Acute Swallowing Outcomes After Surgical Resection of Oral Cavity and Oropharyngeal Cancers With the Mandibular Lingual Release Approach.

OBJECTIVE: To investigate the incidence, nature, severity, and recovery of early dysphagia in patients following surgical resection of oral and/or oropharyngeal squamous cell carcinoma with a mandibular lingual release approach (MLRA). STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary head and neck cancer center. METHODS: Inclusion of patients' after surgical resection of oral cavity and/or oropharyngeal squamous cell carcinoma via an MLRA between 2012 and 2017. Data collection included acute medical care, enteral feeding, and swallowing outcomes derived from clinical swallow examination and videofluoroscopic swallowing study assessments at baseline, after surgery, and prior to discharge. RESULTS: Twenty-eight patients were eligible for participation (23 males; mean age, 63 years). Baseline clinical swallow examination findings revealed that 32% (n = 9) were tolerating normal diet and fluids preoperatively (Functional Oral Intake Scale [FOIS] = 7). Following surgery, the majority (n = 21, 75%) experienced severe dysphagia (FOIS ≤4), of which 15 were nil by mouth. Twelve patients received a postoperative videofluoroscopic swallowing study, with silent aspiration observed in 9 cases. At discharge, 12 (43%) patients had persistent severe functional dysphagia (FOIS ≤4) with ongoing enteral feeding requirements, of which 7 were nil by mouth. Eleven (39%) were managing diets of modified fluid/diet consistencies (FOIS = 5), and 5 (18%) had mild dysphagia (FOIS ≥6) at discharge. None were able to manage a normal diet. The average length of hospital stay was 27.9 days. CONCLUSIONS: Early dysphagia post-MLRA is a common and often severe complication of surgery. Patients require extended hospital admission with prolonged enteral feeding, which may persist postdischarge. This cohort requires early intervention by speech-language pathology services to aid swallow rehabilitation.

Upper airway assessment and its implications for interventions by respiratory physiotherapists.

BACKGROUND: When noninvasive interventions such as chest physiotherapy fail, then more aggressive interventions for airway secretion clearance with nasotracheal airway suctioning may be required. Clinicians however have to insert the nasotracheal suction catheter "blindly" and the success of being able to trigger a cough and pass through the vocal folds with a suction catheter is low. CASE DESCRIPTION: The patient, a 48-year-old male underwent a heart and lung transplant. Following extubation, the patient developed secretion retention with a weak ineffective cough and swallow and required physiotherapy interventions with frequent "blind" passes of nasotracheal suctioning. OUTCOMES: The patient required nasotracheal suction with frequent multiple failed attempts before successful passage of the suction catheter to trigger a cough reflex and clear secretions. A combined physiotherapist and speech and language therapist intervention during fiberoptic endoscopic evaluation of swallow (FEES) was recorded to both evaluate swallow and passage of the suction catheter. The video illustrated the successful passage of a suctioning catheter through the vocal folds leading to an effective cough and airway clearance. DISCUSSION: We present a case report demonstrating that it is feasible to visualize the upper airways during nasotracheal suctioning as an objective means to guide the more accurate successful insertion of the suction catheter past the vocal folds. Rather than "blind" placement of nasotracheal suction catheters visualization using transnasal laryngoscopy should be useful to increase chances of passing through the vocal folds.
