Areas of Expertise
Dr. Rajarshi Bandyopadhyay provides specialist care across oral oncology, facial trauma, TMJ surgery, and maxillofacial reconstruction in Kolkata.
Oral Oncology & Cancer Reconstruction
Oral oncology focuses on the diagnosis, surgical management, and reconstruction of cancers affecting the mouth, jaw, tongue, and surrounding structures. Dr. Bandyopadhyay provides evidence-based oncologic surgery combined with microvascular reconstruction to restore function and appearance.
Conditions Treated
- • Oral cavity cancers (tongue, floor of mouth, buccal mucosa)
- • Benign and malignant oral tumours
- • Head and neck cancers
- • Recurrent oral lesions requiring surgical evaluation
Diagnostic Methods
- • Detailed clinical examination of oral cavity and neck
- • Biopsy and histopathological analysis
- • CT/MRI imaging for staging and surgical planning
- • PET-CT when indicated for advanced cases
Treatment Approaches
- • Surgical resection with clear margin planning
- • Neck dissection when lymph node involvement is suspected
- • Microvascular free flap reconstruction
- • Jawbone and soft tissue restoration
- • Multidisciplinary coordination with oncology teams
Recovery & Follow-Up
- • Hospital stay varies based on procedure complexity
- • Speech and swallowing rehabilitation when needed
- • Regular follow-up for wound healing and oncologic monitoring
- • Long-term surveillance for recurrence detection
Facial Trauma Surgery
Facial trauma surgery addresses injuries to the facial bones and soft tissues caused by accidents, falls, or assaults. Timely specialist intervention is essential to restore facial structure, bite alignment, and function.
Conditions Treated
- • Mandibular fractures
- • Le Fort fractures
- • Panfacial trauma
- • Zygomatic and orbital fractures
- • Soft tissue facial lacerations
Diagnostic Methods
- • Clinical assessment of facial symmetry and bite
- • Panoramic and CT imaging of facial bones
- • Evaluation of dental occlusion
- • Assessment of nerve and soft tissue involvement
Treatment Approaches
- • Open reduction and internal fixation (ORIF)
- • Closed reduction for selected fractures
- • Soft tissue repair and scar management
- • Dental splinting and bite correction
Recovery & Follow-Up
- • Soft diet during initial healing phase
- • Gradual return to normal activities as advised
- • Regular follow-up imaging to confirm bone healing
- • Physiotherapy for jaw mobility when indicated
TMJ Surgery
Temporomandibular joint (TMJ) disorders can cause significant jaw pain, clicking, limited mouth opening, and headaches. When conservative treatment is insufficient, surgical intervention may be recommended.
Conditions Treated
- • TMJ pain and dysfunction
- • Internal derangement of the TMJ
- • TMJ arthritis and degenerative joint disease
- • Recurrent jaw locking
- • Failed conservative TMJ treatment
Diagnostic Methods
- • Clinical TMJ examination and bite assessment
- • MRI or CT imaging of the joint
- • Evaluation of occlusal factors
- • Assessment of muscle and joint function
Treatment Approaches
- • Arthrocentesis and arthroscopy
- • Open joint surgery and disc repositioning
- • Joint reconstruction
- • Total joint replacement for advanced cases
Recovery & Follow-Up
- • Gradual return to normal jaw function
- • Physiotherapy and jaw exercises
- • Soft diet during initial recovery
- • Regular follow-up to monitor joint function
Tumours & Cysts
Oral and jaw cysts and tumours require specialist evaluation to determine whether they are benign or malignant. Early diagnosis and appropriate surgical management help prevent complications and preserve oral health.
Conditions Treated
- • Odontogenic cysts
- • Jaw tumours (benign and malignant)
- • Salivary gland tumours
- • Neck swellings requiring evaluation
- • Recurrent oral lesions
Diagnostic Methods
- • Clinical and radiographic examination
- • Fine needle aspiration or biopsy
- • CT/MRI for extent assessment
- • Histopathological confirmation
Treatment Approaches
- • Enucleation of cysts
- • Surgical excision of tumours
- • Jaw resection for aggressive lesions
- • Reconstruction when extensive tissue removal is needed
Recovery & Follow-Up
- • Healing time varies by procedure extent
- • Regular follow-up imaging and clinical checks
- • Pathology review to confirm complete removal
- • Long-term surveillance for selected lesions
Head & Neck Reconstruction
Head and neck reconstruction restores appearance and function after cancer surgery or severe trauma. Microvascular free flap techniques transfer tissue from one part of the body to reconstruct defects in the face, jaw, or neck.
Conditions Treated
- • Post-oncologic tissue defects
- • Composite mandibular defects
- • Soft tissue defects of face and neck
- • Secondary reconstruction after prior surgery
Diagnostic Methods
- • Assessment of defect size and location
- • Evaluation of donor site options
- • Imaging for surgical planning
- • Multidisciplinary team review
Treatment Approaches
- • Free fibula flap for jaw reconstruction
- • Soft tissue free flaps for facial defects
- • Local and regional flap options
- • Dental rehabilitation planning
Recovery & Follow-Up
- • Intensive monitoring in immediate post-operative period
- • Gradual return to oral intake
- • Speech and swallowing therapy
- • Long-term functional and aesthetic follow-up
Jaw Correction & Orthognathic Surgery
Jaw correction surgery addresses misalignment of the upper and lower jaws that cannot be corrected with orthodontics alone. Procedures improve bite function, facial symmetry, and overall oral health.
Conditions Treated
- • Mandibular prognathism or retrognathism
- • Facial asymmetry
- • Open bite and deep bite
- • Sleep apnoea related to jaw position
- • Post-traumatic jaw deformity
Diagnostic Methods
- • Cephalometric analysis and dental models
- • CT imaging for surgical planning
- • Orthodontic assessment
- • Functional bite evaluation
Treatment Approaches
- • Le Fort I osteotomy (upper jaw)
- • Bilateral sagittal split osteotomy (lower jaw)
- • Genioplasty for chin correction
- • Combined orthodontic and surgical treatment
Recovery & Follow-Up
- • Initial soft diet for several weeks
- • Gradual return to normal jaw function
- • Orthodontic finishing after surgery
- • Regular follow-up for bone healing confirmation
