Parapharyngeal space tumors can cause snoring and obstructive sleep apnea (OSA). Surgical removal of these rare tumors effectively cured both conditions in two patients, highlighting the importance of thorough head and neck examinations.
Area of Science:
- Otolaryngology
- Sleep Medicine
- Oncology
Background:
- Obstructive sleep apnea (OSA) and snoring are common conditions with various causes.
- Parapharyngeal space tumors are rare neoplasms located in the upper aerodigestive tract.
Observation:
- Two patients presented with snoring and OSA attributed to parapharyngeal space tumors.
- Oropharyngeal masses were identified, biopsied, and diagnosed as tumors.
- Surgical intervention was performed for tumor resection.
Findings:
- Surgical removal of parapharyngeal space tumors resulted in complete resolution of snoring and OSA in both cases.
- This indicates a direct causal link between these specific tumors and sleep-disordered breathing.
Implications:
- Parapharyngeal space tumors, though rare, should be considered in the differential diagnosis of unexplained snoring and OSA.
- A comprehensive head and neck examination is crucial for early detection of such tumors in patients with sleep-disordered breathing.
- Prompt diagnosis and surgical management can lead to curative outcomes for OSA secondary to these tumors.
