Introduction:
Parapharyngeal space tumors are a small percentage of all head and neck neoplasms. Due to their anatomic location, they represent a therapeutic challenge. To our knowledge, 11 cases of parapharyngeal lipomatous tumors have been reported in the literature.
Case:
A 48 year old male with chief complaints of dyspnea, dysphagia and dysphonia was found to have a parapharyngeal space tumor. He was scheduled to undergo lumpectomy and neck exploration.
Discussion:
Benign tumors represented 70% of all cases. Open neck surgery is considered the gold-standard of treatment.
Conclusion:
It is important to bear in mind the lipomas of the parapharyngeal space to establish an accurate diagnosis and implement timely, appropriate treatment in order to avoid future complications and reduce morbidity and mortality.

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
