Summary
Deep lobe parotid tumors extending into the parapharyngeal space can cause obstructive sleep apnea. Surgical removal led to significant improvements in sleep apnea symptoms and nocturnal hypoxia.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Surgical Pathology
Background:
- Deep lobe parotid tumors are rare and can extend into the parapharyngeal space.
- Airway compromise is a known complication of some salivary gland tumors.
- Obstructive sleep apnea (OSA) significantly impacts patient quality of life.
Observation:
- Two cases of deep lobe parotid tumors causing obstructive sleep apnea are presented.
- Tumors extended into the parapharyngeal space, leading to airway obstruction.
- Patients experienced significant nocturnal hypoxia and OSA symptoms.
Findings:
- Surgical resection of the deep lobe parotid tumors resulted in marked improvement of OSA symptoms.
- Post-operative polysomnography confirmed resolution of nocturnal hypoxic episodes.
- This is the first documentation of pleomorphic adenomas from the deep parotid lobe causing proven OSA.
Implications:
- Deep lobe parotid tumors should be considered in the differential diagnosis of parapharyngeal masses causing OSA.
- Early diagnosis and surgical intervention can effectively manage OSA secondary to these tumors.
- Understanding the relationship between parapharyngeal space pathologies and sleep-disordered breathing is crucial for patient management.
