Summary
Proboscis lateralis is a rare congenital nasal anomaly resulting in incomplete nose formation. Early reconstruction using the proboscis itself is recommended for optimal outcomes in pediatric patients.
Area of Science:
- Craniofacial surgery
- Congenital anomalies
- Embryology
Background:
- Proboscis lateralis is a rare congenital facial anomaly characterized by a rudimentary, off-center nasal structure.
- It arises from incomplete formation of one nasal side, linked embryologically to median facial clefts.
- The anomaly presents as a tube-like appendage along embryonic fusion lines.
Observation:
- This report details a rare case of proboscis lateralis in a 4-year-old female patient.
- The condition involves a unilateral, underdeveloped nasal structure.
- The appendage was located along the fusion line between the anterior maxillary and frontonasal processes.
Findings:
- Proboscis lateralis necessitates early intervention for reconstruction.
- The proboscis itself serves as the optimal graft for heminose reconstruction.
- Delayed procedures in late teens can incorporate cartilaginous or bony support for aesthetic enhancement.
Implications:
- Early surgical management of proboscis lateralis can significantly improve functional and aesthetic outcomes.
- Understanding the embryological basis aids in surgical planning and treatment strategies.
- This case highlights the importance of timely intervention in managing rare craniofacial malformations.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

01:19Muscles that Move the Head
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
