Chapter
Lymphangiomas are developmental defects of the lymphatic channels that arise from lymph sacs that are pinched off during development or fail to establish connections with the main lymphatic or venous channels or to a lesser degree from localised lymphatic malformations or obstruction. Based on imaging features, they may be classed as macrocystic, m...

Learning objectives: After studying this article, the participant should be able to: 1. Describe normal ear anatomy and development, and evaluate the patient's ears for differences in shape, size, prominence, and symmetry. 2. Identify common congenital ear deformities, including prominent ear, macrotia, Stahl ear, cryptotia, constricted ear, and l...
Article
We report the case of a male infant born at term with kaposiform hemangioendothelioma (KHE) of the right forearm and coagulopathy. Our case was unusual as it involuted leaving subcutaneous atrophy and prominent veins, which are more commonly observed in rapidly involuting congenital hemangioma. At 3 years of age, the child developed recurrent super...

Background: Cleft lip and/or palate are the most common orofacial malformations. Many studies, especially in developed countries have been conducted on this malformation, but in Burkina Faso, data are scarce and they are not specific to children. The aim of this study was to report the epidemiological , clinical and therapeutic aspects of cleft lip...

Constriction rings are associated with amniotic band syndrome and most often present in the extremities. Constriction bands of the trunk are rare, and a standard of surgical care remains elusive. Traditional methods of constriction ring excision rely on soft-tissue rearrangement with multiple Z-plasties, but renewed interest in linear closure and l...
Article
Background: Cutaneous ulceration is the most common complication of infantile hemangiomas (IHs) seen in a pediatric dermatology practice. Objective: The most effective treatments in our experience are compared to those in the current literature. Methods: The study was a retrospective chart review of therapy of 169 ulcerated IHs at a tertiary c...
Chapter
Anterior scoring of the auricular cartilage in otoplasty has been used for many decades to create the antihelical fold. Many authors propose a minimal access to the anterior surface of the cartilage with subcutaneous scoring of the cartilage in addition to sutures to create the antihelical fold. Others widely expose the anterior surface of the auri...
Article
Poland syndrome is a combination of chest wall deformity and absent or hypoplastic pectoralis muscle and breast associated with shortening and brachysyndactyly of the upper limb. Clinical presentation varies widely; therefore, reconstructive procedures have to be adapted to the deformity, ranging from chest wall stabilization or augmentation, dynam...
Article
Residency education has shifted over the past decade in an attempt to graduate well-rounded physicians. There is a recognition that a physician's abilities must extend beyond medical knowledge. The Royal College of Physicians and Surgeons of Canada introduced the CanMEDS physician competency framework in 2005. The framework provides 7 areas of comp...
Article
Objective: The purpose of this study was to evaluate subperiosteal release of the floor of the mouth (SRFM) musculature to correct neonatal airway obstruction in children with Pierre Robin sequence and to compare this procedure with other surgical options available. Methods: A retrospective chart review of patients who underwent a SRFM for neona...
Article
The purpose of this study is to objectively evaluate donor-site morbidity of the inferior gluteal musculocutaneous flap in teenagers. All cases of breast reconstruction performed between 1996 and 2005 using an inferior gluteal flap were reviewed. Flap size, weight, and pedicle origin were noted. Donor-site morbidity was assessed for scarring, conto...
Article
The authors reviewed 37 children presenting with closed, unstable fractures of the proximal phalangeal head. Fractures were classified as intra-articular (n = 15), including 14 unicondylar and 1 bicondylar, or extra-articular (n = 22), including 20 subcondylar and 2 comminuted subcondylar. Eighteen patients underwent closed reduction with K-wire fi...
Article
Congenital clinodactyly is a lateral deviation of a finger frequently caused by an abnormal middle phalanx (trapezoidal or triangular delta phalanx). The physis extends longitudinally on the short side of the middle phalanx. Resection of the abnormal longitudinal physis and fat graft interposition (physiolysis) has been reported to correct the late...
Article
Sixty-five children presenting with frontozygomatic (lateral brow) dermoid cysts were operated using an upper eyelid crease incision. There were 38 girls and 27 boys age 3 months to 13 years (mean age, 15 months). The lesions were left sided in 32 patients and right sided in 33 patients. Preoperative radiograph or computed tomographic scan performe...
Article
Corrective otoplasty is a commonly performed procedure to change the shape of the auricular cartilage. Many techniques use permanent sutures to maintain the cartilage folding, whereas other techniques rely on cartilage incisions (partial thickness or full thickness). At this institution, a cartilage cutting and anterior scoring technique has been u...
Article
Similar in appearance to preauricular tags but located in the lateral neck, cervical chondrocutaneous branchial remnants are a rather less common and less well known congenital lesion. A retrospective review of admissions at Sainte-Justine Hospital between 1980 and 1993 produced 20 cases of cervical tags, of which 17 were true cervical chrondrocuta...
Article
Between 1983 and 1995, 12 children with Pierre Robin sequence were treated with a subperiosteal release of the floor of the mouth (SRFM) to correct severe upper-airway obstruction (group 1: n = 10) and prolonged feeding difficulties (group 2: n = 2). Eight children had isolated Pierre Robin sequence, while four had associated anomalies. The age at...

