inte...

Speech animation synthesis is still a challenging topic in the field of computer graphics. Despite many challenges, representing detailed appearance of inner mouth such as nipping tongue’s tip with teeth and tongue’s back hasn’t been achieved in the resulting animation. To solve this problem, we propose a method of data-driven speech animation synthesis especially when focusing on the inside of...

BACKGROUND AND PURPOSE To prospectively investigate the impact of different patients' characteristics on quality-of-life (QoL) after (chemo)radiation for oropharyngeal cancer (OPC). MATERIALS AND METHODS Between 2008 and 2011, 207 patients were treated with 46-Gy of (chemo)-IMRT followed by a boost by means of IMRT, brachytherapy (BT), or Cyberknife (CK). QoL-assessment was performed using th...

PURPOSE To report successful awake insertion of the intubating laryngeal mask (Fastrach) and subsequent tracheal intubation through it, in a patient with predicted difficult tracheal intubation, due to limited mouth opening, and difficult ventilation through a facemask, due to a large mass at the corner of the mouth. CLINICAL FEATURES A 53-yr-old woman with a large post-gangrenous mass on the...

The objectives of the study were to evaluate the outcome of Gap arthroplasty and Interpositional arthroplasty in terms of mouth opening for management of TMJ ankylosis. This Quasi experimental study was carried out in Oral & Maxillofacial Surgical unit, Khyber College of Dentistry, Peshawar from May 2006 to August 2007. Sixty patients of TMJ ankylosis seeking treatment for the first time, irres...

The internal derangement of the temporomandibular joint (TMJ) represents 8% of all cases of temporomandibular disorders (TMD) posing difficulties to establish an accurate diagnosis and treatment because of its low prevalence. This article presents the case of an 18-year-old Caucasian female patient who came to our Orofacial Pain and TMD Outpatient Service with complaints of intense pain on the ...

OBJECTIVE To determine the effect of duration of application of mouth gag on Temporomandibular (TM) joint pain and trismus after tonsillectomy. STUDY DESIGN Descriptive study. PLACE AND DURATION OF STUDY Department of ENT and Head and Neck Surgery, Combined Military Hospital, Nowshera, from February to July 2012. METHODOLOGY A total of 40 patients undergoing tonsillectomy, in mouth openin...

A group of 248 girls, aged 15-16 years, were randomly selected and examined both clinically and by questionnaire with regard to the signs and symptoms of temporomandibular disorders (TMD), generalized joint laxity (GJL), range of mandibular opening, temporomandibular joint (TMJ) hypermobility and presence of oral parafunctions. The prevalence of GJL was 43% and that of TMJ hypermobility (TMJH) ...

BACKGROUND The orofacial musculature plays a pivotal role in maintaining a balance in positioning of the teeth and any imbalance which occurs in this , results in malocclusion. Lingual frenum is a soft tissue structure which tethers the ventral surface of the tongue to the floor of the mouth. OBJECTIVE This study was performed to analyze the lingual frenal lengths in skeletal class I, class I...
