Assessment of the observation management of sialocele after partial superficial parotidectomy

Abstract

Purpose: This study aimed to investigate the usefulness of management of sialocele formation and to evaluate the quality of life of patients under elective management post-parotidectomy. Materials and Methods:A prospective study was performed including patients who underwent postoperative management with either compression therapy or observation. The self-filled questionnaire method was used to assess the quality of life of participants who changed from compression therapy to observation. Demographic and operative data, variables regarding wound complications and scores for quality of life were documented and analysed.Results: A total of 86 patients met the eligibility criteria. The respective rates of sialocele formation within 1 month were 5.3% in the compression therapy group (2/38) and 16.0% in the observation group (4/25), but no significant difference was observed (p = 0.204). Meanwhile, both groups displayed comparable times of needle aspiration and time for sialocele resolution (p > 0.05). Based on 23 valid paired questionnaires, scores for physical and social-emotional function before changing from compression therapy to observation were significantly lower than scores after the change (p < 0.001). Conclusion:The application of observation after partial superficial parotidectomy appears to have acceptable clinical outcomes and considerable improvements in quality of life.

Sialocele formation after partial parotidectomy: Dependent on remnant parotid exposure

“…Persistent sialocele may require repeated aspiration, pressure dressing, anticholinergic drugs, wound exploration, or botulinum toxin injection 6 . Sialocele is generally self‐limited and resolves within 1 month but may sometimes develop into a salivary fistula persisting for months or even longer 7,8 …”

“…6 Sialocele is generally self-limited and resolves within 1 month but may sometimes develop into a salivary fistula persisting for months or even longer. 7,8 Sialocele formation is associated with the extent of parotidectomy. Although it does not occur in total or near total parotidectomy, a high incidence of up to 39% has been reported in partial superficial parotidectomy.…”