Article
Pharyngeal flaps are often used to correct velopharyngeal insufficiency. They produce a permanent partial obstruction of the velopharyngeal space. Respiratory obstruction and obstructive sleep apnea have been reported following this surgery. We undertook a study to find out the incidence of sleep apnea associated with pharyngeal flap surgery. Forty...
Article
All children admitted to our hospital between 1964 and 1991 with a diagnosis of Pierre Robin sequence were divided into three groups according to the severity of their symptoms: group I: adequate respiration in prone position and bottle feeding; group II: adequate respiration in prone position but feeding difficulties requiring gavage; and group II...
Article
Between 1985 and 1991, 13 muscular free flaps with split thickness skin grafts (10 latissimus dorsi, 2 rectus abdominis, and 1 gracilis) were done in 12 patients to cover the weight bearing surface of the foot. Four open wounds were closed primarily and nine unstable scars were replaced with a free flap. A retrospective analysis shows that over the...
Article
We report five cases of children born with forearm wounds associated with motor and sensory losses to the hand and forearm. Their evolution toward muscle retraction is very similar to the classic description of Volkmann's ischemic contracture. These cases should not be confused with upper extremity gangrene of the newborn or aplasia cutis congenita...
Article
Between 1965 and 1986, nine patients were noticed to have significant nasal airway obstruction following surgery for velopharyngeal incompetence (VPI). All had a superiorly based pharyngeal flap. Division of the flap was recommended to correct the posterior obstruction. A complete section of the flap was done in seven cases and lateral port enlarge...

Children are particularly prone to developing moderate to severe Volkmann's ischemic contracture following a supracondylar fracture of the humerus or its treatment. In order to treat such contractures, intensive hand therapy and a gracilis free muscle transfer to the digital flexors were used in 8 patients at an average age of 6 years 2 months. All...
Article
The Pierre Robin anomalad presenting with severe respiratory distress is a difficult situation still associated with a significant mortality rate. A surgical approach based on a new idea is described. The concept is that the musculature of the floor of the mouth is under increased tension and pushes the tongue upward and backward with secondary res...
Article
It is possible to have a good velopharyngeal closure at 8 years of age and slowly deteriorate to present with velopharyngeal incompetence (VPI) at adolescence? Authors disagree on this subject so we undertook a study to find the answer in our cleft palate population. One hundred and seventy-three patients born between 1968 and 1972 with a cleft pal...

