“…Moebius syndrome is characterized by the dysfunction of the sixth cranial nerve (Souni et al, 2023). Poland syndrome is characterized by the absence of both the major and minor pectoral muscles (Yuan, 2018). Goldenhar syndrome is characterized by an insufficient growth of the first and second branchial arches, resulting in an inadequate unilateral development of the ear, nose, soft palate, lip, and jawbone (Ivănescu et al, 2015).…”

Background: Congenital facial nerve palsy is a rare condition that is typically associated with a traumatic birth event or manifests as a characteristic of a syndrome that necessitates a rehabilitation program. Objective: This report aims to present a rare case and its subsequent outcome after undergoing a rehabilitation program. Case: An eight-month-old infant presented with complaints of an asymmetrical mouth when crying and smiling since birth. The left eye was unable to fully close. No evidence of a syndrome was found. The results of the electromyography of the left facial nerve revealed the presence of partial axonal loss, axonal malfunction, or neuropathy. The patient was subjected to a comprehensive treatment plan, involving rehabilitation programs such as neuromuscular electrical stimulation (NMES) and laser therapy over a period of 18 months. Discussion: It is important to determine if congenital facial palsy is a standalone condition or part of a broader syndrome. Rehabilitation programs, such as NMES and laser therapy, can stimulate the neurons and improve muscle weakness. The House-Brackmann scale demonstrated a clinical improvement, moving from grade V to grade II. With consistent physical therapy, the patient demonstrated improvements in facial expressions and eye closure. Conclusion: NMES and laser therapy, as well as facial massage and biofeedback, are potential treatments for congenital facial palsy due to their efficacy and favorable outcomes.

Rationale: The pectoralis major and minor muscles, located in the anterior chest wall, are crucial for upper limb movements. Patient concerns: Their nonsyndromic absence is rare but significant for surgical procedures involving the axillary and pectoral regions. Diagnoses: Ultrasound can confirm the diagnosis and delimit the extent of the muscular abnormality, detect abnormalities of the costal cartilages, among others. Interventions: This descriptive, cadaveric case report involves a formalin-fixed 57-year-old North American male, with no clinical or family history of similar conditions. The study was conducted at the Human Anatomy Laboratory of the School of Medicine of the Universidad Finis Terrae in Santiago, Chile, in August 2022. Outcomes: We present a cadaveric case of bilateral partial agenesis of the pectoralis muscles discovered during routine dissection. The pectoralis major muscle exhibited only the clavicular portion, with the sternocostal and abdominal portions absent and replaced by a thin layer of connective tissue bilaterally. The pectoralis minor muscle showed partial muscle fibers only in the most distal and inferior portions bilaterally. Lessons: This case report is significant due to the rarity of this condition without accompanying anatomical variations. Understanding this variant is valuable for clinical situations involving the shoulder and thorax region, such as trauma to the proximal third of the humerus, clavicular region, suprascapular region, and anterior chest wall. It may complicate conservative and/or surgical treatments due to different functional and irrigation patterns in the area and is also important for educating future professionals.

A Rare Case of Bilateral Pectoralis Major Muscle Defect and Abnormal Muscle

A 56-year-old female patient with left breast cancer presented at our hospital. Preoperative CT scan showed an isolated bilateral pectoralis major muscle defect and abnormal muscle originating from the entire sternum and inserting in the lower ribs and rectus sheath. Total mastectomy and axillary lymph node dissection were performed. We believe that this case is unique and that others like it have never been reported. If there is a defect in the pectoralis major muscle, reconstructive surgery with a tissue expander is contraindicated. Therefore, preoperative evaluation of the chest wall musculature on imaging is recommended.
