Surgery performed by Dr. Cristobal Langdon
The complete surgery of type 3 nasopharyngectomy made by the Dr. Christopher Langdon, international expert rhinologist and founder of the medical scribe company AI Speaknosis, can be seen in the online surgical training app SurgSchoolThis presents a typical scenario of rescue surgery for recurrence of nasopharyngeal carcinoma, where the indication is frequently supported by metabolic findings (PET) and not so much by an obvious macroscopic lesion.
La endoscopic nasopharyngectomy type 3 This extended approach is indicated when the recurrence is located in the nasopharynx with posterior/lateral extension, requiring control of the carotid axis and work around the Eustachian tube, sphenoid base, and pterygopalatine region. Compared to alternatives such as re-irradiation, brachytherapy, or transfacial approaches, endoscopic salvage offers targeted resection with less facial morbidity, although it requires advanced experience in skull base surgery and a robust reconstructive plan in irradiated beds.
Preoperative planning
In post-radiotherapy recurrences, planning is more important than in primary surgery. Dr. Langdon emphasizes a clinical reality: “sometimes you don't see much” and you act based on the PET scan. This necessitates:
- Correlate PET with MRI/CT of the skull base to delineate the clivus/basiesphenoid and its relationship to the fallopian tube and carotid bundle.
- Anticipate the need for multiple biopsies intraoperative, including areas with doubtful uptake (in this case, V2 “shone” on the PET).
- Plan vascular control early: exposure of the pterygopalatine/pterygomaxillary fossa as a first strategic step.
- Designing an entry reconstructive flap. In the video, the flap is already raised and positioned contralaterally before entering the resection, a key decision in an irradiated bed.

Description of the surgical approach
The approach is an extended endoscopic endonasal procedure with lateral control through wide exposure of the pterygopalatine fossa. The technical rationale is twofold:
- Create a corridor that allows for circumferential dissection and deep hemostasis.
- Having a "starting point" for vascular control (branches towards the fallopian tube, ascending pharyngeal artery and carotid environment).
Dr. Langdon insists that this initial step “will be the beginning and will allow us vascular control,” reflecting a skull base mentality: first secure the hemostatic terrain, then resect.
Key surgical steps
Pterygopalatine exposure and vascular control
With the pterygopalatine fossa well exposed, improvisation is minimized when bleeding occurs from small branches leading to the Eustachian tube. In irradiated beds, the planes are less stable and bleed more erratically; anticipating this changes the surgical approach.
Dr. Langdon mentions sealing and dissecting instruments that facilitate bloodless surgery: LigaSure, the aspirator-dissector coagulator, and Coblation. The choice of device is crucial; in rescue surgery, the goal is to maintain a clean field to identify margins and protect critical structures.
PET-guided biopsies
In last-line surgery, taking multiple biopsies is not optional. Here, a V2 biopsy is performed using PET uptake. This procedure serves two purposes: to confirm disease and to avoid unnecessarily extending the resection into neural pathways if there is no actual invasion.
Milling of the base-sphenoid and detachment towards posterior planes
The core technique of the procedure is the careful drilling of the basiesphenoid bone to expose the posterior soft tissue. Dr. Langdon describes it as a “three-handed” operation: endoscope, aspirator, and drill, with retraction/assisted use (lens) to maintain visualization and safety.
This step is critical for two reasons:
- It allows en bloc or semi-en bloc resection of the recurrence and its bed.
- It forces one to live with vascular risk: as one advances “behind the tube” the proximity of the carotid artery appears (and its relationship with the ascending pharyngeal artery and tubal branches).
Carotid artery localization with micro-Doppler
Micro-Doppler is used proactively to locate the carotid artery and "see roughly where it is." Although at that moment "we are far away," its real value lies in maintaining a dynamic reference point as we delve deeper into a field distorted by radiotherapy.
This behavior (looking for the carotid artery before being on top of it) is one of the markers of safe skull base surgery.
Resection of the piece and cleaning of the bed
After turning the piece over, the marked fragment (corresponding to the PET-positive area) is obtained. From there, the focus shifts: securing the bed and "leaving everything as clean as possible."
Bone structures such as vertebrae, clivus, and sphenoid bone are exposed. Dr. Langdon insists on drilling even bone that appears non-cancerous: in an irradiated bed, "it doesn't bleed much" and "it's not that healthy," so removing a layer of bone adds oncological safety and reduces the risk of leaving residual cells.
Critical points and risks
Structures at risk
- Carotid (especially in the region posterior to the fallopian tube).
- Neurovascular bundle of the pterygopalatine fossa and branches towards the tube.
- Region V2 (due to suspected PET and surgical proximity).
- Clivus and deep tissues in irradiated field (risk of poor healing).
Potential complications
- Deep bleeding that is difficult to control.
- Bone necrosis/osteorradionecrosis and poor healing.
- Infection, fistula, and persistent bone exposure if not properly reconstructed.
- Incomplete resection due to undertreatment of the bed.
Prevention is based on early vascular control, systematic Doppler and resection/“refreshing” of the bed with oncological criteria.
Surgical Tips & Pearls
The first move must be strategic: wide pterygopalatal exposure so that bleeding ceases to be an event and becomes a controllable variable.
In PET-guided recurrence, biopsying multiple points avoids both undertreatment and overtreatment.
The micro-Doppler is not for "when you're already on top of it", it's for building a safety map before entering the critical zone.
In irradiated bone, even if it appears non-tumorous, superficial milling of the bone bed increases oncological safety and reduces uncertainty.
If Coblation or LigaSure is available today, prioritizing energy that seals and desiccates with less carbonization improves visibility and reduces diffuse bleeding.
Frequent errors
Going straight to injury without preparing a vascular control runner.
Relying on macroscopic appearance instead of correlation with PET/MRI and targeted biopsies.
Do not use Doppler systematically when working posterior to the fallopian tube.
Delayed or insufficient reconstruction in irradiated beds, with bone exposure and healing complications.
Results and postoperative considerations
The goal of a salvage type 3 nasopharyngectomy is complete resection of the recurrence and a clean bed, knowing that the irradiated area influences the outcome. In this case, the procedure is completed with coverage using... nasoseptal flap, which provides vascularization and protection to the milled bed.
Follow-up should be close, combining serial endoscopic examination and imaging control (including PET according to oncological protocol), especially monitoring for scarring, bone exposure and signs of recurrence.
For whom is this surgery especially useful?
To advanced residents in ENT and rhinology who want to understand the logic of PET-guided salvage surgery.
To young assistants who are entering extended endoscopic skull base surgery and need to internalize vascular control and Doppler use.
To expert surgeons, due to the practical nuances in irradiated beds: choice of energy, bed milling and reconstructive timing.
