Deficient Mandible
A deficient mandible refers to an underdeveloped or retruded lower jaw that can affect the balance and harmony of the facial profile. This condition may be present from birth or may develop due to growth abnormalities, trauma, or certain medical conditions. A recessed lower jaw can lead to functional concerns such as difficulty in chewing, speech issues, or improper bite alignment, in addition to affecting facial aesthetics.
Treatment for a deficient mandible focuses on restoring proper jaw position and improving overall facial balance. Depending on the severity, procedures may include jaw advancement surgery or other corrective surgical techniques designed to reposition and enhance the structure of the lower jaw. With careful evaluation and modern surgical methods, treatment helps improve both facial appearance and functional outcomes, providing long-term stability and enhanced confidence.
The need for surgery generally falls into two categories:
a. Function Related
- Breathing difficulties (e.g., sleep apnoea)
- Chewing or biting issues
- Speech articulation problems
b. Cosmetic Concerns
- Recessed chin or jawline
- Facial imbalance
- Aesthetic concerns about profile
Pre-Surgical Preparation
The notes outline several steps required before undergoing these surgeries:
- Pre-surgical Orthodontics: Often needed before the actual surgery takes place. Imaging: X-rays and CT scans are required.
- Planning: Virtual surgical planning is performed on a computer, along with model surgery.
- Psychological Evaluation: Conducted to ensure a successful outcome for the patient.


Post-Surgical Recovery
- Hospital Stay: Typically lasts approximately 3-4 days.
- Discharge Criteria: Patients can be discharged once they can start taking soft food orally and can perform day-to-day activities by themselves.