... The exact bio-mechanism by which SO 2 exposure during conception increases the risk of congenital ear malformations in offspring is still unclear. The auricle develops from the first and the second branchial arches during the embryonic period of 5-9 weeks [28], so it is generally considered to be the joint site of action for the pathological occurrence of congenital microtia [1]. The influencing mechanism behind various risk factors, including air pollution, may be the abnormal migration of cranial neural crest cells that leads to the occurrence of congenital microtia [29]. ...
... In one of the first reports on the speech outcomes (19) , the authors evaluated, by perceptual assessment, nasoendoscopy and videofluoroscopy, nine children without hypernasality, following surgery for total or partial section of pharyngeal flap, due to respiratory complications. The authors observed that two among the nine children presented return of the symptom. ...
... When all other measures have failed tracheotomy is considered to be the definitive treatment for severe airway obstruction. However, it can be associated with significant morbidity and mortality (0.5-7%) [22][23][24]. The velopalatoplasty aims to treat cleft palates, there are numerous, all depending on the width and the length of the defect. ...
... Prevalence of concomitant congenital anomalies in children with orofacial clefts has been reported to be between 4.3% to 63.4% [5,6]. The central nervous system, head and neck, cardiovascular, musculoskeletal, and urogenital system are commonly affected [2,5,6]. ...
... The complications encountered in our study have been described in other studies, [12,28,29] and they were successfully managed. In Burkina Faso no perioperative complications were reported and it was concluded that surgery for orofacial clefts was safe [30]. Akitoye et al. [20], also confirmed safety of general anaesthesia in their study conducted in a resource limited environment. ...
... C ongenital amniotic band syndrome (ABS) is a complex disorder characterized by a spectrum of rare congenital anomalies, occurring in about 1 of every 10,000 live births. 1 While there are many diverse manifestations of ABS, constriction bands about the extremities are among the most common, with consequential lymphedema, vascular and neural deficits, and aesthetic loss. 2 Few, rare cases of constriction bands involving the thorax and abdomen have been reported. [3][4][5][6][7] Although some of these cases were reported as pelvic constriction bands, none of them described a constriction band within the pelvis. ...
... Regarding breast cancer laterality, the diseases related to developmental factors include Poland syndrome and polythelia. Poland syndrome is a disease characterized by unilateral underdevelopment of a breast or pectoralis muscle, and it occurs more frequently on the right side [16,17]. Polythelia is a congenital condition involving extra nipples and related tissues at birth, which occurs more frequently on the left [18]. ...
... Nineteen patients experienced ulcer healing, 1 patient partially responded, and 1 was a nonresponder. McCuaig et al81 (n = 9) reported a healing time range of 2 to 4 weeks. Metz et al 20 (n = 8) reported a median healing time of 13.5 days (range, 3-21 days). ...
... Resident participation in humanitarian service has been highly controversial and criticized by some as having the potential for unsupervised clinical practice by underqualified trainees [3], while others are concerned about resident´s absence from their training program [4]. To overcome these issues, our missions are part of a university setting following a surgical training program framed by an educational portfolio articulated around a main thematic in each edition. ...
... If this fails, other interventions can be used such as nasopharyngeal and endotracheal intubation (Stern et al., 1972;Wagener et al., 2003;Evans et al., 2011), positive pressure ventilation in the form of continuous positive airway pressure (CPAP; Van den Elzen et al., 2001), head braces or suspension caps (Dennison, 1965), or palatal plates and mandibular traction devices (Davis & Dunn, 1933;Callister, 1937;Pradel et al., 2009;Poets et al., 2019;Poets et al., 2021). In severe cases of persistent airway obstruction, surgical methods such as glossopexy in the form of tongue-lip adhesion (Argamaso, 1992;Evans et al., 2011), subperiosteal floor of mouth release (Caouette-Laberge et al., 2012), mandibular distraction osteogenesis (Dauria & Marsh, 2008;Cheng et al., 2011;Evans et al., 2011), and tracheostomy are indicated (Chigurupati & Myall, 2005;Cheng et al., 2011). Feeding difficulties are managed either by special nipples and cleft palate bottles or by nasogastric feeding tubes in 38% to 62% of infants with RS (Elliott et al., 1995;Li et al., 2002;Evans et al., 2006). ...
