We have proposed that independent origins of the tympanic membrane (TM), consisting of the external auditory meatus (EAM) and first pharyngeal pouch, are linked with distinctive middle ear structures in terms of dorsal-ventral patterning of the pharyngeal arches during amniote evolution. However, previous studies have suggested that the first pharyngeal arch (PA1) is crucial for TM formation in both the mouse and chick. In this study, we compare TM formation along the anterior-posterior axis in these animals using Hoxa2 expression as a marker of the second pharyngeal arch (PA2)...

A 73-year-old woman was treated 8 years previously for synchronous breast and uterine neoplasms. She presented with a severe sore throat, odynophagia, dysphonia, dyspnoea, ocular irritation and weight loss over the last 3 months. Physical examination revealed ulcerations in the oral cavity, posterior pharyngeal wall and supraglottic larynx, nasal crusting, bilateral conjunctivitis and three cutaneous blisters. A diagnosis of anti-laminin 5 mucous membrane pemphigoid was retained, based on skin biopsy, direct immunofluorescence and immunoprecipitation...

Congenital anastomosis of the external carotid (ECA) and vertebral (VA) arteries is extremely rare. We report a case of right ECA-VA anastomosis diagnosed by computed tomography (CT) angiography. The presumed dilated ascending pharyngeal artery coursed posteriorly and entered the C1 right transverse foramen. The proximal right VA was aplastic, and the C2 right transverse foramen was absent. Based on these findings, we diagnosed congenital anastomosis of the ECA and V3 segment of the VA, which we presumed to represent persistence of the second cervical intersegmental artery...

Velopharyngeal insufficiency (VPI) represents an incomplete closure between the soft palate and the posterior pharyngeal wall. Its etiology can be anatomical (cleft palate), neurologic, or iatrogenic (after adenoidectomy). The evaluation of a VPI begins with a through speech and language assessment and can be complemented by instrumental investigations. VPI treatment relies on its early identification, followed by a specific speech therapy management. Surgery is performed in case of no improvement with speech therapy or in case of an anatomical defect not allowing the child to improve...

PURPOSE: Maxillofacial deformities are always psychologically and physically distressing to the patients and is also challenging to the treating surgeons. The term Micrognathia means a "small jaw". True micrognathia, where the maxilla or the mandibular skeleton does not grow to the full size can be congenital or acquired. Distraction osteogenesis also called as callus distraction or callostasis or osteodistraction or distraction histogenesis is a biological process of regenerating newly formed bone and adjacent soft tissue by a gradual and controlled traction of surgically separated bone segments...

The authors describe a case of gunshot injury in a 26-year-old male patient with an unusual bullet trajectory. The bullet had an entry hole just near the right lateral alar cartilage of the nose, and the trajectory descended through the left side of the neck by route of the hard palate, soft palate, and posterior pharyngeal wall, respectively. Surgical removal of the bullet was achieved with neck exploration. Gunshot injuries of the head and neck necessitate a thorough clinical and radiological evaluation due to the possibility of an unusual bullet trajectory...

Although maxillomandibular advancement (MMA) is an orthognathic surgical procedure used to manage obstructive sleep apnea (OSA) in individuals who are noncompliant with continuous positive airway pressure therapy, simple MMA encounters problems in terms of aesthetic outcomes in Asian populations with preexisting dentoalveolar protrusion. Our current prospective investigation describes changes in posterior pharyngeal space and aesthetic outcomes after counterclockwise rotational orthognathic surgery, which is known to be quite difficult in terms of the maintenance of the skeletal stability in skeletal class II patients with OSA...

We investigated the swallowing function in patients with Parkinson's disease (PD) using deteriorated tongue control because patients with PD frequently exhibit an impaired oral stage of swallowing and the tongue movement affects oral and pharyngeal stage. In total, 201 patients with PD (106 men, 95 women; mean age 70·6 ± 8·0 years; median Hoehn-Yahr Stage III) were studied. The patients swallowed 10 mL of liquid barium under videofluorography, and their oral transit time (OTT) was measured. Based on 20 healthy controls (mean age 70·3 ± 7·8 years) with an OTT + 2 standard deviation (0·89 + 2 × 0·46) of 1·81 s, the patients with PD were divided into 167 patients with an OTT < 1·81 s and 34 patients with an OTT ≥ 1·81 s...

INTRODUCTION: The majority of patients with 22q11.2 deletion syndrome suffer from velopharyngeal insufficiency (VPI). Patients with 22q11.2 deletion syndrome (22qDS) commonly present with a large central velopharyngeal gap in the setting of poor velar and pharyngeal wall motion. The posterior pharyngeal flap is considered the most effective technique to treat VPI in this complex patient group. This study aims to critically evaluate success rates of surgical management of VPI in 22qDS patients and discuss options for management of a failed posterior pharyngeal flap (PPF) with persistent VPI...

BACKGROUND: Management of velopharyngeal insufficiency (VPI) has traditionally involved surgical repair to improve speech. Posterior pharyngeal augmentation using injectable synthetic materials has been advocated. However, outcomes have been equivocal. More recently, autologous fat injection (AFI) has been advocated for correction of mild to moderate VPI. However, long-term efficacy and safety of this procedure remain unsettled. METHODS: A systematic review of the literature was performed...

Obstructive sleep apnea (OSA) is a breathing disorder characterized by the repeated collapse of the pharyngeal airway during sleep. Previous studies have reported that tongue base deformation may be a major contributing factor. However, overnight monitoring of tongue motion in patients with OSA has previously been impracticable. We developed a wearable ultrasound device for prolonged recording during natural sleep of the changes in tongue base thickness (TBT) in patients with OSA. The maximum TBT was fed into a polysomnography system so that physiologic signals and TBT data were simultaneously monitored...
