Anterolateral Thigh Myofascial Fat Composite Flap for Reconstruction of Hemiglossectomy Defects in Obese Patients With Tongue Cancer (ALT-MF)

Anterolateral Thigh Myofascial Fat Composite Flap for Reconstruction of Hemiglossectomy Defects in Obese Patients With Tongue Cancer: A Pilot Study

Tongue cancer is a common malignant tumor in oral and maxillofacial surgery. After surgical resection, it is often accompanied by hemitongue defect. For obese patients (BMI≥30) with tongue cancer, the repair of hemitongue defect is due to thick subcutaneous fat and bloated traditional free flaps, which leads to swallowing and speech dysfunction. As a result, there is still a lack of good clinical repair plans at present, which seriously affects the quality of life of patients. There is an urgent need for safe and efficient targeted repair techniques.

This study intends to retrospectively collect 35 patients with hemitongue defects after surgery for obese (BMI≥30) tongue squamous cell carcinoma in a single center, to compare the repair effects of ALT-MF and traditional free flaps, and to evaluate the postoperative Wada drinking water test scores, speech acuity, etc. of the two groups of patients. This study explores solutions to problems such as bloat, slow functional recovery, and significant donor site damage caused by traditional repair techniques in obese patients, verifies the safety and efficacy of ALT-MF, clarifies the repair mechanism, provides a new strategy for hemitongue defect repair in obese tongue cancer patients, improves the quality of life of patients, and has important clinical value and social significance.

Beskrivelse

Inclusion Criteria:

Foranstaltningsbeskrivelse
Tidsramme
Wada Drinking Water experiment
Tidsramme: 1week、1month、3months、6months、1year、2years after surgery
The drinking process and response are observed. The assessment criteria are divided into 5 levels: able to drink all of the water at one time without choking, level 1 is normal; drinking all of the water in two attempts without choking, level 2 is suspicious; able to drink all of the water in one attempt but with choking, level 3 indicates mild swallowing disorder; drinking all of the water in more than two attempts with choking, level 4 indicates moderate disorder; and frequent choking and difficulty in drinking all of the water, level 5 indicates severe swallowing disorder.

Tidsramme
speech articulation
Tidsramme: 1week、1month、3months、6months、1year、2years after surgery
Speech intelligibility was assessed using a 7-point scale: 7 points for complete speech; 6 points for occasional speech errors; 5 points for intelligible speech with obvious errors; 4 points for speech that can be understood only by careful listening; 3 points for speech that can be understood only by repeated pronunciation; 2 points for speech that is generally unintelligible; and 1 point for speech that is unintelligible.
1week、1month、3months、6months、1year、2years after surgery
Appearance satisfaction
Tidsramme: 1week、1month、3months、6months、1year、2years after surgery
To assess patient satisfaction with postoperative appearance, the 4th edition of the UW-QoL was used: 5 points for normal appearance; 4 points for minor changes in appearance; 3 points for changes that are bothersome but allow the patient to maintain a normal life; 2 points for changes that are bothersome and affect social activities; and 1 point for changes in appearance that make it difficult to interact with others.
1week、1month、3months、6months、1year、2years after surgery
Tumor recurrence and metastasis
Tidsramme: 3 months, 6 months, 1 year and 2 years after surgery
Tumor recurrence or metastasis should also be monitored. CT/MRI scans should be performed every 6 months for 2 years after surgery to monitor for tumor recurrence and metastasis. For patients with suspected recurrence or metastasis, further diagnostic tests, such as pathological biopsy and positron emission tomography-computed tomography (PET-CT), were conducted to confirm the diagnosis and guide subsequent treatment.
