Laryngeal recurrent respiratory papillomatosis can be treated in the office using a 532-nm pulsed KTP laser under local anesthesia while the patient is awake without sedation.

KTP laser treatment of recurrent respiratory papillomatosis in the office
Small RRP lesions
Patient tolerance and/or preference
Bulky RRP lesions
Patient anxiety
Significant gag reflex
Medical comorbidities that contraindicate an in-office procedure
Patient sits in an upright position in a chair. Physician driving the laryngoscope stands on the patient¢s right side while the assistant, who passes the lidocaine drip catheter and laser fiber, stands on the patient¢s left.
Blood pressure and heart rate measurements before the procedure.
Good knowledge of the laryngeal anatomy
Knowledge of KTP laser treatment classifications:
KTP V ¢ Noncontact, angiolysis
KTP 1 ¢ Noncontact, epithelium intact
KTP 2 ¢ Noncontact, epithelium disruption
KTP 3 ¢ Select contact or noncontact, epithelial ablation without tissue removal
KTP 4 ¢ Contact, epithelial ablation with tissue removal
Advantages: Avoids general anesthesia; allows ¢touch-up¢ removal of small RRP lesions
Disadvantages: Not ideal in bulky RRP lesions; not as precise as treatment under general anesthesia
Vasovagal reaction, epistaxis, incomplete removal of RRP lesions, may require multiple procedures, anterior glottic web formation.

This video shows a transotic approach for a cochlear schwannoma in a 59-year-old female who presented with sudden sensorineural hearing loss in her left three years prior. She was found to have subsequent growth of her tumor on imaging and elected to undergo surgery. The transotic approach is a valuable approach within the armamentarium of a skull base team and differs from the transcochlear approach in the handling of the facial nerve. Techniques for ear canal overclosure, eustachian tube packing and mastoid obliteration are also highlighted.
Here, we have a 39 yrs old female with complaints of noisy breathing for last two years post thyroidectomy. Flexible laryngoscopy confirmed bilateral vocal cord paralysis. She was planned for coblation assisted cordectomy.
Patient was taken up for procedure under general anaesthesia. She also started having stridor after induction. Nasopharyngeal intubation with spontaneous breathing technique was used. Entropy leads were placed over forehead to monitor the depth of anaesthesia. Tube position was confirmed with endoscopic view and Benjamin lindohlm laryngoscope was suspended. As the patient was spontaneously breathing, the stridor became more prominent, with stable vitals and the procedure was continued. The vocal cord retractor was fixed and coblation wand was then used with 7:3 settings for ablation and coagulation respectively. The surgical limits were-anteriorly the junction between ant 2/3 and post 1/3 of the vocal cord, posteriorly just anterior to the vocal process of arytenoid to prevent cartilage exposure and post operative granulations. Superely till the ventricle and inferioly till the medial most surface of the subglottis. Laterally approx. 5 mm depth was defined to prevent injury to the superior laryngeal artery branch and further bleeding. Once the final airway was achieved , the topical lignocaine was used to prevent laryngeal spasm post extubation.
The patient was shifted to the ward without oxygen, the voice was assessed on post op day 2.
Patient was called for follow up on post op day 14th and good voice outcomes were achieved.
So lets have a look on some tips & tricks for the safe procedure—–
Nasopharyngeal insufflation technique with entropy monitor will give adequate and safe surgical field
2. Appropriate exposure will help you to delineate the surgical margins
3. Topical anaesthesia before and after the procedure will prevent sudden laryngeal spasm
4. Firm holding of coblation device will help to prevent injury to surrounding structures like anterior 2/3 vocal cord, opposite side vocal cord, medial surface of vocal cord or aryteroid posteriorly
5. Do not ablate more laterally to prevent bleeding, if at all it happens, use patties or coagulation switch for hemostasis.
6. And at the end of the procedure ,use catheter suction to suck out blood clots or saline from the airway if any….
To Conclude-Coblation Assisted Cordectomy( CAC) can be performed safely with good outcomes in case of bilateral vocal cord paralysis using tubeless anesthesia technique without tracheostomy !
We present the harvest of a osteocutaneous fibula free flap for head and neck reconstruction performed at the University of Cincinnati. This reconstructive technique has a wide variety of implications but has found greatest utility in the reconstruction of mandibular defects.
