Dysphagia After Partial Horizontal Supracricoid Laryngectomy: A Close Look.

ABSTRACT

Partial horizontal supracricoid laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) is a conservative surgical alternative for laryngeal cancer in the glottic or supraglottic region. Dysphagia and aspiration are frequently reported consequences of this surgery. We describe the case of a 72-year-old male patient diagnosed with squamous cell carcinoma of the larynx (T2N0M0), who underwent SCPL with CHEP reconstruction. The patient was initially fed through a nasogastric tube post-surgery, later replaced by a percutaneous endoscopic gastrostomy (PEG) tube. Swallowing evaluations were periodically conducted in collaboration with a speech therapist using fiberoptic endoscopic evaluation of swallowing (FEES) and videofluoroscopic swallowing study (VFSS). In FEES assessments, the patient consistently presented with laryngeal penetration and possible tracheal aspiration. These findings were confirmed by VFSS. Additionally, a narrowing of the initial segment of the cervical esophagus was observed, caused by a large osteophyte in the anterior region of the C5 vertebral body, compromising the passage of the bolus, and leading to its accumulation above the upper esophageal sphincter and subsequent entry into the airway. Rehabilitation exercises for swallowing were recommended, maintaining an exclusive PEG diet. Three months after rehabilitation, a follow-up VFSS revealed that, for pasty consistency, the accumulation of the bolus above the cervical osteophyte was resolved with multiple swallows, without evidence of penetration or aspiration. Thus, it was possible to introduce oral intake of pasty consistency. Considering the anatomical and physiological complexity of swallowing, along with patient-specific characteristics, predicting the rehabilitation time for reconstructive laryngeal surgery is challenging. This case emphasizes the importance of a collaborative evaluation involving otorhinolaryngologists, speech therapists, and radiologists in studying dysphagia in patients undergoing conservative laryngeal surgeries to adapt and personalize rehabilitation.
